6-2. Output Logic

Select N.O. or N.C. for the output logic. For details, see

"4 Detection Mode" (page 5).

6-3. Output Mode

„

Standard [Standard]

The output is activated according to the detecting distance. For details, see

"4 Detection

Mode" (page 5).

„

Window [Window]

The output is activated according to the detecting distance. For details, see

" 4-3.

Window Mode" (page 6).

„

Stability [Stability]

This function can be used to check whether there has been a decrease in the amount of
light received due to problems such as dirt on the detected surface.

z

When the I/O selection is [Out1 + Out2]

Output is activated if the amount of light received falls below the threshold (fixed value)
during the observation period.

Example) Chart during DATUM mode

z

When the I/O selection is [Analog]

Output is generated if the amount of light received falls below the threshold (fixed
value) for 5 seconds or more.

„

Error [Error]

Output is activated when an error occurs. When the error is cleared, the output is also
automatically reset. For causes of errors, see

" Error Display" (page 11).

6-4. Timer

This function can be used to delay the timing with which the sensor output is switched.

• Off delay [Off-delay]
• On delay [On-delay]
• One shot [One shot]
