7.6 Battery supervision
For systems with symmetry cables supplied:
Set number of battery strings according to number of battery strings in the system. The settings are to be
made in the control unit via a PC with PowCom installed or directly in the controller (if symmetry failure is
indicated).
The symmetry fault alarm is to be simulated by pulling out one symmetry cable from battery string. Measure
that setting to make sure that it is in accordance with battery manufacturer recommendations.
For systems with temp. probe cable supplied:
The temperature compensation is factory pre-set. Check that the temp. probe is activated and verify that
the compensation level is according to the battery manufacturers requirements. (If no compensation level is
available from the battery manufacture, Power One recommends it to be set to 0,5V).
7.7 Battery test
The settings should be made according to the battery manufacturer requirements, but as a rule of thumb
the following settings can be used for standard VR lead batteries:
No. of test pr. year = 2
U3 Test = 1,9 V/cell
End voltage b.test = 1,94V/cell
Batt. test time = 40% of expected backup time
Ah limit for test = 40% of nominal battery capacity
Parameters to be set/adjusted from the controller (Battery test menu) or "Supervision - Set parameters”
menu in PowCom.
