1 General information
Press-Right is a monitor and measuring device that is connected to a press and monitors the quality
of productive processes.
Being interfaced with a displacement transducer and a load cell, it continuously monitors its
positions and instantaneous force.
1.1 Introduction to the monitoring theory
During sample production, the data regarding cylinder position and the force exerted by it are
entered; the following graph may be created: position-force representing production.
If several runs are performed on similar pieces, their position-force curves will also be similar. On
the other hand, if one of the manufactured pieces is different from the sample, its curve will be
different from the sample. It is clear that monitoring the curve may affect the quality of
manufacturing.
This product must not be disposed of as an unsorted urban waste; secure proper
recycling.
1.2 Characteristics of the device
Press-Right manages and monitors the profile of the cylinder speed.
It works on a continuous tolerance range monitoring the whole position-force curve.
It monitors the peak position and the peak force values.
It stops the press once a position target or force target is reached.
It monitors the initial height measured upon contact with the piece.
It monitors critical points through position-force curve check points.
It manages up to four consecutive phases with independent parameters.
All parameters are saved in 200 independent and selectable jobs.
Advanced management of users by means of passwords and personal authorizations.
Press-Right may be connected to the computer and, by means of the WinScope software, it may
save curves, edit settings, run statistical analyses, print data.
Saving curves on the SD memory card.
It allows the connection of up to three enabling signals.
It allows the connection of up to three additional OK/NOK check signals.
Programmable periodic self-verification function.
Programmable periodic request for the replacement of worn-out tool.
Programmable periodic request for maintenance.
1.3 Device operating principle
The Press-Right PE is sold together with an electric press: it measures the position of the cylinder
instant by instant, and the force exerted by the cylinder by using a force transducer instant by
instant.
In order to increase the precision of its height, it may be associated with an external micrometric
probe.
The work phases (pressing) are performed as follows:
 Fast approach up to a END APPROACH POSITION at the APPROACH SPEED
 Pressing job at the WORK SPEED up to the FINAL POSITION or up to the STOP FORCE
 Stationing on the piece for a time set as WAITING BEFORE RETURN
 Return to the RETURN POSITION at the RETURN SPEED

 If necessary, it is possible to run the last stretch of the work range at low speed by setting the
PRE-STOP POSITION and the PRE-STOP SPEED.
1.3.1 Absolute and relative positions
The positions referred to the cylinder zero point are referred to as absolute positions. The positions
referred to the contact point on the manufactured piece are referred to as relative positions. Press-
Right may set both the absolute and the relative positions. In order to measure the contact point on
the manufactured piece, Press-Right use the force transducer: when the force measured exceeds the
START FORCE planned value, the relative zero point is set. This zero point is called conctact
position. The conctact position may be monitored by using two limits, a minimum and a maximum
value (Chapter 5.2).
 Cylinder zero point
 Retorn position (rest)
 Relative zero point (start position)
Figure 1
The precision of the conctact position measured with the load cell may not be increased. It depends
on the cylinder speed and, in particular, on the type of piece to be manufactured. During the shrink-
fitting operations, the two pieces show chamfered edges; as a result the conctact position varies also
based on the chamfer and the force used to position a piece into the other.
1.3.2 Position-force value monitor
Press-Right enjoys different functions. The curve monitoring is performed by a tolerance range
(chapter 6) and its limits (chapter 5.2). The limits are the following: minimum and maximum force,
minimum and maximum position; they can be set or excluded and they monitor the maximum value
obtained during the production. If the position reached does not exceed the minimum position
and/or exceeds the maximum position, the piece is rejected. At the same time, if the maximum force

reached does not exceed the minimum force and/or does exceed the maximum force, the piece is
rejected.
From a theoretical point of view there is an ideal curve that may be obtained by manufacturing
perfect pieces (in practice a sample curve may be obtained by carefully manufacturing selected
pieces). Any geometric tolerance or difference in materials result in a curve that is different from
the ideal curve. In practice, there is a tolerance range around the sample curve such that, if the curve
obtained from the current process does not stay inside such range, the piece is classified as scrap.
The piece is good only if the analysis of the minimum/maximum limits and the tolerance range have
a positive result. Press-Right also monitors the cylinder return at the end of the production process.
Such return may result from the exertion of a specific force (stop force) or at a specific position
(final position). It is possible to set both force and position stop values at the same time; in this case
the first value to be entered will govern the cylinder return. By changing the value of the
configuration, it is also possible to command the cylinder return when the curve is off the tolerance
range. It is always possible to have the unit return by pressing the key on the keypad
(stopping the operation).

2 Installation of Press-Right
For the installation of the device on the machine, please refer to the specific manual.

3 Getting started
This chapter provides information on how to set up basic operations and using the Press-Right
device.
To better describe the operations, run practical tests.
Figure 2
To turn the device on use the key on the rear side. When it is pressed, after a few seconds, the
display turns on and the graph appears:
Figure 3
3.1 The keyboard of Press-Right
If the key is pressed, at the bottom of the display, a box appears divided into four parts
showing the items of the main menu; above this box, the menu title is highlighted. To select an item
of the menu, touch it.
The key cancels the operations and takes you back to the upper menu.
The key is used to confirm the values entered from time to time.
The key allows to cancel typing errors. When a menu is displayed, pressure allows to go back
to the initial screen. If no menu is displayed, it allows to activate the cursor.

3.2 First approach
First of all, get acquainted with the press by performing a number of manual motions.
To do so, proceed as follows:
- press the
- press the TOOLS item
- press the MANUAL MOVING item
- press the ENABLE JOG item
By using the keys, the cylinder may be moved.
Note: manual movements are possible outside the nominal range of the cylinder or with a load
applied to it, only at the minimum speed.
The lot of all parameters applied to the production process are referred to as Job.
First of all, let's create a simple Job:
press the
press the JOBS MANAGEMENT item
press the CREATE A NEW JOB item.
Note: in the following pages, when, for example, the phrase "select the JOBS MANAGEMENT >
CREATE A NEW JOB command" is reported, it means that key must be pressed,
followed by the JOBS MANAGEMENT item and then press the CREATE A NEW JOB item.
Enter the name to identify the job (e.g., TEST 1) and press the key.
Note: it is possible to create a sequence of jobs to be performed as individual phases on the same
piece.
Once the job is created, enter the motion parameters: JOBS MANAGEMENT > EDIT JOB > EDIT
PHASE > PHASE PARAMETERS > MOTION SETTINGS .
Then, before moving to the automatic operation, enter the parameters in the motion profile:
FINAL POSITION
The position to be reached.
STOP FORCE
Force commanding the stop of cylinder before the final position.
END APPROACH POSITION
Position to be reached during the rapid approach to bring the piece closer. Such position must
be lower than the piece height at contact. If the force is measured during the approach stroke,
the system runs a collision alert.
RETURN POSITION
Return position at the end of the pressing cycle. The cylinder is not required to go back to the
zero cylinder position.
WAITING BEFORE RETURN
In some cases it may be useful to stop the cylinder at the press end position for some seconds.
WORK SPEED
Press stroke speed.
APPROACH SPEED
Stroke approach speed while bringing the piece closer.
RETURN SPEED
Return speed at the end of the production process at rest height.
PRE-STOP POSITION
Pre-stop stroke initial position.

11
PRE-STOP SPEED
Speed at which the cylinder runs the last stroke starting from the PRE-STOP POSITION. During
the pre-stop stroke, the cylinder regulates the speed according to the force value measured.
Now, before continuing, make sure that there is At least a 50mm free space in the stroke of the
cylinder.
Enter the following values:
FINAL POSITION = 50mm
END APPROACH POSITION = 40mm
WORK SPEED = 2mm/s
APPROACH SPEED = 20mm/s
RETURN SPEED = 50mm/s
With these settings, when the start command is pressed, the cylinder will start from its position. If
the cylinder is not in the zero position, it will return to the zero point, on the contrary the whole
cycle will be executed.
3.3 Set visualization
The central section of the display is occupied by the position-force graph. It is possible to edit the
full scale values by the menu command JOBS MANAGEMENT > EDIT JOB > EDIT PHASE > SET
GRAPH (paragraph 4.9).
3.4 Using the menus
If the key is pressed, in the lower section of the screen the main menu is displayed.
When a menu is displayed or when a value is entered, by keeping the key pressed , it will be
possible to briefly visualize the graph and the curve.
When the key is pressed to show the main menu, it is possible to press the 8 key to change
language. In addition, if the device is connected to several load cells, it is possible to press the 1 to 6
keys to hide curves related to each cell, which will still be kept active.
3.5 The main menu
The main menu is the first to be visualized by using the key.
When the main menu is visible, keys have special functions as described in paragraph 3.5.1.
The first item of the main menu is JOBS MANAGEMENT. This item allows for the creation and the
selection of jobs. It also allows to change the job work parameters, the job options and the range.
See chapter 4.
The second and third items may be edited from the following menu TOOLS > DISPLAY
MANAGEMENT > PREFERENCES > ENTER FIELD VALUES .
The forth item of the main menu is TOOLS. By using this menu it is possible to change the
configuration of the device and move to the manual operation.
3.5.1 The special functions of keys in the main menu
If menus are not displayed, press the key to display the main menu together with the
windows showing the special key functions.

12
Figure 4
CURSOR
By using the key it is possible to show the cursor to measure the force in a specific point on
the curve. (chapeter 8.2).
LANGUAGE
The 8 key allows to change the device language. Two languages are available and are uploaded
via the Press Right Setup software.
CHANNELS
The 1 to 6 keys allow to select whether to visualize or hide the curves of each channel when
there are more than one (chapter 4.12). In the upper-right window all channels are shown and
over each of them a small hyphen appears signifying that the channel is visualized. In Figure 4
it is possible to see the status of both channels in a Press-Right equipped with two force
transducer: the curve of channel 1 is not visible, while the curve of channel 2 is visible. Even
when the curve of a channel is not displayed, it will be monitored in any case.

13
4 The JOB
Press-Right stores all settings (parameters, range and counters) referring to the Job. There may be
at least 100 of them, each of which with its own name.
The main menu also includes the JOBS MANAGEMENT item. By means of this sub-menu, it is possible
to create a new job, select one among those present, change the current job or delete it.
If a job is active, the JOBS MANAGEMENT sub-menu will show four item (Figure 5).
Figure 5
To create and change parameters in a job, see chapter 3.3.
If active, activate the automatic selection of jobs, to select a job other than that automatically
selected, it is necessary to use the unlock password.
4.1 Create a new job
To create a new Job (a memory block of the device) use the following command JOBS MANAGEMENT
> CREATE A NEW JOB and assign a name to it; if the job automatic selection is enabled, see
chapter 4.8. The name of the drawing or the client may be used as names, or any other name to
make it easy to identify the job. If a name is not entered, the job will be named automatically in the
following way: Job 1, Job 2, Job 3, etc.
Figure 6
When a new job is created, the system will ask to name it and then if a copy of the current job is to
be made. If you decide to make a copy of the current job, the job parameters will be duplicated,
while the current job remains unchanged. If a new job is created, it will be empty.
After the job is created, parameters are to be entered, options are to be set and the range has to be
defined.
4.2 Select a job
In the JOBS MANAGEMENT menu, the CHANGE JOB command is displayed. When this command is
selected, the job list is displayed (Figure 7). If a clock is displayed, next to its name, the date and the

14
time of the last change are displayed. It is possible to select a job by using the keys and by
pressing .
Figure 7
If the list is too long, it is possible to press the number keys to skip from an item to another within
the list.
4.3 Edit the job name
To edit the name of the job it is necessary to select it as shown in paragraph 4.2. Once the job that is
to be renamed is selected, show the list of current jobs by using the JOBS MANAGEMENT > CHANGE
JOB command and, after the selected job shows the selection bar, press the key. This way, the
name window will appear.
4.4 Copy a job
To copy a job, select the job to be copied as shown in paragraph 4.2. Once the job to be copied is
selected, create a new job by using the JOBS MANAGEMENT > CREATE A NEW JOB command and
answer YES to the copy question.
4.5 Delete a job
In the JOBS MANAGEMENT menu, the DELETE JOB command is displayed. This command allows to
delete the current job permanently. When a job is deleted, it is necessary to confirm.
4.6 Edit a job
The EDIT JOB menu allows to change all the parameters entered for the job.
To edit the job name, see paragraph 4.3.
In the jobs, all parameters set to zero will be ignored by the device.
4.7 Job counters
Each job is equipped with a piece counter. To access the counter options, select the JOBS
MANAGEMENT > EDIT JOB > COUNT PIECES menu
In this menu it is possible to reset the piece counter to zero and select the maximum number of
scrap pieces that will result in the lock of the device. To unlock the device, use the unlock
password.
4.8 Managing the automatic selection of jobs as an external user
When the automatic selection of job is enabled, Press-Right prepares the selectable jobs. These jobs
are initially empty. To use an empty job, access the JOBS MANAGEMENT > CHANGE JOB menu and
press Enter on the desired job; then select the job name and, if another job was being run, the copy
option is now enabled.

15
It is possible to create additional jobs by using the unlock password.
It is possible to select a job other than the one automatically selected by using the unlock password.
4.9 The graph
In the EDIT JOB menu, the SET GRAPH item is available, allowing for the editing of the graph axes.
Note that it is not possible to edit these values and fully or partly hide the range.
Figure 8
Figure 9

16
As shown in both figures, it is possible to select the following values:
GRAPH ORIGIN
It is the origin value of the horizontal axis of the heights; this parameter allows to hide the
undesired part of the stroke, such as the approach stroke. If the relative heights are used, the
origin is usually set to zero.
HEIGHT FULL SCALE
The height full scale shows the stroke visualized in the graph. The full scale may be selected
from a list.
If, for instance, a 20mm full scale is selected and the origin is set at 33mm, the graph will show
the whole stroke between 33mm and 53mm.
FORCE FULL SCALE
The force full scale shows the maximum force visualized in the graph. The full scale may be
selected from a list.
4.9.1 How to set the graph
After processing a piece, the measured values can be displayed (chapter 8). They are useful to
understand the values of the graph axes.
The origin of the graph can have a value slightly lower that the initial height measured. As the
height full scale enter the value which, being added to the height origin just entered, is higher than
the height measured.
As the force full scale, choose the value greater than the forcer measured.
4.10 Scraps options and management
In the work, in addition to the generic options, there are options for managing of waste and
additional monitor options. Options are accessible from the menu JOBS MANAGEMENT > EDIT JOB
> EDIT PHASE > SCRAP MONITOR OPTIONS that has the following items:
SCRAP MANAGEMENT
It allows the definition of the behavior and the class for each type of scrap material.
OTHER CONTROL MANAGEMENT
This command allows access to the additional monitor management menu, if any (chapter
4.14).
CHANNEL PHASE OPTIONS
This item allows to exclude one or more channels (load cells) if any, and enables the phases to
be executed.
OPTIONS
Job actions may be set here: see chapter 5.4.
4.11 Managing the phases
It is possible to associate more processing phases in a single job. Sub-jobs may be considered,
contributing to the completion of a more complex job (such as inserting the gear bearing on the
shaft).
Assuming that the job above is being executed, it is necessary to:
- enable two phases as follows: JOBS MANAGEMENT > EDIT JOB > EDIT PHASE > SCRAP
MONITORING OPTIONS > CHANNEL PHASE OPTIONS > ENABLE PHASES
- for convenience it is better to display the name of the current phase in the upper line of the
display: TOOLS > DISPLAY MANAGEMENT > CONTRAST AND FEATURES > UPPER LINE
VALUES
Now the desired phase can be selected by using the keys and its parameters may be edited
through the usual job change: JOBS MANAGEMENT > EDIT JOB > EDIT PHASE
Phases will be run automatically in sequence. If you wish to run just regardless of a sequence, select
the command: JOBS MANAGEMENT > EDIT JOB > SELECT PHASE TO RUN

17
A phase may be repeated more than once by entering the number of repetitions in the menu: JOBS
MANAGEMENT > EDIT JOB > EDIT PHASE > SCRAP MONITORING OPTIONS > CHANNEL PHASE
OPTIONS > REPEAT PHASE.
A phase may have a maximum waiting time after which a piece is classified as scrap due to time
elapse. To set th maximum waiting time, go the menu: JOBS MANAGEMENT > EDIT JOB > EDIT
PHASE > PARAMETERS > OTHER PARAMETERS .
4.12 Channel management
This menu is visualized only if multiple load cells are connected.
It is possible to connect up to six force transducers to Press-Right to monitor six motion-force
curves. While a force transducer measures the force in a channel, the position transducer is a single
piece for all channels. It is possible to exclude one of more channels from the monitor by using the
menu JOBS MANAGEMENT > EDIT JOB > CHANGE TAKS > SCRAP AND MONITORING OPTION >
CHANNEL PHASE OPTIONS > CHANNEL EXCLUSION .
Under the graph, the force of a single channel at a time is displayed, using the number keys 1 to 6;
when the menus are not displayed, the current force of each channel may be viewed.
To visualize the curve of some channels, press the key to view the main menu. In this way,
the status of the displayed channels is shown in a top-right box, followed by a 1 to 6 number key.
4.13 Self-verification
The self-verification function is used for periodic inspection of the machine operation by running
the sample pieces prepared deliberately out of tolerance.
This feature is accessible from the menu TOOLS > COUNTERS AND SELF-VERIFICATION > SELF-
VERIFICATION .
The self-verification test can be carried out whenever the device is turned on, whenever the job is
changed, whenever the job is edited, at set times (if he clock is installed), every a set amount of
pieces.
For every job the self-verification function can be excluded.
It is managed by Press-Right as follows: Whenever the device is switched on or the self-verification
is managed by Press-Right as follows: Whenever the device is switched on or every N1 pieces, N2
sample pieces must be processed.
If the device performs further checks in addition to the verification of the force-motion curve, it is
possible to choose whether to execute such monitoring also during the the self-verification
procedure or whether the monitoring is to be run manually after the verification of the force-motion
curve.
It is possible to choose the number of samples to process. By entering zero, the self-verification of
the force-motion curve function is excluded.
4.14 Managing further monitoring
Press-Right can run up to three additional monitoring processes, in addition to the verification of
the curve, to determine whether the piece is good or scrap.
The result of the processing can be affected by the logical status of the three inputs. This logical
status can be monitored at different moments of the process.
For the additional check #1, Press-Right may also activate a port before running an additional
monitoring session and, after a set time, read the input status.
The INPUT TEST SETUP menu allows for the configuration of inputs and assign a descriptive name.
In the JOBS MANAGEMENT > EDIT JOB > CHANGE > OPTIONS AND SCRAP MANAGEMENT >
MANAGEMENT OF OTHER MONITORING SESSIONS menu, it is possible to determine when and how to
perform the additional monitoring sessions. If a port is set up to run the additional check #1, by
using this menu it is possible to manually activate the port.

18
4.14.1 Additional monitoring options
The monitoring options are as follows:
DO NOT RUN THE ADDITIONAL MONITORING SESSION
The additional monitoring session is not performed.
MEASURE AT START
The additional monitoring is carried out when the device receives a STARTcommand.
MEASURE AT SHUTDOWN
The additional monitoring is carried out when the device commands the shutdown and the
piece is good.
MEASURE AT THE END
The additional monitoring is carried out when the press is back to position.
MEASURE AT A SPECIFIC HEIGHT
The additional monitoring is carried out at a set height by means of the HEIGHT MEASURE
parameter in the ADDITIONAL MONITORING MANAGEMENT menu.
MEASURE FROM A SPECIFIC HEIGHT
The additional monitor is carried out starting from a set height by means of the HEIGHT
MEASURE parameter in the ADDITIONAL MONITORING MANAGEMENT menu until the end of the
production process.
MEASURE UP TO A SPECIFIC HEIGHT
The additional monitoring session is carried out starting when the device receives the START
command up to a set height, by means of the MEASURE HEIGHT parameter of the ADDITIONAL
MONITORING MANAGEMENT menu.
MEASURE DURING
The additional monitorinf is maintained throughout the whole process.

19
5 Parameters
In the jobs, all parameters set to zero will be ignored by the device.
5.1 Motion management
Once a new job is created, define the motion parameters: JOBS MANAGEMENT > EDIT JOB >
CHANGE JOB > PARAMETERS > MOTION MANAGEMENT. In this sub-menu, the motion parameters
may be set as already described in chapter 3.2
5.2 Limits and thresholds
The limits, along with the range, determine the result of the job.
You can set the limits of maximum force, the limits of maximum height, the limits of initial height
and speed.
Note: The limits and thresholds set equal to zero, are not used.
FORCE LIMITS
They monitor the force reached during processing. In order for a piece to be classified as good,
the maximum force reached should be greater than the minimum force and lower than the
maximum force. To set the force limits, use the command EDIT JOB > CHANGE JOB >
PARAMETERS > FORCE LIMITS .
INITIAL FORCE
The initial force is the force threshold used to measure the initial height. The initial height is
described in chapter 1.3.1. To set the initial force, use the command EDIT JOB > CHANGE JOB
> PARAMETERS > FORCE LIMITS .
HEIGHT LIMITS
They monitor the maximum height reached during processing. In order for a piece to be
classified as good, the maximum height should be greater than the minimum height and lower
than the maximum height. If there is no minimum height limit and the range is not reached by
the curve, the piece is classified as scrap due to minimum height. To set the height limits, use
the command EDIT JOB > CHANGE JOB > PARAMETERS > HEIGHT LIMITS .
INITIAL HEIGHT LIMITS
They monitor the initial processing height. In order for a piece to be classified as good, the
initial height should be greater than the minimum initial height and lower than the maximum
initial height. To set the initial height limits, use the command EDIT JOB > CHANGE JOB >
PARAMETERS > HEIGHT LIMITS . The initial height is described in chapter 1.3.1.

20
5.2.1 How to choose the limits
The initial height limits allow to monitor the dimensions of the components before they are
processed. They may be useful to monitor the dimensions of the pieces to assemble or to monitor
whether all components necessary for the processing are present.
The selection mode of the limits which monitors the maximum force and height reached, also in this
case, by the type of production.
5.2.1.1 Limits during the production (mechanical stop enabled)
When the mechanical stop process is selected, the press will always reach either the shutdown force
or the maximum force to be exerted. For this reason, the force limits are simply used to monitor the
shutdown force (minimum force limit) and to make sure that the maximum force that the piece
being processed can bear, is not exceeded (maximum force limit).
In order to monitor the actual force necessary for processing, the range must be used.
The height limits are used to make sure that the assembly dimensions are within tolerance range, at
the end of the processing.
5.2.1.2 Limits during the production (mechanical stop not enabled)
In this case the force limits are not very useful unless you wish to monitor whether the maximum
force supported by the piece being processed, is not exceeded. On the other hand, the height limits
are necessary to monitor whether the height reached is indeed the force requested. A shutdown
height lower than the minimum required limit is often set and used to monitor the actual height
reached.
5.2.1.3 Limits for bending and breaking tests
During the bending test the force limits are used simply to monitor the force exerted, while the
height limits are used to monitor the bending.
During the breaking tests, only the force limits are used to monitor the force necessary to break the
piece.
5.3 Check points
It is possible to enter five verification elements based of the following types:
The software filter of the force measured (speed measure check point)
Measure of the minimum and maximum force value between two height values and the monitor the
maximum difference (minimum maximum measure check point).
Measure and monitor of the curve slope within the height interval (slope monitor check point)
Force monitor at a specific height (force verification check point)
Height monitor at a specific force (height verification check point)
The tool can manage up to three digital ports which may be activated at programmable heights
(check point out check point)
5.4 Job options
The following job options may be modified by using the JOBS MANAGEMENT > EDIT JOB > EDIT
PHASE > OPZION AND OTHER MONITORING SESSIONS > OPTIONS .
USE RELATIVE HEIGHTS
By activating this option, relative heights are used instead of absolute heights (chapter 1.3.1).
REQUEST PIECE CODE
By activating this option, before the execution of each piece the system will request to enter a
number code that identifies the piece. This code is used by the WinScope software to store the
curve and the values measured.
IGNORE PERMISSIONS 1 2 3
Do not affect the start of the logic status of such ports (if set up).
