1Introduction

This manual is intended to provide guidance for the installation, operation and maintenance of the HiD 2000 range

of intrinsic safety isolators.

To avoid damage, failure or improper operation, carefully read this manual before installing and operating the unit.

This manual and the related equipment should not be used by untrained personnel unless they are fully acquainted

with the principles of intrinsically safe system.

Elcon Instruments has published a complete tutorial entitled “Guide to Intrinsic Safety” covering most aspect of

intrinsic safety. The book can be obtained from Elcon Instruments free of charge.

1.1 Overview

The Elcon HiD 2000 Series is designed to be used in connection with process instrumentation system and consist

of a range of compact I.S. isolating interface modules to handle the input and output signals of a process plant.

Moreover a range of standard and custom made Termination Boards are available where the modules can be

plugged and quickly secured.

With this new full line of modular plug-in I.S. isolator a significant cost reduction is achieved in project planning,

plant design commissioning and service.

The module pack one, two or four isolated channels into a compact housing which can be inserted or removed

from the Termination Board without disturbing any of the wiring, no specialist knowledge is required, thereby

eliminating a frequent source of errors. The new “Quick Lok” method of fixing the module without the need for

tools reduces installation time and is very ease to operate. Pushing down a tab on each side of the module rotates

a securing foot which locks the unit to the Termination Board; to remove the modules simply lift the tabs. For

servicing, only the defective module needs to be removed and the replacement module plugged into the

Termination Board and locked by the quick mechanism. No special knowledge is required, the signal cables don’t

need to be detached and re-connected, eliminating a frequent source of errors.

Polarisation on the Board securely prevents modules from being swapped inadvertently.

The HiD 2000 Series product range has:

•high packing density, due to innovative circuit design using advanced surface mount components

•high performance, with high signal transfer accuracy and repeatability, low consumption, low heat

dissipation

•wide functionality, with a wide range of I/O signals, galvanic isolation, line fault alarm

•HiD 2000 Series products are Intrinsic Safety Certified according to CENELEC, CSA, FM, GOST, SEV,

SABS, SAA and other world-wide standards. Moreover, they meet European directives on EMC, and all

modules carry the CE marking.

1.2 Explanation of Contents

This instruction manual describes how to install, connect, check and maintain the HiD range of intrinsic safety

isolators:

•section 2 supplies the technical specifications of the units in a concise form

•section 3 describes system operation.

•section 4 describes how to install and configure the HiD modules

•section 5 shows how to operate the units

•section 6 deals with maintenance and troubleshooting issues

A Glossary and an Analytical Index for easy reference to topics complete the document.

This isolators manual is intended to be read and used in conjunction with the Termination Board User

Instruction Manual (IM-ENG 112/GB).

•loop identification, coding and tagging

•accept DC power supply over a wide range (24V, -15% +25%)

1.4 Hazardous Area Interfacing

Correct and safe operation of Elcon HiD 2000 Series calls for expert installation and commissioning as well as

correct operation and meticulous maintenance.

Only those persons conversant with the installation commissioning, operation and maintenance of similar

apparatus and who has the necessary qualifications are allowed to work on HiD 2000 Series.

Make sure installation is carried out observing the safety regulations pertaining to the installation and operation of

electrical system and the directives and guidelines on explosion protection (Hazardous Area equipment should

comply with the descriptive system document).

The installation must be performed by qualified personnel, it must comply with the relevant national/international

standards (e.g. IEC 79-14, CEI 64-2, BS 5345 Pt. 4, DIN VDE 165) and in line with the established installation

rules and recommended practice (e.g. CEI 64-8, ANSI/ISA RP-12.6).

The conformity of hazardous area devices with the related system documentation must always be checked. This

instrumentation IS NOT intended for hazardous area installation, unless it is included in a proper explosion proof

enclosure which conforms to the applicable standards.

For I.S. applications, the maximum limit for AC power supply is 250 Vrms.

For more information on request Elcon will provide the manual “Guide to Intrinsic Safety”, a comprehensive

tutorial about the constraints imposed by the I.S. regulations.
