Commissioning Tests
Perform the SDU-2000e commissioning test procedures on the following:
Testing the Output alarms
Testing the SSU-2000e output signals
Testing the Output Alarms
Use the following steps to test the output alarm and reporting software.
1. Remove Power A input power (A-BUS) in connector J101.
2. Verify that the –48/60 V POWER A indicator (LED) on the Buffer modules turns
off.
3. Type
EVENTS and press Enter to verify that an alarm is reported to the
SSU-2000e system. An alarm should be logged into the event log at this time.
4. Replace the A-BUS connector to restore POWER A to the unit.
5. Verify that the alarm clears, and that it is reported and logged into the event log.
6. Verify that the –48/60 V POWER A LED on the Buffer modules is lit green.
7. Repeat Steps 1 through 6 for Power B input power (B-BUS) in connector J102.
Testing the Output Section
Use the following steps to test the output section.
1. Type OUTPUT and press Enter to verify each Output module is operating
without alarms. The Output modules are displayed by position with module status
OK and the selected clock. The clock status indicates the presence or absence
of the four possible clocks A, B, C for bypass, or D for the expansion shelf only.
2. Verify that any outputs configured for redundant pairs are indicated in the status
report. The Priority Quality Level (PQL) will indicate the output SSM level for all
ports and is supplied by the selected clock.
3. Verify that all output ports (which are intended to be active) indicate Y in the port
status.
Testing the System Stability and Accuracy (Optional)
Perform this test only if a primary reference source (PRS) and the necessary test
equipment is available.
If the above tests have been passed, the system output will meet the stability and
accuracy of the reference input.
