NOTE!
The analog input can only be used as an alternative to digital input 2 with signal type 0(2) up to 10 V.
Resistance Ra or Ro, Rs or Rx, Re
The overall resistance Ra + Rs + Re (or Ro + Rx) must not exceed 4000 Ω.
Filter time constant
The filter time constant is used to adjust the digital input filter (2nd order filter). If the input signal changes
suddenly, approx. 26 % of the change is recorded following a period that corresponds to the filter time
constant (2 × filter time constants: approx. 59 %; 5 × filter time constants: approx. 96 %). A large filter
time constant means: high attenuation of interference signals, slow reaction to the actual value display,
low limit frequency (low-pass filter).
7.5.1 Fine adjustment
You can use this function to correct the measured values of the analog input. In contrast to measured
value offsetting, which is used to specify a constant correction value for the entire characteristic line, fine
adjustment can also be used to change the gradient of the characteristic line.
Actual start value -1999 to 9999 (0) Fine adjustment: device measured value at the
lower measuring point
In contrast to measured value offsetting, which is
used to specify a constant correction value for the
entire characteristic line, fine adjustment can also
be used to change the gradient of the characteris-
tic line.
Actual end value -1999 to 9999 (100) Fine adjustment: device measured value at the up-
per measuring point
Target start value -1999 to 9999 (0) Fine adjustment: reference value at the lower mea-
suring point
Target end value -1999 to 9999 (100) Fine adjustment: reference value at the upper
measuring point
