1 General Infomation
1.3 Purpose
Purpose FMS 4 /
FMS 5 The FMS 4 / FMS 5 Combustion Management System is a control unit for FMS 4 / FMS 5 com-
bustion systems.
Brief description The FMS 4 adjusts up to four control elements as a function of a control variable (generally
the burner load) according to freely programmable curves.
The FMS 5 adjusts up to 5 control elements as a function of a control variable according to
freely programmable curves.
2 sets of curves (e.g. for oil or gas) can be filed as standard, with the option for 4 or 8 sets of
curves.
Examples of possible control elements:
–
combustion air damper
– re-circulation fan
– combustion air fan
– flue gas damper
– fuel quantity
– flue gas fan
– atomiser steam
Up to 20 points can be programmed for each channel. The display is relative between 0 and
999.
The FMS has two correction inputs for shifting the setpoint curves, allowing a feedback control
(e.g. O
2
control unit to optimize combustion) to be connected up.
Each output is freely configurable, either three-point step control element output for direct ac-
tuation of a motor or constant output (on the FMS 5 the 5th channel is always constant). The
constant output can be set to any of the following variables:
–
current signal 0 ... 20 mA
– current signal 4 ... 20 mA
– voltage signal 4 ... 20 mA
In the FMS 4 a so-called monitor output is integrated. Using the 4...20 mA signal with this out-
put, an internal value (such as the load position of the burner or position of the gas control
element) can be output.
The FMS has one serial interface for remote control/ display via PC (Windows software avail-
able separately) and for connection to other system components via BUS (e.g. fault message
system, O
2
control).
Connections for Profibus, Modbus, Ethernet, Interbus-S and CAN-BUS are available as op-
tions. Other BUS systems on request.
