5.1 Troubleshooting Lockout Conditions
Evaluate status indicators per Section 4.4. See Section 5.2 for
Test mode indication.
A Lockout condition causes all of the EZ-SCREEN LP’s 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
Sections 5.1.1 and 5.1.2 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:
Emitter
Status indicator Flashing Red
Diagnostic Display Error code (flashing)
Receiver
Reset indicator OFF
Status indicator Flashing Red
Zone Indicators OFF
Diagnostic Display Error code (flashing)
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.
Emitter and Receiver Reset
Close the remote reset switch for 1/4 to 2 seconds and then
open the switch (per Section 4.3), 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 Section 4.3, is
required to resume full operation.
WARNING . . .
Lockouts and Power
Failures
Power failures and Lockout conditions are indication of a problem
and must be investigated immediately by a Qualified Person.
Attempts to continue to operate machinery by bypassing the
EZ-SCREEN LP or other safeguards is dangerous and could
result in serious bodily injury or death.
WARNING . . .
Shut Down Machinery
Before Servicing
The machinery to which the EZ-SCREEN LP 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, or the appropriate standard for
controlling hazardous energy). Servicing the EZ-SCREEN LP
while the hazardous machinery is operational could result in
serious bodily injury or death.
