CHARGER FAULT U^ The output voltage is momentarily to high. The charging
is temporarily terminated and restarts after a moment.
Repeated errors causes the charger to shut off
permanently.
Possible causes: Bad connection between the charger and
the battery. Bad connection on the battery. Faulty
thyristor. Faulty pcb.
Measures: Check connections. Check thyristors (see
”Checking thyristors and diodes ”). Check and replace
pcb.
CHARGER FAULT U> The output voltage exceeds the programmed value.
Possible causes: Faulty thyristor. Bad connections. Faulty
pcb.
Measures: Check thyristors (see ”Checking thyristors and
diodes ”) and connections. Replace pcb.
CONNECT BATTERY Battery is not connected or has a back voltage below 6V.
Possible causes: Faulty battery. Bad connection.
Measures: Check battery and connections.
HARDWARE VER ERR Programmed value of ”hardware code” is out of range or
invalid.
Measures: Program a valid value (under ”service ”).
N.b. the current program version does not display the
programmed value of the hardware code.
HIGH DC VOLTAGE The back voltage of the battery connected to the charger
is higher than the programmed value in ”upper start
limit”.
Possible causes: The number of cells is to high. Wrong
value in ”No. of cell”. Wrong value in ”upper start limit”.
A newly charged battery is connected to the charger.
Measures: Check the data plates on the battery and the
charger. Check the programming.
HIGH MAINS The mains voltage is too high.
Possible causes: The charger is connected to the wrong
type of mains connection. Calibration error.
Measures: Check the data plate of the charger. Check
calibration.
