Banner EZ-SCREEN­ Safety Light Curtain Systems - Manual (Page 42)

Receiver: A bi-color red/green Beam Status indicator for each beam shows
whether that beam is aligned and clear with a strong signal, clear but with a weak
signal, or is blocked and/or misaligned. A yellow Reset indicator shows when the
system is in Run mode or is waiting for a reset. A bi-color red/green Status
indicator shows when the OSSD outputs are ON (green) or OFF (red), or the
system is in lockout mode (flashing red). A 7-segment diagnostic display
indicates the receiver’s Trip (–) or Latch (L) configuration setting and displays a
specific error code when the receiver is in lockout. The 7-segment display also
momentarily indicates the scan code setting at power-up or when changed.
NOTE: If beam 1 is blocked, all other Beam Status indicators will be OFF, because
beam 1 provides the synchronization signal for all the beams.
