Preset Function
This function adjusts the current value to " ".
With light received, press the [PRESET] button. The current value is set to " ".
Pressing the [PRESET] button changes the setting and current value as shown below.
• Presetting with preset disabled:
The setting is changed to "
". The setting can be changed via the normal calibration
method.
• Presetting with preset enabled:
Only the current value is changed to "
", and the setting is not changed.

Work-Preset Function
This function adjusts the current value to " ".
After executing the Preset function in a condition in which you would like " " to be dis-
played, executing this function in a condition in which you would like " " to be displayed, will
adjust any two points to " " and "".
Pressing the [PRESET] button and the button at the same time will set the current
value at that time to " ". Values that have been set to "" with the Preset function cannot
be changed.
z
Maximum Sensitivity Preset Function
This function sets conditions that will serve as reference, to " " and adjusts conditions with
slightly high light intensity as " ". This is useful when you would like to perform detection
using the background as a reference with reflective models.
In the following conditions, press and hold the [PRESET] button for 3 seconds or more then
release your finger when "
#WVQ" is flashed.
• The maximum value for the light intensity while the [PRESET] button is being pressed is
set to "
, and light-intensity that is slightly higher than the maximum value at that time
will be adjusted to " ".
• The setting value is " "
• The green [PST] indicator will light up.
z
Full Auto Preset Function
This function automatically differentiates between two conditions (presence/absence of
workpiece) and adjusts the current values to "
" and "". This is effective for cases when
the workpiece is moving at high-speed.
Press and hold the [PRESET] button with no workpiece in place. While "
#WVQ" is flashing,
pass a workpiece through. (Continue pressing the [PRESET] button while the workpiece
passes through.)
• Near-maximum values while the [PRESET] button is being pressed and held are
adjusted to "
" and near-minimum values are adjusted to "" .
• The setting value is changed to " "
• The green [PST] indicator will light up.

The Zero Shift Function
This function is primarily used with reflective models.
Press the [PRESET] button and
button at the same time.
• The current value is set to "".
• Green "PST" lights up

Disable the Zero Shift Function
Press and hold the [PRESET] button to disable the zero shift function.

(when saturated).

Use the Saturation Recovery Function
Press the [SET] button while pressing the [MODE] button.
After adjusting the light transmission level and light intensity sensitivity, the current values
will be adjusted to within the ranges listed in the table that follows.

Disable Saturation Recovery
When the saturation recovery function is enabled, press the [SET] button while pressing the
[MODE] button to cancel it.
Handy Uses for the Preset Function
This function is most useful when performing simple detection using a thru-
beam model fiber unit (e.g. completely blocked detection, such as when all
light axes of the fiber unit are interrupted by opaque workpieces).
The Work-Preset function can be used while the Preset function is in use
(when Preset is enabled).
When using this function with reflective models, " " will be displayed when
there is a workpiece, and " " will be displayed when there is no workpiece,
making it easy to know when the workpiece is present or absent. Additionally,
even when with a reflective model, the background has higher light intensity
than the workpiece, if you set a condition with low light intensity to "
" using
the Preset function and then using the Work-Preset function, register a condi-
tion with high light intensity as "
", the background will display as "" and when
the workpiece is present, it will be displayed as " ".
Cannot be executed when the Preset function is already being used (when
the [PST] indicator is flashing). Press and hold the [PRESET] button to dis-
able the Preset function before executing this function.

Cannot be executed when the Preset function is already being used (when

able the Preset function before executing this function.
The zero shift and preset function cannot be used together. To use the
preset function, you must first disable the zero shift function.
Handy Uses for the Zero Shift Function
This function is primarily used to set the current value to "0" on a reflective
model fiber unit.
When a reflective model is first installed, the light intensity is sometimes not
set to "0".
If this happens, using the zero shift function to set the value to "0" when there is
no workpiece allows for easier understanding of the difference in light intensity.

Handy Uses for the Saturation Recovery Function
This function is useful when the intensity value is saturated after installation.
This function corrects the saturation via a simple operation, by automatically
calibrating the light transmission level and light intensity gain.
