When An Error Occurs - Panasonic SF4С Series Instruction Manual

Operation

4.3 When an Error Occurs

If a sensor error is detected, the sensor will turn the control output (OSSD 1, OSSD 2) OFF.
Then the digital error indicator (red) on the receiver lights up and the fault indicator (yellow) on
the emitter and receiver lights up or blinks.
•
If an emitter error is detected, the emitter will be locked out, stopping its emission, and
the control output (OSSD 1, OSSD 2) will be turned OFF.
• If a receiver error is detected, the receiver will be locked out, and the control output
(OSSD 1, OSSD 2) will be turned OFF. Also, the test input indicator (orange) of the
emitter lights up.

NOTE
1. The figure shows the status of the emitter/receiver indicators during
operation when you are using a PNP output. When you are using an NPN
output, the NPN indicator lights up orange.
2. Since the color of the operation indicator changes according to whether the
control outputs (OSSD 1, OSSD 2) are ON or OFF, the operation indicator on
the light curtain is marked 'OSSD'.
