Proximity Sensor Replacement
If a proximity sensor fails or is erratic, it should
be replaced immediately.
The unit uses two different types of proximity
sensors: Those that are similar to the photosensors
with a screw connector at the base (Figure 7-58)
and those that have a “pigtail” which terminates
in a plastic connector (Figure 7-59).
Replacing a Screw Connector Proximity
Sensor
Perform only when the unit is OFF
with power disconnected.
Make sure you have the correct type for
the proximity sensor to be replaced. For
more information on sensor location and
type, refer to the
OPERATING PRIN-
CIPLES chapter, Electrical System sec-
tion, Control System subsection.
Turn power OFF at the main disconnect
switch.
Locate the proximity sensor to be replaced
and unscrew the sensor from its connector
plug (Figure 7-60, A).
Loosen the lock nut which secures the
sensor in position (Figure 7-60, B).
Unscrew the proximity sensor from its rail
threads until it is free.
Screw the new proximity sensor into
position.
Follow the steps in
Adjusting Guide
Rail Proximity Sensors
to complete the
procedure.

and disconnect its white connector (Figure
7-61, A). Cut plastic wire ties or remove
any screws which are helping to secure
the pigtail.
As appropriate:
If the proximity sensor is located in a
guide rail, unscrew the proximity sen-
sor from its rail threads until it is free
If this is a transfer assembly proxim-
ity sensor, remove the inner locknut
(Figure 7-63, C) to the sensor can be
lifted out of its position.
Screw or place the new proximity sensor
into position.
