The BC300 is a burner sequencer for industrial burners on thermal process plants. It is designed for use on burners of all sizes in intermittent and continuous operation. The control output can be single stage or two stage, with pneumatic modulation or in cycle operation. The flame can be monitored either with ionisation in single electrode or twin electrode operation, UV tube or F152 with FFS07 or FFS08 optical sensors. The BC300 is also suitable for applications with process temperatures higher than 750 °C. The UI300 user interface can be used to monitor the status of the burner at distance and in low light levels. Intuitive graphics and symbols are used to make the UI300 language neutral and easy to understand. Changes to the settings can be modified on-site with the LSB Remote Software. For error diagnostics, the last 10 faults are saved to the device. A comprehensive list of approvals ensures that the BC300 is suitable for worldwide use.
