WebPro Unwind Brake Tension Controller
Batch Hold
This feature is used when winding small rolls from one large parent
roll, as for cash register or till rolls where the machine stops and
starts frequently. When enabled and the input is operated, the
output level from the Controller is held in memory on slow down
and the Controller output starts from this level when the input is
released. This prevents a tension dip due to the normal operation
of the "Soft Start" feature.
As shown alongside, the output will be held at the Pre Length and
will be released when the RESET LENGTH key is pressed.
System Set Up
The system must be set up before the Controller is used for the first time. The on screen prompts are very
easy to follow and will guide the user through the Controller system set up and commissioning. The
parameters can be easily changed later if necessary.
Press the SYSTEM SET UP key (called SET UP) to cancel an action or entry and return to the previous
screen. Press the CONFIRM key when finished with a screen to confirm the entries. If the CONFIRM key
is not pressed, the entries will not be saved to the memory and the existing parameters will be used.
Pressing CONFIRM will also exit that screen and return to the previous screen.
When entering Commissioning values and Product Parameters, some values are entered by the numeric
keys, some are entered by the +/- keys; this will be shown in the relevant sections later.
Use the Scroll keys to move the cursor up or down the menus. Enter a value using the ENTER key, the
cursor will move down to the next item. The CONFIRM key must be pressed to save values to memory.
When the Controller is switched on, the program is loaded, the company logos are shown briefly then the
Introduction screen below is shown. This sequence can be changed, see "Start in control screen" later.
