3.5 Analog outputs
3.5.1 DST-1 Analog output 1 and 2
The outputs are designed to provide real-time control signal to a
web guide system. They provide proportional response to detected
web offset.
Both of the outputs are formed by open-drain transistor pins and
the Common Return signal.
Each output requires an external load resistance value of 100 Ohms,
connected between the output and return. (This applies only if a
voltage output is needed in a stand-alone configuration.)
Outputs can be independently configured to deliver range of 0 to10,
0 to 20 or 4 to 20 mA over the input load.
Outputs can be independently configured for an inverted polarity.
For example, 0 to10 can be switched to 10 to 0 output.
INSTALLATION
The default range setting for the Output 1 is 0 to 10 mA.
The default range setting for the Output 2 is 10 to 0 mA.

3.6 Optical sensor installation
When planning to install DST-1 sensor, please be aware the sensor’s
large field of view and working distance. Any elements of machine
frame in the view can potentially distract the sensor from the web
guiding. Maximize the web view and minimize the presence of nonrelated elements to web guiding process. See Table 1.
Sensor operation can be affected by changing light conditions, such
as ambient light changes caused by light sources with a rich IR
component (for example, morning or evening sun visible in window,
or incandescent and halogen lights in the sensor’s direct view).

or performed by personnel who do not have the authority.
Definitions for the purpose of this chapter:
Admin (or privileged operator) has a password and full access
to all menus.
Operator does not have a password and can only access
unlocked button functions.
Locked out = password protected
Login screen = password entry number pad/keyboard
Basic steps to activate security
- Enable a password
- Select the functions you wish to protect
- Set and save a password
- Log out of the Admin menu
All password security settings are reset to NONE after
restoring configurations from a backup source.

6.0 Sensor operating parameters
To aid in understanding the device configuration procedure, this
section presents the device structure, key parameters, their practical
functions and graphical representation on the OI screen.
DST-1 signal internal processing consists of three major system
elements, illustrated in Figure 13:
1) Acquiring a web image
2) Processing it
3) Generating output signal for a web guide system.
Note: Each function above has a "#" character next to it. This is a
placeholder for a number that represents each particular system
element, as there are more than one of each. The table below outlines
the quantity of each and their possible relationships combinations.
The signal processing element can produce a number of signals and
their combinations, extracted from a web image, and ready to be wired
to an output. There are number of parameters to be set, so any desired
signal is connected to a proper output. These parameters are divided
into two groups, "global" (not related to any job settings) and "job
related" settings.

6.4 Signal web processing parameters
These parameters configure web image processing algorithms.
They are unique for each signal.
From the main screen, select
SETUP > SETTINGS > JOB SETUP > MANUAL SETUP > OUTPUT 'N'
> select tab S1 or S2.
When a signal is enabled, its tab is bright. The
image shows S1 enabled and S2 in OFF state.
Because each output can have up to two signal functions
associated with it, each signal must have its own web processing
function.
Minimum configuration consists of one sensor, one signal and
one output.
Maximum configuration is allowed to have four signals (two for
each output). These parameters are divided into two groups:
Edge/Line detection, based on web material properties, described
as functions F1...F4. See page 32.
Region of Interest (ROI), based on specific areas of interest in the
web image. See page 33 for options.

6.4.2 ROI definition and configuration
Region of Interest, or ROI, is a very important set of parameters
for the web processing algorithms.
ROI is an element of the communication link between the
technician setting up the job and the sensor image processing
methods. ROI allows the sensor to focus on specific elements of
a web, and to track its edge or line movements.
The ROI parameter set includes the number of defined regions,
a description of their positions and behavior on the screen. Key
ROI parameters and their icon representations are listed in the
table below.
You can use the DST-1 OI touch screen to set ROI; see page 34.
ROI function
Icon
Description
Flip ROI button
User aid to define ROI orientation. Flips ROI from horizontal to vertical
and vice versa.
Free-hand ROI
User can reshape ROI and move it around the screen.
User can stretch ROI to some limits, which are the defined by the
sensor image processing function.
Dynamic ROI
Toggle function between Dynamic and Static ROI.
Dynamic ROI mode allows it to follow its target across whole horizontal
Field of View (FOV)
Static ROI
Toggle function between Dynamic and Static ROI.
Static ROI mode does not allow it to move horizontally across the
sensor’s FOV. This mode is useful when, for example, there is a
machine frame presence in the FOV, which can distract the sensor from
normal operation.
Synchronous ROI
This is a user aid that synchronizes changes made on one ROI to the
secondary ROI and vice versa. Its primary use is to make both ROIs the
same size.
Asynchronous ROI
Defines two independent ROIs, which can be dragged and set at key
web image locations. In this mode, each ROI is processed
independently and the result can be separate or combined output from
the sensor. Useful for center-guiding, web width measuring, etc.

6.4.3 Using DST-1 OI touch screen to set ROI
Example 1.
Defining ROI size.
Use two fingers to re-size and watch for the
maximum size limits.
Example 2.
Defining ROI position.
Drag the ROI with your finger over web edge/line.
If the Dynamic ROI setting is enabled, the
horizontal position will be controlled by the
configured edge location, and dragging the ROI
only sets the vertical position.
Both horizontal and vertical position may be set
when configured for Static ROI operation.
Example 3.
Two dynamic asynchronous ROIs defined as Signal 1
and Signal 2 for center-guiding on transparent
web material.
The web center signal is computed and fed to the
selected Output number.

Automatic setup procedure
Many opaque web materials use guiding settings that are
simple enough for the sensor automatic setup procedure.
The procedure is based on the following rules:
1) Auto-setup will overwrite the current job settings. If you
wish to save the current job, enable and select a new job
before running auto-setup.
2) Auto-setup procedure is expecting an opaque web
material.
3) The sensor output range is already pre-set by the user, see
Global Setup/Output Range menu (page 27).
4) The web is loaded in front of the sensor (see Figure 12 for
sensing element positioning). Auto-setup can distinguish
between right edge, left edge and center guiding.
5) Distance to the web is within recommended range; see
Figure 11. If center guiding mode is desired, both edges of
the web must be clearly visible on the OI screen.
From the main screen, select
SETUP > SETTINGS > JOB SETUP > AUTO-SETUP
Press to toggle between Outputs 1 or 2.
Press to start AUTO-SETUP.
The auto-setup process takes approximately ten seconds.
If successful, ROI edge marker(s) appear on the web image; the
AUTOSETUP header updates its status to COMPLETED.
Message window:
Sensor output is suspended during auto-setup. Continue?
Yes =
When auto-setup runs, the last known output signal is
frozen until the process is complete. When you save the
results of the auto-setup, the signal updates and
resumes output.
No =
Returns to the SETTINGS screen.

Manual setup procedure
Manual setup is used for web materials with special properties
or for setting a guide target at the specific place in a web.
The manual setup procedure works in the opposite direction
of the sensor data flow as described in the Sensor Operating
Parameters chapter.
Start with the Output selection and step through the signal
functions and individual signal definitions.
Figure 19. Signal data and manual setup flow directions
Each new job configuration consists of two separate sets of
parameters:
Camera backlight settings — can be edited and saved
separate from Parameter Group 2, Table 2.
Output and Signal settings — can be edited and saved
separate from Parameter Group 1, Table 2.
Both sets of parameters are part of the same numbered job.
When starting a new job configuration, the factory defaults
are loaded; they are listed in Table 2 on page 38.
