Limit setting output mode
Setting output 2 to " LiMt " (limit setting output mode) enables detection of reductions in
received light intensity for output 1. Specifically, if the cumulative minimum of peak
value for output 1 falls below the limit setting value, it is recognized as a reduction in
received light intensity and therefore output 2 is turned on.
"Light intensity hold display" (page 4-25)
 Timing chart
For period (1), the peak value
is not below the limit setting
value, so output 2 remains
OFF.
For period (2), the peak value
is below the limit setting value,
so output 2 turns ON.
For period (3), the peak value
again is above the limit setting
value, so output 2 turns OFF if
Auto (Auto) is selected. If USEr
(User) is selected, the
cumulative minimum of peak
values is the peak value
during period (2), which is below the limit setting value, so output 2 remains ON.
 How to reset after the output is activated
Refer to page 4-3 "2-output Settings ( )" for setting methods.
