Cam-driven, magnet-released ratchets sometimes fail to release and operate even though properly requested. Further, ratchets sometimes fail to return once they do release. If other operations, controlled by the ratchet, are conditioned upon the ratchet release and return to normal rest position, failure to release or return to rest position will cause malfunctions.
