Notes: 1. If Key Switch is not used, a connection must be made between the red wire of Connector P1 (Terminal 3) and quick-connect
Terminal B+ for the control to operate. 2. To reset the control in wig-wag mode, return the Main Speed Potentiometer to the center position.
3. Run Forward and Run Reverse Switches are not used in wig-wag operation. 4. If wiring a fuse or circuit breaker, it must be wired in the
location shown, immediately after the battery positive (+) terminal. The Key Switch must be wired after the fuse or circuit breaker.

KBBC SERIES OPERATING INSTRUCTIONS
TABLE 1
Trimpot Range Description
Timed Brake Delay (T-BRK):
Allows adjustment of the delay time before the brake engages after the control is put into the stop or brake mode.
Stop or brake is initiated by opening the Enable Switch or Key Switch or by closing inhibit terminals.
Adjustment Range: 0.2 – 2.5 Seconds; Factory Setting: 1 Second
Current Limit (CL):

T-BRK
Allows adjustment of current limit setpoint. Typically set to 1.5 times the full load current rating of the motor. When

the control is in Current Limit, the STATUS LED will illuminate red.
Adjustment Range: 0 – 200% of Jumper JB Setting; Factory Setting: 150%
IR Compensation (IR):
Allows adjustment of load compensation for different motors. Smaller motors require more compensation to

overcome losses in armature winding. Typically set by checking No Load to Full Load speed changes.
Adjustment Range: 0 – 25 Volts DC; Factory Setting: 4 Volts DC
Deceleration (DECEL):
Allows for controlled deceleration from full speed to zero speed. Decel works with all stop modes except inhibit.
When inhibit is used, the DECEL Trimpot has no effect, output will go to zero in 0.1 seconds.
Adjustment Range: 0.1 – 15 Seconds; Factory Setting: 2 Seconds

Acceleration (ACCEL):
Allows for controlled acceleration from zero to full speed. Acceleration is active in any turn-on condition, including
Enable, Key Switch, or release of inhibit.

Limits the maximum allowable speed in the forward direction.
Adjustment Range: 60 – 100% Base Speed; Factory Setting: 100%
TABLE 2
RUN RELAY OPERATION
Connector P5 Description
Run Relay Output Contacts Selection (P5): Provides Normally Open or Normally Closed relay output contacts
(use Jumper J8 to select N.O. or N.C. contacts). The Run Relay is engaged when the control is in the Run Mode.
The Run Relay is disengaged when the control is in the Stop Mode or for any fault condition (Main Speed
Potentiometer Fault (open lead), Over Temperature Fault, Overvoltage Fault, Undervoltage Fault, Motor Brake
Fault, Internal Fault (micro failure), and Timed Current Limit.

DIAGNOSTIC LED INDICATORS
LED Description
Power On: This green LED is illuminated when the Key Switch is engaged.
Status: Both green and red LEDs are used to indicate control status. See Table 4 on page 3.
