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.
For FX-305(P)
The FX-305(P) is equipped with two independent outputs, but
the items that can be set in output 1 and output 2 respectively
are only the following.
The items other than those are common.
1
Threshold value
2
Output operation
3
Timer operation and Timer period
4
Sensing mode
Teaching
•
The threshold values can be set by 2-point teaching, limit
teaching, full-auto teaching or window comparator mode
(1-point, 2-point, 3-point teaching) [only for FX-305(P)],
when the MODE indicator / TEACH (yellow) lights up.
•
This is the method of setting the threshold value by teaching
two levels, corresponding to the object present and object
absent conditions. Normally, setting is done by this method.
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 present condition.
If the teaching is accepted, the read incident
light intensity blinks in the digital display.

If the teaching is accepted, the read incident
light intensity blinks in the digital display
and the threshold value is set at the mid-
value between the incident light intensities
in the object present and the object absent
conditions. After this, the judgment on the
stability of sensing is displayed.
• In case stable sensing is possible: “ ” is displayed.
• In case stable sensing is not possible: “ ” blinks.
The threshold value is displayed.

(only FX-301B/G/H)
The incident light intensity appears in the
digital display and the setting is complete.
Notes: 1) Do not move or bend the ber cable after the sensitivity setting.
Detection may become unstable.
2) In case a reective-type ber is used, maximum sensitivity will be
set if the jog switch is pushed while in no work status in procedure
and .
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 the jog switch
continuously for 0.5 sec. or more with the object
moving on the assembly line. (The incident light
intensity is displayed during sampling.)
“ ” is displayed on the digital display. Release
the jog switch when the object has passed.
If the teaching is accepted, the read incident
light intensity blinks in the digital display
and the threshold value is set at the mid-
value between the incident light intensities
in the object present and the object absent
conditions. After this, the judgment on the
stability of sensing is displayed.
• In case stable sensing is possible: “ ” is displayed.
• In case stable sensing is not possible: “ ” blinks.
The threshold value is displayed.
“ ” blinks in the digital display.
(only FX-301B/G/H)
The incident light intensity appears in the
digital display and the setting is complete.
Notes: 1) The threshold value’s shift amount can be selected in PRO mode.
Refer to the “PRO Mode Operation Guide” for more details
pertaining to setting instructions. (Increments of 5 % between –45
and 45 % for setting possible. 0 % default.)
2) Do not move or bend the ber cable after the sensitivity setting.
Detection may become unstable.
In case of 2-point teaching
•
Full auto-teaching is used when it is desired to set the
threshold value without stopping the assembly line, with
the object in the moving condition.
In case of full auto-teaching
