Planning, SIO mode
All process signals have to be wired in parallel for operating the ejector in SIO mode.
Consequently, three lines are required per ejector for the process signals.

Commissioning and Operation

Severe personal injury or property damage due to moving machine/system parts
When the supply voltage is switched on, 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.
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.

WARNING
CAUTION
Operating states
Automatic
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 parameterization is always performed in automatic mode.
Manual
The buttons on the ejector can be used to switch the operating state from automatic
operation to "Manual operation".
General functions
1
In SIO mode, the following functions can be adjusted directly on the ejector.
:
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.
Manual operation
Personal injury or property damage due to moving machine/system parts
When setting up in manual operation mode, output signals may change and
external signals (coming from the PLC via the M12 plug) may end manual
operation, which will cause the machine/system to be put into motion.
O Make sure that the machine/system is not put into motion and no persons are
in the transporting area when you are setting up manual operation.
O Make sure that there are no control commands coming from the PLC during
manual operation, and putting the ejector into automatic mode as a result.
Dropping useful load due to lack of vacuum!
Starting manual operation always results in the "pneumatics OFF" operating
state, i.e. active suctioning is interrupted by manual operation. Useful load may
therefore drop.
O Make sure that no persons are located under the useful load in the
transporting area.
In manual operation, the "suction" and "blow off" ejector functions can be controlled
using the control panel buttons.
The two LEDs "H1" and "H2" flash in this operating mode.
Because the valve protection function is deactivated in manual operation, this
function can also be used to locate and repair leaks in the vacuum circuit.
Activating "Manual operation"
O To activate "Manual operation" mode, simultaneously press and hold the
buttons for > 3 s.
[-M-] appears during actuation
The current process status is retained when manual operation is first actuated.
Manual suctioning
O To activate the "suction" operating state in "Manual operation" mode, press the
button.
O To exit the "suction" operating state again, press the
once again.
If the air economizer has been switched on, it will also be active in "Manual
operation" mode.
The valve protection function is not active in "Manual operation" mode.
Manual blow-off
O To activate the "blow off" operating state in "Manual operation" mode, press and
hold the button
O To exit the "blow off" operating state, release the button
