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.

Figure 288: General (Screen 2)
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.
