5-3. Remote Interlock Connector

This connector functions as safety device for the projector. The contacts are normally closed. When an abnormality occurs, the
contacts open to immediately stop the projector (interlock state) (shipped with a shorting wire installed). By replacing the shorting
wire with wiring and attaching it to the contacts, the projector can be immediately stopped remotely when an abnormality occurs in
the projector.
Follow the following procedure to recover from the interlock state.
