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);

Flashing RED (Lockout, in conjunction with displayed error code, see below)

Lockout condition: Indicated by the sensor’s status LED

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).

Error Codes (with flashing RED status indicator)

Code Problem Solution

Error is caused by:

1 Output Error

?

?

?

?

?

?

one or both outputs being shorted to a power supply (high or low)

by shorting OSSD 1 to OSSD 2

by an overload (greater than 0.5 A)

Disconnect the OSSD loads and cycle power to the receiver.

If the error clears, the problem is in the OSSD load(s) or in the load wiring.

If the error continues with no load connected, replace the receiver.

Possible corrective action(s):

4 Receiver Error

This error occurs because of either excessive electrical noise or an internal failure.

This error can also occur when the remote fixed blanking RUN/PROGRAM switch is

in the PROGRAM position during power-up.

Possible corrective action(s):

?

?

Cycle power, See Recovery Procedures in the instruction manual.

If the error clears, perform a Daily Checkout procedure (per EZ-SCREEN

Checkout Procedures: Shift and Daily Checkout Procedure; Daily Checkout

Card) and if the System checks out, resume operation. If the System fails

the Daily Checkout procedure, replace the receiver.

If the error continues, check the ground connection (pin 7).

If the sensor has a good earth ground connection to pin 7, perform the Initial

Checkout procedure (per Initial Checkout Procedure in the instruction

manual).

If the error clears, check the external connections and configuration settings.

If remote fixed blanking is used, ensure RUN/PROGRAM is in the RUN

position and cycle power.

If the error continues, replace the receiver.

?

7 Receiver Error

This error can be caused by intermittent connections between cascaded receivers or

excessive electrical noise.

Possible corrective action(s):

?

?

?

Verify the cordset connections between the cascaded receivers.

If the error continues, replace the cordset(s).

If the error still continues, replace the receiver with the error code.

8 EDM Error

This error can occur when the EDM input is open at power up or if the signal fails to

respond within 250 ms of the OSSDs changing state (On to Off).

Possible corrective action(s):

?

?

Verify that the EDM wiring is correct and that the external devices meet the

requirements described in Machine Primary Control Elements and EDM

Input in the instruction manual

If the error continues, remove power to the guarded machine, disconnect the

OSSD loads, disconnect the EDM input signals, configure EDM for No

Monitoring (per Machine Primary Control Elements and EDM Input in the

instruction manual) and conduct the Initial Checkout procedure

If the error clears, the problem is in the External Device contacts or wiring,

or is a response-time problem of the external devices. Verify that the EDM

wiring is correct and that the external devices meet the requirements

described in Machine Primary Control Elements and EDM Input in the

instruction manual.

If the error continues, check for noise on the EDM inputs (see Electrical and

Optical Noise in the instruction manual).

?

1 0 Fixed Blanking

Error

This error occurs when beam(s) that have been blanked (programmed to ignore a

fixed object) become clear when the object is removed or moved.

Possible corrective action(s):

p/n 190579 Rev A 2

EZ-SCREEN LS Safety Light Screen

Code Problem Solution

?

?

Reposition the object and cycle power.

Re-program (teach) the fixed blanked object(s), see Remote Fixed Blanking

Programming Procedures in the instruction manual.

1 2 Programming

Timeout Error

This error occurs when the Fixed Blanking programming mode (teach) exceeds the

ten minute limit.

Possible corrective action(s):

? Re-program (teach) the fixed blanked object(s), see Remote Fixed Blanking

Programming Procedures in the instruction manual.

1 3 Cascade Error

This error occurs when a cascade receiver is not terminated properly or if the EDM

wiring to a cascade receiver is not terminated properly

Possible corrective action(s):

?

?

?

?

Verify that the last receiver in the cascade is terminated properly (see

Cascadeable EZ-SCREEN LS in the instruction manual).

Verify that the EDM wiring is correct.

Verify the cordset connections between cascaded receivers.

If the error continues, replace the receiver.

NOTE: In a cascaded system, all receivers are connected together, and all emitters

are connected together.

6 4 Excessive Noise

This error can occur due to excessive levels of electrical noise.

Error – Cascade

Possible corrective action(s):

If the error clears, perform the daily checkout procedure (per EZ-SCREEN

Checkout Procedures: Shift and Daily Checkout Procedure; Daily Checkout

Card) and if the System checks out, resume operation. If the System fails

the Daily Checkout procedure, replace the receiver.

If the error continues, check the ground connection (pin 7).

If the sensor has a good earth ground connection to pin 7, perform the Initial

Checkout procedure (Trip Test) in the instruction manual.

If the error clears, check for sources of electrical noise (see Electrical and

Optical Noise in the instruction manual).

If the error continues, replace the receiver.

H Cascade Input

Simultaneity

Operation of channels A and B mismatch > 3 seconds.

Possible corrective action(s):

?

?

Check operation of Channel A and Channel B of cascade input.

Cycle power or cycle the input. See Emergency Stop Buttons in Cascaded

Systems and Interlock Switches in Cascaded Systems in the instruction

manual.

Emitter

Status Indicators

? A single bi-color red/green Status indicator shows when the emitter is in RUN mode (GREEN transmitting),

or the System is in Lockout status (flashing RED).

Emitter LED Problem - This is not an error that would immediately result in a lockout. This

indication can occur due to a potential problem with an LED and is provided as an early warning

indicator.

Error Code (with flashing RED status indicator)

Code Problem Solution

This error can occur if the ID Input (pin 3, Orange) is not connected to +24 V dc.

2 5 Emitter Error

Excessive electrical noise or an internal failure can also cause this error.

Possible corrective action(s):

?

?

?

Verify that the ID Input (ID_in) wiring is connected to +24 V dc. See Generic

Wiring Diagram—5-pin and 8-pin Emitter in the instruction manual

Cycle the power to the emitter per Recovery Procedures in the instruction

manual

If the error clears, perform the daily checkout procedure (per EZ-SCREEN

Checkout Procedures: Shift and Daily Checkout Procedure; Daily Checkout

Card). If the System checks out, resume operation. If the System fails,

replace the emitter

If the error continues, check the ground connection (see Cordsets in the

instruction manual)

If the sensor has a good earth ground connection, check for electrical noise

(see Electrical and Optical Noise in the instruction manual)

If the error persists, replace the emitter
