Application
▼
The BCU unites
the functionally
interrelated components of automatic burner control unit, ignition
transformer, Manual/Automatic
mode and display
of operating and
fault statuses in
a compact metal
housing.
1 Application
The burner control units BCU 460 and BCU 465 control,
ignite and monitor 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.
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 relate to the burner, for example it ensures that the burner
The optional air valve control on the BCU..L assists the
furnace control for cooling, purging and capacity control 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.

side
The service personnel is supported by a convenient vis-
ualization system of the input and output signals and
the error history.
The new power management scheme reduces installa-
tion and wiring costs. The power for the valves and ignition transformer is supplied via the power supply of the
BCU, protected by a replaceable fine-wire fuse.
The conventional wide-spread systems used in indus-
trial furnace and kiln construction require bridging of
large distances for signal processing. The optionally
available BCU..B1 for connection to the PROFIBUS DP
fieldbus is equipped for this purpose.
As a standardized fieldbus system, the PROFIBUS DP
considerably reduces development, installation and
commissioning costs compared to conventional wiring.
The use of a standard bus system offers massive ben-
efits compared to manufacturer-specific bespoke solutions. Time-tested hardware components, standardized
connection methods and a series of tools of bus diagnostics and optimization are available on the market
from a whole range of manufacturers. The widespread
use of the system ensures that the planning and service personnel are very familiar with how the system operates and how to handle it and can therefore operate
the system efficiently.

BCU 4 60.. B1 for PROFIBU S DP
The bus system transfers the con-
trol signals for starting, resetting
and for controlling the air valve from
the control system (PLC) to the
BCU..B1. In the opposite direction
it sends operating status, the level
of the flame signal and the current
program status.
Control signals that are relevant for
safety, such as the safety interlocks
and digital input, are transferred
independently of the bus communication by separate cables.
