Brief Description
The Burner Control FA1 is suitable for control of burners and combustion systems for gase
-
ous, liquid and solid fuels, with permanent operation, also in hot air generators.
Connections for Interbus-S, PROFIBUS DP, CANopen, TCP/IP (Modbus TCP) and Modbus
RTU are available as optional equipment. The connection of other plant components e.g. O

trim is by the LAMTEC SYSTEM BUS interface to a 9-pole Sub-D connector.
The operation is via optional PC software or programming unit. As display for end user, a cus
-
tomer interface is connectable by LAMTEC SYSTEM BUS. The operation by PC software is
described in a separate manual
The FA1 continuously monitors its own functions and those of the connected control elements.
230 V outputs:
– actuation of the gas valves
– actuation of the oil valves
– actuation of the oil pump/rotary atomiser
– actuation of the ignition valve and the ignition transformer
– fan release
– fault message
– OPEN/CLOSE control signals (three-point-step or 4 ... 20 mA) for the mechanical fuel/air
ratio control
External signals to the FA1 are transmitted via floating contacts or chains of contacts.
The following signals can be pre-set:
– 3 separate safety interlock chains
– gas < max
– air pressure monitor
– pre-purge suppression
– minimum gas pressure monitor (for valve leakage test) gas >min
– flame signal
– burner on
– fuel selection
– oil pressure min / atomiser air pressure
– oil pressure max
– ignition position acknowledgement
– internal burner firing rate controller in combination with the control output
