The next-generation burner control unit BCU460/465
unites the components of automatic burner control
unit, ignition transformer, Manual/Automatic mode,
display of operating and fault statuses and a user inter-
face (HMI) in a compact metal housing. It replaces the
previous product line with the same name. It is suitable
for almost every conceivable multiple burner applica-
tion in the metal, ceramics, food and automotive indus-
tries.
It can be used for directly ignited industrial burners of
unlimited capacity. The burners may be modulating-
controlled or stage-controlled. Installation in the imme-
diate vicinity of the burner being monitored simplifies
system integration.
On industrial furnaces, it reduces the load on the cen-
tral furnace control by taking over tasks that relate to
the burner, for example it ensures that the burner ig-
nites in a safe condition when it is restarted.
The air control on the BCU..F1 or F3 assists the furnace
control for cooling, purging and capacity control tasks.
The burner control unit has an interface via which an air
valve or actuator can be controlled for staged or modu-
lating burner capacity control.
The program status, device parameters, error codes,
statistics and level of the flame signal can be read eas-
ily and conveniently on the four-digit device display.
The burner can be controlled manually for commission-
ing, maintenance and diagnostic purposes.
Energy management using phase reduces the instal-
lation and cabling costs. The valves and ignition trans-
former are powered by phaseL1/the voltage supply for
the BCU instead of the safety interlocks.
The monitored outputs for the actuator and valve are
housed in the plug-in power module LM400. This can
easily be replaced if necessary.
