Operation

5.4.4Main Breaker Status

The Main Breaker Status area displays RMS current, percent load (PCT), total harmonic distortion (THD), crest factor (CF), line-to-line voltage (VLL-RMS), line-to-neutral voltage (VLN-RMS), instan- taneous power (Power), VA and power factor (PF) for each input phase. If any phase voltage or cur- rent is in alarm, the associated field displays white text with a red background.

Metered energy usage for the panel

The metered energy usage for the panel is also displayed in kilowatt hours (kWh), as shown above. To clear all metering information, click the Reset All kWh button.

! CAUTION

Exercise care before using the Reset All kWh button, which resets the kWh usage for the main breaker as well as all branch breakers and subfeed breakers on the panel.

5.4.5Breaker Status

The Breaker Status area displays detailed status for every branch or subfeed breaker on the selected panel. The information may appear in a table or as icons, depending on the whether the Table or Icons button is active (see 5.4.6 - Mode Buttons).

The example below shows the table format with details for each breaker: type and rating, percent load, individual phase current in amps (I1, I2, I3), power, apparent power (VA), power factor (PF) and accumulated kilowatt hours (kWh.)

5.4.6Mode Buttons

Mode buttons at the bottom of the Monitor window allow users to download Monitor readings to a file, toggle the display between branch and subfeed breakers, toggle between table and icon views of breaker status data and view the Event Log. Additionally, Emerson Network Power technical person- nel may control the auto-zero function if the diagnostic registry key is installed.
