If the end points are set correctly on the RolloTube S-line DuoFern, but the motor then stops several times between the end points, one of the following points may be the cause.
1. adapter has slipped off the magnetic ring:
The tube motor checks the revolutions of the motor and the shaft during travel.
Possible cause:
- The adapter may have slipped off the magnetic ring on the drive head. Check that the adapter sits flush in front of the drive head and is fully inserted in the winding shaft (see instructions). The motor must always be pushed completely into the winding shaft. The length compensation or correction is set via the position of the roller capsule.
- If the motor has been adapted to a different shaft size, the previous driver AND the adapter must be removed and replaced by the new ones.
The obstacle detection responds although no obstacle is present.
The RolloTube S-line DuoFern has a powerless obstacle detection. If during the descent it is detected that the motor is turning, but the shaft is stationary, the motor switches off.
Possible cause:
- Roller shutter too light: If the roller shutter is very light and, in addition, the guidance is not ideal, it may happen that the roller shutter does not "slide down" by itself
Solution:
- Check the roller shutter mechanism, roller shutter guide, inlet funnel and look for possible damage.
- Weight down the lowest roller shutter slat (for example, with a flat iron).
- Set the upper end point a few centimeters lower, so that after starting the motor already more weight pulls on the shutter curtain.
- The driver of the motor can be mounted without freewheeling in order to bypass the obstacle detection system. For this purpose, the motor must be removed and the driver can be disassembled and reassembled without freewheeling.
- If you control the RolloTube S-line via the HomePilot or the Bridge, you can completely deactivate the obstacle detection.
- Possibly the winding shaft is installed very tightly.
The motor works with a free-wheeling driver. The motor is not rigidly connected to the shaft, but must be able to rotate slightly back and forth by approx. 20°. If the shaft has been installed too tightly, the freewheel may be blocked as a result.
Solution:
- Loosen the roller capsule and insert it approx. 2-3 mm further into the winding shaft and fix the capsule again with a screw.
3. thermal protection:
If the motor has been operated several times within a short time, the motor may have switched off via the thermal protection. The motor has a short operation (KB) of 4 minutes.
Solution:
- Allow the motor to cool down for approximately 30 minutes.
4. the screen door protection was activated via the HomePilot.
This makes the motor in the upper area more sensitive or switches off earlier. If the shutter does not unwind cleanly immediately, the motor recognizes this as an open screen door and switches off.
Solution:
- Weight down the lowest shutter slat (for example, with a flat iron).
- If necessary, deactivate the fly screen door protection via the HomePilot.
Incorrectly calibrated:
In some cases, the motor may have calibrated itself incorrectly.
Solution:
- Perform a reset of the motor. Reset instructions.
