Setting Description
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 option Function description
16 µs to 4080 µs (default value: 160 µs) Selectable when “Response time” is set to 16 µs

*2: Main and expansion units connected
MEMO
The default value of Edge offset is set to 10 times the value of Response time (the received light amounts at present and
at the time before multiplying response time by 10 are compared). Changing Edge offset adjusts the duration to compare
as follows.
• Shorter Edge offset
Performs comparison with the recent received light amount.
Setting the shortest time performs the comparison with the previous received light amount.
• Longer Edge offset
Performs comparison with a received light amount from a longer time before the present value.
Setting the longest time possible compares with the data from 255 times before the present received light amount.

Edge hys. ([S7] - [DA])
Change this setting to adjust the hysteresis to turn the output on and off with the Edge height mode.
