6 Connect another Output port (Port No.4) of the 5/2 Solenoid valve to the Input (Piston head end side) of the
Double Acting Cylinder
7 Fix the Limit switch 1 at home position of the Cylinder piston Rod.
8 Fix the Limit switch 2 at extreme end position of the Cylinder piston Rod.

Note: Instructor should check the connections properly
Instructor can set the pressure as per requirement
Check the Limit switch position

B Electric Connection
