Using the LineMaster Yield Screen
Yield Control offers to the operator, the ability to control Co-Extrusion Lines consisting of 1 to 7
extruders while intelligently controlling the downstream Take-Off equipment.
Yield Screen - Startup Process:
In the G2 Client, select from the menu above, Control then Yield to open the Yield Screen. In the
Yield Screen, select your line from the dropdown menu in the upper-right. This will display your
line and all blenders within the line.
Explanation of the Yield Screen
The Yield Screen - On the left side of the screen are information
tables, one for each extruder's WSB/LIW controller. Depending on
the number WSB/LIW controllers you are using, 1 to 7 tables will
be displayed. Verify that all blenders are ONLINE. All blender
Ids and their corresponding information will be loaded into the
appropriate fields. If any blender is listed as OFFLINE meaning
G2 cannot communicate with that blender for any reason, the
corresponding table of information for that blender will be grayed
out. Before proceeding with Yield Control, you will must bring that
blender ONLINE.
Each table consists of the blender's unique ID number, the
Throughput %, the current voltage, the current throughput, and an
alarm indicator.
Clicking on the WSB/LIW ID field will bring up a screen where you
can further examine the line. This screen will display an more
detailed examination of each blenders settings and outputs.
At the right are your take-off controls. Displayed are: two columns
of information, Target and Actual. The fields within the columns
are Voltage (Actual voltage only), Line Speed, and Yield. Line
Speed is displayed meters per minute (m/min) or in feet per
minute (ft/min). Yield is displayed in grams per meter (grs/m), or
grams per foot (grs/ft). Measurement units are set in the Setup
Screen when choosing your Weight Units.
All lines will visually merge where your Total Throughput will be
displayed.
