3) When an error occurs
If a sensor error is detected, the sensor will turn the control output (OSSD 1, OSSD 2) off and
the digital error indicator (red) on the receiver lights up and the fault indicator (yellow) on the
emitter and receiver light 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 go into OFF state. Also, the emission halt indicator (orange) of the
emitter blinks.
<Emitter> <Receiver>
Notes: 1) Since the color of the operation indicator changes according to the ON / OFF state of the control
output (OSSD 1, OSSD 2), the operation indicator is marked as ‘OSSD’ on the sensor.
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, OSSD 2) short-circuit, extraneous light de-
tection, sensor failure, etc.
Refer to ‘
Chapter 5 Troubleshooting
’ and remove the source of error.
