SET Mode
5-1. SET Mode Functions and Settings
5
SET mode is the mode used for making basic settings. Settings for five functions can be configured.
: Teaching The ‘threshold value’ can be set by utilizing three kinds of teaching, whichever
‘2-level teaching’, ‘limit teaching [,]’ or ‘full-auto teaching’.
Make sure that detection may become unstable if less margin is applied in the
use environment when teaching.
Refer to p.7lfor setting procedure
: Output Operation Setting
This mode allows the selection of output operation from either L-ON (Light-ON),
or D-ON (Dark-ON).
When set to ‘L-ON’, the output will be ON if the incident light intensity becomes
greater than the ‘threshold value’.
When set to ‘D-ON’, the output will be ON if the incident light intensity becomes
less than the ‘threshold value’.
* The factory setting is ‘Dark-ON (D-ON)’.
Refer to p.10 for setting procedure
2-level teaching is a method of setting the threshold value by teaching the amplifier unit
two different status conditions - sensing object present and sensing object absent.
The ‘threshold value’ is normally set using this method.
P. 7
P. 8 l
2-level Teaching
Limit Teaching [, ]
Teaches only the status condition in which no sensing object is within sensing range
(status in which incident light intensity is stable). This method is used to set a ‘threshold
value’ for conducting sensing in the presence of a background, or when extremely
small objects are to be detected.
P. 9
Full-auto Teaching
This method is used to set the threshold value while the sensing objects are still
moving on the production line, without stopping the production line.

If the incident light intensity is still saturated (4,000 or higher) even when the
light reduction setting is used, make the distance between the sensing
objects and the fiber head longer.
• For the FX-101:, the interference prevention function will not operate for
emission frequency 0 (factory setting).
• The response time will change when the emission frequency is changed.
: Timer Operation Setting
This sets timer operation and timer period.
Without timer, ON-delay timer, or OFF-delay timer can be set.
In case of setting ON-delay timer or OFF-delay timer in the timer operation
setting mode, timer period can be set.
Select timer period from 1 ms, 5 ms, 10 ms, 20 ms, 40 ms, 50 ms, 100 ms, 500
ms, and 1,000 ms.
* The factory setting is ‘Without timer’.
Refer to p.10 for setting procedure
: Light-emitting Amount Selection Setting
Allows light reduction to be set for the light-emitting amount.
When the setting is ON, the light-emitting amount is reduced.
Use this setting if sensing is difficult because the incident light intensity is
saturated (4,000 or higher).
* The factory setting is ‘OFF’.
* The factory setting is emission frequency 0 for the FX-101:and emission frequency
1 for the FX-102:.
Refer to p.11 for setting procedure
: Emission Frequency Setting
When fiber heads are used side-by-side, the emission frequencies for each
amplifier can be set to different frequencies in order to prevent interference.
For the FX-101:, this function is activated by setting the emission frequency to
1, 2 or 3.
For the FX-102:, this function is activated by setting the emission frequency to
1, 2, 3 or 4.
<Number of units for interference prevention>
• Combination of FX-101:only: Maximum 3 units
• Combination of FX-102:only: Maximum 4 units
• Combination of FX-101:and FX-102:: Maximum 4 units
The beam-emitting part and the operation indicator (orange) will blink while the
emission frequency is being set. (They light up steadily when emission frequency 0 is
set.) The blinking cycle will change depending on the emission frequency which is
selected. (Refer to the table below.)

: Threshold Value Follow-up
Cycle Setting
Follow-up of the threshold value can be carried out within a set range (shift amount)
in response to fluctuations in the incident light intensity. The threshold value
follow-up operation functions by setting the time for refreshing of the threshold value.
At this time, the threshold value at the time of the refresh is indicated on the green
digital display.
However, the threshold value is not stored. (The threshold value returns to the
original value when the power is turned off.)
The threshold value follow-up cycle can be set to between 1 to 59 sec. (1-sec.
intervals), 1 to 9 min. (1-min. intervals) and 10 to 60 min. (10-min. intervals).
The incident light intensity is checked and the threshold value is reset each time
after the threshold value follow-up cycle which has been set.
However, the threshold value is not stored.
The shift amount for follow-up is the shift amount which has been set according
to ‘6-2. Shift setting’ (p.18).
Shift amount: Can be set to between 0 to 80 % (1 % intervals).
(The factory setting is ‘15 %’. )
Refer to p.19 for setting procedure
When threshold value follow-up operation is being carried out, the follow-up
operation stops when the incident light intensity drops to 300 or lower.
At this time, the threshold value blinks in the digital display (green).
[Usage conditions]
This is enabled when thru-beam type fibers or retroreflective type fibers are
being used and output operation is set to Dark-ON.
*If output operation is set to Light-ON, the threshold value is not refreshed.

: GETA Function Setting
The display value for the incident light intensity can be offset by the desired
value (target value).
The target value can be set to between 0 and 2,000 (in intervals of 100).
For example, if the incident light intensity is 1,500 and the target value is set to
2,000, then the value appearing in the digital display will be 2,000.
Refer to p.20 for setting procedure

• If you press (MODE key) during RUN mode when using the GETA
function, the incident light intensity before the GETA function was used will
be indicated on the red digital display for 2 sec.
• If this function is used while the incident light intensity is saturated (4,000 or
higher), ‘ ’ will be indicated on the red digital display. The maximum
offset value is 4,000.
Because the original
value is 500, the
displays for the lower
limit value will be 500
and the upper limit
value will be 4,000.
Because the original

: Digital Display Inversion Setting
The viewing orientation of the digital display can be inverted in accordance with
the mounting direction of the amplifier.
*The factory setting is ‘Turn OFF’.
• Be sure to use the setting copy function between the identical models (for all
FX-101:units or all FX-102:units). This function cannot be used between
different models.
• Only one amplifier can be connected on slave side with a master side
amplifier for the setting copy function. If copying to more than one unit,
make the settings for one unit at a time.
• ‘Threshold value’, ‘output operation setting’, ‘timer operation setting’, ‘timer
period setting’, ‘light-emitting amount selection setting’, ‘shift setting’, ‘ECO
setting’, ‘digital display inversion setting’, and ‘threshold value margin
setting’ can be copied.
Refer to p.22 for setting procedure
: ECO Setting The digital display can be set to turn off in order to reduce power consumption
(current consumption). When the ECO setting has been set to ON, ‘ ’ will
blink if no keys have been pressed for approx. 20 sec. while in RUN mode, and
then the digital display will switch off.
To switch the digital display back on again, press and hold any one of the three
keys for 2 sec. or more.
*The factory setting is ‘ECO OFF’.
Refer to p.21 for setting procedure
Note that key operations will be invalid if the ECO setting has been set by means of external input.

: Threshold Value Margin Setting
Margin for threshold value to the present incident light intensity can be checked.
When there is no margin, it is possible to make the digital display blink. The
incident light intensity when the display starts blinking will be approximately half
of the shift amount. [For the shift amount, refer to ‘Shift setting (p.13, p.18)’.]
The blinking method for the digital display can be selected from blinking green
(threshold value blinks), blinking red (incident light intensity blinks) and blinking
green and red simultaneously (threshold value and incident light intensity blink
simultaneously).
*The factory setting is ‘OFF’.
The incident light intensity range
that will cause the digital display
to blink will be from approx. 900 to
approx. 1,100.
Refer to p.22 for setting procedure
: Setting Copy The settings of the master side amplifier can be copied to the slave side
amplifier.
The copying method used is data communication by means of connected wiring.
For details on the setting procedure and wiring, refer to p.23.
*The factory setting is ‘Do not copy settings (Copy NO)’.
Refer to p.23 for setting procedure
