MSU 5.1 is designed with enhanced applications in mind and equipped with all the necessary hardware and software to fulfill this demand.

The unit is equipped with an ARM Processor for high performance. All the Mains and Generator parameters are measured, processed and executed simultaneously, which in return allows enhanced functions for single and multiple Gen-Set applications.

System hardware allows the user to interface with high demanding applications, where high number of peripheral control is required. The system software also carefully designed in order to allow dedicated functions to be characterized for a particular application. Simple logic functions can also be executed on the auxiliary inputs and outputs, hence reducing the number of peripheral instruments.

The controller is equipped with multiple communication ports for enhanced interface with external control systems. RS232/485 can be used for on-site system configuration as well as remote control and monitoring of the system while integrated CAN Bus can communicate with engine ECU module. The system can also be interfaced with ENKO external i/o expansion modules for applications where specific dedicated hardware control is needed.

Front panel design includes 3 analog displays for Engine temperature, Oil pressure and Fuel level indication. Functions can be made to operate on these measured analog values. In the standby mode, the unit can also measure and control the engine body temperature. The load can be controlled both manual and automatic, where both MCB and GCB contactors can be controlled from the front panel.

The system can be used for multiple Gen-Set applications, where one can be selected to be master and allow to control the others as slave units. MSU5.1 allows remote programming, monitoring and GSM interface with any external control system.

SUPPORT
  • Which models have electronic engine capabilities?

    Today most Electronic Engines comunicate over CanBUS protocol (some engines like Cummins communicate over ModBUS), thus the control panel should contain a CanBUS communication port in order to support Electronic Engines. ENKO has 4 models which support CanBUS communication which are AMF 5.1, AMF 5.2, MSU 5.1 and the MSU 5.2. For detailed information on these models please visit the products page.

    In the case where the Engine Control Unit communicates over ModBUS protocol, a panel with an RS485 port will be suffucient for communication with the engine. Please check the engine manufacturers user manual to see which protocol the ECU communicates with. 

  • What are the requirements for configuring the AMF/MSU series controllers via ENKO PC Configuration Suite?

    In order to connect an AMF/MSU controller to the PC, a TTL/USB convertor cable which can be ordered from ENKO is required. Besides the convertor cable the Configuration Suite will require Microsoft .Net Framework 4.0 or better to be installed first. This is a licence free software and can easily be installed from Microsoft.com website or can be installed from the ENKO PC Configuration Suite (Just click yes when prompted during installation).

    The ENKO PC Configuration Suite can be downloaded from our website. Just visit the Software tab on the related product page.

    Models currently supported by the PC Configuration Suite are AMF 3.1, AMF 3.2, AMF 3.4, AMF 3.4L, AMF 5.1, AMF 5.2, MSU 3.1, MSU 3.4L, MSU 5.1 and MSU 5.2.

  • The MCB and GCB buttons on the panel are not functioning. Why?

    The MCB and GCB control is provided on the front panel. These buttons are designed in two different ways. In the AMF 3.4L, AMF 5.1, AMF 5.2, MSU 3.4L, MSU 5.1 and MSU 5.2 models, there are dedicated contactor open and contactor close buttons for the MCB and/or GCB. On the other hand the AMF 3.1, AMF 3.2, AMF 3.4, AMF 4.2, AMF 5.1, MSU 3.1, MSU 3.2, MSU 3.4, MSU 4.2 and MSU 5.1 models these buttons are designed as toggle buttons. 

    The MCB and GCB control buttons will NOT function in AUTO mode. This mode is where the AMF/MSU panel has the control of the contactors and therefore the MCB/GCB buttons are disabled. In order to take control of the MCB and GCB contactors the user must take the AMF/MSU panel into MAN or TEST mode. The contactor buttons will function only in these modes. 

    Another reason why the buttons may not be functioning is the connection mistakes. Please check and make sure the contactors have been connected to the corresponding terminals on the AMF/MSU panel. In order to obtain the connection diagram, please check the Documents tab in the related product page or check the User Manual.
