        FAQ
        The error LED is lit See answer
        Explanation 1: Reverse polarity.
        Test: Make sure that the + cable/clamp is connected to the + terminal and the – cable/clamp is connected to the – terminal.

        Explanation 2: Loads are connected to the battery which requires more power than the charger can provide.
        Test: Turn off or disconnect the loads when charging.

        Explanation 3: The clamps are short circuited in Supply mode.
        Test: Separate the clamps.
        No LED is lit when the charger is connected only to the power outlet See answer
        Explanation: One of the LED’s at the lower row should light up when the charger is connected to the power outlet.
        Test: Make sure that there is power from the power outlet.
        is lit for 4 hours and then turns into error mode See answer
        If the battery voltage is not above 12,5V after 4h the charger will turn into error mode, because the voltage has not increased in the way it should have done.

        Explanation 1: The battery is too large in relation to the capacity of the charger.
        Test: Make sure that the battery/batteries size is not larger than the recommendations.
        Test: Try to restart the charger because the charger might need more time to charge the battery.

        Explanation 2: Larger loads are connected to the battery.
        Test: Disconnect the battery and try to charge it without the loads.
        Test: Try to restart the charger because the charger might need more time to charge the battery.

        Explanation 3: If the battery is warm and/or is boiling heavily during the charging, it is most likely due to a defective cell in the battery.
        Test: Change the battery.
        The charger has gone into maintenance mode but cannot see that the recond is completed? See answer
        The Recond program starts with the normal charging program but has a recondition phase inserted after the charging, automatically followed by the maintenance mode. The Recond light “R” on the upper row may be tricky to see, as it will be lit after the third charging lamp, and turns off after the recondition is done, (lasts 0,5h – 4h) and after that the 4th, green maintenance light will be lit.
        is flashing, then turns into error mode See answer
        Explanation: The battery is probably too sulphated to revive. The battery is faulty and it is time to change it.
        No LED’s are lit on the top row when the charger is connected to both the power outlet and the battery See answer
        The LED’s on the bottom row are lit and you can change charging mode. None of the LED’s in the top row, indicating charging status, are lit.

        Explanation: The battery voltage could be under 2+/-0.5V.
        Test: Test the charger on a fresh battery.
        is lit and then turns into error mode See answer
        The analysis phase is testing if the battery can retain the charger given.

        Explanation 1: Large loads are connected to the battery and are draining the voltage.
        Test: Disconnect the battery and try charging again.

        Explanation 2: The battery cannot retain the charge given.
        Test: The battery needs replacing.
        No LED is lit when the charger is connected only to the battery See answer
        Explanation: The plug has to be connected for the LED to be lit.
