Preface

Festo Didactic’s Learning System for Automation and Technology is orientated towards different training and vocational requirements and is therefore structured into the following training packages: • Basic packages to provide technology-spanning basic knowledge • Technology packages to address the major subjects of open and closed-loop technology • Function packages to explain the basic functions of automated systems • Application packages to facilitate vocational and further training based on actual industrial applications The technology packages deal with the following technologies: Pneumatics, electropneumatics, programmable logic controllers, automation using a personal computer, hydraulics, electrohydraulics, proportional hydraulics and handling technology.


5

Preface

The modular design of the learning system enables applications beyond the limits of the individual packages. For example, to facilitate PLC actuation of pneumatic, hydraulic and electrical drives. All the training packages are of identical structure: • Hardware • Teachware • Software • Seminars The hardware consists of didactically designed industrial components and systems. The didactic, methodological design of the Teachware is harmonised with the training hardware and comprises: • Textbooks (with exercises and examples) • Workbooks (with practical exercises, additional information, solutions and data sheets) • Overhead transparencies and videos (to create an interesting and lively training environment) Tuition and training media are available in several languages and are suitable for use both in the classroom and for self-tuition. Software is available in the form of computer training programs and programming software for programmable logic controllers. A comprehensive range of seminars dealing with the topics of the technology packages completes the range of vocational and further training available.

Introduction

This workbook is a component part of the Learning System for Automation and Technology of Festo Didactic GmbH & Co. KG. This system provides a solid basis for practice-oriented vocational and further training. Technology package TP200 is comprised exclusively of electropneumatic control systems. Basic Level TP201 is suitable for basic training in electropneumatic control technology and provides knowledge regarding the physical fundamentals of electropneumatics and the function and use of electropneumatic equipment. The equipment set enables you to construct simple electropneumatic control systems. Advanced Level TP202 focuses on further training in electropneumatic control technology. The two equipment sets enable you to construct complex combinational circuits with logic operations of input and output signals and program controls. Prerequisite for the assembly of control systems is a fixed workstation using a Festo Didactic profile plate, consisting of 14 parallel T-slots with 50 mm spacing. A shortcircuit protected power supply unit (input: 230 V, 50 Hz, output: 24 V, max. 5 A) is used for DC voltage supply. A mobile, silenced compressor (230 V, maximum 8 bar = 800 kPa) can be used for compressed air supply. Working pressure must not exceed a maximum of p = 6 bar = 600 kPa. Optimum operational reliability is achieved if the control system is operated unlubricated at a working pressure of p = 5 bar = 500 kPa. The equipment set of Basic Level TP201 is used to construct all of the complete control systems of the 12 problem definitions. The theoretical fundamentals to help you understand this collection of exercises can be found in the textbook • Electropneumatics Also available are data sheets in respect of the individual devices (cylinders, valves, measuring devices, etc.).

Introduction

Notes on safety and operation

The following advice should be observed in the interest of your own safety: • Pressurised air lines that become detached can cause accidents. Switch off supply immediately. • Do not switch on compressed air until tubing is securely connected. • Caution! Cylinders may advance automatically as soon as the compressed air is switched on. • Do not operate an electrical limit switch manually during fault finding (use a tool). • Observe general safety regulations. • With electrical limit switches you need to distinguish between two designs – Actuation from the left – Actuation from the right. • At high piston speeds, limit switches must be approached only in the designated direction of the trip cam of the cylinder. Limit switches must not be actuated from the front. • Do not exceed the permissible working pressure (see data sheets). • Only use extra-low voltage ≤ 24 V DC. • All components are equipped with 4 mm safety sockets, i.e. jack plugs. Only use cables with jack plugs for the electrical connections. • Pneumatic circuit assembly: Connect devices using the silver-metallic plastic tubing of 4mm outer diameter, plugging the tubing into the push-in fitting up to the stop; no need for securing! • Releasing of push-in fitting: The tubing can be released by pressing down the releasing ring (disconnection under pressure is not possible!) • Switch off compressed air supply and power supply prior to dismantling the circuit.


9

Notes on safety and operation

• The mounting plates of the devices are equipped with mounting variants A to D: Variant A, latching system For lightweight non loadable devices (e.g. directional control valves). Simply clip the device into the slot in the profile plate. Devices can be released by pressing the blue lever. Variant B, rotary system Medium weight loadable devices (e.g. actuators). These devices are clamped onto the profile plate by means of T-head bolts. Clamping and releasing is effected by means of the blue knurled nut. Variant C, screw system For heavy loadable devices rarely removed from the profile plate (e.g. Start-up valve with filter control valve). These devices are mounted by means of socket head screws and T-head bolts. Variant D, plug-in system Lightweight non loadable devices with locking pins (e.g. indicating devices). These devices are attached by means of plug-in adapters. • The data for the individual devices, as specified in the data sheets in Part D, must be observed.

Methodological help for the trainer

• Training aims The overall aim of this collection of exercises is the systematic design of circuit diagrams and practical assembly of a control system on a profile plate. This direct interaction of theory and practice ensures quick progress with learning. The detailed training aims are documented in the table. Actual individual training aims are allocated to each problem and major training aims are shown in brackets. • Time required The time required to work through a problem depends on the trainee’s prior knowledge. Skilled workers in the engineering and electrical fields require approximately 2 weeks. Technicians or engineers require approximately 1 week. • Components of the equipment set The book of exercises and equipment set are harmonised. For all 18 exercises you only require the components of the equipment set of Basic Level TP201. Each of the Basic Level exercises can be assembled on a profile plate. • Representation Abbreviated notation and motion diagrams are used for the representation of motion sequences and switching statuses.
