5 General Description of Functions
5.1 Picking up 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, using suction generated by the flow of accelerated com-
pressed air. Compressed air is channeled into the ejector and flows through the nozzle. A vacuum is generated im-
mediately 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 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 man-
ual auxiliary actuation using an implement such as
a ballpoint pen.

“Suction” pilot

5.4 Changing the Blow-Off Flow Rate on the Ejector
Do not overwind the stop on the valve screw. A minimum flow rate of approx. 15% is always neces-
sary for technical reasons. The blow-off volume flow can be set between 15% and 100%.
There is a valve screw below the vacuum connection that can be used to adjust the blow-off flow rate. The valve
screw is equipped with a stop on both sides.

1. Turn the valve screw clockwise to reduce the flow rate.
2. Turn the valve screw counterclockwise to increase the flow rate.
6 Transport and Storage
6.1 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.
7 Installation
7.1 Installation Instructions
CAUTION
Improper installation or maintenance
Personal injury or damage to property
4During installation and maintenance, make sure that the ejector is disconnected and depressur-
ized and that it cannot be switched on again without authorization.
For safe installation, the following instructions must be observed:
1. Use only the connections, mounting holes and attachment materials that have been provided.
2. Carry out mounting and removal only when the device is in an idle, depressurized state.
3. Pneumatic and electrical line connections must be securely connected and attached to the ejector.
EN-US · 30.30.01.02662 · 00 · 02/21 11 / 20

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.

10.1 Safety
Maintenance work may only be carried out by qualified personnel.
WARNING
Risk of injury due to incorrect maintenance or troubleshooting
4Check the proper functioning of the product, especially the safety features, after every mainte-
nance or troubleshooting operation.
NOTE
Incorrect maintenance work
Damage to the ejector!
4Always switch off supply voltage before carrying out any maintenance work.
4Secure before switching back on.
4The ejector must only be operated with a silencer.
4Before carrying out any work on the system, ensure that the ejector’s compressed air circuit is vented to at-
mospheric pressure!
10.2 Cleaning the Ejector
1. For cleaning, do not use aggressive cleaning agents such as industrial alcohol, white spirit or thinners. Only
use cleaning agents with pH 7–12.
2. Remove dirt on the exterior of the device with a soft cloth and soap suds at a maximum temperature of 60°C.
Make sure that the silencer is not soaked in soapy water.
3. Ensure that no moisture can reach the electrical connection or other electrical components.
10.3 Replacing the Silencer Insert
Heavy infiltration of dust, oil, and so on, may contaminate the silencer insert and reduce suction capacity. Cleaning
the silencer insert is not recommended due to the capillary effect of the porous material.
If the suction capacity decreases, replace the silencer insert:
16 / 20 EN-US · 30.30.01.02662 · 00 · 02/21

üDeactivate the ejector and disconnect it from the supply lines.
1. Unlock the silencer cover by turning the bayonet
fastener 90°.
2. Remove the silencer cover.

3. Replace the silencer insert (1).
10.4 Cleaning or Changing the Nozzle
The easy access to the silencer insert and nozzle provided by the silencer cover with bayonet fastener ensures that
the nozzle is easy to clean and replace.
üThe ejector is deactivated and disconnected from the supply lines.
üThe silencer cover and silencer insert are removed ((> See ch. Replacing the Silencer Insert,Page 16)).
1. Pull the nozzle out of the holder.
