,

Automatic teaching
The maximum and minimum light le-
vels are sampled while the input is ON 
and, when the input turns OFF, the 
average of these values is set as the 
threshold value.
Disabled if the detection function is set 
to "DIFF" (differential operation).

A

B

Output for each channel.

2OUT

AREA

Output if level is between the two  
thresholds.

SELF

The function of the output for channel 2 can be selected.
This setting is not value if DIFF (differential operation) 
is set for the detection method. (The output for channel
2 is always an alarm output for differential operation.)

7. Twin Outputs

(Twin-output Models Only)

The output for channel 1 functions according to the  
detection mode selection.

Self-diagnosis output
Output when the incident light le-
vel  
is not stable, i.e., when the light le-
vel is ±10% of the threshold value
