Introduction to the topic<\/h3>\n\n\n\n

With the tank refill function of fpControl you can refill the integrated tank of the generator with diesel fuel from a separate additional tank. <\/p>\n\n\n\n

Functional description of the tank refill<\/h5>\n\n\n\n

The tank refill function has two different operating modes: <\/p>\n\n\n\n

    \n
  1. You can configure the multifunction output 2 (5 A)<\/a> of the \u00bbfpControl GC-S\u00ab directly as an output for the external fuel pump. The output then switches the fuel pump on and off depending on the filling level supplied by the CAN bus tank sensor. <\/li>\n\n\n\n
  2. You can configure one of the multifunction inputs<\/a> of the \u00bbfpControl GC-S\u00ab so that you can switch the tank refill function on and off via this input. In this case the multifunction output (5 A) of the \u00bbfpControl GC-S\u00ab is automatically configured as an output for the external fuel pump. The output then switches the fuel pump on and off depending on the status of the digital input AND the filling level supplied by the CAN bus tank sensor.
    The procedure in detail:<\/strong> The \u00bbfpControl GC-S\u00ab evaluates the status of the multifunctional input. If this input has the status \u00bb0\u00ab, the tank refill function is switched off. If it has the status \u00bb1\u00ab, the multifunction output for the external fuel pump is switched on when the     threshold for \u00bbrefilling\u00ab<\/a> is reached. If the threshold for \u00bbstop refilling\u00ab is reached, the output is switched off.
    There is one special feature in this case<\/strong>: When you switch on the digital input, the external fuel pump is switched on in any case and the integrated tank of the generator is filled to a level of 100 %. This takes place regardless of the filling level supplied by the CAN bus tank sensor.<\/li>\n<\/ol>\n\n\n\n
