The problems listed below refer to the controller. Further faults, caused by the
working unit or the magnetic vibrator, can be found in the appropriate operating
manual.
Faults Cause(s) Remedies
å
Vibration con-
veyor device does
not function.
No mains voltage. No LEDs light up. Correct fault source, check fuse(s)
Mains fuse blown. No LEDs light up. Replace fuse, check current consumption if neces-
sary
Supply line interrupted. No LEDs light up. Determine cause and replace supply line
Full mains voltage present at terminals 3 and 4
(identical to voltage at terminals 1 and 2).
Magnetic vibrator is not connected or supply line
interrupted.
Correctly connect magnetic vibrator.
Thyristor short circuit, vibrator hums Have thyristor changed by AViTEQ Vibrationstech-
nik
Defective component(s) in controller (thyristor,
supply transformer, board or similar), no voltage at
output terminals 3 and 4
Repair required
send controller to AViTEQ Vibrationstechnik.
Vibration-width adjuster (potentiometer) or its
lines are defective
Replace vibration-width adjuster or its lines, con-
sult with AViTEQ Vibrationstechnik if necessary
Terminals 12 and 13 are not connected with a
bridge.
Check switch (relay) or optical coupler, if installed,
or install bridge; or connect the terminals with a
switch (relay) or an optical coupler.
Signal line(s) interrupted Replace signal line(s)
Vibration con-
veyor capacity too
low
False controller selected Connect correct controller, check AViTEQ Vibra-
tionstechnik delivery information
Voltage at controller output (terminals 3 and 4) too
low
Check mains voltage and controller setting. Check
magnetic vibrator and controller voltage details; if
necessary, increase vibrator voltage at trimming
potentiometer R1 or consult with AViTEQ Vibra-
tionstechnik.
Voltage at vibrator input too low Supply line too long (… high resistivity), change
supply line (length, cross section), consult with
AViTEQ Vibrationstechnik if necessary
Deviation from nominal frequency at in-house cur-
rent supply
Re-tuning is necessary;
consult with AViTEQ Vibrationstechnik
Potentiometer not connected (terminals 5, 6 and
7), no external control input present
Connect potentiometer or external control input
Controller delivers false drive frequency; as a
result the vibrator current I
v
is too high and the
fuse can blow.
Repair or readjustment necessary. Send controller
to AViTEQ Vibrationstechnik.
