configuration of Power Advisory

main screen

The Power Advisory configuration screen allows users to characterize the

loop and configure the Terminal Voltage Deviation Limit and the Action. Two

instances of loop characterization data are recorded and presented on this

screen: “Baseline” and “Previous Baseline”. Baseline represents values from

the most recent loop characterization whereas Previous Baseline represents

values recorded prior to the most recent characterization.

Terminal Voltage

This field shows the current terminal voltage value in Volts. The terminal

voltage is a dynamic value and is directly related to the mA output value.

Terminal Voltage Deviation Limit +/-

The Terminal Voltage Deviation Limit should be set large enough that

“expected” voltage changes do not cause false failures. The default value of

1.5V will accommodate typical deviation of customer power supply voltage

and loop tests (amp meters connected across the test diode on the terminal

block). This value should be increased if your loop has additional “expected”

variation.
