224 Parameters
Ni1000
Ni1000 sensor connected to the analog input selected by
parameter
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
to
V
(volt).
• In parameter group
, set the source
selection parameter of the analog output to
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.
16
PTC analog I/O
PTC sensor connected to analog input selected by
parameter
and an analog
output.
The required settings are the same as with selection
Note:
With this selection, the control program converts the
analog signal to PTC resistance value in ohms and shows
it in parameter
. The parameter name and unit still
refer to temperature.
