5.2.1 Input nominal voltage
Used to set the nominal input voltage on the input connector. Used to generate the
input under voltage and over voltage alarm. See §6 for more details.
Default
: 24V
Range
: 11V
… 28V
Resolution
: 0.1V
5.2.2 Battery chemistry
Used to set the chemistry of the battery. The system support Lead Acid, Nickel and
Lithium batteries. For Lithium the battery pack used must include the protection and
balancing circuitry.
Default
: Pb
Choices
: Pb, NiMh (CC/CV), Lith.(CC/CV)
5.2.3 Battery nominal voltage
Used to set the nominal battery voltage.
Default
: 24V
Range
: 11V
… 28V or input nominal v20%

: 0.1V
5.2.4 Battery capacity
Used to set the nominal battery capacity of the battery. The internal Coulomb
counter uses this value to indicate the state of charge of the battery.
Default
: 2Ah
Range
: 1.
2Ah … 150Ah

: 0.1A
5.2.7 Battery deep discharge voltage
Used to set the deep discharge voltage of the battery. If the measured battery
voltage drops below this value the system disconnects it in order to prevent
irreversible damage.
Default
: 18V
Range
:
8.2V … battery nominal voltage -25%
