Operating Modes
The HP R3000v UPS front panel indicates the UPS status through the UPS indicators (see
Figure 14 on page 17).
Normal Mode
During Normal mode, the (Power On) indicator illuminates and the UPS is powered
from the utility. The UPS monitors and charges the batteries as needed and provides filtered
power protection to your equipment.
Battery Mode
When the UPS is operating during a power outage, the alarm beeps once every five
seconds and the
(On Battery) indicator illuminates.
When the utility power returns, the UPS transfers to Normal mode operation while the
battery recharges.
If battery capacity becomes low while in Battery mode, the (On Battery) indicator
flashes slowly and the audible alarm beeps once every second. If the Battery Low alarm is
set, the
(Alarm) indicator also illuminates. This warning is approximate, and the actual
time to shutdown may vary significantly.
NOTE:
Depending on the UPS load and the number of Extended Runtime Modules (ERMs)
connected, the Battery Low warning may occur before the batteries reach 25% capacity. See
Table 9 on page 37 for estimated runtimes.
When utility power is restored after the UPS shuts down, the UPS automatically restarts.
NOTE:
You can configure the auto-restart option through the HP Value UPS Manager software
(see page 23).
Bypass Mode
NOTE:
You can manually transfer the UPS to Bypass mode by pressing the (Output Off)
button once within four seconds. If Bypass mode is not available, the UPS returns to its original
operating mode.
NOTE:
You can configure Bypass mode options through the HP Value UPS Manager software
(see page 23).
In the event of a UPS overload or internal failure, the UPS transfers your equipment to utility
power. Battery mode is not available and your equipment is not protected; however, the
utility power continues to be passively filtered by the UPS. The
(Bypass) indicator
illuminates.
The UPS remains in Bypass mode for at least five seconds (if the bypass source remains
acceptable). If three transfers to bypass occur within 10 minutes for any reason other than
user command, the UPS locks in Bypass mode for one hour or until any control button is
pressed.
