Safety circuit for pneumatically operated passenger door on safety vehicle stops door closing process early if lever is pivoted away from end switch before door has reached end sensor

摘要

The safety circuit has a lever (6) with an associated end sensor actuated when the lever is in its stop position (2). The door closing process is only interrupted early by a timing relay if the lever is pivoted away from its end switch before the passenger's door (101) has reached its end sensor (a2).
