Channel Compensation
Entering channel compensation settings ensures accurate placement of the
beads in applications where the line speed varies. Manual entry of the time
required for each gun to open, and the time required for each gun to close
provides channel compensation. Different values of compensation for each
channel can be entered.
The compensation is entered in millimeters (mm).
The pattern controller provides a process with which compensation values
can be established and entered quickly. Set the Pull−in and Drop−out
compensation to zero, produce a Normal bead test pattern at production
speed. Enter the run speed under Set speed and measure the difference
between the actual bead placement and the programmed bead start. Enter
this value as the setting for Pull−in and measure the difference between the
actual bead end and the programmed bead end. Enter the measured value
for the Drop−out setting.
