1.1.18
On - line - factory setting -
Load is always powered by the inverter, in the event of an input mains failure the load
continues to be powered from the inverter using the energy stored by the batteries.
On – line:
The load is always powered by the inverter, with stabilized voltage and frequency, using
the energy from the mains power supply (INPUT). If there is a fault in the INPUT, the
UPS will switch to the batteries in zero time and the batteries will supply energy to the
inverter to keep the load powered for the backup time of the batteries. When the INPUT
is restored the batteries will be automatically recharged by the rectifier.
1.1.19
Standby-on / Smart active
Load is powered from the mains, in the event of an input mains failure the load is powered
from the inverter using the energy stored by the batteries.
In
Standby On
or
smart active,
the load is powered from the bypass line (if the mains power
supply is in the range); if there is a fault on the mains power supply the load switches
automatically onto the inverter, powered by the battery
Standby On:
The switch from inverter to bypass line may be immediate (time set = 0) or delayed (up to
180 minutes). For the switch to take place, the bypass line must be in the range for the
delay time set. In
Standby On
mode, the rectifier remains powered and keeps the
batteries charged. If the bypass line voltage or frequencies are out of the range, the load is
automatically transferred onto the inverter output. With
Standby On
operation, the losses
of the system can be reduced, leading to considerable saving. Before using this function
it must be guaranteed that, in the event of a mains outage, the load powered can tolerate
an interruption of the power supply of about 2-5 ms, and that it can tolerate any mains
disturbances.
This operating mode is normally used for loads that are not much sensitive.
While operating in this mode, the letter
N
will be displayed on the second line of the
BASIC MENU, near the UPS model.
Smart Active
:
The UPS automatically activates
On-Line
or
Standby-On
operation according to the
quality of the power supply (see the “PERSONALIZ. SMART ACTIVE OPERATION”
menu). When Smart Active mode is enabled, the mains is monitored for a few minutes, at
the end of which if voltage is in the acceptable range, the load is transferred to the bypass
line. If mains is out of the range the load remains powered by the inverter and the bypass
line is monitored for about one hour before retransfer the load to bypass if no
disturbances occurred. If any, the cycle of monitoring the line for one hour restart. The
main advantage of this operating mode is the efficiency, greater than 98%.
While operating in this mode
SMART A
will be displayed on the first line of the BASIC
MENU and the letter
M
will appear in the second line of the BASIC MENU, near the
UPS model.
1.1.20
Standby-off (with mains present the load is not powered)
Load is not powered, in the event of an input mains failure the load is powered from the
inverter using the energy stored by the batteries.
