3. Tuning modes
Tuning mode can be selected from manual tuning, in which settings
are changed directly by button operation an 3 types of auto-tuning.
Target detection continues to function during manual tuning, but
control output turns OFF during auto-tuning.
3.1 Manual tuning
3.2 Auto tuning
Auto-tuning can be selected from 3 types: 2-point tuning, BGS
tuning (max. sensitivity setting) and percent tuning. During auto-
tuning, the optimal sensitivity level for the incoming light is
automatically set by the automatic sensitivity switching. However, if
a fixed sensitivity is desired for auto-tuning, the automatic sensitivity
switching can be disabled by the option setting.
After detection with the work piece present and absent, the middle
point between the 2 is used as the set value.
When the difference in received light level between the 2 points is
small or when absolute light level is low, a setting error may occur.
In this case, check the sensor installation conditions and then carry
out the auto tuning again.
For a diffuse-scan fiber unit with no work piece present, the
maximum value at which the background is not detected is used as
the set value.
If BGS tuning is executed for a diffuse scan fiber unit without a
background or target object present, or a thru-scan fiber unit with a
target object present, the value can be set at the low limit (max.
sensitivity setting).
Uses a specified percentage of the incoming light level as the set
value. If setting at the specified percentage is not possible, a setting
error will occur. In this case change the sensor’s installation
conditions or the specified percentage and the carry out the auto
tuning again.
4. Functions
4.1 Sensing types
Sensing types are a combination of a response time and a
sensitivity level. There are 3 response times (Ft/SF/nL) and 4
incoming light sensitivity levels (4/3/2/1 in descending order of
sensitivity), therefore there are 12 sensing types. If configuration is
not possible due to incoming light saturation caused by close-range
detection, etc., use a lower sensitivity sensing type (**3/**2/**1) and
then do an operational check.
4.2 Timer type
Two output timer functions are available: on-delay and off-delay.
The time range for each timer is from 1 ms to 5 s.
Response times shown are for emitter frequency Fr-1.

3.3 Remote teach-in
Auto tuning can be executed by an external input signal (wire ext.
teach). If the remote tuning function is not needed, connect the wire
to 0V:
