orientation, then web position from the sensor connected to Sensor 1 port will be displayed on the left and
the right half indicating the web position from the sensor connected to Sensor 2 port.
When in contrast mode the white bar graph may turn into gray segments representing the various contrasts
on the web and the contrast position indicated by a vertical green line.
Sensor Orientation Indicator
The four sensor orientation indicators provide quick feedback on the orientation of each sensor. Each
sensor can be oriented to pick the left edge, right edge or both edges. The two indicators on the left
correspond to the left orientation for Sensor 1 and Sensor 2 while the two on the right correspond to
the right orientation for the two sensors. When a particular orientation is chosen for a particular sensor the
corresponding indicator will turn green; if not the indicator would appear gray.
Find Edge Button
The find edge button is used by the operator to set the job appropriately based on the desired edge
that is used for sensing and guiding purposes. The find edge button serves dual purpose based on the
sensor configuration in the power user screen.
1.
Automatically find the sensor orientation: When one or both sensors are set to detect the orientation
automatically, pressing the find edge button will detect the correct orientation for the sensor(s) with
respect to the web in the sensor’s field of view.
2. Enable and disable the sensors: When both sensors are set a predefined orientation pressing the
find sensor button will successively enable and disable the connected sensors electronically
Automatically find the sensor orientation
The sensor orientation with respect to the web can be automatically detected in this mode when the find
edge button is pressed. This allows for quick job changes when the sensor is repositioned within the
machine. This is especially useful while using a single sensor that is repositioned to pick either the left edge,
right edge or both edges.
This functionality is used whenever the sensor orientation with respect to the web is changed. For example,
if the sensor is moved from the operator side to the drive side for a job, then as soon as the repositioning
happens the find edge button can be pressed to switch the sensor mode from left edge to right edge (or vice
versa). If both edges of the web are seen within the field of view of the sensor then the sensor orientation
would change to center mode.
Enable and disable the sensors
When the orientation of the sensors are fixed then the find edge button allows the user to quickly enable and
disable the sensors for easy job change. For example, when two sensors are connected to the controller and
are configured for a respective sensor orientation, then successive press of the find edge button would have
the following effect:
●
Enable sensor 1 and disable sensor 2
●
Enable sensor 2 and disable sensor 1
●
Enable both sensor 1 and sensor 2
●
Disable both sensor 1 and sensor 2
