Maximum time
Maximum absorption timer
Examples of cases when to adjust:
• Extension of the absorption time to do some
intentional overcharging to regain lost capacity.
• Shorten the time if you stop and start the engine
often each day.
• Temporary time reduction for testing purposes.

Float
4
Voltage
Float voltage; If the float voltage is set near 13.0V,
you may have to switch on some DC loads to get
the alternator to turn on because it takes some
time for the voltage to settle from the higher
absorption voltage.

Option to reset to factory settings
Lock setup
Button to lock the configuration settings. With the configuration locked, only the language

1
Only in combination with alternator temperature sensor.
2
All RPMs in this group are Alternator RPMs.
3
The number of Pool pairs is only needed if RPM values are required in MasterBus.
4
Can be modified if battery type is "User defined".
5
This will force the field current to 0%. Note: with older firmware it would not drop below 20%. Therefore, the new behavior of
this setting may affect existing installations. An external tachometer would read 0 RPM while the alternator is still spinning!
6
For a 24V system, multiply the voltages by two.
