Instruction Manual
5. Troubleshooting and Maintenance
Evaluate status indicators per Section 4.3.
5.1 Troubleshooting Lockout Conditions
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 Figure 5-1).
The System provides easy methods for determining operating problems. A
Lockout condition is indicated by the following:
Emitter

Recovery Procedures
To recover from a Lockout condition, all errors must be corrected and sensor
resets must be performed as shown below.
NOTE: An emitter reset is only required if the emitter is in a Lockout condition.
Receiver Reset
Close the receiver Reset switch for 1/4 to 2 seconds and then open the switch (per
Section 4.2) or power the sensor down, wait a second or two, then power it up.
NOTE: If the power down/up method is used and the system is set for Latch
mode, a manual reset, as described in Section 4.4, is required to resume
full operation.
Emitter Reset:
Power the sensor down, wait a second or two, and then power it up.
