System controller setup verification

The process described in this section lets you check the controller settings. This verification
procedure is available for software versions beginning from 050106.
7.2.1 ACCESS
Press ESCAPE key and hold it for 3S. Using ARROW UP/DOWN key, select GENERAL (8) and
press ENTER. Screen 1 is presented.
7.2.1.1 SCREEN 1
a) ACV: nominal value of the input/output AC voltage (220 for 2x32 batteries ; 110 for 2x16 batteries).
b) ALM: input AC voltage alarm HIGH/LOW
c) TEMP.ALARM: high temperature limit for external thermosensor
d) MODULES: QUANTITY/REDUNDANCY – 07/02 in the screen means that 7 modules are
presented in the system, 2 modules are reserve (full load is 10KVA*(7-2)=50KVA/40KW)
e) C.LIM.=off (VALUE)- battery current limit function is de-activated (off) or max. battery current value
in Amps. In C.LIM is activated, the system must be equipped with optional battery current sensor.
f) T.C.=2.0mV – negative temperature coefficient of the battery DC voltage in mV per ºC per battery
cell. Nominal temperature is 25ºC. For DC nominal voltage 432V , temperature 35ºC, 32 batteries
of 6 cells, T.C.=2mV, the voltage is 432- 2*6*32*(35-25)~=428V. NOTE. For most applications T.C.
must be 0 (off).
g) DCV: DC nominal voltage for both positive and negative battery sets. For 32 batteries in the set
DCV=432V, for 16 batteries 216V.
h) DCV ...ALM: DC voltage alarms HIGH/LOW/SHUTDOWN. SHUTDOWN alarm is DC voltage value
when the unit is stopped due to battery discharge.
i) BATT....TEST: PERIOD IN WEEKS/MAX.DURATION IN HOURS/ALARM VOLTAGE/CHARGER
DERATED VOLTAGE. In the screen: the test is performed automatically once per 4 weeks, max.
test duration is 5 Hours, if battery voltage drops below 360V alarm Battery Low is given, the
chargers of the modules continue to supply voltage 352V to prevent shutdown if battery is faulty.
j) CAP: CAPACITY in Amp-Hours. Used to calculate estimated back-up time of the system and
battery test duration.
