3 Brief Description
3 Brief Description
The Burner Control FA1 is suitable for control of burners and combustion systems for gase-
ous, liquid and solid fuels, with permanent operation, also in hot air generators.
Connections for Interbus-S, PROFIBUS DP, CANopen, TCP/IP (Modbus TCP) and Modbus
RTU are available as optional equipment. The connection of other plant components e.g. O2
trim is by the LAMTEC SYSTEM BUS interface to a 9-pole Sub-D connector.
The operation is via optional PC software or programming unit. As display for end user, a cus-
tomer interface is connectable by LAMTEC SYSTEM BUS. The operation by PC software is
described in a separate manual
The FA1 continuously monitors its own functions and those of the connected control elements.
230 V outputs:
– actuation of the gas valves
– actuation of the oil valves
– actuation of the oil pump/rotary atomiser
– actuation of the ignition valve and the ignition transformer
– fan release
– fault message
– OPEN/CLOSE control signals (three-point-step or 4 ... 20 mA) for the mechanical fuel/air
ratio control
External signals to the FA1 are transmitted via floating contacts or chains of contacts.
The following signals can be pre-set:
– 3 separate safety interlock chains
– gas < max
– air pressure monitor
– pre-purge suppression
– minimum gas pressure monitor (for valve leakage test) gas >min
– flame signal
– burner on
– fuel selection
– oil pressure min / atomiser air pressure
– oil pressure max
– ignition position acknowledgement
– internal burner firing rate controller in combination with the control output

4.1 Use of the Operating Unit
With the operating unit you may operate and the program the burner control system.
4.2 Connecting the Burner Control FA1
1. Connect the operating unit to the FA1 by using a 9-pin Cannon connector. To do so, use
the supplied connecting cable, type 663R0430.
Data transmission takes place by the LAMTEC SYSTEM BUS.
2. Alternatively:
Connect the operating unit with the cable of the customer interface. An adapter cable,
type 663R0426, is supplied for this purpose.
Disconnect the 6-pin connector from the customer interface and connect the adapter cable
to the 6-pin connector.

5 Operating Description
5 Operating Description
(see example diagrams in chapter 11.7 Process Sequence Charts)
A signal is first fed to terminal 58 (Burner On) indicating when the burner is to start. The Burner
Control FA1 then interrogates the boiler safety interlock circuit and the air pressure monitor
contact. If it does not detect a proper condition, the text of a corresponding message is indi-
cated and the operating control stops.
If all signals are in proper condition, the fan output is activated and the channel runs to his
bottom stop as a check.
If the channel has reached his bottom stop, it opens for aeration. The valve leakage test runs
in parallel (gas operation only).
In the case of control element the aeration is used to enter and/or test the range limit. After
reaching its top position, the mechanical fuel/air ratio control element remains in the open po-
sition. The FA1 then interrogates the air pressure monitor. If this signal is in proper condtioion,
the parameter set aeration time runs. When this time has expired the channel runs to the pro-
grammed ignition position. Once the channel has reached the ignition position the ignition
transformer is activated on its own for 3 seconds. The oil pump also starts up during oil oper-
ation
Before the valves open the respective fuel safety interlock circuit must be closed.
5.1 Starting without Pilot Burner
The main valves open and together with the ignition transformer remain activated for the du-
ration of the safety time. During this time the flame signal appears.
5.2 Starting with Pilot Burner
The ignition valve and main gas 1 (in gas operation) or the ignition valve alone (in oil operation)
run open. The pilot flame forms and the flame detection detects the flame. The flame detection
sends the signal to the burner control device.
On expiry of the 1st safety time, the ignition transformer switches off. For 3 sec. (stabilisation
time) the pilot burner burns alone. Then main gas 2 or the oil valve opens and remains acti-
vated in parallel with the ignition valve for the duration of the 2nd safety time. The ignition valve
closes again at the end of this period.
3 seconds after ignition, all channels run to the programmed base firing rate point. The FA1
remains in base firing rate position until control release is given.
After control release the FA1 follows the power control unit’s default setting.
A shut off follows the cancelling of the signal of the terminal 58. The main valves close. In gas
operation, first main gas 1 and second main gas 2 closes with a delay of approx. 5 sec., in
order to allow the test line between the solenoid valves to burn out. In the event of a fault shut-
down, both close immediately.
If configured for post-purge, the air channels open again for this period.
Thereafter the FA1 is in the "OFF" mode.

Set the maintenance mode with this parameter. The
maintenance mode sets the pilot burner or the ignition
flame monitor. It enables to do 5 consecutive ignition
attempts without restarting with pre-purge and the leak-

flame stabilisation time. You may not open the main
valves before the reset of this parameter.
After the 5th attempt pre-purge and leakage start auto-
matically.
Note:
A "Total Reset" resets the counter for maintenance
mode automatically i.e. the next cycle is treated as the
first and pre-purge and the leakage test are running.
Therefore, reset faults with a "Partial Reset" wherever
possible (selection switch on "Status", first channel key
2 upwards, then in addition channel key 1 downwards).
Attention: You may not use a partial reset for some
faults.
