Shore power switch-over using the fpControl system


Note: This function is not available with every generator. Check in each individual case whether the function can be used with your generator.

Introduction to the topic

You can use the shore power switch-over to automatically switch the supply of your on-board network between the shore network and the generator. This switch-over is used if the mains voltage fails. When the mains voltage is restored, the switch-over can switch back to shore power.

Functional description of the shore power switch-over

The »fpControl Measurement Unit – MM-3« (fpControl MM-3) measures the electrical data of the shore power connection. It measures the AC voltage and the AC current in 3 phases. These electrical values are made available on the fpCAN. A second fpControl MM-3 measures the electrical parameters of the generator in the same way.

The Paralleling Device ensures the parallel connection of shore power and generator.

When the generator is off and the shore power is safely available within its electrical limit values and for a specified time, the shore power is switched on.

With the start / stop button of the utility panel you can request the switch-over to shore power.

If the shore power is no longer available within its electrical limit values and for a specified time, the shore power is switched off. The generator is started via remote start. The generator starts automatically if the mains voltage fails. Shore power has priority.

Settings for the system components

Settings for the »fpControl GC-S«

Activating the parallel mode

In order to connect the generator in parallel with the shore power connection, the »fpControl GC-S« must be switched to »parallel mode«.

The »fpControl GC-S« can be set to »parallel mode« using the service menu of the »fpControl CP-G« on the Generator side.

Requirement: You must enter the service password or have admin rights while the function is being called.

Function call: service > parallel mode

Step by step guide

  • Open menu “service”.
  • Enter the service password.
  • Select “parallel mode” and confirm.
  • Select “on” and confirm.

Result: The »fpControl GC-S« is set to »parallel mode«.

Activating the automatic start mode

So that the generator can be started automatically when the shore power fails, the automatic start mode of the »fpControl GC-S« must be activated via the generator panel.

Function call: generator > autostart > turn on / off

Step by step guide

  • Open menu “generator”.
  • Select “autostart” and confirm.
  • Select “turn on / off” and confirm.
  • Select “on” and confirm.
  • Select “confirm”.

Result: The automatic start of the »fpControl GC-S« is activated.

Settings for the Paralleling Device

If a Paralleling Device is connected to the fpCAN, you will see the menu item »paralleling-device« in the main menu of the panel.

Note: This menu item and all its sub-items are only displayed if the Paralleling Device is present in the fpCAN bus.

Operating Mode

Setting the Operating Mode for the automatic shore power switch-over.

Function call: paralleling-device > mode of Operation > mains <> gen (auto)

Step by step guide

  • Select “mode of operation” and confirm.
  • Select “mains <> gen (auto)” and confirm.
  • Select “confirm”.

Result: The Operating Mode of the Paralleling Device is set to automatic shore power switch-over.

Steady off

You can set the time after which the Paralleling Device should recognize the failure of the mains voltage as a »mains failure«.

Function call: paralleling-device > mains switching > mains: “steady off”

Parameter: Time [0 s to 6000 s]

Step by step guide

  • Select “mains switching” and confirm.
  • Select “mains: steady-off” and confirm.
  • Set the time value and confirm.
  • Confirm the completion of the action or cancel.
    The option “cancel” leads back to the settings page.

Result: The time for “mains: steady-off” is set.

Steady on

You can set the time after which the Paralleling Device should recognize the return of the mains voltage as “restored”.

Function call: paralleling-device > mains switching > mains: “steady on”

Parameter: Time [0 s to 6000 s]

Step by step guide

  • Select “mains switching” and confirm.
  • Select “mains: steady-on” and confirm.
  • Set the time value and confirm.
  • Confirm the completion of the action or cancel.
    The option “cancel” leads back to the settings page.

Result: The time for “mains: steady-on” is set.

Generator Minimum Runtime

You can specify that the generator should run for a minimum time after the mains voltage has failed. When the shore power is available again, the Paralleling Device automatically switches back after this time has elapsed.

If the value for the minimum runtime of the generator is set to “0 s”, the automatic switch-over to shore power is deactivated. The generator then runs until the shore power switch-over is requested via the start / stop button on the utility panel.

Function call: paralleling-device > mains switching > gen: min. runtime

Parameter: Time [0 s to 6000 s]

Step by step guide

  • Select “mains switching” and confirm.
  • Select “gen: min. runtime” and confirm.
  • Set the time value and confirm.
  • Confirm the completion of the action or cancel.
    The option “cancel” leads back to the settings page.

Result: The Generator Minimum Runtime is set.

Settings for the »fpControl MM-3« (Utility Module)

In order to use the »fpControl MM-3« on the Utility Side as a utility module, a few settings must be made.

Requirement: You must enter the service password or have admin rights while the function is being called.

Function call: service > show system-devices

Step by step guide

  • Open menu “service”.
  • Enter the service password.
  • Select “show system-devices”.
  • Select “dev-id 3” and confirm.
  • Select “3Phase Mains” or “1Phase Mains” dependent on the mains and confirm.
  • Select the current sensor type and confirm (choose the option “INTERNAL” if internal current sensors are used).
  • Select “BUS ENABLE” and confirm (in this mode, the boost output can be set via the CAN bus).
  • The changes are being applied.

Result: The »fpControl MM-3« is configured to be used as Utility Module.
