Setting up Symptoms

A symptom is a keyword or phrase that summarizes the evidence that an operator, engineer, or technician would see when the failure occurs or is about to occur. For example, “trip-alarm sounds” could be defined as a symptom. Symptoms are assigned to MTA2, RCM2, and RBI failure modes to help maintenance personnel track asset faults to the failure modes that could cause them. Symptoms are listed in the Fault Diagnosis Guide, a report you can print for the site, an asset, or a strategy development analysis.

In APM you can define symptoms for selection on failure modes.

To Create a Symptom

1.	On the site’s Strategy Development view, select the Settings tab. Select the Failure Modes tab and the Failure mode settings node in the tree.

Tip: You can also select the site’s Administration menu, Strategy Development Settings, and then Failure Modes. The Failure Mode Management Settings dialog appears.

2.	Select the Symptoms tab.

3.	Click New. The Symptom dialog appears.

4.	Provide a descriptive name for the symptom.

5.	To change the icon that appears for this value, click Change Icon, select a graphic, and click OK.

6.	Enter a description of the symptom.

7.	Click OK to close the dialog. The symptom appears in the tab.

Tip: When the symptom is in use, you can return to this dialog and select the Usage tab. It lists the failure modes that reference the symptom.
