Position Sensor Replacement Kit 24W920

Reset the Dip Switch

To calibrate the unit, you must toggle a dip switch on
the control board. There are two dip switches located
on the upper control board to calibrate the unit. Reset
either dip switch by toggling it to the opposite state.
This signals the control board that a replacement part
has been installed. The next time the unit is powered, it
runs an automatic calibration sequence.
NOTE: If you are performing more than one repair
procedure, the dip switch only needs to be toggled into
the opposite state once.

Reinstall the Electronics Cover

Be sure that no wires are pinched between the
electronics cover and the motor housing. Pinched
wires may damage the control board and will impair
explosion-proof safety.
1. Reinstall the electronics cover onto the center
housing.
2. Using a 6 mm hex wrench, install the 12 bolts.
NOTE: Ensure that the lock washers are still in
place.
3. Torque the bolts to 15 ft-lb (20 N•m).

Apply Power to the Motor

1. Apply power to the unit to start the automatic
calibration process. The motor output shaft runs up
and down over the course of several minutes.
Halfway through the automatic calibration process,
the motor output shaft pauses as it moves to the
next step.
2. Ensure that the automatic calibration process is
complete before you continue.

Reattach the Pump Lower

1. Jog the output shaft on the pump lower and
reconnect the coupling nut.
2. Torque to the proper level according to the
appropriate pump manual.
