1 SAFETY INFORMATION
IMPORTANT SYMBOLS
Danger Danger
Identifies a direct risk of danger. If it is not avoided, death and
serious injuries may result.
Caution Caution

or minor injuries may result.

GENERAL SAFETY INFORMATION
These operating instructions contain important information on using the
ejector system. Please read the operating instructions thoroughly and keep
them for later reference.
Compressed air could cause closed containers to explode. A vacuum could
cause closed containers to implode. Using the vacuum generator results in
noise. Ear protection may be worn.
This device is not intended for use with hazardous dust, oil mist, vapours or
aerosol. If drawn in, these materials will enter the exhaust air and may result
in poisoning. Always use suitable and permitted vacuum filters.
Use only the connections, attachment holes and attachment materials that
have been provided.
Carry out mounting/removal only when the device is in an idle,
depressurised state.
Components may be installed only by qualified specialist personnel who are
trained and familiar with:
The most current safety regulations and requirements with respect to
installing components and controllers in devices, machines and systems (for
solenoid valves, push switches, electronic controllers, etc.)
As well as their required electrical control, e.g. redundancies and, if
required, response messages (for solenoid valves, pressure switches,
electronic controllers, etc.)
Do not sit or stand in the area in which the picked up payload is transported.
INTENDED USE
The ejector system is used to generate a vacuum. The device can be used to
evacuate suction pads for holding payloads, for example, or to evacuate other
volumes. Air or other neutral gases in accordance with EN 983 are approved as
media for evacuation.
The ejector system is not suitable for transporting (through-suction) of liquids,
gases and/or granulates.
Ejectors must not be used to fill pressurised containers, for driving cylinders,
valves or pressure-operated function elements.

MECHANICAL FUNCTION DESCRIPTION
The ejector block consists of six working circuits, which can be controlled
independently of one another.
By applying the main compressed air [2] and controlling the appropriate working
circuit using the ASi bus, the main compressed air is routed through at the
vacuum connections [12] and the ejector blows for as long as the signal is
present. When the signal is reset using the ASi bus, a partial vacuum is created
at the vacuum connection [12] and various work pieces can be lifted.
After the desired working circuits are activated, the alternate compressed air
connection [3] can be pressurised. This causes the alternate compressed air to
be routed through to the appropriate connections for external cylinders [11], in
addition to the working circuits that have already been activated. Only the
cylinders of the working circuits which have already been turned on are
activated.
By activating a working circuit again using the ASi bus, the ejector at the
corresponding circuit is switched to blow-off mode. Cylinders which have
already been activated are not affected.
The activated circuits are reset by deaerating the main compressed air line [2].
This resets all working circuits and cylinders.
Note: The alternate compressed air [3] can be turned on only after the
appropriate working circuit has been activated using the ASi bus.
ELECTRONIC FUNCTION DESCRIPTION
The device is turned on electrically using an ASi bus system. There are two ASi
slaves integrated in the ejector system for this purpose. Using these ASi slaves,
the valves of the six working circuits on the ejector block can be activated and
the six integrated vacuum sensors (optional) can be queried.
This is connected using two ASi plug connectors on the top of the ejector
system. The yellow dual-conductor flat cable is for the ASi bus (ASI) [7] and the
black dual-conductor flat cable is for the auxiliary power supply (AUX) [6].
LEDs [10] that display the status of the ASi slaves are located on the front of
the ejector block.
The ASi slaves can be addressed using the addressing jacks [8], which are
located on the front of the ejector block.

DISPLAY ELEMENTS
LEDs [10] that display the status of the ASi slaves are located on the front of
the ejector block. The LED assignment is laid out on the printed-circuit board
and on the cover.
For each ASi slave, there are LEDs for ASi voltage, ASi communication, the
auxiliary power supply, the inputs and the outputs.
