Input 6 to which a potentiometric transducer is connected features a particularity: only the wiper resistance rather
than the overall resistance is measured. For this reason, the internal parameter setting and calculation of the input 6
transducer is not identical with the one of input 1.

These calibration values belong to the engineering, i.e. when replacing the instrument, the user calibration remains un -
changed. As a prerequisite, it has to be re-loaded into the engineering after calibration.

Standard 0/4...20 mA current input

The input resistance is 50 [

During configuration, distinction between 0...20 mA and 4...20 mA is made. For standard 4 ... 20 mA signal, the signal
behaviour with sensor break can be defined (

Fail). Additionally, physical input signal scaling using a defined value

of

X0 and X100 is possible. For measured value processing, a filter time constant with a numeric value within 0,0

and 200000 can be adjusted (r

Tfm)

DINPUT ( digital inputs (No. 121))

Function ‘DINPUT’ is used for digital input configuration and parameter setting. The function is assigned firmly to block
number 91 and is calculated invariably in each time slot. Inversion of each individual signal can be configured. If in -
puts di3...di12 are provided is dependent of the KS 98-1 hardware option.
