1 SAFETY INSTRUCTIONS

IMPORTANT SYMBOLS



This symbol indicates important information and instructions.

Caution! This symbol indicates a potentially dangerous situation. If it is not avoided, slight or minor injuries may result.

Danger! This symbol indicates an immediate hazard. If it is not avoided, death or serious injuries may result.

GENERAL SAFETY INSTRUCTIONS

 These operating instructions contain important information on using the ejector. Please

read the operating instructions thoroughly and keep them for later reference.

Never look into any open or closed vacuum vents (e.g. vacuum connections or suction pads). Serious injuries could occur as a result. Eyes can be sucked in.

 Compressed air can cause closed containers to explode. A vacuum can cause closed

containers to implode.

 The ejector may only be operated with a silencer. Never look into the exhaust air jet of

the silencer.

 The ejector emits noise. We recommend wearing ear protection.  This device is not intended for use with hazardous dust, oil mist, vapors or aerosols,

etc. If drawn in, these materials will enter the exhaust air and may result in poisoning.

 Use only the connections, mounting holes and attachment materials that have been

provided.

 Carry out mounting and removal only when the device is in an idle, depressurized state.  No person may sit or stand in the area in which the load is to be transported.  No person may sit or stand in the danger zone while the machine or system is in auto-

matic mode.

 Components may be installed by trained specialist personnel only.

Page 6

 Specialist personnel must be familiar with current safety rules and requirements. For

example, these apply to the use of components such as solenoid valves and pressure switches as well as to controllers used in devices, machines and systems.

 Specialist personnel must also be familiar with the system’s control concept. In particu-

lar, they must be familiar with the system’s redundant control components and feed-

back signals.

INTENDED USE

The ejector is designed to generate a vacuum for gripping and transporting objects when used in conjunction with suction pads. Neutral gases in accordance with EN 983 are approved as evacuation media. Neutral gases include air, nitrogen and inert gases (e.g. argon, helium and neon). Aggressive gases or media such as acids, acid fumes, bases, biocides, disinfectants or detergents are not permitted.

The ejector is not suitable for transporting or sucking through liquids or bulk material such as granulates. Personal injury or damage to the ejector may occur.

INSTALLATION AND OPERATION

For safe installation and trouble-free operation, please observe and comply with the following points:

The ejector may only be operated using power supply units with protected extra-low voltage (PELV). The system must incorporate safe electrical cutoff of the power supply in compliance with EN60204.

Do not operate the ejector in environments where there is a risk of explosion. Risk of fire and explosion.

Output signals (discrete signals as well as IO-Link signals) can change when the power supply is switched on or the M12 connectors are plugged in. Depending on the function of the machine/system, this can result in serious personal injury or damage to the equipment.

The device may not be operated outside its specified performance limits. Doing so may cause it to malfunction or be destroyed.

During installation and maintenance, make sure that the ejector is disconnected and depressurized and that it cannot be switched on again without authorization. Personal injury or damage to the ejector may occur.

 Protect the ejector from damage at all times.  No modifications may be made to the ejector.  Opening the ejector will damage the “tested” labels. This voids the warranty.  Connection symbols and labels are located on the ejector.

These must be observed.

 Only the intended connections may be used.  Pneumatic and electrical line connections must be securely connected and attached to

the ejector.

 The ejector may be installed in any position.  If these instructions are not observed, malfunctions, material damage and serious injury

– including fatal injury – may result.

 If the ejector is no longer operative, the components must be disposed of in an ecologi-

cally sound manner.

2 PRODUCT OVERVIEW

GENERAL DESCRIPTION OF FUNCTIONS

VACUUM GENERATION (PICKING UP THE WORKPIECE)

The ejector is designed for vacuum handling of parts in combination with suction systems. The Venturi nozzle is activated and deactivated via the suction signal input. In the NO ver-

sion, the Venturi nozzle is deactivated when the suction input signal is present. In the NC version, the Venturi nozzle is activated when the suction input signal is present.

An integrated sensor records the vacuum generated by the Venturi nozzle. This is evaluated by an electronics system and appears on the display. The measured value serves as the basis for the air saving function, switching the output and the many analysis functions of the energy process control system.

The ejector has an integrated air-saving function. The ejector automatically regulates the vacuum while in suction mode. The electronics system switches the Venturi nozzle off when the switching point H1 set by the user is reached.



If small volumes are to be evacuated, the set switching point H1 might be exceeded considerably before the vacuum is switched off. This system behavior does not constitute an error.

When objects with dense surfaces are picked up, the integrated non-return valve prevents the vacuum from dropping. If leakage causes the system vacuum to drop below the switching point H1-h1, the Venturi nozzle is switched on again.

The supply voltage is monitored by the electronics system. If the supply voltage falls below approx. 19.2 V, this is indicated by an error message. It cannot be ensured that the ejector will operate as intended below this voltage threshold.

The supply voltage’s maximum permitted upper limit of approx. 26.4 V is also monitored. The display will indicate any value in excess of this limit.

BLOW-OFF (DEPOSITING THE WORKPIECE)

In blow-off mode, the vacuum circuit of the ejector is supplied with compressed air. This ensures that the vacuum drops quickly, depositing the workpiece quickly as well. Blow-off mode can be controlled externally or internally.

When controlled externally, blow-off mode is activated by the “blow-off” signal input. When controlled internally (automatic blow-off), the blow-off valve is actuated for a defined

period after suction mode is exited. With the externally controlled automatic blow-off, the “Blow-off” valve is activated for a set

amount of time once the “Blow-off” signal input is received.



The ejector also has a manual mode. In this mode, suction and blow-off can be

controlled using the keys on the ejector’s foil keypad. See the “Manual mode”

section for more details.

IO-LINK

The ejector can be operated in IO-Link mode to enable intelligent communication with a controller.

The ejector’s parameters can be set remotely using IO-Link mode. The energy and process control (EPC) function is also available in IO-Link mode.

Energy and process control (EPC) is divided into 3 modules:

 Condition monitoring (CM): Condition monitoring to increase system availability  Energy monitoring (EM): Energy monitoring to optimize the vacuum system’s energy

consumption

 Predictive maintenance (PM): Predictive maintenance to increase the performance and

quality of the gripper systems

3 DESCRIPTION OF FUNCTIONS

OPERATING MODES

The ejectors are differentiated according to their start position when in the idle state: NO (normally open) and NC (normally closed).

When the ejector is connected to the power supply, the ejector is in automatic mode and ready for operation. This is the normal operating mode, in which the ejector is operated by the system controller. A differentiation is made between SIO mode and IO-Link mode.

In addition to automatic mode, you can also use the keys on the ejector to switch to manual mode using the buttons on the foil keypad.

Parameterization of the ejector is always performed in automatic mode.

GENERAL FUNCTIONS

MANUAL MODE

The output signals may change during set-up in manual mode. Ensure that the machine or system does not start moving as a result. Personal injury or damage to the ejector could result.

In manual mode, the “Suction” and “Blow-off” ejector functions can be controlled independently of the higher-level controller using the buttons on the operating panel.

In this operating mode, the H1 and H2 LEDs both flash. Because the valve protection function is deactivated in manual mode, this function can be

used to locate and rectify leaks in the vacuum circuit.

ACTIVATING MANUAL MODE

Activate manual mode as follows:

 Press and hold the and buttons together for more than 3 seconds.

During activation, [-M-] will appear.

When manual mode is activated, the current process state will initially be maintained.

MANUAL SUCTION

In manual mode, suction is activated by pressing the button. Exit suction mode by pressing the

button again or by pressing the button.



If the air-saving function is activated ([ctr=on] or [ctr=ONS]), this is also activated in manual mode.



The valve protection function is not active in manual mode.

MANUAL BLOW-OFF

Blow-off mode is activated in manual mode by pressing the button. This mode remains active as long as the button is pressed.

DEACTIVATING MANUAL MODE

Press the key to exit manual mode. The operating mode will also be exited if the status of the external signal inputs changes.

This automatic exiting of manual mode due to changes in external signals can cause the object being handled to move (due to suction or blow-off).

Page 18

SCHMALZ SCPSI - 2

3-18

SET-UP MODE

Similar to manual mode, set-up mode can be used to locate and rectify leaks in the vacuum circuit because the valve protection function is deactivated and because the control function is not deactivated even if the control frequency increases.

In this operating mode, the H1 and H2 LEDs both flash. Setup mode is switched on and off using the process data output (PDO). The suction and

blow-off process bits always have priority.



This function is only available in IO-Link mode.

MONITORING THE SYSTEM VACUUM

Every ejector has an integrated sensor for monitoring the current system vacuum. The vacuum level provides information on the process and has an effect on the following signals and parameters:

 Threshold value LED H1  Threshold value LED H2  Signal output H2  Vacuum analog value  Process data bits H1  Process data bits H2

The threshold values and the corresponding hysteresis values can be set under the menu items [H-1], [h-1], [H-2] and [h-2] or via IO-Link.

ZERO-POINT ADJUSTMENT OF THE SENSOR (CALIBRATION)

Because the production conditions for the internally integrated sensor can vary, we recommend calibrating the sensor once it is installed in the ejector.

The pressure circuit of the system must be ventilated to ambient pressure before a zeropoint adjustment can be made to the pressure sensor.



The zero point can only be shifted within a range of 3% from the end value of the measurement range.



If the permissible limit of 3% is exceeded, the [E3] error code is shown in the display.

The function for zero-point adjustment of the sensor is performed in the basic menu under

[CAL] or using IO-Link.

Page 19

SCHMALZ SCPSI - 2

3-19

CONTROL FUNCTION

With this function, the ejector allows you to save compressed air or prevent a too powerful vacuum from being generated. Vacuum generation is interrupted once the configured threshold value H1 is reached. If leakage causes the vacuum to fall below the hysteresis threshold H1-h1, vacuum generation resumes.

The following operating modes can be set for the control function in the configuration menu under the [ctr] menu item or via IO-Link.

NO CONTROL (CONTINUOUS SUCTION)

The ejector produces continuous suction with maximum power. This setting is recommended for very porous workpieces, which would otherwise cause the vacuum generator to switch on and off continually due to the high rate of leakage.

The control function setting for this operating mode is [oFF].



This setting ([ctr = oFF]) is only possible when control shutoff is deactivated

[dCS = oFF].

CONTROL

The ejector switches off the vacuum generator when the threshold H1 is reached and switches it back on when the vacuum falls below the threshold H1-h1. This setting is particularly recommended for suction-tight workpieces.

The control function setting for this operating mode is [on].

CONTROL WITH LEAK MONITORING

This operating mode is the same as the previous mode, with the addition that the leakage rate within the system is measured and compared to the configurable limit value [-L-]. If

the actual leakage rate exceeds the limit value more than twice in succession, the control function is deactivated and the ejector switches to continuous suction.

In this mode, the control function should be set to [onS]



When the [onS] function is activated, [-L-] is activated in the configuration menu.

DEACTIVATING THE CONTROL SHUTOFF FUNCTION

With this function, the automatic control shutoff caused by condition monitoring functions can be deactivated.

The function can be set in the configuration menu under the [dCS] menu item or via IOLink.

Page 20

SCHMALZ SCPSI - 2

3-20

If the function [dCS = oFF] is selected, the ejector switches to continuous suction mode if the leakage rate and the valve switching frequency are too high.

With the [dCS = on] setting, continuous suction is deactivated and the ejector continues in control mode despite high leakage and a control frequency greater than 6/3 s.

If the control shutoff function is deactivated [dCS = on], the suction valve may be switched very frequently.

This can destroy the ejector.



The setting [dCS = on] is only possible when the control function

[ctr = on] or [ctr = onS] is set.



In cases of undervoltage or power failure, the ejector switches to continuous suction according to the particular ejector version (NO/NC/IMP), even if conti-

nuous suction was deactivated with the [dCS = on] setting.

BLOW-OFF MODES

This function is used to switch among the three blow-off modes. The function can be set in the configuration menu under the [bLo] menu item or via IO-

Link.

EXTERNALLY CONTROLLED BLOW-OFF

The blow-off valve is controlled directly via the blow-off signal input. The ejector switches to blow-off mode for as long as the signal is present.

The blow-off function setting for this operating mode is [-E-].

INTERNALLY TIME-CONTROLLED BLOW-OFF

The blow-off valve is controlled automatically for the time period [tbL] after the ejector exits suction mode. This function makes it possible to save an output on the controller.

The blow-off function setting for this operating mode is [I-t].



The “Blow-off” mode can still be activated in [I-t] mode using the “Blow-off” signal input.

EXTERNALLY TIME-CONTROLLED BLOW-OFF

The blow-off pulse is controlled externally via the blow-off input. The blow-off valve is controlled for the configured time [tbL]. A longer input signal does not increase the blow-off

duration. The blow-off function setting for this operating mode is [E-t].

Page 21

SCHMALZ SCPSI - 2

3-21



The length of the blow-off time [tbL] is set in the main menu. This menu item is hidden in the [-E-] operating mode.



The number displayed indicates the blow-off time in seconds. Blow-off times from 0.10 s to 9.99 s can be set.

SIGNAL OUTPUT

The ejector has a signal output. The signal output can be configured using the corresponding menu item.

OUTPUT FUNCTION

The signal output can be switched between [no] (normally open) and [nc] (normally closed).

You can switch it in the configuration menu using the [o-2] menu item, or set it using the IO-Link.

The function of the switching threshold H2/h2 (component check) is assigned to the OUT 2 signal output.

OUTPUT TYPE

The output type can be used to switch between PNP and NPN. The signal inputs are also configured with this function.

The outputs/inputs can be switched using the [tYP] menu item in the configuration menu, or via IO-Link.

SELECTING THE VACUUM UNIT

This function can be used to select the units for the displayed vacuum values from the following three units.

The function can be set in the configuration menu under the [uni] menu item or via IOLink.

BAR

The vacuum values are displayed in mbar. The setting for these units is [-bA].

PASCAL

The vacuum values are displayed in kPa. The setting for these units is [-PA].

Page 22

SCHMALZ SCPSI - 2

3-22

INCH OF HG

The vacuum values are displayed in inHg. The setting for this unit is [-iH].

The function can be set using the configuration menu under the menu item [uni] or can be set via IO-Link.



Selection of the vacuum unit only affects the display of the ejector. The units of the parameters that can be accessed via IO-Link are not affected by this setting.

SWITCH-OFF DELAY OF THE H2 COMPONENT CHECK SIGNAL

You can use this function to set a switch-off delay for the H2 component check signal. This can be used to handle short drops in the vacuum circuit.

The length of the switch-off delay is set for both outputs together via the [dlY] menu item in the configuration menu or via IO-Link. Values of 10, 50 or 200 ms can be selected; a value of 0 (= off) must be set to deactivate this function.



The switch-off delay affects the OUT2 discrete output, the process data bit in IOLink and the H2 status display



If the OUT2 output is configured as a normally open contact [no], there will be an electrical switch-off delay. On the other hand, if it is configured as a normally

closed contact [nc], there will be an equivalent switch-on delay.

ECO-MODE

The ejector offers the option to switch off the display to save energy. If eco mode is activated, the display is switched off and the power consumption is reduced after 2 minutes if no buttons are pressed.

A red dot in the lower right corner of the display indicates that the display has been switched off. The display can be reactivated by pressing any key. The display will also be reactivated if there is an error message.

ECO mode can be activated and deactivated in the configuration menu under the [Eco] menu item or via IO-Link.



If you activate ECO mode using IO-Link, the display will immediately enter energy-saving mode.

PIN FOR WRITE PROTECTION

A PIN code can be used to prevent the parameters from being changed using the user menu. The current settings are still displayed.

The PIN is set to 000 on delivery, meaning access to the parameters is not locked. A valid PIN between 001 and 999 must be entered in order to activate the write protection.

If write protection is activated with a customer-specific PIN, the desired parameters can be changed within one minute after the correct code is entered. If no changes are made within one minute, write protection is automatically reactivated. A PIN of 000 must be set to permanently deactivate the lock.

Full access is still possible via IO-Link even if a PIN is enabled. The current PIN can also be read out and changed/deleted (PIN = 000) via IO-Link.

The PIN is entered in the configuration menu under the menu item [PIN] or via IO-Link.

A PIN is recommended because carrying out parameterization while the ejector is in operation can change the status of signal inputs and outputs.

WRITE PROTECTION WITH DEVICE ACCESS LOCKS

In IO-Link mode, the “Device Access Locks” default parameter is available to prevent changes to other parameter values using the user menu or IO-Link.

You can also prevent use of the data storage mechanism described in IO-Link Standard V1.1.

RESET TO FACTORY SETTINGS

This function restores the ejector configurations of the initial setup and the settings of the active production setup profile to the factory settings.

This function does not affect counter readings, the zero-point adjustment of the sensor or the “Application Specific Tag” IO-Link parameter.

The function is carried out in the configuration menu under the [rES] menu item or via IOLink.



The factory settings of the ejector can be found in the appendix.



The function for restoring the factory settings does not affect the currently inactive production setup profiles.

Restoring the factory settings will change the switching points and the configuration of the signal output. This can change the status of the ejector system.

COUNTER

The ejector has two internal counters that cannot be deleted: [cc1] and [cc2].

Counter 1 increases with each valid pulse at the “Suction” signal input, meaning that it

counts all the suction cycles during the ejector’s service life. Counter 2 increases each ti- me the “Suction” valve is switched on. As a result, the average switching frequency of the

air saving function can be determined using the difference between counters 1 and 2.

VOLTAGE MONITORING

All ejector types have an internal voltage monitor. If the supply voltage falls below the permitted threshold, the ejector has the E07 error status. This appears in the display, and prevents menu operation and response to the signal inputs. The component check output

retains its normal functionality. The current supply voltage can still be viewed using the key.

The pneumatic state of the ejector changes as follows:

NO EJECTOR TYPE

The ejector switches to „Suction“ mode

NC EJECTOR TYPE

The ejector switches to “Pneumatically OFF” mode



The control function is canceled if the voltage drops while suction is active.

In addition, an excessive supply voltage will be detected and a corresponding error message will be generated.

EVALUATING THE INLET PRESSURE

The supply pressure level in the system cannot be measured by the ejector itself. However, it is possible to send the current measured value of the inlet pressure from the system controller to the device via IO-Link.

In this case, the ejector evaluates the pressure value and activates a condition monitoring warning if the value is not optimal. If the pressure is considerably too low or too high, an error message is also generated.

A pressure value must also be transferred to enable an estimate of the volume of compressed air consumed in the suction cycle to be made in the area of energy monitoring.

SETTING THE BLOW-OFF VOLUME FLOW

There is a valve screw below the vacuum connection (2). This valve screw can be used to set the blow-off volume flow.

Turning the screw clockwise reduces the volume flow. Turning the screw counterclockwise increases the volume flow.

The valve screw is equipped with a stop on both sides.

Do not turn the valve screw past the stops. A minimum volume flow of approx. 10% is always necessary for technical reasons.

The blow-off volume flow can be set between 10% and 100%.

PRODUCTION SETUP-PROFILES



Additional functions in IO-Link mode: The functions described below are only available in IO-Link mode

The ejector can store up to four different production setup profiles (P-0 to P-3). All important data for workpiece handling is stored in these profiles. The profiles are selected using the PDO byte 0 process data byte. This gives users a quick, convenient option for adjusting the parameters to different workpiece properties.

The currently selected data set is displayed in the parameter data under “Production

Setup”. These are also the current parameters the ejector is working with, which can be

viewed using the menu.



If you select the basic menu by pressing , the parameter data set currently being used will appear briefly in IO-Link mode.



In the default setting and in SIO mode, the P-0 production setup profile is selected.

CONDITION MONITORING [CM]



Additional functions in IO-Link mode: The functions described below are only available in IO-Link mode

MONITORING THE VALVE SWITCHING FREQUENCY

If the air-saving function is activated ([ctr = on] or [ctr = onS]) and the leakage rate in

the gripper system is high, the ejector is constantly switching between the “Venturi nozzle active” and “Venturi nozzle inactive” states. The number of valve switching procedures

thus increases rapidly within a short time. In order to protect the ejector and increase its service life, the ejector switches the air-saving function off automatically at a switching frequency of > 6/3 seconds and activates continuous suction (i.e., the ejector then remains in the “Venturi nozzle active” state).

The basic monitoring of valve protection function is also active in the SIO mode.

In IO-Link mode, the appropriate condition monitoring warning is also set. In addition, thesystem status light switches to yellow.



The [dCS = ON] setting prevents continuous suction.

MONITORING THE CONTROL THRESHOLD

If the switching point H1 is never reached during the suction cycle, the “H1 not reached”

condition monitoring warning will be triggered and the system status light will switch to yellow.

This warning is available at the end of the current suction phase and remains active until the next suction cycle.

Page 28

SCHMALZ SCPSI - 2

3-28

MONITORING THE EVACUATION TIME

If the measured evacuation time t1 (from H2 to H1) exceeds the specified value

[t-1], the “Evacuation time longer than t-1” condition monitoring warning will be triggered

and the system status light will switch to yellow. The specified value for the max. permitted evacuation time can be set in the configuration menu under [t-1] or using IO-Link. Setting the value to 0 (= off) deactivates monitoring.

The maximum permitted evacuation time setting is 9.99 s.

MONITORING LEAKAGE

In control mode (ctr = onS), the drop in the vacuum level within a certain time is monitored (mbar/s). A distinction is made between two states.

Leckage L < [-L-]

Leckage L > [-L-]

If the leakage rate is less than the set value

[-L-] in mbar/s, the vacuum level continues

to fall until the switching point H1-h1 and then the ejector resumes suction (normal control mode).

The condition monitoring warning is not activated and there is no effect on the system status light.

If the leakage rate is greater than the value

[-L-], the ejector immediately reacts to cor-

rect the vacuum level. If the permitted leakage is exceeded twice,

the ejector switches to continuous suction. The condition monitoring warning is acti-

vated and the system status light switches to yellow.



The [dCS = ON] setting prevents continuous suction.

MONITORING THE DYNAMIC PRESSURE

If possible, a dynamic pressure measurement is taken at the start of every suction cycle. The result of this measurement is compared to the threshold values set for H1 and H2.

If the dynamic pressure is greater than (H2 – h2) but less than H1, the corresponding condition monitoring warning will be set and the system status light will switch to yellow.

EVALUATING THE LEAKAGE LEVEL

This function determines the average leakage during the last suction cycle, divides it into subareas and makes it available as a parameter via IO-Link.

MEASUREMENT OF THE EVACUATION TIME t0

This measures the time (in ms) from the beginning of a suction cycle, started by the command “Suction ON”, until the switching threshold H2 is reached.

MEASUREMENT OF THE EVACUATION TIME t1

This measures the time (in ms) from when the switching threshold H2 is reached until the switching threshold H1 is reached.

ENERGY MONITORING [EM]



Additional functions in IO-Link mode: The functions described below are only available in IO-Link mode

The ejector offers functions for measuring and displaying the energy consumption to help further optimize the energy efficiency of vacuum gripper systems.



The values are determined from comparison tables according to current process parameters. Although the ejector is not a calibrated measuring devices, the values can be used as a reference and for relative measurements.

PERCENTUAL AIR CONSUMPTION MEASUREMENT

All ejectors calculate the percentual air consumption of the last suction cycle. This value corresponds to the ratio of the active suction/blow-off times to the total duration of the suction cycle.

ABSOLUTE AIR CONSUMPTION MEASUREMENT

An externally recorded pressure value can supplied using the IO-Link process data. If this value is available, not only a percentage-based air consumption measurement, but also an absolute air consumption measurement can be performed.

The actual air consumption of a suction cycle is calculated by taking into account the system pressure and the nozzle size.



An absolute air consumption measurement can only be made using a pressure value supplied externally via IO-Link.

ENERGY CONSUMPTION MEASUREMENT

The ejector determines the electrical energy consumed during a suction cycle, including the energy it consumes itself and the energy consumed by the valve coils.

SCHMALZ SCPSI - 2

PREDICTIVE MAINTENANCE [PM]



Additional functions in IO-Link mode: The functions described below are only available in IO-Link mode

For early detection of wear and other impairments to the vacuum gripper system, the ejector features functions for detecting trends in the system’s quality and performance. Leakage and dynamic pressure are measured for this purpose.

MEASUREMENT OF THE LEAKAGE

This measures the leakage (drop in vacuum level per unit of time in mbar/s) after the control function has halted suction because the threshold value H1 was reached.

MEASUREMENT OF THE DYNAMIC PRESSURE

This measures the system vacuum achieved during unobstructed intake. The duration of the measurement is approx. 1 s. To perform a valid dynamic pressure value evaluation, it is therefore necessary to allow the ejector to suck in air unobstructed for at least 1 s after suction begins, i.e., the suction cell must not yet be covered by a component.

Measured values that are above the threshold value H1 are output as 0 mbar to indicate that a valid dynamic pressure measurement could not be performed.

Measured values that are greater than the threshold value (H2 – h2) but less than the threshold value H1 trigger a condition monitoring event.

QUALITY ASSESSMENT

To evaluate the entire gripper system, the ejector calculates a quality assessment value based on the measured leakage in the system.

The greater the leakage in the system, the poorer the quality of the gripper system. Accordingly, low leakage leads to a high quality assessment value.

PERFORMANCE CALCULATION

Similar to the quality assessment, the performance calculation is used to assess the system state. The measured dynamic pressure can be used as a measure of the performance of the gripper system.

Optimally designed gripper systems lead to low dynamic pressures and thus high performance; poorly designed systems result in low performance values.

Dynamic pressure measurements that are greater than the threshold value (H2– h2) always result in a performance rating of 0%. A performance rating of 0% is also issued for a dynamic pressure of 0 mbar (which serves as an indication that the measurement was not valid).

DIAGNOSTIC BUFFER

The condition monitoring warnings described above and the general error messages from the device are saved in a diagnostic buffer.

The content of this memory is made up of the last 38 events, starting with the most recent, and can be read out via an IO-Link parameter. For each event, the current reading of the suction cycle counter cc1 is also saved to allow subsequent temporal assignment of the events to other processes in the system. See the associated IO-Link Data Dictionary for the actual data display of the diagnostic buffer.

The recording of these events is also active in SIO mode and the contents of the memory is retained after a power failure. The memory is deleted manually using the IO-Link system command “Clear diagnostic buffer” or also by restoring the factory settings on the device.

EPC DATA BUFFER

The ejector provides a ten-stage data buffer to enable long-term monitoring and trend analysis of the most important key figures in a handling process. The current measurement values for the evacuation time t1, the leakage rate and the dynamic pressure (vacuum during unobstructed intake) determined during the suction cycle can be saved in this buffer.

The values are saved automatically, always together with the execution of the Autoset function in condition monitoring described above. For each data record, the current reading of the suction cycle counter cc1 is also saved to allow subsequent temporal assignment to other processes in the system. The contents of the EPC data buffer can be read out via an IO-Link parameter. See the associated IO-Link Data Dictionary for the actual data display of this buffer. The contents of the memory remains intact after a power failure.

4 OPERATING AND MENU CONCEPTS

The unit is operated via four buttons on the foil keypad. Settings are made using software menus. The operating structure is divided into settings in the main menu and in the configuration menu. Configuring the ejector in the main menu is sufficient for standard applications. An extended configuration menu is available for applications with special requirements.

If settings are changed, this can cause undefined changes to the system status for a shot period of time (approx. 50 ms) in certain situations.

VACUUM DISPLAY

The ejector is in display mode when the menus are not being accessed. The current vacuum or the current system pressure is displayed.

If there is overpressure in the suction circuit, this is indicated by the ejector with the display “-FF”. This normally always happens in blow-off mode.

An excessive vacuum value (outside of the measurement range) is indicated by the display“FFF”.

5 OPERATING MODE

All ejectors of the SCPSi series have two operating modes. Users can choose between direct connection to inputs and outputs (serial I/O = SIO mode) or connection through the communication line (IO-Link).

By default, the ejector always runs in SIO mode, but it can be switched in and out of IOLink mode by an IO-Link master at any time.

SIO OPERATING MODE

OVERVIEW

When the ejector is operated in SIO mode, all signal inputs and outputs are connected to a controller either directly or via intelligent connection boxes.

In addition to the power supply connection, this mode requires two signal inputs and one signal output, via which the ejector communicates with the controller.

This means that the ejector’s basic suction and blow-off functions, as well as the “Component check” feedback function, can be used.

Ejector inputs

Ejector output

 Suction ON/OFF

 Blow-off ON/OFF

 Feedback H2 (component check)

The “Blow-off” signal does not have to be used if the ejector is operated with internal time control in blow-off mode. This allows operation on a single port in a configurable terminal box (using 1xDO and 1xDI).

The parameters are set and the internal counters are read exclusively via the operating and display elements.

Neither the condition monitoring (CM) events, nor the energy monitoring (EM) and predictive maintenance (PM) functions are available in SIO mode.

PNEUMATIC CONNECTION

 Use only well-maintained compressed air (air or neutral gas according to EN 983, fil-

tered to 5 µm, oiled or unoiled).

 High-quality compressed air is important to ensure a long service life for the ejector.  Dirt particles or foreign bodies in the ejector connections, hoses or pipelines can lead to

partial or complete ejector malfunction.

 Hoses and pipelines should be laid such that distances are minimized.  If the internal diameter on the compressed air side is too small, insufficient compressed

air will be supplied. This prevents the ejector from performing as specified in the performance data.

 Excessive flow resistance occurs if the internal diameter on the vacuum side is too

small. This leads to both a reduction in suction capacity and increased evacuation times. Blow-off times are also lengthened.

 Hose lines must be laid without bends or crimps.  Only use hoses or pipes with the internal diameters recommended for the ejector. If this

is not possible, use the next largest internal diameter.

IO-LINK MODE

OVERVIEW

When operating the ejector in IO-Link mode (digital communication), only the power supply and the communication line must be connected to a controller directly or via intelligent connection boxes.

The communication line for IO-Link (C/Q line) must always be connected to an IO-Link master port (point-to-point connection). It is not possible to connect multiple C/Q lines to only one IO-Link master port.

When the ejector is connected via IO-Link, a number of additional functions are available beyond the basic functions of the ejector (suction, blow-off, feedback signals, etc.). This includes but is not limited to:

 Current vacuum and pressure value  Selection of four production profiles  Errors and warnings  Ejector system status display  Access to all parameters  Counters  Condition monitoring  Energy monitoring  Predictive Maintenance

In this mode, all adjustable parameters can be read, changed and written to the ejector directly using the higher-level controller.

The condition and energy monitoring results can be evaluated to produce trend analyses and to provide direct information on the current handling cycle.

The ejector supports the IO-Link revision 1.1 with four bytes of input data and two bytes of output data.

It is also compatible with IO-Link masters that use the 1.0 revision. In this case, one byte of input data and one byte of output data are supported.

The exchange of process data between the IO-Link master and the ejector is cyclical. Parameter data (acyclical data) is exchanged by the user program in the controller using communication modules.

PNEUMATIC CONNECTION

 Use only well-maintained compressed air (air or neutral gas according to EN 983, fil-

tered to 5 µm, oiled or unoiled).

 High-quality compressed air is important to ensure a long service life for the ejector.  Dirt particles or foreign bodies in the ejector connections, hoses or pipelines can lead to

partial or complete ejector malfunction.

 Hoses and pipelines should be laid such that distances are minimized.  If the internal diameter on the compressed air side is too small, insufficient compressed

air will be supplied. This prevents the ejector from performing as specified in the performance data.

 Excessive flow resistance occurs if the internal diameter on the vacuum side is too

small. This leads to both a reduction in suction capacity and increased evacuation times. Blow-off times are also lengthened.

 Hose lines must be laid without bends or crimps.  Only use hoses or pipes with the internal diameters recommended for the ejector. If this

is not possible, use the next largest internal diameter.

The system may only be operated using power supply units with protected extra-low voltage (PELV) and safe electrical cut-off of the operating voltage, in accordance with EN60204.

Do not forcibly connect or disconnect plug connectors.

PROJECT PLANNING

To operate the ejector in IO-Link mode, you only need to connect an IO-Link connection line (C/Q) in addition to the power supply. Each ejector therefore only requires one line for all process and parameter data.

The ports on an IO-Link master typically have to be switched to IO-Link mode first. This is done using the configuration tool supplied by the manufacturer of the master or controller. The port can be configured generically for IO-Link by entering the correct process data length for the IO-Link device and possibly also storing standard settings for the required manufacturer ID and device ID in the master.

Alternatively, the electronic device description file, or IODD, can be used. To do this, an IO-Link configuration tool from the master manufacturer must be available into which the IODD is imported. This kind of tool displays all process and parameter data for the device in a meaningful format and enables convenient offline parameterization or also observation during operation.

Page 52

SCHMALZ SCPSI - 2

5-52

For the devices in the SCPSi series, the IODD is available to download in two versions from www.schmalz.com:

 IODD in accordance with the revision 1.1, for use with current IO-Link masters The full

range of functions is available with 4 bytes of input data and 2 bytes of output data

 IODD in accordance with the revision 1.0, for use with older IO-Link masters (legacy

mode). The range of functions is slightly limited; the process data is limited to 1 byte of input data and 1 byte of output data.

For example, when using Siemens components, the IODD for the ejector is displayed as follows in the program S7-PCT.

Page 53

SCHMALZ SCPSI - 2

5-53

PROCESS DATA

Once communication with an IO-Link master has been established, the master begins the automatic cyclic exchange of process data. The master receives new process output data (PDO) from the controller or field bus level and passes this on to the ejector for control. The feedback and measured values from the ejector are collected from the master as process input data (PDI) and forwarded to the system controller.

In the two possible IO-Link revisions 1.1 and 1.0, the process data from the ejector SCPSi is as follows:

PARAMETER DATA

In addition to the process data that is exchanged automatically, the IO-Link protocol provides an acyclical data channel for identification data, setting parameters or general feedback from the device. The available data objects are known as ISDU with IO-Link and are uniquely addressed within a device by their index and subindex.

Controller manufacturers usually provide a specialized function module – e.g. the “IOL_CALL” module for Siemens controllers – to enable these parameters to be accessed from a control program.

See the separate document, “SCPSi Data Dictionary”, to find out which parameter data is

offered by the ejector SCPSi and how this data is represented as ISDU objects. This document is available to download from www.schmalz.com.

CONFIGURATION SERVER

Since revision 1.1, the IO-Link protocol has contained an automated process for transferring data when a device is replaced. During this data storage mechanism, the IO-Link master mirrors all setting parameters for the device in a separate non-volatile memory. When a device is swapped for a new one of the same type, the setting parameters for the old device are automatically saved in the new device by the master.

In order for this to work with the ejector SCPSi, it must be operated on a master with IOLink revision 1.1 or higher and the data storage feature must be activated in the configuration of the IO-Link port.

A detailed description of the data storage mechanism cannot be provided here, however, note the following practical information:

 The device parameters are automatically mirrored in the master when the device is

configured using an IO-Link configuration tool such as S7-PCT.

 Changes to the parameters made in the user menu on the device are automatically

mirrored in the master.

 Changes to the parameters made by a control program using a function module are

not automatically mirrored in the master. In this case, mirroring can be triggered

manually by executing ISDU write access to the “System Command” parameter

with the “ParamDownloadStore” command (numerical value 5) once all the required

parameters have been changed.

 To ensure that data is transferred in the correct direction when a device is replaced, it

must be ensured that the new device is restored to the factory settings before it is connected to the IO-Link master. This can be done at any time using the function for restoring the factory settings, for example, via the operating menu.

START OF OPERATIONS

The communication LED on the IO-Link master port indicates the IO-Link communication has been successfully established.

Pressing the button displays the operating mode of the ejector.

A typical handling cycle is divided into three steps: pick-up, blow-off and the idle state. During the pick-up step, the switching threshold H2 is monitored to determine whether a sufficient vacuum has been established.

CONDITION MONITORING [CM]

Any condition monitoring events that occur during the suction cycle cause the system status light to immediately switch from green to yellow. The specific event that caused this switch can be seen in the “Condition Monitoring” IO-Link parameter. The following table shows its coding:

Coding of the condition monitoring warnings

Bit

Event

Valve protection function active

Set limit for evacuation time (t-1) exceeded

Set limit for leakage (-L-) exceeded

Threshold value H1 not reached

Dynamic pressure > (H2-h2) and < H1

Supply voltage outside the operating range

System pressure outside of working range

Page 56

SCHMALZ SCPSI - 2

5-56

The four bits with the lowest values describe events that can only occur once per suction cycle. They are reset at the start of every suction cycle and remain stable until after suctioning has finished.

Bit number 4, which describes excessive dynamic pressure, is initially deleted when the device is switched on and is only updated when a dynamic pressure value is detected again.

Bits 5 and 7 are permanently updated independently of the suction cycle and reflect the current values for the supply voltage and system pressure.

The measurement values for condition monitoring – the evacuation times t0 and t1 as well as the leakage area – are reset at the start of every suction cycle and updated at the point in time when they can be measured.

ENERGY MONITORING [EM]

The measurement value for the absolute air consumption (Air consumption per cycle) is reset at the start of every suction cycle and then permanently updated during the cycle. It can continue to change until after the end of blow-off.

To determine the other EM values – air consumption in percent and electrical energy consumption – the neutral phase of the suction cycle must also be taken into consideration. Therefore, the measurement values can only be updated once the next suction cycle starts and thus show the result of the previous cycle during the complete cycle.

PREDICTIVE MAINTENANCE [PM]

The measurement value for the leakage rate and the related quality assessment in percent are reset at the start of every suction cycle and permanently updated during the cycle as moving averages. The values therefore remain stable until after the suction cycle is complete.

The dynamic pressure (vacuum during unobstructed intake) and the related performance assessment in percent are initially unknown when the ejector is switched on. As soon as a dynamic pressure measurement can be performed, they are updated and retain their values until the next dynamic pressure measurement.

EPC-VALUES IN THE PROCESS DATA

To quickly and conveniently capture the most important results from the condition monitoring [CM], energy monitoring and predictive maintenance functions, these are also made available via the process input data of the device. The top 3 bytes of the process output data are also configured as a multifunctional data range, consisting of an 8 bit value (“EPC Value 1”) and a 16 bit value (“EPC Value 2”).

The current content of this data supplied by the ejector can be changed via the process output data using the 2 bits “EPC-Select”. The four possible ways in which this data is configured is listed in the following table:

PDO

PDI

EPC-Select

EPC-Value 1 (8-Bit)

EPC- Value 2 (16-Bit)

EPC-SelectAcknowledge

Current input pressure (Unit 0,1 bar)

Current Vacuum level (Unit 1 mbar)

Condition Monitoring

Evacuation time t

(Unit 1 ms) 1

Leakage rate (Unit 1 mbar/s)

Last measured dynamic pressure (Unit 1 mbar)

Supply voltage (Unit 0,1 V)

Air consumption (Unit 0,1 NL)

The switch is made depending on the structure of the automation system with some time delay. However, in order to be able to read the different pairs of values efficiently though a controller program, the bit EPC-Select-Acknowledge is provided in the process input data. The bit always accepts the values shown in the table. In order to read out all EPC values, the procedure illustrated in the following diagram is recommended:

Always start with EPC-Select = 00 and create the selection for the next value pair required, e.g. EPC-Select = 01. Now wait until the bit EPC-Select-Acknowledge changes from 0 to

1. This signifies that the values transmitted match the selection created and they can be accepted by the controller.

Now, switch back to EPC-Select = 00 and wait until the bit EPC-Select-Acknowledge is reset to 0 by the ejector. The process for the next value pair, e.g. EPC-Select = 10, can then be performed in the same way, and so on.

6 MAINTENANCE

GENERAL MAINTENANCE

EXTERIOR SOILING

Remove dirt on the exterior of the device with a soft cloth and soap suds (max. 60°C). Ensure that the silencer and the controller are not soaked with soap suds.

SILENCER

Because it is open, the silencer may be exposed to high levels of dust, oil, etc., which may dirty the silencer to the point of reducing the suction capacity. If this happens, it must be replaced. Cleaning is not recommended due to the capillary effect of the porous material.

PRESS-IN SCREENS

The vacuum and compressed air connections include press-in screens. Over time, dust, chips and other solids can become deposited in the screens. If you notice that the performance of the ejector system has declined, simply replace the

screens.

Do not operate the ejector system without the screens. This can damage the ejector system.
