Taschenbuch. Zustand: Neu. Neuware - An instrumented plant does not have an on switch. It is brought from the end of construction to production through a sequence of gates, each proved before the next may open - and it is not finished when the instruments read and the loops hold, but when you can PROVE they do, and the proof is traceable. Building that proof is a trade, and nobody teaches it as one. You learn it by getting it wrong in the field. This book turns it into a method. It is written for the technician or engineer who inherits a built plant and has to hand it over. - \*\*The nine commissioning gates\*\* - from the installation walkdown to the handover certificate, each with an acceptance criterion and the document that proves it.- \*\*The punch list that closes\*\* - three defect classes, what blocks energization, what blocks handover, and what crosses into warranty declared instead of smuggled.- \*\*Cold loop check versus hot\*\* - what continuity proves, what only a responding process can, and the loop that passes cold and fails hot.- \*\*Proving the remote sites\*\* - point-to-point across a radio path, and the drop-out test done the only way that counts: by removing the radio.- \*\*The functional test\*\* - every interlock fired for real, and the line between a process interlock and a safety function, which is validated elsewhere.>Throughout, one loop - the chlorine cascade - is followed through all nine gates. Every chapter ends by producing a completed field document; the blank forms are in Appendix D to photocopy. This is the fourth and final volume of the series: the measurement made true, the control made to hold, the far network carried home, and the proof that ties them into one plant. \*\*No brand names anywhere.\*\* The volume runs on one fictional plant - Ashford Bend Water Treatment Plant - the same plant as the whole series. The others are not prerequisites.…
