FMS combustion management system
System that merges an electronic burner sequencer with fuel-air ratio control for up to 5 actuators in one device

- CO/O₂ control
In a single device, FMS combines an electronic burner sequencer with electronic fuel-air ratio control for up to five actuators. CO/O₂ control is built in; load control and the valve leakage test are optional, and a LAMTEC flame monitoring system can be linked to it. Its fail-safe design gives flexibility of a kind usually only a PLC provides. Because safety chains, sensors and switches wire straight to the FMS, fewer relays and cables are needed, and a small control cabinet on site is often enough.
Each actuator can be driven by a 0/4…20 mA current signal or as a three-point step drive, except channel 5, which takes a current signal only. Two correction inputs shift the set fuel-air curves during operation, for example to offset changes in intake air temperature. Two fuels can be fired together at a variable mixing ratio, the change from one fuel to the other is controlled and gradual, and an oil gun purge function is included. Plug-in cards adapt the analogue inputs to different physical quantities.
Operating and fault messages are shown as plain text in the user's language, and an optional first-out and process indication module can be connected to display them and help trace safety chain faults. Running time is logged per fuel and the number of starts per operating mode. The unit is operated directly on its front with password protection, or remotely through the PC interface. FMS 4 and FMS 5 are certified to DIN EN 298:2012-11.

Relay modules
For burner management, the 660R0016 V4.3 relay module turns nine digital signals from the FMS into twelve 230 V AC output signals, covering outputs such as main gas, oil and ignition valves, ignition transformer, fan and fault. Relay modules are also needed to drive the actuators with three-point step control; different types are chosen according to motor torque.
LSB I/O modules
Analogue and digital input/output modules for the optional LAMTEC SYSTEM BUS interface. Additional bus signal inputs and outputs are assigned over LSB, with 12 analogue inputs available on the LSB side. LSB links LAMTEC devices with little wiring, and DIN-rail fieldbus modules are driven over it using a settable address.
