6.2.3. Line mode.
The LCD panel on line mode is shown in figure 14. The infor-
mation about mains, battery, UPS output and load will be dis-
played. The UPS operating code is «2».
In the same figure that the «INVERTER» stage is displayed
(frame with INVERTER inscription inside) and active, it means
that the inverter is supplying the used power by the load/s and at
the same time the batteries are being charged.
If the output is overloaded, the percentage of load and the
acoustic alarm will be triggered activated with two beeps every
second. It is needed to shutdown the noncritical loads in order to
decrease the percentage of load below the 90% of its nominal
capacity.

6.2.4. Battery mode / Battery test mode.
The LCD panel on battery mode is shown on figure 15. The
information about mains, battery, UPS output and load will be
displayed. The UPS operating code is «3».
In the same figure that the «INVERTER» stage is displayed
(frame with INVERTER inscription inside) and active, it means
that the inverter is supplying the used power by the load/s, but
the batteries are not being charged due to the lack of mains or
wrong mains.
When the UPS works on battery mode, the acoustic alarm will
be triggered every four seconds. If the button «ON» of the front
panel is pressed for more than 1 second, the alarm will be si-
lenced. Press the button «ON» for more than 1 second again, in
order to re-activate the acoustic alarm function.
If the UPS is working on battery mode and the input line voltage
is higher than the specific range the of the equipment, there will
be displayed a letter «H» as an alarm mode. Meanwhile if the
input line voltage is lower than the specific range of the equip-
ment, there will be displayed a letter «L» as an alarm too. In case
there is an input mains failure, any letter will not be displayed and
voltage and frequency meters will be shown as zero.
The same screen of figure 16 will be shown for battery test mode
and the letters «H» or «L» will be displayed during the test, if the
input is higher or lower than the specific range of the equipment.
The operating mode code of the UPS is «3» for battery mode and
«4» for battery test mode.

6.2.5. Wrong mode.
It is considered as wrong mode any of the fault or warning codes
shown in table 6. Also a warning word can be displayed in the
LCD panel, i.e. «SHORT», in order to identify that the equipment
or load are short-circuited and therefore the UPS is on inverter
fault mode. See table 7 of chapter 7.
6.2.6. ECO mode (Economy).
It is also known as high efficiency mode (HE). The UPS oper-
ating code of ECO mode is «5».
On ECO operating mode, the load is supplied from mains directly
through the internal filter, meanwhile the voltage and frequency
are inside the preset range, so a high efficiency is achieved.
When mains is wrong or there is a fault in the energy, the UPS
transfers to battery mode and the load will be supplied from bat-
teries till the normal conditions of the electrical mains are re-
stored.
The ECO mode can be activated by means of the screen, or
software (Winpower, ...).
It has to be considered that the transfer time of ECO mode to bat-
tery mode is less than 10 ms. But for some sensitive loads, it is still
too much, so act in consequence for each particular case when
activating the ECO mode.
6.2.7. Converter mode.
The UPS operating code on Converter mode is «6». On this op-
erating mode, the UPS works with a fix output frequency (50 Hz
or 60 Hz).
When mains is wrong or there is a blackout, the UPS will transfer
to battery mode and the load will be supplied from batteries, till
the normal conditions of the electrical mains are restored.
The Converter mode can be activated by means of the setting
screen, or software (Winpower, ...).
It has to be considered that on this operating mode, the power
rate of the equipment is derated up to the 60 % of the nominal.
