Installation Instructions

Rotary Encoders - Mounting

Page 6

Attach your hub/scale
assembly to the rotary
device. Refer to the
interfacedrawing. The
reflective surface of the
scale must face the
sensors.

2Install the sensors on your mounting surface referencing the
appropriate datum surface as shown on the interface drawing.
Use 2 washers per mounting screw.
Benching pins may be used to locate each sensor if the system
mechanical tolerances are adequate. See data sheet for alignment
tolerances, or keep mounting screws loose for sensor alignment if
benching pins are not used.
Be sure the source power is off before
connecting the SmartPrecision plug.
Connect the SmartPrecision electronics to the controller
using the pinout diagram described on the interface
drawing.
Insure proper system grounding. Refer to the procedure
on pg 9.
Power up the system. The Power and Signal indicators for
both sensors will illuminate.

CAUTION: observe precautions for handling elec-
trostatic sensitive devices.
Route the sensor cables through your equipment
to the Dual Axis SmartPrecision electronics module.
A) Remove the three cover screws and the top
half of the connector housing. Do not pull on
the 25-pin D-sub connector or the circuit
board under the insulation layer.
B) Attach each sensor's 5 X 2 connector to the
mating 5 X 2 connector on the circuit board.
C) Route the sensor cables through their channels
in the center of the connector body and place
the cable's hex sleeves in the matching recesses.
Attach the top half of the connector housing
to the bottom half using the three cover screws.
