6.2.2 Receiver Error Codes
Diagnostic
Display 10
Error Description
Cause of Error and Appropriate Action
Output Error
Error is caused by:
•
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)
•
Disconnect the OSSD loads and reset 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.
Reset Input Error
This error occurs when the Reset switch is closed
(or the wiring is shorted to +24 V) during power-
up.
•
Verify that the reset switch is in the open position.
•
Reset the receiver per EZ-SCREEN Checkout Procedures: Shift and
Daily Checkout Procedure.
•
If the error remains, disconnect the reset wire at pin 8; cycle
power.
•
If the error clears, the problem is in the reset switch or in the
wiring.
•
If the error continues when the reset wire is disconnected, replace
the receiver.
EDM Input Error
Can occur for the following reasons:
•
EDM wiring configuration does not match
the EDM switch configuration
•
No connection to EDM connections
•
Both EDM inputs fail to respond within
250 ms of each other
•
Excessive noise on EDM inputs
•
Loose QD connection(s)
•
Verify that the EDM configuration switches are set correctly and
that the wiring is correct for the EDM type configured (see
Machine Primary Control Elements
on page 33).
•
Reset the receiver.
•
If the error continues, remove power to the guarded machine,
disconnect the OSSD loads, disconnect the EDM input signals,
configure EDM for No Monitoring (
on page 33) and conduct the Initial Checkout procedure
in
on page 27.
•
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
on page 33.
•
If the error continues, check for noise on the EDM inputs (see
on page 41). If error continues,
replace the receiver
Receiver Error
This error can occur due to either excessive
electrical noise or an internal failure.
•
Perform a reset per EZ-SCREEN Checkout Procedures: Shift and
Daily Checkout Procedure.
•
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
on page 27).
•
If the error clears, check the external connections and
configuration settings.
•
If the error continues, 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.
EDM1 Error
This error can occur due to EDM 1 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
on page 33.
•
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
on page 33) 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
on page 33.
•
If the error continues, check for noise on the EDM inputs (see
on page 41).
10 Multiple-digit codes are sequential, followed by a pause.
