2.11 Secondary Entrapment Protection for Master / Slave Configuration
Secondary entrapment protection for slide gate operators connected in a master / slave configuration
will require three sets of photo-beams to insure protection.
One photo-beam is directed across the roadway and connected to the CLOSE photo-beam
input on the auxiliary terminal strip of both the master and slave operator. This photo-beam is
active in the close direction only and will not affect the movement of the gates while the gates
are opening.
Two photo-beams are required to protect the open direction of the gates - one for the master
operator and one for the slave operator. These photo-beams are connected to the OPEN
photo-beam input on the auxiliary terminal strip in their respective operator. These photo-
beams are active in the open direction only. If a beam is interrupted while the gate(s) are in
the open cycle, only the gate that is controlled by the interrupted beam will stop, the other
gate will continue in the open direction.
