FOR THE SERVICE TECHNICIAN

There are 4 small LEDs on the PC board to help diagnose problems:
Diagnostic – this is the "heartbeat" of the system. When only this LED is slowly
flashing, the system has not detected any failures. If it is lit but not flashing, the
board is defective. If its not lit, either no power is applied, or the board is
defective.
To test the system, press and hold the two Charge Test buttons simultaneously.
If the contactor closes, the CS-40 is operating normally. If a vehicle is available,
connect the charging cable. The contactor should close. If not, the charging
cable or vehicle socket may be defective, or the vehicle is not requesting a
charge.
If the CS-40 detects an internal failure, the Diagnostic LED will blink at a faster
rate. One of the other LEDs may also be lit and indicate the nature of the problem,
such as an inoperative Ground Fault circuitry, or a missing Service Ground.
Load Management Disable: Lit, with a slow-blinking Diagnostic LED, when
either the Cold Load Pickup or External Timer mode are active. This is not a
failure mode, merely a status indicator. The front panel green Charge LED will be
blinking. The CS-40's cable must be connected to a vehicle for this LED to blink.
The front panel light will be off when the cable is not connected.
GFCI Trip: Lit when the unit has detected a ground fault. When a fault has
occurred, the contactor will open, the front panel Red PROTECTION light will
also be lit, and the Diagnostic LED will be flashing at a faster rate. The system
waits 5 minutes after sensing a fault, then automatically attempts recovery. After
several such attempts, it will stay in the Protection mode.
If a ground fault error or an EV connection error has been detected:
1. Remove the EV connector from the vehicle
2. Inspect the connector and the vehicle's charge port. Be sure they are
clean and undamaged.
3. Reconnect to the vehicle. If the fault condition persists, a problem may
exist on the vehicle.
4. Refer to the vehicle owner's manual for instructions on inspecting and
cleaning the charge port.
5. Plug the EV connector back into the vehicle.
6. If the ground fault error is still detected, contact your customer Service
Representative for assistance.
