2.1Emissions
The device emits noise due to operation with compressed air and a vacuum.
CAUTION
Noise pollution caused by exhaust air or leakage during operation
Hearing damage
4In the event of leakage, check connections and lines and remedy leakages
4Wear ear protectors.
2.2Intended Use
The terminal is built in accordance with the latest standards of technology and is delivered in a safe oper-
ating condition; however, hazards may arise during use.
The terminal is designed to generate a vacuum for gripping and transporting objects when used in con-
junction with suction cups. Depending on the design, the electrical control signals are transmitted directly
or via appropriate communication lines.
Neutral gases are approved as evacuation media. Neutral gases include air, nitrogen and inert gases (e.g.
argon, xenon and neon). For further information, see (> See ch. Technical Data).
The product is intended for industrial use.
Any other use is considered improper by the manufacturer and is deemed as contrary to the designated
use.

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 SCTMi, or SCTMi for short, is a compact unit of multiple vacuum gen-
erators 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 us-
ing just one vacuum system.
3.2Description of the Ejector
Every SCTMi mini compact ejector has an electrical connection to the voltage supply and to communica-
tion with the control for the superordinate machine.
The compressed air supply can be connected centrally for all ejectors. As an alternative, there can also be
a compressed air supply for each ejector.
3.2.1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.
During blow-off, [-FF] is shown on the display.
The ejector provides three blow-off modes for selection:
• Externally controlled blow-off
• Internally time-controlled blow-off
• Externally time-controlled blow-off

Product Description
10 / 24 EN-US · 30.30.01.02108 · 00 · 07/19
• Optional: External blow-off (EB function)
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:

6.1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.
6.2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.

EN-US · 30.30.01.02108 · 00 · 07/19 17 / 24
6.5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).

4Electrical connection may 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 ap-
plied.

7.1General Preparations
WARNING
Extraction of hazardous media, liquids or bulk material
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.
Always carry out the following tasks before activating the system:
1. Before each start of operations, ensure that the safety features are in perfect condition and fully
functional.
2. Check the device for visible damage and deal with any problems immediately (or notify the supervi-
sor).
3. Ensure that only authorized persons are present in the working area of the machine or system in or-
der to prevent any hazard from switching on the machine.
7.2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
necessary 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.
