PANEL OPERATION
ENGINE START
Rotate the key to the right to the Crank position and hold while the engine starting circuit is energized
and rotates the engine. Once the engine fires, release the key and a spring will rotate the key back to
the Run position where it will stay until you desire to turn the engine off.
For Scania engines, the key provides a start/run signal to the controller (into Connector A, Pin 14 of the
controller). Upon receiving the key start signal, the controller broadcasts a “START” command over
the J1939 CANbus to the engine ECU. Upon receiving the “START” command message from the
controller, the engine ECU initiates engine start.
ENGINE STOP
Return the engine to LOW SPEED and DISENGAGE the clutch. Once the clutch is DISENGAGED and
the engine is at LOW SPEED, rotate the key to the Off position. The key removes the run signal from
the controller. With the run signal removed, the controller sends a “STOP” command message to the
engine ECU. Upon receiving the “STOP” command message, the engine ECU initiates engine stop.
ENGINE SPEED CONTROL
The control panel controls the engine’s speed over the CANbus using J1939 Torque Speed Control
(TSC1). The unit is set up with a special TWO-STATE throttle system.
•Low Speed (STATE 1 = 750 rpm)
•High Speed (STATE 2 = 1800 rpm)
The low and high speeds are selectable via a password protected menu setting.
The engine starts at low speed. At low speed, throttle is adjustable via the UP and DOWN arrow
buttons on the controller between 650 rpm and 1200 rpm.
When the “CLUTCH” button is pressed for 3 seconds, the controller does the following:
1) Sends a CLUTCH ENGAGE command to the clutch system (via the CANbus)
2) Increases engine speed to HIGH SPEED
