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.

4.1 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.
