Calibrate Voltage for the Bus Run
Voltage is uniform throughout the bus run. To calibrate actual voltage, measure voltage with a voltmeter
at the power feed
’s Starter Rail
: A-B, B-C, C-A, A-N, B-N, and C-N. Enter the data in the corresponding
boxes.
•
Click
Set Voltage
to enter these measurements into the point list for all Tap Off Boxes.
•
Click
Clear
to blank all fields on this setup page and re-enter data.
If calibration data is not entered, the standard voltage from the voltage type is used.
These buttons clear Alarms, Min-Max Measurements, and KWH accumulations during setup:
•
Clear Alarms
•
Clear Min/Max
—
sets the minimum and maximum current measurements to the most recent
current measurement value.
•
Clear KWH
—
sets KWH accumulation to 0.
You should clear these values when exiting setup to set the monitoring system to an initial production
state. You can also clear any of them for testing during setup.

Flip Current for Strip 1: Tap Off Boxes have (2) CT strips, each measuring current on (3) poles. If
CTs are attached to 3-phase ABC (L1-L2-L3) circuit wires in reverse order (CBA), check this box
to correctly align measurements with circuits on CT strip 1.
