F3 Conveyor tripped

Possible cause:

The main motor and oil cooler have stopped. The over-current relay of the oil cooler has tripped. The soft starter or frequency control has tripped.

Rectification:

Check that the conveyor is not overloaded with material. Check that the drive, pul¬leys and/or chains of the conveyor belt are not obstructed. Clear any obstruction.
Reset the over-current relay located in the control cabinet. The electrical diagram is in Appendix.
If the fault recurs check the over-current relay, the windings of the motor and the motor cables for signs of short-circuiting, wear or damage.
Lethal voltage. Moving parts. Only qualified personnel (5, 12, 14, 19)
