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

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.

• 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.

• 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.

the DIN-ISO 1219-2 standard. All components of a circuit have the same main code
number. Letters are assigned depending on components. Several components
within a circuit are numbered consecutively. The designation of pressure ports is P
and these are separately consecutively numbered.

push the sample bottle off the conveyor.
2. When the pushbutton is released, the piston rod is to return into the retracted
end position.

Fundamentals: Normal positions of directional control valves Sheet 3 of 7
An electrically actuated 3/2-way solenoid valve has two switching positions. It can
be in the normal position (unactuated) or in the switching position (actuated). In the
normal position the valve can be open or closed.
– Describe the effects on the motion sequence of the following application arising
as a result of the different normal positions. The single-acting cylinder shown is
controlled by an electrically actuated 3/2-way solenoid valve.

Fundamentals: Mode of operation of different valve types Sheet 6 of 7
Electrically actuated directional control valves are switches with the help of
solenoids. Basically, these can be divided into two groups:
• Spring-return solenoid valves
• Double solenoid valves
– Describe the differences between the two groups with regard to function and
behaviour in the event of power failure.
