Error Descriptions and Causes Appropriate Action
Excessive Noise Error – Reset Interface
This error occurs due to excessive levels of
electrical noise.
Perform a reset per " Reset Procedures " on page 55 .
If the error clears, perform a Daily Checkout procedure (per " Shift/Daily Checkout "
on page 67 ) and if OK, resume operation. If the System fails the Daily Checkout pro-
cedure, 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 Check-
out procedure ( "Initial Checkout Procedure" on page 35 ).
If the error clears, check for sources of electrical noise (see "Electrical and Optical
Noise " on page 89 ).
If the error continues, replace the receiver.
Excessive Noise Error – EDM Interface
This error occurs due to excessive levels of
electrical noise.
Excessive Noise Error – Cascade Input
This error occurs due to excessive levels of
electrical noise.
(flashing)
Cascade Input Simultaneity
Operation of channels A and B mismatch >
3 seconds.
Check operation of Channel A and Channel B of cascade input.
Cycle power or cycle the input. See
"Emergency Stop Buttons and Rope/Cable
Pulls " on page 79 and "Interlock Switches in Cascaded Systems" on page 80 .
The emitter has only a 1-digit display. Two-digit codes are displayed sequentially.

then
Emitter Error
This error can occur either due to
excessive electrical noise or due to
an internal failure.
Reset the emitter per " Reset Procedures " on page 55 .
If the error clears, perform the daily checkout procedure (per EZ-SCREEN Checkout Pro-
cedures: 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
"Generic Wiring Diagrams" on
page 47 ).
If the sensor has a good earth ground connection, check for electrical noise (see "Electrical
and Optical Noise " on page 89 ).
If the error persists, replace the emitter.
then
Excessive Noise Error
This error can occur due to exces-
sive electrical noise.
Reset the emitter per " Reset Procedures " on page 55 .
If the error clears, perform the daily checkout procedure (per EZ-SCREEN Checkout Pro-
cedures: 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
"Generic Wiring Diagrams" on
page 47 ).
If the sensor has a good earth ground connection, check for electrical noise (see "Electrical
and Optical Noise " on page 89 ).
If the error persists, replace the emitter.
If the System cannot be aligned or it will not go to a Green/Clear condition, the emitter’s TEST input may be open. When this
occurs, the receiver Reset indicator is amber, all Zone indicators will be red and the system Status LED will be red. The 3-
digit display shows a numerical value equal to one less than the total number of beams. For example, if an array has 50
beams total, the display would show 49 and the emitter’s Status indicator flashes green. See " Status Indicators " on page
56 and "Troubleshooting" on page 85 . (On a 10-beam system, Zone 1 indicator is green and all others are red.)
Opening a switch or relay contacts connected to the TEST1 and TEST2 connections of the emitter, or supplying a voltage of
less than 3 V dc to TEST1 only, simulates a Blocked condition, for testing purposes.
To verify proper operation, measure the voltage between TEST1 (pin 4, black) and dc COM (pin 3, blue) of the emitter:
If the voltage is 10 V dc to 30 V dc, the emitter should be in Run mode and beam scanning should be occurring. If the
emitter is not in Run mode:
Check the +24 V dc (pin 1, brown) to verify proper supply voltage. If the supply voltage is not within the rated
supply voltage specifications, correct the supply voltage and recheck the emitter operation.
