battery test LCD page or by typing RQ0 over the serial port.
BAD AC LINE
Test had to be terminated because AC utility went bad.
TRANS REQUEST
Test was terminated because operator asked to perform a transfer request
during the test.
SYS TURNED OFF
Test was terminated because operator turned the transfer switch to either
the “OFF IDLE” or “OFF” position.
SYS SHUTDOWN
Test was terminated because system shut down for some other reason.
DC LINK DIAG
Test was terminated because of a diagnostic problem with the DC voltage.
This should not normally occur. Call for service.
HIGH DC VOLTS
Test was terminated because the DC voltage went abnormally high. This
should not normally occur. Call for service.
DURATION ERROR
Test was terminated because of an erroneous desired test duration. This
should not normally occur. Call for service.
UNKNOWN
This message is displayed when observing a Quick or Capacity history
record that is active because that test is presently being performed. This
message should not normally occur otherwise. If it is observed at other
times, call for service.
Should you receive a “BATTERY PROBLEM FOUND DURING LAST TEST” Warning, look at the
Manual Battery Test display and the “Batt Test Q” and “Batt Test C” automatic battery test historical
displays for “FAIL” results to determine the severity of the problem.
To set up your UPS for automatic battery testing, press the <SELECT> key to get the main menu.
Select item 9, “SET PARAMETERS”, then select item 2, “AUTOMATIC BATTERY TEST SETUP”.
Refer to section 5.3.6 for details about this display. Make sure that both the Quick and Capacity tests
are enabled. At this time the factory is advising you to select “DAILY” Quick tests and 1 minute
Capacity tests performed every 2 weeks. Doing testing too often or for too long could cause reduced
battery life which would be counter-productive. Not testing often enough reduces the likelihood of
detecting and correcting a problem before it is too late. This is why both a Quick and Capacity test
exists. The Quick test lasts only 3 seconds and is primarily checking the integrity of the batteries to
make sure they can support a load for at least a brief time. Such battery failures often occur without
warning, so the test must be performed often to be effective. The Capacity test lasts much longer and is
checking the capacity of the batteries to determine their effectiveness at supporting a load for extended
periods of time. Capacity problems generally occur slowly, so testing capacity does not need to be
performed as often. Running the Capacity test on a daily basis could reduce the life of the batteries;
however, running the Quick test on a daily basis does not reduce the life of the batteries. If you have
extensive batteries to achieve extended runtimes of an hour or so, you might want to increase the
length of Capacity tests to 3 minutes.
The best battery tests occur when enough current is drawn from the batteries to support the nominal
load. This is only achieved if the battery tests are performed while the UPS is supporting the nominal
load. Therefore, it is important to pick a weekday and hour for when the automatic testing is to be
performed that corresponds to a time when the UPS is supporting its normal load. Do not pick the 3
rd
hour (3 AM) Sunday if over the weekend most of the UPS load is shut off because the office is closed.
Battery testing will not interrupt the normal operation of the UPS, so it is all right to select a weekday
and hour during the day if that is when the UPS is protecting its normal load. It is also important to
verify that the current weekday is correctly programmed into the UPS as viewed on the “Set Date/Time
LCD display.
Personnel responsible for monitoring the UPS, either at the UPS or by viewing a remote display, should
be notified of when battery tests will be performed. When a manual or automatic capacity battery test is
