Chapter 8 Troubleshooting
The HP R3000v UPS is designed for durable, automatic operation and also alerts you
whenever potential operating problems may occur. Usually the alarms shown by the control
panel do not mean that the output power is affected. Instead, they are preventive alarms
intended to alert the user.
Typical Alarms and Conditions
Table 11 describes typical alarms and conditions.
Table 11 Troubleshooting
Alarm or Condition
Possible Cause Action
On Battery
LED is illuminated.
1 beep every 5 seconds.
A utility failure has occurred and the UPS is
in Battery mode.
The UPS is powering the equipment with battery power. Prepare
your equipment for shutdown.
Battery Low
LED is flashing slowly.
1 beep every second.
The UPS is in Battery mode and the battery
is running low.
This warning is approximate, and the actual time to shutdown may
vary significantly. Depending on the UPS load and number of
Extended Runtime Modules (ERMs), the Battery Low warning may
occur before the batteries reach 25% capacity. See Table 9 on
page 37 for estimated runtimes.
On Bypass
LED is illuminated.
1 beep every 5 seconds.
The UPS is in Bypass mode. The equipment transferred to bypass 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. Check for
one of the following alarms: overtemperature, overload, or UPS
failure.
Battery Error
LED is illuminated.
1 beep every second.
The UPS does not recognize the internal
batteries.
If the condition persists, contact your service representative.
The batteries are disconnected. Verify that all batteries are p roperly connected. If the condition
persists, contact your service representative.
The batteries may need replacing. Verify that the batteries are fully charged. If the condition persists,
contact your service representative.
Overload
LED is illuminated.
1 beep every second.
Power requirements exceed the UPS
capacity (greater than 100% of nominal;
see page 36 for specific o utput overload
ranges).
Remove some of the equipment from the UPS. The UPS continues to
operate, but may switch to Bypass mode or shut down if the load
increases. The alarm resets when the condition becomes inactive.
Overtemperature
LED is illuminated.
1 beep every second.
The UPS internal temperature is too high or
a fan has failed.
At the warning level, the UPS generates the
alarm but remains in the current operating
state.
If the temperature rises another 10°C, the
UPS transfers to Bypass mode or shuts down
if bypass is unusable.
If the UPS transferred to Bypass mode, the UPS will return to normal
operation when the temperature drops 5°C b elow the warning level.
If the condition persists, shut down the UPS. Clear vents and remove
any heat sources. Allow the UPS to cool. Ensure the airflow around
the UPS is not restricted. Restart the UPS.
If the condition continues to persist, contact your service
representative.
