cylinder using series parallel circuits

Objectives

At the end of this exercise you shall be able to
• select the components to construct and control the Double Acting Cylinder using series and parallel circuits
• construct the circuit on trainer board as per the diagram
• check the function of the circuit.

Requirements

Tools/ Materials
• Pneumatic trainer board - 1 No. • 5/2 DC single solenoid valve - 1 No.
• Digital multimeter with probes - 1 No. • FRL - 2 Nos.
• Regulated DC power • Push button switch - 1 No.
supply 24V/2A - 1 No. • Relay - as reqd.
• Pneumatic Source - 1 No. • PU Tube - as reqd.
• Double Acting Cylinder - 1 No. • Connecting Cables

Procedure
TASK 1: Select the components to construct and control a Double Acting Cylinder using series and
parallel circuits
1 Select the components to construct the circuit using ISO 1219 symbol.
2 Check the DC supply by using multi meter

TASK 2a & 2b :Construct the circuit and control the a Double Acting Cylinder using series and parallel
circuits
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 Solenoid valve to the Input (Piston Rod end side) of the Double
Acting Cylinder
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

Note: Instructor should check the connections properly
Instructor can set the pressure as per requirement

B Electric Connection – Parallel Operation
1 Connect the NO contact (contact no.3) of the Push button switch1 (PB1) to 24V of the power supply.
2 Connect another point of NO contact (contact no.4) of the Push button switch1 (PB1) to A1 of the Relay coil.
3 Connect the NO contact (contact no.3) of the Push button switch 2 (PB2) to 24V of the power supply.
4 Connect another point of NO contact (contact no.4) of the Push button switch 2 (PB2) to A1 of the Relay
coil.
