9.3.2 Instructions for the Pneumatic Connection
Use only screw unions with cylindrical G-threads for the compressed air and vacuum connection!
To ensure problem-free operation and a long service life of the ejector, only use adequately maintained
compressed air and consider the following requirements:
• Use of air or neutral gas in accordance with EN 983, filtered 5 μm, oiled or unoiled.
• Dirt particles or foreign bodies in the ejector connections, hoses or pipelines can lead to partial or
complete ejector malfunction.
1. Shorten the hoses and pipelines as much as possible.
2. Keep hose lines free of bends and crimps.
3. Only use a hose or pipe with the recommended internal diameter to connect the ejector, otherwise
use the next largest diameter.
On the compressed air side, ensure that the internal diameter is wide enough for the ejector to
achieves its performance data (8 mm).
On the vacuum side, ensure that the internal diameter is wide enough to avoid high flow resistance
(9 mm). If the internal diameter is too small, the flow resistance and the evacuation times increase
and the blow off times are extended.
Internal diameters based on a maximum hose length of 2 m.

For longer hose lengths, the cross-sections must also be larger.
9.4 Operation Using IO-Link Class B
When the ejector is operated in IO-Link mode (digital communication), the supply voltages, the ground
and the communication cable for the IO-Link (C/Q cable) are connected directly to the IO-Link class B mas-
ter (point-to-point connection). Several C/Q wires cannot be connected to just a single IO-Link master
port.
Connecting the ejector via the IO-Link provides access to a number of additional ejector functions along-
side the basic functions of suction, blow-off, feedback, etc. These additional functions are:
• The current vacuum level
• Selection of four production profiles
• Errors and warnings
• Ejector system status display
• Access to all parameters
• Functions for energy and process control
So that all the modifiable parameters can be read directly via the higher-level controller, modified and
written back to the ejector.
Evaluation of the condition monitoring and energy monitoring results allows you to draw direct conclu-
sions regarding the current handling cycle and perform trend analysis. The ejector supports the IO-Link re-
vision 1.1 with four bytes of input data and two bytes of output data. It is also compatible with IO-Link
masters that use the 1.0 revision. In this case, one byte of input data and one byte of output data are sup-
ported. The exchange of process data between the IO-Link master and the ejector is cyclical. Parameter
data (acyclical data) is exchanged by the user program in the controller using communication modules.
