4. Adjust the ACCEL trimpot to achieve the desired soft start time. CW rotation will increase accel time.
5. Rotate the CURRENT LIMIT trimpot fully CCW until the motor begins to stall. Apply a full load to the motor. While motor
is stalled adjust the CURRENT LIMIT trimpot CW until a desired current setting is obtained.
6. Adjust I.R. trimpot CW 1/2 way. If motor RPM is inconsistent (jumpy), rotate I.R. trimpot CCW until rotation is stable.
If a newly installed control will not operate, it is likely that a terminal or connection is loose. Check to make sure connections are
secure and correct. If the control is still inoperative, refer to the following chart for reference:
