XC-2 - Yield Control X or Yield Control T
XC-2 offers the ability to maintain a product’s weight per
length (lb/ft or gm/M) by monitoring the process throughput
against the line speed. An XCE Digital Encoder mounted on a
take-off device monitors the line speed. Control is
accomplished by adjusting either the extruder speed with a
XCD-X Drive Speed Control Module by referencing the
manually controlled line speed or controlling the take-off
speed with a XCD-T Line Speed Control Module from a
manually controlled extruder.
XC-2 has two options for control of grams per length.
YLDX – The Take-off drive speed is controlled manually.
When in lock mode, LineMaster Extruder Speed Control will
adjust the extruder automatically to follow the line speed to
maintain yield.
YLDT – The Extruder drive speed is controlled manually.
When in lock mode, LineMaster Take-off Speed Control will
adjust the take-off automatically to follow the Extruder speed
to maintain yield.

XC-2 Startup
Before startup, make sure material is available at the fill valve of the Loss-in-weight hopper.
YLDX Mode
1. With the LineMaster Extruder Speed Control in the MANUAL
position, turn main power of LineMaster (XCC) Controller ON
Display will read:
0.0 g/l
YLDX UNLOCKED
2. At the LineMaster Extruder Speed Control begin increasing the
voltage by rotating the ADJUST pot clockwise. Rotate ADJUST
pot until desired RPM (voltage) is attained. Material begins to flow
through the Loss-in-weight hopper and into the extruder. Once the
take-off is running and rotating the
Encoder , producing feedback
to the LineMaster (XCC) Controller , an actual rate of grams per
length (g/l) is displayed.
3. When the desired rate of flow is attained, the LineMaster
Extruder Speed Control can be put into the LOCK position to
maintain the current rate of grams per length (g/l). In LOCK
position, automatic adjustments to the (0-10v) extruder voltage are
made by the LineMaster (XCC) Controller to maintain the locked
rate of grams per length (g/l).
