valve (mark 1) in the pipe.

* DE Note

In compliance with the reference layout

applicable to boiler rooms, sites with gas

furnaces must be fitted with a thermal

gas shut-off valve (1).

Description of functions

When first powering up, after a power

cut or a lockout, after the gas supply has

been cut or after a shutdown for 24

hours, a gas valve sealing test is

performed before the burner is started,

with the fan motor in operation. A pre-

ventilation time of 24 seconds begins

after the sealing test.

During the pre-ventilation time

- the air pressure is monitored

- a check is made for the presence of

any abnormal flame signals.

At the end of the pre-ventilation time

- the ignition is switched on

- the main and safety solenoid valves

are opened

- burner start-up

Monitoring

The flame is monitored by an IRD cell

(with PED option: UV cell).

Safety functions

- If no flame is produced when the

burner is started (gas release), the

burner is switched off at the end of the

safety time which lasts no more than

3 seconds and the gas valve closes.

- If the flame is lost during operation,

the gas supply is cut within a second.

A new start-up sequence is activated.

If the burner starts, the operating cycle

starts running. Otherwise a lockout

occurs.

- If there is an air failure during pre-

ventilation or operation, a lockout

occurs.

- If there is a gas failure, the burner

either stops or will not start. As soon

as sufficient gas pressure is available

again, the burner restarts.

During the regulator shutdown

- The control thermostat interrupts the

heating request

- The gas valves close

- The flame goes out

- The blower motor stops

- The burner is ready for operation

Manual locking and unlocking

Using the reset button , the control

and safety unit can be locked manually

(interlocked) or unlocked, provided the

unit is connected to the mains power

supply. This function must not be

confused with automatic locking and

fault acknowledgement in case of an

error.

Before installing or removing the unit or

any operation in the connection area,

switch off the supply to the device, check

for the absence of voltage and prevent

any reactivation. Otherwise there is a

risk of electric shock. The control and

safety unit must not be opened or

repaired.

The control and safety unit BT 3xx

controls and monitors the forced draught

gas burner. The microprocessor-

controlled program sequence ensures

the maximum consistency of the cycle

times involved, regardless of

fluctuations in the mains voltage or

ambient temperature. The control and

safety unit is designed to detect power

failures. Depending on the parameter

assignment, the unit either switches to

malfunction mode or goes into the

standby position if the power supply falls

below the mains voltage. In the standby

position, there is an automatic restart as

soon as the set threshold value is

exceeded by 105%.

controlling the air flap, gas flap, fuel oil

quantity regulation and frequency

converter (optional) in one electronic

circuit.

The electronic circuit controls the

opening of the gas flap and fuel oil flow

regulation proportional to the air flap

along a curve based on 10 setting points

During start up, the setting points are

defined based on the measurement

values of the combustion gas analysis.

This guarantees optimal combustion

over the burner's entire output

modulation range.

A separate burner ignition load can be

defined with the "Ignition position"

setting point .

The limit values of the control range are

defined by the min. output " " and

max. output " " setting points. In

addition, other optional functions, such

as sealing tests, reventilation or waiting

Function

VGx MV/TC burner

Speed control – VSM100 module

Module description

The VSM100 allows the BurnerTronic to control the speed of the

fan motors. The BurnerTronic treats the VSM100 as an additional

compound channel. This allows you to freely define the speed

over the entire load range. The VSM100 is connected to the

BurnerTronic via LSB. The VSM100 delivers the speed setpoint

to the motor driver (frequency converter or the like) as a 0/4–

20mA or 0–10V signal. The VSM100 records the actual speed

and sends it back to the BurnerTronic for monitoring purposes.

Either Namur sensors or 3-lead sensors with a switch output can

be used to record the speed. Feedback via a 0/4 – 20mA current

loop is also possible.

Note: it is only possible to use the VSM100 module in connection

with the LCM100 module.

Note: burners which are equipped with the VSM100 module in

the factory are preset so that the module can be used. Usually,

module settings or configuration of the BurnerTronic are not

required.

Modifications are the responsibility of the operator if a

configuration is selected which deviates in a circuit

diagram of the factory settings. The operator must

ensure that his settings are correct in that it is safe to

operate the burner. Modifications may only be carried

out by qualified trained personnel.

Incorrect setting of the DIP switches can lead to

malfunctions. Before commissioning, the setting

(DIP switch) of the LCM100 module must be checked

according to the circuit diagram. If the DFM300 is

the last device in the CAN bus chain, switch number

1 must be set to 1 (ON). The settings according to the

circuit diagram must be adhered to.

You can configure the BT3xx for the VSM100 module using the

PC software. The settings are made using parameters 403 to

406. Information on the individual parameters can be found in the

parameter list 4200 1018 1501.

During operation with the

frequency converter, the fan

motor starts automatically as

soon as the access code for

menu 1 is confirmed. This is

necessary to obtain feedback

value for the frequency converter

channel.

Compared to operation without

the frequency converter, an

additional channel must be

configured when making settings

in menu 1.

The channel for the frequency

converter can be set and

modified as described for the fuel

and air flap channels in the

chapter “Menu 1: Setting the

servomotors”.

In the factory, the burner is

configured so that the motor

frequency can be set in the

25 – 50Hz range. The value

shown in the bottom right-hand

corner of the displays the

feedback value. It basically

corresponds with the setpoint.

Small deviations from the

setpoint are possible.

If the VSM100 module is used,

the values for the frequency

converter channel are

additionally displayed in menu 2.

Max. gas pressure switch

The gas pressure switch is used to

control gas pressure. The pressure

switch is installed here in order to

monitor pressure increase (maximum

value recommended for installations

implemented according to standard

TRD 604).

The setpoint (switching point) is set on a

rotary scale.

Test burner

Depending on the country-specific

requirements, when installing steam

boilers it may be necessary to fit a test

burner to the gas train (e.g. in line with

the Pressure Equipment directive TRD

412). This is used to vent the gas control

system.

The gas supply is switched on by

pressing the button (1). The flow of gas

brings in the required amount of

combustion air via the hole in the burner

tube (3). The gas/air mixture is routed

towards the burner head (4) and ignited

manually at its opening. Gas is supplied

for as long as the button is pressed and

cut off when it is released.

Technical data:

• Type of gas:

gases in accordance with DVGW

worksheet G 260/1, gas families 1, 2, 3

• Ambient temp.: -15°C to +70°C

• Installation position: vertical, facing

upwards

• Operating pressure to: 500 mbar

Checking the burner head

• Check that the setting of the ignition

electrode corresponds with the

diagrams.

Installation

Checking the burner head for natural gas/propane gas

Burner head setting

The burner head comprises 2 types of

gas diffusers. It is possible to adjust the

amount of gas distributed between the

diffusers marked F and those marked R.

The setting is carried out according to

the rotation of the graduated disc:

(Setting field: 30° in direction R or

direction F)

• Loosen the locking screw S (2.5 mm

Allen key)

• Adjust the graduated disc using a

screwdriver.

• Retighten the locking screw.

This setting has an effect on CO

emissions.

Checks before commissioning

The following must be checked before

initial commissioning:

• That the burner is assembled in

accordance with the instructions given

here.

• That the burner is pre-set in

accordance with the values in the

adjustment table.

• Setting the combustion components.

• The heat generator must be ready for

operation, and the operating

regulations for the heat generator

must be observed.

• All electrical connections must be

correct.

• The heat generator and heating

system must be filled with water and

the circulating pumps must be in

operation.

• The temperature regulator, pressure

regulator, low water detectors and any

other safety or limiting devices that

might be fitted must be connected and

operational.

• The exhaust gas duct must be

unobstructed and the secondary air

system, if available, must be

operational.

• An adequate supply of fresh air must

be guaranteed.

• The heating request must be

• Sufficient gas pressure must be

available.

• The fuel supply lines must be

assembled correctly, checked for

leaks and bled.

• A standard-compliant measuring point

must be available, the exhaust gas

duct up to the measuring point must

be free of leaks to prevent anomalies

in the measurement results.

General regulations applying to the

gas connection

• The gas train must only be connected

to the gas mains by a recognised

specialist.

• The cross-section of the gas line

should be of a size designed to

guarantee that the gas flow pressure

does not drop below the specified

level.

• A manual shut-off valve (not supplied)

must be fitted upstream of the gas

train.

• In Germany, a thermally triggered

shut-off valve (to be installed by the

customer side) must be fitted as

specified by the draft combustion

ordinance.

It is the responsibility of the fitter or his

representative to obtain approval for the

system at the same time as the burner is

commissioned. Only the fitter or his

representative can guarantee that the

system meets applicable standards and

regulations. The fitter should be in

possession of the corresponding official

permit, and should carry out the

corresponding sealing tests and purge

the system of air.

All electrical installation and

connection work must only be carried

out by a suitably qualified service

engineer. N.B.: The applicable

guidelines and directives must be

observed, as well as the electrical

circuit diagram supplied with the

burner.

Electrical connection

• Check to ensure that the power supply

is as specified (230V, 50 Hz single-

phase current with neutral and earth).

It must be possible to disconnect the

burner from the mains using an

omnipolar shutdown device complying

with the standards in force.

A device to protect against short circuits

must also be fitted upstream of the

burner's electrical power supply.

The connection cables for the burner

motor, the control voltage and the gas

train are fixed and routed through cable

grommets 1 and 2. They must be

connected to the terminal in accordance

with the electrical circuit diagram.

To this end, the following conductor

cross-sections must be observed:

Burner motor connection

The burner is supplied for a mains

supply voltage of 400V-50Hz, three-

phase current with a neutral wire and

Adjusting the IRD cell

• Burner operating at minimum power.

• Turn the potentiometer A of the cell until

the LED 1 goes out.

• Increase the potentiometer setting by 2

graduations.

Checking the operation of the IRD cell

The flame monitoring equipment must be

checked to ensure that it is fully functional

as part of initial commissioning and also

after servicing or if the system has been

out of operation for any significant period

of time.

- Starting attempt with flame detector

unlit: the control and safety unit must

switch to malfunction at the end of the

safety time.

- Start-up with the flame detector lit: the

control and safety unit must switch to

malfunction after 10 seconds of pre-

ventilation.

- Normal start-up; if the burner is

operational, the flame detector should

be unlit: after restarting and at the end of

the safety time, the control and safety

unit must switch to malfunction.
