Course Objectives

On completion of this program participants will be able to;

  • describe and define automated process operation and performance under normal and abnormal condition where a level of risk may arise.
  • apply reliability theory to the solution of practical problems involving electrical, electronic and programmable electronic safety devices.
  • select appropriate electrical and electronic devices based on their characteristics and construct basic safety circuits utilising these components based on IEC 61508 and IEC 61511 standards in low demand mode.
  • specify and verify basic series safety circuits with single input and single output configuration and verify the SIL level provided in low demand mode using Route 1H.
  • source device data sheets, certificates of compliance and understand the schematic circuitry involved in constructing the safety loop.
