Teaching
•
The threshold values can be set by 2-level teaching, limit teaching or full-
auto teaching, 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.
In case of 2-level teaching
•
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.
In case of limit teaching
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.
Stability indicator (green) blinks.
• In case stable sensing is not possible: ‘ ’ blinks.
Stability indicator (green) is off.

• In case shifting is possible:‘ ’blinks.
• In case shifting is not possible:‘ ’blinks.

Notes: 1) The threshold value’s shift amount can be selected in PRO mode.
Refer to the ‘SUNX fiber sensor home page’ (http://www.fiber-
sensor.com) for more details pertaining to setting instructions.
(Increments of 5 % between –45 and 45 % for setting possible. 0 %
default.)
Notes: 2) Do not move or bend the fiber cable after the sensitivity setting.
Detection may become unstable.
Notes: 1) 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 ‘Fiber Sensor Guide Book’ or ‘SUNX fiber
sensor home page’ (http://www.fiber-sensor.com) for more details
pertaining to setting instructions.
Notes: 2) Do not move or bend the fiber cable after the sensitivity setting.
Detection may become unstable.
PRECAUTIONS FOR PROPER USE

•
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.
