Table 14. Typical alarms and conditions (continued)
Alarm or condition Possible cause Action
On Manual Bypass
(Notice 143)
Slow Intermittent Alarm The UPS was manually commanded
to transfer to Bypass mode and will
remain in bypass until commanded. None
Battery Disconnected
(Alarm 199)
Fast Beeping Alarm The UPS does not recognize the
internal batteries. Make sure that all batteries are
correctly connected. If the condition
remains, contact your service
representative.
The battery voltage is lower than the
batteries disconnected level that is
defined for the UPS. This might be
due to a blown fuse, intermittent
battery connection, or a battery cable
that is disconnected.
Low Battery Warning
(Alarm 56)
Fast Beeping Alarm The battery time remaining or battery
capacity is lower than the battery low
warning level that is defined for the
UPS. This warning is approximate. The
actual time to shutdown might vary
depending on the UPS load and
presence of an extended battery
module.
Shutdown Imminent
(Alarm 55)
Continuous Alarm The communication to external
devices stops because the UPS has
entered a state in which it might
abruptly stop operating without further
notice unless utility power returns. The alarm is issued when the
remaining battery time reaches zero.
All connected devices should have
already gone through an orderly
shutdown.
Low Battery Shutdown
(Alarm 174)
Continuous Alarm The UPS has exhausted the battery
capacity and shut down. Resolve the condition that led to
shutdown, then apply utility power for
48 hours to recharge the batteries.
Note: The UPS can be charged with
or without load. The charging can
occur with the UPS connected to a
power outlet (it automatically goes to
Standby mode) and not turned on.
Battery Test Failed
(Notice 191)
Slow Intermittent Alarm A weak battery string was detected
during the last battery test. This is a warning notice. Replace the
batteries soon.
Service Battery
(Alarm 149)
Fast Beeping Alarm A faulted battery string has been
detected, and as a result, the charger
is disabled. Contact your service representative.
Utility Not Present
(Notice 59)
Slow Intermittent Alarm The utility power level has fallen
below the Utility Not Present
threshold (typically <25 to 50 V). The UPS transfers to Battery mode if
it is supporting the load. The UPS
shuts down if it is not supporting the
load.
Bypass Not Available
(Event 105)
No Alarm Utility is outside of the bypass limits
defined in the UPS. Check the bypass settings. See
“Configuration” on page 24.
Input AC Over Voltage
(Alarm 6)
Fast Beeping Alarm The utility power voltage exceeds the
maximum operating range. The UPS transfers to Battery mode if
it is supporting the load.
Input AC Under Voltage
(Notice 7)
Slow Intermittent Alarm The utility power voltage is below the
minimum operating range. The UPS transfers to Battery mode if
it is supporting the load. The UPS
shuts down if it is not supporting the
load.
Input Under/Over Frequency
(Notice 8)
Slow Intermittent Alarm The utility power frequency is out of
usable frequency range. The UPS transfers to Battery mode if
it is supporting the load.
