1 INTRODUCTION
This instruction manual describes the procedures for installing, connecting, checking and
maintaining the MTL4850 HART
®
maintenance system, which is a simple interface between
smart devices in the field and HART instrument management software running on a PC.
The following sections are outlined here.
Section 2 describes the system and the solutions available
Section 3 covers some safety aspects.
Section 4 deals with the installation of carriers and mounting backplanes
Section 5 describes installing and configuring the modules
Section 6 provides information on fault finding, and maintenance
Section 7 introduces software for the MTL4850 System.
See the MTL web site (www.mtl-inst.com) for the full specifications of the MTL4850 system
components and accessories, and the MTL4500 Series isolators mentioned in this manual.
2 DESCRIPTION
The MTL4850 HART Maintenance System enables a user to calibrate, configure and maintain
an entire network of 'smart' field devices from a single workstation.
The key element that makes this possible is the MTL4850 or MTL4854 modules, which provide
the multiplexing for the individual field devices, making each one addressable and identifiable
from the workstation.
The other important element is the terminal circuit board that simplifies the interconnection
of the field devices to the multiplexer module. A range of terminal boards and backplanes has
been designed to suit most general applications but custom versions can also be designed to
suit individual OEMs and their applications.
