9.2 Remote Test Input
EZ-SCREEN LPM emitters provide a Test function, selectable by DIP switch. An external switch, typically a normally open
contact, held closed, is connected between the emitter and 24V dc. Opening the switch “turns off” the emitter, simulating
an interruption of one or more light beams. This function may be useful for EZ-SCREEN LPM setup and to verify machine
control circuit operation.
9.3 Selectable Trip/Latch Outputs
The setting for Trip or Latch Output determines whether the System will enter RUN mode automatically after power-up, or if
it will require a manual reset first. If the System is set for Trip Output, other measures must be taken to prevent a pass-
through hazard.
• If Trip Output is selected, the OSSD outputs will turn ON after power is applied and the receiver passes its internal
self-test/synchronization and recognizes that all beams are clear. The OSSD outputs will also turn on after all beams
are cleared following a blocked beam.
• If Latch Output is selected, the EZ-SCREEN LPM requires a manual reset for the OSSD outputs to turn ON,
whenever power is applied and all beams are clear, or following a blocked beam.
WARNING:
• Use of automatic (trip) or manual (latch) start/restart
• Failure to follow these instructions could result in a serious injury or death.
• Applying power to the Banner device, clearing the defined area, or resetting a latch condition
must not initiate dangerous machine motion. Design the machine control circuitry so that one or
more initiation devices must be engaged to start the machine (a conscious act), in addition to the
Banner device going into Run mode.
