Malfunctions
- Malfunctions allow the instructor to initiate simulated equipment through tabular indexes, or by expert command. Malfunction insertion may be immediate, time-delayed, or conditional. On variable malfunctions the severity can be set instantaneously or may be ramped over time.A component malfunction feature will be available and supported by the simulation models, which will allow generic failures to be applied to simulated components. For example, the generic malfunction: “Valve Fails Open” may be applied to any valve.Generic component malfunctions include:
- Pumps
- Fans with Inlet Guide Vane (IGV) control
- Transmitters
- Valves
- Control elements such as flow control, temperature control and pressure control
- The malfunctions summary (MFS) is used to monitor the status of active or pending malfunctions. Entries are sorted to show the order of malfunction activation; that is, active malfunctions are first, followed by time-delayed malfunctions, followed by conditional malfunctions. The instructor may compose a set of malfunctions then save it for later use as a composite malfunction.
