The currently selected data set is displayed in the parameter data under “Production Setup”. This data set
corresponds to the current parameters the ejector is working with, which can be viewed using the menu.
Displaying the parameter data set (P-0 to P-3) currently in use during IO-Link operation:

The parameter data set (P-0 to P-3) currently in use is briefly shown in the display.
In the default setting, the P-0 production setup profile is selected.
Then menus can only be used to adjust the profile that is currently selected via IO-Link.
7.18 Energy and Process Control (EPC)
In IO-Link mode, the energy and process control (EPC) function is available. It is subdivided into three
modules:
•
Condition monitoring (CM): Condition monitoring to increase system availability
•
Energy monitoring (EM): Energy monitoring to optimize the vacuum system’s energy consumption
•
Predictive maintenance (PM): Predictive maintenance to increase the performance and quality of the
gripping systems
7.18.1 Condition Monitoring (CM) [0x0092]
Monitor Valve Switching Frequency
When the air saving function is activated and there is a high leakage level in the gripping system, the
ejector switches between the Suction and Suction Off states very frequently. The number of valve switch-
ing procedures thus increases rapidly within a short time.
To protect the ejector and increase its service life, the ejector automatically deactivates the air saving
function and switches to continuous suction if the switching frequency > 6/3 s (more than 6 switching op-
erations within 3 seconds). In this case the ejector remains in the Suction state.
It also issues and warning and sets the corresponding condition monitoring bit.
