Alignment of the Sensors
•
Align sensor axis to the web edge: Loosen
the fixing nut on the bracket and adjust the
sensor. Fix the sensor in the new position.
The sensor will be positioned properly if
the web edge goes through the sensor axis
(center of active window; refer to fig. 17).
Automatic Operation
•
Start automatic mode with special function
Automatic
(fig. 16) or digital input. The
control LED
Auto
lights up. Reference
position is taken from the middle of the
sensor detection band (fig. 18). Using
center guide, reference position is in the
middle between the 2 sensor axis. The
controller starts to guide the web to
reference position and to hold this guide
point.
•
The reference position can be adjusted
during automatic operation with the special
function
Reference
(fig. 16) or using digital
inputs (step width 0.1mm). With the

the web moves out of the sensor; with the
↓
key, the web moves in. Using center guide,
this description applies to the right sensor.
•
Quit automatic mode with calling the
special function

again (fig. 16).
The control LED

goes off.
Note
If the web leaves the sensor detection band, control is no longer effective. Hold the web
edge strictly inside the sensor detection band.
Note
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!
