Pneumatics
Control technology
The Schmalz Compact terminal SCTSi, SCTSi for short, is a compact unit consisting of individual discs that
links several vacuum generators, ejectors, IO-Link class B masters and digital input modules (DI modules).
Thanks to its modular design, up to 16 individual ejectors can be controlled and configured indepen-
dently. It can be used to handle different parts simultaneously and independently using just one vacuum
system.
Up to 8 corresponding IO-Link class B or class A devices can be connected via the IO-Link masters (2 maxi-
mum).
Digital input signals (up to 48) from peripheral devices are recorded via the DI modules (maximum 6).
The Compact terminal SCTSi has an industrial Ethernet interface. The compressed air supply can be con-
nected centrally for all ejectors. As an alternative, it can also be connected separately for each ejector.
Each ejector has an autonomous energy and process control for monitoring the vacuum circuit.
All settings, parameters and measurement and analysis data are made available centrally via the interface.
Additionally, much of the information and status reports for the Compact terminal SCTSi can be accessed
using wireless communication with NFC (Near Field Communication).
3.1.1Variants and Product Keys
The item designation of the Compact terminal SCTSi is composed of a product key, which indicates the
number of ejectors installed and their precise properties. Additional modules such as the IO-Link master
and DI module can also be provided.
The SCTSi product key (system configuration), e.g. SCTSi-EIP-16-AA-10A46-2A4H-1BEC-3BP4-24, is com-
posed as follows:

3.3Description of the Ejector
The compact ejectors of the SCTSi are supplied with electrical power by internal transmission. The same
bus interface is used for communication with the controller of the higher-level machine. The electrical
connection is made centrally via the bus module.
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
suction exit together via the silencer.
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.
An integrated sensor records the vacuum generated by the venturi nozzle. The vacuum value is displayed
via the LED bar and can be read out via the process data.
The diagram below shows the vacuum curve for when the air saving function is activated:
H1
H1-h1
H2
H2-h2
Vacuum
[mbar]
Vacuum on Time [s]

Part inspection:
1 => activated
2 => deactivated
The ejector also has a button that can be used for manual operation.
The ejector has an integrated air saving function and automatically regulates the vacuum in suction
mode:
• The electronics switch the venturi nozzle off (“Venturi nozzle inactive”) as soon as the set vacuum
limit value (switching point H1) is reached.
• When objects with airtight surfaces are picked up, the integrated non-return valve prevents the vac-
uum from dropping.
• If the system vacuum drops below the limit value switching point H1-h1 due to leaks, the venturi
nozzle is switched back on.
• Depending on the vacuum, the H2 process data bit is set once a workpiece is picked up safely. This
enables the further handling process.

3.3.1Ejector Variants
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) version, the venturi nozzle is activated.
• In the IMP variant, the venturi nozzle is actuated using the same principle as the NC variant. This
means that pulse control via the suction command is not necessary. Transmission in pulses is carried
out internally in the ejector depending on the requested Suction command.
Power Failure or Communication Interruption with the Ejector Variant IMP
In the ejector variant IMP, the ejector remains in “Suction” mode if the power supply fails during auto-
matic mode. This prevents the object being gripped from falling from the suction cup in the event of a
power failure (or failure of the controller or its communication). This also applies when the ejector was in
the “Venturi nozzle inactive” state with the air-saving function activated. In this case, the ejector switches
to “Venturi nozzle active,” i.e., to continuous suction. When the power supply actuator returns, the ejec-
tor remains in automatic mode with the air-saving function activated.
If the pulse ejector is in the “Suction” operating state when the terminal is restarted or communication is
re-established (after a communication interruption with the controller), it can only be reset to the “No
suction” operating state either by a falling edge of the suction command (option 1) or by a rising edge of
the blow-off command (option 2).

Undervoltage for Ejector Variant IMP
In contrast to a power failure or communication interruption, the suction command is reset in the event
of undervoltage (without restarting the terminal) as soon as the supply voltage is in the permissible range
again and Bit = false is present on the suction ejector.

Undervoltage (sensor or actuator voltage)
The blow off valve on the ejector is activated and deactivated using the blow off command. The valve is
always designed as an NC (normally closed) variant and switches the air pressure channel to the vacuum
connection for the duration of activation. If both suction and blow-off are activated, blow-off is given
higher priority and the venturi nozzle is not activated.
If the ejector is in blow-off mode when the power supply fails, the blow-off is stopped and the ejector is
set to “pneumatically OFF”. This prevents unnecessary consumption of compressed air, thus saving energy
and additional costs. When the power supply returns, the ejector remains in “pneumatically OFF” mode.
If communication of the higher-level bus system (Profinet, Ethernet/IP, EtherCAT) is inter-
rupted, the ejectors retain their last activated state of suction, the neutral position or blow-off.

NOTE
The actuator power supply of each IO-Link master port is protected against short
circuit, but not against overload.
Damage to the device
4Ensure that the maximum permissible current values are observed.
NOTE
The actuator power supply of each IO-Link master port is switched on after a
power-up. This must be observed when connecting class A devices.
Damage to a connected device
4Ensure that the actuator voltage is deactivated if the voltage at this pin can cause dam-
age to the connected device (actuator voltage UA can be deactivated via the corre-
sponding parameters).

NOTE
Power load greater than 16A
Damage to the device
4Ensure that the maximum permissible total current (for the whole terminal) of 16A is
not exceeded.
4In addition, suitable fuse protection of the supply line is necessary.
4The supply line must be designed in accordance with the planned power consumption
and the length of the line. A cable cross-section of 2.5 mm² is recommended.
If communication of the higher-level bus system (Profinet, Ethernet/IP, EtherCAT) is inter-
rupted, the output process data of the IO-Link masters (IO-Link output) are reset to 0 (zero) for
safety reasons.
3.4.1Description
The IOL master is a decentralized IO-Link, input and output module. It enables the connection of up to
four IO-Link devices. These can be actuators, sensors, or a combination of both.
Two LEDs are assigned to each IO-Link master port. The LEDs indicate the communication status and the
actuator supply voltage.
Up to four IO-Link devices (with the possible transmission speeds COM1, COM2, COM3) can be connected
to each IO-Link master. All communication takes place via the industrial Ethernet interface. All master
ports are designed as Class B ports and marked accordingly. This allows sensor-actuator systems to be op-
erated while taking electrical isolation into account. IO-Link class A devices can also be connected using a
3-pole sensor connection line. Up to 2A per port from the actuator supply voltage are available for the
actuators. If the actuator current is exceeded, the corresponding port is switched off.
The maximum permissible total current of 16A (of the whole terminal) must not be exceeded. The power
consumption of other components within the whole terminal must also be taken into account --> see 4.2
“Electrical and Technical Parameters”.
The pin assignment corresponds to the IO-Link specification for class B ports. See also chapter 8.4.3.
The IO-Link ports of the device satisfy the requirements of the IO-Link specification 1.1.
Max. line length per IO-Link port: 20 m.
