 Changing the warning output level
The unit goes into
alarm mode when it
detects a minor level of
variation of received
light intensity that does
not cause the output to
turn ON. If the received
light intensity continues
to remain between the
warning level and
setup level, the
received light intensity
correction function
stops, the DTM
indicator flashes, and
the unit goes into alarm
mode.
A level for outputting a
warning can be set in
the range of 0P (0%) to
100P (100%).
(Default: 50P (50%)).
• 100P (100%) : The unit does not go into alarm mode if the received light inten-
sity varies.
• 50P (50%) : If no workpiece is detected, the unit goes into alarm mode when
the received light intensity lowers to the intermediate value
between the received light intensity and the set value.
• 0P (0%) : The unit goes into alarm mode when the level of received light
intensity lowers even slightly.
A 2-output type unit can output to the external devices that it is in the alarm
output mode with 2-output setting ( ).
For details, see "Warning output mode" (page 4-37).
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.
