3.1 INTRODUCTION
The Mastervolt Masterlink BTM-III provides
extended information about the status of your
batteries. This information includes reading voltage,
current, Ah, time remaining and remaining capacity
in percentage terms of three independent battery
banks. The Masterlink BTM-III has LED indicators
for remote monitoring of the battery level. The LCD
screen also displays direct online data or historical
information. In a single screen the state of charge
and the voltage of three battery banks can be shown
simultaneously. The information on the display is
available in ten languages: English, French,
German, Spanish, Italian, Dutch, Norwegian,
Danish, Swedish and Finnish.
3.2 MONITORING OF THREE BATTERY SETS
The Masterlink BTM-III can monitor up to three
battery banks. Battery bank 1 is monitored in the
most accurate way, i.e. by measuring the
(dis)charge current by means of a shunt. This will
result in a very precise reproduction of the state of
charge.
The status of battery bank 2 and 3 can not be
measured by means of a shunt. If visualisation of the
State Of Charge (SOC) is enabled, the status of
battery bank 2 and 3 can be calculated by means of
a complicated algorithm. Compared to battery bank
1 this method is less accurate, giving you a rough
estimation only
In a system with only two battery banks the input of
the third bank can be used as a backlight input. If
you connect this with the navigational lights, for
example, both will turn on simultaneously.
3.3 FEATURES
• Monitoring of three independent battery banks
(12/24V DC)
• Easy installation
• Shunt (precise measuring of battery bank 1)
• State of charge
• Automatic calculation of Charge Efficiency Factor
(battery bank 1)
• Extensive historical data
• Including ‘abuse counter’ (indicating too deep
and very slow discharges)
• Standard delivery includes grey installation
housing and shunt 500A/50mV
• NMEA 0183 connection
• Read-out possible in ten different languages
3.4 SOFTWARE
A software package (MasterAdjust) can be
downloaded from the website to monitor and log all
information onto a PC. The PC is connected via an
optional MasterBus PC Link. The NMEA output can
also be connected to a PC with this optional
MasterBus PC Link. It is now easy to integrate
energy monitoring into any software package.
Please consult chapter 11 for the software, the PC
Link and the twisted pair connection cable.
