ELECTRO-PNEUMATIC SYSTEM CONTROL OF MULTIPLE ACTUATORS AIMS: 1. Control Of Multiple Actuator 2. Struktur dan Sistem Nombor Komponen

DISPLACEMENT STEP DIAGRAMS ELECTRO-PNEUMATIC SYSTEM CONTROL OF MULTIPLE ACTUATORS SEQUENCE CONTROL Peranti Pengangkat Untuk Kotak Kotak akan bergerak atas ‘roller conveyor’ dan diangkat oleh silinder A. Silinder B akan menolak kotak ke ‘roller conveyor’ yang kedua. Silinder B tidak akan patah balik sehingga silinder A sampai ke kedudukan asal. DISPLACEMENT STEP DIAGRAMS

DISPLACEMENT STEP DIAGRAMS ELECTRO-PNEUMATIC SYSTEM CONTROL OF MULTIPLE ACTUATORS SEQUENCE CONTROL SIGNAL OVERLAP “Signal Overlap” atau “Opposing Signal” terjadi disebabkan Directional Control Valve yang menerima maklumat angin untuk kedua-dua ‘air pilot signal’ mendapat selangan masa yang terlalu singkat atau pun satu silinder yang bergerak keluar dan masuk tanpa diselangi oleh pergerakkan silinder lain.

DISPLACEMENT STEP DIAGRAMS ELECTRO-PNEUMATIC SYSTEM CONTROL OF MULTIPLE ACTUATORS SEQUENCE CONTROL “Bench Drill” Benda kerja diletakkan ke dalam peranti pengepit (clamping) dengan menggunakan tangan. Cylinder pengepit 1A akan beranjak ke hadapan apabila suis ‘Start’ ditekan. Apabila benda kerja telah dikepit, ia akan di gerudi oleh selinder 2A dan selinder 2A akan kembali ke kedudukan asal setelah selesai proses gerudi. Kemudian selinder 1A akan kembali ke kedudukan asal. DISPLACEMENT STEP DIAGRAMS

DESIGN CIRCUIT ~ Cascade System ELECTRO-PNEUMATIC SYSTEM CONTROL OF MULTIPLE ACTUATORS SIGNAL OVERLAP DESIGN CIRCUIT ~ Cascade System Rules for Applying The Cascade System 1. Definition of the sequence of movement ~ Sequence (add not / displacement) 2. Division into groups ~ Break into group such that no alphabet appear twice into group A+ B+ B- A-
