Running automatic battery tests
The automatic discharge test is enabled by default and runs during the transition
from Float to Rest mode. After the test is complete, the charge cycle restarts to
completely charge the batteries and then continues to Rest mode. The automatic
test runs approximately once every three months and does not run again until after
three more Float to Rest mode transitions. If a manual battery test is requested, the
automatic battery test timer is reset so that it does not run for the next three
months.
For an automatic battery test to run, make sure that the following requirements are
met:
v The Automatic Battery Tests setting is enabled. (See “Configuring automatic
battery tests.”)
v The batteries are fully charged.
v The UPS is in Normal mode or High Efficiency mode with no active alarms.
v The load is greater than 10%.
v The bypass voltage is usable.
Configuring automatic battery tests
To configure the automatic battery tests, complete the following steps:
1. From the main menu, press the down (
) button to scroll to the Configuration
menu, and press the OK button.
2. Press the down (
) button to scroll to Automatic Battery Tests, and press the
OK button.
3. Press the down (
) button to select whether to enable or disable the automatic
battery test.
4. Press the OK button for 1 second to confirm.
Configuring automatic restart
The UPS automatically restarts if the utility power returns after the output was shut
off because of depleted batteries, a shutdown input signal, or an automatic
shutdown command.
You can set the load segment for the amount of time to delay the restart when utility
power returns by using the Automatic Start Delay setting (see Table 8 on page 32).
