Troubleshooting and Lockout Conditions
Evaluate status indicators per Status Indicators on page 44.
A Lockout condition causes all of the EZ-SCREEN Type 2 OSSD outputs to turn or remain OFF, sending a stop signal to the guarded
machine. Each sensor provides diagnostic information, via the LEDs, to assist in the identification of the cause(s) of lockouts. Lockout
conditions are indicated as shown in
Table 1: Troubleshooting on page 48.
Recovery Procedures
To recover from a Lockout condition, correct all errors and perform sensor resets as indicated below.
Receiver (System Reset)
Open the Reset switch for 1/4 second and then close it, or (for Trip Output models not using a reset button) power the sensor down, wait
a second or two, then power it up.
Emitter Reset
Power the sensor down, wait a second or two, and then power it up (in the unlikely event that an emitter reset is needed).
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 Type 2
System or other safeguards is dangerous and could result in an increased risk of harm.
WARNING: Shut Down Machinery Before Servicing
The machinery to which the EZ-SCREEN Type 2 System 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 Type 2 while the hazardous machinery is operational could result in serious bodily injury
or death.
