Battery Charger Logic

The Power Zone 410 controller comes equipped with a
12V 5A internal battery charger. The internal battery
charger is enabled once on startup, and when the battery
voltage drops below 12.7 V for at least five seconds. The
internal charger is also enabled when an external charger
is faulted, or the battery system is incorrectly configured.
When enabled, the charger outputs as much current as
the batteries can take up to the max current for a full
charge cycle of 26 hours.
The charger is disabled after completing the charge
cycle. Additionally, the charger is disabled when the gen-
set is cranking or running, the battery voltage is less than
7 V or greater than 16 V, or if the system has been config-
ured for an external battery charger.
At the end of a full charge cycle, the internal charger per-
forms a battery health check. If the battery voltage is
measured less than 12.5 V then a charger fault is raised.
If the digital input GOT_T1 is disconnected, a Battery
Charger Missing AC fault will be raised indicating the in-
ternal charger does not have power.
There are two types of faults which can be detected when
using an external charger. The first is the fault indicated
by the digital input EXT CHARGER FAILED. This fault in-
dicates the external charger has lost power. The second
fault occurs when the external charger has power but is
not outputting current. This triggers when the battery volt-
age drops to 12.7 V while the external charge current is
below 250 mA. This condition must persist for at least
three seconds before a fault is raised. When the external
charger is in a fault state, the battery charger will revert to
the internal charger so battery charging continues.

Loadshed Logic

When enabled, if the generator becomes overloaded, pri-
or to a shutdown alarm on overload, the generator will de-
crease engine speed to create a frequency drop of 3 Hz.
This will enable a Generac loadshed module to perform
it's loadshed sequence by recognizing the dip in
frequency.
