[S7] Detection
Selectable Options
Selectable option Function description
Positive Output is generated when the received light amount increases.
Negative Output is generated when the received light amount decreases.
Both (default value) Output is generated when the received light amount increases or decreases.
4-6-9 [S7] - [D9] Edge offset
This menu sets the interval in which to compare difference in the received light amounts with Edge mode.
This setting parameter is only displayed when Threshold mode ([S7] - [D2]) is set to Edge height.
For details on Edge height, refer to “3-7-5 [S7] - [D2] Threshold Mode “Edge height”” (page 3-47).
Selectable Parameters
The Edge offset that can be set varies depending on the “[S3] Response time” setting. Before setting Edge
offset, set “[S3] Response time” appropriately.

Selectable when “Response time” is set to 250 µs
0.5 ms to 127.5 ms (default value:
5.0 ms)
Selectable when “Response time” is set to 500 µs
1 ms to 255 ms (default value: 10 ms) Selectable when “Response time” is set to 1 ms
2 ms to 510 ms (default value: 20 ms) Selectable when “Response time” is set to 2 ms
8 ms to 2040 ms (default value: 80 ms) Selectable when “Response time” is set to 8 ms
*1: For a stand-alone unit, and inter-connection main unit with stand-alone use
*2: For main and expansion units when connected
4-6-10 [S7] - [DA] Edge hys.
The Edge hys. (edge hysteresis) is a function to set a hysteresis between the amounts of light received when
the output is turned on and the output is turned off in the Edge mode.
Each change (difference) in received light amounts is called as follows, and the range between the
differences in received light amounts is called hysteresis.
• Operation difference: Turn the output on when the change of received light amount reaches the difference
• Reset difference: Turn the output off, while the output is on, when the change of received light amount falls
below the difference
