between the charger and the battery to be charged. This is done via a digital display on which the error code is shown. The
following displays may appear in case of faults during the charging procedure:
Display
Reason
Solution
The terminals of the output cables are not con-
nected to the battery correctly. Possible reverse
polarity.
Connect the clamps correctly and recommence
the charging procedure (see “Use of the charger”).
“Battery voltage too low. (Attempt made to charge
a 12 V battery with a charger set to 24 V.) Battery
voltage too high. (Attempt made to charge a 24 V
battery with a charger set to 12V.)
Check the voltage of the battery.
Ensure the settings are correct. Otherwise the
battery is likely faulty.
Battery charger faulty.
Have the battery charger checked by a trained
specialist.
The battery is not capable of accepting charge
after a set time has elapsed.
Battery likely defective.
