The burner control units BCU 480 control, ignite and
monitor gas burners for intermittent or continuous op-
eration. As a result of their fully electronic design, they
react quickly to various process requirements and are
therefore suitable for frequent cycling operation.
They can be used for industrial burners of unlimited
capacity which are ignited by pilot burners. Pilot and
main burners may be modulating or stage-controlled.
The BCU 480 monitors pilot and main burners inde-
pendently. The pilot burner can burn permanently or be
switched off. 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 relate to the burner, for example it ensures that
the burner always ignites in a safe condition when it is
restarted.
The air valve control assists the furnace control for cool-
ing, 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 commission-
ing 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 op-
tical interface.
The BCU unites
the function-
ally interrelated
components of
automatic burner
control unit, igni-
tion transformer,
Manual/Automatic
mode and display
of operating and
fault statuses in
a compact metal
housing.
