Inconsist
ent
parallel
output
voltage
settings
Critical
You need
to
manually
rectify the
fault or
power off
and
restart
the
device.
The output
voltage
settings of
parallel UPSs
are
inconsistent.
If the output
voltage
settings are
inconsistent,
the non-master
UPS exits the
parallel system.
Otherwise, the
UPS transfers
to bypass
mode because
the number of
parallel UPSs is
inconsistent.
Possible cause: The
output settings are
inconsistent.
Measure: Set the
output voltages to
the same value.

Parallel
CAN
signal
fault
Critical
You need
to
manually
rectify the
fault or
power off
and
restart
the
device.
CAN
communicati
on signals
are lost for
6s in a
parallel
system.
The system
shuts down the
inverter and
transfers to
bypass mode. If
other UPSs in
the parallel
system can
deliver output
in inverter
mode, the UPS
that has
generated the
alarm delivers
no output.
● Possible cause:
The circuit is
faulty.
Measure: Send the
device to the
maintenance
center.
● Possible cause:
The parallel
cable is
disconnected.
Measure: Check the
cable connection.
81
Parallel
UPS host
signal
fault
Critical
You need
to
manually
rectify the
fault or
power off
and
restart
the
device.
The UPS host
signal is lost
for more
than 60 ms
in a parallel
system.
The system
shuts down the
inverter and
transfers to
bypass mode. If
other UPSs in
the parallel
system can
deliver output
in inverter
mode, the UPS
that has
generated the
alarm delivers
no output.
Possible cause: The
circuit is faulty.
Measure: Send the
device to the
maintenance
center.
