If it is not avoided, slight or minor injuries may result. Danger! This symbol indicates an immediate hazard. If it is not avoided, death or serious injuries may result.
SCPS CH MALZ Specialist personnel must be familiar with current safety rules and requirements. For example, these apply to the use of components such as solenoid valves and pressure switches as well as to controllers used in devices, machines and systems. ...
SCPS CH MALZ NSTALLATION AND OPERATION For safe installation and trouble-free operation, please observe and comply with the follo- wing points: The ejector may only be operated using power supply units with protected extra-low voltage (PELV). The system must incorporate safe electrical cut- off of the power supply in compliance with EN60204.
SCPS CH MALZ RODUCT VERVIEW ENERAL DESCRIPTION OF FUNCTIONS 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 ver- sion, the Venturi nozzle is deactivated when the suction input signal is present.
SCPS CH MALZ 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, blow-off mode is activated by the “blow-off”...

SCPS CH MALZ ENERAL FUNCTIONS 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. In manual mode, the “Suction” and “Blow-off” ejector functions can be controlled indepen- dently of the higher-level controller using the buttons on the operating panel.
SCPS CH MALZ UP MODE Similar to manual mode, set-up mode can be used to locate and rectify leaks in the vacu- um circuit because the valve protection function is deactivated and because the control function is not deactivated even if the control frequency increases. In this operating mode, the H1 and H2 LEDs both flash.
SCPS CH MALZ ONTROL FUNCTION With this function, the ejector allows you to save compressed air or prevent a too powerful vacuum from being generated. 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.
SCPS CH MALZ [dCS = oFF] If the function is selected, the ejector switches to continuous suction mode if the leakage rate and the valve switching frequency are too high. [dCS = on] With the setting, continuous suction is deactivated and the ejector continues in control mode despite high leakage and a control frequency greater than 6/3 s.
SCPS CH MALZ [tbL] The length of the blow-off time is set in the main menu. This menu item is [-E-] hidden in the operating mode. The number displayed indicates the blow-off time in seconds. Blow-off times from 0.10 s to 9.99 s can be set. IGNAL OUTPUT The ejector has a signal output.
SCPS CH MALZ NCH OF The vacuum values are displayed in inHg. The setting for this unit is [-iH]. [uni] The function can be set using the configuration menu under the menu item or can be set via IO-Link. Selection of the vacuum unit only affects the display of the ejector.
SCPS CH MALZ FOR WRITE PROTECTION A PIN code can be used to prevent the parameters from being changed using the user menu. The current settings are still displayed. The PIN is set to 000 on delivery, meaning access to the parameters is not locked. A valid PIN between 001 and 999 must be entered in order to activate the write protection.
SCPS CH MALZ ESET TO FACTORY SETTINGS This function restores the ejector configurations of the initial setup and the settings of the active production setup profile to the factory settings. This function does not affect counter readings, the zero-point adjustment of the sensor or the “Application Specific Tag”...
SCPS CH MALZ OLTAGE MONITORING All ejector types have an internal voltage monitor. If the supply voltage falls below the permitted threshold, the ejector has the E07 error status. This appears in the display, and prevents menu operation and response to the signal inputs. The component check output retains its normal functionality.
SCPS CH MALZ 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.

SCPS CH MALZ PERATING All ejectors of the SCPSi series have two operating modes. Users can choose between direct connection to inputs and outputs (serial I/O = SIO mode) or connection through the communication line (IO-Link). By default, the ejector always runs in SIO mode, but it can be switched in and out of IO- Link mode by an IO-Link master at any time.
The lines for the power supply, the signal inputs and the signal output can have a ma- ximum length of 30 meters. Direct connection Connection via I/O box Schmalz connection lines may be Schmalz connection distributors and Schmalz used to connect the ejector directly connection lines may be used to connect the ejector to the controller.

CH MALZ For the devices in the SCPSi series, the IODD is available to download in two versions from www.schmalz.com: IODD in accordance with the revision 1.1, for use with current IO-Link masters The full range of functions is available with 4 bytes of input data and 2 bytes of output data ...
SCPS CH MALZ ROCESS DATA Once communication with an IO-Link master has been established, the master begins the automatic cyclic exchange of process data. The master receives new process output data (PDO) from the controller or field bus level and passes this on to the ejector for control. The feedback and measured values from the ejector are collected from the master as pro- cess input data (PDI) and forwarded to the system controller.
See the separate document, “SCPSi Data Dictionary”, to find out which parameter data is offered by the ejector SCPSi and how this data is represented as ISDU objects. This document is available to download from www.schmalz.com. ONFIGURATION SERVER Since revision 1.1, the IO-Link protocol has contained an automated process for transfer- ring data when a device is replaced.
SCPS CH MALZ TART OF OPERATIONS The communication LED on the IO-Link master port indicates the IO-Link communication has been successfully established. Pressing the button displays the operating mode of the ejector. A typical handling cycle is divided into three steps: pick-up, blow-off and the idle state. During the pick-up step, the switching threshold H2 is monitored to determine whether a sufficient vacuum has been established.

SCPS CH MALZ The four bits with the lowest values describe events that can only occur once per suction cycle. They are reset at the start of every suction cycle and remain stable until after suc- tioning has finished. Bit number 4, which describes excessive dynamic pressure, is initially deleted when the device is switched on and is only updated when a dynamic pressure value is detected again.
