BATTERY MODE
The UPS automatically runs in BATTERY mode if the Mains Voltage amplitude gets out of
security limits (in case of a black-out or overvoltage-lowvoltage): in this case, the UPS supplies
the required output power by its internal battery and by the DC/DC CONVERTER, BOOSTER and
INVERTER blocks (see figure 1).
The UPS automatically returns to function in LINE mode a few seconds after the AC input line is
recovered.
The BATTERY mode is characterized by:
•
An acoustic signal every 4 seconds indicating that the batteries are discharged. The acoustic
signal can be disconnected by pressing the ON/TEST/ALARM button.
•
The INVERTER led and BATTERY led switched ON.
•
The LOAD LEVEL and BAT. LEVEL led bars are switched on.
BYPASS MODE
In BYPASS mode (see figure 1), the AC input line is directly connected to the UPS outlets by an
AUTOMATIC BYPASS.
EVO RT uses the BYPASS mode during the start-up phase; furthermore the UPS switches
automatically to BYPASS mode in consequence of accidental overload or Inverter fault thus
protecting the supplied devices.
The BYPASS mode is characterized by:
•
The BYPASS led and LINE led switched on.
•
The LOAD LEVEL and BAT. LEVEL led bars switched on.
The UPS can be transferred in BYPASS mode even through a manual operation.
First of all one must be sure that the UPS is working properly in LINE mode. The manual
BYPASS switch is positioned on the rear side of the product (see figure 3). If this switch is in
the ON position (BYPASS), the UPS changes in BYPASS mode and indicates this condition with:
•
The BYPASS led and LINE led switched on.
•
The entire LOAD LEVEL led bar switched on, the red OVERLOAD and FAULT Leds switched on.
•
Continuous acoustic alarm.
The UPS starts working again normally when the OFF switch is in (NORMAL) position. Acoustic
alarm stops immediately and the UPS carries out an operating SELF TEST (during which the red
FAULT and OVERLOAD Leds are switched on). After a few seconds the BYPASS led is switched
off and the INVERTER led is switched on: this indicates that the UPS has started working
normally in LINE mode.
During the above mentioned operations, the devices powered by UPS will continue working
regularly
WARNING
BYPASS operations must be carried out ONLY by qualified Technical personnel
specialised and authorised by Tecnoware.
LOW BATTERY AND AUTOMATIC RESTART
In BATTERY mode, EVO RT indicates the LOW BATTERY condition whenever the battery
reaches a charge level allowing connected devices to operate for approximately one more
minute.
