10.1.2 Battery Data

Protect 5.31/xxx-480-220-120 10 kVA - 120 kVA
Depending on the system configuration, different battery parameters
can be set in the "SERVICE / BATTERY VALUES" menu. The
parameters for the individual battery tests are also set in this menu.
Please refer to the data sheets of the battery manufacturer for the
individual values to be set.
The following abbreviations are used in the menus:
Tri = Trickle charging
Equ = Equalising charging
Cha = Charging
EPS = Charging with emergency power supply operation
Sta = Start-up charging
The parameters can be set within restricted ranges. This range
depends on the unit type. The unit type can be displayed on the DOU
in the "Information" menu.
The max. values for the number of cells and the voltages can differ
from the values mentioned above because a max. total battery
voltage must not be exceeded. Parameters "Final disch. voltage/cell",
"Max. disch. time" and "Disch. current" refer to the battery tests.
The "Disch. time" depends on the battery test.

The Battery Time of Discharge parameters can be set using the
"SERVICE / BTD VALUES" menu.
Please refer to the data sheets of the battery manufacturer for the
individual values to be set.
Using the battery table, the discharge powers or discharge currents of
two different standby times are determined for a final discharge
voltage of approx. 80% of the nominal battery voltage (1.6 V/cell for
lead-acid batteries) depending on the unit type. To do this, it is best to
select the following values:
One pair of values lies in the range of the nominal standby time of the
system, and another at a standby time which is three times the
nominal standby time.
