Temperature Hysteresis
The temperature value may drift when it approaches the upper or lower limit as set by the user.
Without hysteresis, when the temperature fluctuates around the set limit, it may trigger the
generation of multiple alarm notifications. The hysteresis setting defines the number of degrees
the measured value must change before the alarm clears. For example, if the temperature upper
limit is set to 60 degrees and the hysteresis is set at 2 degrees, then the alarm will trigger at 60
degrees, but will not clear until the temperature drops below 58 degrees. The default hysteresis
setting is 0 degrees Celsius.(0~20)
Over Load Set Point
Set the upper limit of UPS output load. When UPS output load exceed this limit , USHA will take
action that is specified in the UPS Shutdown menu. (0~150)
UPS Control
For more detail on the shutdown process, refer to the user manual.
UPS Shutdown Delay
The delay in seconds the UPS remains on after being told to sleep. The UPS shutdown delay time
will be count-down synchronize to the shutdown delay time set in the Shutdown Program in all
connected clients. To avoid improper shutdown of the clients, the UPS shutdown delay time set in
USHA should always be greater than the shutdown delay time set in the Shutdown Program.
UPS Sleep Time
The time in minutes for the UPS to go to sleep when instructed. When in Sleep mode, the UPS will
not provide output power regardless of the input line state. Once the specified time has elapsed,
output power will be restored.
Turn Off UPS
Setting Turn off UPS causes the UPS to turn off after a delay of UPS Shutdown Delay time. The
output power can be restored by the Turn on UPS/Cancel UPS Shutdown option.
UPS Sleep
Setting UPS Sleep causes the UPS to go to sleep for the time specified by UPS Sleep Time after
the delay time as configured in UPS Shutdown Delay. When in sleep mode, the UPS will not
provide output power. Once the specified time has elapsed, UPS will provide output power.
Turn On UPS/Cancel UPS Shutdown
Setting Turn On UPS/Cancel UPS Shutdown causes the UPS to cancel any on-going shutdown
process. If the UPS has already shutdown, then it cancels the sleep command and brings back the
output power.
