Evaluate status indicators per " Status Indicators " on page 56 .
A Lockout condition causes all of the EZ-SCREEN SLS 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 " on page 86 and " Emitter Error Codes " on page 88 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:
Receiver Emitter
Reset indicator OFF Status indicator Flashing Red
Status indicator Flashing Red Diagnostic Display Error code (flashing)
Zone indicators OFF
Diagnostic display Error code (flashing)
To recover from a Lockout condition, correct all errors and perform a single sensor reset sequence as described below.
Receiver Reset — Close the remote reset switch for 0.25 to 2 seconds and then open the switch (per " Reset Procedures " on
page 55 ), 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 "Reset
Procedures " on page 55 , is required to resume full operation.
Emitter Reset — Power the sensor down, wait a second or two, and then power it up.
WARNING:
Lockouts and power failures indicate a problem
Attempts to continue to operate machinery by bypassing the Banner Engineering Corp. device or
other safeguards is dangerous and could result in serious injury or death.
A Qualified Person
