Application
Power module LM 400 with connections for valves, actuator
and parameterizable signalling contacts
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 gas valves are closed.
As an option, the BCU can be configured with high tem-
perature operation and an operating mode for low NOx
emissions. In High temperature mode, the BCU can
monitor the flame indirectly using the temperature. The
Low NOx mode leads to a significant reduction in ther-
mal NOx formation in ON/OFF-controlled high-velocity
burners due to its flameless operation.
Using the BCSoft program, the parameters, analysis
and diagnostic information can be read from a BCU via
the optionally available opto-adapter. If necessary, the
device parameters can be adjusted easily using BCSoft.
All valid parameters are saved on an integrated param-
eter chip card. The parameter chip card can be removed
from the old unit and inserted into a new BCU to trans-
fer the parameters, for example when replacing the unit.
The burner control unit is IIoT-compatible using the bus
module BCM 400. The BCU can be networked with a
standardized fieldbus system (PROFIBUS, PROFINET
or EtherNet/IP) using the BCM. Networking in a field-
bus system enables the burner control unit BCU to be
controlled and monitored by an automation system
(e.g. PLC). This also opens up a wide range of process
visualization possibilities.
