Input Signal

Range

An alarm from the High Limit (HIAn) and Low Limit Alarm (LOAn) will be generated from the unfiltered or filtered input. (See Filter Time Constant.)

Via the GX Tool

Select XTn, AIn, and Data. At the “Alarm Unfiltered” field, enter “0” for No (Alarm on Filtered Value), or “1” for Yes (Alarm on Unfiltered Value).

Via the SX Tool

Select Item AITn.

X6 = 0 Alarm on Filtered Value

X6 = 1 Alarm on Unfiltered Value

Via the GX Tool

(You must first have selected whether the input is active or passive. See the beginning of Analog Input--Configuration.)

For active inputs, select XTn, AIn, then Data. At the “Type of Active Input” field, enter:

0 = 0-10 VDC

1 = 4-20 mA

2 = 0-20 mA

Each analog input module channel performs the conversion of the input signal to a numeric value using the high range and low range.

Select XTn, AIn, then Data.

High Range = enter the equivalent number for reading at high input (10V, 20 mA)

Low Range = Enter the reading at low input (0V, 0 mA, 4 mA)

For passive inputs, select XTn, AIn, then Data. At the “Type of Passive Input” field, enter:

1 = Ni1000 (JCI Type)

2 = Ni1000 Extended Range

3 = A99 (JCI Type)

4 = Pt 1000 (DIN)

Note: Selections 5 and 6 on the screen are not available in the XT-9100.

For RTD inputs, the range of the displayed value is fixed according to the type of sensor.
