COMMISSIONING
Sensing and Measurement Application
Depending on the application one or two sensors may need to be connected to the controller. Using the
functionality described in the previous section, the output of the controller should be configured
appropriately. Once the settings are configured, the user need not interact with the controller at all. The only
interaction required will be for contrast setup functionality. The screen can be used for monitoring purposes.
Please refer to the installation checklist and the sensor installation recommendation documents on the
respective sensor product page on the web site.
Web Guiding Application
A properly installed web guide requires correct threading of the web over the guide rollers and initial
positioning of the sensor based on the desired position of the web to provide optimum performance. Once
the material is threaded over the guide rollers and the sensor has been properly positioned, all the operator
has to do is to press the automatic operation icon on the operator interface. Please refer to the respective
sensor and web guide manual for proper installation of the web guiding system.
The following section describes the steps and conditions required for automatic operation with a SCU5 M
web guide controller.
Edge Guiding
1.
Power ON the system
2. Automatic/Manual operation set to “Manual” (Automatic/Manual icon pressed to red)
3. Press the Servo-Center button to center the guide rollers.
4. Thread the material over the rollers. The material wrapped over the rollers must be at a 90 degree
angle both at the entry and exit of the guide rollers.
5. Verify that the material is aligned in the desired position with respect to the upstream and
downstream position of the web. Place the web under normal operation tension.
6. Adjust sensor position on the desired edge of the web. Then manually position the sensor so that the
edge of the web is at the middle of the sensing window. This can be done by observing the web
edge position indicator on the display. When the bar is in the middle position then the web edge is
in the middle of the sensing window.
7.
If the sensor position indicator and the actual position of the sensor are different then press the “Find
Sensor” button on the operator interface so that the controller automatically finds the correct
orientation of the edge sensor. In order for this function to work the web edge needs to be in the
middle of the sensing window.
8. Tighten the sensor thumbscrews or the brake on the sensor to secure the sensor position on the
sensor rail.
9. Press the Automatic/Manual operation icon to “Automatic” (Automatic/Manual icon pressed to
green).
10. The guide will automatically adjust the position of the web material to guide it to the correct
position.
