This workbook forms part of the Learning System for Automationand Communications by Festo Didactic KG. The system provides asolid framework for practically orientated vocational and further train-ing. Technology package TP200 deals exclusively with electropneu-matic controls.

Introduction

Basic level TP201 provides initial training in electropneumatic controltechnology. Knowledge on the physical fundamentals of electropneu-matics as well as of the function and application of electropneumaticcomponents is conveyed. The set of equipment enables the construc-tion of simple electropneumatic control circuits.

Advanced level TP202 aims to provide further training in electro-pneumatic control technology. The set of equipment can be used tobuild up extensive combination circuits with logic linking of the inputand output signals, as well as programmed control systems.

Precondition for assembling control circuits is a fixed workstationequipped with a Festo Didactic profile plate. The profile plate has14 parallel T-grooves at intervals of 50 mm each. A short-circuit-proofpower supply unit (input: 230V, 50 Hz; output: 24V, maximum 5 A) isused for d.c. supply. For compressed air supply, a mobile silencedcompressor (230V, maximum 8 bar = 800 kPa) is recommended.

Working pressure should be a maximum of p = 6 bar (= 600 kPa)

You will achieve maximum reliability of operation if the control systemis run at a working pressure of p = 5 bar (= 500 kPa), with unlubri-cated air.

The set of equipment for basic level TP201 enables the assembly ofcomplete control systems for solving the problems set in the 20 exer-cises. The theoretical basis required for an understanding of this col-lection of exercises can be found in the following textbook:

Learning System for Automation and Communications■ Electropneumatics, Basic Level TP201

In addition, there are data sheets for the individual components (cylin-ders, valves, measuring devices etc.).

Notes on safety and operation

In the interest of your own safety you should observe the following:■ Pressurised air lines that become detached can cause accidents.

Switch off pressure immediately!

■ First connect all tubing and secure before switching on the com-pressed air.

■ Warning! Cylinders may advance or retract as soon as the compressed airis switched on.

■ Do not operate the electrical limit switch manually during fault find-ing (use a tool).

■ Observe general safety regulations! (DIN 58126 and VDE 100).

■ There are two different designs with electrical limit switches:– Actuation only from the left– Actuation only from the right

■ Limit switches should be fixed in such a way that they contact thetrip cam of the cylinder only in the determined direction. Do notuse them being in the mid-position. Do not actuate limit switchesfrom the front.

■ Do not exceed the permissible working pressure (see data sheets).■ Use only low voltages of ≤ 24 V

■ Pneumatic circuit construction:Use the silver-metallic plastic tubing of 4 mm external diameter toconnect the components. The plastic tube is to be inserted fullyinto the CU-connector up to the stop; no tightening necessary!

■ Releasing the CU quick push-pull connector:The tube can be released by depressing the collet (black ring) (re-leasing whilst pressurised is not possible!)

■ Switch off the air and voltage supply before disconnecting the cir-cuit.

9


■ The mounting boards for the equipment are equipped with mount-ing alternatives A, B, C or D:Alternative A, Detent system Light, non-load bearing components (e.g. directional control valves).Simply clip the components into the groove on the profile plate;release is effected by actuating the blue lever.Alternative B, Rotational systemMedium weight load-bearing components (e.g. actuators). Thesecomponents are clamped on to the profile plate by means ofT-head bolts. The components are clamped or released via theblue triple grip nut.Alternative C, Screw-in systemFor heavy load-bearing components or components, which are sel-dom removed from the profile plate (e.g. the service unit with on-off valve). These components are attached by means of cheesehead screws and T-head nuts.Alternative D, Plug-in systemFor light, non-load bearing components with plug-in bolts (i.e. theindicator plate). These components are mounted via plug-in adap-ters.

■ Observe the data given in the data sheets of section D for individ-ual components.

When carrying out the practical circuit construction, the limit switch S3is replaced by the latching pushbutton switch on the electrical signalinput plate.


Empty magazineWhen the latching pushbutton switch S3 is unactuated the electriccircuit for the audible indicator H1 is closed via contact S3 (31, 32).The electric current supply for the main circuit is switched off via con-tact S3 (13, 14).

Full magazineWhen the latching pushbutton switch S3 is actuated the electric cir-cuit for the audible indicator H1 is opened via contact S3 (31, 32).The electric current supply for the main circuit is switched on via con-tact S3 (13, 14).

Step 1By pressing the pushbutton switch S4 the electric circuit for the relayK1 is closed and the bank of contacts made. When the pushbuttonswitch S4 is released, the electric circuit for the relay K1 remainsclosed via the latching circuit with K1 (13, 14). The electric circuit forthe solenoid coil Y1 is closed with contact K1 (23, 24) and the5/2-way solenoid valve is reversed. The piston rod of cylinder A ad-vances to the forward end position and actuates sensor B2.

Step 2The electric circuit for the relay K2 is closed and the contact K2 ismade. The electric circuit for the solenoid coil Y2 is closed and the5/2-way double solenoid valve is reversed. The piston rod of cylin-der B advances to the forward end position and actuates limitswitch S2. After leaving the retracted end position the electric circuitfor the relay K1 is opened via limit switch S1 and the bank of con-tacts is brought into the normal position. The electric circuit for thesolenoid coil Y1 is opened and the 5/2-way solenoid valve isswitched back to its initial position. The piston rod of cylinder A re-turns to the retracted end position and actuates sensor B1.

Step 3After leaving the forward end position the electric circuit for therelay K2 is opened via sensor B2, and the contact K2 is brought intothe normal position. The electric circuit for the solenoid coil Y2 is op-ened. The electric circuit for the relay K3 is closed and the contactK3 is made. The electric circuit for the solenoid coil Y3 is closed andthe 5/2-way double solenoid valve is switched back to its initial posi-tion. The piston rod of cylinder B returns to the retracted end posi-tion. The electric circuit for the relay K3 is opened via limit switch S2and the contact K3 is brought into the normal position. The electriccircuit for the solenoid coil Y3 is opened.

Mounting technology

The components of the equipment set are mounted on the Festo Di-dactic profile plate. The profile plate has 14 parallel T-grooves equallyspaced 50 mm apart.

There are four alternatives for mounting the components on theprofile plate:

Alternative A: Detent system (also referred to as snap-lock system),without additional facilities,clamping mechanism with lever and spring,which can be moved in the direction of the groove,for light, non load-bearing components

Alternative B: Rotational system, without additional facilities,triple grip nut with locking disc and T-head bolt,vertical or horizontal alignment, for medium-weight load-bearing components

Alternative C: Screw-in system, with additional facilities,cheese head screw with T-head nut,vertical and horizontal alignment,for heavy load-bearing components orcomponents which are rarely removed from the profile plate

Alternative D: Plug-in system, with adapterComponents on plug-in assembly board with locating pins,movable in the direction of the groove,for light, non load-bearing components

The signal input, indicator and relay plates can also be mounted tothe holding frame for ER units.

With alternative A , a slide engages in the T-groove of the profileplate. This slide is pre-tensioned by a spring. By pressing the bluelever, the slide is retracted and the component can either be removedfrom or attached to the profile plate. The components are alignedwith the groove and can be moved in the direction of the groove.

With alternative B , the component is secured to the profile plate bymeans of a T-head bolt and a blue triple grip nut. A locking disc isused for positional attachment, which can be attached in all four 90˚directions. In this way, the components can be secured on the profileplate either parallel or across the groove.

When the locking disc has been adjusted to the required setting, thecomponent is positioned on the profile plate. By turning the triple gripnut clockwise, the T-head nut is rotated by 90o in the T-groove bymeans of thread friction. Further turning of the triple grip nut clampsthe component against the profile plate.

Alternative C is used for heavy components or components whichare screwed on to the profile plate only once or seldom removed.Such components are secured by means of cheese head screws withhexagon socket and T-head nuts.

With alternative D , the tried and tested ER-units for plug-in assemblyboards which have locating pins on a 50 mm grid, can be attachedto the profile plate by means of adapters. One black, plastic adapteris required for each locating pin. The adapters are inserted in theT-groove, positioned at intervals of 50 mm and secured by a rotationof 90˚. The locating pins of the ER-unit are inserted in the adapterholes.
