About This Product

Product Overview 1
Fig. 1 shows the compact ejector ECD-SV.

Function description
Vacuum generation (suctioning of the 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 evaluated via an electronic circuit and is used as the basis for indicating the system states and actuating the output.
The ejector features an integrated air economizer function. In the “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.

Blow off (placing down the workpiece)
In the “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 an internally controlled automatic blow-off, the “blow-off” valve is automatically actuated for a set time after leaving the “suction” operating state.
The ejector additionally features the “Manual operation” mode.
In this operating mode, the keys on the membrane keypad can be used to actuate the ejector. See also the section “Manual operation”.

Assembly 2

The ejector may only be commissioned after it has been installed in the machine/ system for which it is intended.
During ejector operation, all input and output signals are connected to a controller either directly or via intelligent connection boxes.
In addition to the supply voltage, this requires two input and one output signal to be connected, via which the ejector communicates with the controller.
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 Ejector output

■ Suctioning ON/OFF
■ Blowing off ON/OFF| ■ Feedback H2

All parameter settings are made via the display and operating elements.
Assembling the ejector 4 1
The ejector can be mounted either with screws or by using a hat rail clamp, see Fig. 4 and 1 . See figure for dimensions  2.

When mounting the fastening screws, we recommend using washers.

Connecting the ejector pneumatics 5

CAUTION
The system is under pressure during the operation
Working on the system under pressure can lead to injuries and damage to property.

  •  Depressurize all relevant system parts prior to performing work on the system.
  • Use only compressed air from an appropriately maintained system (air or neutral gas in accordance with EN 983, filtered to 5 μm, oiled or oil-free).
  • Dirt particles or foreign bodies in the ejector connection or tubing or pipelines may impair the ejector’s function or lead to a malfunction.
  • Route tubing and pipelines as short as possible.
  • If too small inside diameters are selected for the compressed air end, the compressed air supply will be insufficient. As a result, the ejector will not achieve its specified performance.
  • If the inside diameter selected for the vacuum end is too small, this will cause an excessively high flow resistance. This will in turn decrease the suction capacity and increase the suction time. Blow-off times will also increase.
  • Use only the tubing and pipeline inside diameters recommended for the ejector.
  • If this is not possible, use the next higher diameter.

Make the pneumatic connection for the ejector as follows, see Fig. 1 :

  1. Make sure the relevant system part is not under pressure.
  2. Lay the tubes so as not to bend or crush them.
  3. Connect the compressed air tubing with the compressed air connection (8) and the vacuum tubing with the vacuum connection (4).

Electrically connecting the ejector

CAUTION
The 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.
  • The 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 a 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.

Commissioning and Operation

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.

  • 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.
  • Do not connect or disconnect plug connectors under voltage.

WARNING
Severe personal injury or property damage due to moving machine/system parts
When switching on the supply voltage, the signal output may change. Depending on the machine’s functionality, the machine/system may be put into motion.

  • Make sure that no persons are in the transporting area when you switch on the machine/system.

Operating states 6 7
The ejectors are distinguished into NO (normally open) and NC (normally closed) based on their basic position when no voltage is applied.
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.
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.
Parameterization
Ejector parameterization is always done from within automatic mode.
General functions

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.

  • Never look into vacuum openings, neither suctioning nor not suctioning (e.g. vacuum connections or connected vacuum cups).
  • Never look into or enter the exhaust air stream.

Manual operation

WARNING
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.

  • Make sure that the machine/system is not put into motion and that no persons are in the transporting area when you are setting up manual operation.
  • Make sure that there are no control commands coming from the PLC during manual operation, and put the ejector into automatic mode as a result.

Dropping useful load due to lacking vacuum
Starting manual operation always results in the “pneumatics OFF” operating state, i.e. active suctioning is interrupted by manual operation. The useful load may therefore drop.

  • 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.
Activating “Manual operation”

  •  To activate “Manual operation” mode, simultaneously press and hold the and  buttons for > 3 s.
  • Manual suctioning
  • To activate the “suction” operating state in “Manual operation” mode, press the button.
  • To exit the “suction” operating state again, press the button or the button once again.

If the air economizer has been switched on, it will also be active in “Manual operation” mode.
Manual blowing off

  • To activate the “blow off” operating state in “Manual operation” mode, Press and hold the button .
  • To exit the “blow off” operating state, release the button .

WARNING
The danger of injury due to moving objects
Automatic exiting of manual operation by changes to external signals can put a handling object in motion by suctioning or blowing off.

  • Make sure that no objects will be moved and no persons are in the transporting area when you are exiting manual mode.
  • Press the button to exit the “Manual operation” mode.

The “Manual operation” mode is also exited by status changes of the external signal inputs.

Monitoring the system vacuum
Each ejector features an integrated sensor for monitoring the current system vacuum. The vacuum level provides information about the process and influences the following signals and parameters:

  • Threshold value LED H1
  • Threshold value LED H2
  • Signal output H2

Control function
This ejector function provides the opportunity of saving compressed air. When the set switching threshold H1 is reached, vacuum generation is interrupted. If the vacuum drops below the hysteresis threshold H1-h1 due to leakage, vacuum generation is resumed.
The control function can be deactivated by setting the threshold value for H1 to “Max.”.

Blow-off modes
Externally controlled blowing off
The “blow off” valve is directly actuated via the “blow off” signal input. The ejector will blow off as long as the signal is present.
Internally timed blowing off
The “blow off” valve is automatically actuated for the set time when exiting the “suction” operating state. This function saves an output on the controller.

Timed blowing-off is activated by setting a value greater than zero for the blow-off time.

Signal output
The ejector features a signal output.
Output function
The signal output is a normally open contact that cannot be readjusted.
If the system vacuum exceeds or falls below the associated threshold value, the signal output is switched on or off respectively.
Vacuum unit
The LED bars indicate the vacuum level as a percentage of the maximum possible vacuum.
If the vacuum is outside the permissible range, the adjacent LED flashes at a high frequency. I.e. if overpressures are applied, the 10% LED flashes.
Supply voltage display
In operating states where no LED is active, the Max. LED repeatedly flashes briefly.
It indicates the available supply voltage this way.
Button lock-out

  • In order to lock the buttons, press the buttons and simultaneously.
  • To cancel the button lock-out, press the two buttons once again.

Setting the blow-off volume flow

Below the vacuum connection, there is a flow control screw for setting the blow-off volume flow.

  • Turn the flow control screw clockwise (to the right) in order to reduce the volume flow.
  • Turn the flow control screw counterclockwise (to the left) in order to increase the volume flow.
    The flow control screw has a stop on both sides.

Do not turn the flow control screw beyond its stops! Due to technical reasons, a minimum volume flow of approx. 10% is always required. The blow-off volume flow can be set to a value between 10% and 100%.

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 firmly fitted.
  2. Enter the desired parameters.

Service and Repairs

External contamination

NOTICE
Damage and disruptions due to penetrating fluids or contact with aggressive media
Penetrating fluids and the use of solvents and aggressive cleaning agents can lead to damage and disruptions.
In this case, a reliable ejector function can no longer be guaranteed.

  • Only clean the ejector with a damp, lint-free cloth.
  • Only use water and, if necessary, a mild detergent for cleaning.
  • Make sure that the silencer and the controller are not soaked in fluid.
  • Do not use a high-pressure cleaner.

Silencer

NOTICE
Damage due to excessive force
Exerting excessive force when tightening the mounting screws can lead to damage to the housing.

  • Observe the maximum torque of 0.5 Nm when tightening the mounting screws on the silencer module.

We recommend that you also replace the damping plate when exchanging the silencer insert.
The open silencer can become soiled if exposed to heavy contamination by dust, oil, etc., and thus reduce the suction capacity. It should be replaced in this case. Due to the capillary effect of the porous material, cleaning is not recommended.

Press-fit screens

NOTICE
Damage to the ejector system due to missing press-fit screen
Fluids and foreign objects could penetrate and destroy the ejector.

  • Do not operate the ejector system without press-fit screens.

Press-fit screens are installed in the vacuum and compressed air connections.
Over time, dust, chips, and other solid matter can deposit in these screens.
If the ejector system performance noticeably drops, the screens can easily be replaced.
