All RolloTron devices have integrated obstacle detection and motor monitoring. Obstacles are detected by the devices using a belt monitoring system. In the devices, the belt runs past a small deflection roller and rotates 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.
RolloTron devices can NOT be operated without a belt for this reason.
The motor is monitored electronically. If the RolloTron is under extreme load, e.g. due to a blocked roller 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.
The RolloTron stops several times when closing and opening the shutter without any visible reason, why?
