Chapter 2: Safety 2-1 How to Use This Manual Use this manual as a guide and reference for installing, operating, and maintaining your granulator. The purpose is to assist you in applying efficient, proven techniques that enhance equipment productivity. This manual covers only light corrective maintenance. No other maintenance should be undertaken without first contacting a service engineer. The Functional Description section outlines models covered, standard features, and safety features.
2-2 General Safety Information These Remote Proportioning Valves (or RPVs) are designed to provide safe and reliable operation when installed and operated within design specifications, following national and local safety codes. To avoid possible personnel injury or equipment damage when installing, operating, or maintaining this equipment, always use good judgment and follow these safe practices: ; Follow all SAFETY CODES. ; Wear SAFETY GLASSES and WORK GLOVES.
2-3 Warnings and Precautions The installation, operation and maintenance of this equipment is to be conducted in accordance with all applicable work and safety codes for the location where it is used. This may include, but is not limited to, OSHA, NEC, CSA, SPI, and any other local, national, and international regulations.
Chapter 3: Functional Description 3-1 Models Covered in This Manual This manual offers a general reference for the installation and operation of the Remote Proportioning Valve (RPV) with control configurations A, B, C, and D. Material inlets and outlet sizes range from 1.5” to 2.5”. 3-2 General Description The Remote Proportioning Valve is an efficient and economical means to proportion two different free-flowing granulated materials in a material conveying system.
3-4 Typical Features and Components The RPV is available with a variety of control choices designed to suit your particular operation. RPV-A The A model Remote Proportioning Valve is designed exclusively for use with the Autoload Hopper Loader. RPV- B and D The B and D model RPV’s are designed for use with central vacuum systems. These models will convert any existing vacuum hopper into a proportioning unit, regardless of manufacturer. The RPV – B uses 110 VAC supply voltage.
Chapter 4: Installation 4-1 Mounting the RPV The RPV can be mounted to a machine, on the floor, or on a wall. The optional floor stand provides installation location flexibility. The RPV can be used with more than one machine by switching hoses and positioning the floor mounted RPV in a convenient place. Wall Mount Installation This type of installation uses the optional wall mounting bracket to mount the Remote Proportioning Valve to a convenient wall, pipe, or other structural member.

Floor-Mount Installation Use the following procedure to install the RPV using the floor stand: (See Figure 2 for more information.) 1. Assemble the stand by inserting the standard into the floor plate and tightening the set screw. 2. Complete the assembly by following steps 3 throuh 6 on page 12. 3. Position the floor stand so the clean-out and inspection hatches are accessible and the material hoses do not interfere with workspace or create a tripping hazard.
Machine-Mount Installation In this installation, the RPV is mounted directly to the material inlet of the hopper loader or vacuum hopper it will serve. The hopper loader or vacuum hopper inlet tube provides the support for the RPV. WARNING! Make sure that the hopper loader or vacuum hopper inlet can support the weight of the RPV (approximately 10 lbs.) and any unsupported material supply hose. A properly-installed hopper loader or vacuum hopper can support 250 lbs. of downward force.
4-2 Installing the RPV Controls DANGER! Disconnect and lock out power before working on equipment. Do not reconnect electric power until the installation is complete, the work has been checked, and all tools are removed, and all safety devices are activated. All electrical work must conform to all codes in effect at the installation site. Installing the RPV-A Autoload Knob Box Control If your RPV has the RPV-A control package, use the following procedure to install it: 1.

Installing the RPV-B and RPV-D Standalone for Central Vacuum Systems This control configuration is used to convert a central system vacuum hopper into a proportioning vacuum hopper. The stand-alone control can be used in systems with 24 VDC or 110 VAC T-valve solenoids. The RPV-B requires an external 110/60/1 VAC power supply. The RPV-D requires a 220/5060/1 power supply and the proper plug and power cable (supplied by customer).

Installing the RPV-C 9953 and 9963 Hopper Loader Control Use this control configuration to convert an existing 9953 or 9963 hopper loader into a proportioning hopper loader. The circuit board within these hopper loaders contains the circuitry necessary to control a Remote Proportioning Valve. Wire the solenoids in the Remote Proportioning Valve as shown in Figure 7. Use #18AWG wire for the solenoid connections. If your RPV has the RPV-C control package, use the following procedure to install it: 1.
Chapter 5: Operation The RPV can be controlled by one of three different controls. See Chapter 4: Installation for installation instructions. • Knob box — Used with Autoloader hopper loaders. This control is supplied with Model RPV-A. • Stand-Alone control — Used with central vacuum system vacuum hoppers. This control is supplied with models RPV-B and RPV-D. • Hopper loader control — Used with 9953 and 9963 hopper loaders.
5-2 Standalone Control Operation The Stand-Alone Control is provided with RPV models B and D and is used with central vacuum system operated vacuum hoppers. The Stand Alone control box has these features: Power Switch The power switch on the stand-alone box must be in the ON position during operation. If the power switch is turned off during operation, the RPV will stop conveying and the central vacuum system will sense a high vacuum condition and initiate a blowback cycle.
5-3 Hopper Loader Conversion Operation The RPV-C converts 9953 and 9963 hopper loaders into proportioning hopper loaders using the controls included with existing AEC models. If you are familiar with the operation of 9955 and 9965 proportioning hopper loaders, the RPV-C is operated in the same manner. Adjust the potentiometers in the control enclosure as you would with a 9955 or 9965.
5-4 Weight Test for Accurate Proportioning To get an accurate proportion of regrind and virgin materials, run the test described below to determine the conveying rate of your particular installation using your materials. The test will determine the ratio settings needed to deliver the desired mix. 1. Determine the total throughput of the machine. This is equal to the amount (pounds) of material your processing machine uses in an hour. 2.
Chapter 6: Troubleshooting 6-1 Introduction The utmost in safety precautions should be observed at all times when working on or around the machine and the electrical components. All normal trouble-shooting must be accomplished with the power off, line fuses removed, and with the machine tagged as out of service. The use of good quality test equipment cannot be over-emphasized when troubleshooting is indicated.
Problem Possible cause Solution Control is on and working, but valve does not work. Faulty compressed air connection to valve. Repair connection/replace connector. Must have minimum 60 psi. Inadequate incoming vacuum signal and voltage. Locate problem, repair/ replace as needed. Loose connection wiring in control box. Repair/replace as needed. Improper shroud solenoid voltage compared to control output voltage. Compare voltage rating of solenoids in shroud to output voltage of controls.
