This is the complete burner controller that meets all requirements; type-examination tested. By using a different relay unit and a software module, the VMS compound management system becomes the FMS combustion management system. Thus, the electronic compound regulator comes with a burner controller. This integration saves a great deal in terms of wiring overheads, and reduces the number of error sources. Commissioning the system becomes simpler.
The FMS contains all VMS functions. However it also contains the combustion controller, and if necessary, a leakage monitor too. Together, all these functions reduce the required number of external instruments to a minimum, thus creating a price/performance ratio without peers. When using the FMS with integral leakage monitor, output regulator and possibly rev. speed feedback, almost everything needed for combustion control is integrated into one unit. Safety chains, sensors and monitors are linked directly to the FMS. Additional external regulators or monitoring devices are hardly needed anymore.
Visual data and operation are the same as in the VMS. Control of the magnetic valves, the ignition transformers, the ventilators etc takes place via a special relay module. This allows valves up to 2 A to be switched directly. The FMS has 16 digital inputs, of which 3 are inputs for separate safety chains. Thus, external error sources can be differentiated, identified and displayed.
The controller can be adapted to the widest range of different tasks through simple parameter settings. Many of these can be adjusted on site. Each permitted flame monitor can be addressed via a floating-potential contact.
The unit has a PC interface. Curve and parameter data can be saved by means of a Windows based program. As a result, the VMS can be remote-controlled and the curves represented graphically. A demo version of this remote control and remote display software is available at download register.
In addition, the VMS has a LAMTEC-SYSTEM-BUS interface for linking to other new-generation LAMTEC instruments, such as LT1 / LT2 Lambda transmitters for measuring the O2 content of flue gas and for optimizing combustion.
The VMS can be connected to the control system via standard bus systems.
Other features:
- The last 10 faults are stored and can be called up at any time
- Integral, fuel-referenced operating hours and start-up counter
- Direct link to a Namur sensor for measuring revolution speeds in rev. speed control systems (optional)
- Optional integral output regulator with special functions, such as start-up and shutdown capabilities and weather control
All these innovations notwithstanding, the operating method has remained the same as in the VR.
Curve input is just as simple in the VMS as in its predecessor. A graphic representation of the most important options and functions is shown in selection criteria.
