What to do if...?
Problem
Remedy
The roller shutter curtain is raised unevenly or not at all.
Stops have broken off or one or several attachments are
broken. Repair system; delete limit positions, then reprogram
limit positions.
Tubular drive overruns the limit position or does not reach the
set limit position.
Repair system; delete limit positions, then reprogram limit posi-
tions.
Check electrical installation, remove external devices, delete
limit positions and then reset limit positions.
Tubular drive stops arbitrarily; cannot be restarted in the same
direction.
Tubular drive has detected an increase in load. Briefly run the
curtain in the opposite direction, then continue in the desired
direction.
Tubular drive is overloaded. Use a higher-torque tubular drive.
Delete limit positions, then reprogram limit positions.
Tubular drive does not run in the right direction.
Tubular drive is overheated. The tubular drive is operational
again after a few minutes.
Tubular drive is faulty (does not run even after standing still for
a long period of time). Replace the tubular drive.
Clear and remove the obstruction and set the drive in the direc-
tion required.
Check the electrical connection.
During the programming run, the drive stops short of the limit
position to be programmed.
For safety reasons, the drive reacts sensitively to sluggishness
during the programming run, in order to prevent damage.
Briefly run curtain DOWN and subsequently UP until you reach
the upper limit position.
Ventilation slots of the roller shutter do not close fully.
Delete the limit positions (see Deleting limit positions) and then
set the limit positions as per "to lower point" (see chapter Set-
ting the limit positions); in this case, set the lower limit position
first (lower point) followed by the upper limit position.
When opening, the drive stops short of the programmed limit
position.
Upper anti-freeze mechanism is activated.
The roller shutter only opens to the upper stop once every
32 times.
Deactivate the upper anti-freeze mechanism.
