1 What does the conceptual design stage mean  [Pg.135]

This is the stage where the control engineer prepares the whole SIS scheme from sensors through logic solver to the final element, control valve or motor trip etc. Some typical issues to be decided at this stage include  [Pg.135]

The selection of the logic solver technology is made...e.g. relays or PES. The architecture of the PES has to be decided. Do we need dual redundant architectures or will a single channel PES be acceptable  [Pg.135]

What type of final element tripping device can we use. Is it serviceable and testable  [Pg.135]
