Connecting the positive and negative wires from the third-party device to

Terminals 1 and 2 (analog input terminals) on the I/O terminal block

 Connect the other ends of the positive and negative wires

to the third-party device based on the vendor’s

specifications.

 Close and latch the door to the XIO.

4. Restore power to the customer’s instrument or device and the

ADS XIO.

5. Verify that adding the ADS equipment will not add too much

load to the analog signal loop. The XIO input adds 22 ohms to

the loop. If too much load is added, the signal will clip and

cause the data to flat line at a lower level than the true peak,

which will result in understated peak levels or flows. If only

one device is connected to the analog signal, sufficient current

is probably available to drive the XIO input. If more than two

devices are attached to the analog signal loop, ADS strongly

recommends load testing the loop.
