Module 6 Activity 01 - OPERATING A PNEUMATIC PRESS DIRECTLY

Objectives: Upon the completion of this task, the student should 1- Explain and use the AND connection practically to ensure a safe operation. 2- Explain and use the OR connection practically. 3- Explain the direct (without using relays) control circuit with AND/OR. 4- Be able to use the FluidSIM software as well as workstations. Problem description: The pneumatic press that is shown in the Figure has to be operated by two switches at the same time in order to protect the operator hands from any possible injury during the press operation. The press will be released automatically by a limit switch. However, another switch has to be provided to release the press in case of the limit switch malfunction.

Observations and Notes Based on the circuit, the electric supply won’t flow through the circuit if we press a single switch alone. We need to press S1 and S2 at the same time before we can activate the cylinder. This mechanism ensures the safety of the operator since his both hands are needed to activate the system....
