1USER INTERFACE OVERVIEW
Figure 1 – STEADYWEB™6 USER INTERFACE
1.1 MAIN INTERFACE DESCRIPTION
The Steady Web 6 accepts all instructions and displays all information via a 5" touchscreen display (Fig.
1). All controller functions are context driven, and operate with color-coded buttons on the display. There
are no mechanical knobs, switches or buttons to operate.
For ease of use, the locations of the critical-use buttons/critical-awareness indicators have been made
uniform from one screen to the next. Those uniformly located buttons / indicators (Fig. 2) include the
following:
1. Tension On/Off, Auto/Man (Manual), and Display toggle buttons (all colored blue and at the bottom of
the screen). The only time the On/Off toggle button displays as anything other than On/Off is when the
controller is placed in E-STOP by an external input. When in E-STOP, the On/Off button displays as E-
STOP, and may only be restored by clearing the E-STOP signal, external to the controller. There are no
functions within the controller which will permit over-riding an external E-Stop signal.
2. Line Speed, Taper, Ratio, Soft Start and Hold (Sample & Hold) mode status indicators on the
information line above the toggle buttons, when active.
3. TLS indicator and Roll Diameter indicator, left and right of the tension display, above the information
line, when applicable.
4. Tension On/Off Status (upper LH corner) and Man/Auto Status (upper RH corner)

Figure 2 – LOCATIONS OF TOGGLE BUTTONS / INDICATORS IN DISPLAY
All screens, settings and adjustments which are not primarily tension-displaying functions require some on-
screen navigation to access them.
The remaining button in the lower right hand corner of the screen is green and displays as either “Menu”,
“Back” or “Save” depending on what screen is current, and is used to advance to other menus, to back out
of menus, or to save selections or adjustments.
Green buttons on menu screens indicate
selectable functions. When there are more
buttons in a menu than fit on the menu screen, the
excess buttons are off-screen, but the menu
screen may be shifted to reveal them by pressing
arrow buttons at one or both ends of the screen
(Fig. 3). If there are no arrows at the end of the
screen, then there are no off-screen buttons to
reveal.
Holding a green button down will bring up
related information, which effectively serves as an
on-screen manual.
Grey buttons indicate functions that may not be
selected until certain conditions are met. If in
doubt about why a button is grey, it may be pressed and held to view the explanation. Sometimes meeting
the necessary conditions requires permission-based access and actions in accordance with the Technical
Reference Manual (DFE P/N 801-2540).
On navigation screens, pressing the Back button will return the prior screen. If the Back button has been
replaced with another function, the use of which is not desired, the screen may be exited via the Display
button instead.
In the unlikely event of a screen failure, an always-on Power LED (Fig. 1) on the front of the controller will
inform the operator if the unit is still powered up.
1.2 DISPLAY MODE DESCRIPTIONS
To display the tension setpoint, real time tension and related process information, the Tension Display
mode should be used when making product, and the Menu Display mode should generally be used when
making changes to the process. When in Tension Display mode, pressing the Menu button will switch to
the Menu Display mode. Likewise, when in Menu Display mode, pressing the Display button will return the
screen to Tension Display mode.
TENSION DISPLAY MODES: Two different screens are available in Tension Display mode. Tension can
either be displayed as a momentary value on an analog meter (Fig. 4) or as tension vs. time in a trend-line
plot (Fig. 5) and may be toggled back and forth by pressing the Display toggle button.
Operator-adjustable display settings include Tension Update Time, Display Damping, Plot Update
Time, Line Speed Display, Diameter Display and Display Brightness, the adjustments of which are
described in Section 2.2, DISPLAY ADJUSTMENTS.

1.2 DISPLAY MODE DESCRIPTIONS continued....
1. Analog Meter - The analog meter displays tension with a bold needle sweeping across similarly bold
divisions in the form of a traditional analog meter, and is the default display (Fig. 4). The meter scale is
determined by the full range tension value. This easily read analog meter is further enhanced by a large
digital tension readout in the center of the screen, and expresses the measured tension in white
characters. The auto tension setpoint is indicated by a yellow caret atop the smaller divisions of the
analog meter.
The controller output, when tension control is on, is indicated as a percentage of full output to the left of
the meter scale, above the On/Off button. When tension control is off, this indicated as the manual
setpoint instead.
When Taper is active, a blue caret, also found atop the smaller divisions of the meter scale indicates the
dynamic tension setpoint.
When TLS Low and / or TLS High are active, those limits are indicated by blue and red carets
respectively, atop the larger divisions of the meter scale. For more details about TLS, see Section 2.6,
TLS ALARMS AND RESETTING THEM.
2. Trend-line Graph - An alternative to the analog meter, the tension trend-line graph (Fig. 5) plots both
the tension and the controller output versus time, from right to left. Since the plots of tension and
controller output can cross or overlap each other, the controller output is plotted as a line, and the area
below the tension plot is filled in, with both sets of data plotted in contrasting colors for improved clarity.
The plots of the tension and output are keyed to a legend in the left margin and the auto tension setpoint
is identified by a yellow caret in the right margin of the trend-line graph. If Taper is active, and auto
tension control is on, the dynamic tension setpoint is indicated by a “T” moving in the right hand margin
of the display.
The time it takes for the trend-line to cross the screen is the Line Graph Update Time, and is
selectable as 30 seconds or 1, 2, 5, 10 or 30 minutes, per Section 2.2, DISPLAY ADJUSTMENTS. The
greater durations allow for a greater data sample, but with a loss of resolution.
The trend-line may also be paused by holding down the Display button until the trend-line stops
moving across the screen. Plotting will resume when the Display button is pressed again. Tension data
for the paused period will not be recorded, and may not be retrieved.
When TLS is used, neither TLS Low nor TLS High Limits will be indicated on the Trend-line graph. If
either tension limit switch is tripped however, the on-screen alarms will still be issued, and must be
cleared according to Section 2.6, TLS ALARMS AND RESETTING THEM.
This trend-line graph display also appears repeatedly in the Technical Reference Manual (DFE P/N
801-2540) on PID Tune View displays which allow for real-time P, I, and D adjustments while viewing
the controller output and tension.
1.3 MENU MODE AND NAVIGATION
From either of the tension display screens, the Menu button will deliver the operator to the Main Menu (Fig.
6) where subordinate menus appear for further navigation. Note that the names of all menu screens are
consistently displayed at the center of the top line.
