For example, for low gas flow protection to a burner: <\/span><\/p>\nCause<\/strong>: The gas flow gets below 10m3<\/sup>\/h, then FSLL-1234 becomes active
Consequence<\/strong>: The gas flow to the burner is stopped, which affects AOV-1234 and FIC-1234
Crossroads<\/strong>: Valve AOV-1234 is closed and regulator FIC-1234 switches from automatic to manual and the output of the regulator goes to 0%.<\/p>\n<\/div>\n<\/div><\/div>

CE diagrams are conceived by a process engineer and are elaborated on the basis of information from the SIF design. If during the design process or during the life span of the plant, changes to the SIF design occur, you will need to check whether this also affects the cause and effect diagram. <\/span><\/p>\n<\/div>\n
