Set the VLVA alarm to a voltage that, if charger output voltage falls below this setting, an alarm will be
annunciated.
High Battery Temperature Alarm (HBTA)
Set the HBTA alarm to a temperature that, if the battery temperature rises above this setting, an alarm will
be annunciated. The temperature compensation (option 2) must be purchased and installed in order for
this alarm to work. If this option is installed the battery temperature can be found in the "Battery
