1.1 Product Description
The GE Multilin EPM 5100 Electronic Power Meter is a full-function electronic meter with
optional pulse initiation and communications features. The communications option
supports the ‘open-architecture’ Modbus protocol and can be easily installed in the field at
a later date. The EPM 5100 is available with the following mounting options:
• An industry-standard SI-compatible case to maintain drawout capability, allowing
for easy upgrade or retrofit from existing DS-63, DS-64, or DS-65
electromechanical watthour meters (case type unit).
• A light compact plastic enclosure for panel mounting (panel mount unit).
The EPM 5100 continuously monitors specified line characteristics and displays the desired
functions and calculated values on a two-line, alphanumeric liquid crystal display (LCD) on
the front panel. The meter samples each of the current and voltage inputs 480 times per
second, and the display is updated every three seconds.

CHAPTER 1: OVERVIEW
FIGURE 1–1: EPM 5100 Meter
Metered and calculated values appear
on the two-line liquid crystal display. The
value appears first, followed by the
paramter name. The parameters appear
in the order listed on the inside of
the door.
Press the SELECT ENTER key to switch
between normal and alternate scroll in
Metering mode or to select functions and
options in Program mode.
Press the SCROLL keys to scroll through
the metered functions in the Metering mode
or through the menus of functions and
options in the Program mode.
Open the door at the bottom of the front
cover to adjust the display contrast or to
view the list of measured parameters.

1.2.2 Power Management Features
The EPM 5100 is available with the Power Leader communications options cards (catalog
number PLA3CMAG01 for Modbus RTU). The Modbus option provides the following
additional features:
• Remote viewing of all metered functions and configuration data at the host
computer.
• Graphical trending of most metered functions.
• User-defined remote alarms.
• Extensive reporting capabilities, including dynamic data exchange (DDE) for
exporting data for analysis by external software.
