9.1 Troubleshooting and Lockout Conditions
Evaluate status indicators per
A Lockout condition causes all of the EZ-SCREEN 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
on page 80 or the Diagnostic Error Code label supplied in the
documentation pack).
The System provides easy methods for determining operating problems. A Lockout condition is indicated by the following:

9.2 Recovery Procedures
To recover from a Lockout condition, all errors must be corrected and a single sensor reset sequence must be performed as
described below.
9.2.1 Emitter and Receiver Reset
Receiver Reset
Close the remote reset switch for 0.25 to 2 seconds and then open the switch (per
on page 50), or power
the sensor down, wait a second or two, then power it up.
Note: If the receiver is set for latch output, a manual reset using a remote switch, as described in
on page 50, is required to resume full operation.
Emitter Reset
Power the sensor down, wait a second or two, and then power it up.

must immediately investigate the problem.
WARNING:
• Shut down the machinery before servicing
• Servicing the Banner device or system while the hazardous machinery is operational could result
in serious injury or death.
• The machinery to which the Banner device or system is connected must not be operating at any
time during major service or maintenance. This might require lockout/tagout procedures (refer to
OSHA1910.147, ANSI Z244-1, ISO 14118 or the applicable standard for controlling hazardous
