3.3 FUNCTION DESCRIPTION

SEQUENCE OF CHARGING PROCESS
1. INITIALIZATION
After the operating voltage is applied, the module carries out initializations and function tests indicated by an LED flashing
sequence (which begins and ends with a two-second white indication) and then waits for vehicle connection .
2. CHARGING PROCESS
The module waits for a charging cable or vehicle to be connected (status A) and continually blinks the blue LED . If an approved
connecting cable has been connected (see Proximity) and status B is indicated by the vehicle, the module changes the LED to be
steady-blue and activates the interlock .
After interlocking, the charging enable P1/P2, P3/P4 or P4/P5 is activated (see Proximity) if the vehicle is signaling status C . The
charging process is activated, and the LED is changed to steady-green . If status D is indicated (ventilation required) then charging
and interlock are deactivated as the EPC does not provide a fan-enable mechanism, and the LED is changed to steady-red .
In the fault condition the charge enable P1/P2, P3/P4, or P5/P6 and the interlock are deactivated and the LED is changed to
continually blink red .
