NORMAL OPERATION
__10,
OUT=100%VA
BATT=100%Ah
5=ON
In the basic menu the upper line presents a signaling message to describe the present status while the lower line
indicates model, apparent power measurement by percentage output by the inverter or bypass line, charging
status of the battery or time expected for duration of battery.
The viewer permits display of a single phrase at a time, hence a priority is established according to which the
most important message is displayed, while other information is entrusted to the interpretation of the internal
codes.
Under all operating conditions, after two minutes from the last command with the keys, the viewer returns to
BASIC MENU in which are presented the signaling messages for operating status.
NORMAL OPERATION:
__10:
Example of identifying initials of the type of unit with 10kVA rated power.
OUT = 100%VA
:
Example of indication of the percentage of power absorbed by the load at output when the inverter is operating.
The initials “OUT” change to “BY” when the load is not powered by the inverter but by the mains through the
bypass line.
All the indication “OUT=100%VA ” changes to “OUT=SWMB” when load is powered through line of maintenance
bypass switch, hence it is not possible to supply measurement of the output load current.
The value 100%VA supplied in the example is taken from the measurement of the output current. The number
indicates the output current with the value relative to the absolute rated value and the value indicated is the
greater of (effective current) or (peak current).
BATT=100%Ah
:
Example of indication of present status of battery recharge percentage.
The value 100%Ah is taken from
measurement of the charging current and the time elapsed in recharging.
The number indicates the percentage of recharge based on the information of the capacity of the connected
battery and the amount of charge used during battery operation. The system remains automatically on quick
charge for the entire time necessary to supply the battery with the quantity of charge lost during discharge.
The indication “%Ah” changes to “min.” during operation in absence of mains power supply or with battery
discharged. In this case the numerical value refers to the remaining minutes of operation calculated on the basis
of the current delivered by the battery and the charge status thereof.
NOTE!
The autonomy indicated is calculated on the basis of measurement of the discharge current at that moment, the
value memorized for the capacity of the connected battery and the value memorized for the percentage of
charge preceding the discharge. The autonomy value shown is always approximate because of the large
number of factors involved.
If large differences are noted between the expected value and the real time of a discharge with steady load,
check the memorized battery data and its status.
5=0N
:
Example of the indication for sound alarm enablement status: in case of exclusion, the indication changes to
“5=OFF”.
