Problem:
When opening, the drive stops short of the programmed limit position.
Remedy:
Tubular drive overruns the limit position or stops short of the set limit position.
Remedy:
- Check electrical installation, remove external devices, delete limit positions and then reset limit positions.
- Repair electrical installation and re-program limit positions.
- Stops have broken off or one or several attachments are broken. Repair system; reset tubular drive, then re-program limit positions.

____________________________________________
Tubular drive does not run in the right direction.
Remedy:
- 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 switch in the desired direction. Check the electrical connection.

Problem:
During the programming run, the drive stops short of the limit position to be programmed.
Remedy:
- For safety reasons, the drive reacts sensitively to sluggishness during the programming run, in order to prevent damage. Briefly run roller shutter DOWN and then UP until you reach the upper limit position.
____________________________________________
Problem:
Ventilation slots of the roller shutter do not close fully.
Remedy:
- Delete the limit positions (see Deleting limit positions) and then set the limit positions as per to lower point (see chapter Setting the limit positions); in this case, set the lower limit position first (lower point) followed by the upper limit position.
____________________________________________
Problem:
When opening, the drive stops short of the programmed limit position.
Remedy:
- 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.
