Fine Guide Point Adjustment
Fine adjustment to the guide point can only be made when the web guide is in automatic mode. These
adjustments enable small incremental changes to the guide through the operator interface to enable
operators to move the desired guiding position of the web. The fine adjustment to the guide point can be
made by pressing the left (-) or right (+) arrow icons on the operator interface while the web guiding system
is in automatic mode. Every single touch of the left or right icon will respectively decrease or increase the
guide point by 0.256 mm. This change is immediately displayed by the visual guide point indicator and the
numerical guide point indicator. Pressing the middle icon (servo-centering icon) will reset the guide point to
50% or 0 mm guide point offset.
Gross Guide Point Adjustment
The gross guide point adjustment is intended for
making a large step change in the guide point,
often after a product changeover especially with a
web width change. This adjustment can be made
by directly sliding the visual guide point indicator
track bar to the desired location; the track bar can
be moved only when the web guide is in manual
mode.
The change in the guide point needs to be
confirmed by pressing the “Accept” button that
appears whenever the track bar is moved. The
confirmation is intended to prevent any accidental
changes to the guide point. If the guide point change is not accepted within 10 seconds the change will be
disregarded and the previously accepted guide point will be restored.
NOTE:
The pressing of the Left (-) or Right (+) during fine guide point adjustment will momentarily change
the icon to green. With the release of the button the icon changes the color back to red.
WARNING:
The guide point adjustment operation results in a change in the web guide position causing
process upset. Caution must be exercised when performing this function and should be done by those who
completely understand the consequence of this change.
WARNING:
Fine guide point adjustment can be performed only when the web guiding system is in
automatic mode. Pressing the Left (-) or Right (+) icons during manual operation will perform the jog
operations.
WARNING:
Guide point adjustment should be made only if it is necessary and should be carried out by
personnel with good knowledge about the consequences of the change. The performance of the guiding
system may deteriorate if the guide point is too far away from the desired 50% setting. Some of the
changes might have no effect if the web guide is in an extreme position.
