FAQs AND REMEDIES
The drive will not operate:
• Check the domestic fuses and power supply
• Has the motor been connected correctly? Check that N L L have been correctly connected.
• The limit switches have already been adjusted and both limit switches turned to the minimum. Turn both limit switches by several turns in the plus
direction and test again.
• The motor became too hot and cut out. Try again after about 30 minutes cooling time.
The drive will only run in one direction:
• The drive is already at the limit switch. Adjust the limit switch or travel the motor in the other direction for several seconds so that it can travel away
from the limit switch.
• Install drive. The limit switch can only function in this way.
The drive cannot find the limit switch:
• The drive is not installed. Because of this the limit switch will not turn.
• The limit switch is wrongly set. Remove the hanger and travel the motor downwards until it switches off. Then turn the limit switch for OPEN for a
long time in the minus direction. Keep testing in the meantime. Then start the setting work again.
• The adapter ring on the motor, which actuates the limit switch, does not turn or is not mounted.
• Run installed motor without hanger downwards until it switches off. By briefly running upwards check whether the motor didn't possibly need a cooling
break and had therefore switched itself off.
The drive is noisy and will not run:
• The clutch drive ring on the end of the motor has come off or was not plugged on.
• The motor will not turn because the roller shutter is jammed.
• The motor is not getting sufficient power because of a poor feed cable.
• Another motor is attached to the same switch. Not permitted! Only operate one switch with one motor or use an isolating relay (accessory).
• Remove locks, handles or stoppers on the roller shutter.
The domestic fuse was tripped:
• The fuse was overloaded due to the operation of several motors with isolating relays. It is necessary to have the domestic electrical system
modified by a specialist.
• Incorrectly connected switch which has caused a short-circuit.
• Isolating relay incorrectly connected (only relevant if several motors are used with one switch).
• Two switches have been operated with one motor and the switches were depressed differently. Not permitted! Use isolating relay (accessory).
The drive is noisy:
• Close the roller shutter box.
• The drive has too much axial play (shaft). The roller shutter hanger or the shaft bearing is in poor condition and causes the noise. It is necessary to
change the guide rails or the fixing on the shaft.
• Wall bracket is faulty. Special rubber dampers for wall brackets can be obtained from your specialist dealer.
The drive does not unwind neatly from the open position:
• The UP end position is too high. Set the roller shutter jacket 3-5 cm lower.
• The run-in taper at the upper end of the guide rail is not present or is bent.
• The end position of the roller shutter has changed and is higher than it should be because the jacket winds shorter
• The guide rails are defective, they possibly require lubrication.
BATTERY DISPOSAL
Batteries and rechargeable batteries may not be disposed along with domestic waste, but are obliged to
be returned. After use they can be returned free of charge locally e.g. in trade or at municipal collecting
points. Batteries and rechargeable batteries are marked with a crossed waste container as well as with
the chemical symbol which describes their toxic element, "Cd" for cadmium, "Hg" for mercury and "Pb"
for lead.
