Only inclined incident light in the front and by the socket on the charging station (not indication green/red/blue)

Cause of error
CCU does not deliver 12 V to the indicator LED at the top of the charging station.

Action 1
Check that the CCU has voltage (24 V). Indicated by flashing diodes (green/yellow/red) in the upper left corner of the CCU (next to the quick connector for the supply):

  • If LEDs do not flash, check that the power supply delivers 24 V. If it has voltage but does not light, replace the CCU.
  • If all LEDs are solid, the CCU must be replaced with a new one.

Action 2
Check that the 4-way quick connector from the CCU to the top card is correctly connected at the bottom right of the CCU.

Charging station black but meter is running

Cause of error  
Alt. 1: Control fuse switched off at bottom of charging station
Alt. 2: 24V power supply switched off (Green LED [DC OK] on power supply off).

Action 1
Make sure the control fuse (1-pin 10A) is switched on.

Action 2
Make sure the power supply receives 220V AC at the L & N ports.

Action 3
Disconnect the red/black cabling from "+/-" ports on the power supply. 
 

Action 4
If the power supply jump starts, it has detected an earth fault from the DC-powered component (controllers, top card, router/switch, etc.) in the charging station.

If [DC OK] remains off, replace the power supply.
