F1 Main motor tripped
Possible cause:
The over-current relay of the main motor has tripped and the motor has stopped.
Rectification:
Reset the over-current relay in the control cabinet. The electrical diagram is in Appendix.
If the fault recurs, check that the hydraulic pressure does not exceed maximum value according to the hydraulic diagram. Check also the over-current relay, the windings of the motors and the motor cables for sign of short-circuiting, wear or damage.
