Burner Controller Model: AUR255_1F

The model AUR255_1F burner controller with NFPA timing design requires little installation space and can be used for batch operations for systems that start and stop at least once in a 24-hour period. It follows the correct ignition sequence to automatically and safely ignite gas burners and oil burners. This device is compatible with model AUD100/110/120 advanced ultraviolet flame detector or a flame rod.

Various kinds of data are recorded in the AUR255, including flame voltage, ignition delay time, combustion counts, and combustion sequence stage.

The front 7-segment LED display shows the flame voltage and the current sequence stage. From the front panel, users can access a communication function that is convenient for maintenance and troubleshooting and an event function. The 7-segment LED display shows not only the normal operating sequence and flame voltage but also the sequence code and alarm code alternately in the event of an alarm, allowing users to view alarm details easily. The communication function can be used to read out basic information such as the status of input/output and the operating history, alarm history, and other internal information, which is useful for troubleshooting and preventive maintenance.

The Ignition trial time is 13.5s for the NFPA approved applications but can be selected also from 4.5 s, 9.0 s. To ensure timely replacement of the ultraviolet flame detector, the event function outputs a reminder after 25,000 hours of combustion use.

Wires connect to the sub-base (BC-R05A100, sold separately), making the unit easy to install/remove. The flame monitor output and alarm output contacts are available as semiconductor output and relay output, respectively. External reset input provides the ability to reset from a control panel.
