Electronic compound regulators and complete burner control units from Lamtec. These instruments set new benchmarks in the control of combustion systems. Thanks to the wide variety of possible settings and additional hardware and software options, the units can be adapted for nearly all combustion tasks, from simple monoblock burners to complex power stations.
Lamtec offers a comprehensive range of products, starting with the ETAMATIC for simple combustion facilities, via VMS / FMS for larger installations, all the way to the complete 19" burner control unit. And all this with a universal operating philosophy. Thus, LAMTEC's burner controllers cover the entire spectrum from medium to large burners. Integration of many of the functions needed in combustion systems into one instrument saves wiring and commissioning costs. Choosing the FMS or ETAMATIC considerably reduces the number of external units needed, thus creating a price/performance ratio without peers.

The VMS, FMS and ETAMATIC are tested by TÜV Bavaria. All units comply with the relevant EN standards (EN-298 and EN-230) and thus are licensed across Europe for operation in combustion systems. Over and above that, they meet in part the more stringent demands of TRD-604. They are licensed under DIN-DGVW. The integral FMS leakage monitor meets the requirements of DIN V3447 and of prEN1643. The integral output regulator complies with DIN 3440.

VMS compound management system 
Universal electronic fuel/air compound control unit for all types of combustion systems. TÜV-tested, licensed for TRD 604 installations. The VMS is the VR 4 ratio controller's successor. It includes the electronic compound controller with 4 or 5 servo outputs. The analogue inputs have 10-bit resolution. This permits actuator accuracy of < 0.1° with a 90° motor.

All operational and error messages are displayed in plain text. Up to 20 points can be input per curve. The unit's configuration can be changed on site through password-protected parameters. In the standard configuration, the unit has 2 curve sets (e.g. for oil and gas); 4 or 8 curve sets are available as options. The options of introducing corrections have been widely extended. This further improves the ability to implement special installations.

 The unit has a PC interface. Curve and parameter data can be saved by means of a Windows 95-based program. As a result, the VMS can be remote-controlled and the curves represented graphically.

In addition, the VMS has a LAMTEC system-bus interface for linking to other new-generation LAMTEC instruments, such as LT 1 / LT 2 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. The following protocols are available:

• Profibus DP
• Interbus-S
• Modbus
• CANopen
• SUCOnet-KO

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 the functional diagram.

FMS combustion management system 
The complete burner controller that meets all requirements. TÜV-tested under EN298/230 and licensed for TRD 604 installations. 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 already included. 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, in addition it also contains the combustion controller, and if necessary, also a leakage monitor. All these functions together 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 any more.

And if you want to save even more on wiring: the FMS is available together with ignition and main flame monitor and with New value/first value signaler, complete with all relay modules built in and wired in a 19" rack .

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. 

Naturally, the FMS is also available together with the LAMTECFlame monitors complete in one housing (FMS with flame monitor).

Other Features:

• The leakage monitor for testing the gas magnetic valves can be set either before start-up and/or after shutdown, as preferred
• Several special features are built-in to facilitate commissioning, for example a special mode to help in adjusting the ignition burner and flame sensor settings.
• Variable pre-venting suppression
• Automatic adjustable restart after malfunction shutdowns
• Temporally separated flushing of the recirculation channels during pre-venting is integrated as per TRD
• Main and ignition flame monitors can be started up separately.

ETAMATIC
Compact electronic fuel/air compound regulation with an integral burner controller. The ETAMATIC was specially developed to control all the processes and functions of monoblock burners. Designed for mounting on the burner, it combines in one compact housing all the functions necessary for burner control. An overview of all the functions can be found under ETAMATIC functional diagram.

In detail:

• Fuel/air compound control with 4 servo outputs
• Burner controller
• Leakage monitor
• Flame monitoring (optional)
• Output regulator
• Operating hours and start-up counter
• A constant servo output for revolution speed regulation of the
• Combustion air blower incl. rev. speed measurement (ETAMATIC S)
• O regulation
• Field-bus link (optional)

Thus, apart from the output section, no additional components are needed at the burner. The ETAMATIC also has an RS232 interface for visualisation and remote control from a PC. With the Windows-based program it is possible to represent curves graphically and to save all the parameters. In addition, the ETAMATIC has a LAMTEC system bus interface for linking up to the LT 1 / LT 2 Lambda transmitters, used to measure O2 content in flue gas and to optimise combustion. The ETAMATIC / ETAMATIC S are designed for continuous operation in accordance with TRD-604-72h.
