PRECAUTIONS FOR PROPER USE
Refer to General precautions, p.80~ for ber precautions, and to the “PRO mode operation
guide” on our website for details pertaining to operating instructions for the amplier.
•
This is the method of setting the threshold value by
teaching only the object absent condition (stable incident
light condition). This is used for detection in the presence
of a background body or for detection of small objects.
Step
Description Display
Set the ber within the
sensing range.
Press MODE key to light
up MODE indicator /
TEACH (yellow).
For FX-305(P), select either Output 1 “ ” or
Output 2 “ ” beforehand, press jog switch
in the object absent condition. If the teaching
is accepted, the read incident light intensity

If jog switch is turned to the “+” side, “ ” scrolls
(twice) the display from right to left (Note 1), and the
threshold level is shifted to a value
approx. 15 % higher (lower sensitivity)
than that set at . (Note 2)
This is used in case of reective type bers.
If jog switch is turned to the “–” side, “ ” scrolls
(twice) the display from left to right, and the threshold
level is shifted to a value approx.
15 % lower (higher sensitivity)
than that set at . (Note 2)
This is used in case of thru-beam type bers.
After this, the judgment on whether the setting
shift amount can be shifted or not is displayed.
• In case shifting is possible: “ ” blinks.
• In case shifting is not possible: “ ” blinks.
The threshold value is displayed.

digital display and the setting is complete.

Notes: 1) Scrolling display is not available in FX-301B/G/H.
2) The approx. 15 % amount of shift is the initial value. The amount of
shift can be changed in the PRO mode from approx. 5 to 80 %
(5 % step). Refer to the “PRO Mode Operation Guide” for more
details pertaining to setting instructions.
3) Do not move or bend the ber cable after the sensitivity setting.
Detection may become unstable.

For FX-305(P), select either Output 1 “ ”
or Output 2 “ ” beforehand, in case the
threshold value is to be increased (sensitivity
to be reduced), turn the jog switch
to the “+” side to increase the
threshold value slowly. If the
jog switch is turned continuously to the “+”
side, the threshold value increases rapidly.
In case the threshold value is to be decreased
(sensitivity to be increased), turn the jog
switch to the “–” side to decrease the
threshold value slowly. If the jog
switch is turned continuously to
the “–” side, the threshold value
decreases rapidly.

Timer operation setting
•
The setting for whether the timer is used or not can be
done when MODE indicator / TIMER (yellow) lights up.
For FX-301B/G/H, the timer type can be set in PRO
mode.
•
Further, an OFF-delay (initial value) which is useful when
the response of the connected device is slow, etc., an
ON-delay which is useful to detect only objects taking a
long time to travel, and ONE SHOT, which is useful when
the input specications of the connected device require a
signal of a xed width, are possible with the FX-301□(-HS).
FX-305(P) is also equipped with ON-delay • OFF-delay and
ON-delay • ONE SHOT timers. Refer to the “PRO Mode
Operation Guide” for the setting method of the OFF-delay,
ON-delay and ONE SHOT timer intervals.
