Description
KTY84 sensor connected to the analog input selected
35.14 Temperature 1 AI source
by parameter
analog output.
The following settings are required:
• Set the appropriate analog input unit selection
parameter in group
• In parameter group
selection parameter of the analog output to
sensor 1 excitation
.
The analog output feeds a constant current through
the sensor. As the resistance of the sensor increases
along with its temperature, the voltage over the
sensor increases. The voltage is read by the analog
input and converted into degrees.
Pt100 sensor connected to a standard analog input
selected by parameter
and an analog output.
The following settings are required:
• Set the hardware jumper or switch related to the
U
analog input to (voltage). Any change must be
validated by a control unit reboot.
• Set the appropriate analog input unit selection
parameter in group
• In parameter group
selection parameter of the analog output to
