UPS CHARACTERISTICS (Smart-UPS and Matrix UPS, Cont.)
Setting Description
Sensitivity
Sensitivity of the UPS to power line fluctuation. Set this
value according to the type and magnitude of expected
fluctuation and the susceptibility of the load. Values range
from high to low sensitivity. Use lower sensitivity settings
when running from a less stable power source, e.g., an
inexpensive fuel-powered generator, when you have deter-
mined that the connected devices can handle the instability.
Shutdown
Delay
Time interval between issuance of a UPS turn off command
and actual shutdown of the load. Since the UPS notifies the
computer of the impending shutdown, Shutdown Delay
allows for graceful turn off.
Return Delay
Time interval after which the UPS turns on after restoration
of utility power. Use return delay to prevent branch circuit
overloads.
UPS Self Test
Time intervals between UPS battery self-tests.
Audible Alarm
Function of the UPS audible alarm.
Low Battery
Duration
Time interval between low-battery warning and shutdown of
the UPS. Select from values between 2 and 10 minutes.
Return
Battery
Capacity
Battery capacity desired for UPS restart after a power
outage. Select from values between 0% and 90%. At 0%,
the UPS will restart as soon as utility line power returns to
normal. With other settings, the UPS will charge the
batteries to the specified level prior to restart.
