Table 19. Troubleshooting Alarms and Conditions (Continued)
Alarm or Condition
Possible
Cause Action
Redundancy Loss Due to
Overload. The specified
power rating
of the
parallel
system has
been
exceeded. The load is supported, but the system lacks redundant protection while the
overload persists. Remove some of the protected equipment.
Parallel-
Ready
System only.
Parallel
Operation
mode is set
to
“Redundant
Mode.” BladeUPS parallel systems are defaulted to “Redundant Mode.” For a
parallel-ready system (a single UPS installed to be part of a future parallel
system) set the Parallel Operation Settings / Parallel Operation Mode to
“Capacity Mode” to prevent unnecessary alarms.
Configuration Error and the UPS
does not start. The UPS
failed to
identify itself
as a
paralleled
UPS within
two minutes
after utility
power was
applied.
Verify the CAN wiring ( Figure 65 ).
If the condition persists, contact your service representative.
Software Incompatibility
Detected. The UPS
detects a
paralleled
UPS with a
later
firmware
version.
Mixing major firmware versions is not supported. For minor firmware
versions, the alarm does not prevent operation, but different firmware
versions in a parallel system cause conflicts.
Verify that all UPSs in the parallel system have the same firmware version.
For updates, see page 132.
During
parallel
system
startup, the
UPS detects
a UPS in the
system with
a different
OEM number. Verify that all UPSs in the parallel system are from the same manufacturer.
UPSs with different OEM numbers will not parallel.
