Wiring Diagnostics
The PowerMonitor 1000 and PowerMonitor 5000 units provide advanced wiring diagnostic features that provide a
means for you to verify proper PowerMonitor unit connections and diagnose wiring errors. To meter power and energy
correctly, voltage and current inputs must be connected to the power circuit with the correct phase rotation and polarity.
Indications of wiring errors include the following:
Indication of negative real power (kW) on a load, or indication of positive power on a generator
Power factor outside the appropriate leading and lagging range
In addition to the wiring diagnostics, the PowerMonitor 5000 unit also offers a wiring correction feature. This feature
affords you the ability to correct any wiring virtually. You can perform wiring diagnostics and correction through the
embedded webpage and the device configuration window in FactoryTalk EnergyMetrix software.
Analyze the Data
The first layer in the foundation for accurate collecting and reporting of energy data is to monitor the energy data. When
you analyze this information, you can make better decisions around controlling costs and reducing power quality issues.
For this energy data information to make a difference in operations, it must seamlessly integrate into a connected
enterprise. To maximize the benefits of an energy management program, you have to coordinate the combination of
power monitoring, control devices, communication networks, and visualization technologies into a unified system that
relates energy consumption to plant activities.
Embedded Webpages
Both the PowerMonitor 1000 and PowerMonitor 5000 units have built-in webpages that allow for quick and easy access
of energy and power quality data over an Ethernet network. A connection to the embedded webpage is made by entering
the IP address of the PowerMonitor unit into an internet browser window. With a click, all data parameters are available.
The embedded webpage also provides another means for configuring the PowerMonitor unit, which is useful when
commissioning an energy management solution. During the commissioning process, you can open the webpage to view
wiring diagnostic data to verify that the unit is wired correctly. Parameters such as line voltage, current, and power factor
can be monitored to confirm that the PowerMonitor unit is metering accurately. Data logs can also be exported from the
webpage and analyzed for demand management or power quality control.
