Chapter 3: Installation
3-1 Uncrating the Equipment
Loss-In-Weight Color Feeders are shipped mounted on a skid, enclosed in a plastic wrapper,
and contained in a cardboard box.
1. Pry the crating away from the skid.
Note: Remove the nails holding the box to the skid and lift the box off
carefully; avoiding staples in the 1’ x 4’ wood supports. Cut the steel
banding.
2. Use a pry bar to remove the blocks securing the unit to the skid.
3. Lift unit from sides. Use a pry bar if necessary to carefully remove the
skid from the unit.
4. Lower slowly.
3-2 Rigging and Placing the Unit
Install the feeder on the machine throat. Ensure that the unit is mounted horizontally and not
angled. Check the installation to ensure that the feeder can easily be emptied, and that the
extruder supply hopper is not touching the weighed colorant hopper. Support the feeder so
that it is not subject to processing machine vibrations, etc. that can affect the accuracy of the
unit.
3-3 Making Electrical Connections
Connect the 110V power to the panel. Ensure that the circuit powering the control is clean,
and does not also power other equipment that draws high current loads. The control circuit is
provided with a high quality isolated power supply; however, it should not be subject to
voltage fluctuations other than normal conditions.
Description and Objectives
This section is designed to give the operator an overview of the electrical system that controls
the Feeder system. Since the control panel is a self-contained pluggable item, seldom will a
maintenance person be required to enter the control panel. For purposes of understanding the
system, it is advisable that the maintenance personnel be familiar with not only the internal
workings of the control panel, but also with the input and output signals to the unit.
This section includes the following:
• Internal components of the control panel
• Input signal to the control panel
• Output signals from the control panel
