Did You Know? If the total system power factor is less than 0.55, the LEDs will be red even if connected properly. This situation is rare but could occur if, for example, the load to be monitored is a lightly loaded electric motor where it is common for the power factor to be less than 0.55 and the corresponding LEDs will be red. C.2 Power Meter Configurations Using ViewPoint C.2.1 Installing the ViewPoint Software The ViewPoint software is designed to allow for easy configuration of the 56WM for different current transformers, check readings, and verify correct setup. The 56WM uses ViewPoint software to communicate with the meter. It needs to be installed on any computer communicating with the 56WM. ViewPoint is compatible with Windows 7 (32 or 64 bit), Windows 8 Pro, Vista (32 or 64 bit), or XP. Start the installer by double-clicking ViewPointInstaller_4.exe. The communication screen is displayed when ViewPoint is first started. ViewPoint software serves several functions, such as setting up a meter, getting real-time values, and read/write registers and objects, but for the purpose of prepping for field installation only three are important to the process: Communications and Meter Setup. The other functions are described later in this document. 56WM User Guide 25

C.2.2 Connecting a Communication Cable A USB cable can be used to power and communicate with the 56WM. When using a USB cable with a PC, each USB port on the PC generates a unique COM port in the ViewPoint software. For Communication: Select USB/RS-485. In the PC COM Port: drop down menu, select COMxx DENT USB (COMxx) to communicate with the 56WM. The meter will start communicating to the ViewPoint by pressing the Connect button. The Model Number, Serial Number, and Firmware Version will appear to confirm the connection is open. NOTE: A USB driver is installed when you install the ViewPoint software. 26 56WM User Guide

C.2.3 56WM Setup Once communication is established between the PC and the 56WM, the device is ready to be configured for the field. This is accomplished in the Meter Setup tab of ViewPoint. The settings for the 56WM can be viewed by clicking on Retrieve Meter Setup. The Meter Setup screen allows unique changes to an element on the 56WM. Within the element, CT Phase, Type, Amps, and Phase Shift are entered, based on wiring connection, for CT1, CT2, and CT3. The type of wiring connection is also entered for the element. Overall, a demand window of 1 60 minutes is available for the recording of values and a line frequency of 50 Hz or 60 Hz is selectable. NOTE: For the 56WM, peak demand is calculated using a moving average across the selected demand window size. Each minute the total consumption is recalculated and compared to the last demand window. If the new window is larger than the last recorded value it is recorded. This value is calculated during the sampling of the waveform. 56WM User Guide 27

C.2.4 Current Transformer Setup Begin setup by entering an amount of time (1-60 minutes) into the Demand Window and selecting a line frequency from the drop-down list. NOTE: The default time is 15 minutes. Use the following steps within an element: 1. Depending on the wiring connection, make changes to CT1, CT2, and/or CT3.
