The RolloTron stops several times when closing and opening the roller shutter for no visible reason. Why?

All RolloTron devices have integrated obstacle detection and motor monitoring. Obstacles are detected by the devices by means of belt monitoring. The belt runs past a small deflection roller in the devices and turns it. There is a magnet in this roller, which is detected by a sensor. If the roller does not rotate for any reason, the motor stops.

For this reason, RolloTron devices CANNOT be operated without a belt.

The motor is monitored electronically. If the RolloTron is under extreme load, e.g., due to a blocked shutter, the electronics detect this condition and switch off the motor. In this case, check whether the roller shutter moves smoothly and remove any blockages if necessary.
