Functional Description
BT300 combines the benefits of an electronic fuel/air ratio control system with up to three mo-
torised actuator elements and optional modules like an analogue output for speed control of
the combustion air fan with an electronic burner control unit. The leakage test, flame monitor-
ing system, power control unit and (optional) CO/O
2
controller for control and optimisation of
an oil or gas-fired forced-draught burner are all integrated.
BT300 is suitable for virtually all combustion plants. Safety interlock chains, monitors (e.g. gas
and air pressure) and sensors are wired directly to the BT300. This greatly reduces the cost
of additional relays and wiring. The BT300 is designed to be attached to the burner. The short
wiring paths also save money. As a result, BT300 is particularly suitable as standard equip-
ment for mono-block burners.
The compact design of BT300 burner control system also has its advantages during commis-
sioning. Standardisation of wiring and operator interface minimises sources of errors right from
the start. Moreover, intelligent display information is making search for errors much easier.
The BT300 is available in six designs:
•
BT320
2 Motorised control outputs
1 Continuous output 0 ... 10 V, 0/4 ... 20 mA for speed control of the
combustion air fan using VSM100 (optional)
Up to version 3.8.0.0 intermittent operation, from serial numbers
22xxxxxx and version 3.9.0.0, the BT320 is also approved for continuous
operation in combination with flame sensors capable of running
continuously
•
BT330
3 Motorised control outputs
1 Continuous output 0 ... 10 V, 0/4 ... 20 mA for speed control of the
combustion air fan using VSM100 (optional)
Approved for continuous operation only in combination with
flame sensors capable of running continuously
•
BT331
Same range of functions as BT330 but including following certificates:
DIN EN 61508:2002 parts 1-7 for SIL 3
Performance Level PLE according DIN EN ISO 13849-1
•
BT335
3 Motorised control outputs
– Oil-gas dual-fuel operation with limited functions is possible without
DFM300
– Pilot burner is not possible
– External reset is only possible with LCM
– No CPI/POC input
– No connection for QAR2, QAR4, QAR10
– No process status signal possible
– Oil operation is possible only modulating or 2-stage.
– 1 Continuous output 0 ... 10 V, 0/4 ... 20 mA for speed control of the
combustion air fan using VSM100 (optional)
– Approved for continuous operation only in combination with flame sensors
capable of running continuously
•
BT340
3 motorised control outputs
Oil-gas dual-fuel operation via DFM300
1 Continuous output 0 ... 10 V, 0/4 ... 20 mA for speed control of the
combustion air fan using VSM100 (optional)
Approved for continuous operation only in combination with
flame sensors capable of running continuously
