2Fundamental Safety Instructions
2.1Safety
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.
WARNING
Uncontrolled movements of system components or falling of objects caused by in-
correct activation and switching of the Ejector while persons are in the plant
(safety door opened and actuator circuit switched off)
Serious injury
4Ensure that the valves and ejectors are enabled via the actuator voltage by installing a
potential separation between the sensor and actuator voltage.
4Wear the required personal protective equipment (PPE) when working in the danger
zone.
CAUTION
Depending on the purity of the ambient air, the exhaust air can contain particles,
which escape from the exhaust air outlet at high speed.
Eye injuries
4Do not look into the exhaust air flow
4Wear eye protection
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 with discrete signals or via IO-Link.
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.

Product Description
12 / 72 EN-US · 30.30.01.01484 · 00 · 01/21
Meaning of the Vacuum Limit Value LEDs
The LEDs for the vacuum limit values H1 and H2 indicate the current level of the system vacuum relative
to the configured limit values. Their display is independent of the switching function and assignment of
the output, and independent of whether the condition monitoring function is active.
Display Ejector state
LEDs both off Rising vacuum:
Vacuum < H2
Falling vacuum:
Vacuum < (H2-h2)
H2 LED lit steadily Rising vacuum:
Vacuum > H2 and < H1
Falling vacuum:
Vacuum > (H2-h2) and < (H1-h1)
Both LEDs lit steadily Rising vacuum:
Vacuum > H1
Falling vacuum:

Operating and Menu Concept
EN-US · 30.30.01.01484 · 00 · 01/21 17 / 72
5Operating and Menu Concept
The parameters can also be set using three buttons. The current system status and the settings are shown
on a display.
The unit is operated via three buttons on the foil keypad. Settings are configured using software menus.
The operating structure is divided into settings in the main menu and configuration menu. Setting the
ejector in the main menu is sufficient for standard applications. The advanced configuration menu is
available for applications with special requirements.
If settings are changed, undefined states of the system may occur for a short time (for approx. 50ms).
5.1Enabling the Menu
Menus can be protected against unauthorized access by defining a PIN [Pin] in the configuration menu.
When the lock is active, [Loc] flashes on the display or the PIN is requested.
The menus are accessed as follows:
1. Press the button
ðThe display changes to input
2. Use the or buttons to enter the first digit of the PIN
3. Confirm using the button
4. Enter the remaining digits in the same way.
5. To enable the device using the menu, press the button
The lock is activated again automatically after you leave the selected menu or close the function.
The PIN [000] must be set for permanent deactivation of the lock.
Tips and Tricks for Parameter Setting
• By pressing the or button for approx. 3 seconds, the value to be changed is
scrolled through quickly
• If you exit the changed value by briefly pressing , the value will not be applied.
5.2Main Menu
All the settings for standard ejector applications can be configured and read through the main menu:
1. Open the main menu by pressing the button.
2. Use or to select the desired adjustable parameter.
3. Confirm the selection with the key.
4. Use the or keys to set the value of the parameter.
5. To save and exit the menu, press and hold the key for at least 2 seconds.
ðThe displayed value flashes to confirm.

Operating and Menu Concept
18 / 72 EN-US · 30.30.01.01484 · 00 · 01/21
The following table shows an overview of the display codes in the main menu:
Display code Parameter Explanation
x-1 Vacuum limit value H1 Value at which the control function deactivates
(only if ctr = on and oN5 are active)
h-1 Hysteresis value h-1 Hysteresis value for the control function
x-2 Vacuum limit value H2 “Part Present” check switching value
h-2 Hysteresis value h-2 “Part Present” check hysteresis value
tbL Blow off time Only activated for E-t or l-t
CAL Calibration Calibrate the vacuum sensor
The factory settings for the parameters are listed in the Technical Data section.
5.3Configuration Menu
An extended configuration menu is available for applications with special requirements.
1. Open the configuration menu by pressing the button for more than 3 seconds.

5.5Individual Functions
Displaying the vacuum level:
Outside of the menu, the ejector is in display mode and the current vacuum level is displayed.
In display mode, a specific function is assigned to each key.
Displaying the supply voltage:
4Press the button
ðThe supply voltage that is currently applied to the ejector is displayed in volts.
After 3 seconds, the screen returns to the vacuum display.
The displayed voltage is a guideline value and is used for comparative measurements.
Displaying the operating mode:
4Press the button
ðThe current operating mode is displayed.
It is either standard I/O (SIO) mode [510] or IO-Link mode [10L].
In IO-Link mode, you can also press the button again to view the IO-Link Standard (1.0, 1.1) that is cur-
rently in use.
