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.
CHE: The UPS will automatically detect the neutral loss. 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, the alarm will NOT be muted automatically and the UPS will NOT go
back to normal mode automatically.
Here, you must mute the alarm and make the UPS go back to normal mode manually.
The operation is: Firstly, enter this menu and press the "Enter" key to make the "CHE"
flash. Secondly, press the "Enter" key again to activate the neutral detection (check). If
neutral is detected, the alarm will be muted and the UPS will go back to normal mode. If
neutral is not detected, the UPS will continue alarming and stay on the latest status until
the neutral is detected well at next manual checking operation.
CHE is default setting.
