2Fundamental Safety Instructions
2.1Safety
The ejector emits noise due to its use of compressed air.
WARNING
Noise pollution due to the escape of compressed air
Hearing damage!
4Wear ear protectors.
4The ejector must only be operated with a silencer.
WARNING
Uncontrolled movements of system components or falling of objects caused by in-
correct activation and switching of the Ejector while persons are in the plant
(safety door opened and actuator circuit switched off)
Serious injury
4Ensure that the valves and ejectors are enabled via the actuator voltage by installing a
potential separation between the sensor and actuator voltage.
4Wear the required personal protective equipment (PPE) when working in the danger
zone.
CAUTION
Depending on the purity of the ambient air, the exhaust air can contain particles,
which escape from the exhaust air outlet at high speed.
Eye injuries
4Do not look into the exhaust air flow
4Wear eye protection
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.

3.1Mini 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.
3.2Product Key for the Mini Compact Terminal
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-6-XY-2AAF-2AB0-2AAH, is composed
as follows:
Property Variants Comment
Product class SCTMc terminal incl. c-ejectors

Ejector block 1 2 AAF individual discs Contains the complete “type informa-
tion” of the blocked individual discs
Ejector block 2 2 AB0 individual discs

Important Notes:
• Only unmixed terminals may be constructed (b, c, or i ejectors)
• A maximum of 4 individual discs can be used
• Identical individual discs must be installed grouped together as blocks.

3.4Description 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 is connected centrally for all ejectors.
3.4.1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, 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.

Product Description
EN-US · 30.30.01.02041 · 01 · 02/21 11 / 36
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.
An integrated sensor records the vacuum generated by the venturi nozzle. The exact vacuum value is
shown on the display.
When objects with airtight surfaces are picked up, the integrated non-return valve prevents the vacuum
from dropping.
3.4.2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.
During blow-off, [-FF] is shown on the display.
3.5Ejector Designation
The breakdown of the item designation (e.g. SCPMtc 10 6/4 NC JST-5 ABF) is as follows:
Property Variants

The LEDs for the switching points SP1 and SP2 (limit values) indicate the current level of the system vac-
uum relative to the configured limit values. Their behavior is independent of the control function and the
assignment of the output.
The table below explains the meaning of the LEDs:

6.3Changing the Blow-Off Flow Rate on the Ejector
Do not overwind past the stop on the valve screw. The blow off flow rate can be adjusted
within the range between 0% 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.
