7.2.4 Setting the analog signal type on S4 and S7
The position of the jumpers on pin headers S4 and S7 determines the current analog signal type
(see “4.4.1 Analog input X3” on page 19).
7.3 Analog input
Note
●
If a signal exceeds or falls below a boundary value at analog input X3-S, the temperature set-
point 23 °C is transferred. (see “5.3.4 Signal boundary value monitoring” on page 27)
●
Analog input X3-S is only evaluated if a signal is applied to digital input X2b-D4 (see “5.1
Functions of analog input X3” on page 23).
