REPAIR/ADJUSTMENTS
Repairs
There are no internally serviceable components in the motor
speed controller. If a controller is faulty then it must be replaced.
Note: Opening or disassembling a controller will void the
controller warranty.
Adjustments
There are two or three adjustments available:
1: Acceleration Ramp: How fast the controller ramps up to full power.
2: Plugging Current: How much current is provided when reversing direction.
3: Current Limit: Maximum current (not available on all controls).
These adjustments are accessed by removing the button head
screws in the housing. The control may need to be removed from
the panel to gain access to the screws.
The adjustment potentiometers (pots) are located just under the
screws. Use an insulated potentiometer adjustment tool to turn
the pots. Each pot has built in stops. DO NOT turn past the stops
or the pot may be damaged.
1: Acceleration Ramp: Turn clockwise for faster acceleration.
2: Plugging Current: Turn clockwise for harder plugging..
3: Current Limit: Turn counterclockwise to lower maximum
current.
This section is one section of a complete service
