SSV 05 2. Installation instructions » These installation instructions are intended for persons with skills in electrical and mechanical areas due to their training, experience and received instructions. Personnel using these installation instructions must be instructed in the regulations for the prevention of accidents, the operating conditions and safety regulations and their implementation. Ensure in each case that the personnel are informed.
SSV 05 2.1.
SSV 05 2.2. Installing the conveyor hopper The single conveyor unit is not sensitive to shocks and can be installed directly on the processing machine. Make sure that all connections are tight so that the conveying performance is not impaired. The conveyor hopper is equipped with a universal flange. Depending on the position, drill the holes for fastening the conveyor hopper to the processing machine. Mount the conveyor hopper on the processing machine.
SSV 05 2.3. Installing the control and maintenance unit Install the control and maintenance unit at a freely accessible site. Observe the length of the connection cable and of the supplied hoses to the injector tube. 0 During installation, observe the length of the supply lines.
SSV 05 2.4. Connecting the compressed-air supply Check compressed-air piping for correct installation and assembly. Check fittings, length and quality of the hose connections for agreement with requirements. Check all compressed-air lines for leakages. You need a compressed-air supply with 5 - 6 bar (72.52-87.02 PSI) system overpressure. The air should be free from oil and water, if possible.
SSV 05 2.5. Electrical connection » Observe the regulations of the local electricity board. The operating voltage is 230 V, AC, PE, 50/60 Hz. Special voltages available on request. The connected load is approx. 15 W. The connection takes place by means of a mains connector. A separate protection of the socket is not necessary. Connect the plug of the probe cable to the control unit. SM4-600 Plug the mains connector into a corresponding socket.
SSV 05 3. Functional description » This functional description is intended for the operating personnel of the equipment. General knowledge of operating conveyor units is a prerequisite. Ensure in each case that the operating personnel are sufficiently informed. SM4-600 F The single conveyor unit SSV 05 is designed for conveying free flowing pellettized plastic materials directly on the injection molding machine.
SSV 05 3.1. Method of functioning The single conveyor unit works according to the venturi principle. An external compressed-air supply is needed. A venturi meter (A) is integrated in the injector tube. The venturi meter aspirates the material in the lower part of the tube (C) and then conveys the material into the conveyor hopper by means of compressed air in the upper part (B). In the hopper loader, the material is separated from the air.
SSV 05 4. Set-up » This chapter is intended for the operating personnel of the equipment. General knowledge of operating conveyor units is prerequisite. The functional description must have been read and understood. SM4-600 Ensure in each case that the operating personnel are sufficiently informed.
SSV 05 4.1. Preparations Check whether the injector tube is inserted in the material to be conveyed. Switch on the compressed-air supply. Switch on the conveyor unit at the control and maintenance unit. The conveyor unit should now convey until the conveyor hopper is filled up to the level probe. 4.2. Basic setting of the filling level in the conveyor hopper The filling level in the conveyor hopper is mainly determined by the level probe.
SSV 05 4.2.1. Fine adjustment of the filling level in the conveyor hopper & Before the fine adjustment, carry through a basic adjustment. During operation, carefully turn the adjustment screw (A) of the level probe by means of a screwdriver until the desired filling level is reached. A & Clockwise rotation makes the filling level fall. Counterclockwise rotation makes the filling level rise.
SSV 05 5. Maintenance » This chapter is intended for persons with skills in electrical and mechanical areas due to their training, experience and received instructions. Personnel using the instructions in this chapter must be instructed of the regulations for the prevention of accidents, the operating conditions and safety regulations and their implementation. Ensure in each case that the personnel are informed accordingly. For maintenance work taking place at heights of over approx.
SSV 05 L Disconnect the equipment from mains supply before starting maintenance procedures to ensure that it cannot be switched on unintentionally. Depressurize all compressed air piping of the equipment before starting maintenance work. F Please observe the maintenance intervals. Before starting maintenance work, clean the equipment of oil, fuel or lubricants.
SSV 05 5.1. Maintenance intervals daily: Check the setting of the pressure reducer. Empty the water separator. Check the danger signs on the unit for legibility and completeness. monthly: Clean the filter and sieve (depending on accumulation of dust!). Blow out the filter from the inside out by means of compressed air. Check the unit plugs for proper functioning. every six months: Check all electrical and mechanical connections for proper fit.
SSV 05 5.2. Cleaning/replacing the filter cartridge » Switch off the unit. Disconnect the mains plug. Disassembly Remove the filter cartridge (A). Blow out the filter cartridge (A) from the inside out by means of compressed air or replace the filter. Open the tension ring (B). Remove the nozzle (C) and the sieve (D). Check the sieve (D) for material residue. Clean the sieve (D) by means of compressed-air. Replace the sieve and sealing ring in case of damage.
SSV 05 Assembly Assemble the sieve and the sealing ring. Mount the nozzle Mount the tension ring Assemble the filter cartridge. & Order number filter cartridge: ID 98171 Sieve: Sealing ring: ID 18491 ID 31160 5.3.
