Operation in Automatic Mode
In Automatic Mode the web guide controller starts to guide the web to the Reference
Position and to hold this guiding point.
For edge guiding operations the Reference
Position is in the middle of the sensor
detection range (Fig. 14). For centre guiding
the Reference Position is in the middle
between the two sensor axis.
This Reference Position can be adjusted as
follows:
•
Start automatic mode with the
key.
•
The Reference Position can be adjusted in
0.1mm steps by using the and keys.
•
For left sensor operation the key causes
the web moving inside the sensor. The key causes the web moving outside the
sensor. Using right sensor operation or center guiding the setting behaves
contrariwise (refer also to Fig. 17, 18 and 19)
•
Terminate the automatic mode by using the
key again.
Caution
If web is not running, it can’t be guided properly to the Reference Position. The
steering frame moves in the limit-of-travel position and may damage the web. Start
automatic mode only when web is slowly running
Note
If the web leaves the sensor detection range, control is no longer effective. Hold the
web edge strictly inside the sensor detection band.
