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 SCTM.
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

3Product Description
3.1Mini Compact Terminal Description
The Schmalz mini compact terminal SCTMb, or SCTMb for short, is a compact unit of multiple vacuum
generators known as ejectors. Thanks to its modular design, up to 16 individual ejectors can be controlled
and configured independently. It can be used to handle different parts simultaneously and independently
using just one vacuum system.
To control the suction and blow-off functions, the SCTMb has a discrete interface for each valve. The com-
pressed air supply can be connected centrally for all ejectors. As an alternative, it can also be connected
separately for each ejector.
3.2Description of the Ejector
3.2.1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.
When objects with airtight surfaces are picked up, the integrated non-return valve prevents the vacuum
from dropping.

Product Description
10 / 30 EN-US · 30.30.01.02106 · 00 · 07/19
Optionally, “Ejector discs” with the function “External vacuum (EV)” can also be selected. With that func-
tion, the vacuum is supplied externally, and the air is sucked in through the vacuum connection.
3.2.2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, thereby depositing the workpiece quickly.
The blow off function can be triggered by the ejector in two ways:
• Externally controlled actuation of the blow off valve
• Optional: external blow off
3.3Variants and product keys
The item designation of the SCTM is composed of a product key, which indicates the number of ejectors
installed and their exact properties.
The SCTM product key (so-called system configuration), e.g. SCTMc-MP-6-XY-2AAF-2AB0-2AAH, is com-
posed as follows:

5Blow off modes
You can choose between two blow off modes.
5.1Externally Controlled Blow-Off
The “blow off” valve is controlled directly by the “blow off” command. The ejector switches to blow off
mode for as long as the “blow off” signal is present.
The “blow off” signal is given priority over the “suction” signal.
5.2Blow Off Using External Compressed Air
The ejector is also available with an additional compressed air connector to supply the blow off pulse sep-
arately (external blow off function = “EB”).
While the vacuum is interrupted, small workpieces are carefully deposited using a blow off pulse.
Through fine adjustment of the vacuum, the blow off of small workpieces is prevented.
The air supply opening for blow off is controlled separately. Therefore, it is easy to fine-tune the blow off
air using either the conventional flow rate setting or an external regulator.
The release pressure can be adapted to the workpiece.

7.1Installation Instructions
CAUTION
Improper installation or maintenance
Personal injury or damage to property
4Prior to installation and before maintenance work, the compact terminal must be dis-
connected from the power supply and secured against unauthorized restart!
For safe installation, the following instructions must be observed:
1. Use only the connections, mounting holes and attachment materials that have been provided.
2. Firmly connect and secure pneumatic and electrical line connections to the compact terminal.
3. Ensure that there is adequate installation space in the area where the product will be installed.
7.2Installation
The mini compact terminal may be installed in any position.
The mini compact terminal is attached using the mounting slots (4 pieces). There is also the option of
mounting DIN rails.
4The four slots are used to attach them. The
mini compact terminal must be secured in
place using at least 4 M4 screws. The maxi-
mum tightening torque is 2Nm.
4As an option, the holes can be used to attach
DIN rails for mounting.

7.5Optional: External blow-off connection (EB)
The terminal is also available with an additional compressed air connector for the blow-off function.
With the external blow-off function (EB), the blow-off pulse is controlled separately and independently of
the compressed air supply for vacuum generation, allowing you to use a different medium (e.g. nitrogen)
for the blow-off function.
It also allows you to precisely set the blow-off pressure using an external pressure regulator (between 2
and 6 bar).
The blow-off flow rate can also be set between 0% and 100% directly on the respective ejector disc. This
can be used, for example, to set down small and lightweight workpieces with high positioning precision.
The hose size and the thread on the connector depend on the particular ejector disc and can have the fol-
lowing dimensions:
• Push-in: 8/6
• Thread: 1/8" thread, female
4Connect the compressed air hose for external
blow-off (connector marked with 1A) and ad-
just the blow-off flow rate using the adjusting
screw (2).

7.6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.
