HALL EFFECT SENSOR ADJUSTMENT
NOTE: Normally the Hall Effect sensor does not
need adjustment, but may go out of alignment due to
shipping vibration or rough handling.
These operators use an internal entrapment protec-
tor system. This system consists of the GL control
board, magnet, and Hall Effect sensor. It may
become necessary to adjust the sensor for correct
alignment. To do so please perform the following
steps:
1. Loosen the two screws holding the hall bracket to
the frame.
2. Adjust the hall effect bracket so that the hall effect
board is:
a. Parallel with the pulley.
b. .020" away from the pulley's magnet. Use
a feeler gauge to measure the distance.
TO AVOID SERIOUS PERSONAL INJURY OR
DEATH DISCONNECT ELECTRIC POWER
BEFORE ADJUSTING HALL EFFECT.

net clears the hall effect board.

hall effect assembly accordingly.
