TRIMPOT ADJUSTMENTS
Before power is applied, the speed potentiometer and trimpots should be preset as fol-
lows:
TRIMPOT PRESET
1. Rotate Speedpot fully CCW.
2. Rotate Max trimpot CW 1/2 way.
3. Rotate Current Limit trimpot fully CW.
4. Rotate Min trimpot fully CCW.
5. Rotate Accel trimpot CW 1/2 way.
6. Rotate I.R. trimpot fully CW.
DC power can now be applied to the system and the control adjusted as follows:
TRIMPOT ADJUSTMENT
7. Increase the MIN trimpot in a CW direction until the desired minimum speed is reached.
8. Turn the Speedpot fully CW and adjust the MAX trimpot until the desired maximum
speed is reached.
9. Adjust the ACCEL trimpot to achieve the desired soft start time. CW rotation will increase
accel time.
10. Rotate the CURRENT LIMIT trimpot fully CCW until the motor begins to stall. Apply a
full load to the motor and adjust the trimpot until a desired current setting is obtained.
11. Adjust I.R. trimpot CW 1/2 way. If motor RPM is inconsistent (jumpy), rotate I.R. trimpot
CCW until rotation is stable.
IMPORTANT: DO NOT EXCEED CURRENT LIMIT AMPERAGE RATING. (see below)
LEESON SPEEDMASTER™ low voltage controls = 60 AMP MAX
Adjustment is now complete for the 175135.00REV1 and 175136.00REV1 models
and the ammeter may be removed.
