UPS EVO DSP TT 11 User’s Manual
When UPS has no separate Bypass mains input, Bypass line is also fed from the mains input. Thus, if
such a device is in question, mains input shall be comprehended when the Bypass mains input is
referred in the following sections of the manual.
UPS behavior at the start-up is different from the usual operation. The UPS can only operate in Bypass
mode during start-up. So, in order for the UPS to start-up, frequency/waveform/RMS value of the
Bypass mains voltage shall be in acceptable limits and Bypass shall be enabled.
After start-up, the following applies:
Operating mode depends on the priority, Inverter, Rectifier and Bypass preferences made by the user
and mains, separate Bypass mains and battery voltages.
Priority and Inverter, Rectifier and Bypass preferences can be set by using the “COMMANDS” menu and
“EXTENDED CMNDS” submenu.
If operation in any of these modes is impossible, output voltage will not be present. In this case, loads
will not be fed, and “VSECFLR” alarm message is shown on the LCD instead of operating mode.
3.1 Bypass Mode
Devices without separate Bypass mains input, energy is drawn from the mains. In devices with separate
Bypass mains input, energy is drawn from the separate Bypass mains.
Loads are fed via static Bypass line.
Output voltage has the same amplitude, frequency and waveform as the input voltage.
Current drawn by the loads are only limited by the thermal/magnetic breakers over the energy flow
path.
Voltage, frequency and waveform of the Bypass supply shall be within their tolerance limits, and
Bypass shall be enabled for the UPS to operate in this mode.
When the upper provisions are met, the UPS works in Bypass mode in the following conditions:
During the start-up;
If the Bypass priority is selected;
If the Inverter is disabled or blocked;
In case of a prolonged Overload.
ECO Mode
You can save energy by selecting the Bypass priority. Efficiency in Bypass mode is higher than
the efficiency in Normal mode. If the Bypass priority is selected, the UPS will operate in Bypass
mode whenever the frequency/waveform/RMS value of Bypass mains voltage is within their
tolerance limits. If the Bypass voltage goes beyond these limits, the UPS switches into normal
operation.
Bypass mode does not provide perfect stability in frequency/waveform/RMS value of the
output voltage like in Normal mode. Thus, the use of this mode should be carefully
executed according to the level of protection required by the application.
Bypass mode does not provide electronic short circuit protection like in Normal mode. If
a short circuit occurs on the output during Bypass operation, the thermal/magnetic
protection will act and all loads will be de energized – load will be stopped.
Prolonged overloads may cause the thermal/magnetic protection to act. In this case, all
loads will be de energized – load output will be stopped.
