6.2 Troubleshooting
Two types of problems may occur:
l
Faults during installation and commissioning
l
Faults during operation
Disassembling the small conveyor unit and the controller carries the risk of
damage and lethal injury! There are no components inside of the units which could
be repaired or serviced by the user.

Do not attempt any repairs! Never disassem-
ble the small conveyor unit or the controller for repair purposes, not even if the
power is disconnected! In the event of device malfunction, ship the entire unit to
AEG Vibrationstechnik, Frankfurt, Germany! AViTEQ will ensure the fastest repair
possible!
Faults during installation and commissioning
l
Excessive heat-up to operating temperatures above 75°C on the magnetic
system and short circuits between windings
ã
Check if the air gap is set too wide! An air gap that is too wide results
in an increased current consumption.
ã
Check the working weight! Is it too large? The drive may be operating
in a critical range with power loss and increased current consumption.
ã
Does the controller match the small conveyor unit? The small conveyor
unit isn't connected directly to mains by any chance, is it?
l
Knocking sounds and destruction of the small conveyor unit
ã
Check if the air gap is set too narrow!
ã
Check whether the working weight is too low!
ã
Does the controller match the small conveyor unit? The small conveyor
unit isn't connected directly to mains by any chance, is it?
ã Have the spring mounting bolts been loosened? They must be tighte-
ned with a specified torque - otherwise the eigenfrequency will shift.
In this case, you should send the small conveyor drive to AViTEQ for
realignment!
l Rattling noises
ã Check whether the working unit is firmly attached to the small con-
veyor drive and cannot move! For example, the attachment bolts of
the working unit may be too long and may hit the bottom of the
threaded holes.
DANGER!
