Inlet Pressure
Feedback
This output can be used to monitor the current value of the analog input for inlet
pressure on machines that have an inlet pressure sensor. The scaling of the output
matches the scaling of the inlet pressure sensor. For most machines, this is as follows:
4 mA = 0 bar absolute and 20 mA = 1 bar absolute.
Airend Temperature
Feedback
This output can be used to monitor the current value of the temperature input for
airend discharge temperature. The scaling of the output is linear between 0 degrees C
and the factory maximum fault setting. On most machines, this will be equal to: 4 mA =
0 C (32 F) and 20 mA = 115.56 C (240 F).
Percent Load
Feedback
This output can be used to monitor the current value of percent load on a variable
speed machine. The scale of the output is linear between 4mA = 0% load and 20 mA =
100% load.
