Control Box V1 LED in control box Red Green Description ON ON CAN Wires from left: 1) Brown (+24V) 2) White (GND) 3) Green (CAN L) 4) Yellow (CAN H) The processor hasn’t been able to start. The problem can be caused by a loose display cable (grey flat cable from PCB to display card) or damaged PCB (processor). Check the display cable or replace the PCB/control box. Blinking 1 Hz OFF The control box is in test state. During start there has been connection between test pins. Check that wires aren’t connected together. OFF Blinking 4 Hz The control box is ok and CAN is working. OFF Blinking 1 Hz The control box is ok but CAN isn’t working. Check the CANwires. or Blinking 1 Hz Blinking 1 Hz Control Box CB V2 1) Normal Control Box - Check that there is a jumper in dead man switch - CAN Enable is free - GND wire from Rubber Gaiter is connected to Case GND CAN Enable (grey) CAN1 H (yellow) (M12 pin 3) CAN1 L (green) (M12 pin 4) Case GND (grey) (Rubber Gaiter) GND (white) (M12 pin 1) +24 V (brown) (M12 pin 2) 2) Remote Control Box - Check that all 6 wires are connected - Check that connector is tightened and wires aren’t twisted and connected together.

If 2024 row is empty, Service Tool isn’t connected to the system - CAN interface (Kvaser) isn’t installed - CAN line is damaged or there is a short circuit - the system isn’t powered up. The combination of the software & runtime versions is also important. SW 1.04 & RT 2.15 are compatible with each other but 1.04 & 2.13 aren’t.
