Checking the usage
Burner control units BCU 460, 465 and 480 are de-
signed to control, ignite and monitor gas burners in
intermittent or continuous operation. They replace
the local control cabinet. Air and gas flow monitoring
as an option.
The outputs for controlling the burners, e.g. for ac-
tuator and valves, are activated via the replaceable
power module LM 400. All the parameters required
for operation are saved on the integrated parameter
chip card.
BCU 460, BCU 465
For directly ignited burners of unlimited capacity.
BCU 480
For pilot and main burners of unlimited capacity. Pilot
and main burners can be monitored independently.
LM..F0
Power module without air control interface.
LM..F1, LM..F3
Power module with air control interfaces to connect
an air valve (LM..F3) or actuator IC 40 (LM..F1).
This function is only guaranteed when used within the
specified limits – see page 29 (Technical data). Any
other use is considered as non-compliant.
