Emergency Shutdown System, Type ProSafe-SLS
At the request of Yokogawa, Evaluation International (EI) has issued an edited version of a report written in 1991 on the evaluation of the Maglog-24 Emergency Shut Down System. The Maglog-24 (now known as the Pro-Safe SLS) was evaluated for SIREP (the forerunner of Evaluation International) in 1991 and the results published in report E 1699 S 91. EI has not specifically evaluated the ProSafe-SLS. The original report and the existing manufacturer's technical literature have been thoroughly examined by Suzanne Flynn CEng FIET MCQI CQP BSc(Eng) ACGI FIES FRSA of Cygnet Solutions Ltd to ensure that the content of the new report does fully apply to the ProSafe-SLS. The reader's attention is also drawn to the 2007 report (E 1861 X 07) on the Audit for Compliance against IEC 61508 for the ProSafe-SLS.
