Electro Pneumatics

Electrical Multiskill E6: This module introduces candidates to the way in which pneumatics, electrical/electronics and Programmable Logic Control work together within an overall machine control system. On successful completion of this module candidates will be able to:

  • differentiate between a pneumatic or an electrical type of fault
  • observe how programmable logic and sequences can enhance machine automation and control
  • use a variety of electro-pneumatic components to assemble and test a circuit in conjunction with relays and a PLC
  • interpret electro-pneumatic circuits and understand what the various components do within the circuits
  • use electrical and pneumatic fault finding techniques to ascertain the nature of a fault related to the control system, flow, pressure, directional actuator or machine

What you'll learn

The following topics:

  • A revision of basic pneumatics – components, circuits, actuation and control
  • Direct electrical control:
    Establishing correct electrical control using 24V relays and components then using a PLC with associated components and wiring
    Electro pneumatic control
  • Electro pneumatic directional control valves and other component types. Examination of schematic arrangements
  • Pneumatic and electrical circuit symbols, schematic and circuit presentation and correct documentation
  • Fault finding and problem analysis
    Other components
  • Limits: reed switch, mechanical & proximity, proximity
  • Pressure switches, Time delay units
  • Differentiate between air supply, signal and machine related faults

Assemble and test a range of standard pneumatic circuits from a schematic diagram that incorporate a range of pneumatic components. The course will require the candidate to use electrical relay control to begin with and then introduce PLC control as an alternative for comparison and expanded logical and sequential control. The candidate will diagnose a number of specific faults within selected circuits, systems through to component level.

Course Objective

On successful completion candidates will be able work in a cross discipline way with a PLC programme, electrical wiring and pneumatic systems to diagnose and rectify errors and faults.

Time frame

3 day course.
