40 batteries UPS: Vb_min=400 Vb_ch=543 Vb_max=555
Adjustment: 2-/3+ , 5-/6+ 7=-,8=+
Vb_min (end discharge voltage) =374-450V
Vb_ch (maintenance voltage) = 500-566
Vb_max (charge voltage) = 542-566V
The checking system uses data concerning the capacity and type of battery for:
-
automatic check by the inverter of the efficiency of the battery;
- calculation of estimate of residual autonomy time;
- calculation of levels of battery voltage to activate the pre-alarm and afterwards the shut-down;
Key menu 3 5 4: PREALARM CUSTOMIZING
(306Vmin, 345Vp) Prealarm 5 min.
ADJUSTMENT: 7=-, 8=+
Vmin= minimum voltage of the battery
Vp= voltage of the discharge pre-alarm ( these two values of voltage Vmin and Vp aren't fixed
values, but are a function of battery discharging
Vp= Vmin+5V+10*(current of the battery [A]/capacity of the battery [Ah])
With keys 7 and 8 it is possible to decrease or increase the time required to activate the pre-alarm before the
system lock itself due to the complete discharge of the battery. Variations of a minute are possible within a field
ranging from 2 to 254 minutes. The pre-alarm signal activates itself when the estimated remaining time is less
than the value set for the pre-alarm or when the battery voltage is lower than the value Vp of the pre-alarm
voltage.
It is important to allow a broad safety margin when using the pre-alarm function, since the value of autonomy
required cannot foresee possible increases in absorption for the output load, and cannot take into consideration
unexpected and unforeseen faults in the battery, such as, for example faulty single elements or connections.
Key menu 3 5 6: AUTO-OFF CUSTOMIZING “VA”
AUTOMATIC SWITCH-OFF WHEN OUTPUT < 10%VA
ADJUSTMENT:
(5=Toff, 6=Ton)
7=-, 8=+
Keys 7 and 8 are used to reduce or increase the percentage of output load for the AUTO-OFF function.
Increments of adjustment are by 1 % in the range from 0 to 99%.
When the AUTO OFF alarm is present , if the input main line voltage is present and the battery charge is lower
than 60% there is only the display of:
BYPASS FOR OUTPUT VA < AUTO-OFF VALUE
_30,
OUT=100%VA BATT= 50%Ah 5=ON
The system does not start the "off procedure" because it waits to charge the battery over 60%.
When the alarm is present, if the input main line voltage is present and the battery charge is higher than 60%, or
if the system is in battery operation, there is the display of:
BYPASS FOR OUTPUT VA < AUTO-OFF VALUE
_30, OUT=100%VA
0FF: 4 min, 5=ON
Moreover the "prealarm low battery" remote alarm contact switches on alarm position.
In the case of status displayed above, the system continue to operate for the next 4 minutes, after those it
switches on bypass.
