On installation

Make sure the relevant system component is not under pressure or voltage
before assembling the product or when connecting and disconnecting plugs.
Protect the system against being restarted.

Lay cables and lines so that they cannot be damaged and no one can trip over
them.

Observe the connection symbols and connection designations on the ejector.

Only use the designated connection options, mounting holes, and mounting
material.

Before commissioning, make sure that all the connection seals and locks are
properly installed and undamaged to prevent fluids and foreign bodies from
penetrating the product.

Only use the following power supply for the components:
– 24 V DC PELV circuits in accordance with DIN EN 60204-1/IEC 60204-1.
– The PELV power source must be a safety isolation transformer in accordance

with IEC 61558-1 or IEC 61558-2-6, or a power source offering the same
degree of safety as a safety isolation transformer.

– Make sure that the power supply of the power pack is always less than

300 V AC (outer conductor – neutral wire).

In case of heavily contaminated vacuum/ambient air, use a VFC cup version
vacuum filter between the vacuum connection and the volumes to be evacuated.

During commissioning

Check that all the electrical and pneumatic connections are allocated or closed.
Only commission fully installed products.

When the supply voltage is switched on, output signals may change (discrete
signals as well as IO-Link signals). Depending on the machine's/system's
functionality, this may lead to severe personal injury or damage to equipment.

During operation

Do not use the ejector in areas that are not splashwater-proof.

Closed containers may explode due to compressed air. Closed containers may
implode due to vacuum.

Only operate the ejector with a silencer. Never look into the exhaust air stream of
the silencer.

The ejector emits acoustic noise. We recommend wearing ear protectors.

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.

Operating the product beyond the specified performance limits is not permitted.
Malfunctions and destruction may result.

No persons are allowed in the transporting area of the suctioned useful load.

With the machine/system in automatic mode, no persons are allowed in the
danger zone.

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.

Do not operate the ejector with a closed vacuum connection.

During cleaning

Never use solvents or aggressive detergents. Only clean the product using a
damp cloth. Only use water and, if necessary, a mild detergent.

Do not use high-pressure cleaners for cleaning.

During service and repairs

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.

About This Product

Product overview

Fig.

(ECD-IV) and

(ECD-LV) depicts the compact ejectors.

Assembly

Electrically connecting the ejector

Electrical connection is made via a 5-pin M12 plug that supplies the ejector with
power and includes the two input signals and the output signal. Inputs and
outputs are not galvanically isolated.

Use protective extra low voltage (PELV) only and provide for secure electrical
isolation of the operating voltage in accordance with EN 60204.

The maximum line length for the supply voltage and the signal inputs and outputs
is 30 m.

IO-Link operating mode

When operating the ejector in IO-Link mode (digital communication), only the supply
voltage and and the communication line must be connected to a controller either
directly or via intelligent connection boxes.
The communication line for IO-Link (C/Q line) must always be connected to an
IO-Link master port (point-to-point connection). The combination of several C/Q lines
on a single IO-Link master port is not possible.
Next to the basic functions of the ejector, such as suction, blow-off and feedback,
connecting the ejector via the IO-Link makes a large number of additional functions
available. These include:

Current vacuum value

Selection of four production profiles

Errors and warnings

Status display of the ejector system

Access to all parameters

Counter

Condition monitoring

Energy monitoring

Predictive maintenance

This way, all variable parameters can be directly read, changed, and rewritten on the
ejector by the superior control.
Evaluation of the condition and energy monitoring results allows the drawing of
direct conclusions about the current handling cycle and trend analyses.
The ejector supports the IO-Link revision 1.1. with four byte input data and two byte
output data.
It is also compatible with IO-Link masters after revision 1.0. This supports one byte
input data and one byte output data.
The exchange of process data between the IO-Link master and the ejector is cyclical.
The exchange of parameter data (non-cyclical data) takes place via the application
program in the control via the communication modules.

M12-plug 5-pin, type A (port class A)

Make the electrical connections for the ejector as follows, see Fig.

Make sure the relevant system part is not under voltage.

Lay the cables so as not to bend or crush them.

Connect the power supply to the ejector's electrical connection (

CAUTION

System is under voltage during operation

Working on the system under voltage can lead to injuries due to electric shock or
damage to the components.

Make sure that all relevant system parts are not under voltage before
performing work on the system.

Connect or disconnect plug connectors only if all relevant system parts are
without voltage.
