Cable Type
The light intensity may not be set to "
" when the reflective model sen-
sor head is first installed.
In this case, using the zero shift function to set the state with no target
present to "
" will make it easier to see the difference in light intensi-
ties.
•
When LV-S31 is connected

ON) or
(side nearer the sensor is ON) can be selected.
•
When using the 2-output type, output 1 and 2 can be set indi-
vidually.
