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 TP 200 is comprised exclusively of electropneumatic control systems.
Advanced Level TP 202 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.
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.
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 TP 201 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.).

Work instructions and safety precautions
General
• Trainees should only work with the circuits under the supervision of a trainer.
• Observe specifications included in the data sheets for the individual components and in particular all
safety instructions!
• Faults which may impair safety must not be generated in the training environment and must be
eliminated immediately.
Mechanical setup
• Mount all the components securely onto the profile plate.
• Adhere to instructions regarding positioning of the components.
Electrical setup
• Use low voltage only (max. 24 V DC).
• Electrical connections must only be established and interrupted in the absence of voltage!
• Only use connecting cables with safety plugs for electrical connections.
• Only pull the plug when disconnecting connecting cables – never pull the cable.
Pneumatics
• Do not exceed the maximum permissible pressure of 6 bar (600 kPa).
• Do not switch on the compressed air until all of the tubing connections have been completed and
secured.
• Do not disconnect tubing while under pressure.
• Danger of injury when switching compressed air on!
Cylinders may advance and retract automatically.
• Danger of accident due to tubing slipping off!
– Use shortest possible tubing connections.
– Wear safety glasses.
– In the event that tubing slips off:
Switch compressed air supply off immediately.
• Pneumatic circuit set-up:
Connect the components using plastic tubing with an outside diameter of 4 or 6 mm. Push the tubing
into the push-in connector as far as it will go.
• Switch compressed air supply off before dismantling the circuit.
• Dismantling the pneumatic circuit:
Press the blue release ring down, after which the tubing can be pulled out.

Mounting technology
The mounting boards for the components are equipped with mounting variant A, B or C:
• Variant A, snap-in system
Lightweight components that are not load-bearing (e.g. directional control valves and sensors). Simply
clip the components into the slots on the profile plate. Release the components from the slots by
turning the blue lever.
• Variant B, bolt system
Components with medium load capacity (e.g. pneumatic cylinders). These components are clamped to
the profile plate with T-head bolts. The blue, knurled nut is used for clamping and loosening.
• Variant C, screw system
For components with high load capacity and components which are seldom removed from the profile
plate (e.g. on-off valve with filter regulator). The components are secured with socket head screws and
T-head bolts.

Fundamentals: installation
The layout, tubing and wiring of the components of an electro-pneumatic controller should be selected so
that the total costs for the components, installation and maintenance are as low as possible. With regard to
wiring, selection is made between:
• Conventional wiring technology, e.g. terminal strips
• Modern installation concepts, e.g. wiring with multi-pin plug connection
With regard to layout and the number of drives, as well as tubing, a selection is made between:
• Individual mounting for solenoid operated directional control valves
• Block-type mounting (manifold block or valve terminal)
Comparison of required tubing connections
– Compare the concepts listed above using the controller for this exercise as an example with regard to
minimising tubing connections.
Note
Use the individual valves from TP 201 and the MPA valve terminal from TP 202, as well as the associated
technical descriptions.

Reducing required tube connections
– Which concept enables a reduction of the required tubing connections? Place an X next to your selection
and justify your decision.
Individual mounting of
directional control
valves
Block-type mounting
of directional control
valves
Reason
X
If the directional control valves in the control loops are mounted on a valve
terminal, one length of tubing is adequate for compressed air supply to all control
loops, and one silencer vents all of the exhaust air.
Compared with individual mounting, this solution eliminates numerous tubing
connections and silencers, as well as the need for a compressed air distributor.
The amount of work required for tubing is reduced correspondingly.
Note
Use the individual valves from TP 201 and the MPA valve terminal from TP 202, as well as the associated
technical descriptions.

Reducing required wiring
– Which concept enables you to reduce the wiring? Place an X next to your selection and justify your
decision.
Conventional wiring
technology
Multi-pin plug Reason
X
All valves included in the controller are arranged on the MPA valve terminal (with MP
connection).
As compared with conventional wiring, many of the terminals at terminal strip 2 and
the cables to the solenoid coils are eliminated when the valve terminal is connected
with a multi-pin plug.
Wiring is thus reduced, and maintenance and troubleshooting are simplified.
Note
Use the individual valves from TP 201 and the MPA valve terminal from TP 202, as well as the associated
technical descriptions.

Sequence description
– Describe the controller’s working sequence.
Initial position
In its initial position, cylinder 1A1 is in the rear end-position.
Step 1-2
When pushbutton S1 (NO contact) is activated, relay K1 is picked up and changeover contact K1 in
current path 3 is closed.
The electrical circuit of solenoid coil 1M1 is closed. 5/2-way double solenoid valve 1V1 is reversed as a
result.
The piston end of cylinder 1A1 is pressurised while the piston rod end is exhausted. The piston rod in
cylinder 1A1 advances.
As soon as pushbutton S1 (NO contact) is no longer activated, relay K1 is released and changeover
contact K1 in current path 3 is opened.
The electrical circuit of solenoid coil 1M1 is opened.
Step 2-3
When pushbutton S2 (NO contact) is activated, relay K2 is picked up and changeover contact K2 in
current path 4 is closed.
The electrical circuit of solenoid coil 1M2 is closed. As a result, 5/2-way double solenoid valve 1V1 is
returned to its initial position.
The piston rod end of cylinder 1A1 is pressurised while the piston end is exhausted. The piston rod in
cylinder 1A1 travels to the rear end-position.
As soon as pushbutton S2 (NO contact) is no longer activated, relay K2 is released and changeover
contact K2 opens.
The electrical circuit of solenoid coil 1M2 is opened.
