Chapter 3: Installation
3-1 Uncrating the Equipment
Extrusion Control & Extruder Monitor units 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 extrusion control or extrusion monitor unit on the machine throat. Ensure that the
unit is mounted horizontally and is level. Check the installation to ensure that the hopper can
easily be emptied, and that the material supply hopper drop tube is not touching the weighed
colorant hopper. Support or isolate the upper material supply hopper or blending unit so that
it, or the vacuum loading equipment, is not shaking the weigh hopper so it will not effect the
accuracy of the unit.
3-3 Making Electrical Connections
Connect the 110 V power to the panel. Ensure that the circuit powering the control is clean,
and does not power other equipment that draws high current loads that will cause the voltage
to fluctuate. Excessive voltage fluctuation can cause the control to drop out. If this is not
possible, install a UPS (uninterrupted power supply) or Sola Isolation transformer.
