charged is the number of amps flowing into a
fully charged battery. The more a battery is
charged the less current it requires. If this
current drops below 2 % of the installed battery
capacity (C 20 rating), the battery can be
considered as fully charged, provided the
charged voltage is met as well. If the battery
becomes a lot older (beyond its normal lifetime)
it might start to consume more current when the
battery is fully charged so the meter can not be
reset to zero and efficiency can not be
calculated correctly. This means that this set
point needs to be changed to a higher value if
old batteries are used which are beyond their
economical life but can not yet be replaced. The
"charged" amps can be changed between 1 and
10 % of the installed capacity and the factory
default is 2 %.
Setting the "charged" voltage (A04).
In order to check if the battery is fully charged
several parameters must be met before the
MICC will consider the battery fully charged.
One of the parameters is the minimum voltage
that must be reached. This voltage must be set
according to the lowest voltage of all the
charging devices in the system. This means for
example if the voltage of the battery charger is
14.25 volt and the alternator is 14 volt the
voltage must be set just below the lowest
voltage i.e. below 14 volt.
The above mentioned voltages are measured at
the output terminals of the charging system and
therefore it is necessary for these voltages to be
set approx. 0.4 volt lower to compensate for the
voltage drop in the wiring. In the above
mentioned example therefore the voltage must
be set for 13.6 volt.
Also this value will be automatically set for a
12 or a 24-volt system. The factory settings are
13,6 volts for a 12-volt system or 27,2 volt for a
24-volt system.
Resetting the Ah consumed (A05)
With the fifth of this menu the consumed Ah can
be reset back to zero by the Set-up button for 5
sec. This will only be required if the MICC is out
of synchronisation caused by wrong settings or
if the batteries are replaced.
Only reset the consumed Ah's if you are
sure the batteries are 100 % charged.
Setting the battery voltage (A06)
The last level is used to set the Masterlink
MICC according to the battery voltage of the
main battery. If the Masterlink MICC is powered
up with a full or at least a reasonably charged
battery, the MICC will automatically set the
voltage according to the nominal voltage of the
main battery system. If during power up of the
Masterlink MICC a 24-volt battery was
completely discharged i.e. the voltage was
below the 15 volts, the meter is set for the
wrong voltage. The right voltage can be set with
the Set-up button. The factory default setting is
12 volt.
Return to users menu (A07)
If this level is entered you can return to the user
menu by means of the Set-up button.
