10: Reserved/ Programmable output setting
11: Reserved/Shutdown point for programmable output
Interface Setting
“Reserved” will be displayed if the UPS is equipped
with output transformer ratio of 2:1.
The following setting is only available for the UPS with
output transformer ratio of 1:1.
Parameter 3: Sets the programmable output.
You may choose the following three options:
ON: Programmable output is manually switched
on permanently.
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 when the shutdown time is met, the programmable
output will be cut off automatically. After utility power is
restored, the output voltage will resume automatically.
In the event of an overload, the programmable output will
also be cut off automatically. If this is repeated 3 times,
the programmable output will be cut off until it is manually
switched back on again.
Interface Setting
“Reserved” will be displayed if the UPS is equipped
with output transformer ratio of 2:1.
The following setting is only available for the UPS with
an output transformer ratio of 1:1.
Parameter 2: 001.
Sets the shutdown time for the programmable output.
Parameter 3: Shutdown time in minutes.
Setting ranges from 0 to 300. When the shutdown time
is met, the programmable output terminal will be cut off.
The default value is 30 minutes.
Parameter 2: 002
Sets the shutdown voltage for the programmable output.
Parameter 3: Shutdown voltage in V.
Setting ranges 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.
