3) When an error occurs
If a device error is detected, the device will turn the control output (OSSD 1 / 2) OFF. Then the
digital error indicator (red) on the receiver lights up and the fault indicators (yellow) on the emit-
ter and receiver light up or blink.
● If an emitter error is detected, the emitter will be locked out, stopping its emission, and the
control output (OSSD 1 / 2) will be turned OFF.
● If a receiver error is detected, the receiver will be locked out, and the control output (OSSD 1
/ 2) will go into OFF state. Also, the emission halt indicator (orange) of the emitter lights up.
Notes: 1) Since the color of the operation indicator changes according to the ON / OFF state of the control
output (OSSD 1 / 2), the operation indicator is marked as "OSSD" on the device.
2) Refer to "Chapter 5 Troubleshooting" for details of the digital error indicator.
3) The status of the emitter / receiver indicators during operation above shows the case in PNP output
setting mode. In case of NPN output setting mode, the NPN indicator (orange) lights up.
Since this device will not return to normal operation automatically after the removal of the
source of error, it is necessary to turn the power OFF and ON again.
(Source of error): The control output (OSSD 1 / 2) short-circuit, extraneous light detection,
Refer to "Chapter 5 Troubleshooting" and remove the source of error.
