MAINS MODE (NORMAL)
Connecting the UPS to the mains does not mean voltage is present on the UPS's
output sockets. The unit is only started when the switch button on the front panel is
pressed. When the UPS is switched on, a sound signal will be heard and the
message
will be displayed on the LCD. If the mains voltage is
incorrect (voltage is too low or too high, frequency is out of range), the UPS will
switch to back-up mode, which will be indicated by the message
(BACK-UP
MODE) and a sound signal will be heard every 10 seconds.
When the UPS unit is in the mains mode, the power in the output sockets is filtered
and, if needed, raised or lowered by the AVR system. The LCD panel displays the
load, the battery level, the mains mode icon and the values of the input and output
voltage.
BACK-UP MODE (BATTERY OPERATION)
When the UPS is in the normal (mains) mode and the voltage drops or its parameters
deteriorate (voltage or frequency parameters are out of range), the UPS will
automatically switch to back-up mode. This is signaled by an intermittent sound
signal (every 10 seconds) and an activated icon
(MAINS MODE icon will
disappear).
If the battery charge level is low, an alarm sound is generated every second. Once
the battery is discharged, the UPS will switch off and the receivers will not be
supplied with power. When the supply voltage is back, the UPS will restart.
When the UPS is in back-up (battery) mode and there are no receivers connected or
power consumption is below the threshold value (40 W in the model EASYLINE 650
and 50 W model EASYLINE 850), the UPS will automatically switch off after 60
minutes in order to protect the battery before over-discharge them. This function can
not be deactivated.
STANDBY MODE
The UPS will switch to STANDBY mode when the battery is completely discharged or
when this mode is initiated by the managing software. The UPS will wait until the
mains parameters are correct again and will then switch back to the mains mode.
