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

Options marked with “*” indicate options that can be factory installed or retrofitted in the field.

Special Voltage

230/1/50 VAC

Timer/Counter Control

Designed for use with cycled processes like injection molding

Cycle timer can be set to limit 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
