A scheduled Battery Test will be prevented if a previous scheduled test was prevented, aborted
or had failed within the last 24hrs, this qualification period can be cancelled by toggling the test
enable on, off, on.
If the conditions for a Battery Test are not met when a test is scheduled then the test is
prevented and a time/date stamped entry entered in the Event Log. The system will wait for
the next scheduled Battery Test.
If the conditions for a Battery Test are met then the capacity removed is set to 0, the rectifier
voltage set to 0.5V less than the fail voltage threshold and the capacity taken from the battery is
accumulated.
If the specified capacity is removed before the voltage and time limits are reached the Battery
Test is passed and a time/date stamped entry entered in the event log.
If the fail voltage threshold is reached before the specified capacity is removed the test is failed
and, if enabled in the configuration, the Batt test alarm is active.
If the time limit is reached first the Battery Test is aborted and a time/date stamped entry
entered in the event log.
If during a test any of the following happens:
• a string button is pressed
• any button on state string becomes disconnected for any reason
or
any of the following alarms are active:
• AC fail
• Rect fail
•
Multi rect
• Comms lost
• Overload
or
if a scheduled battery test is set to disabled
or
if a manual test is aborted
then the Battery Test is terminated as aborted and a time/date stamped entry entered in the
Event Log.
A manual test can be requested at any time asynchronous to the scheduled test. If a scheduled
test is running, or prevented by any of the qualification conditions then the manual request is
prevented. If not then a test is started with the same conditions as for a scheduled test. In
addition the manual test can be stopped while active by an abort command.
A manual test will not prevent the next scheduled test from being performed provided the
qualification conditions are met.
A manual test can only be triggered from the MMI using the navigation switch.
