product manual:

       The anti-bias switch is used for belt deviation detection and can be fixed on the top or bottom of the conveyor longitudinal beam. It is usually installed at the ends of the belt 0.3 to 2 meters away from the head or tail roller. After the belt runs off, the action arm is forced to deviate and the alarm micro switch is activated. If you continue to deviate from the stop contact and touch another set of contacts, the conveyor will stop mechanically.
