CHAPTER 1 ─ INTRODUCTION

1.1 About the ElNet Pico Powermete

Large consumers of electricity e.g. factories, hotels, hospitals,

municipalities, need to know the history of their consumption and

the quality and the values of the power supply. Details such as

Voltage, Current, Power Factor, Hertz, Neutral Current, Energy

consumption can be displayed by the ElNet Pico Energy

Powermeter

An additional feature of the Multimeter is the ability to measure

THD –Total Harmonic Distortion. 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.

The ElNet Pico Energy Powermeter is a compact, multi

functional, three-phase Powermeter 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 DIN rail 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 protocol.

Each ElNet Pico Energy Powermeter is carefully and

meticulously manufactured using quality components and the

latest production methods. Before leaving the factory each

ElNet Pico Energy Powermeter is calibrated and is 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

of these different people. There could be a situation where two of

the above mentioned tasks can be combined, or in a rare instance

one person could handle all three tasks.

CHAPTER 1, Introduction, describes the ElNet Pico

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 Pico Powermeter, describes

in detail front Panel, the functions of the control buttons, and the

Lock Utility.

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 Pico

Energy Powermeter.

CHAPTER 5, Front Panel Displays, is an easy to follow step-by-

step guide to obtain readings and tables.

CHAPTER 6, Communications provides details about the

Communication capabilities of the ElNet Pico Energy

Powermeter, and how to Set Up.

CHAPTER 7, Specifications, is a detailed list of specifications of

the ElNet Pico Energy Powermeter.

1.3 Safety Information

The purpose of this manual is to help you. Please read the

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 Pico
