WARNING
:
In this condition, a power outage will lead to a loss supply to the connected load. The UPS will
behave in different ways depending on the operational status it is in.
Bypass command when running in ON LINE mode: the system is switched to bypass and the inverter
is shut down.
NOTE:
if bypass is not available this command is not executed.
Bypass command when running in ECO MODE: the UPS is normally on bypass. If the bypass command is
activated, the output relay is opened and the UPS is no longer able to switch into battery status. The system
is switched onto bypass.
Bypass command from Stand-by off mode: the load is supplied from bypass and the system is switched
onto bypass. This function can be useful for lamp testing in emergency lighting systems.
Bypass command from frequency converter mode: the command is disabled. When working in frequency
converter mode any operation with the bypass is not possible.
Battery Test command
Battery commands page
SE UPS are equipped with a built-in battery test function. This function forces the UPS to work from battery and
monitors the battery voltage under load to check if the battery is healthy.
NOTE:
the UPS switches to battery just for the short time needed to execute the battery test and only when the
main supply is present as backup, therefore the battery charge level and the load safety are not compromised.
The battery test is activated only when the UPS is ON, the SWOUT is closed and the battery charge level is ≥
90%. Otherwise, the test will not be executed immediately, however the command remains active and the battery
test will start as soon as these conditions are met.
Press the “Battery test” icon to execute the battery test. A confirmation is required. The progress bar will show the
progress of the battery test.
Battery Charger On command
Tap the “Batt. charger On” command to turn on the battery charger when the UPS is in stand-by mode to enter
STAND-BY WITH BC ON mode (a confirmation is required) In these conditions the UPS output is not powered but
the battery is under charge.
Alarm temporary suppression
If the system buzzer is beeping due to a prolonged fault state, the user can silence the alarm by pressing
the Buzzer toggle button.
For further information refer to the “buzzer” paragraph in the “user interface” Chapter.
