PROBLEM
PROBABLE CAUSE
SOLUTION
Unit will not
operate

supply
1) Check connection of control
panel
2) Fuses or Circuit breakers
tripped on the control panel
2) Check fuses and circuit breakers
Unit starts but
then stops
1) Wrong rotation of the
screw feeder
1) Change the polarity
2) Screws are obstructed
2) Clean the screw feeder internally
3) The capacity is too high
3) Check the amperage and the
capacity
4) Motor fault
4) Check the cause (see point 3)
and after that repair
5) Faulty Motor or gear
reducer
5) Check the cause (see point 2)
and then replace the component
6) The outlet is blocked

1) General checks
•
Check that the screw conveyor starts without any problems even after long
stops.
•
Check that the environmental conditions do not interfere with machine
functioning.
2) Electrical part checks
•
Check that there are no voltage problems due to the contemporary start-up of
different equipment.
•
Check that there is a power generator.
•
Check that the engine is properly connected and that the wires are well fixed.
•
Check that the regulation of the thermal sensor of the engine in the general panel
is compliant to the data written in the engine plate.
•
Check that the engine rotates in the correct way.
•
Check the power consumption of the engine when the screw conveyor is empty,
at the beginning and when the screw feeder is working.
•
Check that the diameter of the wire is suitable for the power used.
