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 
b
etwe
en the received light int
ensity 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.
