ENERAL DESCRIPTION OF FUNCTIONS
V ACUUM GENERATION ( PICKING UP THE WORKPIECE )
The ejector is designed for vacuum handling of parts in combination with suction systems.
The Venturi nozzle is activated and deactivated via the suction signal input. In the NO version, the Venturi nozzle is deactivated when the suction input signal is present. In the NC version, the Venturi nozzle is activated when the suction input signal is present.
An integrated sensor records the vacuum generated by the Venturi nozzle. This is evaluated by an electronics system and serves as the basis for displaying the system states and switching the output.
The ejector has an integrated air-saving function. The ejector automatically regulates the vacuum while in suction mode. The electronics system switches the Venturi nozzle off when the switching point H1 set by the user is reached.
If small volumes are to be evacuated, the set switching point H1 might be exceeded considerably before the vacuum is switched off. This system behavior does not constitute an error.
When objects with dense surfaces are picked up, the integrated non-return valve prevents the vacuum from dropping. If leakage causes the system vacuum to drop below the switching point H1-h1, the Venturi nozzle is switched on again.
B LOW OFF ( DEPOSITING THE WORKPIECE )
In blow-off mode, the vacuum circuit of the ejector is supplied with compressed air. This ensures that the vacuum drops quickly, depositing the workpiece quickly as well. Blow-off mode can be controlled externally or internally.
When controlled externally, blowoff mode is activated by the “blow-off” signal input.
When controlled internally (automatic blow-off), the blow-off valve is actuated for a defined period after suction mode is exited.
The ejector also has a manual mode. In this mode, the ejector can be controlled using the buttons on the ejector’s foil keypad. See the “Manual mode” section for more details.

ENERAL FUNCTIONS
M ANUAL MODE
The output signals may change during set-up in manual mode.
Ensure that the machine or system does not start moving as a result.
Personal injury or damage to the ejector could result.
Starting manual mode always switches the ejector to “pneumatically OFF” mode.
In other words, starting manual mode interrupts an active suction process.
Danger due to falling parts.
In manual mode, the pick-up and blow-off ejector functions can be controlled independently of the higher-level controller using the buttons on the operating panel.
In this operating mode, the H1 and H2 LEDs both flash.
A CTIVATING MANUAL MODE
Activate manual mode as follows:
Press and hold the and buttons together for more than 3 seconds
M ANUAL SUCTION
In manual mode, suction is activated by pressing the button. Exit suction mode by pressing the button again or by pressing the button.
If the air-saving function is activated this is also activated in manual mode.
M ANUAL BLOW OFF
Blow-off mode is activated in manual mode by pressing the remains active as long as the button is pressed.
button. This mode
D EACTIVATING MANUAL MODE
Exit manual mode using the button.
The ejector also exits manual mode when the statuses of the external signal inputs change.
This automatic exiting of manual mode due to changes in external signals can cause the object being handled to move (due to suction or blow-off).

M ONITORING THE SYSTEM VACUUM
S CHMALZ SCPS 2
Every ejector has an integrated sensor for monitoring the current system vacuum. The vacuum level provides information on the process and has an effect on the following signals and parameters:
Threshold value LED H1
Threshold value LED H2
Signal output H2
C ONTROL FUNCTION
This ejector function allows you to conserve compressed air. Vacuum generation is interrupted once the configured threshold value H1 is reached. If leakage causes the vacuum to fall below the hysteresis threshold H1-h1, vacuum generation resumes.
The control function can be deactivated by setting the threshold value for H1 to “Max.”.
B LOW OFF MODES
E XTERNALLY CONTROLLED BLOW OFF
The blow-off valve is controlled directly via the blow-off signal input. The ejector switches to blow-off mode for as long as the signal is present.
I NTERNALLY TIME CONTROLLED BLOW OFF
The “Blow-off” valve is automatically activated for the time period set as soon as the ejector leaves the “Suction” mode. This function makes it possible to save an output on the controller.
The time-controlled blow-off is activated by setting a value greater than zero for the blow-off time.
S IGNAL OUTPUT
The ejector has a signal output.
O UTPUT FUNCTION
The signal output is a normally open (NO) contact and cannot be changed.
The signal output is switched on or off when the system vacuum is higher or lower than the relevant threshold value.
3-16
S CHMALZ SCPS 2
V ACUUM UNIT
The vacuum level in the LED bar is shown as a percentage of the maximum possible vacuum.
If the vacuum is outside the permitted range, the LED next to this bar will flash rapidly.
That means the LED flashes “10%” when overpressure is applied.
O PERATING VOLTAGE DISPLAY
In operating modes in which no LEDs are activated, the “Max” LED will light up briefly. This indicates an operating voltage.
L OCKING THE KEYPAD
Pressing the and keys at the same time locks the keypad. Pressing both keys again unlocks the keypad.
S ETTING THE BLOW OFF VOLUME FLOW
+
-
There is a valve screw below the vacuum connection (2). This valve screw can be used to set the blow-off volume flow.
Turning the screw clockwise reduces the volume flow. Turning the screw counterclockwise increases the volume flow.
The valve screw is equipped with a stop on both sides.
Do not turn the valve screw past the stops. A minimum volume flow of approx.
10% is always necessary for technical reasons.
The blow-off volume flow can be set between 10% and 100%.

During operation of the ejector, all input and output signals are connected to a controller, either directly or using intelligent terminal boxes.
For this purpose, not only the supply voltage but also two input signals and one output signal should be connected to allow the ejector to communicate with the controller.
With these connections, the basic functions of the ejector can be used, including suction, blow-off and feedback signals. The individual connections are as follows:
Ejector inputs Ejector output
Suction ON/OFF
Blow-off ON/OFF

P NEUMATIC CONNECTION
Use only well-maintained compressed air (air or neutral gas according to EN 983, filtered to 5 µm, oiled or unoiled).
High-quality compressed air is important to ensure a long service life for the ejector.
Dirt particles or foreign bodies in the ejector connections, hoses or pipelines can lead to partial or complete ejector malfunction.
Hoses and pipelines should be laid such that distances are minimized.
If the internal diameter on the compressed air side is too small, insufficient compressed air will be supplied. This prevents the ejector from performing as specified in the performance data.
Excessive flow resistance occurs if the internal diameter on the vacuum side is too small. This leads to both a reduction in suction capacity and increased evacuation times. Blow-off times are also lengthened.
Hose lines must be laid without bends or crimps.
Only use hoses or pipes with the internal diameters recommended for the ejector. If this is not possible, use the next largest internal diameter.

ENERAL MAINTENANCE
E XTERIOR SOILING
Remove dirt on the exterior of the device with a soft cloth and soap suds (max. 60°C). Ensure that the silencer and the controller are not soaked with soap suds.
S ILENCER
Because it is open, the silencer may be exposed to high levels of dust, oil, etc., which may dirty the silencer to the point of reducing the suction capacity. If this happens, it must be replaced. Cleaning is not recommended due to the capillary effect of the porous material.
PRESS IN FILTERS
The vacuum and compressed air connections contain press-in screens.
Over time, dust, chips and other solids can become deposited in the filters.
If you notice that the performance of the ejector system has declined, simply replace the screens.
Do not operator the ejector system without press-in screens! This can damage the ejector system.
