minutes of run time; you must wait for the battery to recharge before using the system.
2. Start a UPS self test; press and hold the ON/TEST button until a beep is heard and the On Line LED
(B) flashes.
During the test the UPS briefly supplies the load from the battery; the On Battery LED (E) is lit. If
the test passes, the On Battery LED goes out and the On Line LED (B) again lights steadily.
If the test fails, the UPS returns to on-line status, but the Replace Battery LED (F) is lit. The
cause should be investigated.
3. To check the input voltage (hospital supply), press and hold the ON/TEST button for at least four sec-
onds (this will start a self test as above):
The Charge/Line Voltage LEDs now indicate the input voltage status; normally two, three, or four
LEDs should light.
If all five LEDs are lit, the input is more than 247 V; if one LED is lit or no LEDs are lit, the input is less
than 213 V.
7 BATTERY CAPACITY RE-CALIBRATION
About once a year, it may be desirable to re-calibrate the battery capacity indicator.
The procedure, including battery recharge, takes about one hour
!
Notice:
It may not be possible to start this procedure immediately after the function check described above,
because it requires the battery charge to be 100% of capacity.
7-1 Battery Capacity Re-Calibration on V1/V2 Control Stations
1. From the Service Desktop, click the Diagnostics button , then the UPS button.
2. To prevent the system from being shut down during the calibration process, select Configuration/
Event Actions, and then the UPS Battery is Discharged event; remove the check mark from the Shut-
down Server box.
3. Note that the calibration process will not start if the battery charge is less than 100%. To display Bat-
tery Capacity (in place of Run Time Remaining), select Configuration/Monitoring Preferences, and
select the parameter to be displayed in the left hand graphical bar of the PowerChute interface.
4. Start the calibration process by selecting Diagnostics/Initiate run Time Calibration.
5. Once started, the calibration process continues until battery capacity falls to 25% (the time from
100% to 25% is about 10 minutes).
With the AWS system powered off and power applied to the UPS, the battery takes 45-60 minutes to
recharge.
6. Before returning the system to normal operation, you must ensure that it will be shut down if battery
capacity is low:
- EITHER: In the PowerChute interface menu, select Configuration/Event Actions, and select the
UPS Battery is Discharged event; click the Shutdown Server box to restore the check mark.
- OR: Log in as root in a command window; execute the command ups stop
