F02.04 (D)
1
The driver of main contactor drive coil is shorted, or its coil is disconnected.
Ensure there is no short or low-impedance pull-down between MC and -Vbatt.
Check connections and wiring for interruptions of MC DRIVE coil.
If wiring and connection are correct, the problem is in the controller : Replace it.
2
The main contactor coil has been driven by the controller, but the contactor does not close.
Check the contact in the main contactor drive contactor and if it is not working, replace the
main contactor drive.
4
Before driving the LC coil, the controller checks if the contactor is stuck. The controller drives
the bridge for some tens milliseconds, trying to discharge the capacitors bank. If they don't
discharge the fault condition is entered.
Check the power contact of the main contactor drive and replace it if necessary.
8
Supervisor status is ALARM or WAIT RESET and main contactor is not forced open.
Key OFF / ON.
