Appendix C - Setting Home Position on Pumps
The motors driving the pumps have absolute encoders
on them and do not lose their position on loss of power.
However, if the encoder cables are disconnected, the
home positions need to be reset.
NOTE: If the electrical connections between the
encoder and drive need to be disconnected, make sure
the actuator is in the home position before disconnect-
ing the connector. This ensures everything is in position
when the connector is reattached and the below steps
will not be necessary to perform.
1. Login as supervisor and go to the SETUP HOME
screen.
2. Disable the drives. The motors will be able to be
turned manually.
3. Locate home position for the base pump.
a. Locate the base pump so the actuator is
extended about 4-1/2”.
b. Remove the motor from the actuator.
c. Using a wood dowel rod, turn the coupling in the
actuator to move to the home position. CW
retracts, CCW extends.
d. Reattach the motor to the actuator.
