Slow Intermittent Alarm
Possible cause
The communication to external
devices stops because the
uninterruptible power supply has
entered a state in which it might
abruptly stop operating without further
notice unless utility power returns.
The uninterruptible power supply has
exhausted the battery capacity and
shut down.
A weak battery string was detected
during the last battery test.
A faulted battery string has been
detected, and as a result, the charger
is disabled.
The utility power level has fallen
below the Utility Not Present
threshold (typically <25 to 50 V).
The utility power voltage exceeds the
maximum operating range.
The utility power voltage is below the
minimum operating range.
The utility power frequency is out of
usable frequency range.
An alarm is triggered when the
difference between the ground and
neutral voltage is ≥25 V (tolerance
+50 V, -0 V).
The external contacts in the rear of
the uninterruptible power supply are
configured for remote emergency
power-off operation, and they are
activated.
The load level is at or has exceeded
the configurable threshold limit for a
Level 1 Overload condition.
See "Behavior on overload" on page
26.
Action
The alarm is issued when the
remaining battery time reaches zero.
All connected devices should have
already gone through an orderly
shutdown.
Resolve the condition that led to
shutdown, and then apply utility
power for 48 hours to recharge the
batteries.
This is a warning notice. Replace the
batteries soon.
Contact your service representative.
The uninterruptible power supply
transfers to Battery mode if it is
supporting the load. The
uninterruptible power supply shuts
down if it is not supporting the load.
The uninterruptible power supply
transfers to Battery mode if it is
supporting the load.
The uninterruptible power supply
transfers to Battery mode if it is
supporting the load. The
uninterruptible power supply shuts
down if it is not supporting the load.
The uninterruptible power supply
transfers to Battery mode if it is
supporting the load.
Have a qualified electrician correct
the wiring problem. If the
uninterruptible power supply is not
wired with a neutral wire, change the
Site Wiring Fault Alarm to Disabled
in the Settings menu (see Table 8 on
page 24).
The uninterruptible power supply
de-energizes the load and enters
Standby mode. For more information,
see "Installing the remote emergency
power-off" on page 15.
The uninterruptible power supply can
support the load indefinitely at this
load level.
The alarm clears when the load drops
below 5% of the set point.
