2Fundamental Safety Instructions
2.1Emissions
The ejector emits noise due to its use of compressed air.
WARNING
Noise pollution due to the escape of compressed air
Hearing damage!
4Wear ear protectors.
4The ejector must only be operated with a silencer.
2.2Intended Use
The ejector is built in accordance with the latest standards of technology and is safe to operate upon de-
livery; however, hazards can still arise during use.
The ejector is designed to generate a vacuum for gripping and transporting objects when used in conjunc-
tion with suction cups. It is operated by a controller via discrete signals.
Neutral gases are approved as evacuation media. Neutral gases include air, nitrogen and inert gases (e.g.
argon, xenon and neon).
The product is intended for industrial use.
Intended use includes observing the technical data and the installation and operating instructions in this
manual.
2.3Non-Intended Use
WARNING
Extraction of hazardous media, liquids or bulk material
Personal injury or damage to property!
4Do not extract harmful media such as dust, oil mists, vapors, aerosols etc.
4Do not extract aggressive gases or media such as acids, acid fumes, bases, biocides, dis-
infectants or detergents.
4Do not extract liquids or bulk materials, e.g. granulates.
Schmalz accepts no liability for damages caused by non-intended usage of the ejector. In particular, the
following are considered non-intended use:
• Use in potentially explosive atmospheres
• Use in medical applications
• Lifting people or animals
• Evacuation of objects that are in danger of imploding

2. The product must be operated only by persons who have undergone appropriate training.
This operating instructions is intended for fitters who are trained in handling the product and who can
operate and install it.
2.5Modifications to the Ejector
Schmalz assumes no liability for consequences of modifications over which it has no control:
1. The ejector must be operated only in its original condition as delivered.
2. Use only original spare parts from Schmalz.
3. The ejector must be operated only in perfect condition.

3.1Description of the Ejector
3.1.1Suction of the Workpiece (Vacuum Generation)
The ejector is designed for vacuum handling of airtight parts in combination with suction systems. The
vacuum is generated in a nozzle according to the Venturi principle, i.e. by using suction generated by the
flow of accelerated compressed air. Compressed air is channeled into the ejector and flows through the
nozzle. A vacuum is generated immediately downstream of the motive nozzle; this causes the air to be
sucked through the vacuum connection. The air and compressed air that have been removed by the suc-
tion exit together via the silencer.
The venturi nozzle on the ejector is activated and deactivated using the suction command:
• In the NO (normally open) variant, the venturi nozzle is deactivated when the suction signal is re-
ceived.
• In the NC (normally closed) variant, the venturi nozzle is activated when the suction signal is re-
ceived.
An integrated sensor records the vacuum generated by the venturi nozzle. The exact vacuum value is
shown on the display.
The diagram below shows the vacuum curve for when the air saving function is activated:
Vacuum
[mbar]
Vacuum on Time [s]
SP1
SP2
rP1
rP2
OUT=on
OUT=off
The ejector has an integrated air saving function and automatically regulates the vacuum in suction
mode:
• The electronics switch the venturi nozzle off as soon as the vacuum limit value set for switching
point SP1 is reached.
• When objects with airtight surfaces are picked up, the integrated non-return valve prevents the vac-
uum from dropping.
• If leaks cause the system vacuum to drop below the limit value configured for the rP1 switching
point, the venturi nozzle is switched back on.
• The OUT output is set once a workpiece is picked up securely, based on the vacuum value. This en-
ables the further handling process.

3.1.2Depositing the Workpiece/Part (Blowing Off)
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.
During blow off, [-FF] is shown on the display.
The ejector provides two blow off modes for selection:
• Externally controlled blow off
• Internally time-controlled blow off
• Optional: external blow off
3.2Operating Modes
If the ejector is connected to the supply voltage, it is ready for operation. This is the normal operating
mode, in which the ejector is operated by the system controller.
The ejector is parameterized using the provided menus.
“Manual operation” mode can be selected during the setup process.

5Operating and Menu Concepts
The ejector is operated using two buttons on the foil keypad:
MENU BUTTON PLUS BUTTON
Navigation is divided into three menus:
• The main menu: for standard applications
• The Extended Functions (EF) menu: for applications with special requirements
• The Info menu (INF): for reading out system data such as counters, the software version, etc.
If settings are changed, undefined states of the system may occur for a short time (for approx. 50ms).
The following information can be shown on the display:
• The current vacuum measurement value
• The selected menu item
• The settings
• Error messages in the form of error codes
The operating menu’s home screen shows the currently measured vacuum level in the selected display
unit. The available units are millibar, kilopascal, inHg and psi. The measured value is displayed as positive
compared to the ambient air pressure.
The menus will automatically close if no buttons are pressed for 1 minute.
The display also returns to the home screen when an error occurs so that the error code can be displayed.
A menu can be called up and used again afterward.
5.1Button Assignments in Display Mode
In display mode, a specific function is assigned to each key.
5.1.1Opening the Menu
Press the PLUS BUTTON to open the menus as follows:
4Press the button briefly.
ðThe main menu opens with the firstparameter[5P1].
Opening the EF menu for extended functions:
1. Press the button several times until the parameter EF appears on the display.
2. Press the button to switch to the EF submenu for extended functions.
ðThe EF menu opens with the first parameter [ctr].
