Page 11: General Function Description
/ SMP CH MALZ General function description ACUUM GENERATION WORKPIECE PICK The ejector is designed for handling parts using a vacuum together with suction systems. The Venturi nozzle is activated by the "suction" signal input. On IMP versions, the "suction" signal input is evaluated for its pulse. - Page 12 / SMP 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 is activated by the "blow-off" signal input. "Suction"...

Page 15: Status Display For System Vacuum
/ SMP CH MALZ Status display for system vacuum The ejector is equipped with a status display for the system vacuum and monitoring func- GREEN tions. System states are indicated in . The status display is updated after every suction cycle that is activated over the suction signal input. During conventional suction cycles, the status display is used to display the system vacuum level based on the H1 switching point. - Page 16 / SMP CH MALZ TATUS DISPLAY OVERVIEW Suction cycle with H1 reached VD ejectors RD ejectors: [ctr=on] and no leakage or [ctr=oFF] Suction cycle with vacuum- regulation (air-saving function) [ctr=on] RD ejectors: Suction cycle with vacuum- regulation (air-saving func- tion) where the valve protec- tion function was activated [ctr=on] RD ejectors:...

Page 18: Operating And Menu Concepts
/ SMP CH MALZ PERATING AND MENU CONCEPTS The unit is operated via four buttons on the membrane keypad. Settings are made using software menus. The operating structure is divided into settings in the basic menu and con- figuration menu. Setting of the ejector in the basic menu is sufficient for standard applica- tions. -
Page 19: Manual Mode
/ SMP CH MALZ Manual 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 occur as a result. Manual mode is used for locating and eliminating leaks in the vacuum circuit. -
