Data sheets


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.

Preface

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.


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 short-

circuit 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

Introduction



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.

Notes on safety and operation

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.


The technology package TP200 consists of numerous individual training media as

well as seminars. The subject matter of this package is exclusively electropneumatic

control systems. Individual components from the technology package TP200 may

also form a component part of other packages.

• Fixed workstation with Festo Didactic profile plate

• Compressor (230 V, 0.55 kW, maximum 8 bar = 800 kPa )

• Equipment sets or individual components

• Optional training aids

• Practical training models

• Complete laboratory setups

• 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.
