Universal electronic fuel and air ratio control unit (VMS) for all types of combustion systems. TÜV-tested, licensed for TRD 604 installations. The VMS is the VR4 ratio controller's successor. It includes the electronic fuel and air ration control system 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 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:
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.
