  • 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.

  • AMF / MSU Series - What is the difference between a Manual Start Unit (MSU) and an Automatic Start Unit (AMF)?

    While the Manual Start Units (MSU) monitor and control only the Generator, the Automatic Mains Failure Units (AMF) are capable of monitoring and controlling both Mains and Generator. The MSU will wait for a remote start signal or a manual command from the front panel to start the Engine. Alternatively the MSU's can be used together with an Automatic Transfer Switch (Monitors the Mains and Generator and handles the transferring of the load) and the system can have similar capabilities to an AMF unit. 

  • EBC Series - How can the output voltage on EBC Series Battery Chargers be adjusted?

    EBC 1205, EBC 1210, EBC 2405 and EBC 2410 models have fixed output voltages and can not be adjusted after production. However, because the voltage is adjusted by the factory, it can be adjusted to customer specifications if indicated while ordering. 

    EBC 2420 and EBC 2440 models have on board voltage adjustment trimmers where the user can adjust the output voltage to their specification. Please follow the EBC Series User Manual for this process. The manuals can be accessed from the Documents tab on the related product pages.

  • EBC Series - What is Boost Charge and where is it used?

    Boost Charge or Cell Equalization function increases the output voltage while decreasing the charge current. It is activated externally and can be used periodically in order to replenish the battery condition and charge hold capacity. Please note that Boost charge function has to be used according to the battery manufacturers instructions! 

    Boost Charging will be activated according to the table shown below. During Boost charging, the charger terminal voltage will increase but the but the charge current will be reduced to 50% of its rated output capacity in order to protect the batteries from getting damaged. During Boost charge period, boost charge control input must stay active. 

    EBC 1205 - EBC 1210                    Connect Boost Charge input terminal directly to the battery positive terminal

    EBC 2405 - EBC 2410                    Connect Boost Charge input terminal directly to the battery positive terminal

    EBC 2420 - EBC 2440                    Connect Boost Charge input terminal directly to the battery negative terminal

    Boost charge characteristic is shown in the graph below. The boost charging function acts according to the battery manufacturers specifications. 


  • EBC Series - What happens if the battery terminals connected to an EBC Series Battery Charger are reverse polarity?

    The EBC Series Battery Chargers provide reverse polarity protection function. If the battery terminals are connected in reverse polarity, chargers will trip its output fuse for protection. The 5A and 10A models (EBC 1205, EBC 1210, EBC 2405 and EBC 2410) have internally fitted fuses for protectionbut the 20A and 40A models (EBC 2420 and EBC 2440) have internal semiconductor controlled reverse polarity protection adn this requires no service. The units will recover from protection mode, after the reverse polarity connection is removed.

    Please refer to the table below for more information on fuse ratings. For more information regarding Reverse Polarity Protection function, please refer to the EBC Series User Manual which can be accessed through the Documents tab on the related product page.

  • EBC Series - What is Power De-Rating?

    EBC 2420 and EBC 2440 chargers are protected with power de-rating, starting at 60ºC ambient temperature and reducing down to zero power at 70ºC. Power derating curve is shown in the below diagram:


    Please note that only EBC 2420 and EBC 2440 Battery Chargers provide the power de-rating function. 


    So with power de-rating the rated output will be provided fully upto 60ºC ambient temperature. Then between 60ºC and 70ºC ambient temperature the output power will be de-rated and at 70ºC ambient temperature the unit will shut-down in order to protect itself. Once the ambient temperature drops below 70ºC the unit will power-on and continue its operation. This feature provides exceptionally reliable operation under harsh temperatures. 

  • EBC Series - How can higher output voltages or current capacities be achieved in EBC Series Battery Chargers?

    The EBC series Battery Chargers have the capability of being able to be connected in series or paralels. This is especially important for achieving higher volts and amps. By connecting chargers in parallel, the current capacity can be increased and by connecting chargers in series, the output voltage can be increased. Please note that series and parallel connections must only be made using the same models!

    As an example by making a series connection between 2 units of EBC 1205 (12V 5A) the user can achieve an output voltage of 24 volts and a current capacity of 5 amps. On the other hand, by connecting 2 units of EBC 1205 in parallels, an output voltage of 12 volts and current capacity of 10 amps can be achieved. Please refer to the EBC Series User Manual for more information parallel and series connections. The document can be reached from the Documents section of related product page.
