DESCRIPTION
The Avtron Model XR125 SMARTSafeTM encoder is a heavy duty
encoder for hazardous locations (also known as tachometer or rotary
pulse generator), allowing operation down to zero RPM. It provides
a specific number of electrical Pulses Per Revolution (PPR) that are
proportional to a shaft’s revolution. The XR125 SMARTSafe encoder
is a bearingless, couplingless, modular design, providing unequaled
reliability and mechanical performance.
CAUTION
The XR125 is designed for use in hazardous applications
which require protection from gas or dust ignition for
safe operation. Proper selection, wiring and installation
procedures are essential to ensuring safe conditions.
The XR125 fits AC and DC motors with an 12.5” C Face. Both end-ofshaft and through shaft mountings are accommodated. XR125 may
also be installed as an open modular unit without the C Face.
The XR125 Encoder consists of three or four parts: a rotor, a stator
housing, and one or two removable sensor modules. These precision
machined parts mount to the accessory end of a motor that
conforms to NEMA MG1 for Type FC Face Mounting. See Mechanical
Specifications. No gapping, adjustment, or shimming is required!
(If the XR125 is installed as an open rotor and sensor only system
without a C face, then manual gapping of the sensor is needed.)
The XR125 utilizes magnetoresistive sensors. This proven technology
is ideal for rugged environments since it is immune to many
contaminants that cause optical encoders to fail. All of the XR125
electronics are potted, providing full protection against liquids.
The outputs are protected against short circuits and wiring errors.
An Avtron XR125 SMARTSafe encoder–has
– a two-phase output (A,B)
90° out of phase, with complements
(A
,
– B), (A Quad B Output), and a
marker pulse with complement (Z, Z).
Because the XR125 is modular, there are no bearings or couplings
required. This, combined with the latest magneto­resistive (MR)
sensor technology, allows the XR125 to provide superior mechanical
performance and increased reliability.
Output resolution on the XR125 is determined by the sensor only.
Unlike older models, any PPRs can be mixed and matched. Selection
of the rotor is based only on the shaft mounting requirements (and not
PPR).
ADAPTIVE ELECTRONICS
A perfect duty cycle consists of a waveform whose “high” and
“low” conditions are of the same duration (50%/50%). It is possible
over time for the duty cycle and edge separation to change due to
component drift, temperature changes, or mechanical wear. The
Adaptive Electronics extend the life of the XR125 by constantly
monitoring and correcting duty cycle and edge separation over time.

INSTALLATION
WARNING
Installation should be performed only by qualified
personnel. Safety precautions must be taken to ensure
machinery cannot rotate and all sources of power are
removed during installation.
Equipment Group II, Category 2 (Zone 1), Gas group IIC, Dust
group IIIC (ATEX Zone 21): Available as a system only including
XR125 with line driver option 5 and an Avtron Isolator module XRB1
(P/N B35134).
System parameters are:
Um= 250V
Uo (open circuit voltage) = 7.14VDC max.
Io (short circuit current) = 420mA max.
Co (system capacitance) = 13.5uF max.
Lo (system inductance) = 0.15mH max.
Encoder parameters are:
Ui (input voltage) = 7.14VDC max.
Ii (fault current) = 420mA max.
Ci (internal capacitance) = 11.9uF max.
Li (internal inductance) = 0mH max.
1
The isolator XRB1 can be supplied as a separate module for location
in a safe area or in an explosion proof box on a short flexible cable
tethered to the encoder.
Equipment Group II, Category 3 (Zone 2), Gas group IIC, Dust
group IIIC (ATEX Zone 22): Requires an XR125 with line driver
option 7 and a SELV (Energy Limited) or equivalent power supply
which limits voltage and current to the values in the table in the
specifications. If current limit is not inherent in the power supply a
separate fuse between the power supply and encoder can be used
to limit current.
NOTE:
Isolators, encoders and cable must be selected and
installed in accordance with the latest edition of
IEC/EN60079-14 and IEC/EN60079-25. Cable
characteristics must comply with IEC/EN60079-14 and
IEC/EN60079-25 and for zone 1 applications total system capacitance between the isolator and encoder (including cable) must be less than Co-Ci. Total system inductance between the isolator and encoder must be less than Lo-Li.
The equipment is intended for a fixed installation and
should be mounted so as to avoid electrostatic charging.
The XR125 is not considered as a safety device and is not suitable for connection into a safety system.
The XR125 construction materials contain less than 6% magnesium
by mass. These materials are not considered as able to trigger
an explosion in normal operating modes in accordance with the
requirements for category 2 or 3 equipment. These materials are
not known to react with any explosive atmospheres to which the
XR125 may be subject. It is however the responsibility of the end
user to ensure that the XR125 is selected correctly for the potentially
explosive atmosphere in which the equipment is to be put into
service.
The XR125 installation is similar to AV125. Installation and removal
videos for the AV850/AV125 are available on Avtron’s web site. Refer
to the back page of these instructions for outline and mounting
dimensions. The motor must comply with 1998 NEMA MG 1, section
4, for tolerances on diameters and runout for shafts and accessory
faces. Axial float or endplay must be less than ±0.100”.
In preparation for installing the Model XR125 encoder, it is first
necessary to clean both the accessory motor shaft and the mounting
face. These surfaces must be inspected and any paint, burrs, or
other surface imperfections removed.
GENERAL
The motor must comply with NEMA MG1 for dimensions, face
runout, and shaft runout. Axial float or endplay must be less than
+/-0.100” inch.
CAUTION
Do not strike the encoder or rotor at any time. Damage
will result and the warranty will be void. The outer edge
of the rotor may be damaged by scratches, severe
blows, and strong magnetic fields. At installation, clean and remove paint and burrs from motor shaft and mounting face. Apply anti-seize compound (supplied) to each except cam screw rotors.

Installation procedures should be performed only by qualified
personnel. Safety precautions must be taken to ensure machinery
cannot rotate and all sources of power are removed during
installation.
SHIELD INSTALLATION
For top performance on older motors with magnetized shafts and
frames install the XR125 shield. The XR125 also has built-in shields
attached to the housing of every unit. For additional protection,
consider the -004 option for extra sensor shielding.
1. Remove the double-stick tape protection.
2. Align the bolt holes and edges with the motor C-face.
3. Stick the shield in place on the motor C-face or on top of any inboard seal plate.
4. Install rotor as usual, but gage location from the shield.
ROTOR INSTALLATION
Use the dial indicator gauge to ensure motor shaft runout (TIR) does
not exceed (0.004”) [0.10mm]. Apply anti-seize compound to the
shaft.
1. The through-shaft must project at least 1.8” [45.7mm] from the accessory mounting face. If it is greater than 3” [76.2mm] long, use the outboard through-shaft cover, detailed in Figure 3.
2. Slide the rotor on the shaft, ensuring the rotor label “this side out” is away from the motor. The space between the mounting face and the magnetic strip of the rotor must be set to 1.097”
[27.9mm]. The innermost surface of the rotor will be 0.584” from the motor c-face, as shown in Figures 2 & 3. Use Avtron gauges (A35679 or A25355) or housing alignment grooves as shown in Figure 1 to verify position. If using a set screw rotor (TA-T6), apply threadlocker to the set screws (2) and tighten to 25 in-lbs.
STATOR HOUSING ­IN­STALL­­­ATION
NOTE
If additional magnetic shielding (option 004) has been
added to the sensors, be sure to remove the sensors
before installing the stator housing.
The stator housing is retained to the motor using four, 5/8-11 x 4”
bolts and spring type lock washers (supplied). If the stator is to be
sandwich mounted between an accessory such as a brake and the
motor, select the bolt length accordingly. Apply antiseize compound
to the perimeter of the XR125 where it will contact the motor C-face.
Carefully move the stator housing into position, avoiding contact
with the rotor. DO NOT FORCE the housing into place. Install the four
mounting bolts (torque 30 to 35 foot pounds) [47.5-40.6 n-m].
2
CAUTION
DO NOT use silicone sealants or caulk of any kind on
the motor or encoder face; these can cause
misalignment or sensor scraping damage. Do apply
antiseize compound (copper) to the encoder face to
assist in easy removal. The XR125 electronics are fully
sealed; water may enter and leave the rotor area as
needed. Remove the bottom pipe plug in the housing if
frequent moisture buildup is expected.
A special marine-sealed version of the housing is available (option
006) if there is a concern about ice or salt buildup inside the
encoder.
(OPTIONAL) OUTBOARD SEAL PLATE KIT INSTALLATION
For applications requiring shafts to pass completely through the
XR125, Avtron offers an outboard through-shaft seal plate kit with
V-ring seal. See Table 3 for part numbers and Figure 3. Note that
for large through-shaft bores T8 and T9, no seal is available. For T9
through-shafts, no cover is needed.
1. Install the encoder rotor as shown above.
2. Remove the existing cover of the encoder. Retain the screws
and washers.
3. Mount the XR125 stator housing as shown above.
4. Install new through-shaft cover using the (4) #10-24 screws
and
washers from step 2.
5. Apply silicone lubricant or medium grade machine oil (20 weight)
to the outboard side of the cover where the V-ring seal will
contact it.
6. Slide the V-ring seal onto the shaft, and ensure that it is
compressed against the cover. See installation Figure 3.
MOUNTING THE XR125/XR12 WITHOUT A STATOR HOUSING
The XR125 (XR12 sensor+ rotor) may be mounted without the use of
a C-face or XR125 stator housing. See XR12 manual for details.
WIRING INSTRUCTIONS
CAUTION
Be sure to remove power before wiring the encoder.
Be sure to ground the cable shield: Avtron recommends
grounding the shield at the isolator module for Zone 1
applications or in the drive cabinet for Zone 2
applications. Cable should not be grounded multiple
places. An intrinsic safety ground is required at the
XRB1 Isolator Module.
CAUTION
SMARTSafe encoders include a local ground lug for
customer convenience and encoder frame grounding
if required to meet local electric code requirements or
site operator protection standards. This is NOT the
required XRB1 intrinsic safety ground connection
required for hazard protection against ignition of
explosive atmospheres for Zone 1 and Zone 21
applications!
CAUTION
The XRB1 isolator used for Zone 1 and Zone 21 protection requires an intrinsic safety ground to provide
hazard protection. Failure to connect this ground, or providing an inadequate safety ground path can result
in an spark/ignition hazard which can result in property damage, injury, or even death.
For bi-directional operation of the encoder, proper phasing of the two
output channels is important. Phase A channel typically leads phase
B channel for clockwise shaft rotation as viewed from the anti-drive
or accessory end of the motor (encoder mounting end).
See Pinout and Phasing tables for exceptions.
XR125
Wiring option “G” provides a pinout compatible with NorthstarTM
encoders, with a cable shield connection on pin 10. Note that this
option does not ground the shield.
CORRECTIVE ACTION FOR PHASE REVERSAL
1) Remove Power.
2) Exchange wires on cable, either at encoder cable
end or at speed controller end (but not both).
a) Single Ended 2 Phase Wiring
(see wiring diagram)
Exchange A and B connections at the device end.
b) Differential 2 Phase Wiring (see wiring diagram) Exchange either A with A– in the phase A pair OR B with B– in the phase B pair but NOT both.
3) Apply Power.
4) Verify encoder feedback is correct, using hand rotation of shaft, or jog mode of the speed controller.
Interconnection cables specified in the wire selection chart are
based on typical applications. Cable must be selected and installed
in accordance with IEC/EN60079-14 and IEC/EN60079-25. Physical
properties of cable such as abrasion, temperature, tensile sstrength,
solvents, etc., are dictated by the specific application. General
electrical requirements are : stranded copper, 20 through 16AWG
(Industrial EPIC connector type options can use 14 AWG). Each twisted
wire pairs overall shielded with braid or foil with drain wire, .05uf of
maximum total uutual or direct capacitance, outer sheath insulator.
See specifications for maximum cable length. Stranded 20 AWG wire
should not be used for cable runs greater then 61 meters. If 20AWG is
used with EPIC type connector options the wire ends should be tinned.
See wiring diagram for examples of alarm output wiring.
MAINTENANCE
GENERAL
This section describes routine maintenance for the Avtron XR125
Encoder. For support, contact Avtron’s field service department at
216-642-1230. For emergency after hours service contact us at
216-641-8317.
The XR125 SMARTach II circuitry includes a diagnostic package that
includes Adaptive Electronics and a Fault-Check output.
FAULT-CHECK
After power-up and the rotor position is checked by the sensor, the
Fault-Check LED will turn green.
If the adaptive electronics reach their adjustment limit for any
reason, the Fault-Check alarm and LED will notify the drive and
operator of an impending failure. The LED will turn red if the
Adaptive Electronics reach their adjustment limit. This output occurs
before an actual failure, allowing steps to be taken to replace
the unit before it causes unscheduled downtime. Fault-Check
annunciation is available as an “alarm” output through the connector
(Zone 2 configuration only) and as an integral LED.
TROUBLESHOOTING:
If the drive indicates a loss of encoder/tach fault and the XR125
fault-check LED is not illuminated, check the encoder power supply.
If power is present, check polarity; one indicator of reversed power
supply is that all outputs will be high at the same time. If the drive
indicates encoder fault, but the LED shows GREEN, then check the
wiring between the drive and the encoder. If the wiring appears
correct and in good shape, test the wiring by replacing the XR5
sensor module. If the new module shows GREEN, and the drive still
shows encoder loss/tach fault, then the wiring is faulty and should
be repaired or replaced.
3
If the alarm output and/or LED indicate a fault (RED):
1. Remove an end sensor plate or the second sensor, and use the
built-in gauge to check the location of the rotor (see Figure 2.1).
Ensure the label marked “This side out” is facing away from the
motor.
2. Remove the XR125 sensor from the housing. Clean the housing
mounting surface for the XR5 sensor and the XR125 housing. Ensure
the XR5 sensor is directly mounted on the XR125 housing, with no
sealant, gasketing, or other materials, and is firmly bolted in place.
If the alarm output and/or LED indicate a fault (RED) on a properly
mounted XR125 sensor and the rotor is properly located, replace the
XR125 sensor.
STATOR HOUSING REMOVAL
An oscilloscope can also be used to verify proper output of the
XR125 encoder at the encoder connector itself and at the drive/
controller cabinet. If the outputs show large variations in the signals
at steady speed (jitter or “accordion effect”, see figure below), check
rotor position. If the rotor position is correct, the motor or shaft may
be highly magnetized. Replace any magnetized material nearby
with non-magnetic material (aluminum, stainless) (shafts, etc). For
GE CD frame motors and similar styles, Avtron offers non-magnetic
stub shafts (included with all “U” style rotor kits). If variations
persist, consider replacing the sensors with super-shielded models,
option -004.
If the rotor can not be removed by hand, use a gear puller taking
care not to damage the outer magnetized ring.
To remove the stator housing remove the qty 4 5/8-11x4” bolts
holding the housing to the motor. Take care that the housing does
not fall from the pilot and cause the sensors to crash into the rotor.
Damage to the sensor or rotor could result.
ROTOR REMOVAL
Remove shaft rust and burrs before removing the rotor.
THROUGH-SHAFT TA-T9 MA-M9 styles: Loosen the set screws
holding the rotor to the shaft. Remove the rotor by hand, taking care
not to damage the outer magnetized ring.
