Figure 3-15. Wiring Diagram for Temperature Inputs
When selected for resistive sensor, three additional shunt resistors are provided
to match the impedance range of the given sensor, to provide more range and
accuracy.
These inputs are designed to work with a variety of manufacturer’s sensors.
Sensors can have a Direct or Indirect relationship.
 Direct—Increase in Resistance, mA, or volts is an Increase in Pressure
or Temperature.
 Indirect—Increase in Resistance, mA, or volts is a Decrease in Pressure
or Temperature.
You must verify how the sensor functions so you can calibrate correctly. The
Calibration menu explains adjusting the Gain and Offset for the different sensors.
