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

6. Functional descriptions

This chapter includes functional descriptions for the unit’s standard functions. Screen dumps and
flow charts are used in order to simplify the information.

Alarm function

The unit will detect and display individual alarms that are enabled. Furthermore, it is possible to
activate relays for alarm purposes. The alarms can be configured to any of the available relay
outputs. Each alarm function has two output settings, namely output A and output B.

Alarms can be acknowledged in one of two ways: Either the binary input “alarm ack.” (selectable to
be one of the binary inputs 10, 11, 12, 13, 14 and 15) is used, if this is configured for alarm
acknowledge, or the select button on the display is used:

The alarm acknowledge input acknowledges all present alarms, and the alarm LED will

•

change from flashing to steady light.

The display can be used in the alarm information window. The alarm information window

•

displays one alarm at a time and the alarm state whether the alarm is acknowledged or not.
If it is unacknowledged, then press to acknowledge it. Use the ▲ and ▼push-buttons to
scroll in the alarm list.

Shortcut to Alarm list: press and hold

•

The alarm LED will be flashing, if unacknowledged alarms are present. The alarm relay will
deactivate, when the alarm situation is reset and the alarm is acknowledged.

Timer function

The delay settings are all of the definite time type, i.e. a set point and time is selected.

If the function is e.g. overspeed, the timer will be activated, if the set point is exceeded. If the RPM
value goes below the set point value before the timer runs out, then the timer will be stopped and
reset.

Measured

Set point

value

When the timer runs out and the alarm is present, the output is activated.

PM075 REV 2 09/08/20 Page 28 THOMSON TECHNOLOGY

MEC 310 GENSET CONTROLLER

Start enable is start control only, i.e. if removed when the engine is running, the

engine keeps on running.

Mains voltage unbalance detection

The formula for mains voltage unbalance is:

(Most deviating line-to-line voltage - average voltage)*100/average voltage (nominal value in %)

Phase sequence error

Prior to closing a breaker the unit checks that the phase sequence is correct, depending on the
chosen phase direction in parameter 2280: “phase rotation”. If it’s incorrect (reversed), an alarm will
be issued and the breaker in question (generator or option A mains breaker) will not be closed and
the breaker’s LED will flash red.

TPS 300 software input configuration

It is possible to configure the inputs indicated in the table. The unit has a number of passive binary
inputs (input terminals 10-15).

6. GB Pos on

When this input is activated, the MEC 310 sees the generator breaker as closed. If the GB on
and the off feedback are on or off simultaneously, a GB position failure is displayed.

7. GB Pos off

When this input is activated, the MEC 310 sees the generator breaker as open. If the GB on and
the off feedback are on or off simultaneously, a GB position failure is displayed.

8. MB Pos on

When this input is activated, the MEC 310 sees the mains breaker as open. If the MB on and the
off feedback are on or off simultaneously, an MB position failure is displayed.

9. MB Pos off

When this input is activated, the MEC 310 sees the mains breaker as open. If the MB on and the
off feedback are on or off simultaneously, an MB position failure is displayed.

10. Access lock

Activating the access lock input deactivates the control push-buttons on the display. It will only
be possible to view measurements, alarms and the log.

11. Mode shift

Selection between manual and auto running. The mode is changed every time the input is
activated (pulse input).

12. Fire pump (shutdown override)

Deactivates all protection functions except overspeed and emergency stop protection.

13. Remote start/stop input

Activating this input will start the gen-set. Deactivating it will stop the gen-set after cool down
(auto mode only).

14. D+ (digital running feedback)

This input is used as a running indication of the engine. When the input is activated, the start
relay is deactivated. Input for running feedback from charge generator +D terminal. (Runs when
charger U > battery voltage).

15. Digital inputs 1…6

These inputs are configurable as alarm inputs.

16. Idle speed

Activating the idle speed input holds the engine at idle speed for as long as it is set.

17. Inhibit EI alarms

Output function description

1. Run coil

The relay configured to Run coil will be closed the entire time the engine is supposed to run.

2. Stop coil

This relay will close to stop the engine, and when no running feedback is present it will stay
closed in the ext. stop time (parameter 6212).

3. Prepare

This function will close the relay as the first thing in the start sequence. The relay will be closed
for the time programmed in parameter 6181. This function is used for preheating the engine or
for prelubrication.

4. Starter

The relay configured to Starter will be closed for the time selected in parameter 6184 in the start
sequence of the MEC 310.

5. Engine run indication

If a relay is configured to this function, this relay will close when a running feedback is detected.
The relay will open again when the engine stops.

6. Idle speed output

This relay will close to give the engine governor the idle command (Low speed).

7.

Horn

The horn relay is a common alarm output. This means that every time an alarm state appears
the horn relay will close for the time configured in the parameter 6130 Alarm horn regardless of

fail class. If 6130 is set to 0 seconds, it will be on until the reset horn push-button is activated or
the alarm(s) has (have) been acknowledged.

8. Alarm/limit

When this setting for the relay is selected, the relay can be used in the alarm parameters in the
setting Output A and Output B. This means that with factory settings, the relay 2 can be used in
the parameters as an alarm relay. If the relay is preferred to be a Limit relay, this selection must
be done in the parameter list parameter 5000 to 5060.

9. Fuel pump

Output must be configured to use fuel pump settings.

10. Engine heater

The relay configured to Engine heater will close when the temperature is below the set point in
parameter 6320 and open again when the temperature is above the set point in parameter 6330.
For more information, see the description of the function.

11. Stop coil (not acc. in start seq.)

The relay configured to this function will do the same as the normal stop coil with one exception:
It will not close between the start attempts.

After configuration of the input parameter, it is possible to assign an output. Use the dialogue box
below for configuration of the output relay.

Remember to save and write the settings to the MEC 310 before closing the dialogue box.

The service timer alarm must be reset in the parameter list of the MEC 310 or via

Service timers

The controller can monitor two different maintenance intervals:

Service timer 1
Service timer 2

The service timers both have the possibility of a setting for days (total elapsed time) and hours
(running hours). The day setting counts whenever there is aux. supply on the MEC 310, and the
hours count when a running feedback is present. It is possible to set the service timers to count up
or count down.

The service timer alarm activates whenever the amount of days or the amount of running hours has
expired. If the service timer is set to count down the display will shown 0 days or 0 hours; if the
service timer is set to count up the display will show the amount of days or hours programmed in
the parameter.

When the service timer alarm appears it can be acknowledged but the alarm will not become
inactive before the service timer has been reset. This can be done from the display or via the TPS
300 software. Whenever the service timer is reset, the timer will start counting from the initial value.

way we are using the same order as in the TPS 300 software.

VDO sensors are noise sensitive; therefore we recommend using 2 wire sensors.

There are three VDO inputs in the unit. The inputs have different functions due to the fact that the
hardware design is able to cover several VDO types.

All VDO inputs have a general accuracy of 2%.

VDO input 1: Fuel level sensor - max. 180 Ohm
VDO input 2: Oil pressure - max. 240 Ohm
VDO input 3: Cooling water temperature - max. 2500 Ohm

Configuration

The 8 curve settings for the configurable VDO inputs cannot be changed in the display, but

only

in

the TPS 300 software.

Binary inputs with cable supervision

The binary inputs are based on the VDO inputs, i.e. if a VDO input is selected, the binary input
cannot be chosen, and vice versa. When selected as multi-functional inputs, the 3 VDO inputs can
be changed to binary inputs with cable supervision. The cable supervision is selectable (ON/OFF)
and based on the VDO inputs using a 100 Ohm resistor across the monitored switch. The resulting
function is:

R < 20 Ohm = Switch closed
30 < R < 140 Ohm = Switch open, cable OK
150 Ohm < R = Wire break

The setting of the alarm input is carried out in the same way as the setting of the standard binary
input. The texts can be changed in translation.

Generator breaker control

Breaker closing

Since the generator is assumed to run alone (single generator island), the breaker will close
immediately when the Hz/V OK status is reached (AUTO), or if the breaker close button is activated
(LOCAL). In LOCAL mode the breaker can be closed by pressing the GB close button on the front
of the MEC 310, when Hz/V is OK.

Relay output control

The generator breaker is assumed to be a contactor, i.e. the relay output is steady ON when the
breaker is closed, and steady OFF when the breaker is open. It is not possible to have 2 pulse
outputs for a motorised breaker (ON and OFF).

Breaker trip control

Any alarm selected to have the fail class

Trip

or

Shutdown

will automatically open the breaker
control relay. If the breaker is closed when the idle speed is activated, a breaker out signal will be
transmitted.

Breaker ON/OFF feedback

As default there is no feedback for breaker ON or OFF. The breaker position LED is paralleled to
the breaker control relay output. It is possible, however, to select a binary input to be breaker ON
feedback and/or an OFF feedback. This is done via an extra selection in the input settings of the
TPS 300 software. This extra input is called

GB Pos on or GB Pos off

These alarms are fixed with the fail class

.

Engine temperature controlled GB closing

This function can be used, if it is recommendable that the engine cooling water temperature must
be above a certain temperature before the engine is loaded. In the parameter 6360 it is possible to
set the cooling water temperature that must be exceeded, before the generator breaker is closed.

The function is also enabled/disabled in parameter 6360. An engine heating message is displayed,
until the engine cooling water temperature has reached the set point in parameter 6360.

The engine cooling water temperature sensor must be selected to be a VDO sensor to make the
function work. If the option A (AMF logic) is enabled, this function will also work upon a mains
failure.

Cool-down controlled by engine temperature

The engine temperature-controlled cool-down is to ensure that the engine is cooled down below the
set point in parameter 6213 “Cool-down temperature” before the engine is stopped. This is
particularly beneficial if the engine has been running for a short period of time, and therefore has
not achieved normal cooling water temperature, as the cool-down period will be very short or none

PM075 REV 2 09/08/20 Page 64 THOMSON TECHNOLOGY

MEC 310 GENSET CONTROLLER

at all and hereby save fuel. If the engine has been running for a long period it will have reached
normal running temperature, the cool-down period will be the exact time it takes to lower the
temperature to be less than the temperature in set point 6213.

If, for some reason, the engine cannot lower the temperature below the temperature set point in
6230 within the time limit in parameter 6560, the engine will be shut down due to this timer. The
reason for this could be high ambient temperature.

The temperature-controlled cool-down function is selected in parameter 6214.

Test function

The MEC 310 has two test sequences if the option A is enabled. The test sequences can be
initiated in two ways: Either with the test push-button on the front of the MEC 310 or by a digital
input configured to this function.

Simple test function

When the simple test is initiated, the MEC 310 will go through the start sequence and run the
engine for the time set in parameter 7090. In this parameter it is also selected if this sequence
should be started by a digital input and/or the test push-button on the front of the MEC 310. If the
timer is set to 0, the test sequence will be interrupted when the digital input or test push-button is
deactivated. This means that digital input can be used to activate and deactivate the test sequence.
When the timer runs out or the input is deactivated (timer set to 0), the stop sequence including
cooling down will be carried out.

PM075 REV 2 09/08/20 Page 65 THOMSON TECHNOLOGY

The MEC 310 must be in Auto mode in order to initiate the test sequence.

MEC 310 GENSET CONTROLLER

AMF test function (A dependent)

When the AMF test is initiated, the MEC 310 will go through the AMF sequence and run the engine
for the time set in parameter 7040. In this parameter it is also selected if this sequence should be
started by a digital input and/or the test push-button on the front of the MEC 310. If the timer is set
to 0, the test sequence will be interrupted when the digital input or test push-button is deactivated.
This means that digital input can be used to activate and deactivate the test sequence. When the
timer runs out or the input is deactivated (timer set to 0), the mains restore sequence and the stop
sequence including cooling down will be carried out.

M-logic

M-logic functionality is included in the unit and is not an option-dependent function.

M-logic is used to execute different commands at predefined conditions. M-logic is not a PLC but
substitutes one, if only very simple commands are needed.

M-logic is a simple tool based on logic events. One or more input conditions are defined, and at the
activation of those inputs the defined output will occur. A great variety of inputs can be selected,
such as digital inputs, alarm conditions and running conditions. A variety of the outputs can also be
selected, such as relay outputs, change of gen-set modes, alarm LEDs and change of running
modes.

The M-logic is part of the TPS 300 software, and as such it can only b
configured in the TPS 300 software and not via the display.

The main purpose of M-logic is to give the operator/designer more flexible possibilities of operating
the generator control system.

The MEC 310 has a built-in buzzer. The buzzer is configured in M-logic. This means that if the
buzzer is going to be used as a horn annunciator, the input must be set to ‘Horn’ and the output
must be set to ‘Buzzer’. The buzzer will act concurrently to the horn output timer. If the delay timer
in M-logic is used, the buzzer will be active after this time delay. See example below.

GSM communication

GSM communication can be used for 2 purposes:

1. Sending SMS alarm messages to up to 5 different mobile phones. The messages will be sent

in clear text, representing the alarm in question (e.g. “Overspeed”) and an ID. The ID
represents the total numbers of sent SMS.

2. Communicate with the MEC 310 TSP 300 software.

Connection:

MEC 310

The connection is based on an RS232 connection to a GSM modem via the service port on the
MEC 310. Since the connection on the MEC 310 is a TTL communication, the SSP interface box is
needed to convert the signals to RS232. The SSP connects via a cable with SUB-D 9-pin female
connector on the modem side.

We recommend using Siemens MC35 modem. The easiest way to get the modem is to purchase it
through a local dealer. The SIM card needed comes from your local mobile net provider. The
easiest way to set the PIN code in the modem itself is to mount the SIM card in a mobile phone and
change the PIN code there. The SIM card will remember the PIN code when it is installed in the
modem.

lock-up of the modem. The easiest way to do this is to use a 24 hour watch.

Should an alarm occur during the interruption, the multi-line unit will re-transmit it when the modem
starts again, so no messages are lost.

The setting of communication protocol ASCII or RTU can be set in the display.

In the above example the modem is selected automatically by the TPS 300
software (internal modem in the PC).

When you want to use modem dial-up, the TPS 300 software must also be set to run ASCII 7 bits

If the communication fails, the MEC 310 unit will operate according to the received data. If e.g. only
half of the parameter file has been downloaded when the communication is interrupted, the settings
are going to be a mix.

6290 Idle mode

6290 Idle mode can be selected in 2 ways:

1. Configurable binary input

2. Timer setting

If a binary input for idle mode is used, activating this will hold the engine in idle mode for as long as
the input is activated. This works for both manual and auto mode. Any time the idle mode is
activated, the generator breaker will be opened.

If a binary input is not used, a timer function can be set to hold the engine in idle upon start until the
timer runs out. This function can be selected to be:

• Off (no idling of engine upon start)

• Active for:

- both manual and auto: Select MAN/AUTO.

- manual only: Select MAN

- auto only: Select AUTO

In both cases a relay must be selected to Idle in the output list. When idle mode is selected, a delay
where the engine is running at low RPM is given. The delay is controlled by the MEC 310, and a
relay output will activate the idle control on the engine.

Engine heater

The external heater function can be used to turn on an external heat source, when the engine
cooling water temperature gets below the limit in parameter 6320. When the engine cooling water
temperature reaches the temperature set point in parameter 6330, the heater is turned off again.

A relay must be selected in the output list to turn this external heat source on/off. The relay will
close to turn the heater on or open to turn it off.

This function will only work, if the engine cooling water temperature sensor is selected to be a VDO
sensor.

5. Parameter list

This chapter includes a complete standard parameter list for setup. Therefore, this chapter is to be
used for reference, when information about specific parameters is needed.

Parameter groups

In the parameter overview, the parameters are divided into three parameter groups. The parameter
groups can be enabled and disabled in the parameters 6950-6970. If a parameter group is enabled,
the parameters will be accessible from the display of the MEC 310. To see the specific parameter,
see in the parameter list. If e.g. a parameter is marked (P2), it is available from the display, if
parameter group 2 is enabled. The default display parameter setting is the parameter setting that
will always be present in the display parameter list. These parameters are marked with a *.

Setup

The setup of parameters is performed via the display or the TPS 300 software. Therefore, the
default settings can be changed to the relevant settings through the TPS 300 software or by means
of the push-buttons on the display.

The settings can be entered through the setup menu. If no entry has taken place before, then the
first display to appear is the password display. Enter the factory setting password to gain access to
the menus.

If no action has been taken after 30 seconds, then the password entry will be deactivated, and a
new password entry is needed. (If entry via the TPS 300 is used, the password is only needed once
per connection).

The factory Customer password is 2000. The factory Service password is 2001.
