ID Event Description
W5.4 UPS in Test Mode while Run
The UPS has been placed in Test Mode while it is
running.
W5.12 UPS Topology not selected
The topology of the UPS system has not been
selected.
W5.24 DC bus voltage detected high
The averaged DC bus voltage in the system has
risen to a high level.
W5.25 DC bus voltage detected low
The averaged DC bus voltage in the system has
fallen to a low level.
W5.30 String breaker opened
One or more Energy Storage battery string circuit
breakers has been detected as OPENED.
W5.32 Energy Storage bus voltage high timed
The Energy Storage voltage has been detected as
HIGH for a specified period.
W5.34
Energy Storage bus voltage too low
while running
While the system is RUNNING the Energy Storage
voltage has been sensed as TOO LOW.
W5.35
Auxiliary charger (Float charger) failed
or disabled
A failure of the auxiliary charger (float charger) has
been detected. This is determined by detection of
low voltage on Energy Storage bus or by auxiliary
charger fault feedback.
W5.46 DC system or group voltage mismatch
There is a measurement discrepancy in the DC bus
voltage measurements made at various points in
the system.
W5.48 DC bus system imbalance detected
The center point voltage of DC bus is compared
with ground. If this exceeds a preset limit, a
warning is raised.
W5.49
Energy Storage bus system imbalance
detected
The center point voltage of Energy Storage bus is
compared with ground and has EXCEEDED A
PRESET MAXIMUM LIMIT.
W5.51 Energy Storage MCCB not closed
The feedback contact on an Energy Storage MCCB
indicates this MCCB is OPEN.
W5.87 UC120-A trip relay active
The Trip Relay in the UC120-A I/O module (located
on the switchgear) has activated.
W5.88
UC120-A power supply too low or
failed
The power supply voltage of the UC120-A I/O
module (located on the switchgear) has been
deemed as too low.
W5.89 UC120-A control link malfunction
A malfunction has been detected in the UC120-A I/O
module (located on the switchgear) link.
W5.94 PEBB group reduced capacity
The PCS-120 group has reported that one or more
PEBB modules not available.
W5.95 PEBB group not ready
More than the required number of PEBB modules
are stopped.
