1. About this document
General purpose
This document is the Operator’s Manual for THOMSON TECHNOLOGY’s generator controller
MEC 310. The document includes information about push-buttons, LEDs, display readings, icon list
and basic operational theory.
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 day-to-day procedures.
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 manual 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
Legal information and responsibility
THOMSON TECHNOLOGY takes no responsibility for installation or operation of the engine/generator
set. If there is any uncertainty regarding how to install or operate the engine controlled by the MEC
310, the company responsible for the installation or the operation of the engine/generator set should
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 MEC 310 controller implies work with dangerous currents and voltages. Therefore,
authorized personnel, who understand the risks involved in working with live electrical equipment,
should only undertake the installation.
Factory settings
The unit is delivered with certain factory settings. Given the fact that these settings are based on
generic values, they are not necessarily the correct settings for matching the individual engine.
Therefore precautions must be taken to ensure the suitability of the settings before running the
engine. In some cases protection settings may be disabled in an effort to allow the commissioning
agent ease of initial startup. As such all alarm/shutdown protection settings must be reviewed to
ensure the engine generator set is adequately protected against catastrophic failure.
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
Warnings
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 controllers are not to be opened by unauthorized personnel.
If opened / warranty seals broken, the warranty will be void.

RUN: Permits local engine start and run. Mode Selection must be in MAN to enable this push-
button.
OFF: Stops the engine instantaneously. If the unit is in AUTO mode, the mode will change to
MAN and the engine will immediately stop.
Note: For Shutdown fault clearing the OFF button must 1st be depressed before pressing
the ENTER button. If the condition is still present the shutdown is acknowledged and will
self–clear when the field device or programming logic permits a return to the none-fail
state.
AUTO: AUTO running mode selector.
MAN: Manual Operation Mode selector. Requires RUN Push-button be depressed to initiate
Start/Run Sequence
TEST: Initiates the test sequence selected for the push-button. Test type only programmable
using TPS300 utility software.
LAMP TEST: Lamp test. One push will illuminate all LEDs for 3 seconds.

AMF Push-button/LED Terms & Functions
GCB = Generator Circuit Breaker
UCB = Utility Circuit Breaker
GCB Trip: Generator or automatic transfer switch breaker trip/open push-button. This push-button
is always active when the Manual Operation Mode is selected.
GCB Close: Generator or automatic transfer switch breaker close push-button. This push-button is
only active if the generator is running, its voltage and frequency are within acceptable
limits for the set delay time as defined in programming and the USB Close has been
removed (press UCB Trip to remove GCB close inhibit condition).
UCB Trip: Utility or automatic transfer switch breaker trip/open push-button. This push-button is
always active when the Manual Operation Mode is selected.
UCB Close: Utility or automatic transfer switch breaker close push-button. This push-button is
always active when the Manual Operation Mode is selected. GCB close must be
removed to permit operation.
Changing the operating mode from Manual to Auto will not cause opertional errors. Making
this change will only revert automatic breaker and generator control to the MEC 310. Mode
changes can be made at anytime, however if changing from Automatic to Manual all
operational sequences must be carried out manually. Automatic generator starting and
transferring of essential loads will not occur.
AMF LED Functions
GCB LED: Green LED illuminates when generator circuit breaker is closed.
UCB LED: Green LED illuminates when utility circuit breaker is closed.
Utility Supply Status LED: Provides at a glance health status of the utility supply, these are:
Flashing Red LED = Utility out of limits delay, inhibit engine start.
Solid Red LED = Utility out of limits delay complete, engine start sequence and
transfer blocks removed.
Flashing Green LED = Utility healthy and in Transfer Return Delay.
Solid Green LED = Utility healthy and transfer to generator initiated or complete
