ERROR CODE: E04
ERROR TYPE: Faulty contactor feedback
DESCRIPTION: If a false feedback is received even though the contactor should not be active, this error is displayed. A reset operation is required after the error is corrected.
TYPE: LOCKOUT
SOLUTION:
1- Reset the error.
2- If you still receive the error after reset, make sure that the contactor feedback cables are connected to terminals no. 13 and 14.
3- If the error persists even though the feedback cables are connected to the correct terminals, measure the resistance between terminals no. 13 and 14 when the contactor is not energised. If a value other than open-circuit is displayed, replace the contactor. 4- If the contactor is steady, check the end-to-end integrity of the feedback cables.
5- If the cables are also solid, the mainboard must be replaced.
