(Note 1) :
Under the following conditions, the FSDs (sensing output) are turned off.
(1)When one or more beams are interrupted [unless the sensor unit is muted (SF1-AC1 only)].
(2)When the sensor unit falls into an abnormal condition (sensor failure) [unless the sensor unit is muted. (SF1-AC1 only)].
(3)When the sensor unit receives intense ambient light [unless the sensor unit is muted (SF1-AC1 only)].
(4)When the sensor unit cable or the mating cable is broken or short-circuited [unless the sensor unit is muted (SF1-AC1 only)].
(5)When the external FSD-OFF input is short-circuited (SF1-AC1 only).
(6)When the test input terminals are open (SF1-AC2 only).
(Note 2) :
Under the following conditions, the SSD (lockout output) incorporated in SF1-AC1 is turned off.
(1)When commencing operation or when supplying power again after power disconnection.
(2)When one of the FSD relay contacts gets welded.
(3)When one of the MPCE relay contacts gets welded.
(4)When the results of the dual circuits incorporated in the control unit are different.
(5)When the external lockout input is open.
(6)When the MPCE operation (NO/NC) is different from the setting of the MPCE operation mode selection switch in the control unit.
(Note 3) :
Under the following conditions, the monitor output incorporated in SF1-AC2 is turned off.
(1)When one or more beams are interrupted.
(2)When the sensor unit falls into an abnormal condition.
(3)When the sensor unit receives an intense extraneous light.
(4)When the sensor unit cable or the mating cable is broken or short-circuited.
(5)When the test input is opened (emission stopped).
(Note 4) :
The muting input (SF1-AC1 only) cancels the sensor operation so that any beam interruption cannot make the FSD output relays open. This function is used to make the sensor temporarily inoperable for feeding a workpiece into a machine or removing it. This input must be carefully handled.
