Fig. 14 Digital switching output behavior with positive and negative hysteresis
Example:
A moving object is assumed to be monitored within a window of 10 m to 11 m with a hysteresis of 0.2 m.
Consecutively you find the parameters AC, AW and AH in dependence on SF:
- AC2 / AH0.2 / AW3 / SF1
- AC2000 / AH200 / AW3000 / SF1000

How the switching output is to behave on occurrence of an error message (E15, E16, E17, E18) can be de-
fined by making suitable settings under “SE“, see Chap.
