2Fundamental Safety Instructions
2.1Emissions
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.
2.2Intended 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 control signals are transmitted directly or via ap-
propriate 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.
2.3Non-Intended Use
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.
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

3Product Description
3.1Mini compact terminal description
The Schmalz mini compact terminal SCTMc, or SCTMc 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.
3.2Description of the Ejector
Every SCTMc 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.
3.2.1Suction 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 or exhaust air channel.
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.
Product Description
10 / 26 EN-US · 30.30.01.02107 · 00 · 07/19
• In the NC (normally closed) variant, the venturi nozzle is activated when the suction signal is re-
ceived.
An integrated sensor records the vacuum generated by the venturi nozzle. The exact vacuum value is
shown on the display.
The diagram below shows the vacuum curve for when the air saving function is activated:
Vacuum
[mbar]
Vacuum on Time [s]
SP1
SP2
rP1
rP2
The ejector has an integrated air saving function and automatically regulates the vacuum in suction
mode:
• The electronics switch the venturi nozzle off as soon as the vacuum limit value set for switching
point SP1 is reached.
• When objects with airtight surfaces are picked up, the integrated non-return valve prevents the vac-
uum from dropping.
• If leaks cause the system vacuum to drop below the limit value configured for the switching point
rP1, the venturi nozzle is switched back on.
3.2.2Depositing 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 quickly deposited.
During blow off, [-FF] is shown on the display.
The ejector provides two blow off modes for selection:
• Externally controlled blow off
• Internally time-controlled blow off
3.3Variants 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:
