batteries of 6 cells, T.C.=2 mV, the voltage is 432- 2*6*32*(35-25)~=428 V. 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=432 V, for 16 batteries 216 V.
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 360 V alarm Battery Low is produced, and
the chargers for the modules continue to supply a voltage of 352 V 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.

A description of the various system parameters shown in screen 2 are listed below.
a. CURRSHARE RST: displays the status of the current sharing—either enabled or disabled (EN or
DIS).
b. #OF PHASE: FORCE 3 for 3-phase output, FORCE 1 for single-phase output or AUTO when the
mode is defined by DIP SWITCH of the modules.
c. REV: revision of the system controller (SC) software.
d. LVD BY AC FAIL: DIS (disabled) or EN (enabled). This function, if enabled, performs system
shutdown after 3 hours of ac failure to prevent deep battery discharge by low current. For most
applications, the function must be disabled.
e. MAINT: YEAR.MONTH.DAY: date of last maintenance.
f. TEMP. SENSOR: DIS or EN. External temperature sensor is disabled/ enabled. In most
applications, it must be disabled.
g. SITE: the site identification number is used in network applications.
h. CURR.SENSOR: DIS or EN. Optional battery current sensor is disabled/ enabled. In most
applications, it must be disabled.
