1. About this document

General purpose

This document is the M-Logic handbook for Thomson Technology’s MEC 310 Generator

Controller. The document mainly includes a general description, information about programming,

overall configuration and relay configuration.

The general purpose of this handbook is to inform the intended users about programming and

configuration of the M-Logic tool.

Intended users

The handbook is mainly intended for the person responsible for the unit setup. In most cases, this

would be a panel builder designer. Naturally, other users might also find useful information in the

handbook.

Please make sure to read this handbook before working with the MEC 310

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

This chapter includes important information about general legal issues relevant in the handling of

Thomson Technology products. Furthermore, some overall safety precautions will be introduced

and recommended. Finally, the highlighted notes and warnings, which will be used throughout the

document, are presented.

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 authorized personnel who understand the risks involved in working

with live electrical equipment.

Factory settings

The unit is delivered with certain factory settings. Given the fact that these settings are based on

average values, they are not necessarily the correct settings for matching the individual engine.

Thus precautions must be taken to check the settings before running the engine.

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

The notes provide general information which wi

ll be helpful for the reader to

bear in mind.

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 unauthorized personnel. If opened anyway, the

warranty will be lost.

Warnings

The warnings indicate a potentially dangerous situation, which could result

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

followed.

3. General description

This chapter includes overall product information about the unit in general and its place in the

Thomson Technology product range.

Introduction

The M-Logic is a small logic controller incorporated in the MEC 310 controller. Even though it is a

logic controller, it must not be confused with a PLC. The M-Logic can be compared with a PLC

limited in functionality and can only be used for uncomplicated tasks.

The M-Logic can carry out binary control functions only; there are no possibilities for analogue

reading and/or control functions.

The M-Logic can be programmed from the free PC tool called TPS 300 Utility Software (ver. 3).

The TPS 300 software can be downloaded from:

www.thomsontechnology.com

M-Logic setting is done in command lines. There are 40 lines, and each line contains 3 events, 2

operators and one output with a possibility to make a time delay.

If 3 operators are not enough, a number of virtual events can be used to pass the control on to

another line and carry on there. This makes it possible to build larger event based controls.

4. Configuration

Starting

Once TPS 300 has been started, there will be an icon on the lower left-

hand side to activate M-Logic.

Click the icon, and the following screen appears:

PM103 R0 09/08/20 Page 6THOMSON TECHNOLOGY

Read/write

When the M-Logic screen is shown, the M-Logic toolbar appears at the top of the screen. The

toolbar has two buttons which are used to write and read the M-Logic configuration to and from the

unit.

The M-Logic configuration can also be saved/opened to/from a file using the default save/open

buttons.

Read M-Logic settings from the unit

Activating this button will read all M-Logic settings from the unit to TPS 300.

Write M-Logic settings to the unit

Activating this button will write the M-Logic settings from TPS 300 to the unit.

Save/open

Save

Activating this button makes it possible to save the M-Logic configuration to file

(part of the general MEC 310 configuration file “.USW”).

Open

Activating this button makes it possible to open a previously saved logics file.

Basic functions

The M-Logic consists of a number of “lines”, Logic 1, Logic 2 and so on. Each of these lines have

3 event settings, 2 operator settings, an enable tick box and one output setting.

The available functions are:

Events A, B and C

These are used to trigger the logic.

Note that for each event the function “NOT” can be selected

to get an inverted function.

When opening the roll-down window of the events, this

window appears:

Alarms: Use an alarm to activate.

Limits: Same as alarms, only with no time delay.

Events: Events that are not alarms, e.g.

“Engine running”.

Logic: Can be TRUE or FALSE. TRUE means always, FALSE means never.

Inputs: Direct activation of a binary input. The availability of binary inputs is

option dependent.

Modes: Are running modes and plant modes, e.g. “AUTO”.

Relays: Activation when a relay activates. The availability of relay outputs is

option dependent.

Virtual

events: Is a number of internal (virtual) events that can be activated from another logic

line. By using these virtual events, the number of activating (triggering) events

can be expanded from the 3 available in each logic line to, in theory, an

unlimited number of events.

Fail class: The event activates upon activation of any alarm with the chosen fail class,

e.g. “Shutdown”.

Command

timers

1 s pulse: If the activating (triggering) event is required to be a pulse, these can be used.

Power Manage-

ment: Status related to power management, e.g. “Engine 1 running”.
