SCPSb C HMA LZ NSTALLATION AND OPERATION For safe installation and trouble-free operation, please observe and comply with the follow- ing 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.
SCPSb C HMA LZ 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 using the “suction” pilot valve. In the NO version, the venturi nozzle is deactivated when voltage is applied.

SCPSb C HMA LZ ESCRIPTION OF UNCTIONS ENERAL FUNCTIONS 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 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. Schmalz connection lines may be used to connect the ejector directly to the controller, e.g. Art.-no. 21.04.06.00086, 3m ...
