Additive Feeders Chapter 7: Appendix 39 of 50
7-2 Optional Components
The following is a list of options which your Additive Feeder may have been equipped with:
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
Dual Setpoint Control
• Used with multiple feeder installations where one feeder is feeding colored regrind and
another is feeding straight color. A low level monitor senses when the supply of
colored regrind is depleted and alters the feed rate of the pure color feeder to maintain
precise color quality control automatically.
Extruder Following Feature
• Pulse adder board increases range of microprocessor control to 500,000 pulses per
minute to accommodate a wide variety of TTL-type extruder rpm sensor signals.
• Feature is enabled with a DIP switch adjustment.
Expanded Supply Hopper
• 2.0 cubic foot capacity
Supply Hopper Covers
• Hopper mounting cutout for vacuum receivers
• Hopper loader mounting cutout for hopper loaders
Additional Auger Assemblies
• Switch augers for changing process throughputs
Mounting Adapters
• Special main throat and flanges can eliminate transitions and accommodate different
machine hoppers
