Emitter Resets
In the rare occurrence that an emitter requires a reset, power the sensor down, then power it up. Emitter resets are needed only if a
Lockout occurs.
Status Indicators
The emitter has one LED and the receiver has four, to provide an ongoing indication of light screen and system operation. In normal
operation, the status indicators are as described below and as shown in
Figure 16. Status Indicator behavior during the trip test on page
45. Additional LED condition combinations indicate errors or faults; refer to Troubleshooting and Lockout Conditions on page 47.
Emitter
Power/Fault Indicator: Green LED indicates whether power is applied or a Fault condition exists.

Receiver
Alignment Indicators
Two Yellow Alignment indicators (Top and Bottom) tell the alignment status of the top and bottom beams in the light screen. This is
helpful for sensor alignment: first align the Top beam (the sync beam), then the bottom beam. The Alignment indicators also flash togeth-
er to indicate a manual reset is needed (Latch output models).
Receiver
Indicator Color ON Flashing OFF
Top Alignment Yellow Top (sync) beam is
aligned and clear (Both together) System is
aligned; waiting for man-
ual reset (Latch models) Top (sync) beam is
blocked or misaligned

and clear Bottom beam is blocked
or misaligned; sync
beam possibly blocked
Status Indicators
Two Status indicators (Blocked and Clear) work together to indicate the status of the light screen.
