2-3 Installing the Control Assembly Install the control assembly at a freely accessible site. Check the length of the connection cable and the length of the supplied hoses to the venturi assemblies. During installation of equipment, check the length of the air supply lines. In some cases, longer air supply lines may be required. Figure 2.
2-4 Connecting the Compressed Air Supply Before connecting the compressed air supply, check the following: Check compressed air piping for correct installation and assembly. Check the fittings, length and quality of the hose connections for agreement with requirements. Check all compressed air lines for leakages. Supply clean, dry (non-lubricated) compressed air with 70-90 psi (5-6 bar) system pressure. The air should be free of oil and water. 1. Find the compressed air hose, which has been supplied. 2.
2-5 Connecting Material Lines Typical SVL Loader installations use flex hose to connect the loader to the venturi. Caution! The material hose should be as straight as possible. Avoid loops and S-curves in flexible hose. This can hurt conveying performance. 1. Attach flex hose over the inlet stub of the loader. Secure the hose with the provided hose clamp. The hose should fit over the inlet stub at least 1 inch. Position the hose clamp at least ¼ inch from the end of the inlet. 2.
SVL-C (Two inlet) Installation Any SVL loader may be equipped for “ratio” or proportioning loading so that two materials (usually virgin and regrind) may be loaded simultaneously. The equipment for this function consists of a “Y” tube and coupler that is installed on the inlet stub of the loader, two controls (one for each component,) a pick-up device (feed tube), a second venturi and both compressed air lines and material hoses.
2-6 Electrical Connection The operating voltage is 115 or 230 VAC, AC, PE, 50/60 Hz. Special voltages available by request. The connected load is approximately 2 Watts. The connection is made using a main connector. A separate protection of the socket is not necessary. Connect the plug of the sensor cable to the control unit. Plug the main connector into a corresponding socket. Make sure all equipment is properly grounded. WARNING! Check with the local electricity board for regulations.
Chapter 3: Functional Description 3-1 Operational Summary Once the control switch(s) is turned on, the SVL loader uses a solid state sensor to determine if material is needed at the material destination (hopper, bin, sight glass, etc.) If the sensor “sees” material, the loader will remain in an “at rest” mode with its solenoid de-energized and no compressed air flowing.
3-2 Method of Functioning The self-contained venturi loader works according to the Venturi Principle. An external compressed air supply is needed to provide the source of compressed air. A venturi device (A) is integrated in the venturi assembly. The venturi creates a vacuum in the lower part of the tube (C) and then conveys the material into the conveyor hopper using pressurized air in the upper part (B). In the hopper loader, the material is separated from the air.
3-3 Control Assembly A. The unit is switched ON and OFF at the control. B. At the regulator, the operating pressure is adjusted. A filter/separator is integrated into the control. C. Regularly inspect the compressed air filter to make sure that it is clean and functioning properly. Clean or replace this filter as needed. For information, see Section 5: Maintenance. Figure 3.
Chapter 4: Setup 4-1 Preparations Check to see if the venturi assembly is inserted in the material to be conveyed. Verify compressed air connections are properly installed. Switch the compressed air supply ON at the compressed air source. Check pressure of air supply at the control assembly. Make sure unit and control are properly grounded. Switch the conveyor unit electrical switch ON at the control and maintenance unit.
adjusted first for optimum flow, as described above. Since regrind material is typically more difficult to load than virgin material, it will take more compressed air (a higher setting on the regulator) than virgin material. Once regrind is adjusted, then the virgin material flow should be adjusted. Notice the flow of material through the flex hose as both are loaded.
4-4 Basic Setting of the Filling Level in the Conveyor Hopper The filling level in the conveyor hopper is mainly determined by the level sensor. Figure 4.1: Conveyor Hopper Function and features: • Capacitive level switch for monitoring and dry bulk material, preferably plastic granulates. • Automatic adjustment to the medium to be detected by means of programming pushbutton.
Programming: Overview of the modes and their basic functions: • Operating mode: Normal operating mode. In this mode all normal sensor functions are active. • Adjustment mode: Setting of the switching threshold by empty and full adjustment. • Locking mode: Locking and unlocking of the unit possible to avoid tampering. Empty adjustment The unit must be adjusted after installation in the empty tank (empty adjustment).
Full adjustment After empty adjustment the full state is to be achieved, if possible, so that the unit switches. The full adjustment can be repeated as often as you like. The stored value for the empty state is not overwritten by the full adjustment. After a new empty adjustment both values are automatically set again, the values last defined are overwritten.
Unlocking When the programming pushbutton is released the unit is unlocked and all programming functions are active again. Error messages If empty or full adjustment cannot be made, the red LED flashes quickly at about 8Hz after the adjustment attempt (adjustment error). To delete this error message press the programming pushbutton once or power off and then power on again. The measured values successfully read so far remain unchanged.
Set-up / Operation: Check the safe functioning of the unit. To do so, bring about a sensor response by taking suitable measures.
Chapter 5: Maintenance Preparations Please observe the maintenance intervals. Before starting maintenance work, clean the equipment of oil, fuel or lubricants. Ensure that materials and incidentals required for operation as well as spare parts are disposed of properly and in an environmentally sound manner. Use only original manufacturer spare parts. Keep record of all maintenance and repair procedures.
5-2 Cleaning the Conveying Filter WARNING! Disconnect power air sources. Always disconnect the main power source and compressed air source before removing the filter. This prevents the loader from starting during servicing, which could cause injury from flying debris. Caution! Wear eye protection. We recommend that you use vacuum air for cleaning filters and other parts of this equipment.
4. Install/reinstall the filter. Firmly press down on the filter to make sure a good seal is provided around the entire perimeter of the filter module. The filter should fit evenly on the top of the loader body. Figure 5.1: SVL-A 5-3 Figure 5.2: SVL-B Cleaning the Compressed Air Filter The compressed air supply to the loader is provided with a moisture trap to prevent troublesome moisture, contained in the air, from touching your material.
Disassembly 1. Remove the filter cartridge (A). 2. Blow out the filter cartridge (A) from the inside out using compressed air or replace the filter. 3. Open the toggle-type fastener (SVL-B, SVL-C models) (C) and fold the hopper lid upward. 4. Check the screen (B) within the lid for material residue. 5. Clean the screen (B) using compressed air. Assembly 1. Clean the hopper loader using a vacuum cleaner. 2. Replace the cover gasket/screens (SVL-B, SVL-C.) 3. Close the hopper lid (SVL-B, SVL-C.) 4.
