EZ-SCREEN Point
Instruction Manual
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
Status indicator Flashing red
Diagnostic display Error code
Receiver
Reset indicator OFF
Status indicator Flashing red
Beam Status indicator OFF
Diagnostic display Error code
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.
