The driving system is equipped with motoreducer with installed Hall sensor, transmitting the information to the electronic controller about the current operation of the fuel, that is its revolutions and direction. If the endless screw is jammed the controller automatically switches the direction of revolutions (worm is withdrawn) for several seconds and then it attempts to overcome the obstacle. If the process is not successful then another two attempts will be undertaken. But, for each attempt, the motoreducer withdraws the worm two times longer. The solution eliminates the problem of troublesome replacement of security pin if the feeder is blocked.
