2-point teaching
The basic teaching method when the sensing object is present is

1. Press the SET key when the sensing object
is present
(system command / Index2: 0x43).
2. Press the SET key when the sensing object
is absent
(system command / Index2: 0x44).
Display when stable sensing is possible.
Display when stable sensing is not possible.
Limit teaching
When the sensing object is small or there are objects in the background,
use this teaching method.
Sensing object is present
Sensing object is not present
1. Press the SET key
when the sensing
object is present or
not present.
2. Use the instructions according to your sensor type:
•
Thru-beam type, specular reflective type: Press the UP key to shift the
threshold level to a high level (low sensitivity) or press the DOWN key
to shift the threshold level to a low level (high sensitivity) (Notes 1, 2).
•
Thru-beam type, specular reflective type: Press the UP key to shift the
threshold level to a high level (low sensitivity) or press the DOWN key
to shift the threshold level to a low level (high sensitivity) (Notes 1, 2).
•
Reflective type: Press the DOWN key to shift the threshold level to a
high level (low sensitivity) or press the UP key to shift the threshold
level to a low level (high sensitivity) (Notes 1, 2).
Display when stable sens-
ing is possible.
Display when stable sens-
ing is not possible.
Notes:
1. The shift value of approx. 15% is an initial value. Display of the shift value can be
changed to percentage [approx. 0 to 999% (unit 1 %)] or incident light intensity [0
to 9999 (unit 1)].
For setting the shift amount, refer to <PRO1> in section 12 “
PRO MODE
”.
2. At the time of limit teaching. UP key
(System command / Index2: 0x4B)
DOWN key (System command / Index2: 0x4C)
Auto teaching
When the sensing object is moving, use this
teaching method.
1. Press and hold the SET key for a long time
2. Run the sensing object on the production
line and hold down the SET key (system
command / Index2: 0x47)
.
3. The display shows
in green. When
the sensing object has passed through,
release the SET key (system command /
Index2: 0x48).
Display when stable sensing is possible.
Display when stable sensing is not possible.

Threshold value fine adjustment function
● The fine adjustment of the threshold value can be set in RUN mode
and during IO-Link communication.

2.
1. Press the UP key to in-
crease the threshold value
2. Press the DOWN key to
decrease the threshold value

3. Press the SET key to save
the threshold value.
4. The value has been saved.
If you do not press the
SET key, the value will be
saved automatically after 2
seconds.

Key lock function
The key lock function protects settings from being changed inadvertently.
The function can also be activated via IO-Link communication. When the
key lock function is activated and you press any of the keys, the digital
display shows
.
Activating the key lock function
1. Press the SET and the MODE key together for
3 seconds or longer.
The digital display changes to show the key
lock function has been activated.
Then the digital display returns to show the
current values.
Deactivating the key lock function
1. Press the SET and the MODE key together for
3 seconds or longer.
The digital display changes to show the key
lock function is active.
The digital display changes to show the key
lock function has been turned off.
Then the digital display returns to show the
current values.
