EZ-SCREEN LS Safety Light Screen
p/n 190579 Rev A 2
Error Codes (with flashing RED status indicator)
•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)
Possible corrective action(s):
•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.
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.
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.
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).
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):
