Multiple function of the analog and digital inputs

Analog inputs 1 and 2
The analog inputs have several functions:
● Under "P-ANALOG INPUTS/Analog input 1/AI-function" you can set the value from
"Analog" to "PTC", "KTY84" or "PT100".
● Under "P-ANALOG INPUTS/Analog input 2/AI-function" you can set analog input 2 from
"Analog" to "PTC", "KTY84" or "PT100".
● Also adjust the corresponding DIL switches of the -S2 switch row on board CB08
● More detailed information can be found in the section "DIL switches S1 and S2
(Page 149)".
The following functions are now available:
● "Analog":
The analog input operates as a voltage input at control cable terminals -X2:52-51 / 54-51
or as a current input at control cable terminals -X2:50-51 / 53-51 The value is available as
"AI 1" or "AI 2" for further processing.
● "PTC":
The analog input operates as a PTC thermistor input at control cable terminals
-X2:50-51 / 53-51. The PTC thermistor state is available for further processing as
selection bit "PTC AI 1" or "PTC AI 2".
● "KTY84":
The analog input operates as a direct input for a KTY84-130 temperature sensor at
control cable terminals -X2:50-51 / 53-51. The measured temperature is available as an
analog value under "T-AI1" or "T-AI 2" for further processing.
● "PT100":
The analog input operates as a direct input for a PT100 temperature sensor at control
cable terminals -X2:50-51 / 53-51. The measured temperature is available as an analog
value under "T-AI1" or "T-AI 2" for further processing.
Any analog input can only be used for one function. It is not possible to use several functions
simultaneously for one input.
