Temperature LED is lit
Explanation Multi XT 14000: DC interruption or short circuit in the cable.
is flashing, then turns
Explanation MXT 14: This is normal, the LED is on indicating that the temperature sensor is activated. If the LED is turned off here is a DC interruption or short circuit in the cable.
Explanation: The battery is probably too sulphated to revive. The battery is faulty and it is time to change it.
Temperature LED is flashing
Explanation: The temperature is above + 65 °C. The charging is interrupted. Press the MODE button to restart charging when the temperature has dropped below + 65 °C.
No LED’s are lit on the top row when the charger is connected to both the power outlet and the battery
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.
No LED is lit when the charger is connected only to the power outlet
Explanation: The battery voltage could be under 7V.
Test: Try to charge the battery in Supply mode for approximately 5 min. Then try regular charging.
Test: Test the charger on a fresh battery.
Explanation: One of the LED’s at the lower row should light up when the charger is connected to the power outlet.
Temperature LED is lit
Test: Make sure that there is power from the power outlet.
This is normal, the LED is on indicating that the temperature sensor is activated.
The charger has gone into maintenance mode but cannot see that the recond is completed?
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.
The error LED is lit
Explanation 1: Reverse polarity.
is lit and then turns into error mode
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.
The analysis phase is testing if the battery can retain the charger given.
is lit for 4 hours and then turns into error mode
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.
If the battery voltage is not above 25,5V after 4h the charger will turn into error mode, because the voltage has not increased the way it should have done.
No LED is lit when the charger is connected only to the battery
Explanation 1: The battery is too large in relation to the charger capacity.
Test: Make sure that the battery/batteries are 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 charging, 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 a defective cell in the battery.
Test: Change the battery.
Explanation: The plug has to be connected for the LED to be lit.
