PRECAUTIONS FOR PROPER USE

• 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

Set the fiber within the

sensing range.

Press MODE key to light

For

FX-305(P), select either Output 1 “

in the object absent condition. If the teaching

is accepted, the read incident light intensity

Turn jog switch to the “+” side or “–” side.

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 reflective type fibers.

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 fibers.

After this, the judgment on whether the setting

shift amount can be shifted or not is displayed.

•

In case shifting is possible: “

•

In case shifting is not possible: “

(only

FX-301B/G/H)

The incident light intensity appears in the

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 fiber cable after the sensitivity setting.

Detection may become unstable.

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 specifications of the connected device require a

signal of a fixed 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.

the separately prepared “PRO Mode Operation Guide”.

Please download the instruction manual from our website for

setting of threshold value when used in combination with liquid

level sensing fiber

FD-F8Y and with pipe-mountable liquid level

sensing fiber

FD-F4□.

Refer to p.1458~ for general precautions and to the “PRO mode operation guide”

on our website for details pertaining to operating instructions for the amplifier.
