5General Description of Functions
5.1Applying Suction to the Workpiece/Part
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, 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 suction exit
together via the silencer or exhaust air channel.
The “Suction” pilot valve is controlled directly.
• In the NO (normally open) variant, the venturi nozzle is deactivated when
the suction signal is received.
• In the NC (normally closed) variant, the venturi nozzle is activated when the
suction signal is received.
When objects with airtight surfaces are picked up, the integrated non-return valve prevents the vacuum
from dropping.
5.2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, allowing the workpiece/part to be deposited quickly.
The “Blow off” pilot valve is controlled directly. The ejector switches to blow off mode for as long as the
signal is present.
5.3Restricted Mode
The “Blow-off” and “Suction” pilot valves have a button for manual operation.
This can be used to actuate the valve manually without a power supply.
üThe compressed air supply is connected.
4To activate the valve in question, trigger the
manual auxiliary actuation using an imple-
ment such as a ballpoint pen.

7.1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
depressurized 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 unpres-
surized and disconnected from the mains.
• Pneumatic and electrical line connections must be securely connected and
attached to the product.
7.2Mounting
The ejector may be installed in any position.
There are two 4.4 mm mounting holes for mounting the ejector.
A DIN rail mount for DIN rail TS35 can be used as a mounting option.

When mounting with fastening screws, use M4 washers (2Nm max. tightening torque).
For the start of operations, the ejector must be connected to the control via the connection plug with a
connection cable. The compressed air required to generate the vacuum is connected via the compressed
air connection. The compressed air supply must be supplied by the higher-level machine.
The vacuum circuit is connected to the vacuum connection.
The installation process is described and explained in detail below.

üThe corresponding pneumatic hose is handy.
4The compressed air connection is marked with
the number 1 on the ejector (Shown here in
the image as an example.).
The vacuum connection is marked with the
number 2 on the ejector.
Press the corresponding pneumatic hoses
(compressed air supply and suction cup con-
nection) as far as possible into the plug-in
screw unions.
ðThe pneumatic hoses fit tightly in the
plug-in screw unions.
7.3.2Instructions for the Pneumatic Connection
Use only screw unions with cylindrical G-threads for the compressed air and vacuum connection!
To ensure problem-free operation and a long service life for the product, only use adequately maintained
compressed air and take the following requirements into account:
• Use of air or neutral gas in accordance with EN 983, filtered 5 μm, oiled or
unoiled.
• Dirt particles or foreign bodies in the product connections, hoses or pipe-
lines can lead to partial or complete malfunction.
1. Shorten the hoses and pipelines as much as possible.
2. Keep hose lines free of bends and crimps.
3. Only use a hose or pipe with the recommended internal diameter to connect the product; otherwise,
use the next largest diameter.
- On the compressed air side, ensure that the internal diameter has the dimensions required for the
product to achieve its performance data.
- On the vacuum side, ensure that the internal diameters have the necessary dimensions for prevent-
ing high flow resistance. If the selected internal diameter is too small, the flow restrictor and the
evacuation times increase and the blow off times are extended.

7.4Electrical Connection
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 ap-
plied.
The electrical connection is established directly via the connection plugs of the valves. The connection of
the valves is independent of the polarity.
üProvide connection cable (for example, 2x item no.: 21.04.06.00086)
4Insert the connection cables into the electrical
connections (1 and 2) until they click into
