Output phase No. set
to 3
The output phase has been changed from 1-phase to 3-phase
The UPS is out of service
Switch on
programmable output
The programmable output status has been changed from Switch Off to Switch On
Switch off
programmable output
The programmable output status has been changed from Switch On to Switch Off
System parallel
settings start sync
Set the 'Sync parallel parameters' command manually to activate the event
The local parameters have been synchronized successfully
All the parameters have been synchronized successfully
Load off due to output
short
There is a short circuit on the inverter or bypass output Carry out the appropriate checks
Output off due to
overload & bypass
abnormal
The output has been switched off due to an overload and the bypass supply is abnormal. Carry out the
appropriate checks
The parallel on-line number and the configured value are inconsistent Please check that the parallel number
on the 'Settings' page is the same as the actual on-line number, and that the parallel cables are normal
If Settings->Output->Frequency is set to 'Auto, BypDisa; 50Hz, BypDisa; 60Hz, BypDisa', the LCD will generate
the BypDisa alarm
In intelligent sleep
mode
When intelligent sleep mode is enabled, the system may perform N sets of inverter start-up.
Conditions for entering sleep mode:
-
The UPS must be connected to a common, large battery string (if there is no large battery string,
entering sleep mode will result in the charger failing to recharge the battery),
-
sleep mode must be enabled on the host,
-
there must be no faults or alarms active on the inverter or rectifier,
-
the battery must not require recharging,
-
a period of at least 1 hour must have elapsed since last exiting sleep mode,
-
the unit is not the master unit
-
with the exception of the module in sleep mode, the local unit ID number has not received a start-
up command within the last 5 minutes.
When the N minus 2 unit rated load is larger than the existing system rated load capacity, the unit with the
largest ID number starts to enter sleep mode (inverter off), at this point, N minus
1
units are operating in
inverter mode.
When the N minus 3 units are larger than the current system rated load capacity, the unit with the largest ID
number remains in sleep mode
Battery cabinet
connection abnormal
The system detects that there are more than six battery cabinets connected and indicates that the battery
cabinet connection is abnormal
Battery cabinet not
connected
The battery cabinet group number is specified, but the communication cables are not connected
Battery end of discharge voltage reached
Press the 'Clear faults' button on the 'Control’ page, the system then records this event
After the user shuts down the UPS output, the system will record this event
In the case of parallel systems, this alarm is generated when the UPS auto-adapting output frequency is
inconsistent. Solution: Switch on again
This alarm occurs when the model identification is incorrect. Solution: Contact service manager
If the alarm is generated as the result of a software value set-up by an authorised VERTIV engineer, and you wish to
modify the setting, please get in touch with your local VERTIV customer service centre.
