Integrated 2 stages large sizeejector. The simple and modular
design of the pump makes easy
for the user to access the ejector
for maintenance and cleaning
operations. It is possible to choose
the best ejector for a speciﬁc
application by selecting one of
the following ejector types: highﬂow (HF), high vacuum (HV) or low
supply pressure (LP).

...and modular
The EJ-XPRO pump series can be used in stand-alone applications or connected in series up to 4 units in total bysimply acting on the special embedded grub screw. This also makes easy the replacement of a unit in case of need.
For a system composed of multiple units in series, it’s possible to supply pressurized air by a single input channel andeventually convey the exhausts by using a special exhaust adaptor.

> Connection for manifold
mount, maximum 4 units.
> Flexible installation.
> Possibility to mount andremove the single units.

PART PRESENTENERGY SAVING

Speciﬁc display area is colored in yellow when the object
is handled.

Allows to save up to 90-95% of compressed air at eachcycle.

BLOW-OFFAUTOMATIC ENERGY SAVING

Two types of blow-off selectable from the menu:

Automatically identiﬁes the optimal vacuum thresholds
levels at each cycle regardless of the type of material.

• INPUT: The blow-off is electrically activated by pin 6• AUTO: At each automatic cycle, the blow-off ﬂow will

AUTO EXCLUDE

be performed for the duration set in the menu.

In case of signiﬁcant leakage in the system, this function
disables the ES to protect the valves and their lifetime.

For both models, the blow-off air ﬂow rate is mechanicallyadjustable.

Maintenance and replacement of ejector
The mechanical design of EJ-XPRO pump series allows for an easy access tothe vacuum ejector’s installation area. By simply removing the frontal display
subsystem, the user can directly extract the ejector for easy replacement orcleaning operations. It’s also possible to change the ejector type choosing
between 3 different models: HF (optimizing the vacuum level), HV (maximizingthe vacuum grade) and LP (optimizing the consumption air ﬂow by operating
the pump with a low pressure supply level).

Energy saving (ES)ES high
ES lowvacuum

If the function is enabled with the corresponding menu item, and provided
there are no leakages, the energy saving feature allows considerable savingsof compressed air by switching off vacuum generation and retaining thevacuum in the circuit (this must not be considered as a safety system inthe event of compressed air/electricity supply interruption). The vacuum isretained by means of a valve on the cartridge and the blow-off function must
therefore be activated in order to release the handled object.
The ES low and ES high thresholds must be set through the menu.

Automatic energy saving (AES)

vacuumIf ENERGY SAVING is enabled in the menu, the function AES is activated by
setting the ES low and ES high values to -98 kPa and -99 kPa respectively.
It allows the automatic setting of energy saving trigger thresholds for eachcycle, based on the maximum vacuum level attainable on the material being
handled.

If the object being gripped is too porous, or if there are any leaks in the vacuum
circuit to an extent that makes it impossible to use the ENERGY SAVINGfeature, the AUTO EXCLUDE function will be activated to create maximum
vacuum.
In particular, if enabled with the corresponding menu item, the function
intervenes by excluding the ES function in all those cases in which there
is a high number of reactivations of the vacuum valve in a short time. Thisfunction also eliminates frequent activations, extending the life of the vacuum
solenoid valve.
≥ 2 reactivations in 3 seconds: the pump is activated to provide continuousvacuum.
< 2 reactivations in 3 seconds: pump continues to run with ES.

V DC

The EJ-XPRO circuit board integrates several advanced features such as a
PWM to power supply the electro-valves. This allows for several beneﬁts like:• a fast response time of the system, by providing full electrical power whenvalves are initially activated• optimized power consumption and reduced heat generation• extended lifetime of the components
ms

Automatic blow-off
The EJ-XPRO pump series offers an integrated blow-off
channel for an easy and quick release of the part handled oncethe vacuum is removed. The blow-off type can be conﬁgured
manually by navigating the digital menu of product and selecting
a blow-off from input digital signal or an automatic blow-off.
With a blow-off from input signal, the blow-off is triggered by
an external digital signal provided at a speciﬁc pin of the M12connector. With an automatic blow-off selection, the EJ-XPRO
pump activates the blow-off autonomously after interruption of
the vacuum generation signal. In this case, it’s also possible
to deﬁne the duration of the blow-off by setting a dedicatedparameter of the digital menu.

Enhanced blow-off
The front panel of the EJ-XPRO pump series hosts a slottedhead screw by which the user can manually adjust the intensity(ﬂow-rate) of the blow-off.
