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.

“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.

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-

4. Number of reversing switch
~ No of reversing switch required is equal to the nombor of group
Nrs = Ng
