11 Operation
11.1 Operation via IO-Link
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 master
(point-to-point connection). It is not possible to connect multiple C/Q lines to 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:
•
Device Data
•
Device status
•
The current vacuum level
•
Choice of four production profiles (production setup profiles P0 to P3)
•
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.
11.2 General Preparations
WARNING
Extraction of hazardous media, liquids or bulk material
Personal injury or damage to property!
4
Do not extract harmful media such as dust, oil mists, vapors, aerosols etc.
4
Do not extract aggressive gases or media such as acids, acid fumes, bases, biocides, dis-
infectants or detergents.
4
Do not extract liquids or bulk materials, e.g. granulates.
Always carry out the following tasks before activating the system:
1. Before each use, check that the safety features are in perfect condition.
2. Check the ejector for visible damage and deal with any problems immediately (or notify your super-
visor).
3. Ensure that only authorized personnel are present in the working area of the machine or system and
that no other personnel are put in danger by switching on the machine.
There must be no people in the system danger area while it is in operation.
