What to do if...?
Problem Cause Remedy
Tubular drive overruns
the end limit or does
not reach the set end
limit.. 1. A short circuit caused by dampness. 1. Investigate source, dry out the system and
reprogramme.
2. External devices are connected to the power
leads of the tubular drive.
2. Check electrical installation, remove ex-
ternal device if connected, reprogramme
system.
3. L1 and N connection have been reversed. 3. Exchange L1 and N (N = blue, L1 = black/
brown), reset the end limits.
4. End stops have become detached or one or
more suspension devices have broken.
4. Repair system; reset tubular drive, then
reset the end limits.
The tubular drive does
not retract after setting
the extended limit stop. The tubular drive has been accidentally extend-
ed further and switches off automatically.
Both end limits have now been set in the tubular
drive. Delete the limit stops, reset the outer end limit
and immediately retract.
Tubular drive stops
arbitrarily, impossible
for it to move further in
the same direction. 1. Tubular drive is overloaded. 1. Use a more powerful tubular drive.
2. Sunshade system keeps jamming, friction is
too high.
2. Ensure that the sunshade system runs
smoothly.
3. Fitting a tubular drive which has end limits
already programmed.
3. Delete the end limits and reinstall them.
Tubular drive does not
run in the direction
required. 1. Tubular drive is overheated. 1. The tubular drive is operational again after a
few minutes.
2. Tubular drive is faulty (does not work even
after standing still for a long period of time).
2. Replace the drive; carry out RESET with the
programming pushbutton. No click may be
heard (emergency programme), tubular
drive can be moved up and down using the
setting controls for the purpose of dismoun-
ting the drive.
3. Tubular drive switched off when it encounte-
red an obstacle the last time it moved in the
same direction.
3. Move the curtain or canopy away from the
obstacle, remove the obstacle and set the
drive to move in the direction required.
4. Electrical connection faulty. 4. Check the electrical connection.
Tubular drive only runs
for approx. 5 secs. Tubular drive is in error mode (obstacle recog-
nition malfunctioning). Reset the end limits or replace the tubular drive.
When you attempt to
set the end limits using
the setting controls,
this does not work. The end limits have already been set using the
switches. Move both switches to the reset position.
Press the control command briefly.
Move both switches to the programming posi-
tion simultaneously.
Reset the end limits using the setting controls.
When you attempt to
set the end limits using
the switches, this does
not work. The end limits have been reached more than 16
times. Move both switches to the reset position.
Press the control command briefly.
Reset the end limits.
Tubular drives switches
off automatically be-
fore programming the
desired 1. Final posi-
tion (final position of
extention). Drive has recognized an increase in torque. 1. Drive past this position.
2. Push the Reset-button while being at this
position.
