1 Product Description
1.1 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 via the available menus or via IO-Link.
The following operating modes are available during the setup process:
• Setting mode (only via IO-Link) and
• Manual mode

4 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.
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
measured value is displayed as positive compared to the ambient air pressure.
4.1 Displaying the Basic Settings (Slide Show)
When you press the button from the home screen, the following parameters are automatically displayed one
after the other on the display (slide show):
• The vacuum unit
• The current operating mode (510 or 10L)
• The currently activated production setup profile (P-0 to P-3)
• The value of switching point SP1
• The value of reset point rP1
• The value of switching point SP2
• The value of reset point rP2
• The supply voltage US
The display cycle returns to the vacuum display after a complete cycle or can be canceled at any time by pressing
any button.

Parameter Explanation
5P1 Switching point 1 Value at which the control function deactivates
(only active if [ctr] = [on])
rP1 Reset point 1 Reset value 1 for the control function
5P2 Switching point 2 Switching value for the “Parts control” signal
rP2 Reset point 2 Reset value 2 for the “Parts control” signal
tbL Blow off time Setting of the blow-off time for time-controlled blow-off
CAL Zero-point adjustment

1nc Incorrect The entered value is not within the permissible value range.
This is an informational message that appears if incorrect information is
entered.
4.3 Changing the Parameters of the Main menu
If you wish to change values, e.g. the switching points, you have to enter the new value digit by digit.
1. Use the button to select the desired parameter.
2. Confirm using the button.
ðThe value that is currently set is displayed and the first digit flashes.
3. Use the button to change the value. The value increases by 1 each time that the button is pressed. After
9, the counter goes back to 0 when the button is pressed.
4. Press the button to save the modified value.
ðThe first digit is accepted and the second digit flashes.
5. Use the button to set the second digit.
6. Press the button to save the modified value.
ðThe second digit is accepted and the third digit flashes.
7. Use the button to set the third digit.
8. Press the button to save the modified value.
ðIf the entered value is within the permissible value range, it is accepted and the modified parameter is dis-
played.
ðIf the entered value is not within the permissible value range, this is briefly indicated on the display [1nc]
and the new value is not accepted.
If input is interrupted for longer than 1 minute or if no input is made, the measurement screen is automatically dis-
played.
5 Checking the Delivery
The scope of delivery can be found in the order confirmation. The weights and dimensions are listed in the delivery
notes.
1. Compare the entire delivery with the supplied delivery notes to make sure nothing is missing.
2. Damage caused by defective packaging or occurring in transit must be reported immediately to the carrier
and J.SchmalzGmbH.

6 Installation Instructions
CAUTION
Improper installation or maintenance
Personal injury or damage to property
4During installation and maintenance, make sure that the product is disconnected and depressur-
ized and that it cannot be switched on again without authorization.
For safe installation, the following instructions must be observed:
• Use only the connectors, mounting holes and attachment materials that have been provided.
• Mounting and removal must be performed only when the device is unpressurized and disconnected from the
mains.
• Pneumatic and electrical line connections must be securely connected and attached to the product.
7 Pneumatic Connection
CAUTION
Compressed air or vacuum in direct contact with the eye
Severe eye injury
4Wear eye protection
4Do not look into compressed air openings
4Do not look into the silencer air stream
4Do not look into vacuum openings, e.g. suction cups
CAUTION
Noise pollution due to incorrect installation of the pressure and vacuum connections
Hearing damage
4Correct installation.
4Wear ear protectors.
7.1 Connecting the Compressed Air and Vacuum
4Connect the compressed air hose to the connection

8 Electrical connection
CAUTION
Changing output signals when the product is switched on or plug is connected
Personal injury or damage to property!
4The electrical connection must be performed only by specialists who can evaluate the effects of
signal changes on the overall system.
NOTE
Incorrect power supply
Destruction of the integrated electronics
4Operate the product using a power supply unit with protected extra-low voltage (PELV).
4The system must incorporate safe electrical cut-off of the power supply in compliance with
EN60204.
4Do not connect or disconnect the connector under tension and/or when voltage is applied.
The electrical connection supplies the ejector with power and communicates with the controller of the higher-level
machine using defined outputs or via IO-Link.
Establish the ejector’s electrical connection using plug connector 1 as shown in the figure.
üProvide a connection cable with an M8 6-pole socket (customer’s responsibility).
4Attach the connection cable to the electrical con-
nection point (1) on the ejector, max. tightening
torque = hand-tight.
