Error Descriptions and Causes Appropriate Action
Receiver Error
This error occurs due to excessive electri-
cal noise or an internal failure.
Reset the receiver per "Emitter and Receiver Reset" on page 85 .
If the error clears, perform a Daily Checkout procedure (per EZ-SCREEN Checkout
Procedures: Shift and Daily Checkout Procedure; Daily Checkout Card). If the Sys-
tem checks out, resume operation. If the System fails, 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 (per
"Initial Checkout Procedure" on page 35 ).
If the error clears, check the external connections and configuration settings.
If the error persists, replace the receiver.
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. 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 1 Error
This error can occur when the EDM 1 input
signal fails 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 de-
scribed in
"Machine Primary Control Elements (MPCE) and External Device Monitoring (EDM)
Input" on page 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 " Ma-
chine Primary Control Elements (MPCE) and External Device Monitoring (EDM) In-
put" on page 44 ), and conduct the Initial Checkout procedure in "Initial Checkout
Procedure" on page 35 .
If the error clears, the problem is in the External Device contacts or wiring, or is a re-
sponse-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 (MPCE) and External Device Monitoring (EDM) Input" on page 44 .
If the error continues, check for noise on the EDM inputs (see "Electrical and Optical
Noise " on page 89 ).
EDM 2 Error
The EDM 2 configuration is not valid.
Verify that the EDM wiring is correct and that the external devices meet the require-
ments described in
"Machine Primary Control Elements (MPCE) and External Device
Monitoring (EDM) Input" on page 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 " Ma-
chine Primary Control Elements (MPCE) and External Device Monitoring (EDM) In-
put" on page 44 ), and conduct the Initial Checkout procedure (see "Initial Checkout
Procedure" on page 35 ).
If the error clears, the problem is in the External Device contacts or wiring, or is a re-
sponse-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 (MPCE) and External Device Monitoring (EDM) Input" on page 44 .
If the error continues, check for noise on the EDM inputs (see "Electrical and Optical
Noise " on page 89 ).
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 " on page 39 .
Programming Timeout Error
This error occurs when the Fixed Blanking
programming mode (teach) exceeds the
ten-minute limit.
Re-program (teach) the fixed blanked object(s), see " Fixed Blanking " on page 39 .
Cascade Configuration Error
This error occurs when the configuration
sequence is incorrectly followed,
receiver(s) 2, 3 or 4 are configured, or re-
ceiver 1 is moved to a different position in
the cascade.
The CSSI Input channel(s) are shorted together or to another source of power or
ground.
Configure ONLY the first receiver in the cascade (connected to the machine inter-
face). All other receivers must be set for 2-Ch. EDM (E2), reduced resolution (RR)
off, and Trip Output (T), see " Cascaded Sensor Configuration Settings " on page
77 .
Re-configure the first receiver to adapt system to changes or replacement of other
receivers, see
" Cascaded Sensor Configuration Settings " on page 77 .
In a cascaded system, all receivers are connected together, and all emitters are connected to-
gether.
