10 Trouble-shooting

Works at electrical installations or machines are only to be exectuted by skilled electrical personnel in
accordance with the electric engineering rules. Before attempting repair, the load has to be removed
or secured. Always pull out the plug before opening the control box.
Interruption
TOPLIFT does not work.
Motor hums but does not start
Lift does not pull rated load.
Load slides downward when push-
ing the UP button.
The motor heats up quickly, also
with a small load.
The carriage does not move up
when pushing the UP button.
Motor heats up and stops.
The TOPLIFT does not react of or-
ders, although the current supply is
good.
31
Cause
No voltage.
EMERGENCY-STOP button is
set.
Brake rectifier defective.
Brake coil defective.
Supply voltage is not constant.
Supply voltage is not constant.
Operational capacitor defective.
Starting capacitor defective.
Supply voltage or supply line not in
order.
Operating factor of the TOPLIFT
is to high.
Upper limit switch is defective or
faulty adjusted.
The limit switch cable is damaged
Plug or socket connection of the
limit switch is defective.
Thermal contact of the motor was
tripped.
One of the control fuse defective.
Measures
Check Supply voltage and the slow secured
(16A)
Button (red) turn and pull.
The brake rectifier is connects the brake with
approx. 200V d.c.. The fuse is located on the
motherboard next to the motor connectors. The
defective fuse can only be exchanged by
fuse "1A slow". If it happens again, please
check the brake coil.
The brake coil has a resistance between 1.7
and 1.9k Ω.
Feed line too long. Max. length is 40m
∅ 2.5 mm²./
Check supply voltage, it must not be less than
207V during start of upward travel with load.
At 110 Voltage must not be less than 105V dur-
ing start of upward travel with load.
Replace, see to it that the right capacitor is re-
placed.
Replace, see to it that the right capacitor is re-
placed.
Check as described above.
Reduce maximum operating factor to 40%.
Check limit switch and if necessary replace, see
spare parts list.
Check cable and if necessary replace by an
electrician
Check and replace. (by an electrician)
Let the motor cool down, check voltage and
supply line reduce load if necessary. After cool-
ing down the motor can be operated again.
Because of a short circuit in the limit switches or
at the suspended controls, one of the safety
fuses on the control board (by the side of the
trafo) is fused. The defective safety fuse shall
be replaced with an identical fuse.
Prim.=0..2A slow or sec.=630mA slow.
