2-2 Installing the Material Receiver The self contained material loader can be installed directly on the processing machine. Make sure that all connections are tight so that the conveying performance is not impaired. The material receiver is equipped with a mounting flange. Depending on the position, drill the holes for fastening the conveyor hopper to the processing machine. One of 2 standard bolt patters may be used, sight glass or bin mounted.(as shown in fig. 2.4) Mount the mat

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 hos

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.

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. If included at the time of original purchase, all of thes

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. Once the material level drops (typically due to process consuming material) and the SVL sensor no longer “sees” ma
