CHAPTER 1 ─ INTRODUCTION
1.1 About the ElNet Meter
Large consumers of electricity e.g. factories, hotels, hospitals,
municipalities, need to know the history of their consumption and
the quality of the power supply. Details such as Voltage, Current,
Power Factor, Hert , Neutral Current, Energy Demands and all
electricity related events are recorded in the ElNet Energy &
Powermeter.
An additional feature of the Meter is the ability to measure
Harmonics. Part of the Electricity Supply Authority’s bill reflects
poor or good Harmonics in the consumer’s system, therefore it is
in his interest to monitor Harmonics and try to improve it.
These are all recorded on a continual basis and can be recalled
and shown on the front panel display of the instrument with a few
simple key-strokes any time the user wishes.
The ElNet Energy & Powermeter is a compact, multi
functional, three-phase Meter simple to install and is especially
designed to integrate into Building Management Systems. It
requires no special mounting and is ideally suited for mounting on
the front face of any standard electrical panel.
The Configuration and Setup is menu driven, with password
protection.
Communication with external devices is simple and is based on
standard known technology.
The ElNet Energy & Powermeter boasts a new innovative
built in “Flash Memory”, which pioneers a new frontier into
electrical measurement. It has a 1 MB of FLASH MEMORY with
a capacity of recording up to 2 years of power malfunctions and
interruptions.

6
Readings, graphs, tables & history are shown on the graphic
display of the ElNet Energy & Powermeter . This display is
a state of the art screen with a resolution of 160X128.
Each ElNet Energy & Powermeter is carefully and
meticulously manufactured using quality components and the
latest production methods. Before leaving the factory each
ElNet Energy & Powermeter is calibrated and sent to the
customer accompanied by the test certificate and Certificate of
Compliance (C.O.C).
1.2 How to use this manua
We at CONTROL APPLICATIONS Ltd, envisage this manual to
be used by three types of people, i.e. the Installation Technician,
the Senior Electrical Engineer and the end User. For this reason
this manual is divided into chapters for ease of reference by each
of these different people. There could be a situation where two of
the abovementioned tasks can be combined, or in a rare instance
one person could handle all three tasks.
CHAPTER 1, Introduction, describes the ElNet Energy &
Powermeter , its potential users, the readings it can provide and
some of its features in brief.
CHAPTER 2, Installation, provides detailed instructions for
unpacking, mechanical mounting, and electrical wiring up
instructions for the Installation Technician.
CHAPTER 3, Using the
ElNet Energy & Powermeter,
describes in detail front Panel, the functions of the control
buttons, and the Lock Utility.

7
CHAPTER 4, Parameter Configuration & Settings explains in
detail the minimum parameters settings needed by the Senior
Electrical Engineer to set up and configure the ElNet Energy
& Powermeter.
CHAPTER 5, Front Panel Displays, is an easy to follow step-by-
step guide to obtain readings, graphs, tables and histories for the
User.
CHAPTER 6, Alarm reports gives details about how to program
the Alarms in the ElNet Energy & Powermeter.
CHAPTER 7, Demand reports is an easy to follow step-by-step
guide to obtain the Demand reports up to 2 years.
CHAPTER 8, Data Logging is an easy to follow step-by-step
guide to obtain all the stored peaks of current, voltage, energy,
power factor etc. up to 2 years of data logging.
CHAPTER 9, Communications gives details about the
Communication capabilities of the ElNet Energy &
Powermeter, and how to Set Up.
CHAPTER 10, Specifications, is a detailed list of specifications of
the ElNet Energy & Powermeter .
APPENDIX A, Installation & Configuration Check List, provides
