Configuration
NOTE: Your UPS may
not support all of the
configuration options
listed in this document.
Temperature Threshold:
The maximum internal
UPS temperature
allowed before triggering
a
UPS over temperature
alarm.
Overload Threshold:
The maximum percent
load allowed before
triggering a UPS
overload alarm.
Power Margin:
The maximum percent load allowed before triggering a Power Margin Exceeded
Low/High Transfer Point: (Stand-by & Line Interactive)
The transfer points determine the range of acceptable output voltage values. If the input
line voltage drops below the lower transfer point or rises above the upper transfer point,
the UPS takes corrective action either by using the booster or switching to battery power.
The proper setting of transfer points depends on the voltage tolerance of the devices
connected to the UPS. Setting the transfer points closer together will cause the UPS to
provide a more tightly controlled voltage, but may also cause the UPS to switch to battery
power more frequently, depending on the quality of your AC line power. The factory
default values are sufficient for most applications.
Battery Replacement Date:
The date on which the UPS was first commissioned or when the battery was last
replaced.
This value will be set automatically the first time ManageUPS boots up and retrieves a
valid date from a network time (NTP) server. The assumption is that the ManageUPS is
installed at about the same time the UPS is first installed and commissioned.
It is up to the user to set this date to a more accurate commissioning date and to maintain
the date when batteries are replaced in the future.
Replace Battery When:
Counts elapsed time from the value in the
Battery Replacement Date
field.
Low Battery Alarm Duration:
Triggers the UPS Low Battery alarm when estimated minutes remaining -- as computed
by the UPS, or limited by the
Authorized Autonomy
setting -- reaches this value.
