Table 19 contains descriptions of non-critical alarm messages.
Non-critical alarms are not as urgent as critical alarms, but should be
attended to as soon as convenient to avoid the problem becoming
critical.
Table 19. Non-Critical Alarm Messages
Alarm Message What It Means What to Do
Near Low Battery (B) The battery voltage has reached the
Near Low Battery setpoint.
If the voltage increases, the alarm clears automatically. If
it drops further, it will cause a Low Battery alarm.
Low Runtime (D) Batteries in the unit are nearly
discharged.
Perform an orderly shutdown of all equipment and wait
for AC input power to return. When AC input power
returns, the UPS begins recharging batteries and
automatically restarts.
Check Memory (O) The configuration as stored in the
system memory may have been
corrupted.
Look in the alarm log for the slot number of the failed
module. Contact your service representative.
Check Battery (M) The batteries have failed an
automatic system test.
See Table 9 on page 67 and Table 20 on page 86 for
information about reason codes. Contact your service
representative.
Low Redundancy (U) The number of active power modules
is too low to provide the programmed
redundancy level to protect the
current load.
The unit is able to protect the equipment, but will not be
fault tolerant. To regain the desired redundancy, either
add power modules or reduce the load. See Table 9 on
page 67 and Table 20 on page 86 for information about
reason codes.
