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 TP100 is
comprised exclusively of electropneumatic control systems.
Basic Level TP101 is suitable for basic training in pneumatic control technology and
provides knowledge regarding the physical fundamentals of pneumatics and the
function and use of pneumatic components. The equipment set enables you to
construct simple pneumatic control systems.
Advanced Level TP102 focuses on further training in pneumatic control technology.
The equipment set enables you to construct complex combinatorial circuits with
logic operations of input and output signals as well as control systems with
sequencer modules.
Prerequisite for the assembly of control systems is a fixed workstation using a Festo
Didactic profile plate, consisting of 14 parallel T slots spaced 50 mm apart. 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.
Optimal operational reliability is achieved if the control system is operated on
unlubricated air at a working pressure of p = 5 bar = 500 kPa.
The equipment set of Advanced Level TP102 is used to construct complete control
systems for all of the 10 exercise definitions. The theoretical fundamentals to help
you understand this collection of exercises can be found in the textbook
• Pneumatics – Basic Level
Also available are data sheets in respect 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 the
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 roller lever valves manually during fault finding (use a tool).
• Observe general safety regulations (DIN 58126).
• Limit switches must always be mounted laterally to the trip cam (not to the
front).
• Do not exceed the permissible operating pressure (see data sheets).
• Pneumatic circuit assembly: Connect the components 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 additional securing required!
• 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 prior to dismantling the circuit.
• The mounting plates of the devices are in the form of mounting variants A, B or C:
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
For 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
achieved 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
valve with filter regulating valve). These components are mounted by means of
socket head screws and T-head bolts.
• The data for the individual devices, as specified in the data sheets in Part D, must
be observed.

• Training
The training aim of this collection of exercises is the systematic design of circuit
diagrams and the practical assembly of control systems on a profile plate. This
direct interaction of theory and practice ensures quick progress with learning.
Naturally questions and problems arise, which will vary from training group to
training group and these provide a very useful platform for you to discuss the
training aims addressed at the time.
• Variations in training aims
The above training aim can be varied in various different ways. For many
vocational groups, the designing of a control system is only of secondary
importance.
For instance, if the circuit diagram is added to the exercise definition, the
vocational or further training focus can then be shifted to the assembly and
commissioning of the control system.
Other possible main areas of focus in vocational and further training are for
instance fault finding on assembled control systems or the modification of circuit
diagrams, such as circuit documentation due to an altered exercise definition.
Parts of the documentation of a control system can be prepared during the
theoretical part of training.
The preparation of complete solution descriptions or sections thereof based on
the circuit documentation or the assembled control system also facilitates
interdisciplinary tuition.
• Time required
The time required to work through the 10 exercises depends on the prior
knowledge of the trainees:
– Trainees who have undergone vocational training in the engineering and
electrical field:
Just under 160 hours,
– Trainees with technician’s or engineering training:
up to 80 hours.
Whereby the second group is to be involved more in the designing of circuit
diagrams or sections of circuit diagrams.

The designation of components in a circuit diagram is effected in accordance with
the DIN-ISO 1219-2 standard. All components of a circuit have the same main code
number. Letters are assigned depending on component. Several components within
a circuit are number consecutively. The designation of multiple pressure ports is P
and these are consecutively numbered separately.
Cylinders: 1A1, 2A1, 2A2, ...
Valves: 1V1, 1V2, 1V3, 2V1, 2V2, 3V1, ...
Sensors: 1B1, 1B2, ...
Signal input: 1S1, 1S2, ...
Accessories: 0Z1, 0Z2, 1Z1, ...

Mode of operation of a stepper sequencer
A signal is input into the stepper module 1 via input, thereby triggering the output
command, e.g. 1A1+. Step 2 is prepared simultaneously and the last step in the
chain (in this case step 4) is cancelled via the output connection Z.
Step 2 is reset and an output signal, e.g. 2A1, is triggered if step 1 receives the
acknowledgement „step executed" via the limit switch 1B2. Step 3 is prepared
simultaneously and step 1 is cancelled.
The next steps are executed correspondingly.

• To be able to design a stepper sequencer control with idle step.
• To familiarise yourself with the option of facilitating variable step repetitions
within a motion sequence and to assemble this circuit.
• To be able to develop an input circuit with self-latching loop, that enables the
following inputs: AUTOMATIC/MANUAL, START, STOP at CYCLE END AND RESET.
• To be able to select suitable sensors for an application and adjust these sensors
(use of a sensor to detect cardboard boxes in a magazine).
Two double-acting cylinders 1A1 and 2A1 are to operate two magazines. One flat
magazine is to contain the spark plugs and the other the cardboard boxes for the
packaging. Four spark plugs each are to be fed from the flat magazine to a
cardboard box. The number of spark plugs to be packed is to be adjustable.
A cardboard box is to be pushed out of the gravity feed magazine with the advancing
of cylinder 1A1, to be ready for filling. Then, cylinder 2A1 is to execute four double
strokes, thereby separating the spark plugs from the flat magazine. The cycle is to
be completed with the retraction of cylinder 1A1 (gravity feed magazine).
• Switching between MANUAL and AUTOMATIC mode is to be possible by actuating
the valve with selector switch 0S1.
• Actuation of the STOP at CYCLE END pushbutton 0S4 is to start the cycle through
to the end and stop the control system.
• In AUTOMATIC mode, the control system is to operate in continuous cycle.
• When switching to MANUAL, both cylinders are to retract if the RESET
pushbutton 0S2 is actuated and the sequencer is to be returned into the initial
position.
• It must not be possible to start unless cardboard boxes are present. A 3/2-way
valve with selector switch 0S5 is to simulate the conditions „magazine empty“
and „magazine loaded“.
1. Complete the pneumatic circuit diagram and enter the port designations.
2. Carry out the assembly.

Packaging device
1. Actuation of the START button 0S3 is to set up a self-holding circuit with the
control system operating in a continuous cycle. Actuation of the STOP at CYCLE
END button 0S4 is to interrupt the self-latching loop and cancel the stored START
signal. The self-latching loop is to be interrupted also, i.e. it cannot be set up, if
the selector switch 0S5 simulates the condition „magazine empty“, i.e. in the
absence of any packaging material in the stacking magazine.
2. In AUTOMATIC mode, the self-holding circuit and sequencer are to be supplied
with compressed air. If operation is switched to MANUAL via a 5/2-way valve
with selector switch 0S1, the RESET button 0S2 is to be supplied with
compressed air. Its actuation is to cause the two cylinders to retract and the
sequencer to assume the initial position.
3. A pneumatic predetermining counter is to count the advance movements of
cylinder 2A1 and emit a signal to the stepper sequencer when reaching a preset
value.
4. The end positions of cylinder 1A1 are to be monitored using pneumatic proximity
sensors. Two roller lever valves are to monitor the end positions of cylinder 2A1.
5. The cylinder movement in abbreviated notation is:
1A1+ 2A1+ 2A1– 1A1–

Notes
• In practice, a roller lever valve is used to monitor whether the stacking magazine
is full. This is not suitable in this case, since continuous actuation of the valve is
not intended. The use of a 3/2-way valve with selector switch 0S5 is suggested
instead.
• According to the circuit diagram, the stepper sequencer 0Z1 consists of three
modules. The Festo Didactic stepper module is equipped with four modules. You
should therefore bridge the second step by tubing up output A2 and input X2.
The following applies for the bridging of steps:
– The last step must not be an idle step.
– Two idle steps must not be consecutively switched.
• The valves for input are:
STOP at CYCLE END 0S4,
START 0S3,
RESET 0S2,
AUTOMATIC/MANUAL 0S1.
Trial run
Proceed as follows:
1. Reset: "MAN" and "RESET"
2. Start: "AUTO" and "START"
3. Interrupt: "STOP at CYCLE END"

• To familiarise yourself with the option of realising the double stroke of a cylinder
and to be able to assemble this circuit.
• To familiarise yourself with circuits in order to realise the reversal of a cylinder
movement in the partial stroke range.
• To be able to develop an input circuit for a stepper control with protected pilot air
with the inputs START, AUTOMATIC/MANUAL and RESET.
Guide bushes with lapped through holes are to be sealed on both sides using a
plastic plug. The guide bushes are to be manually inserted into the device and the
plugs are to be fed via a gravity magazine.
The START signal 0S4 is to first of all trigger the advancing of the piston rod of the
exhaust air restricted double-acting cylinder 1A1. A plug is to be pressed through
the hole and close the rear righthand opening of the bush. Once the piston rod has
retracted a second plug is to follow and the piston then is to advance halfway and
immediately retract again thereby sealing the front lefthand side of the bush. The
bush can then be removed and a new sequence started.
• Actuation of the EMERGENCY-STOP mushroom actuator 0S1 is to switch off the
compressed air supply. If cylinder 1A1 is in motion, it is to return into the
retracted end position. If cylinder 1A1 is in the forward end position, it is to
remain there.
• If the RESET button 0S5 is actuated, both the cylinder and the stepper sequencer
are to move into the initial position.

1. A single cycle is to be introduced by pressing the START button 0S4. The
AUTOMATIC/MANUAL switch 0S3 is switched to AUTOMATIC for this. The pilot air
supply of the stepper sequencer is to be protected by means of a self-latching
loop via valves 0V3, 0V4 and 0V5.
2. The retracted end position of the cylinder is to be monitored via roller lever valve
1B1 and the forward end position via roller lever valve 1B2. The reversal in the
partial stroke range is to be triggered by the pneumatic proximity sensor 1B3.
3. Roller lever valve 1B1 is to transmit its signal to inputs X2 and X4 of the stepper
sequencer, since a second start takes place within a cycle.

Note
• This is a case where a signalling element actuates two stepper modules
simultaneously.
The magnetic limit switch (1S4) simultaneously operates inputs X2 and X4. If the
second step is reset, then this transmits the pulse. If the fourth step is reset, then
the signal is sent to the cylinder via A4 and resets the stepper module. Both step
outputs are connected via the shuttle valve (0V6), i.e. both the second step and
fourth step emit the pulse to the final control element (1V1) via valves (0V7),
(0V10) and (0V11).
• Design the displacement-step diagram with signal lines.
• Convert an available 5/2-way pneumatic valve into the required 3/2-way
pneumatic valve. Check the functioning of the valve prior to installation.

• To be able to realise a control system with control behaviour in combination with
a sequence control in stepper design.
• To be able to select appropriate sensors for an application and to adjust these.
Sheet metal strips are to be bent using a bending tool. A sheet metal strip is to be
manually inserted into the bending device. Once the START button is actuated, a
cylinder is to clamp the workpiece. The first bending cylinder is to pre-bend the
metal strip and immediately retract again. The second bending cylinder is to
complete the bending of the metal strip. Following this, the second bending cylinder
and the clamping cylinder are to retract simultaneously and the newly formed
bracket is to be removed manually.
• The clamping cylinder is to exhibit monitored behaviour when advancing, i.e. the
sequence control is to be started when the forward end position is reached. If the
START button is released before the cylinder reaches the forward end position, it
is to return into the initial position again.

Bending device
1. The single-acting clamping cylinder 1A1 operates with throttled supply air and is
to be actuated via a spring-returned 3/2-way pneumatic valve. The bending
cylinders 2A1 and 3A1 are to be actuated via 5/2-way double pilot valves and a
stepper module.
2. The end positions of the double-acting bending cylinder 2A1 are to be sensed via
a roller lever valve 2B1 and a roller lever valve with idle return 2B2, and those of
the double-acting bending cylinder 3A1 via a pneumatic proximity sensor 3B1
and 3B2. A back pressure valve 1B2 is to monitor the forward end position of the
single-acting clamping cylinder 1A1 and the retracted end position is to be
monitored via the roller lever valve 1B1.
3. The START button 0S1 must be held down until the clamping cylinder 1A1 is
advanced and the back pressure valve has responded, whereby the stepper
sequencer receives the signal for starting.

4. The bending cylinder 2A1 is to advance and actuate the roller lever valve with
idle return 2B2 in its forward end position. This is to reset the first module and
switch the second step. The bending cylinder 2A1 is to retract immediately again
and actuate the roller lever valve 2B1 in the retracted end position. This is to
reset the second module and switch the third step. Bending cylinder 3A1 is to
advance and actuate pneumatic proximity sensor 3B2 in the forward end
position. This is to reset the third module and switch the fourth step. Clamping
cylinder 1A1 is to be exhausted and return into the retracted end position. At the
same time, the bending cylinder 3A1 is to retract and actuate pneumatic
proximity sensor 3B1 in the retracted end position. This is to reset the fourth
module and consequently the stepper sequencer.
5. The cylinder movement in abbreviated notation is
1A1+ 2A1+ 2A1– 3A1+ 3A1–
1A1–
Notes
• The safety guards required in practice are not taken into consideration.
• Reliable clamping is to be ensured before the bending process is started. The
back pressure valve 1B2 ensures that the metal strip is reliably clamped by the
clamping cylinder. The manually operated valve 0S1 must be actuated until the
back pressure valve 1B2 reacts. This latching safeguards the subsequent
bending operations.
• As the circuit requires 3 roller lever valves, but only two are contained in the
TP101 and TP102 construction kits, valve 2B2 has been replaced by a roller lever
valve with idle return.
• Design the displacement-step diagram with signal lines.
• Convert the available 5/2-way double pilot valves into the required 3/2-way
double pilot valves. Check the functioning of the valves prior to installation.

Exercise 1: Opening and closing of an oven door
Name: Date:
Process description Sheet 1 of 1
Initial position
The oven door is closed. The piston rod of cylinder 1A1 is advanced. The 5/2-way
double pilot valve 1V4 (final control element) pressurises the piston chamber and
exhausts the piston rod chamber. The 5/2-way double pilot valve 1V3 (reversing
valve) is switched to flow from 1 to 4.
Steps 1-2 – opening the oven door
The 3/2-way pneumatic valves 1V1 and 1V2 are actuated simultaneously if the
pushbutton on the 3/2-way valve 1S1 is pressed. Pilot ports 12 and 14 of the
reversing valve 1V3 are exhausted. The compressed air then pressurises the pilot
port 12 of the 5/2-way double pilot valve 1V4 via ports 1 and 4 of the 5/2-way
double pilot valve 1V3. Valve 1V4 switches. The piston rod end of cylinder 1A1 is
pressurised and the piston returns into the retracted end position.
At the same time, the pilot port 12 of the reversing valve 1V3 is pressurised via the
3/2-way pneumatic valve 1V2. The reversing valve 1V3 is connected such as to
enable the reversing of the final control element 1V4 via a new start signal.
Steps 2-3 – closing the oven door
The 3/2-way pneumatic valves 1V1 and 1V2 are simultaneously actuated if the
pushbutton at the 3/2-way valve 1S1 is pressed again. The pilot ports 12 and 14 of
the reversing valve 1V3 are exhausted. The compressed air then pressurises pilot
port 14 of the final control element 1V4 via ports 1 and 1 of the reversing valve 1V3.
Cylinder 1A1 is pressurised at the piston end. The piston rod advances.
At the same time pilot port 14 of the reversing valve 1V3 is pressurised again as a
result of the air via the 3/2-way pneumatic valve 1V1. The control system is in the
initial position again and the oven door can be opened again via a new start signal.

What faults can occur during the tubing up of circuits?
What is the effect of such faults? Describe these.
The 3/2-way valves have not been correctly converted. � Circuit does not function.
Port 2 has been mixed up with port 4 on valve 1V4. � Cylinder does not advance.
How do the 3/2-way valves need to be converted in order to fulfil the necessary
function?
The valves have to be converted to normally open by swapping the blanking plug
and working port.
How do the 5/2-way pneumatic valves need to be converted?
Working port 4 needs to be closed.
Possible solution if a blanking plug is not available: Plug a T-piece (push-in T-
connector) with short tubing onto the valve and connect the remaining two outputs
of the T-piece with a short piece of tubing.
What is the behaviour of the circuit after pressure loss?
The activating circuit stores its status. The result: If the door is moved during
pressure loss, it will return to its previous position if pressure is renewed.
What is a binary reducing stage?
Binary reducing stages are also known as toggle flip flops.
Flip-flops, also referred to as bistable elements, are circuits, that realise basic status
memories.
They assume two statuses: Set and reset. In order to set the flip-flop, a signal needs
to be applied at the input, in this case a pressure signal. The flip-flop then remains in
the set status until a further signal is applied at the input. A binary digit (0 or 1) can
be represented via these statuses.
A binary reducing state changes its status with every active pulse edge, i.e. it acts as
a frequency divider/reducer.

Exercise 2: Separating of drinks bottles
Name: Date:
Process description Sheet 1 of 2
Initial position
Cylinder 1A1 is in the retracted end position. Cylinder 2A1 assumes the forward end
position. The pneumatic proximity sensor 1B1 is actuated. The 5/2-way valve 0S1 is
detented to flow from 1 to 2. The pneumatic predetermining counter 0Z1 is reset and
set to preset value 3.
Separating of drinks bottles
Actuation of the start pushbutton 0S1 causes the pneumatic signal to be switched to
pilot port 14 of the 5/2-way double pilot valve via the 3/2-way valve 0V1 and the
pneumatic proximity sensor 1B1.
Both of the two 5/2-way double pilot valves1V1 and 2V1 are reversed via output 4 of
the 5/2-way double pilot valve 0V2. The piston rod of cylinder 1A1 advances and the
piston rod of cylinder 2A1 retracts.
If cylinder 1A1 moves out of the retracted end position, the pneumatic proximity
sensor 1B1 is no longer actuated and pilot port 14 of the 5/2-way double pilot valve
0V2 is exhausted.
The pneumatic proximity sensor 2B1 is actuated if cylinder 2A1 reaches the
retracted end position. The output signal of the pneumatic proximity sensor 2B1
reverses the 5/2-way double pilot valve 0V2. At the same time, this output signal is
applied to pilot port 12 of the pneumatic predetermining counter and the preset
value is reduced by 1.
Cylinder 1A1 retracts again and cylinder 2A1 advances. This process is repeated
until the pneumatic predetermining counter 0Z1 has counted to 0. Once the value is
0, a pneumatic signal is applied at pilot port 10 of the 3/2-way valve 0V1 by output 2
of the predetermining counter. This causes the air supply to pilot port 14 of the
5/2-way double pilot valve 0V2 to be interrupted.
Cylinder 1A1 is in the retracted end position again and cylinder 2A1 in the forward
end position.

In this exercise, the end position of the double-acting cylinder is monitored via four
different sensors.
Double-acting cylinder 1A1
Retracted end position: 3/2-way toggle lever valve with idle return 1B1
Forward end position: Back pressure valve 1B2
Double-acting cylinder 2A1
Retracted end position: Pneumatic proximity sensor 2B1
Forward end position: Roller lever valve 2B2
Initial position
The double-acting cylinders 1A1 and 2A1 are in the retracted end position. The
pneumatic proximity sensor 2B1 is actuated. The roller lever valve with idle return
1B1 is overtravelled by the trip cam of cylinder 1A1 and therefore not actuated. The
final control elements 1V1 and 2V1 each assume the switching position with flow
from 1 to 2.
Drilling using a vertical feed unit
Actuation of the START button 1S1 causes the final control element 1V1 to switch via
the switched-through pneumatic proximity sensor 2B1. The piston rod of cylinder
1A1 advances and back pressure valve 1B2 is actuated in the forward end position.
The final control element 1V1 is reversed again and cylinder 1A1 retracts.
Drilling using a horizontal feed unit
Just before reaching the retracted end position, the trip cam of cylinder 1A1
overtravels the roller lever valve with idle return 1B1. The final control element 2V1
is switched from 1 to 4 via the output signal of valve 1B1. The piston rod of cylinder
2A1 advances. Upon reaching the forward end position, cylinder 2A1 actuates the
roller lever valve 2B2. The output signal of valve 2B2 reverses the final control
element 2V1. The piston rod of cylinder 2A1 retracts and actuates the pneumatic
proximity sensor 2B1.
The interlock of the START button 1S1 is cancelled. A new cycle can be triggered via
a renewed manual start signal. This ensures that the feed units cannot collide.

How does the circuit react if the roller lever valve is moved?
The cylinder does not fully advance, but only up to the position of the roller lever
valve.
What needs to be considered when mounting the back pressure valve?
It is important to adjust the back pressure valve correctly. On a permanently
installed valve this is facilitated by releasing the lock nut or by twisting the trip cam
on the piston rod. In the test set-up, the back pressure valve is moved along the
profile slot.
If the cylinder impacts on the valve, this can be damaged.

Stepper module Sheet 2 of 3
Mode of operation of a stepper sequencer
A start signal is input at stepper module 1 via input Yn. This triggers the output
command, e.g. 1A1+. At the same time, step 2 is prepared and the last step in the
sequence (in this case step 4) is cancelled via the output connection Z.
If step 1 receives the "command executed" acknowledgement via limit switch 1B2,
step 2 is set and an output signal, e.g. 2A1+ is triggered. At the same time, step 3 is
prepared and step 1 cancelled.
The next steps are run in parallel.

Resetting a stepper sequencer
If the sequencer stops at any step, the currently activated step can be cancelled via a
central reset signal at connection "L". The central reset signal is transmitted to one
of the two OR inputs.

Stepper module Sheet 3 of 3
What are the advantages of a stepper module compared to reversing valve
technology?
Stepper technology has indisputable advantages compared to reversing valve
technology (cascaded control systems) or the use of roller lever valves with idle
return:
• Minimal design complexity (circuit diagram)
• Simplified reading and understanding of circuit diagram (black box principle)
• Less tubing required (assembly time)
• Parameters can be more easily realised
• Less work required when modifying a control system
• Greater operational reliability
• Simplified monitoring via visual indicator and manual override.
What tasks can the individual stepper module assume?
The individual stepper module completes three tasks:
• Switching through (transmission) of signals from input X to output A
• Preparation of the following step
• Cancelling the previous step

Process description Sheet 1 of 2
Initial position
Cylinder 1A1 assumes the retracted end position, the piston rod of cylinder 2A1 is
advanced and roller lever valve 1B1 is actuated. The pneumatic proximity sensor
2B2 is switched through via the permanent magnet on the piston and a signal is
therefore applied at input X4 of the stepper sequencer. Output A4 is active. A signal
is applied at the dual pressure valve 0V1 via Yn+1.
Filling bottles, cylinder 1A1
Actuation of the START button 0S1 causes the memory of the first module (Type A)
to be reset via the dual pressure valve 0V1. The output signal A1 reverses the final
control element 1V1 and the cylinder 1A1 advances. Upon reaching the forward end
position, the cylinder actuates the roller lever valve 1B2. This causes the first
module at input X1 to be pressurised. The spring returned 3/2-way valve of the first
module is reversed and the memory is reset at the subsequent second module (Type
A). The output signal A2 of the second module reverses the final control element
1V1. Cylinder 1A1 returns into the retracted end position. Signal A2 also cancels the
memory valve of the first module. It can only be switched via a new start signal and
the output signal Yn+1.
Bottle release, cylinder 2A1
Cylinder 1A1 in the retracted end position actuates the roller lever valve 1B1. Its
signal acknowledges the output signal A2 at X2 and switches through to the third
module (type A). The output signal A3 reverses the final control element 2V1 and
cylinder 2A1 retracts. The pneumatic proximity sensor 2B1 acknowledges the
movement and switches through to the fourth module (type B) via X3. Its signal
reverses the final control element and cylinder 2A1 advances. The pneumatic
proximity sensor 2B2 acknowledges the end position of the cylinder via X4. The
spring returned 3/2-way valve of the fourth module (type B) is switched. The signal
Yn+1 is applied at the dual pressure valve 0V1 again.

Process description Sheet 2 of 2
Single cycle
If the START button 1S1 is only briefly pressed, i.e. not detented for continuous
cycle, only signal Yn+1 is applied at the dual pressure valve 0V1 at the end of a
cycle. A new cycle cannot be started until the START button is actuated again.
Continuous cycle
If the START button 1S1 is detented, a continuous signal is applied at input 1 of the
dual pressure valve 0V1. A new cycle starts automatically if the initial position of the
cylinder is signalled via connection Yn+1 of the fourth stepper module (type B).
Cycle end
Disengaging the START button 1S1.
Filling of bottles, cylinder 1A1
Actuation of the START button 1S1 triggers the output signal A1 via 0V1, which
switches 1V1 via connection 14. Cylinder 1A1 advances and actuates 1B2. 1B2
triggers the output signal A2 via input X1. 1V1 reverses; cylinder 1A1 retracts and
actuates 1B1. Signal is applied at input X2.
Releasing of bottles, cylinder 2A1
Signal at X2 pressurises output A3. 2V1 reverses; cylinder 2A1 retracts and actuates
2B1. 2B1 effects connection X3 and thus pressurises A4. 2V1 reverses; cylinder 2A1
advances and actuates 2B2. 2B2 produces X4 and Yn+1. Dual pressure valve 0V1 is
pressurised on one side.

How does the circuit react, if sensors 1B2 and 2B2 are displaced?
If the pneumatic proximity sensor 2B2 is displaced when the cylinder is advanced,
the proximity sensor is not attenuated and a start condition is not available. The
system will not start up.
If the roller lever valve 1B2 is displaced such that it is not actuated in the cylinder
end position, the cylinder no longer retracts.

Process description Sheet 1 of 2
Components used:
Delays (t1 = 3 sec; t
2 = 2 sec) are designated. Component 0V1 is the already familiar
time delay valve with normally closed position. Component 0V2 is a time delay valve
with interchanged positions, i.e. normally open. The output signal of this time delay
valve needs to be inverted. A 3/2-way pneumatic valve with normally open position
0V3 assumes this function.
The 5/2-way pneumatic valve with selector switch 0S1 facilitates the switching of
AUTOMATIC/MANUAL. "MAN" in combination with the actuation of pushbutton 0S2
causes the sequencer and cylinder to be reset, i.e. all valves and cylinders assume
the initial position. "AUTO" in combination with the actuation of the START
button 0S2 initiates the automatic execution of a cycle (single cycle).
The delays can be shortened or cancelled via the pushbuttons 0S4 (immersion time)
and 0S5 (draining time).
Initial position
Cylinder 1A1 is in the retracted end position. The pneumatic proximity sensor 1B1 is
attenuated and switched to flow from 1 to 2. Cylinder 2A1 is in the retracted end
position. The roller lever valve 2B1 is actuated. The 5/2-way pneumatic valve with
selector switch 0S1 is switched to AUTOMATIC, flow from 1 to 2.
Steps 1-2
Cylinder 1A1 moves to the right above the electroplating bath (movement 1A1+).
The START signal is input to the first module of the stepper sequencer, connection
Yn, via the 3/2-way valve 0S2 and via the dual pressure valve 0V6, (module 4 is
deactivated via line Z). The final control element 1V1 is reversed via output A1 and
cylinder 1A1 advances.
Steps 2-3
Cylinder 2A1 immerses the wire cage into the electroplating bath (movement
2A1+).
Cylinder 1A1 switches through the pneumatic proximity sensor 1B2. Its signal is
applied at input X1 of the stepper module 0Z1. The sequencer switches through to
the second module. The final control element is reversed via output A2. Cylinder 2A1
advances and actuates the roller lever valve 2B2 in the forward end position.

Process description Sheet 2 of 2
Steps 3-4
Cylinder 2A1 raises the wire cage (movement 2A1-).
After the set time t1 = 3 sec, the time delay valve 0V1 switches to flow. Its signal
pressurises input X2 of the second module of the stepper sequencer. The third
module is reset. The final control element 2V1 is reversed via output A3 and the
shuttle valve 0V8. Cylinder 2A1 retracts and actuates the roller lever valve 2B1 in the
retracted end position.
Steps 4-5
Cylinder 1A moves to the left (movement 1A-).
After the set time t2 = 2 sec, the time delay valve 0V2 exhausts the pilot line of the
3/2-way pneumatic valve 0V3. This switches to normally open. Connection X3 of the
stepper sequencer is pressurised via the shuttle valve 0V5 (the signal switch-off of
the time delay valve 0V2 has been inverted). Signal X3 switches through to the
fourth module. The dual pressure valve 0V7 is supplied with compressed air via
output A4. The final control element 1V1 is reversed via the simultaneously applied
output signal of the roller lever valve 2B1. Cylinder 1A1 retracts and actuates the
pneumatic proximity sensor 1B1. Its signal switches through the fourth module of
the stepper sequencer. The signal Yn+1 is applied at the dual pressure valve 0V6. A
new cycle can now commence via a start signal.

Initial position
The double-acting cylinder 1A1 is in the retracted end position and actuates the
roller lever valve 1B1. The double-acting cylinder 2A1 is advanced and actuates the
pneumatic proximity sensor 2B2. The double-acting cylinder 3A1 is in the retracted
end position and actuates the roller lever valve 3B1. The 5/2-way pneumatic valve
with selector switch 0S3 is detented to flow from 1-2. The 3/2-way pneumatic valve
with the „EMERGENCY-STOP“ mushroom actuator 0S1 is unlatched. The memory
valve 0V2 has flow from 1 to 2. The stepper sequencer is reset.
Continuous cycle
Steps 1-2
Cylinder 1A1 advances, cylinder 2A1 retracts.
The START signal 0S6 switches the memory valve 0V6 from 1 to 4. A continuous
signal is applied at the dual pressure valve 0V7. Combined with signal Yn+1 of the
last module of the sequencer, the dual pressure valve 0V7 is able to input the start
pulse into the stepper sequencer. The output signal A1 simultaneously reverses the
final control elements 1V1 and 2V1 via string s1. Cylinder 1A1 advances and cylinder
2A1 retracts throttled.
Steps 2-3
Feed cylinder 3A1 advances, whereby cylinder 1A1 remains advanced.
As soon as cylinder 1A1 reaches the forward end position and cylinder 2A1 reaches
the retracted end position, the sequencer is advanced via the acknowledgement
signal X1. The dual pressure valve 0V3 ensures that only one signal arrives at X1, if
both the back pressure valve 1B2 and the pneumatic proximity sensor 2B1 are
actuated. Signal A2 reverses the final control element 3V1 via string s2. The double-
acting cylinder 3A1 advances and actuates the roller lever valve with idle return 3B2
in the end position.

Steps 3-4
Cylinder 1A1 retracts, cylinder 2A1 advances.
The acknowledgement signal of the roller lever valve with idle return 3B2 advances
the stepper sequencer by one step via connection X2. The actuating signal A3
reverses the final control elements 1V1 and 2V1 via the pilot line s3. Cylinder 1A1
moves into the retracted end position and actuates the roller lever valve 1B1,
cylinder 2A1 moves into the forward end position and actuates the pneumatic
proximity sensor 2B2.
Steps 4-5
Feed cylinder 3A1 retracts, whereby cylinder 2A1 remains advanced.
Once cylinders 1A1 and 2A1 have acknowledged their end positions (initial position)
(1B1 and 2B2 actuated), the signal of the dual pressure valve 0V4 at input X3
advances the stepper sequencer by one step. The actuating signal reverses the final
control element 3V1 via string s4. Cylinder 3A1 retracts and one cycle is completed.
Two signals are now applied again at the dual pressure valve 0V7, i.e. the
continuous signal from the memory valve 0V6 and the signal Yn+1 from the stepper
sequencer. Consequently all further cycles are executed without a renewed START
signal.

Parameters
• STOP at CYCLE END
The memory valve 0V6, realised via a 5/2-way double solenoid valve in the
exercise, can be converted via the 3/2-way valve with pushbutton 0S5. The line
at the dual pressure valve 0V7 is exhausted. The start signal Yn+1 for the next
cycle is thus blocked via the dual pressure valve 0V7.
• EMERGENCY-STOP
Actuation of the EMERGENCY-STOP valve 0S1 causes the 3/2-way pneumatic
valve 0V1 to be reversed. The memory valve 0V1 is reversed, with flow from
1 to 4. The start processors are exhausted. The final control element 2V1) is
reversed via connection 14. Cylinder 2A1 advances. Port 12 of the final control
element 2V1 is exhausted via the 3/2-way pneumatic valve 0V13. This ensures
that the final control element is able to switch to flow from 1 to 4. The air supply
line to control element 3V1 is exhausted via the 3/2-way pneumatic valve 0V11
and consequently cylinder 3A1 is stationary.
• EMERGENCY-STOP release and RESET
After an EMERGENCY-STOP, the cylinders must be returned to their initial
position. RESET is achieved by actuating the 3/2-way valve via pushbutton 0S4.
The following sequence is to be observed:
1. EMERGENCY-STOP (0S1)
2. Switch from AUTOMATIC to MANUAL (0S3)
3. Release EMERGENCY-STOP (0S2)
4. RESET (0S4)

Process description Sheet 1 of 2
Initial position
The double-acting cylinder 1A1 at the gravity feed magazine is in the retracted end
position and actuates the pneumatic proximity sensor 1B1. The double-acting
cylinder 2A1 at the flat magazine is also in the retracted end position and actuates
the roller lever valve 2B1. The 5/2-way valve with selector switch 0S1 is detented for
flow from 1 to 2 (AUTOMATIC). The 3/2-way valve with selector switch 0S5 is
actuated (a roller lever valve is simulated, which indicates a full cardboard box
magazine).
Continuous cycle
Steps 1-2
Cylinder 1A1 at the gravity feed magazine advances.
The START signal of the 3/2-way valve 0S2 causes the pneumatic valve 0V2 to be
switched to flow from 1 to 2 via the shuttle valve 0V1. The pneumatic valve 0V2
moves into a self-latching loop via valves 0S5, 0V4 (normally open position) and the
shuttle valve (0V1). As a result of this self-latching loop, a continuous signal is
applied at the dual pressure valve 0V5. Combined with the signal Yn+1 of the last
module of the sequencer, the cylinders are actuated. The output signal A1 of the
sequencer switches the final control element 1V1 to flow from 1 to 4. Cylinder 1A1
advances unthrottled and actuates the pneumatic proximity sensor 1B2 in the
forward end position.

Process description Sheet 2 of 2
Steps 2-3 to 9-10
Cylinder 2A1 at the flat magazine executes four double strokes.
The stepper sequencer receives the acknowledgement signal X1 from the pneumatic
proximity sensor and steps up. The output signal A2 of the sequencer, together with
the signal of the actuated roller lever valve 2B1, is applied at the dual pressure valve
0V8 and switches the final control element to flow from 1 to 4. Cylinder 2A1
advances unthrottled and in the forward end position actuates the roller lever valve
2B2. Its signal is applied at the dual pressure valve 0V6 together with signal A2 and
reverses the final control element 2V1. Cylinder 2A1 retracts again. The roller lever
valve 2B2 also transmits a pulse to the counter of the pneumatic predetermining
counter 0Z3. After the set 4 strokes, the output signal of the counter is applied at the
dual pressure valve 0V3. Together with the signal of the roller lever valve 2B1, the
4 strokes are acknowledged at X2 and the sequencer steps up. The pneumatic valve
0V7 is exhausted via the same output signal of the counter. Only one signal is still
applied at the dual pressure valve 0V8 and cylinder 2A1 is therefore no longer able
to advance.
Steps 10-11
Cylinder 1A1 at the gravity feed magazine retracts.
The output signal A3 reverses the final control element 1V1. Cylinder 1A1 retracts
and actuates the pneumatic proximity sensor 1B1. The 3rd module switches through
and its signal Yn+1 initiates a new cycle.
Please note: This module must be the last module of the stepper sequencer. One
module must be bridged.
STOP at CYCLE END
Actuation of the 3/2-way valve 0S4 causes the pneumatic valve 0V4 to exhaust the
self-latching loop. The pneumatic valve 0V2 switches into the normally closed
position and no signal is therefore applied at the dual pressure valve 0V5. The
sequencer can only be activated again via a renewed start signal.
RESET
If the 5/2-way valve with selector switch 0S1 is detented to MANUAL, the cylinders
and sequencer can be moved into the initial position via the actuation of the
3/2-way valve 0S2.

Exercise 8: Sealing of guide bushes
Name: Date:
Process description Sheet 1 of 3
Initial position
The piston rod of the double-acting cylinder 1A1 is in the retracted end position and
actuates the roller lever valve 1B1.
The 3/2-way pneumatic valves 0V5, 0V9, 0V10 and 0V11 assume the normally open
position. The 3/2-way pneumatic valve 0V4, required for the latching circuit,
assumes the normally closed position.
The mode selector switch 0S3 is set to AUTOMATIC (flow from 1 to 2)
Steps 1-2
The piston rod moves into the forward end position.
The START signal of the 3/2-way valve 0S4 causes the pneumatic valve 0V4 to be
switched to flow via the shuttle valve 0V3. The pilot air can now flow to the
sequencer, port P, via valve 0V5. Via the shuttle valve 0V3, this pilot air
simultaneously transmits a continuous signal to the 3/2-way pneumatic valve 0V4.
This valve switches into a self-latching loop and the compressed air supply for the
sequencer is protected. Pressure is applied at both sides of the dual pressure valve
0V6 via the start signal and signal Yn+1 and this switches through. The sequencer is
able to actuate the final control element. The output signal A1 of the sequencer
reverses the pneumatic valve 0V10 and the final control element 1V1 via the shuttle
valve 0V7. The piston rod advances and actuates the roller lever valve 1B2 in the
forward end position. The over-travelling of the proximity sensor 1B3 does not have
any effect.

Process description Sheet 2 of 3
Steps 2-3
Piston rod moves into the retracted end position.
The signal of the roller lever valve 1B2 is applied at intput X1 and steps up the
sequencer. The output signal A2 flows via the shuttle valve 0V8, the pneumatic valve
0V9) and shuttle valves 0V12 and 0V13 and resets the final control element 1V1. The
piston rod retracts and actuates the roller lever valve 1B1.
Steps 3-4
Piston rod advances halfway.
The sequencer is stepped up via the acknowledgement signal X2 of the roller lever
valve 1B1. (The AND gate of the 4th module is not yet prepared and the signal at X4
therefore cannot step up the sequencer. Also, the traversing of proximity sensor 1B3
has no effect, since the 3rd module has not yet been prepared). The output signal A3
flows via the shuttle valve 0V7 and the pneumatic valve 0V10 to the pilot port 14 of
the final control element 1V1 and reverses this. The piston rod advances and
actuates the pneumatic proximity sensor 1B3.
Steps 4-5
Piston rod moves into the retracted end position.
The acknowledgement signal of the pneumatic proximity sensor 1B3 can now step
up the sequencer via connection X3. The output signal A4 flows via the shuttle valve
0V8, the pneumatic valve 0V9 and shuttle valves 0V12 and 0V13 to pilot port 12 of
the final control element 1V1 and reverses this. The piston rod retracts. The roller
lever valve 1B1 acknowledges the end position of the piston rod at connection X4.
The signal Yn+1 is applied at the dual pressure valve 0V6 again and the next cycle
can commence via a new start signal.

Behaviour during EMERGENCY-STOP
EMERGENCY-STOP, piston rod in "forward movement"
If the EMERGENCY-STOP mushroom actuator 0S1 is actuated, the self-latching loop
of the compressed air supply for the sequencer is first of all interrupted via valve
0V5. This means that the sequencer cannot emit any output signals. The signal
blocks valves 0V9 and 0V10 and reverses the final control element 1V1 via valves
0V11, 0V12 and 0V13). The piston rod moves into the retracted end position.
EMERGENCY-STOP, piston rod in "retract movement"
The final control element 1V1 is already switched to flow from 1 to 2. The piston rod
consequently moves into the retracted end position.
EMERGENCY-STOP, piston rod in forward end position
The final control element 1V1 is switched to flow from 1 to 4. The roller lever valve
1B2 is actuated and blocks the valve 0V11. Consequently, the line for the signal to
the final control element is interrupted and the piston rod remains in the forward
end position.
EMERGENCY-STOP release and RESET
After an EMERGENCY-STOP, the cylinders must be returned to their initial position.
RESET is achieved by actuating the 3/2-way valve using pushbutton 0S5.
The following sequence is to be observed:
1. EMERGENCY-STOP (0S1)
2. Switch from AUTOMATIC to MANUAL (0S3)
3. Release EMERGENCY-STOP (0S2)
4. RESET (0S5)

Process description Sheet 1 of 2
Initial position
The piston of cylinder 1A1 is in the retracted end position and actuates the roller
lever valve 1B1; the continuous signal Yn+1 is therefore applied at the dual pressure
valve 0V1. The 4th module (type B) of the stepper sequencer is reset and its signal
A4 blocks the time delay valve 0V3. The pneumatic valve 0V4 is not actuated and is
in the normally open position. Consequently, the pilot port 12 of the final control
element 1V2 is pressurised. The piston rod chamber of the cylinder is pressurised at
a pressure of p = 6 bar (600 kPa).
Steps 1-2
Cylinder 1A1 moves into mid position for annealing.
The first module (type A) of the sequencer is reset via the START signal of the
3/2-way valve 0S1. Its signal A1 actuates the final control element 1V1, i.e. a spring
returned 3/2-way pneumatic valve. The time delay valve 0V3 moves into the normal
position (flow). The pneumatic valve 1V2 moves into the normal position. Cylinder
1A1 advances and in the mid-position actuates the pneumatic proximity sensor 1B3.
Steps 2-3
Awaiting the annealing time, cylinder moves into righthand end position for
quenching.
The acknowledgement signal of the pneumatic proximity sensor 1B3 is applied at
connections X1 and X3 of the stepper sequencer, but can only be switched through
via the reset 1st module. Signal A2 actuates the time delay valve 0V2. The cylinder
remains in the mid-position during the set annealing time of t1 = 3 seconds. Valves
1V1 and 1V2 are exhausted. After 3 seconds, the final control element 1V1 is
switched via the time delay valve 0V2. The cylinder moves into the forward end
position and actuates the roller lever valve 1B2.

Steps 3-4
Cylinder moves into mid-position for start-up.
The acknowledgement signal of the roller lever valve 1B2 switches through to the
3rd stepper module. Its signal A3 switches the final control element 1V2 to flow.
Cylinder 1A1 moves to the left into mid-position and re-activates the pneumatic
proximity sensor 1B3.
Steps 4-5
Awaiting the tempering time, cylinder moves into lefthand end.
The acknowledgement signal of the pneumatic proximity sensor 1B3 switches to the
4th module (type B) of the sequencer via connection X3. The signal at X1 has no
effect, since module 1 is not reset. Signal A4 actuates the time delay valve 0V3. After
the tempering time of t2 = 2 seconds, the final control element is switched to flow via
the time delay valve 0V3. The cylinder moves into the initial position.
A new cycle can be started via a renewed START signal.

Initial position
The three drives are in the retracted end position. Sensors 1B1, 2B1 and 3B1 are
actuated. The memory valve 0V3 is switched to flow from 1 to 2. Memory valve 0V2
is closed.
Steps 1-2
Clamping cylinder 1A1 advances (1A1+).
The final control element 1V1 switches to flow if the START button 0S1 is actuated.
The single-acting clamping cylinder 1A1 advances with throttled supply air and in
the forward end position actuates the back pressure valve 1B2. Two signals (start
signal and acknowledgement signal of movement 1A1+) are applied at the dual
pressure valve 0V1). The final control element 1V1 remains actuated via the memory
valve 0V2 and the shuttle valve 0V4. The clamping cylinder remains in the forward
end position.
Steps 2-3
The first bending cylinder 2A1 advances (2A1+).
A signal is also applied at the dual pressure valve 0V5 via the memory valve 0V2.
Together with signal Yn+1, the first module (type A) of the stepper sequencer is reset
and its signal A1 reverses the final control element 2V1. The bending cylinder 2A1
advances and actuates the roller lever valve with idle return 2B2.
Steps 3-4
The first bending cylinder 2A1 retracts (2A1-).
The second module (type A) is reset via the acknowledgement signal of the roller
lever valve with idle return 2B2 and its signal A2 reverses the final control element
2V1. The bending cylinder 2A1 moves into the retracted end position and actuates
the roller lever valve 2B1.
Steps 4-5
The second bending cylinder 3A1 advances (3A1+).
The acknowledgement signal of the roller lever valve 2B1 causes the third module
(type A) to be reset; its signal A3 reverses the final control element 3V1. The bending
cylinder 3A1 moves into the forward end position and actuates the pneumatic
proximity sensor 3B2.

Process description Sheet 2 of 2
Steps 5-6
The second bending cylinder 3A1 and the clamping cylinder 1A1 retract
(3A1-), (1A1-).
First of all, the acknowledgement signal of the pneumatic proximity sensor 3B2
switches through to the fourth module (type B), and its signal A4 reverses the final
control element 3V1. Cylinder 3A1 retracts and actuates the pneumatic proximity
sensor 3B1. Secondly, the memory valve 0V2 is reversed, as a result of which there
is no continuous signal at the final control element 1V1. The clamping cylinder 1A1
also retracts and actuates the roller lever valve 1B1, whereby the initial position is
obtained again. The fourth module of the sequencer is switched through and its
signal Yn+1 is applied at the dual pressure valve 0V5. The memory valve 0V3 is back
in the righthand switching position (flow from1 to 2).
A new cycle can be started via a START signal.

Equipment set in the organiser
All components of the equipment set for the technology package TP102 are stored in
an organiser within a Systainer. The organiser also serves as a drawer insert for use
in conjunction with our laboratory furniture.
Organiser

The components of the equipment set are intended for assembly on the Festo
Didactic profile plate, which consists of 14 parallel T-slots, set at 50 mm intervals.
Three variants are available for the assembly of equipment on the profile plate:
Variant A
A latching system, without auxiliary means, clamping mechanism with lever and
spring, adjustable in slot direction, for lightweight non-loadable components.
Variant B
A rotary system, without auxiliary means, knurled nut with locking disc and T-head
bolts, vertical or horizontal alignment, for medium weight loadable components
Variant C
A screwed system, with auxiliary means, socket head screw with T-head bolt, vertical
or horizontal alignment, for heavy loadable components and equipment that is
rarely released from the profile plate.
The proven ER units on a plug-in board can be attached to the profile plate using
adapters.
In the case of variant A, a slide is engaged in the T-slot of the profile plate. The slide
is pre-tensioned by means of a spring and, by pressing the blue lever, is pulled back
whereby the component can be removed from or attached to the profile plate.
Components are aligned along the slot and can be moved in the direction of the slot.
With variant B, components are attached to the profile plate by means of a T-head
bolt and blue knurled nut. A locking disc serves to fix the device in position, which
can be secured in all four 90° directions. Components can thus be mounted to the
profile plate either lengthwise or perpendicular to the slot.
Once the desired locking disc position is set, the device is mounted on the profile
plate. By turning the knurled nut in a clockwise direction, the T-head bolt is turned in
the slot by 90° as a result of thread friction. The component is pulled against the
profile plate by further turning the knurled nut.
Assembly technology
D-4 © Festo Didactic GmbH & Co. KG • 541089
Variant C is used for heavy or similar devices, screwed on to the profile plate only
once or removed very seldom. Components are attached by means of socket head
screws with internal hex and T-head bolts.
The time-tested ER units on a plug-in board with locating pins in a 50 mm grid can be
mounted on the profile plate using adapters. A black adapter is required for each
locating pin. The adapters are plugged into the T-slot, positioned at intervals of
50 mm and secured by means of a 90° turn. The locating pins of the ER unit are
plugged into the adapter holes.
The polyurethane tubing is particularly flexible and kink resistant.

The back pressure valve with poppet action and quick push-pull T-connectors is
screwed on to an assembly base. The unit is mounted on the profile plate via a quick
release detent system with blue triple grip nut (mounting alternative „B“).
The back pressure valve with poppet action is actuated via the end face of the
cylinder cam. If the stem is actuated, compressed air exhausts to atmosphere until
the nozzle outlet is closed. At this point, a signal is generated at output 2 up to the
level of the supply pressure. There is thus only low air consumption within the stem
actuation range of 1 mm.
The connections are identified according to the different tubing lengths:
1 = long tubing
2 = short tubing
The supply pressure can be regulated via a restrictor. Prior to the back pressure
valve being used, a functional check should be carried out. If necessary, the back
pressure valve can be adjusted to the cylinder end position by loosening the lock
nut.
The output signal should be amplified if the supply pressure is very low.

Stepper module
2/2 Subject to change © Festo Didactic GmbH & Co. KG, 06/2005
In the case of module type TAB, an OR gate is positioned upstream of the Yn inlet of
the double pilot valve. If a signal is applied at Yn or L, the valve is reversed and a
signal appears at outlet A. In addition, this signal also resets the preceding stepper
module, the visual indicator and the AND gate is supplied with pressure. When the
acknowledgement signal reaches X, the AND flow is released and the signal Yn+1
appears. This signal is also maintained if the entire sequencer is reset at L and can
thus be used for a renewed start. When the sequencer chain is started, the module
is reset externally at port Z via the reset signal Zn+1
of the first module of the
sequencer. With the TAA modules, an OR gate is connected upstream of port Z in the
double pilot valve. This is why, in this case, the double pilot valve is returned via a
signal at Zn+1
from the following stepper.
