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.

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.

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.

Excessive Noise
Error – Cascade
Input
This error can occur due to excessive levels of electrical noise.
Possible corrective action(s):
• Cycle power (see 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) 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).
