Application - Honeywell BCU 460 Technical Information

Application

1 Application
The burner control units BCU 460 and BCU 465 control,
ignite and monitor gas burners for intermittent or con-
tinuous operation. As a result of their fully electronic de-
sign, they react quickly to various process requirements
and are therefore suitable for frequent cycling operation.
They can be used for directly ignited industrial burners
of unlimited capacity. The burners may be modulating or
stage-controlled. The BCU is installed near the burner
to be monitored.
On industrial furnaces, the BCU reduces the load on the
central furnace control by taking over tasks that only re-
late to the burner, for example it ensures that the burner
always ignites in a safe condition after it has been re-
started.
BCU 460, BCU 465 · Edition 03.16l
The optional air valve control on the BCU..L assists the
furnace control for cooling, purging and capacity con-
trol tasks.
The BCU 465..L is fitted with air flow monitoring and pre-
and post-ventilation for use on recuperative burners.
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 PC software BCSoft can be adjusted to the
unit parameters of the application by using the optical
interface.
