Changing the warning output level
A warning is output
when the amplifier
detects variation of the
received light intensity
in the range where the
output does not turn
on.
When the received light
intensity stays between
the warning level and
set value, the received
light intensity calibra-
tion stops, the DTM
indicator flashes, and a
warning is output.
A level for outputting a
warning can be set in
the range of 0P (0%) to
100P (100%).
(Default: 50P (50%)).
• 100P (100%) : A warning is not output even if the received light intensity
changes.
• 50P (50%) : A warning is output if the received light intensity drops to the mid-
dle between the received light intensity when no workpiece is
present and the setting value.
• 0P (0%) : A warning is output if the received light intensity drops even
slightly.
The output type (LV-N11 / N12 ) can output the warning state to an exter-
nal device with the 2-output setting ( ).
For details, see "Warning output mode" (page 4-35).
Refer to page 4-2 "Detection Settings (Func)" for setting methods.

A warning is output if the received light
intensity, when no workpiece exists, does
not increase to the warning level because of
beam axis deviation, etc.
