Remote shut-down has been enabled, and the system will be switched off
The system is in the standby state, and the shut-down dry contact has been enabled Check whether the shut-
down dry contact has been enabled or not
The monitoring board and DSP board versions are incompatible
Short circuit between bus and enclosure or between battery and enclosure. Check for short circuits between
the bus or battery cables and the enclosure
The maintenance bypass state dry contact has been activated
The UPS is in battery mode, and the inverter starts running
The UPS is in bypass mode
The parallel system load demand exceeds the max. load capacity of the parallel sets. Check the parallel
system load demand, and if the system is overloaded, simply reduce the load
After parallel redundancy has been enabled, the system load demand exceeds the rated load capacity (the
load capacity is equivalent to the total capacity of the on-line sets, minus one)
Load sharing is abnormal in the parallel system
System parallel
settings async.
Check that parallel setting parameters of each unit are consistent
Local parallel settings
async.
Check that the Settings pages for the local unit and the other units are consistent
Check that the LBS cables are normal, the system is in stand-by mode, or that the system is in bypass mode
and it is not possible to trace the bypass
The UPS has been shut down because the Normally Closed REPO terminal contact has been opened
In parallel connection configuration, the bypass phase sequence is not consistent. Check the parallel bypass
cable connections
System battery low
pre-warning
In a parallel system, there is a battery voltage low warning for all the devices supplied by the battery inverter
The periodic battery self-test or manual self-test is in progress
The periodic battery self-test or manual self-test is complete
The inverter has switched off because EOD has been reached. Check the mains power-off state and restore
the mains in time
In forced EOD mode, then system shuts down once the battery is fully discharged
Shut-down due to
overtemp
During the UPS operation, the system checks whether the heat sink temperature exceeds the setting range.
In the event of overheating, please check:
1.
If the ambient temperature is too high
2.
If the ventilation holes are blocked by dust
3.
That the fans are working correctly
Dry contact activated causes shut-down irrespective of operating mode
UPS switched off remotely
Load off due to shut-
down on battery
Shut-down in battery mode
Output off due to
bypass abnormal
The bypass is abnormal, and has switched from the working state to the standby state. Check that the bypass
input is normal
Battery to utility
transition
The UPS is powered by the mains instead of the battery
Set power-on via LCD panel
Set shut-down via LCD panel
The UPS output is supplied by the Inverter
Battery series set to
(32-40)
The number of battery cells has been modified
With the UPS in standby mode, select the 'Restore Factory Defaults' function on the Maintain page
Output phase No. set
to 1
The output phase has been changed from 3-phase to 1-phase
