Burner control unit with plug-in spring force connection termi-
nals
Burner control unit BCU 580 controls, ignites and
monitors gas burners in intermittent or continuous
operation. It can be used for gas burners of unlimited
capacity which are ignited by pilot burners. The burners
may be modulating-controlled or stage-controlled. Its
fast reaction to various process requirements makes
the BCU suitable for frequent cycling operation.
On industrial furnaces, it reduces the load on the
central furnace control by taking over tasks that relate
to the burner, for example it ensures that the burner
ignites in a safe condition when it is restarted.
The air control on the BCU..F1, F2 or F3 assists the
furnace control for cooling, purging and capacity
control tasks.
BCU 580 · Edition 11.15l
The burner control unit has an interface via which
an air valve or actuator (IC 20, IC 40 or RBW) can be
controlled for staged or modulating burner capacity
control.
The program status, the unit parameters and the level
of the flame signal can be read directly from the unit.
The burners or a connected control element can be
activated manually using the integrated Manual mode
for setting and diagnostic purposes.
Thanks to the optionally integrated valve proving sys-
tem, the valves can be checked for leaks by querying
an external gas pressure switch or it can be checked
whether the gas valve on the inlet side is closed.
