Code 07
(TWIN PRO2, TWIN/3 PRO2)
. ECO mode frequency
range.
Fig. 36.
Parameter 2 setting: The low frequency threshold in
ECO mode. The regulation range is between –5 and –10
% of the nominal frequency.
–
setting range from 46 to 49, for 50 Hz nominal .
–
setting range from 56 to 58, for 60 Hz nominal.
The preset factory figures are 48 / 58 Hz, for 50 and
60Hz respectively.
Parameter 3 setting: The high frequency threshold in
ECO mode. The regulation range is b5 and +10
% of the nominal frequency.
–
setting range from 51 to 54, for 50 Hz nominal .
–
setting range from 62 to 64, for 60 Hz nominal.
The preset factory figures are 52 / 62 Hz, for 50 and
60Hz respectively.

Code 08
(TWIN PRO2, TWIN/3 PRO2)
. Bypass mode set-
ting.
Fig. 37.
Parameter 2 setting.
–
OPN. Bypass allowed. When selecting this op-
tion, the UPS will operate on bypass mode, but
depending on the bypass setting, if it is enable or
disable (parameter 3).
–
FBD. When selecting this option, it is not allowed the
bypass mode operating under no circumstances.
Parameter 3 setting.:
–
ENA. Bypass enable. When selecting this option,
the bypass mode is enabled.
–
DIS. Bypass disabled. When selecting this option,
the automatic bypass is allowed but not the manual
bypass shifting.
Bypass shifting is understood as that one that the
end-users make it over the own UPS. I.e.: when
pressing the OFF key at the front of the equipment
when it is on normal mode, then the load is shifted
to the static bypass.

Code 09
(TWIN PRO2, TWIN/3 PRO2)
. Maximum battery
discharge time setting.
Fig. 38.
Parameter 3 setting:
–
000 ~ 999. It states the maximum back up time. The
UPS will be automatically shutdown once the time
is exceeded. The preset factory figure is 990 min-
utes [16,5 h].
–
DIS. It disables the maximum battery discharge
time of the batteries, so the back up time will de-
pend on the capacity of themselves.

(TWIN PRO2)
. Reserved.

Code 10
(TWIN/3 PRO2)
. Programmable output setting
Fig. 40.
Parameter 3 setting: Set the programmable output. It
is allowed to select one of the following three options:
–
ON: the programmable output is activated perma-
nently.
–
OFF: the programmable output is deactivated. Nev-
ertheless, if the UPS is re-start up, this setting will
change automatically to “ATO” selection.
–
ATO: the programmable output is automatically
activated or deactivated, depending on the status
of the battery or load. The programmable output
will be shutdown either when the battery voltage
is lower than the entered value or the shutdown is
done. When the input mains is restored, the output
