What to do if...?
Problem Cause Remedy
The roller shutter curtain is raised un-
evenly or not at all. 1. One or more attachments have
broken off.
2. Lath has broken off.
Repair system; then re-program limit po-
sitions.
Tubular drive overruns the limit position or
does not reach the set limit position. A short circuit caused by dampness. Repair electrical installation; re-program
limit positions.
External devices are connected to the
connecting cables of the tubular drive. Check electrical installation; remove any
external devices; re-program limit posi-
tions.
Due to long cable, L1 and N connections
have been reversed. Change around L1 and N (N = blue, L1 =
black/brown); re-program limit positions.
Stops have broken off or one or more at-
tachments are broken. Repair system; reset tubular drive, then
re-program limit positions
Tubular drive stops arbitrarily; cannot be
restarted in the same direction. Tubular drive is overloaded. Use a more powerful tubular drive.
System keeps sticking; too much friction. Ensure that the system runs smoothly.
Installation of a tubular drive with previ-
ously programmed limit positions. Delete and reset the limit positions.
Tubular drive does not run in the right dir-
ection. Tubular drive is overheated. The tubular drive is operational again
after a few minutes.
Tubular drive is faulty (does not work
even after standing still for a long period
of time). Replace the tubular drive; press the reset
button on the programming unit. No click-
ing sound (emergency program); tubular
drive can be opened and closed for dis-
mounting using the programming unit.
Tubular drive switched off the last time it
went in that direction because of a block-
age. Clear and remove the blockage and set
the drive in the direction required.
Electrical connection faulty. Check the electrical connection.
When you attempt to set the limit posi-
tions using the programming unit, this
does not work. The limit positions were previously set us-
ing the switches. Set both switches to the delete setting.
Execute a short drive command.
Set both switches to the programming
setting simultaneously.
Re-set the limit positions using the pro-
gramming unit.
When you attempt to set the limit posi-
tions using the switches, this does not
work. The limit positions have been reached a
number of times. Set both switches to the delete setting.
Execute a short drive command.
Re-set the limit positions.
During the programming run, the drive
stops short of the limit position to be pro-
grammed. For safety reasons, the drive reacts sens-
itively to sluggishness during the pro-
gramming run, in order to prevent dam-
age. Briefly run curtain DOWN and sub-
sequently UP until you reach the upper
limit position.
Ventilation slots of the roller shutter do
not close fully. Sluggish running of the roller shutter near
the lower stop and setting of the "lower
stop" limit position. Delete the limit positions and set the limit
positions as per "to lower point". In this
case, first program the lower limit position
(lower point) and secondly the upper limit
position.
