Description
1
Status indicator (red/green)—shows System status:
•
Outputs are ON or OFF (green ON or red ON)
•
The System is in Lockout condition (flashing red)

Zone indicators (red/green/yellow)—each shows the status of approximately 1/3 of the
total beams:
•
Aligned and clear (green ON)
•
Blocked and/or misaligned (red ON)
•
All beams are clear, but one or more beams have weak beam strength
(yellow ON)
The Zone 1 indicator, at the bottom of this view, represents the 1/3 of the unit that is
toward the RD end of the unit. The Zone 2 indicator is in the middle and represents
the middle 1/3 of the unit. The Zone 3 indicator is at the top and represents the 1/3 of
the unit closest to the end cap.

Zone 1 Indicator—indicates beam synchronization status
3.5.1 Trip Output
The System is configured for Trip Output which allows the System to enter Run mode automatically. Other measures must
be taken to prevent a pass-through hazard; see
Reducing or Eliminating Pass-Through Hazards
on page 18 and the
warning below for more information.
The OSSD outputs turn ON after power is applied, and the receiver passes its internal self-test/synchronization and
recognizes that all beams are clear. The Trip Output also automatically resets after all beams are cleared.
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.
3.5.2 Scan Code Configuration
Use the scan code to allow operation of multiple pairs of emitters and receivers in close proximity without the effects of
crosstalk.
The emitter and receiver may be configured to use one of two scan codes (1 or 2); a receiver recognizes light only from an
on page 28). Both the emitter and its corresponding receiver must have the same setting.
The default setting is Scan Code 1.
