1.7.5.3 Wiring a 0/4-20 mA Analog Inputs Option Card (cont.)
Wire the analog inputs as shown on the label in the rear cover (see Figure 3 on page 6 and Figure 11 on page 24).
Note: The analog inputs option card can be calibrated with the Model XMT868i’s built-in analog outputs. However,
be certain that the analog outputs have been calibrated first. See Chapter 1, Calibration , in the Service
Manual for the appropriate procedures.
1.7.5.4 Wiring a Totalizer and Frequency Output Option Card
Each totalizer and frequency output option card provides two or four outputs (designated as A, B, C , and D ).
Wire this option card in accordance with the connections shown on the label in the rear cover (see Figure 3 on
page 6 and Figure 11 on page 24). Figure 6 shows sample wiring diagrams of a totalizer output circuit and a
frequency output circuit. Refer to Electrical Specifications on page 3 for the load and voltage requirements.
