Symmetra PX; Bypass not in Range messages

Symmetra PX; Bypass not in Range

Symmetra PX

All models, all serial numbers

Bypass not in range messages are generated whenever the AC input voltage goes outside of the acceptable bypass criteria (-10%/+12%).

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

This event can also be generated if the input frequency falls outside the UPS output frequency setting.

You can configure the output frequency on the Power View:

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.
