Star Module audits

The following audits are performed to report the environmental conditions and
any alarm conditions at the Star Module.
RLD PES audit
The RLD PES audit runs once every hour in the CM. The audit checks each
RLD with a PES system, auditing the SMC alarms. The SMC alarm states are
reported to the CM. The audit procedure compares SMC alarms to the stored
CM alarms. If a mismatch is detected in any alarm element, a log is output and
the CM state changes to match the SMC state for the tested element.
The RLD PES audit is also responsible for the battery test. The batteries must
be tested every 3 months. The RLD PES audit in the CM sends the SMC a
message that requests battery tests at fixed time periods when the right
pre-conditions are met. If the battery test fails, the SMC card sends an alarm
message to the CM. As a result, a PES200 log is output, the alarm is displayed
at the RLDPES level, or in response to the QUERYPES command at the RLD
MAP level.
The SMC monitors the battery voltage and performs battery capacity tests,
The test sequence is as follows:

Note: The battery test cannot be performed if the rectifier fails or less than
72 hours have passed since the end of an ac failure that lasted 1 hour or
more.

the dc charging voltage is reduced for 10 minutes. The battery continues
to feed the load.
the battery voltage is measured every 15 seconds
if the battery voltage is below 48.2 V dc ± 0.2 V dc, the test stops and the
battery test failure is sent to the CM
