Span adjustment during differential mode
Time
Threshold
value
d-01
When setting differential mode in PRO mode, the maximum sensitivity (minimum
threshold value) is set.
If the response time is changed in differential
mode, the maximum sensitivity (minimum threshold
value) for that response time is set automatically.
Span adjustment for differential mode can be set
as follows in teaching mode. The threshold value
can be changed using the threshold value fine adjustment function. Refer to
‘threshold value fine adjustment function (P. 6)’ for details.

L/D ON : Output Operation Setting Mode
Refer to p. 22 for setting procedure
This mode allows the selection of output operation from either Light-ON, or Dark-ON.
* Products manufactured up until June 2004 (~ Lot No.: 4F

) are set in 5 steps (d-01 to d-05).
When using differential (rising or trailing) mode
For L-ON, the output turns ON when the incident light intensity is greater than the
ON level (2_SL), and the output turns OFF when the incident light intensity is less
than the OFF level (2_SL).
For D-ON, the output turns OFF
when the incident light intensity
is greater than the OFF level
(2_SL), and the output turns ON
when the incident light intensity
is less than the ON level (1_SL).

Only sudden changes in the light intensity are sensed, so that objects such as
glass edges can also be sensed with stability.
When set to ‘L-ON’, the output will be ON if the incident light intensity becomes
greater than the ‘threshold value’.
When set to ‘D-ON’, the output will be ON if the incident light intensity becomes
less than the ‘threshold value’.
When set to ‘L-ON’, if the incident light intensity is between the two ‘threshold
value’ levels, the output will be ON. If the incident light intensity is outside of the
two threshold value levels, the output will be OFF.
When set to ‘D-ON’, if the incident light intensity is between the two ‘threshold
value’ levels, the output will be OFF. If the incident light intensity is outside of the
two threshold value levels, the output will be ON.
