Setting
Parameter 3:
000~999: Set the maximum discharge time from 0 min to 999
min. UPS will shut down to protect battery if the discharge time
arrives before the battery is under voltage. The default value is
990 min.
DIS: Disable battery discharge protection and backup time will
depend on battery capacity.
Setting
Parameter 3: Set programmable output. You may choose the
following three options:
ON: Programmable output is manually switched on timelessly.
OFF: Programmable output is manually switched off. However, if
UPS restarts, this setting will automatically go to "ATO" status.
ATO: Programmable output is automatically turned on or cut off
according to battery or load status. When the battery voltage is
lower than the setting point, or shutdown time arrives, the
programmable output will be cut off automatically. After the utility
is recovering, the output will turn on automatically. If overload
happens, the programmable output also will be cut off
automatically. If it happens 3 times, the programmable output will
be cut off until it is manually switched on.
Setting
Parameter 2: 001.
Set shutdown time for programmable output.
Parameter 3: Shutdown time in minutes.
Setting range is from 0 to 300. When shutdown time arrives, the
programmable output terminal will be cut off. The default value is
30 minutes.
Parameter 2: 002
Set shutdown voltage for programmable output.
Parameter 3: Shutdown voltage in V.
Setting range is from 11.2 to 13.6. If the battery voltage is less
than the setting point, the programmable output will be cut off.
The default value is 11.2V.
Setting
Parameter 2:
N.L: Indicates neutral loss detection function.
Parameter 3:
DIS: Disable the neutral loss detection function. The UPS will not
detect the neutral loss or not.
ATO: The UPS will automatically detect the neutral is lost or not. If
neutral loss is detected, an alarm will be generated, if the UPS is
turned on, it will transfer to battery mode. When neutral is
restored and detected, the alarm will be muted automatically, and
the UPS will go back to normal mode automatically.
