Burner Controller Model AUR255

Burner controller is a combustion safety con troller specifically designed for batch operation (for systems that start and stop at least once in a 24-hour period).
It automatically and safely ignites gas and oil burners using the correct ignition sequence. This device is to be used with the AUD100/110/120 advanced ultraviolet flame detector or with a flame rod.
The front of the unit provides a 7-segment LED display to show the flame voltage and the current sequence stage. Also from the front panel users can access a communication function that is convenient for maintenance and trouble shooting 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 easily view alarm details.
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 infor mation, which is useful for troubleshooting and preventive maintenance.

• The combustion sequence, alarm codes and flame voltage are shown on the 7-segment display.
• LED indicators show whether there is a flame signal and indicate lockout.
• Self-diagnosis of the internal control relay circuit
• If lockout occurs due to ignition failure or unexpected flame failure, the controller does not restart without a manual reset.
• The design complies with JIS C 9730-2-5 and JIS C 9730-1.
• Equipped with host communications (RS-485) to enable remote monitoring.
• DIN rail mounting and a sub-base structure are provided for easy installation and replacement.
• Equipped with a trial logger that records input/output and flame voltage for a fixed period of time from the start of ignition at 100 ms intervals.
• Flame level, which is more responsive than flame voltage as an index for the flame, is provided.
• Indexes of burner health, such as ignition time, are also provided.
