E²CON-TE: TEM-Evo Retrofit for
modernizing MWM gas engines

With the experience we gained on well over 10,000 engine controllers for DEUTZ and MWM gas engines, we are confident we have designed the optimum solution for their modernisation. Taking current needs into account and anticipating future challenges. This new engine management system is based on openECS, and is conceived as a risk-free conversion for replacing the TEM-Evo controllers that were delivered as standard equipment on DEUTZ and MWM engines.

New plant concepts and operating modes demand a flexible engine control system that on the one hand can manage operation at the engine's mechanical limits and on the other hand enables an engine to be quickly and simply adapted to new requirements.

Advantages AVAT E²CON-TE

  • Simple commissioning
    TEM-Evo-trained service technicians can exchange the system themselves, commission it and adapt it the plant
  • Delivery
    of a complete scope-of-supply including circuit diagram, installation instructions, functional description, list of limit values and parameter descriptions
  • Web Interface
    to the E²PILOT workstation for direct insight onto the controller from any web-capable client
  • Optional Connection
    to the AVAT VIRTUAL SERVICE CENTER for an overview of all connected plants and to an alarm management system with live status
  • VHPready
    for straightforward integration of the plant into a virtual power plant, without the need for an overriding control system to cover this function


Familiar technology brought right up-to-date

Based on the open and flexible openECS hardware and software components and the robust M1 industrial controller from Bachmann, E²CON-TE offers significantly more scope for individual system adaptation and expansion. Likewise, E²CON-TE enables the control of complete peripheral systems to be readily implemented, or connections into SCADA systems and virtual power plants to be easily realised. Further information about the openECS principle here.

Plug & Run Retrofit
Fast and simple system update by means of a pre-configured control cabinet for direct installation on site. Generator-set cabling can be retained and only renewed when "natural" degradation dictates.

Parameter Conversion
The risk-free update is achieved via a unique parameter converter. The system's major control functions, such as start/stop, emissions control and control of peripherals behave the same after the retrofit as they did before. In this way AVAT optimally minimizes the risk that the modernization of a competitor's system could lead to a deterioration in control functions.

Smart Communication
The connection to the E²PILOT workstation and to E²SERVICE service tool no longer involves serial interfaces but are completely ethernet-based. This enables simultaneous operation.

Extended Parameter Accessibility
More scope for individual system adaptation and expansion to specific operating conditions. The familiar control functions of TEM-Evo have been further optimised and are available in their accustomed quality.

Optimised Operation
The familiar operating concept as well as the parameter views are retained. With the new operator interface of E²PILOT, anyone who knows the earlier system will soon be at ease and confident enough to start work. In addition, with E²SERVICE service technicians have available a comprehensive service and diagnostic tool.

FLEXIBILTY OPTIONS
E²CON-TE is already prepared for the future requirements of the network connection standard VDE 4110 and for the more flexible operation of plants according to BDEW specifications.
