3. Operation
3.1 Front Panel Switches
“ON/TEST” Button:
This button controls four separate functions:
UPS System Power ON
To turn on the UPS system, press the “ON/TEST” button for
approximately one second until the UPS system beeps, then release
the button. The “ON LINE” LED will illuminate.
UPS System Self-Test
To initiate a self-test of the battery during normal on-line operation,
press this button for approximately one second until the UPS system
beeps, then release it. The UPS system will shift to battery power for
10 seconds.
Note:
All LEDs illuminate during a self-test.
Alarm Silence
To silence the UPS system’s on battery alarm, press this button and
hold it until the UPS system beeps, then release the button.
UPS System Cold Start
To use the UPS system as a stand-alone power source when AC
power is unavailable (i.e. during a blackout), press this button and
hold it until the UPS system beeps, then release the button. The
UPS system will then provide battery power to its outlets.*
* The “ON BATT” indicator light will be illuminated since the UPS system will
be operating from battery power.
“OFF” Button:
This button turns off power to the UPS system’s
outlets. Press this button and hold it until the UPS system beeps,
then release it. The battery will continue to charge and the fan will
continue to operate even when the outlets are off. To turn the UPS
system off completely, including the battery charger, unplug the UPS
system’s power cord after pressing the “OFF” switch.
3.2 Advanced Operational Settings
Economy Mode
The UPS system supports economy mode operation to reduce energy consumption and
BTU emissions. In economy mode, the UPS system operates with increased efficiency
when the quality of utility power is satisfactory to pass through to connected equipment
without double conversion.
Economy mode saves energy by suspending double conversion when incoming voltage is
within -12%/+10% of the nominal voltage setting. If the nominal voltage setting is 230V,
the UPS system will remain in economy mode while utility line voltage is between
approximately 202V and 253V. If utility line voltage falls outside this range, the UPS
system will either switch back to standard on-line, double conversion mode or it will switch
to battery backup mode, depending on the severity of the voltage deviation.
Economy mode can be enabled (or disabled) through the included PowerAlert software or
the optional WEBCARDLX internal accessory card. The UPS system's yellow “BYPASS” LED
will illuminate continuously when economy mode is enabled. Refer to the PowerAlert or
WEBCARDLX documentation for more information.
