DESCRIPTION
The Avtron XR47 is a hollow shaft severe duty incremental
encoder (also known as a tachometer or rotary pulse generator).
It provides a two phase, A Quad B frequency (pulse) output, with
complements.
CAUTION
The XR47 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.
When mounted to a machine shaft, the XR47 design eliminates
the need for shaft couplings, adapter flanges, or accessory
mounting faces. The high clamping-force collar holds the XR47 in
place, even under severe vibration & shock. A high-performance
composite shaft insert provides electrical isolation from motor
shaft currents. The shaft insert permits models to fit a range of
shaft sizes from 3/4” to 1 1/8” [19mm - 30mm]; additional sizes
available upon request. An anti-rotation arm prevents housing
rotation while allowing for shaft end float.
The XR47 features extreme shock and vibration resistance.
Combined with potted electronics and huge bearings, this creates our most rugged hollow shaft encoder for severe duty applications such as oil and gas drilling.
The XR47
– –has six signals: (A, B) 90° out of phase, –with complements (A, B). A marker pulse with complement (Z, Z ) is also
provided.
The XR47 has been evaluated to be compliant with IEC600790:2007, IEC60079-11:2011, EN60079-0:2009, EN60079-11:2012,
BSEN 61000-6-4:2007 and BSEN61000-6-2:2005 (Certificates of
conformity: TRAC12ATEX0002X, TRAC12ATEX 0003X, IECEx
TRC 12.0009X, and IECEx TRC12.0001X.)

HOLLOW SHAFT FOR HAZARDOUS
APPLICATIONS
INSTALLATION
CAUTION
Be careful not to damage clamping fingers of hollow
shaft during handling. Do not tighten clamping collar
before installation onto motor shaft.
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.
For installations of Equipment Group II, Category 2
(ATEX/IECEx Zone 1), Gas group IIC, Dust group IIIC
(ATEX/IECEx Zone 21): Available as a system only including
XR47 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.
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 (ATEX/IECEx Zone 2), Gas
group IIC, Dust group IIIC (ATEX/IECEx Zone 22): Requires
an XR47 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 XR47 is not considered as a safety
device and is not suitable for connection into a safety
system.
The XR47 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 XR47 may be subject. It is however the
responsibility of the end user to ensure that the XR47 is selected correctly for the potentially explosive atmosphere in which
the equipment is to be put into service.
1
The XR47 installation is similar to XT45. Installation and
removal videos for the XT45 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.
In preparation for installing the Model XR47 encoder, it is first
necessary to clean the accessory motor shaft. The surface
must be inspected and any paint, burrs, or other surface imperfections removed.
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.
Equipment needed for installation
Supplied:
XR47 Encoder
8b)For thru-shaft applications using the clamping collar system, remove the rear shaft cover, retain the (4x) M4 socket
head screw, and position the XR47 as required.
9) Tighten screws on clamping collar evenly until snug, then
tighten each screw to 95 in-lb [10.7 Nm]. DO NOT USE
A STANDARD RIGHT ANGLE WRENCH. Use only a
T-handle hex wrench or torque wrench with hex bit.
NOTE
To verify proper collar installation: check to ensure the
clamping collar compression washers are
completely flattened. For clamping collar installation,
proceed to step 10.
FOR FOR END OF SHAFT CENTER BOLT MOUNT
STYLE:
6. Using the bolt(s) and thread locker provided, mount the
30mm diameter stub shaft on the motor. Use dial indicator
to verify the stub shaft TIR <0.002” [0.05mm]
Optional:
Required for Zone 1/Zone 21: XRB1 Isolator
Anti-Rotation Arm Kit
7. Remove the sealing plug from the XR47.
Thread Locker (blue)
8. Carefully slide the encoder onto the shaft to verify fit.
Ensure a minimum of 0.050” [1mm] between encoder and
stub shaft surface. DO NOT FORCE. Encoder should slide
on easily. If the encoder does not fit easily, remove it, verify
shaft size, and check for burrs and shaft damage.
Not Supplied:
7/16”, 3/8” Wrenches
3mm, 5mm, 7/16” T-handle hex wrenches or torque wrench
with 3mm, 5mm, 7/16” bits (torque wrench required for
Center Bolt Mounting Style).
Dial Indicator Gauge
The hollow shaft XR47 design eliminates the potential for
bearing and coupling failures from misalignment, however,
excessive housing movement (wobble) may cause undesirable
vibrations. The higher the RPM, the more severe the vibration
will be from housing movement. In a typical installation a
housing movement of 0.007” TIR or less (as measured at the
outside diameter of the main encoder body) will not have an
adverse effect.
1) Disconnect power from equipment and encoder cable.
2) Use caliper gauge to verify motor shaft is proper diameter
and within allowable tolerances: +0.000”, -0.0005” [+0.00,
-0.013mm].
9. Insert center mounting screw (M8x1.0x35 with Belleville
washers provided) through the body of the encoder into the
stub shaft tapped hole and tighten to 424 in-lbs [48n-m]
9a.Replace rear sealing plug into XR47. Tighten to 150 in-lbs
[17n-m]
10)Attach free end of the anti-rotation arm to the bracket tether
using the shoulder bolt provided.
11)Secure free end of the anti-rotation bracket to frame using
bolt or T-bolt provided. Use additional washers as needed
to install the bracket. The bracket should be parallel to the
encoder face, 90 degrees to the shaft to avoid encoder
bearing damage.
12)Turn shaft by hand and verify the shaft turns freely and
does not produce excessive runout/wobble of the encoder
(<0.007” TIR [0.18mm], Total Indicated Runout.)
3) Clean machine shaft of any dirt and remove any burrs.
4) Use dial indicator gauge to verify the motor shaft: Total
Indicated Runout (TIR) <0.002” [0.05mm].
13)Connect cable as shown in wiring diagram.
14)Apply power to the encoder.
5) Install the anti-rotation bracket tether to the face of the
encoder using M5 Hex screws and lock washers, included
with the tether.
15)Rotate the shaft by hand, or using jog mode of the speed
controller and verify proper direction.
5a)(optional) For non-through-shaft (end of shaft) applications,
the optional rear cover may be installed for optimum
performance against dirt, liquid sprays and impacts.
FOR CLAMP COLLAR MOUNTING STYLE:
ENVIRONMENTAL CONSIDERATIONS
Special attention is to be given to conduit runs, interconnection
wiring and NEMA type enclosure mounting.
Follow these steps to reduce potential problems:
6) Loosen clamping collar screws.
1) Always mount connection points, conduit couplings, junction
boxes, etc., lower than actual encoder.
2) For washdown areas, shroud or otherwise cover the
encoder to prevent direct water spray. Do not attach the
shroud directly to the encoder.
NOTE
These screws have factory applied thread locker,
no further thread locker application is required.
7) Insert shaft sizing insert into encoder. DO NOT FORCE.
8) Test Fitting: carefully slide the encoder onto the shaft to verify
fit. Ensure a minimum of 1/8” [2mm] between encoder and
mounting surface. DO NOT FORCE. Encoder should slide on
easily. If the encoder does not fit easily, remove it, verify shaft
size, and check for burrs and shaft damage.
8a) For end of shaft applications using the clamping collar
system, place the XR47 2.75-3.31” [70-84mm] onto the shaft.
Ensure the stub shaft does not contact the optional rear cover
(remove cover if required).
XR47
REPAIRS
REMOVAL INSTRUCTIONS:
FOR CLAMPING COLLAR MOUNTING STYLE:
1. Unbolt tether arm from mounting point on motor.
2. Loosen both clamping collar screws.
3. Slide the encoder off the motor.
2
OR FOR END OF SHAFT CENTER BOLT MOUNTING STYLE:
1. Unbolt tether arm from mounting point on motor.
2. Unscrew & remove the sealing plug from the XR47.
3. Unscrew & remove the center mounting bolt.
4. Slide the encoder off the shaft.
5. (optional) If the encoder does not remove easily, do NOT force.
Instead, use the center bolt lifter method, detailed below:
Center Bolt Lifter Method (optional)
5a.Reinsert and loosely tighten the bolt through the encoder
body into the stub shaft.
5b.Loosen the reinserted bolt by approximately 5 turns. This will
leave the screw head approximately even with the bottom of
the seal plug hole threads.
5c.Reinsert and tighten the sealing plug cap. This will lift the
encoder by pushing on the head of the center mounting bolt.
The encoder should move axially ~0.2” [5mm]
5d.Check to see if the encoder can now be moved axially on
the shaft. If it can, remove the seal cap and center bolt and
remove the encoder.
5e.If the encoder cannot yet be moved by hand, repeat the
lifting cycle as needed: remove the cap, loosen the bolt
an additional ~5 turns, replace and retighten the cap, and
the encoder will move an additional 0.2” [5mm] for each
repetition.
There are no field replaceable parts in an XR47. The unit
should be returned to the factory for all repairs.
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!
Wiring diagrams are shown in the following pages.
Refer to the wiring diagrams and pinout and phasing tables for
specific information on each option.
CAUTION
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 at the use end of the wires.
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.
Interconnecting 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 strength,
solvents, etc., are dictated by the specific application. General
electrical requirements are: strand­ed copper, 20 through 16 AWG
(Industrial EPIC connector type options can use 14 AWG). Each twisted
wire pairs overall shield­ed with braid or foil with drain wire, .05 uf of
maximum total mutual 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 20 AWG
is used with EPIC type connector (zone 2 configurations only) options
the wire ends should be tinned.
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 configurations only)
and as an integral LED.
TROUBLESHOOTING
If the drive indicates a loss of encoder/tach fault and the XR47 faultcheck 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 XR4F.
If the new unit shows GREEN, and the drive still shows encoder
loss/tach fault, then the wiring is faulty and should be repaired or
replaced.
If the alarm output and/or LED indicate a fault (RED) on a properly
mounted XR4F and the rotor is properly located, replace the XR47
An oscilloscope can also be used to verify proper output of the XR47
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), replace any
magnetized material nearby with non-magnetic material (aluminum,
stainless) (shafts, etc). If variations persist, consider replacing with
super-shielded models, option -004.
Zone 1 and Zone 21 applications utilize the XRB1
isolator which requires an intrinsic safety ground to
provide hazard protection. Failure to connect this
ground, or providing an inadequate safety ground
path could result in an spark/ignition hazard which
can result in property damage, injury, or even death.
PHASE A
PHASE B
For bidirectional operation of the XR47, 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 (XR47 mounting end).See pinout and
phasing tables for exceptions.
