Operation
Eaton 9130 700/3000 VA UPS User’s Guide 164201718—Rev 7 www.eaton.com/powerquality 35
You can prohibit Bypass (”Never”) or always allow Bypass with no specification checking (“Always”). For
“Always on UPS Fault,” transfer to Bypass is always made on UPS fault; otherwise, operation proceeds as with
the default setting.
Synchronization Window. The
UPS tries to synchronize with Bypass when the Bypass frequency is less than
the value set for the “Synchronization Window” setting. When the Bypass frequency is more than the set
value, the UPS goes to nominal frequency. On Bypass the synchronization window is 5 Hz. If synchronization
is disabled (”Sync Disabled”), the
UPS will synchronize only when operating on Bypass.
Unsynchronized Transfers. The default allows an unsynchronized transfer to Bypass. You can configure the
setting to not allow such transfers. This setting can be overruled by the “Qualify Bypass” setting.
Configuring Load Segments
Load segments are sets of receptacles that can be controlled by power management software or through the
display, providing an orderly shutdown and startup of your equipment. For example, during a power outage,
you can keep key pieces of equipment running while you turn off other equipment. This feature allows you to
save battery power.
Each UPS has two configurable load segments:
l
Load Segment 1: Upper outlets and higher rated outlets if available.
l
Load Segment 2: Lower outlets
See “Rear Panels” on page 69 for load segments for each UPS model.
To control the load segments with
power management software, see your power management software
manual for details (refer to the Software Suite CD or www.eaton.com/powerquality for the latest information).
To control the load segments through the display:
1. Press any button to activate the menu options, then select CONTROL and LOAD SEGMENTS.
2. Set the desired load segment ON or OFF, and ENTER to confirm.
3. Set the other load segment if applicable.
To set the restart and shutdown delay times for
each load segment:
1. Press any button to activate the menu options, then select SETTINGS, USER SETTINGS and AUTOMATIC
ST
ART DELAY.
2. Set the restart delay for one load segment, and ENTER to confirm.
3. Set the other load segment if applicable.
4. Select AUTOMATIC ON BATTERY SHUTDOWN.
5. Set the shutdown delay for one load segment, and ENTER to confirm.
6. Set the other load segment if applicable.
NOTE Load segment On/Off commands issued through the Control menu overrule the
user settings for load segments.
