6.34.2 Auto configuration
If the automatic battery test is used, the function must be enabled in menu 6420. When the function is enabled, the battery test will
be carried out with a specified interval, for example, once a week. Completed battery tests will be logged in a separate battery test
log.
INFO
The factory setting in menu 6424 is 52 weeks. This means that the automatic battery test will be executed once a year.
INFO
If "Battery test" (channel 6413) is configured to "X + Start sequence", the alarm "Start failure" (channel 4570) will occur at
the end. If the alarm is left unacknowledged, the genset will not be operational.
6.34.3 Battery asymmetry (6430 Batt. asymmetry)
The reason for making the battery asymmetry test is to determine if one of the batteries is getting weak. The battery asymmetry is a
combination of measurements and calculations.
Set points available:
• T1: The input type to be used for calculation of battery asymmetry.
• RF1: Reference of asymmetry measurement no. 1.
• T2: The input type to be used for calculation of battery asymmetry 2.
• RF2: Reference of asymmetry measurement no. 2.
The following seven battery applications are supported. The shown applications are merely examples – the choice of multi-input (MI)
or power supply input is configurable in menu 6410.
