10.14.2 Battery charger check
To make this device operate in a
reliable and optimal way, only
following operations are necessary:
−
have all circuit breakers and
outer gauges checked for
proper operation, have the
wiring checked for possible
cracks and for dirty or oxidized components;
−
have the casing removed and checked that the circuit boards are free
from oxidation. Have it cleaned, If necessary, by a deoxidizing
solution;
−
have all electric connections protected by a suitable product (DC4);
−
have the casing installed after the cleaning;
−
check at least once a year the connection of each cable (loose
connections, etc.);
−
keep the battery charger dry, clean, and remove dust to ensure good
heat dissipation.
Charge output
To operate properly, your batteries must not be discharged below 30-
40% of their capacity; therefore, always re-charge them starting from this
charge level.
The battery charger is equipped with temperature sensor installed close
to the batteries. According to the temperature value detected, and
concurrently with the residual capacity of batteries, the battery charger
adjusts automatically the charge voltage, in compliance with the
temperature, increasing remarkably the battery life. Moreover, beyond
the heat compensation, the battery charger can also compensate the
voltage drop, because of the heat dissipation of connecting cables. The
battery charger is equipped with built-in signal light, this activates only if
special adjustment values are exceeded.
a
DANGER
Before operating on the battery
charger, disable the generator
start and the shore power supply.
j
WARNING
All maintenances listed must be executed exclusively by specialized
personnel.
a
DANGER
NEVER clog the air inlets of the cases containing the batteries, because
the natural ventilation of the batteries must always be ensured, to
prevent their overheating.
S
CAUTION
Should the battery voltage drop under 18 V, the battery charger will
supply a current corresponding to the 25% of the maximum one and the
recharge time will consequently increase.
