Electromagnetic brake malfunction replace
The batteries do not last as
long as usual the battery poles and terminals are
dirty and oxidised clean and grease the poles and
terminals, charge the batteries
the level of electrolyte is low add distilled water, topping up each
element
according to the
instructions
the battery charger does not work or
is not adequate see the battery charger instructions
there are considerable differences
in density between the various
elements of the battery replace the damaged battery
The battery runs down too
rapidly during use, even
though it has been charged
with the correct procedure
and at the end of charging
it is evenly charged when
tested by a hydrometer. the battery is new and does not
provide 100% of the expected
performance the battery must be run in by
performing
20-30 complete
charging and running down cycles
to
obtain the maximum
performance
the machine is used for the
maximum
of its power for
continuous periods and the run time
is insufficient
when permitted and possible, use
batteries with a higher capacity or
replace the batteries with others
already charged
the electrolyte has evaporated and
does not completely cover the
plates add distilled water, topping up each
element until it covers the plates
then recharge the battery
The battery runs down too
rapidly
during use,
charging with the
electronic battery charger
is too fast and at the end
the battery provides the
correct voltage (about 2.14
V per element without
load), but appears to be
uniformly
not charged
when tested with a
hydrometer
the battery supplied by the
manufacturer already filled with acid
has been stored too long before
being charged and used for the first
time
if recharging with the normal
battery charger is not effective,
perform a double charge:
- charge it slowly over a 10 hour
period at a current of 1/10 the
nominal capacity for 5 hours (eg.
for a 100Ah(5) battery the current
must be set at 10A, using a
manual battery charger);
- rest for one hour;
- charge it with the normal battery
charger.
At the end of charging with
the
electronic battery
charger, the battery does
not provide the correct
voltage (about 2.14 V per
element without load) and
appears to be uniformly
not charged when tested
with a hydrometer
the battery has not been connected
to the battery charger (for example,
because the low voltage battery
charger
connector has been
incorrectly connected to the
machine connector)
connect the battery charger to the
battery connector
the battery charger and socket to
which it is connected are not
compatible. make sure the characteristics of
the power supply shown on the
battery charger rating plate are the
same as those of the mains
electricity supply.
the battery charger has not been
correctly installed taking into account the actual
voltage available at the power
socket, make sure that the
connections of the primary of the
transformer inside the battery
charger are correct (consult the
battery charger manual)
