10.5 PEUKERT EXPONENT BATTERY BANK 1
The Peukert exponent can be set according to the type of battery installed (see
chapter 11.3 for more information). Do not change this setting without extended
knowledge of the installed batteries
Factory setting: 1.27
Adjustable range: 1,01 …1,50
10.6 RESET HISTORICAL DATA BATTERY BANK 1
All historical data of battery bank 1 (parameters as specified in chapter 8.1 till 8.11)
will be reset when Set is held for three seconds.
If new batteries are installed, the historical data of the old batteries needs to be
erased to leave only historical data from the newly installed batteries.
10.7 CHARGE AMPS FOR FULL BATTERY
In order to check if the battery is fully charged several parameters must be met
before the Masterlink BTM-III will consider the battery fully charged. See chapter
11.4 for additional information.
This percentage expresses the charge current related to the battery capacity (C20)
below which the battery is considered to be full, provided the float voltage (see
chapter 10.8) is met as well. Example: If the battery capacity is 200Ah, and this
percentage is set to 2.0%, the battery is considered to be full when the charge
current has dropped below 200 x 2.0%,= 4 Amps.
If the battery becomes a lot older (beyond its normal lifetime) it might start to
consume more current when the battery is fully charged. 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 have not been replaced yet.
Range: 1…10%
Default setting: 2.0%
10.8 FLOAT VOLTAGE
Another parameter that must be reached before the Masterlink BTM-III will consider
the battery fully charged. This voltage must be set according to the lowest float
voltage of all the charging devices in the system. This means for example if the float
output voltage of your battery charger is 13.25V and the output voltage of your
alternator is 13.8V the voltage must be set just below the lowest voltage i.e. below
13.25 volt.
Lower this value by 0.1V if your Masterlink BTM-III does not return to 100% after a
long period of charging,
See also chapter 11.4 for additional information.
Factory setting: 13.2V/26.4V depending on the nominal battery voltage. When a
Mastervolt battery charger is applied, you don’t need to change this value.
Adjustable range: 12.0…14.0V/24.0…28.0V
