6. OPERATION CHECK
Once the system is installed, you can test its functionality by performing the following
tests:
1) With the engine switched off, and with all the equipment powered off, check that the
voltage shown on the display relative to the 3Lion battery, is equal to the voltage
measured with the tester positioned on the 3lion poles (tolerance of ± 0.15V).
2) With the engine switched off, and with all the equipment powered off, check that the
voltage shown on the display relative to the engine is equal to the voltage measured
with the tester positioned on the engine battery poles (tolerance ± 0.15V).
3) With the engine switched off, turn on some pieces of equipment on the vehicle, and
check that a negative current is displayed on the display. With the ammeter clamp,
placing it on the wire out of pole 3 of the 3Link, it is also possible to verify that the
current shown on the display is the same as the current displayed on the instrument
(tolerance ± 10%).
4) With all equipment powered off, turn on the engine and verify that the engine battery
voltage rises to between 13.8V and 14.8V. If voltage remains below 13.8V, the engine
battery is likely to be discharged and/or the alternator has an abnormality or, if a
positive current is shown on the display, it indicates that the 3Lion battery is charging
and, in this case, skip to step 5.
5) If the 3Lion battery is not fully charged, and if the check in step 4 has been
successful, check the display for a positive current, and check that the arrow pointing
to the engine battery turns red. With the ammeter clamp, placing it on the wire out of
pole 3 of the 3Link, it is also possible to verify that the current shown on the display
is the same as the current displayed on the instrument (tolerance ± 10%).
7. VERIFIABLE PROBLEMS
If the 3Lion battery has a voltage between 0V and 10V (resulting voltage, also detected on
pins 2 and 3 of 3Link ) , it may be possible that the BMS protection inside the battery has
been operated. This protection occurs for three main causes:
1) Battery voltage has fallen below 10V (e.g. due to excessive discharge).
In this case, provide the 3Lion with a charging source (for example, via external charger,
alternator, etc.).
2) The battery voltage has exceeded 15V (e.g. due to an anomaly of the charger, or
because of some piece of electronic equipment in the system that enters a voltage
greater than 15V).
As soon as the 3Lion detects a voltage below 15V, it resumes working normally.
3) The battery is overheated.
You have to wait for the internal temperature of 3Lion to drop below the safety threshold.
It is difficult to estimate the reactivation time, as it depends on external conditions and the
degree of overheating.
