Additive Feeders Chapter 2: Functional Description 12 of 55
Motor Assembly
• Quick release swing-away motor mount speeds auger/motor changes and cleanout
• Permanently lubricated
• Replaceable motor brushes
Electrical Features
Motor Assembly
• Continuous service fractional horsepower DC motor.
• Hall Effect sensor transmits RPM to microprocessor control
• 115/1/60 supply voltage
Controller Features
• Closed-loop control constantly monitors feedback from the auger motor RPM sensor
for high accuracy and repeatability. Feed rates remain stable during main power
supply voltage fluctuations.
• Remote control mounting capability permits mounting the control panel up to 9 feet
from the feeder.
• Field-programmable display permits viewing in rpm, pounds per hour, kilos per hour,
etc., as well as high/low limits.
• Automatic and manual/calibration operation modes.
2-4 Options
Special Voltage
• 230/1/60 VAC
Timer/Counter Control
• Designed for use with cycled processes like injection molding
• Cycle timer can be set to limit the additive feeder cycle to avoid feeding straight color
if a resin supply problem occurs in conjunction with a processing machine control
relay failure.
• Batch counter provides inventory management information
• Calibration feature allows precise, repeatable sampling during setup
Timer/Elapsed Timer Control
• Designed for use with continuous processes like extrusion
• Elapsed timer provides inventory management information
• Calibration feature allows precise, repeatable sampling during setup
