On occurrence of an error message (E15, E16, E17, E18), the output current can be matched to 3 mA or
21 mA with the help of parameter SE, see Chap.

Examples:
The distance of a moving target is to be measured in a range of 2 m up to 6 m. At a distance of 2 m the sen-
sor is to output 4 mA. You find the parameter RB and RE against SF below:
- RB2 / RE6 / SF1
The distance of a moving target is to be measured in a range of 1 m up to 21 m. At a distance of 1 m the sen-
sor is to output 20 mA. You find the parameter RB and RE against SF below:
- RB21000 / RE1000 / SF1000
