Parameters 221
Direct temperature The temperature is taken from the source selected by
parameter 35.14. The value of the source is assumed to
be degrees Celsius.
11
KTY83 analog I/O KTY83 sensor connected to the analog input selected by
parameter 35.14 and an analog output. The analog input
can be from the standard I/O or from an extension
module.
The following settings are required:
• Set the hardware jumper or switch related to the analog
input to U (voltage). Any change must be validated by a
control unit reboot.
• Set the appropriate analog input unit selection
parameter in group 12 Standard AI to V (volt).
• In parameter group 13 Standard AO, set the source
selection parameter of the analog output to Temp
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.
12
1 x Pt1000 analog I/O Pt1000 sensor connected to a standard analog input
selected by parameter 35.14 and an analog output.
The following settings are required:
• Set the hardware jumper or switch related to the analog
input to U (voltage). Any change must be validated by a
control unit reboot.
• Set the appropriate analog input unit selection
parameter in group 12 Standard AI to V (volt).
• In parameter group 13 Standard AO, set the source
selection parameter of the analog output to Temp
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.

2 x Pt1000 analog I/O As selection 1 x Pt1000 analog I/O, but with two sensors
connected in series. Using multiple sensors improves
measurement accuracy significantly.
14
3 x Pt1000 analog I/O As selection 1 x Pt1000 analog I/O, but with three sensors
connected in series. Using multiple sensors improves
measurement accuracy significantly.
