Via the SX Tool

The input type for the eight possible inputs (n = 1 to 8) can be configured in Item AITn (RI.88, RI.96, RI.104, RI.112, RI.120, RI.128, RI.136, and RI.144).

The unit of each analog input can be selected with following bits: (For RTD inputs, Celsius or Fahrenheit must be selected.)

X4 X3 X2 X1 = 0000	No Units
X4 X3 X2 X1 = 0001	Celsius
X4 X3 X2 X1 = 0010	Fahrenheit
X4 X3 X2 X1 = 0011	Percent

Changing individual temperature units for each AI can only be done in the SX Tool.

This function allows the linearization of the differential pressure signal from a 0-10 VDC or 0/4 - 20 mA active sensor; the function is effective over the selected range:

AI = sqrt(PR%/100) * (HR - LR) + LR

Where %PR = the Analog Value in % of the physical input range; HR = High Range Value; and LR = Low Range Value.

Via the GX Tool (Option Only Available with Active Sensor)

Select XTn, AIn, and Data. At the “Square Root” field, enter “0” for No, or “1” for Yes (to enable the square root calculation).

Via the SX Tool (Option Only Available with Active Sensor)

Select Item AITn.

X5 = 1 Enable Square Root of Input
