Troubleshooter (Incl. Error Mode) - E&P HYDRAULICS V6A Bedienungsanleitung

Troubleshooter
In case of an error message, check whether the hand brake is engaged, whether the
ignition is switched on, whether the battery has sufficient voltage, whether the oil level
is correct, whether there is any damage to the cylinders, and check the cables. If this
does not lead to a solution for the malfunction, the malfunction could be located in
the drive units. As the drive unit does not have any repairable parts, the search for
malfunctions and the maintenance work to the electronics is limited to replacing the
abovementioned components (also see page 15 of the assembly manual).
The error mode:
• I f the ignition lock is not switched on or the hand brake is not engaged, the complete
unit cannot be switched on, unless the jacks have been lowered and the hand brake
is being disengaged, in which case the 'park brake' led will flash and the buzzer will
beep. You are now able to switch on the unit with the on/off button.
• I f, when retracting the jacks, the pump is running on overpressure for a few seconds,
the retracting action should stop (in both manual and automatic mode).
• I f the jacks are retracted and the pressure switch on the pump de-energizes, the unit
will retract the jacks again for a few seconds, if the ignition is switched on.
• A timer will run, which will count up when the pump is running and count down
when the pump is not running. If this timer reaches a value that is too high, the pump
will stop running in order to prevent overheating.
• U nder normal circumstances, all LEDs are off and the unit will only respond to the
'on/off' button (switch on).
