Trouble-shooting

1 Check all connections.
2 Check the power supply.
3 If it is a three-phase drum motor, check the voltage
between all three phases. This must be equal.
1 Ensure that the ambiant airtemparature does not
exceed 40°C.
2 Avoid electric overload.
3 Check FLC with a clamp ammeter, the current
consumption should not exceed the FLC value
indicated on the data plate.
4 Check the conveyor for belt slip.
1 If it is a three-phase Drummotor, check the voltage
between all three phases. This must be equal. Also
check for possible interruptions in the winding.
2 If it is a single-phase Drummotor, the start capacitor(s)
is/are to be checked as well as the start switch. Check
for possible interruptions in the winding.
1 Check for a short circuit.
2 If a short circuit is not present, reactivate the power
and check the FLC using a clamp ammeter.
1 Is the Drummotor correctly mounted (page 26)?
2 Check whether the indented arrow on the mounting
shaft opposite the junctioin box end points upwards.
3 Check if the tension of the conveyor belt is not too
high.
1 Ensure correct electrical connection of the brake
Drummotor.
2 Check the supply voltage of the Drummotor and of
the brake.
