Tyco Electronics Galaxy SC Controller J85501F-1
Issue 13 February 2001 Feature Descriptions 7 - 4
Power Major, or Power Minor alarm other than RFA or HV (which may
be generated by the alarm test feature) aborts the alarm test.
Next, the user selectable list of alarm contacts is sequentially activated.
The user can selectively enable each alarm contact for use in the alarm
test, by default all contacts are used in the alarm test. Each selected
contact remains active for a duration of between 5 seconds and 5
minutes, the default value being 1 minute.
After the alarm test, if an RFA is not generated by a rectifier that
processes RFA test, and the rectifier has a Galaxy SC rectifier cable
(with RFA test in the cable), then the Galaxy SC reports the rectifier as
failing the test and creates the Alarm Test Fail Warning.
All incidences of alarm test, alarm test fail, and alarm test abort are
logged in the system history log.
The order of events of the alarm test are:
• Rectifier High Voltage Shutdown for 2 seconds
