Issue:
Symmetra PX; Bypass not in Range
Â
Product line:
Symmetra PX
Â
Environment:
All models, all serial numbers
Â
Cause:
Bypass not in range messages are generated whenever the AC input voltage goes outside of the acceptable bypass criteria (-10%/+12%).
Â
The voltage thresholds are:
Input Voltage - Normal Operation = 166-240Vac (-20/+15%) or 96-138Vac (L-N)
BYP voltage range = 187-229Vac (-10/+10%) or 108-132Vac (L-N)
Output Frequency (sync to mains) 57 - 63 Hz for 60 Hz nominal
Â
This event can also be generated if the input frequency falls outside the UPS output frequency setting.
Â
You can configure the output frequency on the Power View:
60 Hz +/- 0.1 Hz
|
60 Hz +/- 3 Hz
|
60 Hz +/- 10 Hz
|
50Hz +/- 0.1 Hz
|
50Hz +/-3Hz
|
50Hz +/-10Hz
|
Â
For example, if the output frequency is set to 60 Hz +/- 0.1 Hz and the frequency is 60.2 Hz you will have this alarm. If you wish to adjust the output frequency you must do so in Load Disconnect mode.
Â
Resolution:
No action necessary
