(AC). Secure the encoder mounting flange (AB) to
the motor housing (AD).
4. Using the included .050 inch hex wrench, remove

5. Apply a small amount of blue (medium) thread
locker to the set screws (AA) and screw them back
into the encoder. Tighten by hand.
6. Plug the encoder cable into the encoder and the
control board.

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).

Reinstall the Motor Cover

1. Reinstall the motor cover onto the motor housing.
2. Using a 6 mm hex wrench, install the four bolts that
hold the motor cover. 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

NOTE: Alarm code END_ (blink code 5–6) appears
during this sequence and disappears when the
sequence is complete.
1. Apply power to the motor to start the automatic
calibration process.
2. Wait for the motor to go through the calibration
sequence.
a. The motor slowly goes through five complete
cycles.
b. The motor moves toward the center of the
stroke and moves up and down within a small
range very slowly.
NOTE: It might not be obvious that the motor is
moving.
