5.2.8 Battery low voltage
An alarm is generated if during discharge the battery voltage drops below this
threshold.
Default : 18V
Range
: battery deep discharge voltage … 28V
Resolution : 0.1V
5.2.9 Battery nominal internal resistance
Used to set the nominal battery internal resistance of the battery. When set to
automatic the system will record the next valid measurement as the nominal value.
When set to disabled no alarm related to the battery internal resistance will be
generated.
Default : Disabled
Range : 1m
Ω … 300mΩ, Disabled, Automatic
Resolution : 1m
Ω
5.2.10 Battery maximal internal resistance variation
Combined with the nominal internal resistance, it defines the threshold for the
ALARM_BATTERY_RI_TOO_HIGH.
Default : 200%
Range
: 20% … 300%
Resolution : 1%
5.2.11 Battery maximum temperature
An optional external temperature sensor ( P/N: WNTC-2MT ) is required. Used to set
the maximum temperature at which the battery can operate safely. If the measured
temperature exceeds the set value, an alarm is generated and the battery charging
is stopped until the return under normal temperature level.
Default : 50°C
Range :
30°C … 80°C
Resolution : 1°C
5.2.12 Battery minimum temperature
An optional external temperature sensor ( P/N: WNTC-2MT ) is required. Used to set
the minimum temperature at which the battery can operate safely. If the measured
temperature is lower than the set value, an alarm is generated and the battery
charging is stopped until the return under normal temperature level.
Default : -10°C
Range : -2
0°C … 0°C
Resolution : 1°C
5.2.13 Battery lifetime
Used to set the expected battery lifetime. Once the battery operating time exceeds
the set value an alarm is generated.
Default : 100kh
Range :
1kh … 200kh
Resolution : 1kh
