Procedure
TASK 1: Select the components to construct and control the speed of a double acting cylinder
1 Select the components to construct the circuit using ISO 1219 symbol
2 Check the DC supply by using multi meter
TASK 2 & 3 : Construct the circuit and control the speed of a double acting cylinder
A Pneumatic Connection
1 Connect the Compressor to the FRL
2 Set the FRL for 6 bar
3 Connect the FRL to the Manifold
4 Connect input port (Port No.1 or P) of the 5/2 Solenoid valve to the Manifold.
5 Connect Output port (Port No.2) of the 5/2 Single Solenoid valve to the Input port of the Throttle Valve.
6 Connect Output port of the Throttle valve to the Input (Piston Rod end side) port of the Double Acting Cylinder
7 Connect another Output port (Port No.4) of the 5/2 Single Solenoid valve to the Input (Piston head end side)
port of the Double Acting Cylinder
