If (MODE key) is pressed for 2 sec. while setting is in progress in a mode other than RUN mode, the mode
will switch to RUN mode. When this occurs, the settings which had been changed before (MODE key) was

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.)

5-2. Teaching

This is the method of setting the threshold value by teaching two levels, corresponding to
object present and object absent conditions. Normally, setting is done by this method.
