Stop Charge event
Before the battery reaches the limits of the operating specifications, the Stop Charge event is triggered.
When configured, this event forces the Mastervolt charger to switch to the float stage. The charger will
use a lower charger voltage or, in case of parallel connection, switch off. The event will be active for 10
minutes.
WARNING!
If multiple charging devices are used to charge the battery (for instance both an AC powered
charger and an alternator) then the Stop charge event must be configured for each charging
device. The settings depend on the used charger because different chargers have different state
options. Check the manual of the used charger for how to switch the charging state.
In case of a battery bank, this must be done for each battery.
Stop charge can also be selected by setting DIP switch 3
ON
. In this case, all connected Mastervolt
chargers will stop charging when a 'Stop charge'-condition is met.
