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 connection
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 programme); tu-
bular drive can be opened and closed for
dismounting 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.
Tubular drive only runs for approx. 5 secs. Tubular drive is in error mode.
Reset the limit positions or replace the tu-
bular drive.
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.
Set the limit positions once again with the
programming unit.
When you attempt to set the limit posi-
tions using the switches, this does not
work.
The limit positions have been reached
more than 16 times.
Set both switches to the delete setting.
Execute a short drive command.
Set the limit positions again.
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 unsmooth running during the
programming run, in order to prevent
damage.
Briefly run curtain DOWN and sub-
sequently UP until you reach the upper
limit position.
