Design and Application of Programmable Sequencers to Gas Turbines

THE ADVANTAGE OF PROGRAMMABLE SEQUENCERS over relay logic and mechanical timers is assuming increasing importance since electronic systems are more versatile and reliable. The 1K1 series of programmable sequencers are designed primarily for gas turbine type applications where reliability failure detection, rapid fault finding and quick program changes are of prime importance.

The operation of the sequencer is described emphasising its modular construction its powerful instruction set and the ease with which the system can be defined to operate any size of plant. The failure detection aspect of the system is described showing how failure can be diagnosed to a particular module. Finally various programming aids are described showing how accurate programs can be developed rapidly.
