Error messages and notifications in the user interface

When error messages and notifications are displayed in the user interface, always follow the instructions on how to proceed. Examples of error messages are alerts of deviations in temperature and capacity, such as:

  • High propulsion unit temperature
  • High battery compartment temperature
  • Low insulation resistance
  • Overheated motor controllers
  • Limited Propulsion Power
  • Propulsion power can be automatically limited for different reasons, including:
CauseIndicationDescriptionCorrective action
Overheating of componentA warning message appears on the user interface. For example: "Motor controllers to hot. Propulsion will be limitedor lost."Top speed is reduced. Take-off might not be possible.Normal operation is automatically resumed after the component has cooled down.
Low battery chargeA warning message appears on the user interface. For example: "Low Battery. Speed is limited. Seek harbor immediately."Battery charge is critically low (below 5%). Propeller speed is limited to 1500 RPM. Taking off is not possible. Foiling can be continued until battery charge is 1%.Return to port and charge the battery to resume normal operation.

Low state of charge

Low state of charge is indicated in the user interface as follows:

  • 20% – “battery low”
  • 10% – “battery critical low”
  • 0% – “battery empty”

Software updates

The C-8 has multiple onboard computers and systems that manage all aspects of the boat. The software is updated regularly "over the air" to introduce new features, enhance performance and resolve issues.

For optimal performance and safety, always keep your boat updated with the latest software.

When a new update is available, you will receive a notification. You can choose when to install and update via the boat’s user interface.
