EVER POWERLINE RT PLUS UPS Operating Manual
BYPASS mode.
The BYPASS mode is activated when the UPS unit is overloaded (the
option "go to BYPASS if overloaded" option must be activated - the
option can be activated in PowerSoft) or when an overriding command
is given from the user interface (ENTER and ESC buttons are pressed
simultaneously). To deactivate the BYPASS mode (forced bypass),
press the ON button on the front panel. The UPS may also operate in
the BYPASS mode if it was not started logically (with the front panel
button) and the mains parameters satisfy the mains correctness
criteria (the option 008 - "Enable" must be activated). If the UPS has
entered BYPASS mode due to overload, it will periodically check the
load. When this value is back to standard levels, the UPS will restart
the inverter. In the BYPASS mode the UPS unit does not protect its
receivers from power losses. The voltage from the input line is
directed to the unit's output through an internal filter.
The UPS generates a sound signal every 20 s in the BYPASS mode.
The BYPASS mode cannot be activated if the INVERTER mode is on.
STANDBY mode.
The UPS unit is logically switched off, the main lines meet correctness
criteria for the mains. The battery-saving functions and mechanisms
are active.
The LCD panel shows information on the battery charge level and the
mains parameters. The UPS unit is not supplying power to the output
(receivers are not powered).
ECO mode.
A power saving, high efficiency mode. For the UPS unit to operate in
ECO mode, the mains correctness criteria must be in specific
tolerance (+/- 10% or +/- 15%) configured in the unit's settings menu
(menu 003). The receivers are supplied from the mains through an
internal filter. UPS energy blocks do not take part in processing
energy and therefore this mode has high efficiency. In case of an
interruption in the mains or if power parameters of the mains exceed
permissible range, the UPS unit switches to battery mode (the device
is powered until the battery is discharged or proper power is restored
from the mains).
The function may be activated via the LCD display (settings menu
003). Note that the UPS switching time between ECO and battery
modes is about 10 ms, which may be crucial for some sensitive
receivers.
INVERTER mode (frequency converter).
In the inverter mode, the UPS unit may freely operate with the output
frequency of 50 Hz or 60 Hz. In case of an interruption in the mains or
if the power parameters of the mains exceed permissible range, the
UPS unit switches to battery mode and the devices connected to the
UPS are continuously powered, the until battery is discharged or
proper power is restored from the mains. The icons flashes when
