Pd17A Rotation Indication Proximity Sensor - BRADEN PD12C Series Installation Maintenance And Service Manual

PD17A ROTATION INDICATION PROXIMITY SENSOR

Early PD17A models have a rotation indicator proximity sensor and hub between the motor and the hoist. If the
sensor is removed or replaced, use the following procedure for adjustment and testing. Refer to the drawing below
for item numbers.
Install a new O-ring (item 108) onto motor pilot. Install sensor hub (item 123) onto motor shaft, positioning the
sensor hub so that one of the lobes will be directly under the sensor port. Install the motor onto the hoist. Install
capscrews and lockwashers (items 101 & 102) securing the motor to motor adapter.
If sensor hub is not correctly positioned with a lobe directly under the sensor port, proper adjustment may not
be possible and severe damage to the sensor and internal hoist components may result.
Install fl atwasher (item 121) and O-ring (item 122) onto new sensor (item 120). Apply a small amount of silicone
sealant to the threads just below the washer and O-ring. DO NOT apply sealant to the end of the sensor or to the
threads of the sensor port where it could be pushed into the hoist. Install the sensor into the motor adapter until
it contacts the sensor hub. Back sensor out of the port 2 complete turns. Attach wire harness to sensor to verify
proper sensor operation. IT IS NOT necessary to operate the hoist motor. If sensor light is on, hold sensor from
turning and tighten jam nut against motor adapter. If light is off or blinks intermittently, adjust sensor inward toward
sensor hub until light remains on, then tighten jam nut.
