Set the mode selection switch to ‘SET’.
Press ‘ON’ button.
(The stability indicator will blink twice.)
[Response time: 0.5ms or less (Note)]
Set the mode selection switch to ‘RUN’.
(This completes the setting for one sensor.)
Apply steps 1 and 2 for the second sensor.
Press ‘OFF’ button.
(The stability indicator will blink twice.)
[Response time: 0.7ms or less (Note)]
Set the mode selection switch to ‘RUN’
(This completes the setting.)

A mark can be put on the nameplate on the side of the sensor

Off-delay timer function
(For standard and remote sensitivity setting types only)
Standard and remote sensitivity setting types have an approx. 40ms
fixed off-delay timer. The timer works when the timer operation
selection switch is set to ‘OFD’. The output is extended for a certain
period of time, and is useful when the response time of the connect-
ing device is slow or when the sensing signal from a tiny object is
too short.

Use of remote sensitivity setting input
(For FX-77, FX-77G only)
Basically, the method is similar to that described in ‘Use of sensitivity
setting buttons’. However, instead of pressing the sensitivity setting
buttons, make the remote sensitivity setting inputs Low.
Answer back function
The self-diagnosis output turns ON for approx. 40ms when ON input or OFF
input is accepted by the sensor. (This output does not turn ON if there is no
sensitivity difference between ON input and OFF input and stable sensing is
not achieved.)

Time chart
Sensitivity margin indicating function (Incorporated in all models)
After setting the sensitivity, the margin of the sensitivity can be
visually confirmed. The sensitivity margin can be confirmed by the
number of times the stability indicator (green) blinks when the
mode selection switch is changed from ‘SET’ to ‘SIF’ or ‘RUN’.
Normally, the margin should be set as large as possible. (Method of
increasing the margin: shorten the sensing distance, use the
optimum fiber cable, etc.)
Interference prevention function (Incorporated in all models)
The FX-7 series has a built-in interference prevention function. Two fiber cables
can be mounted very closely by setting different emission frequencies.

During period T3, do not change the incident light intensity by

Signal condition
Input impedance: 10kΩ
Sensitivity registered by remote sensitivity setting inputs has a priority over
the manual setting and it cannot be cancelled manually. To cancel the
remote sensitivity setting, arrange one switch at the position
shown in the figure, and
make it open. (The
sensitivity will be locked.)
Turn on the switch for
making sensitivity settings
effective.
Note: When using the interference prevention function, the hysteresis and
the response time increase as compared to that during normal ope-
ration. Always check the operation after setting the interference pre-
vention function.
