FAQ AND TROUBLESHOOTING (remote control)
The UP button functions as the DOWN button
• The motor turns in the opposite direction (left installation) than that set
by default in the factory (right Installation). See item DELETION OF
ALL REMOTE CONTROLS then PROGRAMMING THE FIRST
REMOTE CONTROL
Programming new remote control doesn’t work.
• The “master” remote control is required for this.
• The shutter drive has reached its limit position and this positive result
was not immediately recognisable?
• Too far away from the drive?
• See also under Range.
What sort of range can I expect?
• This is normally no problem if you are in the same room as the drive.
• No function can be guaranteed over several storeys or through walls.
Range is short
• Antenna should not be rolled up.
• Do not wind the antenna around the connection cable.
• Re-position antenna (do not extend it).
• Shutter box blocks signal. Extend antenna somewhat and allow it
project out of the box (different position).
• Very close to appliances such as television, stereo unit, microwave,
dishwasher or washing machine - a high level of electromagnetic
radiation can be emitted, thus reducing the range.
• Battery too weak.
• If the LED is shining, the battery is normally strong enough.
• If the range has gradually diminished over weeks, the battery is
weakening and should be replaced.
• As a test, you can open the shutter box and try it out with the antenna
simply hanging down. If this proves successful, the antenna needs to
be re-positioned as the shutter box is blocking the signals.
Range subject to severe variation/ fluctuation periodically (hourly)
• The remote control transmits on a frequency of 433MHz.
If other signals are transmitted on this frequency, the range may be
reduced significantly as the mixture of the signals causes the receiver
in the motor to block release for safety reasons.
• Weather stations or radio-controlled temperature measuring devices
transmit signals in cycles of 30-90 seconds for approx. 1 second.
• Hand-held remote controls for garage doors transmit signals briefly
when the door is opened.
• Radio-operated doorbells transmit signals briefly or, if defective, often
continuously. In such cases, the transmitter is located in the doorbell
button.
• Headphones or other systems in households can also transmit signals
via radio.
• As a test, you can deactivate the various systems and see what
happens. A simple change of location often helps a lot.
• Weak battery? Replace it.
Can I operate several shutters simultaneously via a 1-channel
remote control?
• This is possible in the same room, but not advisable as both or all
shutters are always operated at the same time. The individual control
of a single shutter is not possible. As a general rule, only use a 6-
channel remote control (accessory). This is equipped with a
mechanism whereby all the shutters can be automatically controlled
either together or individually, as required.
FAQs AND TROUBLESHOOTING (MOTOR)
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.
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.
