Description

The BCU (burner control unit) 465 enhances the features of BCU 460 by adding Proof of Closure switch monitoring and purge timing. It is for directly ignited burners of unlimited capacity (air valve control optional). The unit ignites and monitors gas burners for intermittent or continuous operation. As a result of their fully electronic design they react quickly to various process requirements and are therefore suitable for frequent cycling operation.

It can be used for directly ignited industrial burners of unlimited capacity. The burners can be modulating or step-by-step controlled. The BCU is installed near the burner to be monitored.

On industrial furnaces, the BCU relieves the load on the furnace control by taking over tasks that only relate to the burner, for example it ensures that the burner always ignites in a safe condition after it has been restarted.

The optional air valve control on the BCU..L assists the furnace control for cooling, purging, and capacity control tasks.

The program status, the unit parameters, and the level of the flame signal can be read directly from the unit. The burner can be controlled manually for commissioning and diagnostic purposes. If the local requirements on the burner control unit change, the software BCSoft can be adjusted to the unit parameters of the application by using the optical interface.

Users can see input and output signals and the error history.
