During operation
W
Do not use the ejector in areas that are not splashwater-proof.
W
Closed containers may explode due to compressed air. Closed containers may
implode due to vacuum.
W
Only operate the ejector with a silencer. Never look into the exhaust air stream of
the silencer.
W
The ejector emits acoustic noise. We recommend wearing ear protectors.
W
Do not draw in any hazardous dust, oil mist, vapor, aerosol, or similar as they will
reach the exhaust air and may result in poisoning.
W
Operating the product beyond the specified performance limits is not permitted.
Malfunctions and destruction may result.
W
No persons are allowed in the transporting area of the suctioned useful load.
W
With the machine/system in automatic mode, no persons are allowed in the
danger zone.
W
The trained personnel must also be familiar with the control concept of the
system. In this context, particular attention must be paid to redundant control
parts and feedback signals of the system.
During cleaning
W
Never use solvents or aggressive detergents. Only clean the product using a
damp cloth. Only use water and, if necessary, a mild detergent.
W
Do not use high-pressure cleaners for cleaning.
During service and repairs
W
Make sure that no line connections, ports and components are disconnected as
long as pressure and voltage are applied in the system. Protect the system
against being restarted.

Function Description

Vacuum generation (suctioning of workpiece)
The ejector is designed for handling parts using a vacuum in conjunction with
suctioning systems.
The ejector is actuated with electrical signals via the M12 plug. The "suction" signal
input activates and deactivates the Venturi nozzle. In the NO version, an applied
"suction" signal input deactivates the Venturi nozzle, while in the NC version it
activates the nozzle.
An integrated sensor detects the vacuum generated by the Venturi nozzle. This is
analysed by an electronics systems and shown in the display. The measured value
is used as a basis for the integrated air economizer and is also used to switch the
"Parts control" output.
In "suction" operating state, the ejector automatically regulates the vacuum.
The electronics switch off the Venturi nozzle when the switching point H1 set
by the user is reached.
With small volumes to be evacuated, there may be situations where the
vacuum is switched off far beyond the set switching point H1. This behavior
does not constitute an error.
On suctioned objects with leak-tight surfaces, the integrated non-return valve
prevents the vacuum from dropping. If the system vacuum drops below switching
point H1-h1 due to leakage, the Venturi nozzle switches on again.
The supply voltage is monitored by the electronics. If the supply voltage falls below
around 19 V, an error message appears to alert the user. Defined operation of the
ejector can no longer be guaranteed below this voltage threshold.
Furthermore, the maximum upper limit for the supply voltage of around 26 V is also
monitored. A display appears if this limit is exceeded.
Blow off (placing down the workpiece)
In "blow off" operating state, the vacuum circuit of the ejector is pressurized with
compressed air. This mode is used to ensure fast vacuum reduction and thus quick
placing of the workpiece. The "blow off" operating state can be actuated either
externally or internally.
With externally controlled blowing-off, the "blow off" operating state is activated via
the "blow off" signal input.
With internally controlled automatic blow-off, the "blow off" valve is automatically
actuated for a set time after leaving the "suction" operating state.
With externally controlled automatic blow-off, the "blow-off" valve is automatically
actuated for a set time after activation of the "blow off" signal input.
The ejector additionally features the "Manual operation" mode.
In this operating mode, suction and blow-off can be actuated via the keys on
the ejector. Refer to the section "Manual operation" for further information.
Operating modes
All ejectors in the ECS-IV series can be operated in two operating modes.
The operator can choose between the direct connection to inputs and outputs
(standard I/O = SIO) or a connection via the communication line (IO-Link).
In the basic operating state, the ejector always works in SIO mode
(standard I/O mode) but can be transferred to the IO-Link operating mode at any time
via an IO-Link master, and vice versa.

SIO operating mode
When operating the ejector in SIO mode, all input and output signals are connected
to a controller (PLC) either directly or via intelligent connection boxes.
In addition to supply voltage, this requires two input and one output signals to be
connected, which the controller uses to actuate the ejector.
This way, the ejector's basic functions such as "suctioning" and "blowing off" as well
as feedback can be used. In detail, this means:
Ejector inputs
W
Suctioning ON/OFF
W
Blowing off ON/OFF
Alternatively, you can waive use of the "blow off" signal if the ejector is operated in
the "internally time-controlled" blow-off mode. This allows for operation on a single
port in a configurable connection box (application 1 x DO und 1 x DI).
The display and operating elements are used to adjust all settings and read out the
internal counter.
IO-Link operating mode
The ejector can be operated in IO-Link mode for intelligent communication with
a controller.
IO-Link mode enables the ejector to be configured remotely and also allows for
energy and process control (EPC).
Energy and process control (EPC) covers:
W
Condition Monitoring (CM):
Monitors the device status to increase plant availability
W
Energy Monitoring (EM):
Monitors energy to improve the vacuum system's energy consumption
W
Predictive Maintenance (PM):
Allows for predictive maintenance to improve the performance and quality of
gripper systems
