Hall Effect Sensor
Replacements 1. Ensure there is no power to the equipment.
2. Note the location of all wires and the orientation of the Hall Effect sensor.
For quick reference when checking the orientation of the Hall Effect
sensor, look for the white arrow.
3. The load cable must be disassembled to allow removal of the Hall Effect
sensor. Remove the hardware to allow the cable to slide out.
4. Remove the plug connecting the sensing wire to the Hall Effect sensor.
5. Remove the four screws on the base of the Hall Effect sensor, and remove
the Hall Effect sensor.
6. Replace the Hall Effect sensor. Note the arrow must be oriented as shown
in the illustration below.
7. Slide the load cable back into place and secure the hardware.
8. Plug the connector back into the sensor. The plug is keyed so that it
cannot be plugged in incorrectly.

ATTENTION: To prevent electrical shock, ensure the main power has been
disconnected before working on the Hall Effect sensor. Verify that all circuits are
voltage free using a hot stick or appropriate voltage-measuring device. Failure
to do so may result in injury or death.
IMPORTANT The Hall Effect sensor and wires must be in the proper orientation. Note the
position before disassembly.
