Sensor Type Selection Screens: The Sensor Type you select for an input sensor automatically
P500
determines the setup parameters and values for each output that is set up to reference that sensor. See
Table 3 for information about System 450 sensors/transducers, Sensor Types, condition type, units of
Sn-1
measurement, minimum differential or proportional band, setup values, value ranges, and product code
numbers.
Note: For an output to operate properly, the selected Sensor Type must match the sensor/transducer
°F
model wired to the control module, and the sensor/transducer must be wired to the proper control module
input terminals.

Note: If your control system does not use three input sensors, simply press
flashing in a Sensor Type Selection screen to save no Sensor Type and go to the next setup screen.
4. In the Sn-3 Sensor Type Selection screen, press
Press
• go to the Temperature Offset Setup screen for the first temperature sensor in your system.
• return to the Sensor Setup-Start Screen, if your control system has no temperature sensors.
Screen examples show Sn-1 with the P500 Sensor Type selected; Sn-2 with the °F Sensor Type
selected; and Sn-3 with the no Sensor Type selected.
Temperature Offset Selection Screens: Select a temperature offset for the temperature inputs (only) in
-3
your control system.
Sensor Type °F enables an offset of +/- 5°F in 1 degree increments.
OFFS

Sensor Type °C enables an offset of +/- 2.5°C in 0.5 degree increments.
Note: The temperature offset changes the displayed temperature value by the selected offset value.
5. Press
• to go to the next Temperature Offset Selection screen (if there are additional temperature
sensors in your control system) and repeat this step for each temperature sensor.
• to return to the Sensors Setup-Start Screen.
Screen example shows -3 (flashing) is the selected temperature offset value for Sensor 2, thus a sensed
temperature of 75°F at Sensor 2 is displayed as 72°F.
Sensors Setup Start Screen: The Sensor Setup screens return to the Sensor Setup Start screen.
