MSU3.1 is an automatic Generator controller, intended for easy control and management of all necessary functions on Gen-Set applications. The controller can be used with single or three phase generator systems.

The unit is designed with high process power for versatile and accurate control of generator functions. It controls 3 phase or single phase generator voltages while monitoring single phase generator load current.

User can program any of the auxiliary i/o ports for custom applications. The menu offers extensive control for each i/o and all the parameters can be configured via PC, using the ENKO PRO-Link configuration program. All the parameters can also be configured from the front panel controls. SMS messages can be sent, using optional GSM interface module.

Many of the control variables can be displayed as required. The analog sensor characteristics can be adjusted from the menu to adapt any sensor. There are altogether 10 i/o ports available, where each one can be independently configured via program menu.

Load power is also measured and can be used with dedicated functions in the menu. Decisions can be made depending on active and/or reactive power of the load. Total accumulated power is also measured and recorded.

MSU3.1 control module is optimized for enhanced applications, where customer demands are high and allows minimal solutions for all genset applications with high reliability.

  • 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.
