STANDARD FEATURES
• Provides smooth variable speed capability for mobile equipment.
• Maintains variable speed control as batteries discharge.
• Adjustable min speed, max speed, i.r. compensation, current limit, and accel.
• Inhibit terminal permits optional start-stop without breaking battery lines.
• Speed potentiometer, knob, and dialplate included.
• Increases range OR running time of battery operated equipment through high
efficiency.
• Automatic current limit foldback decreases current limit to 50% of setpoint when

WARNING:
MAKE CERTAIN THAT THE POWER SUPPLY IS DISCONNECTED BEFORE ATTEMPTING TO SERVICE
OR REMOVE ANY COMPONENTS!!! IF THE POWER DISCONNECT POINT IS OUT OF SIGHT, LOCK IT
IN DISCONNECTED POSITION AND TAG TO PREVENT UNEXPECTED APPLICATION OF POWER.
ONLY A QUALIFIED ELECTRICIAN OR SERVICEMAN SHOULD PERFORM ANY ELECTRICAL
TROUBLESHOOTING OR MAINTENANCE.
AT NO TIME SHOULD CIRCUIT CONTINUITY BE CHECKED BY SHORTING TERMINALS WITH A
SCREWDRIVER OR OTHER METAL DEVICE.

NOTE:
When mounting the control, allow clearance above

CAUTION: DO NOT MOUNT CONTROLLER WHERE AMBIENT TEMPERATURE IS
OUTSIDE THE RANGE OF -10° C (15° F) TO 45° C ( 115° F).
INSTALLATION & HOOK-UP
Before attempting to wire the control, make sure all power is disconnected. Recheck code
designation to assure proper voltage is present for the control. Caution should be used in
selecting proper size of hook-up wire for current and voltage drop. Note: The battery and
armature wire size on 175135.00REV1 and 175136.00REV1 models must be a minimum of 12
gauge.
Warning:
Do not reverse positive or negative battery leads, this will damage the control. To
change motor direction, interchange the positive and negative Armature leads.
Refer to the following wiring diagrams for proper location when connecting DC Voltage,
Armature, and Speedpot wires to the control.
CAUTION !! TURN POWER OFF WHILE MAKING CONNECTIONS.
To properly adjust the CURRENT LIMIT setting, a DC ammeter should be placed in series with
the armature line. This meter can be removed after the control is adjusted.
Warning:
Improper installation or operation of this control may cause injury to
personnel or control failure. The control must be installed and grounded
in accordance with local, state, and national safety codes.

ENGAGE OPPOSITE DIRECTION UNTIL MOTOR HAS COME TO A COMPLETE STOP. Failure to do so may
result in damage to the control.
INHIBITING THE CONTROL - There are two methods that may be used to shut down the output without having
to break the battery supply (ie. inhibit the control).
Using inhibit input - provide fast startstop by bypassing accel/decel circuit

TRIMPOT ADJUSTMENTS
Before power is applied, the speed potentiometer and trimpots should be preset as follows:
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.

IN CASE OF DIFFICULTY
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:
