Specialist personnel must be familiar with current safety rules and requirements. For ex-
ample, 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 feedback
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 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.
INSTALLATION AND OPERATION
For safe installation and trouble-free operation, please observe and comply with the following points:
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.
SCHMALZ SCPS

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.
The ejector also has a manual mode. In this mode, the ejector can be controlled
using the buttons on the ejector’s foil keypad. See the “Manual mode” section for
more details.
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 serves as the basis for displaying the system states and
switching the output.
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.
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.
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.

VACUUM/PRESSURE DISPLAY
The current system vacuum is always displayed in the 8-digit LED bar display. The 2 LEDs,
H1 and H2, indicate which range the vacuum level is in relative to the threshold
values set.
VERSIONS
Each ejector has a specific item designation (e.g. SCPS-10-G2-NO-M12-5-PNP).
The item designation can be broken down as follows:
EJECTOR VERSION PNP OR NPN
The switching properties of the ejector’s electrical inputs and output are permanently set on
the device, meaning they are independent of the version.
ELECTRICAL CONNECTION
The electrical connection is established using a 5-pin M12 connector that supplies the ejector with voltage, and contains the two input signals and the output signal. The inputs and
outputs are not electrically isolated from one another.

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.
In addition to automatic mode, you can also change the operating mode of the ejector to
manual mode using the buttons on the foil keypad.
Parameterization of the ejector is always performed in automatic 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.
Starting manual mode always switches the ejector to “pneumatically OFF” mode.
In other words, starting manual mode interrupts an active suction process.
Danger due to falling parts.
If the air-saving function is activated this is also activated in manual mode.
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).
GENERAL FUNCTIONS
MANUAL MODE
In manual mode, the pick-up 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.
ACTIVATING MANUAL MODE
Activate manual mode as follows:
Press and hold the and buttons together for more than 3 seconds
MANUAL SUCTION
In manual mode, suction is activated by pressing the button. Exit suction mode by
pressing the
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

The time-controlled blow-off is activated by setting a value greater than zero for
the blow-off time.
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
CONTROL FUNCTION
This ejector function allows you to conserve compressed air. 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 control function can be deactivated by setting the threshold value for H1 to “Max.”.
BLOW-OFF MODES
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.
INTERNALLY TIME-CONTROLLED BLOW-OFF
The “Blow-off” valve is automatically activated for the time period set as soon as the ejector
leaves the “Suction” mode. This function makes it possible to save an output on the control-
ler.
SIGNAL OUTPUT
The ejector has a signal output.
OUTPUT FUNCTION
The signal output is a normally open (NO) contact and cannot be changed.
The signal output is switched on or off when the system vacuum is higher or lower than the
relevant threshold value.
SCHMALZ SCPS

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%.
+
-
VACUUM UNIT
The vacuum level in the LED bar is shown as a percentage of the maximum possible vacuum.
If the vacuum is outside the permitted range, the LED next to this bar will flash rapidly. That
means the LED flashes “10%” when overpressure is applied.
OPERATING VOLTAGE DISPLAY
In operating modes in which no LEDs are activated, the “Max” LED will light up briefly. This
indicates an operating voltage.
LOCKING THE KEYPAD
Pressing the and keys at the same time locks the keypad. Pressing both keys again
unlocks the keypad.
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.

The value set for H1 must always be greater than the value set for H2. Only settings that meet this specification can be made.
4 OPERATION AND SETTINGS
The three keys on the foil keypad are used for operation and setting the parameters. If no
parameters are set, the ejector is in display mode. The current vacuum is displayed.
VIEWING AND SETTING PARAMETERS
The following parameters can be set for the ejector:
H1 threshold value for the controller
H2 threshold value for the signal output
Blow-off period for time-controlled blow-off
The hystereses for the threshold values are pre-defined.
*If a value > (H1-h1) is selected for H2, the hysteresis h1 will be dynamically adjusted so
that (H1-h1) is 25 mbar above H2.
For H1, the hysteresis is always 20% of the H1 value; the hysteresis h2 is always 10 mbar.
By pressing the key, you can view the first parameter (threshold value H1). If you press
the key again, the second parameter (threshold value H2) and the third parameter (blow

OVERVIEW
During operation of the ejector, all input and output signals are connected to a controller,
either directly or using intelligent terminal boxes.
For this purpose, not only the supply voltage but also two input signals and one output signal should be connected to allow the ejector to communicate with the controller.
With these connections, the basic functions of the ejector can be used, including suction,
blow-off and feedback signals. The individual connections are as follows:

PNEUMATIC CONNECTION
Use only well-maintained compressed air (air or neutral gas according to EN 983, filtered
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. Blowoff 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.
RECOMMENDED LINE CROSS-SECTIONS (INTERNAL DIAMETERS)

Do not operator the ejector system without press-in screens! This can damage
the ejector system.
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 FILTERS
The vacuum and compressed air connections contain press-in screens.
Over time, dust, chips and other solids can become deposited in the filters.
If you notice that the performance of the ejector system has declined, simply replace the
screens.

7 TECHNICAL DATA
ELECTRICAL PARAMETERS
1)
The power supply must comply with the requirements of EN60204 (protective extra-low voltage).
The power supply, signal inputs and signal outputs are all protected against reverse polarity.
2)
Plus the output currents
3)
The signal output is protected against short circuits. However, the signal output is not secured against overloading.
Constant load currents of > 0.15 A can lead to unacceptable heat levels and subsequent destruction of the ejector.
