5.2.3 Bypass Mode
When operating in bypass mode set up through UPSilon software, the display
on the front panel is shown as the figure 5-4, the utility power indicator and the
bypass indicator are turned on. Load information area shows load value, and
the battery level area indicates dynamically when the battery is not fully
charged (the battery level icons lit one after another circularly). When the
battery is fully charged, all the level icons are turned on.
1) When operating in bypass mode, the UPS beeps every 2 minutes. If the
“Function” key is pressed for more than 2 seconds, the alarm will not beep
(
silence function
)
. Press the “Function” key more than 2 seconds again to
resume the alarm function.
2) If the utility power indicator blinks, it shows that the voltage or frequency of
the utility power is out of the input range of the UPS or there are problems
with reversed polarity (L/N) of site wiring or disconnect to the ground for
protection.
3) The other four display pages are load percent page, actual load page, input
information page and the maximum temperature page.
Notes: When operating in bypass mode, the backup function of the UPS is not
available and the power used by the load is directly from the utility
power via internal EMI filter.
