2 Fundamental Safety Instructions
2.1 Safety
The mini compact valve emits noise due to the operation of the vacuum and compressed air.
WARNING
Noise pollution due to the escape of compressed air
Hearing damage!
4Wear ear protectors.
WARNING
Uncontrolled movements of system components or falling of objects caused by incorrect ac-
tivation 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 es-
cape 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 valve is designed to monitor and control the externally supplied compressed air and vacuum media for grip-
ping and transporting objects when used in conjunction with suction cups. Depending on the design, the 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).
The product is built in accordance with the latest standards of technology and is delivered in a safe operating con-
dition; however, hazards may arise during use.
The product is intended for industrial use.
Intended use includes observing the technical data and the installation and operating instructions in this manual.
2.3 Non-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, disinfectants
or detergents.
4Do not extract liquids or bulk materials, e.g. granulates.
4 / 16 EN-US · 30.30.01.02105 · 02 · 12/21

NOTE

3 Product Description
3.1 Description of the Mini Compact Valve
3.1.1 Picking Up the Workpiece
The valve is designed for vacuum handling of airtight parts in combination with suction systems. The vacuum is
supplied externally and the air is sucked in through the vacuum connection.
The vacuum valve is opened or closed using the suction command:
• In the NO (normally open) variant, the valve is closed when the suction signal is received.
• In the NC (normally closed) variant, the valve is opened when the suction signal is received.
A sensor integrated in types "i" and "c" detects the vacuum present. The exact vacuum level is shown on the dis-
play and, with the "i" version, can also be read from the IO-Link process data.
The diagram below shows the vacuum curve when the control function is activated:

Vacuum
[mbar]
Vacuum on Time [s]
SP1
SP2
rP1
rP2
OUT=on
OUT=off
The valve has an integrated control function and automatically regulates the vacuum in suction mode:
• The electronics switch the vacuum transmission 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 vacuum from
dropping quickly.
• If leaks cause the system vacuum to drop below the limit value configured for the switching point rP1, the
vacuum transmission is switched back on.
• The OUT output is set once a workpiece is picked up securely, based on the vacuum value. This enables the
further handling process.
3.1.2 Depositing the Workpiece/Part (Blowing Off)
In blow off mode, the vacuum circuit of the valve 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 for versions with a display.
The valve provides three blow-off modes for selection:
• Externally controlled blow off
• Internally time-controlled blow off
• Externally time-controlled blow-off
3.2 Operating Modes
If the valve is connected to the supply voltage, it is ready for operation. This is the normal operating mode, in
which the valve is operated by the system controller.
The options for parameterizing the valve are very different depending on the version.
During the setup process, the user can:
• Control the valves manually using the manual auxiliary actuation for type "b"
• Use "Manual operation" mode for type "c"
• Use "Setup" mode (only via IO-Link) and "Manual operation" for type "i"

6.3.2 Instructions for the Pneumatic Connection
To ensure problem-free operation and a long service life of the valve, only use adequately maintained compressed
air and consider the following requirements:
• Use air or neutral gas in accordance with EN 983, filtered to 5μm, unoiled.
• Dirt particles or foreign bodies in the valve connections, hoses or pipelines can lead to partial or complete
malfunction.
1. Shorten the hoses and pipelines as much as possible.
2. Keep hose lines free of bends and crimps.
3. Use only pipes or hoses with the recommended inner diameter to connect the valve:
Use hoses with sufficient internal diameter...
on the compressed air side to ensure that the valve achieves its performance data. 2mm
on the vacuum side to avoid high flow resistance.
If the internal diameter is too small, the flow resistance and the evacuation times increase and
the blow off times are extended.
