2.2 On/Off/Test/Silence Button
The On/Off/Test/Silence Button has four functions:
1.
When the UPS is off and AC power is present, press this button for
more than 3 seconds to turn on the UPS. The UPS can be turned on
even when AC power is not present.
2.
When the UPS is on, press this button for more than 3 seconds to
turn off the UPS and output power.
3.
When the UPS is operating in “BACKUP” mode, you can silence the
alarm by quickly pressing the power button. (This function is disabled
when the UPS has a “LOW BATTERY” or “OVERLOOAD” condition).
4.
Quickly press the button while the UPS is under “AC” mode, and the
UPS will perform an automatic self-test procedure.
* “No load shut down” function: As a battery saving feature, the UPS will
automatically turn off if none of the connected equipment is operating
while the UPS is in back-up mode. Once normal utility power returns, the
unit will wake up automatically. You can disable the “No load shut
down” function by pressing the power button until you hear two beeps.
2.3 Audible Alarm
1. BACKUP mode
:
When the UPS is working under “Battery” mode, the
UPS will emit an audible alarm. The alarm beeps every 2 seconds.
The alarm stops when the UPS returns to ”AC” mode.
2. LOW BATTERY
:
In the “Battery” mode, the alarm will begin to beep
more rapidly when the battery energy becomes low. This means that
the UPS will soon shut down from battery exhaustion, until the unit can
return to ”AC” mode and charge the batteries again.
3. OVER LOAD
:
When the UPS is working under overload condition (the
connected equipment exceeds the maximum rated capacity), the UPS
will emit a continuous alarm. In order to protect the unit and the
equipment, the UPS may automatically turn off. Please disconnect
nonessential devices from the UPS to eliminate the overload alarm.
