EZ-SCREEN
LS Basic Safety Light Screen
9 Troubleshooting
9.1 Lockout Conditions
A Lockout condition causes all of the EZ-SCREEN LS Basic OSSD outputs to turn or remain Off, sending a stop signal to
the guarded machine. Each sensor provides diagnostic error codes to assist in the identification of the cause(s) of lockouts
(see
Receiver Error Codes and Emitter Error Codes ) ).
The following tables indicate a sensor lockout condition:

Diagnostic display
If both the emitter and its corresponding receiver do not have the same scan code setting, the receiver indicates that Beam
1 is blocked (the Diagnostic display indicating "C" "H" "1" as shown in
lockout and can occur if the Scan Code input is not wired the same for both sensors or if the EDM circuit has not been re-
wired for one-channel monitoring in retrofit installations of two-channel EDM applications (see the warning in
Device Monitoring Hookup
9.2 Recovery Procedures
To recover from a Lockout condition, correct all errors, power the sensor down, wait a few seconds, and then power the
sensor back up.
WARNING: Lockouts and Power Failures
Power failures and Lockout conditions are indication of a problem and must be investigated immediately
by a Qualified Person
other safeguards is dangerous and could result in serious injury or death.
WARNING: Shut Down Machinery Before Servicing
The machinery to which the Banner device is connected must not be operating at any time during major
service or maintenance. This may require lockout/tagout procedures (refer to OSHA1910.147, ANSI
Z244-1, ISO 14118 or the appropriate standard for controlling hazardous energy). Servicing the Banner
device while the hazardous machinery is operational could result in serious injury or death.

If the error clears, the problem is in the OSSD load(s) or in the
load wiring.
