Configuration server
Since revision 1.1 the IO-Link protocol contains an automatism for data migration in
case of a device replacement. In this mechanism, which is called Data Storage the
IO-Link master mirrors all setting parameters of the device in a separate non-
volatile storage. When replacing the device by a new one of the same type, the setting
parameters of the old device are automatically stored in the new device by the
master.
For this to be possible with ejector ECD-IV/ECD-LV it must be operated on a master
of the IO-Link revision 1.1 or higher and the data storage feature activated in the
configuration of the IO-Link port.
While a detailed description of the data storage mechanism cannot be provided here,
the following practical notes may be of interest:
W
The mirroring of the device parameters into the master takes place automatically
if the device is parameterized with an IO-Link configuration tool, such as e.g.
S7-PCT.
W
Parameter changes that are implemented on the device in the user menu are
also automatically mirrored in the master.
W
Parameter changes that are implemented by a control program with the help of
a function module are not automatically mirrored in the master. In this case,
mirroring can be activated manually by carrying out an ISDU write access on the
“system command” parameter via the command “ParamDownloadStore“
(numerical value 5).
W
In order for the data transfer to take place in the correct direction it must be
ensured that the new device is in the state on delivery before connecting it to the
IO-Link master. This can be achieved anytime through the return to state on
delivery function, e.g. via the operating menu.
5 Commissioning and Operation
Operating states
When the ejector is connected to the supply voltage, the ejector is ready for operation
and is in automatic mode. This is the normal operating state, in which the ejector is
operated via the system controller (PLC).
Ejector configuration is always performed in automatic mode.
Manual
In addition to automatic operation, you can also actuate the buttons in the membrane
keypad to change the ejector's operating state and switch to manual operation.
Information regarding the operation of the compact ejectors ECD-IV
or ECD-LV in the standard I/O mode (SIO mode) are included with the
product (compact ejector ECD-IV, R412025990 or compact ejector ECD-LV,
R412025991) and is available in the media centre at
www.aventics.com/media-centre/.
WARNING
Severe personal injury or property damage due to moving machine/system
parts
When switching on the supply voltage or inserting the M12 push-in fittings,
the signal output may change. Depending on the machine's functionality, the
machine/system may be put into motion.
O
Make sure that no persons are in the transporting area when you switch on the
machine/system.
CAUTION
Personal injury or property damage caused by non-compliance with specific
technical rules
Operating the ejector system without power packs and without complying with
standard EN 60204 can result in personal injuries and damage to the system and
the connected components.
O
Only operate the system using power packs with protective extra-low voltage
(PELV) and safe electric isolation of the supply voltage in accordance with
EN 60204.
O
Do not connect or disconnect plug connectors under voltage.

Commissioning
The ejector may only be commissioned after it has been installed in the machine/
system for which it is intended.
First-time commissioning
1. Make sure that all electrical and pneumatic connections of the ejector are
correctly connected and are firmly fitted.
2. Enter the required menu settings (basic settings, configuration menu, system
menu, and user menu).
3. Switch on the operating voltage.
4. Switch on the operating pressure.
Recommissioning after a downtime
1. Make sure that all electrical and pneumatic connections of the ejector are
correctly connected and are firmly fitted.
2. Switch on the operating voltage.
3. Switch on the operating pressure.
Correctly set up IO-Link communication is signaled by an illuminated
communication LED on the IO-Link master port.
Actuate the
button on the ejector to display the operating mode of the ejector.
A typical handling cycle is divided into the three steps of suctioning, blowing off and
idle state. In order to check whether sufficient vacuum has been built up, output 2 is
monitored during suctioning.
Information regarding the menu structure of the compact ejectors ECD-IV or ECD-LV
are included with the product (compact ejector ECD-IV, R412025990 or compact
ejector ECD-LV, R412025991) and is available in the media centre at
www.aventics.com/media-centre/.
6 Parameters and functions
General functions
the following functions can be adjusted via the input screen in IO-Link mode or
without IO-Link mode directly on the ejector in SIO mode.

WARNING
Open vacuum/exhaust air connections and vacuum cup
Risk of injury by suctioning of eyes or other parts of the body.
Risk of injury due to exhaust air and any other parts and debris that may have
been drawn in being emitted from the exhaust air connection at high speed.
O
Never look into vacuum openings, neither suctioning or not suctioning
(e.g. vacuum connections or connected vacuum cups).
O
Never look into or enter the exhaust air stream.
