Receiver Indicators
Emitter Indicators
System Operation, Diagnostics and Troubleshooting
Both emitter and receiver feature 7-segment Diagnostic Displays and individual Status LEDs to provide continuous
indication of operating status, configuration and error conditions. Active Alignment (Segment) Indicators provide for
beam block information and easier installation.
Run Mode: Indicated by the sensor’s status LEDs:
• Solid RED (Blocked condition, OSSDs OFF),
• Solid GREEN (Defined area clear, OSSDs ON; Emitter transmitting)
• Flashing GREEN (Blanking enabled, Defined area clear, OSSDs ON);
Lockout condition: Indicated by the sensor’s status LED
• Flashing RED (Lockout, in conjunction with displayed error code, see below)
See EZ-SCREEN LS instruction manual p/n
179480
for complete installation, operational, and troubleshooting
information, and applicable cautions and warnings.
Receiver
Status Indicators
• A single red/green Status indicator shows when the OSSD outputs are ON (GREEN) or OFF (RED),
blanking is enabled (flashing GREEN), or the System is in Lockout status (flashing RED).
• An amber RUN Mode indicator shows when the system is operational (not in lockout).
Diagnostic Display
(Multiple-digit codes are sequential, followed by a pause)
Operational Codes (RUN Mode, amber LED is ON)
Code
Description
-
RUN Mode (single dash)
C 1
Sensor configured for Scan code 1
C 2
Sensor configured for Scan Code 2
Note: both emitter and receiver must be configured for the same Scan Code
C H 1
The first sensing beam (CH1 synchronization beam) at the display end of sensor is blocked (must
remain clear) or the receiver Scan Code does not match the emitter Scan Code.
n n n
The number of blocked beams.

Summary

System Operation and Diagnostics

Receiver Status Indicators

Shows OSSD outputs ON (GREEN) or OFF (RED), blanking enabled, or system in Lockout status.

Receiver Diagnostic Display

Multiple-digit codes are sequential, followed by a pause for status indication.

Receiver Operational Codes

Codes indicating system status when the amber RUN Mode LED is ON.

Error Codes and Troubleshooting

Output Error Troubleshooting

Error caused by shorted outputs, OSSD short, or overload.

Receiver Error Troubleshooting

Occurs due to electrical noise, internal failure, or incorrect blanking switch setting.

EDM Error Troubleshooting

Occurs when EDM input is open at power up or fails to respond within 250 ms.

Fixed Blanking Error Troubleshooting

Occurs when blanked beams become clear after object removal or movement.

Programming Timeout Error

Fixed Blanking programming mode (teach) exceeds the ten minute limit.

Cascade Error Troubleshooting

Cascade receiver or EDM wiring not terminated properly in a cascaded system.

Excessive Noise Error - Cascade Input

Occurs due to excessive levels of electrical noise in a cascaded system.

Cascade Input Simultaneity Error

Operation of channels A and B mismatch by more than 3 seconds.

Emitter Status and Diagnostics

Emitter Status Indicators

Shows emitter in RUN mode (GREEN transmitting) or Lockout status (flashing RED).

Emitter Diagnostic Display

Multiple-digit codes are sequential, followed by a pause for status indication.

Emitter Operational Codes

Codes indicating system status when the amber RUN Mode LED is ON.

Emitter Error Codes

Emitter LED Problem Warning

Early warning for potential LED problem, not immediate lockout.

Emitter Error Troubleshooting

Occurs if ID Input is not connected, due to noise, or internal failure.
