Multilin DGCR Recloser
Chapter 1: Introduction
Introduction
Overview
The DGCR is a microprocessor-based unit that belongs to the Distribution Grid Controller
family, and it is designed as a Recloser Controller controller. This device is intended to
control and monitor different types of medium voltage DGC Recloser Controllers.
Description of the DGCR Controllers
The distribution feeders are equipped with feeder DGC Recloser Controllers (pole-top, padmount) that are typically installed at the source end of the feeder. Distribution circuits
called “laterals” are connected between two consecutive feeder switches. They are
protected by over-current fuses and they are not automated. A typical distribution feeder
layout is depicted in Figure below.
MULTILIN DGCR RECLOSER – INSTRUCTION MANUAL
1–1
DESCRIPTION OF THE DGCR CONTROLLERS
CHAPTER 1: INTRODUCTION
Figure 1-1: Typical distribution feeders layout
As mentioned before, the DGC Recloser Controller is intended to control reclosers. The DGC
Recloser Controllers are usually located on the trunk of the distribution feeder or in the
substation.
The controller is equipped with 6 voltage and 3 current inputs that can be connected to
voltage and current transformers respectively, or to any other voltage and current sensors
with AC outputs within the specified voltage and current ranges. The controller uses two
auxiliary contacts (52a and 52b) to detect open/close Recloser Controller position, and
produce an alarm flag in case of the contacts discrepancy. This is implemented in a
hardcoded logic producing output flags that can be used to build user defined logic.
The DGCR is equipped with a set of standard function elements available for the user
through inputting related setting values. Additional functions that are not part of the
standard DGCR element set can be easily configured and implemented using FlexLogic™
functionality.
The controller is equipped with MDS radio that securely transmits data to the subscribed
distribution automation devices, relays, SCADA, etc. The transmission uses DNP 3.0
protocol. The figure below depicts the section of a distribution feeder, where a DGC
Recloser Controller controller is used:
Figure 1-2: DGCR used as a feeder Recloser Controller controller
The controller is equipped with the following AC inputs:
•
6 PT inputs (Ph-Ph / Ph-N configurations)
•
3 CT inputs (Phase currents)
The important function of the DGC Recloser Controller is to provide voltage and power
measurements, voltage- and current-based computations, as well as several other digital
parameters at the local point. All this information can be transmitted to the remote user.
1–2
Main Functions of the Controller
The DGCR provides two modes of operation:
•
Remote mode
•
Local mode
The mode can be selected only by using the faceplate pushbutton. When in Remote mode,
the DGCR accepts remote commands to operate the DGC Recloser Controller. When in
Local mode, remote commands are blocked and only local commands can be executed.
The local commands are available only at the DGCR faceplate (pushbuttons, keypad and
LED).
The DGCR provides two types of the open/close command execution:
•
Manual
•
Auto
In Manual, the user is directly issuing an open or a close command to the controller,
however all the enabled protection elements are active. In Auto, the commands are
executed by programmable function elements that are running on the controller. Both
(open and close) commands are interlocked with various detection and block functions.
The DGC Recloser Controller controller is capable of measuring three phase voltages and
currents from the electric distribution line. Based on the measured quantities, it can
perform the following:
Protection Functions
•
Phase Instantaneous Overcurrent
•
Phase Timed Overcurrent
•
Neutral Instantaneous Overcurrent
•
Phase Overvoltage
•
Phase Undervoltage
•
Phase Voltage Unbalance
AC Parameters Level Detections
•
Power Loss
Automatic Logic Functions
•
Auto Reclosing
•
CLP (Cold Load Pickup)
PROTECTION FUNCTIONS
Phase Instantaneous Overcurrent:: The controller provides a technique of specifying the
instantaneous overcurrent condition for the DGC Recloser Controller, and generates a flag
during overload conditions. The flag may produce Alarm, Latched Alarm or Trip condition.
The flags are generated and reported to the master host via the radio communications.
Phase Timed Overcurrent: The controller provides a technique of specifying the timed
overcurrent condition for the DGC Recloser Controller. The user can select different
overload curves as a part of the setup procedure for the actual application. During the
overload condition the controller generates a flag. The flag may produce Alarm, Latched
Alarm or Trip condition. The flags are generated and reported to the master host via the
radio communications.
Neutral Instantaneous Overcurrent: The controller provides a technique of specifying the
maximum allowed neutral current level above which the controller generates a flag to
indicate abnormal ground fault condition. The flag may produce Alarm, Latched Alarm or
Trip condition.
Phase overvoltage: The controller provides a technique of setting the maximum phase
voltage level, above which the controller generates a flag to indicate abnormal
overvoltage condition. The flag may produce Alarm, Latched Alarm or Trip condition.
1–3
Phase undervoltage: The controller provides a technique of setting the minimum phase
voltage level, below which the controller generates a flag to indicate loss of potential
condition. The flag may produce Alarm, Latched Alarm or Trip condition.
Phase Voltage unbalance and phase loss: The controller provides a technique of setting
the maximum negative sequence voltage level, above which the controller generates a
flag to indicate voltage unbalance condition. Another (higher) maximum negative
sequence voltage level can be set above which a phase loss flag will be generated. The
flag may produce Alarm, Latched Alarm or Trip condition.
AC PARAMETERS LEVEL DETECTIONS
Power Loss: The controller provides a technique of specifying minimum load current (xCT)
threshold and minimum voltage (xVT) threshold. When both quantities are below the
threshold (pickup) level, the DGCRwill generate a flag representing power loss.
AUTOMATIC LOGIC FUNCTIONS
Auto Reclosing: The Auto reclosing element provides a good mechanism to eliminate
temporary fault conditions. The DGCRcan be programmed to create up to four reclosing
shots upon the fault detection. If after the final programmed shot the fault condition still
exists, the recloser will go into the lockout state.This DGC Recloser Controllerfeature can be
used to sectionalize faulty segments of the feeder by opening the feeder switches. In that
case, actions of the feeder switches have to be synchronized with the recloser sequence.
CLP Cold load pickup: The CLP function is used to avoid fault detections and tripping under
energizing or inrush conditions. When CLP operates, this can produce two effects: raising
of the PH TOC PKP level and blocking of the IOC, UV and OV protection elements. The Cold
Load pickup provides two different working ways:
- Time Block
- Multiplier factor
When CLP is programmed, the energizing process is detected by the transition from a ‘no
voltage & no current’ state to a ‘voltage and current present’ condition.
Time Block selected: After a CLP condition is detected, the time overcurrent functions
are blocked during the period of time programmed in CLP function.
Multiplier factor selected: Each Overcurrent element is provided by a setpoint to
indicate the factor at which the pickup threshold of the function shall be increased
under inrush conditions. If the current magnitude measured is higher than this
setpoint, the element will operate.
COMMUNICATION CAPABILITIES
The DGC Recloser Controller can measure/compute electrical quantities, detect the status
of the grid equipment and produce various alarms and events. This information can be
sent to the distribution center by means of the Distributed Network Protocol (DNP)
communications. In addition, the DGCR can receive different status information and
commands through the DNP.

The DGCR calculates the 3ph power based on currents from Wye connected CTs, and
either voltage inputs from Wye connected PTs, or Delta connected PTs. In addition, two PTs
or either only one PT can be used. The controller has to be configured for different PT
connections in order to compute the 3ph power properly. The DGC Recloser
Controller provides DFT and RMS measurements. The internal metering process is
executed at the internal frequency rate of 1 /4 of a full cycle.
MONITORING AND CONTROL FUNCTIONS
The DGC Recloser Controller is able to monitor the recloser state based on auxiliary input
52a /52b provided by the feeder recloser. The recloser can also be configured for several
external inputs for monitoring possible errors provied by the recloser:
- Low charge limit switch (LCL)
- Spring Charge limit (SCL)
- Disconnect Closed & Latched (DCL)
- Open visual disconnect contact
These inputs can be used to inhibit any possible local and remote closing and opening
commands to the recloser.
The controller is able to monitor other external states as low battery conditions, high and
low ambient temperature (if the order code included an RTD input card), etc.
Maintenance Elements
The maintenance elements provide alarms to the system based on:
•
Maximum number of closing/opening executed commands per period of time
•
I2t measurements per feeder.
Data Logger
The DGCR provides data logger capabilities. The data logger stores the current and voltage
measurements of three phases per feeder at every minute (the interval is configurable). It
can also store the 3 Ph active and reactive power. A minimum of 72 hours should be stored
for statistical features.
There are two more buffers containing information over the largest current values
reached.
•
The largest value per hour is also stored in the ‘peak hourly register’. A minimum of 72
values should be stored for statistical features.
1–5
•
The largest value per 72 hour is also stored in the ‘peak 72 hour register’ buffer.
Event Recorder
The DGCR can store up to 256 consecutive events. Operate and dropout events of fault
detection functions can be enabled or disabled by settings. A snapshot of the phase
voltage/current and power metering can also be included and stored at each Event.
Some of events and alarms include the following:
•
Remote mode
•
Local mode
•
Remote/Manual Close command
•
Remote/Manual Open Command
•
Recloser opened/ closed / failed
•
Overload events

DGCR STATUS LEDs: Three LEDs indicating the DGCR status: “In-Service”, “Alarm”, and
(communications) “Comms OK” are placed in the upper left corner of the DGCR front panel.
IN SERVICE:
The DGCR is operational and functioning properly when the “In-Service”
LED shows green. The LED turns off upon detection of an internal
firmware or hardware error. The product is not programmed when
shipped, and the “In-Service” LED will not light upon power up. The LED
will turn on green upon selecting the “Ready” setting under the S1
INSTALLATION/PRODUCT STATUS menu.
ALARM:
The “Alarm” LED turns orange upon detection of either an internal

The communications LED, is a bi-color LED, meaning that it will show
green when the transmit/receive channels are set and the DGCR is
communicating with another smart device or SCADA. This LED will turn
orange if the communication channels – communication card failure, or
communication channels - are not working properly.
4 X 20 CHARACTER LCD
The DGCR has an LCD with 4 lines of 20 characters, that allows visibility under varied
lighting conditions. When the keypad and the display are not being used, system
information is displayed after a user-defined period of inactivity. Pressing the keypad when
the screen shows the default display returns the display to the last available message
before the default screen activated. Any DGCR control actions, as well as element
operations, are displayed automatically, overriding any target message displayed at that
time. The display and the navigation keypad are conveniently located to provide the user
easy access to any settings, actual values, status, monitoring tools, or statistics.

Now that the Master Reset Password has been programmed, enter it again to log in to
the Master Access level. The Master Level permits setup of the Remote and Local
Passwords. If the Master Reset Password has been lost, record the Encrypted Key and
contact the factory to have it decrypted.
3.
With Master Level access, the user may disable password security altogether, or
change the Master Reset Password.
4.
The Master Access level allows programming of the Remote Settings and Remote
Control passwords. These passwords are initially set to a Null value, and can only be
set or changed from a remote user over RS485 communications. Remote Passwords
must be 3 to 10 characters in length.
3–25
SOFTWARE SETUP
3–26
5.
Initial setup of the Local Settings and Local Control passwords requires the Master
Access level. If Overwrite Local Passwords is set to YES, Local passwords can be
changed remotely only (over RS485). If Overwrite Local Passwords is set to NO, Local
Passwords can be changed locally only (over USB or keypad). If changing Local
Passwords is permitted locally, the keypad user can only change the Local Passwords
if they have been changed from the initial NULL value to a valid one. Local Passwords
must be 3 to 10 characters in length.
6.
If any Remote Password has never been set, that level will not be attainable except
when logged in as the Master Level. The same logic applies to the Local Passwords.
7.
When passwords have been set, the user will be prompted to enter the appropriate
password depending on the interface being used (remote or local), and the nature of
the change being made (settings or control). If the correct password is entered, the
user is now logged into that access level over that interface only. The access level
turns off after a period of 5 minutes of inactivity, if control power is cycled, or if the
user enters an incorrect password.

Line currents and line voltages are filtered values used for the control algorithm. The
integration is based on an IIR filter over the last 10 measurements. For abrupt changes in
metering, higher than twice of the pickup value, a quick update over these registers are
made. Displayed metered quantities are updated approximately three (3) times a second
for readability.

A4 MESSAGES
A4 Messages
Target Messages
Target messages are automatically displayed for any active condition on the relay such as
pickups, trips, or alarms.
The relay displays the most recent event first, and after 5 seconds will start rolling up the
other target messages until the conditions clear and/or the RESET command is initiated.
The Target Messages can be reviewed by pressing either the MESSAGE UP or MESSAGE
DOWN key. If a RESET command is not performed but any of the other faceplate
pushbuttons is pressed, the display will not show the target messages unless the user
navigates to ACTUAL VALUES > A4 TARGET MESSAGES, where they can be reviewed. If the
target messages have not been cleared before the user presses a pushbutton different
from “RESET”, they will reappear on the screen after the time specified under the
SETPOINTS > S1 PRODUCT SETUP > S1 FRONT PANEL > MESSAGE TIMEOUT setting, that will
start timing out from the last pressed pushbutton. The following shows the format of a
typical Target Message:

Self-Test Errors
The relay performs self diagnostics at initialization (after power up), and continuously as a
background task to ensure that the hardware and software are functioning correctly.
There are two types of self-test warnings indicating either a minor or major problem. Minor
problems indicate a problem with the relay that does not compromise protection of the
power system. Major errors indicate a problem with the relay which takes it out of service.

CAUTION:
A4 MESSAGES
Self-Test Warnings may indicate a serious problem with the relay hardware!
Upon detection of a minor problem, the relay will:
•
Display the error on the relay display.
•

Clock
The DGCR has an internal real time clock that performs time stamping for various features
such as the event and transient recorders.
Time synchronization priority uses Modbus or DNP commands as follows:
Synchronization commands are all eventually translated into a MODBUS function, and as
such are blocked from the MODBUS layer as required.
There is no prioritization amongst synchronization commands. A synchronization
command issued from DNP for example, can be directly followed by another from
MODBUS, for example.

With DLS Enabled, the main CPU has to maintain the information regarding
AV.m_DaylightSavingsActive, because it is necessary in the communications CPU to
translate from local time to UTC in 61850 protocol. In addition, if SNTP is enabled, the
main CPU will receive UTC time from the communications CPU and it needs to apply this
in order to pass it to local time.
Without any other synchronization, DLS correction is applied only at 0200 hours on
daylight saving months.

Password security
Password security features are designed into the relay to provide protection against
unauthorized setting changes and control. The relay has programmable passwords for
both Local and Remote access, which can be used to allow settings changes and
command execution from both the front panel and the communications ports. These
passwords consist of 3 to 10 alphanumeric characters. The Local and the Remote
passwords are initially set after entering in a Master Reset Password (MRP). The Master
Reset Password (MRP) is set to “NULL” when the relay is shipped from the factory. When the
MRP is programmed to “NULL” all password security is disabled.. The remote user may
choose to allow the local user to change the local passwords.
Each interface (RS485, USB, and front panel keypad) is independent of one another,
meaning that enabling settings access on one interface does not enable access for any of
the other interfaces (i.e., the password must be explicitly entered via the interface from
which access is desired).
The EnerVista DGCR Setup software incorporates a facility for programming the relay’s
passwords as well as enabling/disabling settings access. For example, when an attempt is
made to modify a settings but access is restricted, the program will prompt the user to
enter the password and send it to the relay before the settings can actually be written to
the relay. If a SCADA system is used for relay programming, it is up to the programmer to
incorporate appropriate security for the application.
Aside from being logged out of security, which allows the user to read settings and actual
values only, three levels of security access are provided: settings Level, Control Level, and
Master Level. The settings and Control Levels can be attained either locally using the Local
passwords (USB port and keypad), or remotely using the Remote passwords (RS485 port).
The user can have either settings or Control Level active, but not both simultaneously from
the same interface. The Master Level is used for setting and resetting of passwords, and
includes all settings and Control Level access rights. The Master Level cannot be attained
from the keypad. The Master Reset Password must be 8 to 10 characters in length, and
must contain at least 2 letters and 2 numbers. The Master Level can define whether the
local user is permitted to change Local Passwords without having to enter the Master
Level. The Master Reset Password is encrypted, and is not viewable from the keypad. If the
Master Reset Password is lost, the user should contact the factory to decrypt the Master
Reset Password.
After password entry, the access level is maintained until a period of 5 minutes of inactivity
has elapsed, after which the password must be re-entered. A power-loss or entering in the
wrong password will log the user out of security.

RS485 interface
The DGCR is equipped with one serial RS485 communication port. The RS485 port has
settings for baud rate and parity. It is important that these parameters agree with the
settings used on the computer or other equipment that is connected to these ports. This
port may be connected to a computer running the EnerVista DGCR Setup software. This
software can download and upload setting files, view measured parameters, and upgrade
the device firmware. A maximum of 32 -series devices can be daisy-chained and
connected to a DCS, PLC, or PC using the RS485 port.
Select the Settings > Communications > Serial Ports menu item in the program, or the
SETTINGS > S1 PRODUCT SETUP > COMMUNICATIONS > RS485 path on the display, to
configure the serial port.
Figure 5-4: Serial port configuration settings
The following settings are available to configure the RS485 port.
BAUD RATE
Range: 9600, 19200, 38400, 57600, 115200
Default: 115200
This setting specifies the baud rate (bits per second) for the RS485 port.
PARITY
Range: None, Odd, Even
Default: None
This setting specifies the parity for the RS485 port.
Modbus
The Modicon Modbus protocol is supported by the DGCR. Modbus is available via the
RS485 serial link (Modbus RTU). The DGCR always acts as a slave device, meaning that it
never initiates communications; it only listens and responds to requests issued by a master
device. A subset of the Modbus protocol format is supported that allows extensive
monitoring, programming, and control functions using read and write register commands.
Refer to the DGCR Communications Guide for additional details on the Modbus protocol
and the Modbus memory map.
The Modbus server can simultaneously support two clients over serial RS485. The server is
capable of reporting any indication or measurement and operating any output present in
the device. A user-configurable input and output map is also implemented.
The DGCR operates as a Modbus slave device only
Select the Settings > Communications > Modbus > Protocol menu item in software, or
the SETTINGS > S1 PRODUCT SETUP > COMMUNICATIONS > MODBUS PROTOCOL path to set
up the modbus protocol as shown below.
Figure 5-5: Modbus protocol configuration settings
The following Modbus settings are available:

S1 PRODUCT SETUP
MODBUS SLAVE ADDRESS
Range: 1 to 254 in steps of 1
Default: 254
This setting specifies the Modbus slave address . Each device must have a unique
address from 1 to 254. Address 0 is the broadcast address to which all Modbus slave
devices listen. Addresses do not have to be sequential, but no two devices can have the
same address or conflicts resulting in errors will occur. Generally, each device added to
the link should use the next higher address starting at 1.
Please refer to the DGCR Communications Guide for details on how to set up the Modbus
communications protocol.

One three-phase current input and two three-phase voltage inputs are available on the
DGCR for connection to the external measuring transformers. These are programmable
through the Current and Voltage Sensing menus. During normal loading conditions the
three-phase currents and voltages are well balanced. The controller uses currents and
voltages measured on the source side of the recloser to compute the electrical power
(apparent, active, and reactive). The table in the main ACTUAL VALUES/A2 METERING
section shows all electrical quantities measured and calculated by the controller. The
DGCR displays the electrical quantities shown in the ACTUAL VALUES/A2 METERING
subsections, for the Source and Load sides separately.

Current sensing
PATH: SETPOINTS > S2 SYSTEM SETUP > S2 CURRENT SENSING
SENSOR TYPE*
Range: User Sensor, Lindsey Sensor, Fisher Pierce 1301, LSC-XXX-122
Default: User Sensor
This setting defines the type of current sensor connected to the DGC. The DGC provides
ways to connect different types of sensors by applying suitable correction factors.
These kinds of current sensors translate the primary current flowing across the
distribution line into an induced voltage of few volts. The voltage induced in the coil of
the sensor is directly proportional to the alternating current in the primary conductor.
CONDUCTOR DIAMETER*
Range: 0.5 to 1.25 inches in steps of 0.25 inches
Default: 0.53 inches
“CONDUCTOR DIAMETER” is not available with “sensor type” programmed to “Lindsey
Sensor”.
NOTE:
NOTE
This setting is used to include the outside diameter of the distributed line conductor in
inches. This setting is needed due to the relationship between the primary current of the
line and the output voltage of the current sensor is directly proportional to the diameter
of the conductor of the line.
See, Sensor Gain (below) for more information.
For “Sensor Type” selected to “Fisher Pierce 1301” or “LSC-XXX-122”, the gain, offset and
phase shift parameters have been internally hardcoded. Only the conductor diameter
setting is required to be changed by the user.
SENSOR GAIN*
Range: 0.00 to 600.00 in steps of 0.01
Default: 17.52
“SENSOR GAIN” is available when “sensor type” is programmed to “User Sensor” OR
“Lindsey Sensor”.
NOTE:
NOTE
This setting provides the magnitude correction factor between the primary current and
secondary output voltage of the sensor.
In current sensors, the relationship between the current and voltage is usually in the
form:
Ip = K . Esi
Where:
Ip - Primary Current in amperes
K - Conductor Diameter formula
Esi - Secondary Output Voltage
For Lindsey sensors: The K parameter is the value programmed under the ‘SENSOR
GAIN’ setpoint. The ratio between the primary current in amperes and the secondary
value in volts is included under this setting.
For User sensors: The K value is parameterized in the form:
K = (Diameter x Gain) + Offset
Diameter – Primary conductor outside diameter in inches.
Gain – Factor between the primary current and secondary voltage. This value is
programmed into the SENSOR GAIN setting
Offset – This value is programmed into the SENSOR OFFSET Setting.
5–13
S2 SYSTEM SETUP
SENSOR OFFSET*
Default: 77.81
“SENSOR OFFSET” is available only when “sensor type” is programmed to “User Sensor”.
NOTE:
NOTE
This setting provides the offset between the primary current and induced voltage in the
sensor. Usually, sensor manufacturers provide calibration factor curves in the form:
Primary_Current = K x Secondary_Current
Where:
K = (Diameter x Gain) + Offset
See SENSOR GAIN setting for more information on this setting.
SENSOR PHASE SHIFT*
Default: 0
“SENSOR PHASE SHIFT” is available only when “sensor type” is programmed to “User
Sensor”.
NOTE:
NOTE
This setting provides the lagging phase shift between the output voltage of the sensor
and the primary current of the line.
NOMINAL SECONDARY V*
Range: 1.0 to 30.0 V in steps of 0.1 V
Default: 10.0 V
This setting provides the nominal current of the distribution line in the secondary voltage
value. This value is used as a unit reference for the detection functions.For example: A
Lindsey Sensor of 600 A / 10V located in a distributed line with a primary nominal
current of 450 A.The secondary voltage at this nominal current will be: V nominal = 10 *
450 A / 600 A = 7.5 VThis value has to be programmed under this setting.
PHASE CT PRIMARY**
Range: 1 to 6000 A in steps of 1 A
Default: 1 A
This setting defines the rated primary current of the connected current transformer.
PHASE CT SECONDARY**
Range: 1 A, 5 A
Default: 5 A
This setting defines the rated secondary current of the connected current transformer.
* The group of settings: “SENSOR TYPE,” “CONDUCTOR DIAMETER,” “SENSOR GAIN,”
“SENSOR OFFSET,” “SENSOR PHASE SHIFT,” and “NOMINAL SECONDARY V” is available only
if the IO_J Order Code was chosen for slot C.

Open/Close Setup
The Recloser Control feature has a programmable menu where the user can set the
criteria for open and close commands. The DGCR has one dedicated output relay for the
“Open” command and another one for the “Close” command. Depending on ordered
controller, the DGCR may have a number of other auxiliary output relays that can be
programmed to close/open logic as well. The logic diagrams below show how the open
and close commands are individually generated.
Recloser control outputs will energize when the respective close/open request is
generated, unless any blocking condition exists. De-energizing of the outputs is controlled
by the state of the recloser as monitored by its 52a and/or 52b contact and delayed by a
settable period of time. Details are shown in the table below, “Recloser Auxiliary Contacts
and Recloser Operation”.

MODES OF OPERATION
Remote/Local Mode
The REMOTE/LOCAL pushbutton toggles between REMOTE and LOCAL mode of operation.
Each of the two modes is associated with a LED to show the selection. This selection has
absolute priority and it can be made only by operating the REMOTE/LOCAL pushbutton.
Automatic, Manual Mode
The AUTO/MANUAL pushbutton toggles between either AUTO or MANUAL mode of
operation. The Auto and Manual modes are associated with a corresponding LED, which
turns on upon mode selection.
The controller mode can be selected from the faceplate pushbuttons or from the remote
location. Similarly, the operator can issue an Open/Close command using the faceplate
pushbuttons or from the remote location. The SCADA user has Read only access at all
times, regardless of the mode selected. However, issuing commands and selecting AUTO/
MANUAL modes via SCADA is restricted and it depends on the selection as shown in the
“Controller Modes” table below.

In Manual mode, the DGCR controls the recloser by responding to manually performed
commands from the faceplate pushbuttons OPEN and CLOSE.
In Automatic mode, the decision to send a Recloser Open command will made by Control
elements, if it is enabled.
In both modes the DGCR controller sends either Open or Close command to the recloser
using two digital outputs: RLY 1 OPEN and RLY 2 CLOSE.
With Remote mode selected when in AUTO mode, the recloser can be also controlled by
either the OPEN/CLOSE commands sent via communications, or via asserting inputs
configured in the Remote Inputs menu: REMOTE OPEN CMND and REMOTE CLOSE CMND.
The remote control overrides the automatic control. After the remote regulation is
performed, the controller will revert back to automatic mode.
Block Auto mode from Communications (COMM BLOCK AUTO)
The Auto mode can be blocked remotely by asserting the command COMM BLOCK AUTO
via communications. This can be done only by using the EnerVista DGCR Setup program
while in Remote control. In this case the recloser can be controlled only remotely. This
command is not visible on the HMI.
Save Block Auto from Communications (SAVE COMM BLK AUTO)
While in Remote mode, the user can select to keep the Auto mode blocked during loss of
communication or loss of power to the DGCR, by setting the command SAVE COMM BLK
AUTO, to “Enabled”. This will keep the Auto mode blocked after the communication or the
power to the DGCR has been restored.
Unblock Auto mode from Communications (COMM UNBLOCK AUTO)
Both the COMM BLOCK AUTO and the SAVE COMM BLK AUTO selections will reset upon
issuing COMM UNBLOCK AUTO command. This command is not visible on the HMI.

Battery backup
The DGCR is capable of controlling the recloser in different conditions including power loss.
The power loss can occur if the feeder circuit breaker opens up or there is a distribution
grid blackout. During all power loss conditions, the DGCR is supplied from a backup
battery. It is sized to keep the DGCR running for 8 hours. During normal running conditions,
the battery is connected to the charger. Switching to different modes of operation is
controlled by a standard IO-E module. This module is inserted in the second slot of the two
DGCR racks, reserved for IO-E modules. The hardware described above is referred to as
DGCR Battery Backup System (BBS).
The battery is a Sealed Valve Regulated Lead Acid (SVRLA) battery. A slow “3 step charging
cycle” is recommended for optimal charging of SVRLA batteries. Improper charging is
among the most common problems of premature failure of Lead Acid batteries. The
preferred three step charging procedure is common for SVRLA batteries and consists of a
constant current step followed by two steps of constant voltage. In the first step, BULK
step, a constant current is applied to the battery until the battery voltage reaches a level of
80% State of Charge (SOC). The next step of charging is referred to as the TOP OFF or
ABSORPTION step, and holds the 80% SOC voltage constant until the battery is not
accepting any more charge (or until a pre-set timer in the controller has expired). At this
point, the voltage is dropped to a new level and held constant in what is called the FLOAT
step, so that the battery remains fully charged. This profile is optimal for most lead acid
batteries. For 24 V battery systems, the voltage (at 25°C) should be within the range of 28.4
to 30 V.
The battery backup is not like a traditional standard battery and charger. The system
implemented is in fact simpler as it splits the charger into two parts: a power supply and a
charger controller.
The main reason a traditional method cannot be implemented is because no off the shelf
charger exists that meets the wide temperature range of –40° to 60° and can withstand GE
type test requirements.
It is also important to capture the minimum and maximum voltages that the load can
withstand. The minimum turn ON voltage for the load Recloser Controller is 20VDC. The
battery should therefore supply power down to 20VDC and then cut the load off to prevent
deep discharge.
A Battery Management System (BMS) board is implemented to the BBS to optimize battery
life and provide useful feedback to the DGC. The BMS board will output the following to the
DGC:
1.
Battery Low warning (19.6 V)
2. Battery fuse blown.
Main function
The connections of the BBS components are shown in the BBS wiring diagram shown
below (Figure 8). Under normal running conditions, the main power supply feeds the DGCR
and the battery charger. When a power loss condition occurs, the battery supplies power
to the DGCR. Occasionally, the system checks the battery condition. The main functions
are presented in Figure 9: Battery Backup logic diagram.
MODES OF OPERATION
Run
5–19
S2 SYSTEM SETUP
In normal running condition, the power is fed from the unit labeled ‘POWER SUPPLY’,
contact output 1 is closed, and contact output 2 is open. So, the battery is connected to the
charger (unit labeled ‘CHARGER’) and its capacity is constantly being maintained at
optimum level. In addition, the DGCR CPU power input is constantly energized. Once the
unit is completely shut-off it cannot be powered by Battery only. An AC source must be
applied to turn the unit on.
Backup
The BBS switches to this mode, when the power is down. In Backup mode, terminals
labeled ‘BATTERY’ connect to terminals ‘DC LOAD’ inside the charger (unit labeled ‘ROGUE’)
allowing the battery to feed the DGCR. Contact output 1 is closed, and contact output 2 is
open.
Test
Battery test
In test mode, the battery is disconnected from the charger and connected to an 8 ohm
resistor for a certain time period that can be programmed in the BBS menu. During the
test, Contact output 1 is open and Contact output 2 is closed. The duration of the test can
be programmed. If the voltage stays above the contact input threshold (19.4 V) during the
test, the battery will be considered healthy. Otherwise, the test aborts and an alarm flag is
be set.
The sequence is initiated periodically. The time between two tests can be set. In addition,
pushing the button labeled ‘BATTERY TEST’ on the front panel, initiates the testing
sequence.
NOTE:
NOTE
If a power loss occurs during battery test, the DGCR power is supplied from the battery
through the diode D3. In addition, after the power loss (detected by low “AC power OK”
input), the battery test will abort within the output relay operate time.
Fuse test
The Battery fuse test is performed simultaneously with the battery test by checking the
state of Contact inputs 1 and 2. If both are detected high, the fuse is considered healthy. If
Contact input 2 is high but Contact input 1 is low, the fuse blown alarm will be set.
Battery alarm LED
This is a red LED located on the front panel. The LED light is off during normal operation.
The LED turns on in three cases as follows.
•
The battery test fails for a programmable number of times. Test failures have to be
consecutive in order to turn the LED on. (Steady)
•
The battery fuse test fails. (Steady)
•
The battery test is in progress (Flashing).
Reset
A manual or system reset command clears all battery related alarms and LED signals if the
alarm condition does not exist anymore.
5–20
•
The battery test mode is not affected by the reset command.
•
An additional reset command is provided. The path is: COMMANDS/BAT TEST CONT
RST. It has to be executed after the DEFECTIVE battery has been replaced with a new
one.

The Charger Controller has the following features:
10 Amp Capacity: The charger can facilitate a total of 10 amps to charge the battery
and power the load.
5–23
S2 SYSTEM SETUP
•
Temperature Compensation: The charger has an internal temperature sensor and
varies charging voltages accordingly.
•
3-stage Operation: The charger uses a 3 stage system to optimize lead acid battery
charging. (Refer to graph for typical charging pattern).
•
Low Voltage Disconnect: Optionally, you may connect the battery's load (up to 10
amps) to the charger. If the voltage drops to 20V, the load will be disconnected from
the battery after approximately one minute. The LVALERT signal (open drain) may be
used to gracefully shut down equipment during the one minute. The load is
reconnected when the battery is charged to approximately 24V, or when the recessed
reset button is pressed.
The controller terminals are listed below:

A microcontroller reads the battery and power input voltages, along with a set of internal
timers and other logic, and determines what the state of the switches (FETs) should be. The
two switches are controlled and activated independently, such that either one, both, or
neither switch can be activated at any given time.
Figure 5-10: BMS Charge Graph
The graph above shows an ideal charging cycle typically found after a lead acid battery
has discharged overnight. The red line (upper) indicates the battery terminal voltage and
the green line (lower) indicates the charging current supplied to the battery.
5–24
S2 SYSTEM SETUP
When the charger is first connected, or when the battery voltage drops below
approximately 2.15V per cell, the charger enters bulk (fast) mode, where it attempts to
bring the voltage to approximately 2.45V per cell. At this point, top-off mode is entered.
When the charger senses that the battery is no longer taking a charge, float mode is
entered where the voltage is lowered and maintained at approximately 2.3V per cell.
The current for the load will come from the solar/power input when available, and the
battery in that case will provide power filtering and smoothing to the load, while at the
same time maintaining a float/trickle charge from the power source. The battery
effectively acts as a large capacitor when connected in this manner
Battery safety
information
To prevent fire or chemical burns:
•
Do not attempt to recharge batteries after removal from the unit.
•
Do not disassemble, crush, or puncture the batteries.
•
Do not short the external contacts of the batteries.
•
Do not immerse the batteries in water.
•
Do not expose to temperatures higher than 80°C (176°F).
•
The batteries are recyclable. They contain lead and pose a hazard to the environment
and human health if not disposed of properly. Return the battery to a factory
authorized service center or refer to local codes for proper disposal requirements.
•
Do not open or mutilate batteries. They contain an electrolyte which is toxic and
harmful to the skin and eyes.
•
Replace batteries with the same number and type of batteries as originally installed.
To prevent personal injury from hazardous energy:
•
Remove watches, rings, or other metal objects.
•
Use tools with insulated handles.
•
Do not place tools or metal parts on top of batteries.
•
When removing and installing the new batteries, extreme care must be used not to
short metal chassis parts across the battery terminals and not to short the batteries
to each other. A battery can present a risk of electrical shock and high short circuit
current.
To prevent personal injury, prepare the area and observe all materials-handling

Phase IOC
The relay has one Instantaneous Overcurrent protection function Phase IOC. It consists of
three separate Instantaneous Overcurrent blocks; one per phase, with identical settings.
PATH: SETPOINTS > S3 CONFIGURATION > S3 SETPOINT GROUP 1/2/3 > PHASE IOC
PH IOC FUNCTION
Range: Disabled, Alarm, Latched Alarm, Trip
Default: Disabled
The selection of the Alarm, Latched Alarm, or Trip setting enables the Phase IOC function.
The output relay #1 operates when the Trip function is selected, and the Phase IOC
operates, providing no block command is active. The “ALARM” LED will not turn on if the
IOC operates when PH IOC FUNCTION is set to Trip. The “ALARM” LED flashes upon phase
IOC operation, and with the IOC function selected as Alarm, it will self-reset when the
operation clears. If Latched Alarm is selected, the “ALARM” LED flashes during IOC
operation, and stays “ON” after the operation clears, until the Reset command is
initiated. The output relay #1 will not operate if the Latched Alarm or Alarm function is
selected.
PH IOC PKP
Range: 0.05 to 8.00 in steps of 0.01 x CT
Default: 1.00 x CT
This setting sets the Instantaneous Overcurrent pickup level in per times CT. For
example, a PKP setting of 0.9 x CT with 300:5 CT translates into 270A primary current.
PH IOC PKP DELAY

Phase TOC
The relay has one Phase Time Overcurrent protection element per protection group. The
settings of this function are applied to each of the three phases to produce trip or pickup
per phase. The TOC pickup flag is asserted when the current on any phase is above the PKP
value. The TOC trip flag is asserted if the element stays picked up for the time defined by
the selected inverse curve and the magnitude of the current. The element drops from
pickup without operation, if the measured current drops below 97-98% of the pickup value,
before the time for operation is reached. The selection of Definite Time as a base time
delay of 0.1 s, multiplied by the selected TD multiplier. For example the operating time for
TOC set to Definite Time and a TDM set to 5 will result in 5*0.1 = 0.5 s.

the TOC operates when PH TOC FUNCTION is set to Trip. The “ALARM” LED flashes upon
phase TOC operation, with the TOC function selected as Alarm, and will self-reset, when
the operation clears. If TOC function is selected as a Latched Alarm, the “ALARM” LED
flashes during TOC operation, and stays “ON” after the operation clears until the reset

setting is selected.
PH TOC PKP
Range: 0.05 to 8.00 x CT in steps of 0.01 x CT
Default: 1.00 x CT
This setting sets the Time Overcurrent pickup level. For example, a PKP setting of 0.9 x CT
with 300:5 CT translates into a 270 A primary current.
PH TOC CURVE
Range: ANSI Extremely/Very/Moderately/Normally Inverse, Definite Time, IEC Curve A/B/C
and Short Inverse, IAC Extremely/Very/Inverse/Short, User Curve, FlexCurve A, FlexCurve B
Default: Extremely Inverse
This setting sets the shape of the selected TOC inverse curve. If none of the standard
curve shapes is appropriate, a custom User curve, or FlexCurve can be created. Refer to
the User curve and the FlexCurve setup for more detail on their configurations and
usages.
PH TOC TDM
Default: 1.00
This setting provides a selection for the Time Dial Multiplier by which the times from the
inverse curve are modified. For example if an ANSI Extremely Inverse curve is selected
with TDM = 2, and the fault current was 5 times greater than the PKP level, the operation
of the element will not occur before an elapsed time from pickup, of 495 ms.
PH TOC RESET TIME
Range: Instantaneous, Linear
Default: Instantaneous
The “instantaneous” reset method is intended for applications with other relays, such as
most static relays, which set the energy capacity directly to zero when the current falls
below the Reset threshold. The “linear” reset method can be used where the relay must
coordinate with electromechanical relays.

DESCRIPTION
The relay has a total of two phase, two neutral, and two ground/sensitive ground time
overcurrent elements. The programming of the time-current characteristics of these
elements is identical in all cases and will only be covered in this section. The required curve
is established by programming a Pickup Current, Curve Shape, Curve Multiplier, and Reset
Time. The Curve Shape can be either a standard shape or a user-defined shape
programmed with the FlexCurve™ feature.
Accurate coordination may require changing the time overcurrent characteristics of
particular elements under different conditions. For picking up a cold load, a different timecurrent characteristic can be produced by increasing the pickup current value. The
following setpoints are used to program the time-current characteristics.
•
<Element_Name> PICKUP: The pickup current is the threshold current at which the
time overcurrent element starts timing. There is no intentional ‘dead band’ when the
current is above the pickup level. However, accuracy is only guaranteed above a 1.5
per unit pickup level. The dropout threshold is 98% of the pickup threshold. Enter the
pickup current corresponding to 1 per unit on the time overcurrent curves as a
multiple of the source CT. For example, if 100: 5 CTs are used and a pickup of 90 amps
is required for the time overcurrent element, enter “0.9 x CT”.
•
<Element_Name> CURVE: Select the desired curve shape. If none of the standard
curve shapes is appropriate, a custom FlexCurve™ can be created by entering the trip
times at 80 different current values; see S2 SYSTEM SETUP > FLEXCURVE A. Curve
formulas are given for use with computer based coordination programs. Calculated
trip time values are only valid for I / Ipu > 1. Select the appropriate curve shape and
multiplier, thus matching the appropriate curve with the protection requirements. The
available curves are shown in the table below.

•
<Element_Name> MULTIPLIER: A multiplier setpoint allows shifting of the selected
base curve in the vertical time direction. Unlike the electromechanical time dial
equivalent, trip times are directly proportional to the value of the time multiplier
setpoint. For example, all trip times for a multiplier of 10 are 10 times the multiplier 1
or base curve values.
When Timed Over-Current is programmed with Definite time, the operating time is
obtained after multiplication of the selected Multiplier (TDM) by a 0.1 s base line. For
example, selection of TDM = 5 would lead to a 0.5 s operating time.
•
5–34
<Element_Name> RESET: Time overcurrent tripping time calculations are made with
an internal ‘energy capacity’ memory variable. When this variable indicates that the
energy capacity has reached 100%, a time overcurrent trip is generated. If less than
100% is accumulated in this variable and the current falls below the dropout threshold
of 97 to 99% of the pickup value, the variable must be reduced. Two methods of this
resetting operation are available, Instantaneous and Linear. The Instantaneous
selection is intended for applications with other relays, such as most static units,
which set the energy capacity directly to zero when the current falls below the reset
threshold. The Linear selection can be used where the relay must coordinate with
electromechanical units. With this setpoint, the energy capacity variable is
decremented according to the following equation.

TOC CURVE CHARACTERISTICS
ANSI Curves
The ANSI time overcurrent curve shapes conform to industry standards and the ANSI
C37.90 curve classifications for extremely, very, normally, and moderately inverse. The
ANSI curves are derived from the following formula:

IEC Curves
For European applications, the relay offers the four standard curves defined in IEC 255-4
and British standard BS142. These are defined as IEC Curve A, IEC Curve B, IEC Curve C, and
Short Inverse. The formulae for these curves are:
where: T = trip time (seconds), M = multiplier setpoint, I = input current, Ipu = pickup current
setpoint, K, E = constants.

USER Curves
The relay provides a selection of user definable curve shapes used by the time overcurrent
protection. The User curve is programmed by selecting the proper parameters in the
formula:
A, P, Q, B, K - selectable curve parameters within the ranges from the table: D is the Time
Dial Multiplier.
User Curve can be used on multiple elements only if the time dial multiplier is the same for
each element.
V = I/IPICKUP (TOC setting) is the ratio between the measured current and the pickup setting.
The maximum trip time for the User Curve is limited to 65.535 seconds. The User Curve can
be used for one protection situation only.

Flexcurves
Prospective FlexCurves™ can be configured from a selection of standard curves to provide
the best approximate fit, then specific data points can be edited afterwards. Click the
Initialize button to populate the pickup values with the points from the curve specified by
the "Select Curve" setting and the "Multiply" value. These values can then be edited to
create a custom curve. Click on the Clear FlexCurve Data button to reset all pickup values
to zero.
Curve data can be imported from CSV (comma-separated values) files by clicking on the

CSV is a delimited data format with fields separated by the comma character and records
separated by new lines. Refer to IETF RFC 4180 for additional details.
The curve shapes for the two FlexCurves are derived from the following equations.
In the above equations, Toperate represents the operate time in seconds, TDM represents
the multiplier setting, I represents the input current, Ipickup represents the value of the
pickup current setting, Tflex represents the FlexCurve™ time in seconds.

S3 CONFIGURATION
Figure 5-15: Flexcurve™ configuration settings
The following settings are available for each custom Flexcurve™.
Select Curve
Range: ANSI Moderately Inverse, ANSI Very Inverse, ANSI Extremely Inverse, IEEE Normally
Inverse, IEC Curve A, IEC Curve B, IEC Curve C, IEC Short Inverse, IAC Extreme Inv, IAC Very
Inverse, IAC Inverse, IAC Short Inverse, User Curve, FlexCurve B (Note: For FlexCurve A, you
can select FlexCurve B as the setpoint, and vice versa for FlexCurve B.)
Default: Extremely Inverse
This setting specifies a curve to use as a base for a custom FlexCurve™. Must be used
before Initialization is implemented (see Initialization below).
Multiply
Default: 1.00
This setting provides selection for Time Dial Multiplier by which the times from the
inverse curve are modified. For example if an ANSI Extremely Inverse curve is selected
with TDM = 2, and the fault current was 5 times bigger than the PKP level, the operation
of the element will not occur before a time elapse of 495 ms from pickup.
Initialization
Used after specifying a curve to use as a base for a custom FlexCurve™ (see Select
Curve and Multiply above). When the Initialize FlexCurve button is clicked, the pickup
settings will be populated with values specified by the curve selected in this setting.
5–40
S3 CONFIGURATION
1.03 × Pickup, ..., 20.00 × Pickup
Range: 0 to 65535 ms in steps of 1
Default: 0 ms
These settings specify the time to operate at the following pickup levels 1.03 to 20.00.
This data is converted into a continuous curve by linear interpolation between data
points. To enter a custom FlexCurve™, enter the operate time for each selected pickup
point.
NOTE:
NOTE
Each FlexCurve can be configured to provide inverse time characteristic to more than one
Time Overcurrent Element. However, for computation of the curve operating times, one
must take into account the setting of the Time Delay Multiplier from the FlexCurve menu,
and the Time Delay Multiplier setting from TOC menu. The true TDM applied to the TOC
element when FlexCurve is selected is the result from the multiplication of both TDM
settings. For example, for FlexCurve Multiplier = 5, and Phase TOC Multiplier = 2, the total
Time Dial Multiplier will be equal to 10. To avoid confusion, it is suggested to keep the
multiplier from the TOC menu equal to 1, and change only the multiplier from the selected
FlexCurve. This way, one can see from the FlexCurve setup, the curve operating times as
related to the multiples of pickup.
Neutral overcurrent
The relay has one Neutral Instantaneous Overcurrent protection function. The settings of
this function are applied to the calculated neutral current for pickup and trip flags. The
Neutral IOC pickup flag is asserted when the neutral current is above the PKP value. The
Neutral IOC operate flag is asserted if the element stays picked up for the time defined by
the Neutral IOC Delay setting. If the pickup time delay is set to 0.00 seconds, the pickup and
operate flags will be asserted at the same time. The element drops from pickup without
operation, if the neutral current drops below 97-98% of the pickup value.

Phase undervoltage
For voltage sensitive loads, such as induction motors, a drop in voltage will result in an
increase in the drawn current, which may cause dangerous overheating in the motor. The
undervoltage protection feature can be used to either cause a trip or generate an alarm
when the voltage drops below a specified voltage setting for a specified time delay.

The selection of the Latched Alarm, Alarm, or Trip setting enables the Phase UV function
if there is no active block command. The output relay #1 will operate if the function is
selected as a Trip, and the phase voltages from the selected “PH UV PHASES”
combination are below the PH UV PKP setting for a time greater than the selected PHASE
UV DELAY time. The “ALARM” LED will not turn on if the phase UV function is set to Trip.
The “ALARM” LED flashes upon the UV operating condition, with the phase UV selected
as Alarm, and will self-reset, when this operating condition clears. If Latched Alarm is
selected as a phase UV function, the “ALARM” LED will flash during the UV condition and
will stay “ON” after the condition clears, until the reset command is initiated. The output
relay #1 will not operate if the Latched Alarm or Alarm setting is selected.
PH UV PKP
Default: 0.75 x VT
This setting defines the phase UV pickup level, and it is usually set to a level, below which
the drawn current from voltage sensitive loads, such as induction motors may cause
dangerous motor overheating conditions.
PH UV CURVE
Range: Definite Time, Inverse Time
Default: Inverse Time
This setting selects the type of inverse time curve, to define the time of undervoltage
operation based on selected UV time delay, and the actual undervoltage condition with
respect to selected UV pickup.

Power loss
The Power Loss protection function is used to detect a power loss condition in each phase
of the power distribution line. After opening the upstream breaker, the DGC has to confirm
that the voltage and current level of the line are below a minimum threshold on the source
side. If the recloser is supplied from the load side, the same logic applies but the voltages
are read from the load side VTs.
The power loss flags generated by this element are used by the Battery Backup System
and they can also be transferred to a higher level control system e.g. SCADA.

MIN PH CURR PICKUP
Range: 0.01 to 0.40xCT in steps of 0.01xCT, OFF
Default: 0.03
This setting is used to detect the circuit breaker open condition. When a phase current
falls below this threshold and at the same time the voltage of the same phase falls below
its minimum value, the power loss condition of this phase is declared after the power
loss delay expires.
MIN PH VOLT PICKUP
Range: 0.05 to 0.40xVT in steps of 0.01xVT, OFF

S3 CONFIGURATION
RCR Wearing monitor
The DGCR provides counters for counting the recloser OPEN and CLOSE actions. Every new
OPEN action increments the content of the Flexlogic variable RECLOSER OPEN COUNT.
Equally, every new CLOSE action increments the content of the Flexlogic variable
RECLOSER CLOSE COUNT. Both variables are located in MAINTENANCE / M3 COUNTERS.
The user can select the limit for each action separately. When a limit has been reached, a
corresponding message is produced.
The logic diagram of the Recloser Action Counter is depicted in the figure below.
The DGCR is provided with an Arcing Current Counter that calculates the energy of the arc
created for every recloser open action. The calculation is performed for each phase and it
is based on the instantaneous value of the KI2t being integrated for the duration of the
recloser open action. Furthermore, the controller adds up the arc energy of every new
recloser open action, creating an accumulated count of this quantity for a long period of
time. The accumulated arcing energy of phase A is saved in the Flexlogic variable KI2t RCR
COUNT PH A, as is the accumulated arcing energy of phases B and C. The controller
provides for setting the limit for arcing energy and if any of the phases’ arcing energy value
exceeds this limit, the alarm message is triggered. Usually, the recloser manufacturer
provides the maximum KI2t value and when this value is reached, the recloser has to be
repaired. This makes the Arcing Current function a very useful maintenance tool.
The logic diagram of the Arcing Current Counter is depicted in the figure below.

ACT CNTR FUNCT
Default: Disabled
This setting enables the functionality of the Recloser Action Counter. It has two separate
parts: one for counting open actions, and another for counting close actions of the
recloser. When enabled, every open or close action of the recloser results in
incrementing of the open or close count respectively.
OPEN CNTER LIMIT
Default: 9999
Range: 1 to 9999 Steps 1
This is the maximum number of openings allowed for the controlled recloser. When this
value is exceeded, the message OP CNT LIM REACHED appears to signal this issue. Once
the message is activated, it can be removed by resetting the open counter. The path of
the reset command is: MAINTENANCE / M3 RESET COUNTERS / RESET OPEN COUNT.
When the limit of 9999 is reached the Open Counter starts from zero.
CLOSE CNTER LIMIT
Default: 9999
This is the maximum number of closings allowed for the controlled recloser. When this

in OPEN RESET TIME, if this time is shorter than the total of open reaction time + SEAL-IN
TIME.
BLOCK OPEN CMD
Range: Off, Any input from the list of inputs
Default: Off
This setting defines a block to the open recloser command. When the selected input is
asserted, the output relay “RLY 1 OPEN” will be blocked.
CLOSE RESET TIME
Default: 3.00 s
Upon issuing a CLOSE command, the output relay “RLY 2 CLOSE” will energize. Then, after
a period of time that depends on the recloser design (recloser close reaction time), the
recloser will close. When the recloser is detected closed, a timer will start running and
after the time set in S4 / RLY 2 CONTROL / SEAL-IN TIME is elapsed, the output relay “RLY
2 CLOSE” will de-energize. However, “RLY 2 CLOSE” will de-energize after the time set in
CLOSE RESET TIME, if this time is shorter than the total of close reaction time + SEAL-IN
TIME.
BLOCK CLOSE CMD

Change settings group
The DGCR has three identical settings groups - Groups 1, 2 , and 3 - for all DGCR monitoring
elements. Switching between these three groups is available either automatically by
assigning an input (contact, virtual, remote, flexlogic element), or manually through
communications.
Group 1 is the default setting group. The device can automatically switch from Group 1
DGCR elements to the other group elements, and vice versa, by setting up the switching
conditions under “Change Settings Group”. Under some application conditions, it may be
undesirable to change settings groups. In such cases, the user can set a condition under
“BLK GROUP CHANGE”, where if asserted, the active settings group will stay active, even if
the input configured to switch to the other settings group is asserted. For example if the
active group was group 1 at any given time, and the input configured under “BLK GROUP
CHANGE” is asserted, the relay will maintain settings group 1, even if the input “SET GROUP
2 (3) ACTIVE” is asserted. Visa versa, if the “BLK GROUP CHANGE” input is asserted, the relay
will not switch from group 2/3 to group 1, even if the input under “SET GROUP 2 (3) ACTIVE”
is de-asserted.
The device will default to settings group 1, if both the input “SET GROUP 2 (3) ACTIVE” and
the blocking input “BLK GROUP CHANGE” are de-asserted.
Table group 3 of settings has a higher priority than the rest of settings groups. That means,
if both “SET GROUP 2 ACTIVE” and “SET GROUP 3 ACTIVE” signals are maintained asserted
at the same time, the DGCR will change to the table 3 of settings.
The logic functionality takes into account this feature.
PATH: S4 CONTROLS > CHANGE SETP GROUP

This setting selects an input, used to change to Settings Group 2, when asserted. If no
group change supervision is selected, the Settings Group 2 will stay active as long as the
“SET GROUP 2 ACTIVE” input is asserted, and will revert to group 1 when this input is deasserted.
SET GROUP 3 ACTIVE

Default: Off
This setting selects an input, used to change to Settings Group 3, when asserted. If no
group change supervision is selected, the Settings Group 3 will stay active as long as the
“SET GROUP 3 ACTIVE” input is asserted, and will revert to the default group, when this
input is de-asserted.

Cold load pickup
The DGCR can be programmed to block the instantaneous over-current elements, and
raise the pickup level of the time over-current elements, when a cold load condition is
detected. The cold load condition is detected during closing of the breaker on a feeder that
has been de-energized for a long time. The feeder inrush current and the motor
accelerating current during breaker closing may be above some over-current protection
settings. The diagram shows the slow decaying of the cold load current starting at about
500% of the nominal current at the time of breaker closing, decaying down to 300% after 1
second, 200% after 2 seconds, and 150% after 3 seconds.

The relay detects Cold Load condition (Cold Load Pickup armed), if the currents on all three
phases drop below 3% of the CT nominal rating for the period of time greater, than the
Outage Time Before Cold Load setting. The Cold Load condition can be immediately
initiated (Outage Time Before Cold Load timer bypassed), by asserting a contact input
selected for External CLP Initiate.
The second timer Cold Load Pickup Block is used to specify the time of blocking the
instantaneous over-current elements, and the time of raised pickup levels of the time overcurrent elements, after breaker closing. The timer starts when at least one of the three
phase currents is above 10% of CT nominal. Upon timer expiration, the settings return to
normal.

Autorecloser
The automatic 3-pole recloser is intended for use on three-pole recloser applications. Up to
four reclosing “shots” can be programmed with independent set of protection elements for
initiation, and individual dead time prior to each subsequent shot. A typical example would
be to select instantaneous overcurrent protections for the AR initiation, and selection of
time overcurrent protections to permit (no blocking) operation after the first reclose. This
would provide longer time before the recloser opens, and allow the fuses to burn off, if the
fault is still present.
PATH: SETPOINTS > S4 CONTROLS > AUTORECLOSURE > AR SETUP
NUMBER OF SHOTS
Range: 1..4 in steps of 1
Default: 1
The aximum number of reclosers that are attempted before a lockout.
DEAD TIME SHOT 1/2/3/4
Range: 0.1..0.600.0 s in steps of 0.01 s
Default: 1/2/3/4
This setting specifies the dead time delay before each reclosure. There are four time
delay settings to be configured and used to time out before the first, second, third or
fourth reclosure.
RESET LOCKOUT TIME
Default: 10 s
This setting specifies the reset lockout time. Upon recloser close and if autoreclosing
automatic lockout reset (AR AUTO LO RESET) is set ON, the timer times out and resets the
“AR LOCKOUT” state.
INCOMP SEQ TIME
Default: 5 s
This timer is used to set the maximum time interval allowed for a single reclosure shot.
The timer starts timing out for both situations: upon AR initiates to open the recloser,
where the recloser doesn’t open, or whenever a recloser reclose command is issued,
where the recloser doesn’t close. Upon incomplete sequence time expiry, the AR goes
into lockout mode.
AR RESET TIME
Default: 5 s
This time is used to reset the AR into AR ready mode after successful reclosure. If no
recloser tripping occurs within the reset time, the AR shot counter is reset.
BLOCK AR
Range: Off, Contact Input 1-30, Virtual Output 1-32, Virtual Input 1-32, Remote Input 1-x

Autoreclosure Logic
Diagram
S4 CONTROLS
The Automatic Reclosure function is designed to perform up to four recloser
autoreclosings, with a configurable dead time before each of the reclosing shot. Upon AR
function enabled selecting Auto mode, and recloser status “closed”, the AR is set into “AR
Ready” state. If an intermittent feeder fault occurs such as overhead conductor touching
tree branch, one or more of the overcurrent protections enabled under AR initiate menu,
will operate and issue recloser trip command. If the recloser opens, the dead time
configured under the first AR shot will start timing out. After this time expires, the AR
scheme will produce the first recloser reclosing shot. Upon recloser close and no fault
conditions, the overcurrent elements permitted to operate on the first AR shot will not
operate, and the reclosing is declared successful. The remaining part of the configured AR
sequence will not be executed. The AR Reset time will start timing out, where upon time
expiry resets the AR counter. The AR sequence is reset with AR function into “AR Ready”
state.
Now, if the fault is permanent, the configured AR sequence will be executed in full, where
the recloser opens after the last reclosing shot and the AR function goes into lockout.
The reclosure scheme passes through the following states during operation:
AR NOT READY LOCKOUT: When in this state, the AR is blocked. The AR LOCKOUT occurs if
any of the following conditions is present:
•The maximum shot number was reached and new Reclose Initiation (RI) event occurs.
•The incomplete sequence AR INCOM SEQ TIME timer times out while waiting for the
Recloser to close.
•The Reclose Initiation (RI) event occurs and recloser status is CLOSED and AR INCOM
SEQ TIME timer times out.
•The Reclose Initiation (RI) event occurs and AR INITIATE (external or by overcurrent
element) input stays on (or new RI occurs) and AR INCOM SEQ TIME timer times out.
•If any AR DEAD TIME SHOT timer starts to time out and the recloser status changes to
CLOSED.
•If any AR DEAD TIME SHOT timer starts to time out and reclose Initiation (RI) input
occurs.
If the recloser status changes to OPEN and new reclose Initiation (IR) happens.The
recloser is latched in LOCKOUT state until:
•The recloser is closed and the variable “autoreclosing automatic lockout reset” (AR
AUTO LO RESET) is set ON and the reset lockout time expires.
•The autoreclosing remote lockout reset command is received by contact input,
virtual input, virtual output or remote input (remote mode).
•Faceplate pushbutton AS LOCKOUT RESET is pushed (local mode).
AR READY: To reach this state the RST LO TIME timer times out from LOCKOUT state if AR
AUTO LO RESET is enabled, or autoreclosing LOCKOUT state is manually reset or the AR
RESET TIME timer times out from WAIT RST TIME state. In this state the autorecloser is
waiting for reclose Initiation (RI) event to start the reclosure process.
AR IN PROGRESS: To reach this state the autoreclosing has to be in AR READY state and
reclose Initiation (RI) event starts the reclosure process until the AR RST TIME timer times
out (or the AR BLOCK INPUT is set) and the autorecloser goes into AR READY state waiting
for a new AR execution.
WAIT FOR 52 OPEN: Once a reclose Initiation (RI) event occurs the autorecloser is waiting
for recloser status OPEN or otherwise the AR INCOM SEQ TIME timer will time out. If the AR
INCOM SEQ TIME expires, the autorecloser will go into LOCKOUT state. However if the
recloser opens, the AR scheme will start the configured DEAD TIME timer, and will be into
WAIT DEAD TIME state.
WAIT DEAD TIME: In this state the autorecloser is waiting for the relevant AR DEAD TIME
SHOT timer to time out. If during this time out the recloser status changes to CLOSE, a
reclose Initiation (RI) occurs the autorecloser process ends in a LOCKOUT state. If not, the
WAIT FOR 52 CLOSE state is reached.
5–71
S4 CONTROLS
WAIT FOR 52 CLOSE: In this state upon reclosing command, the autorecloser is waiting for
the recloser to CLOSE. If the AR INCOM SEQ TIME timer times out or a new reclose Initiation
(RI) occurs and it’s the last shot then the autorecloser ends in a LOCKOUT state. If a new
reclose Initiation (RI) occurs and it is not the last from the programmed sequence, the
autorecloser goes into the WAIT FOR 52 OPEN status.
WAIT RESET TIME: In this state, when the AR RST TIME timer times out the number of shots
is reset and the autorecloser goes into AR READY state waiting for a new AR execution.
If a new reclose (RI) different from the last shot occurs the autorecloser goes into the WAIT
FOR 52 OPEN status for the next shot.
Reclose Initiation (RI) is produced by a trip with the relevant permission enabled or by AR

FlexLogic™
The DGCR FlexLogic™ system, defines operators, and lists of operands. In essence, all the
necessary information for custom built logic. The FlexLogic tool is accessible from the
EnerVista DGCR Setup program under the SETTINGS/ FLEXLOGIC menu
All DGCR digital signal states are represented by FlexLogic™ operands. Each operand is in
one of two states: on (asserted, logic 1, or set), or off (de-asserted, logic 0, or reset). There is
a FlexLogic™ operand for each contact input, contact output, communications command,
control panel command, element trip, and element alarm, as well as many others.
A list of FlexLogic™ operands and operators are sequentially processed once every 4.17
ms or 5 ms, depending on the power system frequency (60 Hz or 50 Hz). When list
processing encounters an operand, the value of that operand is placed in a first in - first
out stack. When list processing encounters a calculation operator, the number of values
required for the calculation are removed from the stack, and the result of the operation is
placed back on the stack. The operators are logic gates (for example, AND, OR, NOT),
timers, latches, one-shots, and assignments. Assignment operators assign the value
calculated by the preceding operators to a special class of operands called virtual outputs.
Like any other operand, a virtual output can be used as an input to any operator –
feedback to achieve seal-in is allowed. When list processing encounters an end operator,
processing is stopped until the next processing cycle, at which time it restarts at the top of
the list.
Each contact output has a setting to specify the operand that drives the output. Any
operand may be selected – selection of a virtual output is the means by which FlexLogic™
directly controls external equipment such as the motor contactors.
The operators used in FlexLogic™ conform to the following rules:
•
512 lines for bulding logic are available in the FlexLogic tool. All lines are executed
every 1 / 4 power system cycle (4.17 ms. or 5 ms).
•
A virtual output may only be assigned once within the FlexLogic environment. An
unassigned virtual output will have a value of off.
•
A maximum of thirty (32) general purpose timers (timers 1 through 32) are available for
configuration. Each timer may only be used once within the FlexLogic environment.
•
A maximum of thirty (30) one-shots is allowed.
•
A maximum of 16 latches is supported.
The operators available in FlexLogic™ are shown below:

NOTE:
NOTE
Default: Off
The auxiliary relay state is equal to the value of the selected function variable.
OUTPUT TYPE
Range: Self-Reset, Latched
Default: Self-Reset
Each auxiliary relay can be selected as either Self-Reset, or Latched. If the Self-Reset
type is selected, the output relay is energized as long as the element is in operating
mode and will reset when the element drops out. If the Latched type is selected, the
output relay stays energized, after the element dropout, and will be de-energized upon
the reset command.
If an auxiliary output is only required while the activating condition is present, select
Self-Reset. Once an activating condition disappears, the auxiliary relay returns to the
non-active state and the associated message automatically clears. To ensure all
auxiliary function conditions are acknowledged, select Latched.
OPERATION
Range: Failsafe, Non-Failsafe
Default: Non-Failsafe
The auxiliary relay state is equal to the value of the selected function variable.When
Failsafe operation is selected, the auxiliary relay is energized or de-energized (state
change) depending on the following conditions:
1. The auxiliary relay is de-energized, if the relay is not IN SERVICE or the control power is
not applied to the relay.
2. The auxiliary relay is energized when the control power is applied to the relay and the
relay is IN SERVICE mode.
3. The auxiliary relay stays de-energized, when the control power is applied, upon major
self-test failure during relay boot up.
4. The auxiliary relay changes state from energized to de-energized if the DGCR
experiences any major self-test failure.
Virtual inputs
There are 32 Virtual Inputs that can be individually programmed to respond to Input
commands entered via the relay keypad, or by using communication protocols.
Virtual Input programming begins with enabling the Virtual Input function and selecting
the Virtual Input Type - Self-Reset or Latched - under SETTINGS > S5 INPUTS/OUTPUTS.
Next, under SETTINGS > S4 CONTROLS > S4 VIRTUAL INPUTS, the user assigns either an On
or an Off command to the Virtual Input enabled earlier.
Referring to the Virtual Inputs logic diagram below, a Virtual Input type can be selected to
be either Self-Reset, or Latched. When Self-Reset is selected, and the command On is
executed, the virtual input is evaluated as a pulse at rate of one protection pass. When the
Latched type is selected, the On state of the Virtual Input will be latched.
SETTINGS > S5 INPUTS/OUTPUTS > VIRTUAL INPUTS
VI x NAME
Range: 18 Characters
Default: Virtual IN x

Commands
The DGCR OPEN/CLOSE commands can be used in three different ways:
•
OPEN and CLOSE commands from the DGC faceplate pushbuttons or the DGC menu.
This method of control is active in Local / Manual mode, providing that the
DGCR control is not set to OFF and no other blocks or switching inhibits are applied.
•
Remote OPEN and CLOSE control upon energizing of assigned inputs under SETTINGS/
CONTROLS/REMOTE CONTROL.
This method of control will be active, in Remote / Manual and Remote / Auto mode,
providing the DGC–R control is not set to OFF and no other blocks or switching inhibits
are applied.
•

7–2
CHAPTER 7: COMMANDS
OPEN and CLOSE commands over DNP addressing, using radio
The OPEN or CLOSE command can be initiated from a SCADA or an IED using radio
communication. The controlling device maps an OPEN or CLOSE command to its binary
outputs and transmits them via radio communication to the controller. Upon receipt the
DGCR controller executes the appropriate action. The DGCR controller executes the
received commands, if the controller is not in OFF mode and the selected control mode is
set to “Remote” (the Remote LED is lit). The remote OPEN and CLOSE commands via radio,
are blocked if the “Local” control mode is selected (the “Local” LED is lit).
