Table 15. Typical Alarms and Conditions (continued)
Action Possible Cause Alarm or Condition
The UPS does not transfer to
Bypass mode. The bypass utility does not qualify. Check the bypass utility. The UPS is
receiving bypass utility power that may be
unstable or in brownout conditions.
Bypass mode is disabled. Check that the Bypass settings are
configured correctly (see Table 4 on
page 26).
UPS on Bypass
(Notice 169)
Slow Intermittent Alarm The UPS is operating from Bypass
mode. The equipment transferred to bypass utility
power. Battery mode is not available and
your equipment is not protected; however,
the utility power continues to be passively
filtered by the UPS. Check for one of the
following alarms: overtemperature,
overload, or UPS failure.
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.
Verify 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 (EBM).
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.
