The Spectra system performs the tests in order. In each test, the
system moves valves and changes pump flow rates to create a
specific alarm condition. If the correct alarm occurs when the alarm
limit is reached, the Spectra system proceeds to the next alarm test.
If the correct alarm is not generated, the test fails and the following
screen appears:
See “ALARM TEST FAILED!” on page 12-19 for possible causes of
and actions to remedy this alarm. To restart the alarm tests, press
CONTINUE .
Access Pressure Sensor Alarm Test
The following screen appears:
This test checks the operation of the access pressure sensor and detection
circuit. The system uses the inlet and AC pumps to create an alarm
condition.
When the sensor and detection circuit detect that the access pressure low
limit is reached, an alarm occurs. The following screen appears:
Primary Return Air Alarm Test
The Spectra system uses two different detection circuits to sense air in
the return air chamber. This test checks the operation of the primary
circuit. When the primary detection circuit detects air in the return air
chamber, an alarm occurs. The following screen appears:
