Multiple errors are signalled by a 2-second pause between signals.
Should the encoder (obstacle detection) activates while closing, the controller will reverse the direction
and slowly open until the laef reaches its fully opened position. Auto Close function will be deactivated
until a further command pulse is given. In case of 5 consecutive safety interventions the controller will
progressively increase the Auto Close delay. Once the closing has been succesfully achieved, the Auto
