First of all, it must be said that the most common reason for the motor to stop is not the timer, but the motor itself or the mechanics of the roller shutter.
Info about this also under The tubular motor stops between the end points for no apparent reason?
Nevertheless, the tubular motor actuator can also lead to the error pattern.
The tubular motor actuator has a switchable blocking detection for tubular motors with mechanically adjustable limit switches.
This function is deactivated at the factory, but can be switched on in conjunction with the HomePilot.
If you use a tubular motor with electronic end point adjustment, this function cannot be used . With these motors, the blockage detection causes the motor to stop again and again.
Switch off the blocking detection via the HomePilot.
