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 complete control
systems for all 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.).

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. (DIN 58126 and VDE 100).
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 24V.
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 4 mm outer diameter,
the tubing is plugged 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. On/off
valves with filter regulating valve). These components 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.
