Alarm Test
Use the alarm test to simulate a gas concentration for any analyzer.
Note: The alarm test simulates an actual alarm condition and the Vertex M system activates all
alarm relays. Notify appropriate personnel that an alarm test is planned to be conducted.
To conduct an alarm test:
1. Choose Main Screen, Menu, Service and then Alarm Test.
2. Choose the analyzer and point for the alarm test.
3. Choose an alarm level and a simulation scope. Either scope will cause an alarm to be
reported on the control network, on the relays (if equipped) and on the relevant OPC tag.
Furthermore, either scope will cause creation of a simulated alarm event in the event list.
4. However, if Full Simulation With Concentration is selected then a gas concentration will
also be reported on the control network, on the associated OPC tag, on the point detail
screen, and in the event. This concentration will correspond to the alarm 1 or 2 threshold
concentration, depending on which is simulated. The alarm threshold concentration is set
via the configuration utility as described in "Configure Point" on page 60. The Create Alarm
Now button becomes visible only after the prerequisite selections of analyzer, point and
alarm level have been made. Pressing the Create Alarm Now button creates the simulated
alarm. The above screen contains examples of how alarm simulation works. A
concentration of 50 ppb is being reported over the control network and OPC on point 2-2-
3. The value 50 ppb is the alarm 2 threshold for this point from the configuration profile.
However no concentration is being reported for 2-2-5 because the scope was set to Event
And Relays Only when this event was generated. Pressing the Create Alarm Now button
above will create a level 2 alarm with concentrations on point 2-2-4.
5. To continue testing, repeat steps 2 and 3.
If you choose to simulate a Level 2 alarm, both Level 1 and 2 relays will be triggered.
See "Event List" on page 100 to clear events.
