Test input polarity selection switch
Notes: 1) Connect the light curtain’s shield wire to the frame ground (F.G.), and ground the SF-AC’s PE terminal.
Notes:
2) If using the equipment with the manual reset, wire X1 to X2 as per the illustration above.
If using with the automatic reset, disconnect X2 wire and connect it to X3. In this case, reset button is not required.
Notes:
3) Use a momentary-type switch for the reset button.
Set the test input polarity
selection switch of SF-AC
to the ‘PNP’ side.
