INIT (initialisation)
An indirect mode that occurs after the hardware is initiated based on the start-
up parameters or when returning from EMERGENCY mode.
NORMAL (networked)
For the NORMAL mode, the power supply unit must be started logically (in
interface). In addition, the mains must comply with the network criteria (appropriate
voltage and frequency). The unit can then feed power from the mains to the output
via the inverter circuit. In this mode, the batteries are being charged.
HIBRID (mixed)
In HIBRID, the power supply unit feeds power from the mains to the output,
partially using the power collected in the batteries.
BACKUP (battery)
If the mains or BYPASS in ECO mode do not comply with the power supply
criteria, the unit switches to BACKUP mode (battery-based). In BACKUP, the inverter
feeds power to the battery outputs.
ECO (economical)
ECO mode can be manually forced by the user by setting the flag in the
interface (KONROLA 2/4; ECO). With the ECO flag, the NORMAL or HIBRID modes
do not operate. To switch to ECO, the network criteria must be maintained for mains
and BYPASS line. Incorrect parameters will cause the unit to switch to BACKUP.
With ECO flag on, the unit behaves similarly to OFF-LINE units. In ECO, the outputs
are fed from the BYPASS or batteries (BACKUP). Internal blocks do not participate in
power processing and entire unit is more efficient.
STOP
In STOP, the power supply unit is turned off logically (in interface) and there is
no current in the mains that would comply with the network criteria. It is an indirect
mode occurring when switching from BYPASS and EMERGENCY.
SUSPENDED
The power supply unit is turned off logically (in the interface) and the mains
comply with the network criteria. Battery preservation is active. Once switched from
STANDBY to SUSPENDED, the battery level is verified. If the level is below a limit
(KONFIGURACJA 3/5; Poj. z STB.), the unit remains in that mode until the required
minimum level has been reached.
STANDBY
STANDBY is switched only from the BACKUP mode when the batteries are
discharged or the mode is forced in the user interface (KONTROLA 2/4; UPS->STB).
The mode is switched after a predefined period (KONFIGURACJA 3/5; Opoz.STB).
The power supply remains in that mode if there is no current in the mains that would
comply with the network criteria, while the unit is turned on logically.
Once turned off logically, the unit switches to STOP or SUSPENDED.
BYPASS
BYPASS is switched when the unit is overloaded or the mode is forced in the
user interface (KONTROLA 3/4; UPS->BYPASS).
Outputs are then fed with power from the BYPASS line.
