Parameter 2: Output Frequency
Setting the output frequency. You may choose following three
options in parameter 2:
50.0Hz:
The output frequency is setting for 50.0Hz.
60.0Hz:
The output frequency is setting for 60.0Hz.
ATO:
I f selected, output frequency will be decided according to
the latest normal utility frequency. I f it is from 46Hz to 54Hz, the
output frequency will be 50.0Hz. I f it is from 56Hz to 64Hz, the
output frequency will be 60.0Hz. ATO is default setting.
Parameter 3: Frequency mode
Setting output frequency at CVCF mode or not CVCF mode. You
may choose following two options in parameter 3:
CF:
Setting UPS to CVCF mode. I f selected, the output frequency
will be fixed at 50Hz or 60Hz according to setting in parameter 2.
The input frequency could be from 46Hz to 64Hz.
NCF:
Setting UPS to normal mode (not CVCF mode). I f selected,
the output frequency will synchronize with the input frequency
within 46~ 54 Hz at 50Hz or within 56~ 64 Hz at 60Hz according to
setting in parameter 2. I f 50 Hz selected in parameter 2, UPS will
transfer to battery mode when input frequency is not within
46~ 54 Hz. I f 60Hz selected in parameter 2, UPS will transfer to
battery mode when input frequency is not within 56~ 64 Hz.
* I f Parameter 2 is ATO, the Parameter 3 will show the current
frequency.
Note: I f the UPS is set to CVCF mode, the bypass function w ill be disabled automatically.
But w hen a single UPS w ithout parallel function is pow ered on w ith mains and before the UPS
finished the startup, there w ill be a few seconds of voltage pulse ( same as the input voltage)
on the bypass output.
I f you need to remove the pulse on this mode to protect your load better, you could contact the
dealer for help.
For the UPS w ith parallel function, this pulse situation w on’t happen.
03: Voltage range for bypass
I nterface
Setting
Parameter 2:
Set the acceptable low voltage for bypass. Setting
range is from 110V to 209V and the default value is 110V.
Parameter 3:
Set the acceptable high voltage for bypass. Setting
range is from 231V to 276V and the default value is 264V.
04: Frequency range for bypass
I nterface
Setting
Parameter 2:
Set the acceptable low frequency for bypass.
50 Hz system: Setting range is from 46.0Hz to 49.0Hz.
60 Hz system: Setting range is from 56.0Hz to 59.0Hz.
The default value is 46.0Hz/ 56.0Hz.
Parameter 3:
Set the acceptable high frequency for bypass.
50 Hz: Setting range is from 51.0Hz to 54.0 Hz.
60 Hz: Setting range is from 61.0Hz to 64.0Hz.
The default value is 54.0Hz/ 64.0Hz.
