WaterWorks 2000 Features
“State of the Art Controls”
GRAVER WaterWorks® 2000 SYSTEM - INCLUDED SOFTWARE FEATURES
ALARMS - An alarm window is visible at all times that announces
current alarms and their status. A separate window, Alarm Summary,
shows a summary of current alarms and their conditions. Another
window, Alarm History, shows a history of alarms and logs this data to
the hard disk where it can be retrieved and viewed at a later time. This option enables trouble
shooting of events by viewing operator actions and equipment status in a historical format.
ANALOG/DIGITAL READOUTS - Analog values are represented both in traditional
bar graph form and in precise digital readouts. This approach makes it simple to
determine if a reading is within range by its relative position in the bar graph, while
providing a means to interpolate the actual readings accurately.
COLOR BLIND FEATURES - A large number of our population has difficulty
distinguishing certain colors. The GRAVER WaterWorks System software
contains graphics that address this condition. Changes in conditions are indicated
by a combination of pointers, bars, and text.
USER FRIENDLY MOVEMENT - Movement from screen to
screen is made simple and logical. It is accomplished by activating
the "hot key" at the end of a line (pipe). Activating a "hot key"
takes the operator to the continuation of a line on a different screen.

VALVE & PUMP DISPLAYS - In all displays, the valve and pump colors reflect the
actual state of the devices. As is standard in the water treatment industry, red
(dangerous) reflects running equipment or open valves while green (safe) reflects
stopped equipment or closed valves. Typically, pumps are controlled by a small
pop-up window that gives the operator three modes of control: Hand (manual on),
Auto (controlled by PLC), and Off (Manual stop). Valves are controlled by means of
graphical icon pushbuttons.
PUMP TRIP REACTION- If a pump fails to operate, the operator is immediately
notified and a back-up pump (if one is provided) is automatically brought on-line.
The GRAVER WaterWorks System offers either the "alternator" or "lead-lag"
style of back-up, whichever meets the needs of your specific plant.
FAIL-SAFE OPERATION OF ANALOG INPUTS - If an analog input card fails, "safe" pre-set
values are loaded into the registers to force the system to a known state.
GRAPHICAL ICON BUTTONS - A picture is worth a thousand words. Graphical icon buttons
allow operators to quickly access commonly used screens such as analog displays, historical
trending, reports, main menu, tagouts, sequencer status, etc.
PREVIOUS SCREEN HOT KEY - A “hot” key on the keyboard allows the operator to toggle to the
previous screen and back again for quick viewing of information or equipment status on other
screens.

SEQUENCER
STATUS/CONTROL
SCREENS
®
GRAVER WaterWorks makes use of a sequencer
status/control screen and unique PLC algorithms that
work together to give you complete control of equipment
sequences. This features gives you both flexibility and
repeatability in one package. It allows you to stop the
sequence, advance it, reverse it, extend the time for
timed steps, and customize the step duration.
COMMUNICATIONS MONITORING - Depending on the capabilities of the PLC, it is standard in a
GRAVER WaterWorks® System to constantly monitor the status of communications between the
CRT and the PLC. If a loss of communications should occur, a pop-up window appears
informing the operator that communications have been lost with the PLC.
FAULT TOLERANCE & REDUNDANCY - This option minimizes the effect of a single point failure
of control equipment. This is accomplished by carefully engineering the system to insure critical
equipment is properly isolated.
OPEN ARCHITECTURE - Open architecture provides flexibility to initiate changes, add additional
equipment/modules, interface with most DCS systems, and network resources and data with
other computers. Operator stations can be remotely located. They can also be configured in
three ways: Runtime/Development (allows trained personnel to make changes to system and
operate system), Runtime (allows operation only of system), and View (allows the status of
equipment to be viewed only and does not allow operation).
CUSTOM MODULES AND FEATURES - All GRAVER WaterWorks® 2000 Systems can be
tailored to suit your custom needs. We are open to all your requests and willing to discuss your
needs up front. This ensures that our final product will be exactly what you want.

I.F -- GRAVER WaterWorks 2000 SYSTEM OPTIONAL SOFTWARE MODULES
SECURITY - Our security system allows only trained and approved personnel
to operate the system. With the security system installed, users must log on
with a user name and password. This feature allows 10,000 levels of security
allowing or disallowing access to certain controls and displays.
VALVE CONTROL, STATUS, & PRE-LOADS - Graphical representation
of valves allow direct manual control of valves and monitoring of their
status from the CRT in both manual and automatic modes. A “Pre-Load”
indicator allows operators to define the position of the valves prior to
placing the system into manual. This accomplishes a “bumpless” transfer
into the manual position.
VALVE DISCORDANCE MONITORING - If limit switches are available or added, a
discordance indicator can display valve discordance alarms generated by the GRAVER
WaterWorks® PLC control algorithms. The GRAVER WaterWorks System 2000
program compares the actual versus the pre-set position in a sequence or operation. An
operator is notified immediately if a valve operates outside the pre-set limits.
HISTORICAL DATA TRACKING, LOGGING AND REPORT GENERATION - The GRAVER
WaterWorks® 2000 System allows real-time viewing of analog
historical data. The analog data is logged to the hard disk where it
can be retrieved and viewed at a later time. The report generation
module enables you to print custom reports of this logged data as
well as export the data for manipulation in popular spreadsheet
programs. This feature gives you insight into dips and spikes in
your process and helps you troubleshoot past occurrences.

PREDICTIVE MAINTENANCE ASSISTANCE - Most maintenance programs are based upon
time, rather than usage.
Frequently, system components are maintained or rebuilt at
pre-determined time intervals. The GRAVER WaterWorks 2000 System takes maintenance into
the next generation - it measures the usage of a particular component (i.e., the actual number of
times a valve strokes or the total number of hours a pump has operated). Using this information,
a plant can schedule maintenance in a routine manner thereby maximizing the benefit of its
maintenance dollars.
COMMUNICATIONS - This feature allows the plant to communicate, via a modem, with our
Cranford, NJ facility. This provides the plant with a team of experienced engineers, chemists, and
other water treatment professionals, only a telephone call away. If desired, we can also
troubleshoot your system on-line to provide you with immediate changes. Changes can also be
transmitted via the World-Wide-Web and our modern E-mail system can provide you with
documentation and other items within minutes.
VALVE AND MOTOR TAGOUT - This module, while not intended as a safety
lockout, enables the operator to disable equipment on the CRT display and
visually identify equipment that has been physically tagged out. This feature
works in conjunction with PLC programmed interlocks which also disables
equipment from operation. When used in conjunction with the correct physical
hardware, an effective safety program for equipment maintenance can be
established.
PLC DIAGNOSTICS - PLC diagnostics screens are available to remote view the status of your
Programmable Logic Controller. You can view major and minor faults, clear faults, and determine
if PLC is in Run, Remote, or Program mode (Check with Graver for compatibility with your desired
PLC system.)
ANALOG ALARM INDICATION - In the GRAVER WaterWorks® 2000 System,
analog alarms are generated within the PLC. These alarms can trigger analog
displays to indicate when an analog value exceeds programmed parameters
such as High-High, High, Low, or Low-Low setpoints.

EQUIPMENT TAGS SHOW/HIDE - In the standard GRAVER WaterWorks® 2000 System,
equipment tags are displayed by the graphical controls of the equipment. Depending upon the
system tagging format , some customers request this feature so that they will have the ability to
hide or show part or all of the tag text. This feature helps avoid screen clutter for operators who
are intimately familiar with their system.
ALARM HELP/ AUTOMATIC RESPONSE PROCEDURES - Why
try and keep manuals on hand when you have a computer right in
front of you. The GRAVER WaterWorks® 2000 System features an
on-line help feature that is custom made for your plant. Using the
standard Windows® Help file format, we will compile a help file that
is automatically started when an operator clicks the mouse on an
active alarm. The help file displays information or response
procedures that you provide related to the alarm.
LABORATORY DATA ENTRY- This module allows direct entry of values into the PLC. This
module is useful for systems that use GRAVER WaterWorks® 2000 to automatically calculate
program parameters such as run lengths, chemicals to be added, etc.
GRAVER SMART SYSTEMS - Currently the GRAVER Smart Reactivator® (for clarifiers) is the
only smart system available. It makes use of the direct lab entry, feedback from specialized
instruments and compiles the data in a popular spreadsheet program via proprietary Graver
control algorithms to constantly and dynamically adjust operating parameters for an ideal water
quality output.
TECHNICAL SUPPORT - Graver also provides support for our GRAVER WaterWorks® 2000
System. While we will ensure that your system is complete and to your satisfaction, we know that
changes are inevitable. Because of the Open Architecture of the GRAVER WaterWorks® 2000
System, we can give you the ability to make the changes yourself. Of course, who better is
qualified to assist you with your changes than the company who originally designed the system.
Technical support options are available on a monthly basis.
