1. About this document

General purpose

This document is the Operator’s Manual for THOMSON TECHNOLOGY’s Automatic Gen-

set Controller, the MEC320. The document mainly includes general product information,

display readings, push-button and LED functions, alarm handling descriptions and

presentation of the log list.

The general purpose is to give the operator important information to be used in the daily

operation of the unit.

Intended users

This Operator’s Manual is mainly intended for the daily user. On the basis of this document,

the operator will be able to carry out simple procedures such as start/stop and control of the

generator set.

Contents/overall structure

The document is divided into chapters, and in order to make the structure simple and easy to

use, each chapter will begin from the top of a new page.

Please make sure to read this handbook before working with the MEC320

controller and the gen-set to be controlled. Failure to do this could result in

damage to the equipment or human injury.

2. Warnings and legal information

Legal information and responsibility

THOMSON TECHNOLOGY takes no responsibility for installation or operation of the

generator set. If there is any doubt about how to install or operate the generator set

controlled by the unit, the company responsible for the installation or the operation of the set

must be contacted.

Electrostatic discharge awareness

Sufficient care must be taken to protect the terminals against static discharges during the

installation. Once the unit is installed and connected, these precautions are no longer

necessary.

Safety issues

Installing the unit implies work with dangerous currents and voltages. Therefore, the

installation should only be carried out by authorised personnel who understand the risks

involved in working with live electrical equipment.

Definitions

Throughout this document a number of notes and warnings will be presented. To ensure that

these are noticed, they will be highlighted in order to separate them from the general text.

Notes

Warning

The notes provide general information which will be helpful for the reader to

bear in mind.

The warnings indicate a potentially dangerous situation which could result in

death, personal injury or damaged equipment, if certain guidelines are not

followed.

Be aware of the hazardous live currents and voltages. Do not touch any AC

measurement inputs as this could lead to injury or death.

The units are not to be opened by unauthorised personnel. If opened anyway, the warranty will

be lost.

4. Display and menu structure

LCD display

The display is a backlit LCD text display containing 4 lines with 20 characters in each line.

There is no control of the display light intensity (no dimmer). Basically, all measured and

calculated values can be read in the display. These may be selected via the PC utility

software (TSP300).

Menu structure

The display includes two menu systems which can be used without password entry:

View menu system

This is the commonly used menu system. 15 windows are configurable and can be

entered by using the arrow push-buttons.

Setup menu system (not commonly used by the operator)

This menu system is used for setting up the unit, and if the operator needs detailed

information that is not available in the view menu system.

Changing of parameter settings is password protected.

Entry window

When the unit is powered up, an entry window appears. The entry window is the turning point in the menu structure

and as such the gateway to the other menus. It can always be reached by pushing the EXIT push-button 3 times.

The event and alarm list will appear at power up if an alarm is present.

For selection of values, see the Designer’s Reference Handbook.
