•
Overvoltage: voltage over 16V is recorded on the
terminals, probably due to too high a voltage of the
external charger.
•
Short circuit.
•
High current consumption beyond the limits set
out in the table (...refer to the table in the
'DISCHARGE' chapter)
•
Cell overtemperature: over the allowed range.
•
Internal BMS overtemperature.
•
Internal BMS fault.
To restore normal battery operation, press the ON/OFF
button (Fig. 2 - Ref. G). When the button is pressed, the
system performs a check-up and if the problem has
been solved, the LED (Fig. 1 - Ref. C) returns to green
flashing and the voltage on the terminals is restored. In
the event of a persistent fault, the battery would remain
in alarm status. In the event of a persistent fault,
contact an authorized NDS dealer.
The alarm is automatically reset by the battery,
however, it may persist for some time (from a few
seconds to several minutes) depending on the anomaly
detected. Specifically:
1. One or more cells with voltage above the permitted
limits. The alarm is deactivated when the cell
voltage returns to operational levels. On the BUS
display (DTB 01) and on the mobile app, the
notification "Cell voltage(s) high" appears. On
deactivation of the alarm, it is recommended to
discharge the battery by a few Ah (3 Ah are
sufficient).
2. One or more cells with voltage below permissible
limits. The alarm is deactivated when the cell
voltage returns to operational levels. On the BUS
display (DTB 01) and on the mobile app, the
notification "Cell voltage(s) low" appears. WARNING:
