CS 3-Phase Installation Manual

FOR THE SERVICE TECHNICIAN

There are four 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 on but not flashing, the board is defective. If the LED is
not slowly flashing, 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 3-Phase 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 3-Phase detects an internal failure, the Diagnostic LED
will blink at a faster rate. One of the other LEDs may also turn
on and indicate the nature of the problem, such as an inoperative
Ground Fault circuitry, or a missing Service Ground.
Load Management Disable: Turns on, in conjunction 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
blink. The CS 3-Phase'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: Turns on 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 turn on, 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.
