9.- OPERATION: SINGLE UPS
This is a True On Line Double Conversion UPS and it is designed to offer clean, bump-less and highest quality power to your
computer related equipments protecting also your valuable data. Power delivered by UPS is 100% sine wave as main line.
According to AC Line status the UPS may operate in following modes:
ONLINE NORMAL Mode
When UPS is turned off by selecting ON push button in front panel and AC Line is normal it enters into ONLINE NORMAL mode. Under
this mode UPS Inverter powers outputs and the energy is taken from DC voltage coming from AC/DC converter. Batteries are charged
by AC Line if required.
BATTERY Mode (Also known Inverter Mode)
Under ONLINE NORMAL mode when UPS detects a problem in AC input Line or black out it enters in battery mode. Under this mode
UPS takes energy from its batteries to power outputs. There are no transfers neither micro-cuts on UPS outputs as inverter was
already working, the only difference is that energy for outputs is now coming from batteries. Transfer time is actually Zero (0 ms).
UPS also can enter in battery mode when it is turned on without an acceptable AC input.
ECO Mode
There is an energy saving function that makes UPS to power its outputs with AC Line directly. If under this mode, UPS detects AC
input is out of acceptable range it enters into Normal Online mode.
If an AC failure occurs under ECO mode the UPS’s inverter starts working draining energy from batteries. There is a transfer time of 4
ms typical. This mode is configured and activated from LCD panel. There is specific input voltage range and input frequency range to
configure for ECO mode.
BYPASS Mode
Under BYPASS mode, UPS outputs are powered by AC Line. UPS is out of the circuit. This mode can be caused by operator when
OFF button is activated, but it may also happen automatically by UPS malfunction or overload detected at UPS outputs. If external
(optional) BYPASS module is installed, UPS goes to BYPASS mode when protection cover of the bypass switch is removed.
FREQUENCY CONVERSION Function
This UPS offers a very sophisticated function named frequency conversion (CF) that allows UPS to generate power output at
determined frequency value (50Hz or 60Hz) no matter input frequency value. UPs will be able to generate output at 50Hz even input
source is at 60Hz or generate 60Hz even if connected to 50Hz source.
This function can be configured and activated by LCD. Revise configuration section of this manual.
IMPORTANT NOTES:
1.- Under CF mode, UPS will disable BYPASS mode. Since UPS has been configured to generate output with frequency value different
to input frequency, BYPASS mode is disable to avoid a not acceptable frequency value at output.
2.- When CF function is activated, maximum power output is de-rated to 60% of maximum nominal capacity. For example, for a
10KVA (8KW) model, when CF is activated maximum output is decreased to 6KVA (4.8KW).
WARNING Mode
Under some situations UPS reports an alarm or warning message in the LCD and buzzer will be activated with intermittent beep.
Usually UPS keep working in online mode.
FAULT Mode
When important problem is detected inside or outside the UPS, it goes to fault mode reporting an error message on LCD and activating buzzer with a
continuous beep. Under this mode UPS usually goes to BYPASS mode. Fault LED turns on in red color when fault mode is adopted.
