Functional DescriptionThe BT300 combines the benefits of an electronic fuel-air ratio control system with up to three motorised 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 monitoring system, power control unit and (optional) CO/O2 controller for control and optimization of an oil or gas-fired forced-draught burner are all integrated. The 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 was designed to be attached to the burner. The short wiring paths also save money.The BT300 is available in five designs:l BT320 - Brenner Management System for Oil- or Gas burner´ for intermittent Operation - Valve Proving System - Fuel – Air Ratio Control for 2 Actuatorsl BT330 (BT331 with SIL3) -Brenner Management System for Oil- or Gas burner for continuous Operation (Ionization or Flame safeguard) - Valve Proving System - Fuel – Air Ratio Control for up to 3 Actuators Optional Variable Speed Control for the Fan Motorl BT340 (BT341 with SIL3) -Brenner Management System for Oil-, Gas- or Dual Fuel burners for continuous Operation (Ionization or Flame safeguard) - Valve Proving System - Fuel – Air Ratio Control for up to 3 Actuators and Optional Variable Speed Control for the Fan Motor
