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, Hertz, 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 manual
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

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-bystep 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

instructions carefully before performing any installation and note
any precautions.
• Ensure that all incoming AC power and other power
sources are turned off before performing any work on
the
ElNet
Energy & Powermeter. Failure to do so
may result in serious or even fatal injury and/or
equipment damage.
• If the
ElNet
Energy & Powermeter is damaged in
any way do NOT connect it to any power source.
• To prevent a potential fire or shock hazard, never expose
the
ElNet
Energy & Powermeter to rain or
moisture.
• Keep the surrounding area free of dirt and clutter
especially metal objects. Good housekeeping pays.

2.4 Rear Panel Connections
Please re-read section 1.3 for safety instructions.
To connect the Rear Panel
All Connections, except those to the CT core of the
ElNet
Energy & Powermeter are made via terminal connector plugs
(Voltage input, Power Supply, Communication etc.).
Maximum recommended tightening torque for the connector screws
is 0.5 Nm.
The CT cores of the
ElNet
Energy & Powermeter are
located externally on the rear of the instrument and the lead from
the leg of the external Current Transformer must pass through in
the correct direction.
NOTE!
Ensure all the connections to the leads of the current
transformer wiring are secure and there is no mechanical
strain on the wire. The cross section of the leads to the
current transformer must be compatible to the power of the
current transformer. We recommend a power transformer
with at least 3VA and the length of the wiring of the
transformer no longer than 3m.
22
Insert the lead from side “K” of the Current Transformers of Line
1 through the bottom of the CT core
I
1A, (top left looking from
back), of the
ElNet
Energy & Powermeter.
ARNING
Repeat the procedure for Line 2 and Line 3 (In ElNet PQ repeat
also for Neutral Line IN).
Connect the rest of the connections to the
ElNet
Energy &
Powermeter by means of terminal connector plugs.
The Rear Panel (See Figure 2.7.) has all connections printed and
are simple to follow. (See table 2-1 for connections)
• Ensure the leads from leg “K” of the Current
Transformer on Line 1 pass through the bottom of
CT core I1A.
• Ensure the other end of the lead emerging from the
top of C T core I1A is connected to leg “L” of the
Current Transformer on Line 1
WARNING!
Never allow an open circuit between the two Current
Transformers.

2.5 Digital Outputs and Inputs.
ElNet GR/PQ
Energy Powermeter & Power Quality
Analyzer has as default 3 Digital Output and 5 Digital Input
connections at its back side (additional IO can be implemented by using
additional external modules).
Digital Output:
The Digital Output of the GR/PQ can be used to transmit pulses of
energy to external BMS controller (chapter 4.6) or to close contact upon
alarm (chapter 5.4.3) which can be defined in the GR/PQ (same output
cannot be used for both simultaneously). The Digital Out closes contact
of Relay between pins 1/2/3 to 4c, the maximum load is 1 Amp.
Digital Inputs:
In order to change the status of the Digital Inputs of the GR/PQ a 220
VAC contact must be provided. The indication voltage should be
supplied from one of the measured phases. The digital inputs status can
be monitored by communication.
