A1 (12 V DC): No vehicle connected
A2 (12 V PWM): Only temporary transition state,
enters the A1 state

C Yes Closed Vehicle
ready
6 V R3 = 1.3 kΩ ±3%
Ventilation not required
C1 (6 V DC): EVSE not ready, charging process
aborted. Transition state; possible as a perma-
nent state only in the event of a simplified
Control Pilot.
C2 (6 V PWM): Charging process active
D 3 V R3 = 270 Ω ±3%
Ventilation of the charging area required
D1 (6 V DC): EVSE not ready, charging process
aborted. Transition state; possible as a perma-
nent state only in the event of a simplified
Control Pilot.
D2 (6 V PWM): Charging process active
E Yes Open No 0 V Vb = 0: EVSE
Mains problem or mains not available, short circuit on
the Control Pilot
F Yes Open No EVSE not
available
EVSE not available
