Result of last Selftest:
None – no recent selftest
OK – most recent selftest was satisfactory
Unavail – unavailable
Can’t Tst – UPS could not perform the test at the time.
Failed – battery condition has deteriorated below a
reliable level, the battery should be replaced.
Setup
n Transfer – these first three parameters control when the UPS
switches to battery.
Low Xfer (Lower transfer voltage) – the output voltage at
which the UPS switches transformer taps or onto battery.
High Xfer (High transfer voltage) – the output voltage at
which the UPS switches transformer taps or onto battery.
(If you notice that the input voltage is generally close to one end
of the lower/upper voltage window, it may be necessary, depend-
ing on the load’s voltage requirements, to recenter the window by
changing the lower and/or upper transfer voltages)
Sensitivity – sudden, small changes in input voltage will cause
the UPS to briefly run on battery.
(If you notice, or the event log indicates, that the UPS transfers to
battery frequently, it may be necessary, depending on the load’s
voltage requirements, to lower the sensitivity one step at a time.
If the UPS still transfers frequently, check the lower/upper trans-
fer voltage window described above).
Output (only on 220/230/240V UPSs) – allows selection of
nominal output voltage.
