Outputting Alarms

Limit Setting Function (Page 7, No. 9)

Limit settings output a warning when the difference in light intensity becomes too
small for detecting whether a workpiece is present.
• It can be used when "Limit Setting Function" is selected on page 7, No. 9.

There are two types of limit setting functions.

Peak value

This function samples the peak value when the light intensity rises above the set
value for detection output. The warning outputs when the minimum hold value
drops below the setting value for alarm output.

Bottom value

This function samples the bottom value when the light intensity falls below the set
value for detection output. The warning outputs when the maximum hold value
rises above the setting value for alarm output.

Resetting peak value and bottom value

Press and hold the

button and the

button for at least 3 seconds to

reset the values.

The function is reset when the power is turned off.
