Diagnostic Display Error Description Cause of Error and Appropriate Action
DIP Switch Error
This error can be caused by incorrect DIP switch
settings or by changes to the DIP switch settings
when the system is ON.
• Verify that the DIP switch settings are valid (per
System
Configuration Settings
(p. 64)). Make any corrections necessary
and perform a receiver reset.
• If the error occurred due to a change of the DIP switch settings
while the System was in Run mode, verify the switch settings and
perform a receiver reset to resume operation with the new switch
settings and modified System configuration.
• If the error continues, replace the receiver.
EDM Error
This error can occur due to EDM input signal failing
to respond within 250 ms of the OSSDs changing
state (ON to OFF).
• Verify that the EDM wiring is correct and that the external devices
meet the requirements described in
Machine Primary Control
Elements and EDM Input
(p. 44).
• 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
(p. 44)) and conduct the Initial Checkout
procedure in
Remote Test Input
(p. 68).
• 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
(p. 44).
• If the error continues, check for noise on the EDM inputs (see
Electrical and Optical Noise
(p. 80)).
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.
• Reposition the object and perform a key reset (or cycle power).
•
Re-program (teach) the fixed blanked object(s), see
Fixed Blanking
(p. 40).
Programming Timeout Error
This error occurs when the Fixed Blanking
programming mode (teach) or Mute Configuration
programming modes exceeds the ten-minute limit.
• Re-program (teach) the fixed blanked object(s), see
Fixed Blanking
(p. 40).
• Re-program the mute configuration, see
Muting Functions
(p. 53)
and
Mute Configuration
(p. 38).
Muting Device Input Error • Verify the Muting Device Input(s) are not shorted together or to
another source of power or ground.
Bypass/Override Error • Verify the Override Input(s) are not active upon power-up or when
exiting a lockout condition.
• Verify the Override Input(s) are not active when muting ends.
Mute Lamp Error • Check/replace the lamp as a short or open has been detected in
the mute lamp circuit.
•
Verify the DIP switch setting is as desired.
Excessive Noise Error – Reset Interface
This error can occur due to excessive levels of
electrical noise.
• Perform a reset per
Reset Procedures
(p. 76).
• If the error clears, perform the daily checkout procedure (per EZ-
SCREEN Checkout Procedures: Shift and Daily Checkout
Procedure; Daily Checkout Card) and if OK, 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
(p. 41)).
• If the error clears, check for sources of electrical noise (see
Electrical and Optical Noise
(p. 80)).
• If the error continues, replace the receiver.
Excessive Noise Error – EDM Interface
This error can occur due to excessive levels of
electrical noise.

Advanced Diagnostics for the purpose of factory
troubleshooting and repair; not intended for field
troubleshooting.
If advanced diagnostic codes are inadvertently displayed, toggle the Invert
Display DIP switch (to the opposite state and back, within 1 second) to
return to the standard error code display.
