5. Operation
5.1 Front Panel Switches
"ON/TEST" Button: This button controls 5 separate functions:
UPS System Power ON
To turn on the UPS system, press the "ON/TEST" button for approximately 1
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 1 second until the UPS system beeps, then
release it. The UPS system will transfer 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 once 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.
Troubleshooting
If the "FAULT" LED illuminates, determine the specific fault condition by
activating the error code LEDs. To activate the error code LEDs, press the
"ON/TEST" button until the UPS system beeps, then release the button. The
error code LEDs will illuminate for 5 seconds.
"OFF" Button: This button places the UPS into Bypass mode. 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. To turn the
UPS system off completely, including the battery charger, unplug the UPS
system's power cord after pressing the "OFF" switch.
5.2 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
-10%/+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 207V 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 may be enabled (or disabled) through 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.
On-line, double-conversion mode (default)
Typical line efficiency at full load: 92%
Output voltage range: ± 2% of nominal setting (200/208/220/230/240V)
Economy mode
Typical line efficiency at full load: 97%
Output voltage range: -10%/+10% of nominal setting (200/208/220/230/240V)
