■ When using the LV-S31
Toggling the Display
■ When using a model other than LV-S31
• When "duAl" is selected for the number of digits of light intensity dis-
play and "Std" is selected for display mode
* The displayed number indicates the following type of alarm.
For more information about remedies to errors, see "Error indication" on page 10.
1: Over DSC correction limit
2: DSC small fluctuation detection
3: Invalid DSC EEPROM contents
4: Over fluctuation width during zero datum calibration
5: DSC speed limit alarm
• When "duAl" is selected for the number of digits of light intensity dis-
play and "FuLL" is selected for display mode
*1 The received light intensity is displayed in percentage with reference to
the setting value.
*2 Its stability is indicated between 85 to 115 %. The number is varied by
the unit of 5 %.
*3 The peak- and bottom-hold values since the power-on are displayed.
The hold values can be reset by pressing the manual button.

Digital display (The position of the target from the center position
[5000] is displayed in number.)
Outside of the detection range
The workpiece is near the sensor with reference
to the digital display range.
With 5000 being the middle, the value
increases as the distance from the sensor increases.
The workpiece is far from the sensor with reference to
the digital display range.
Outside of the detection range
Position display (The position of the target with reference to the
center position is displayed.)
Outside of the detection range
Outside of the detection range
The number of bars increases as the distance from
the sensor increases, taking the state of "A" as the
center.
When adjusting the center position with the trimmer
on the sensor head, adjust it to the state of "A".
