Chapter 1: Safety 1-1 How to Use This Manual Use this manual as a guide and reference for installing, operating, and maintaining your additive feeder. 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.
1-2 Warnings and Precautions Our equipment is designed to provide safe and reliable operation when installed and operated within design specifications, following national and local safety codes. This may include, but is not limited to OSHA, NEC, CSA, SPI, and any other local, national and international regulations.
1-3 Responsibility These machines are constructed for maximum operator safety when used under standard operating conditions and when recommended instructions are followed in the maintenance and operation of the machine. All personnel engaged in the use of the machine should become familiar with its operation as described in this manual. Proper operation of the machine promotes safety for the operator and all workers in its vicinity.
Operator Responsibility The operator’s responsibility does not end with efficient production. The operator usually has the most daily contact with the equipment and intimately knows its capabilities and limitations. Plant and personnel safety is sometimes forgotten in the desire to meet incentive rates, or through a casual attitude toward machinery formed over a period of months or years. Your employer probably has established a set of safety rules in your workplace.
• Clean the feeder and surrounding area DAILY, and inspect the machine for loose, missing or broken parts. • Shut off power to the feeder when it is not in use. Turn the switch to the OFF position, or unplug it from the power source.

Calibration Procedure This procedure allows the operator to precisely adjust additive feed rates. Caution! Never put hands or tools in or near the auger assembly when power is connected. Do not wear gloves or loose clothing during calibration. The auger is exposed when the calibration or cleanout hatches are open. Equipment Needed: • Scale • Sample container • Timer- stopwatch, watch/clock w/second hand Procedure 1. Close cleanout and calibration hatches. 2. Fill the additive supply hopper. 3.
Examples: This example shows how to extrapolate a desired feed rate of 3 lbs./hr., based on the feed rates of 3 trial rpm settings. Observed Feed Rates Sample 1 = 2 pounds per hour @ 20 rpm Sample 2 = 4 pounds per hour @ 40 rpm Sample 3 = 6 pounds per hour @ 60 rpm In this example, a feed rate of 3 lbs./hr. would be about 30 rpm.
3-5 Initial Start-up Pre-Startup Checks ; Are all the electrical connections correct, secure and to code? ; Is the auger insert locked in place? ; Are the motor and auger properly coupled and the motor mount locked in place? ; Are the cleanout and calibration hatches shut and secured? ; Are all tools, hardware, etc.
Chapter 4: Operation 4-1 Start-up 1. Turn the power switch ON. 2. Set the desired feed rate on the RPM display using the up or down arrows. 3. Flip the motor switch to AUTO. If the additive feeder is installed correctly, it should begin operation at the desired RPM when the processing machine screw is in operation. 4-2 Controller Description and Operation Identifying Control Panel Indicator Lights and Switches on the Controller Switches Power Switch. This switch turns the control ON and OFF.
Procedure 1. Time the duration of feeder operation during a typical Injection molding machine shot cycle. 2. Set the timer to a slightly longer value. 3. Start the additive feeder by flipping the motor switch to the AUTO position. 4. If the timer times out because of a process flow problem, the feeder will automatically stop. 5. Reset the power switch.
4-3 Injection Molding Applications Discussed in this portion of the manual are the finer points of the additive feeder operation, programming the control, and installation notes and examples.

feeder. If you do not have these drawings contact service to have them forwarded to you. Injection Mode Application Notes The additive feeder controller has the ability to display feed rates in units other than the factory set auger RPM display. With proper programming, the feeder can display pounds/hour, grams/minute, etc. Programming for units other than auger RPM REQUIRES that the system be calibrated to determine exactly how much material is delivered at specific RPMs.
4-4 Extrusion Applications Discussed in this portion of the manual are the finer points of the additive feeder operation, programming the control, and installation notes and examples. If you are unfamiliar with this product or have never performed this type of installation, please read this section of the manual fully before installing the equipment.
Extruder Tracking Installation and Setup The additive feeder control is supplied with standard factory defaults. Control programming is required to suit the requirements of your process (See page 24, Field Control Programming). Connect the TTL signal acquired from the extruder control or from a sensor you have installed to the terminal strip as shown in the electrical schematics provided with your unit’s installation packet. 1. Install the feeder as described in Chapter 3. 2.
Field Control Programming Although the drive’s user interface is very versatile, it is also simple to setup and operate. With just a few button presses, it allows the user to configure a number of adjustable parameters. The LED display has three basic operating modes: Running Mode, ParameterSelection Mode, and Value Mode. Each of the three modes have specific visual indicators that allow the user to immediately determine the current state or mode of the user interface.
Resetting the Unit to Un-Programmed State The factory-default settings can be easily restored using either of two methods. Both methods require the Program Enable jumper to be in the “On” position. The first is to apply power to the unit with both the Enter and Down buttons pressed for 3 seconds. The second is to change the value of parameter 95 to 5. JP1 (Program Enable Jumper) The JP1 jumper is located under the dust cover on the back end of the upper board.
14. Use the Up and Down Arrow buttons to go to the next parameter to be modified. Repeat as required for any remaining parameters. 15. When all program modifications are completed, use the Up and Down Arrow buttons to go to parameter “0” then press the Enter button to return to run mode. 16. Remove the power source from the controller. Following the procedures in your facility, lockout or tagout the power source. 17. Remove the dust cover from the control enclosure. 18.
Example 1: An extruder rotating at 30 RPM and providing 8 pulses per revolution generates 240 pulses per minute will provide excellent results. Example 2: An extruder rotating at 15 RPM and providing 1 pulse per revolution generates 15 pulses per minute and will provide poor results. Maximum Input Pulse Rate As programmed, the drive is capable of accurately following an extruder’s rate signal of up to 50,000 pulses per minute.
Chapter 5: 5-1 Program Parameter Descriptions Defining Program Parameters Parameter 0 – Exit to Running Mode When parameter 0 is selected in Parameter-Selection Mode, the unit will return to Running Mode and display the running value. This should be selected once changes to parameters are completed. Parameter 10 – Operating Mode This parameter defines the operating mode for the entire unit. There are two basic modes of operation, master and follower.
Mode 2: Non-linear, Accelerating Rate In non-linear mode, pressing and holding the Up or Down buttons will cause the display to continuously change value in the requested direction until either the Display Minimum or Display Maximum is reached. The displayed value will initially scroll at a slow rate and increase in speed until the maximum scroll rate is achieved. The initial scroll rate is specified using parameter 15.
Parameter 19 – Power-up Value When Power-up Mode is set to 2, this parameter will designate the default display value at power-up in display units. Parameter 20 – Display Minimum This parameter defines the lower end of the display range. This is the value which limits how low the user is able to scroll the displayed value in Running Mode. In Rate and Time modes, this value is set in display units. In Follower Mode, this is set in percentage of the master rate.
Parameter 31 – Signal Input 1 (S1) Reference RPM This is the reference RPM at which the Display Reference value should be displayed. In Rate and Time Modes, this value represents the RPM of the encoder to which the Display Reference corresponds. In Follower Modes, this value is not used. Parameter 32 – Signal Input 1 (S1) Pulses per Revolution This is the number of pulses per revolution for the signal input 1 (S1). The drive supports pickups and encoders from 1 to 2048 pulses per revolution.
Parameter 36 – Signal Input 2 (S2) Setpoint When the S2 configuration, parameter 35, is set to one of the jog modes, this parameter defines the jog setpoint in display units. If the drive operating mode is set to Follower Mode, then this parameter is set in RPM units. This allows a follower control to be jogged when the master is stopped. Parameter 37 – Signal Input 2 (S2) Pulses per Revolution This is the number of pulses per revolution for the signal input 2 (S2).

Auger Assembly Changeover Our additive feeder auger assemblies may be removed and installed without tools. All auger sizes are interchangeable.
Motor Brush Replacement The two (2) motor brushes should be replaced when they are worn down to less than 1 inch in length. Replacement brushes are “pre-worn” by the manufacturer and require no break-in period. Caution! Disconnect power to the Additive Feeder before changing the motor brushes. 1. Remove a brush cap screw near the back of the motor. Caution! The motor brushes are spring loaded. Use care to avoid eye injury when removing the cap screw. Wear safety glasses when performing this procedure.
Chapter 7: Troubleshooting 7-1 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 troubleshooting 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 Field contact jumper (J1) has not been removed. AUTO MODE. Motor will not stop. Motor runs only at maximum speed. Motor speed not constant. Additive is contaminated by color from previous run. Field contact to the processing machine has failed. Motor switch has failed. Field contact to process machine missing or loose. Control relay has failed. Motor control has failed. Optional timer set incorrectly. Optional timer has failed. Signal from motor speed sensor missing.
AC line supplying power has too much noise. Review routing of power wires in machine to minimize electrical noise. Look for other devices which share the same circuit and may be producing unacceptable levels of line noise. In some applications, such as welding equipment, a careful regiment of applying an AC line filter, re-routing wires, dividing circuits, using shielded cable, and properly grounding devices will usually solve the problem. AC line supplying power to unit has an abnormally high frequency.
