Fault
4 - Feeble motor rotation with
"groaning"
5 - Cable cannot be inserted
6 - The cable slides or slips on the
uphill
7 - Load descent is no longer
slowed: the cable slides despite
the motor being stopped
8 - The motor cuts out during a
manœuvre
Possible causes
• Defective power supply.
• Major drop in voltage.
• Electromagnetic brake jammed
shut.
• Lack of torque on start-up
(defective permanent condenser or
motor winding coil burnout).
• Defective reduction gear or brake.
• Overload.
• Overly thick cable.
• Defective cable tip.
• Cable deformation.
• For a three phase model, reversed
controls.
• Worn interior guiding parts.
• Overly thin cable.
• Cable wear more than 10% of the
nominal diameter.
• Heavy wear to the tightening
system.
• Brake maladjusted.
• Worn brake shoes.
• Brake shoes tainted by oil or
grease.
• Overload.
• After intense usage the motor is
too hot and the heat probe triggers.
Action
• Check the power supply voltage.
• Return the equipment to a
TRACTEL approved repair service
®
if the power supply voltage or
surges are not the cause.
• Reduce or hoist the load.
• Check the diameter. Replace with
a cable of the correct diameter.
• If necessary, re-weld the end of the
cable using a blowtorch. Grind and
round off.
• Discard the deformed part. Cut,
re-weld and grind the cut end.
• Press the "Down" button. If the
cable engages normally, press
the "Up" button to release it
and reverse the phases on the
connector set up for this purpose.
• Should none of the above causes
be revealed, send the minifor
to a TRACTEL approved repair
®
service.
• Check the diameter of the cable
as shown in the instructions. If
the cable should prove to be non-
compliant or worn, discard it and
replace with a new one.
• If the cable is normal, send the
minifor to a TRACTEL
™ ®
repair service.
• Adjust the air gap.
• Return the equipment to a
TRACTEL approved repair
®
service.
• Wait for cooling.
