Electropneumatics Course

Lesson 1 • Properties of Compressed Air

Covers pressure, flow, and volume relationships governing compressed air. Establishes the physical basis needed to understand all downstream pneumatic circuit behaviour.

Lesson 2 • Safety Standards and Practices

Establishes lockout/tagout, pressure-relief, and electrical isolation procedures. Safe work habits introduced here apply throughout every subsequent hands-on activity.

Lesson 3 • Pneumatic System Architecture

Introduces the layout of a complete pneumatic system from compressor to actuator. Connects component roles to overall system function and energy delivery.

Lesson 1 • Rotary Actuators and Grippers

Introduces vane-type rotary actuators, air motors, and pneumatic grippers. Expands actuator vocabulary needed for multi-axis and handling circuit design.

Lesson 2 • Reading Pneumatic Circuit Diagrams

Teaches systematic interpretation of ISO-standard pneumatic schematics. Prepares students to trace signal paths before adding electrical control elements.

Lesson 3 • Linear Actuator Types and Selection

Compares single-acting, double-acting, and rodless cylinders by force, stroke, and mounting. Guides actuator selection based on load and duty-cycle requirements.

Lesson 4 • Flow Control and Pressure Valves

Covers throttle valves, check valves, and pressure regulators used to shape actuator speed and force. Connects flow control placement to meter-in vs. meter-out strategies.

Lesson 1 • Sensors for Pneumatic Systems

Introduces proximity, reed, and pressure sensors used to detect piston position and system state. Sensor output types are matched to control circuit input requirements.

Lesson 2 • Pushbuttons, Limit Switches, and Indicators

Covers operator interface devices and their wiring in control circuits. Connects human-machine interaction points to the relay and solenoid circuits built in this section.

Lesson 3 • Electromechanical Relays and Contactors

Covers relay coil energisation, contact ratings, and ladder-logic representation. Establishes relay-based control as the baseline before programmable alternatives.

Lesson 4 • Solenoid Valve Coils and Drivers

Explains solenoid coil construction, voltage ratings, and power dissipation. Links coil electrical characteristics to valve switching speed and heat management.

Lesson 1 • Single-Actuator Automatic Cycles

Designs extend-and-retract cycles triggered by sensors and timed events. Demonstrates how sensor feedback closes the control loop for repeatable automatic operation.

Lesson 2 • Electropneumatic Schematic Standards

Applies IEC and ISO drawing conventions to combined electrical and pneumatic diagrams. Consistent documentation enables accurate troubleshooting and team collaboration.

Lesson 3 • Circuit Simulation and Bench Testing

Uses simulation software and physical trainers to verify circuit designs before deployment. Builds systematic test habits that reduce commissioning errors.

Lesson 1 • Sequence Commissioning and Verification

Establishes a structured commissioning process for multi-actuator electropneumatic systems. Students document test results and resolve timing and signal issues systematically.

Lesson 2 • Cascade Control Method

Applies the cascade method to eliminate signal conflicts in relay-based sequences. Students wire and test two- and three-group cascade circuits on training hardware.

Lesson 3 • Sequence Notation and Motion Diagrams

Introduces displacement-step diagrams and sequence notation for multi-actuator systems. Provides a visual planning tool used throughout all subsequent sequencing work.

Lesson 4 • Interlocking and Safety Logic

Adds mechanical and electrical interlocks to prevent unsafe simultaneous actuator motion. Reinforces safety design principles introduced in Chapter 1 within complex sequences.

Lesson 1 • Programme Download, Testing, and Monitoring

Covers project compilation, download procedures, and online monitoring tools. Students verify actuator behaviour against the motion diagram using live status displays.

Lesson 2 • PLC Sequencer and Step Programming

Implements multi-actuator sequences using sequencer instructions or state-machine logic. Replaces hardware step counters with flexible, editable programme structures.

Lesson 3 • PLC Hardware and I/O Configuration

Covers PLC CPU, digital I/O modules, and power supply selection for pneumatic control. Correct I/O mapping is the prerequisite for all subsequent programming tasks.

Lesson 4 • PLC Programme Documentation and Backup

Establishes commenting, tag naming, and backup procedures for maintainable PLC projects. Good documentation practices reduce mean time to repair in production environments.

Lesson 1 • Root Cause Analysis and Corrective Action

Applies five-why and fishbone analysis to prevent fault recurrence after repair. Connects troubleshooting outcomes to maintenance planning and design improvement.

Lesson 2 • PLC-Assisted Fault Finding

Uses PLC online monitoring, alarm logs, and forced I/O to isolate faults quickly. Uses the PLC as a diagnostic instrument rather than only a control device.

Lesson 3 • Pneumatic Diagnostic Techniques

Uses pressure gauges and flow meters to identify leaks, blocked orifices, and valve failures. Pneumatic diagnostics complement electrical checks for complete system analysis.

Lesson 4 • Fault Classification and Symptom Analysis

Categorises faults as electrical, pneumatic, mechanical, or software-related by symptom. Structured classification prevents random part replacement and reduces downtime.

Lesson 1 • Energy Efficiency in Pneumatic Systems

Analyses compressed air consumption and applies pressure zoning, leak reduction, and demand control. Energy optimisation reduces operating cost and environmental impact.

Lesson 2 • HMI Design for Pneumatic Systems

Covers screen layout, tag linking, and alarm display for operator interfaces on pneumatic cells. Effective HMI design reduces operator error and speeds fault response.

Lesson 3 • Proportional Valves and Closed-Loop Control

Introduces proportional pressure and flow valves controlled by analog PLC outputs. Closed-loop position and force control extends capability beyond on/off pneumatics.

Lesson 4 • Industrial Network Integration

Connects PLCs, valve terminals, and sensors via fieldbus and industrial Ethernet protocols. Network integration enables centralised monitoring and reduces wiring complexity.
