The Automower transformer supplies power to the charging station and is connected to a standard electrical outlet, extended with a low-voltage cable.
It provides power to the robot during charging and to the circuit board in the charging station, which in turn supplies power out to the loop, allowing the Automower to respond to the electromagnetic field created by the loop and function correctly.
If the transformer is damaged, the Automower loses contact with the loop and immediately displays an error message 'No loop signal'. With the help of our guide, you can troubleshoot your Automower transformer with a multimeter without further knowledge. It is also noticeable that the Automower transformer might be defective if the light in the charging station is off. It should always be lit as long as everything is correctly connected. If it lights up green, it means that the loop is functioning and that everything is correct.
A blue flashing light indicates that there is a loop break, for example. You can read more about what the different colours in the charging station mean here.
