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.
The units are not to be opened by unauthorized personnel. If opened anyway, the
warranty will be lost.
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.
measurement inputs as this could lead to injury or death.
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.

3. General product information
This chapter includes overall product information about the unit in general and its place in the
Thomson Technology product range.
Introduction
The concept of the MEC 310 is to offer a simple and effective solution to gen-set builders, who
need a flexible yet cost-competitive protection and control unit for small and medium-sized
generators.
Type of product
The Generator Controller MEC 310 is a microprocessor-based control unit containing all necessary
functions for protection and control of a power generator. Besides the control and protection of the
diesel engine it contains a full 3-phase AC voltage and current measuring circuit. The unit is
equipped with an LCD display presenting all values and alarms.

* If terminal 20 is used for emergency stop, please see wiring diagram on page 15.
** The status relay is the uP watchdog output. This relay is normally energised, and the switch is
closed after power-up. If the uP fails or the power is lost, the relay will de-energize and the
switch will open. If the unit fails to start up at power-up, then the relay switch will remain open.
The binary output functions are configurable via the TPS 300 software and can be configured to

Charger alternator connections
The charger alternator can be connected in 2 different ways:
1) Using the D+ terminal connected to terminal 12

At standstill the battery + is connected to terminal 9 (common), and a current flows to terminal 12
and via the D+ input on the alternator to ground (battery -). When the starter is engaged (cranking),
the battery will supply the D+ through the REX resistor, helping the alternator to excite. When the
alternator starts to produce voltage (excitation OK), the speed of the alternator will be above
running speed, and the voltage on term. 12 will rise to a value higher than the battery voltage and
then interrupt the current flow through REX and activate the running feedback input. Engine is
