2) When using test input function
This device incorporates the test input function. Using this function, it is possible to simulate the light blocked
status.
<Reference>
When the test input / reset input is kept open (for manual reset of PNP output: connect to +V, for manual reset of NPN
output: connect to 0V), the test input function will be valid and the receiver will be OFF with the emitting light is received.

Notes: 1) In case of SF4C-F□, the position of digital indicator (red) is different as right figure.
Also, digital indicator (red) is not incorporated in SF4C-F15□.
2) Vs is the applying supply voltage.
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.
4) 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.
