The thermoresistor LG-Ni1000 corresponds to the thermoresistor Ni1000 with the temperature coeffi­
cient 0.005
NOTE
For a thermoresistor, the climatic type is only possible with temperature units Celsius (°C) and
Fahrenheit (°F).
10.1.4 Parameter description analog input
Group diagnostics
You can generally enable and disable the diagnostics function of the device with this
parameter.
The "Fault" and "Parameter assignment error" diagnostics functions are always independent
of the group diagnostics.
Diagnostics: Missing 1L+
If you enable this parameter, the check for missing supply voltage is enabled.
Diagnostics: Short-circuit sensor supply
If you enable this parameter, a diagnostics event is generated if a short-circuit of the sensor
supply to ground is detected and the channel is enabled. The sensor supply is monitored for
connectors X1, X3, X5, and X7. No differentiation is made as to the connector where the
sensor short-circuit occurred.
Interference frequency suppression
With this parameter, you set the integration time of the device, based on the selected
interference frequency. Select the frequency of the supply voltage used. Interference
