using the self trigger level.
UP (Rise) / DOWN (Fall)
[Default: UP]
Self trigger delay
(SLF.DLY)

0 to 199.9999 (mm)
[Default: 1000]
After exceeding or falling below the specified self trigger level (depending on the specified self trigger edge
direction), the judgment value is held automatically on expiry of a period specified by the delay timer.
Fulfillment of the above condition activates self triggering, which updates the judgment value. Until that time,
the output continues to be held.
Note
An indefinite state is held on occurrence of any of the following:
The power is turned ON
The reset input is ON
A sensor head disconnection error or upthrust error (alarm) is canceled
If the input value falls below the self trigger level before the time set by the delay timer has elapsed,
the controller enters an alarm state. (In the case of the self trigger edge direction being set to UP)
