9 EG6C/FSS. Faults Simulation System.

Example of some screens

Faults Simulation System (FSS) is a Software package that simulates

several faults in any Computer Controlled Unit. It is useful for

Technical and Vocational level.

The “FAULTS” mode consists in causing several faults in the unit

normal operation. The student must find them and solve them.

There are several kinds of faults that can be grouped in the following

• sections:
• Faults affecting the sensors measurement:
• An incorrect calibration is applied to them.
• Non-linearity.
• Faults affecting the actuators:
• Actuators channels interchange at any time during the program
  execution.
• Response reduction of an actuator.
• Faults in the controls execution:
• Inversion of the performance in ON/OFF controls.
• Reduction or increase of the calculated total response.
• The action of some controls is annulled.
• On/off faults:
• Several on/off faults can be included.
