1. The control unit
The control looks as follows:
The precise appearance of your control may differ.
Operation of the control is mainly done over the touchscreen. A description of the functions and available touch controls is given in the next sections of this manual, aside of the description of the specific functions.
Beside the touch controls the front of the control consists of an emergency stop, the handwheel and the start and stop buttons.
Special function keys, which can be mounted in the top panel of the control, have their specific description parallel to this user manual and will be supplied by the machine manufacturer.
This user manual focuses on the control software and related machine functions.
2. Front control elements
The frontpanel, beside display, consists of the following control elements:
3. USB connectors
4. Operation and programming modes
The control's main screen looks as follows:
Depending on the navigation button which is active, the screen will differ. The above main screen will appear having the Products function active.
Just by tapping the various modes, the specific mode will be selected.
The structure of the main screen is as follows:
In the top the title panel is always shown. In this area you can find logo information, which product is loaded, the selected products directory and (when activated) the service row. Also machine indicators can be found here.
In the information panel all functions and visualisation related to the selected modus are displayed and can be found.
The command panel is part of the Information panel and is the location where the controls related to the Information panel can be found.
The Navigation panel is the area where all the major modes can be found. This area is always visible. The controls, large buttons with icons, can be used to directly switch from one mode to the other.
Explanation of the main modes / navigation buttons
5. Getting started
In order to obtain a bend program for a product, the control offers the possibility to create a product drawing and calculate a valid bend sequence for the product. With this information, a product program is generated.
This is done with the following steps:
● Go to the Products mode in the navigation panel and start a new product by tapping New Product.
● Enter the product properties and start to draw a 2D product profile in the Drawing mode.
● Check the tooling, modify or make a new set-up in the Tool Setup mode.
● Use the Bend Sequence mode to determine the bend sequence by calculating it or manually modifying it upon your own idea's.
● When required modify the numerical CNC program via the Program mode.
● Tap Auto and press the Start button in order to produce the programmed product.
Before product programming can be started, the following preparations must be made.
● The correct material properties must have been programmed in the Materials library. You can find this on the Materials page in the Settings mode.
● The correct tools must be programmed in the Tool Library. Tools are necessary to create a CNC program. You can find the libraries for the different types of tools in the Machine mode.
(3)Create a drawing
The control offers the functionality to create a drawing of the intended product. With this drawing application, tap Drawing in the navigation panel, a 2D profile or 3D product drawing is created. At this stage, there is no calculation of bends or dimensions: any profile or drawing can be created.The drawing method on the Touch screen control is based on:
● Value setting
The product as well as tool shape Sketching can be done by tapping on the screen in the different directions the drawing must have. The application will follow the tapping with drawing a line between the indicated points. The last point of the design will show always a big red dot.
When the drawing dot is on the screen you can hold your finger on this position and move the finger across the screen to move the connected line in another required direction or make the line length longer. This method is the so-called 'Dragging' facility. The length and angle value will be visible on the screen and can be adjusted to be exact or close to the requested value.
Once the product or tool is drawn in the Sketching method the exact values of line lengths and angles can be optimized by the Value setting method. Just tap 2 times on the value of the line length or angle to change and the keyboard will pop-up. The value can be entered in 2 ways
● Enter function
● Enter-Next function
The Enter function will close the keyboard after entering the value. The Enter-Next function will enter the value on the line or angle to change and the keyboard will remain opened for the next programming step.
In case the typed value is erroneous, the “undo” button right from the input field can be tapped to return to the original value or the backspace key on the keyboard to delete the last typed character.
By pinching the screen with two fingers simultaeously one can zoom in and out on the drawing, tool or machine visualisation. By spreading fingers the system will zoom-in, by bringing fingers nearer to each other the system will zoom-out.
In the command icons on the side of the screen you will find a Fit-To-Screen function. This can be used when the drawing size is not clear in picture. Just tap once and the complete drawing will be sized to fit the drawing screen.
With simultaneous touching of two fingers and draging them over the screen (sliding in the same direction) one can pan the object in 3D view. In 2D a single finger will also enable panning.
In 3D, rotating the product, tool or machine visualisation, can be done with a single finger sliding over the screern.
More information about this can be found in chapter 3.

(4) Determine bend sequence
When the product drawing is completed, the control offers Tool setup mode to program the exact tool set-up as it is organised on the machine. After this you can select the Bend Sequence mode to determine and simulate the required bend sequence.
In the Bend Sequence mode, the control shows the product, the machine and the tools. In this menu the bend sequence can be programmed and checked visually. When a bend sequence has been determined, the CNC program can be generated.
More information about this can be found in chapters 4 and 5.
Bending sequence computation
• Automatic computation for minimum production time
• Interactive bend sequence determination
• Manual bend sequence determination
• Collision visualization of product with tools and machine
• Free tool and machine shape selections
• Assignments of turn times, backgauge speed etc.
• Blank length computation
• Production time indication
• Bending sequence simulation
• Programmable finger positions
(5) Numerical program
The Program menu gives access to the numerical program and values of the active product.
There are two possibilities to create a CNC program:
• enter a numerical program, started via Products mode, tap New Program, step by step;
• generate the program from the graphical bend simulation started via the Products mode, tap New Product, via the Drawing mode. (see: Drawing mode; product drawing).
If the program is entered by hand, there is no collision check. All program values must be entered manually. The program depends on operator experience.
If the program is generated from a graphical bend sequence, the program can be visualised during production. A generated program can be edited according to operation needs.
More information about this can be found in chapter 6.
When a drawing has been completed with a bend sequence, and the program is stored, the program is post processed and the numerical program becomes available.
The system automatically computes :
• Necessary force
• Machine adjustments such as:
• Y-axis position
• X-axis position
• X-axis retract
Axes positions are calculated according to the machine configuration.
(6) The Auto menu and Manual menu, production modes
A product program can be executed via the Auto mode. In Automatic mode, a complete program can be executed bend after bend. In the Auto mode the Step mode can be selected to have each bend started separately.
The Manual mode of the control is an independent production mode. In this mode, one bend can be programmed and executed. It is typically used to test the behaviour of the bend system.
More information about this can be found in chapters 7 and 8.
(7) Back-up data, external storage
Both product and tool files can be stored externally. Depending on the configuration, these files can be stored on a network or on a USB stick. This facilitates a back-up of important data and the possibility to exchange files between Delem controls.
More information about this can be found in chapter 9.
6. Programming aids
(1) Help text
This control is equipped with an on-line Help function. When the Help-button in the navigation panel is pressed context sensitive help will be provided.
To activate a help window for a parameter tap the Help button in the navigation panel.
A pop-up window appears with information on the active parameter.
This Help window contains the same information as the Operation manual.
The help window can be used as follows:
You can scroll through the text sliding one finger in the desired direction. By tapping on the lower or upper part of the screen Previous Page / Next Page can be used to browse through the help text.
The Index function helps to jump to the table of contents. Hyperlinks in the table help to directly navigate to the desired topic.
Tap End to close the Help window.
(2) Listbox functionality
Several parameters on the control have a limited number of possible values. When selecting such a parameter, by tapping the parameter line on the screen, the list of options will open up near the position where you tapped the line, and the desired value can be selected.
To undo the selection and the opened listbox, tapping outside the box will make it close without changing the selected parameter.
(3) Filter, live search, auto filter
In some modes a list of entities is offered (products, tools, materials, etc.). An example of such a menu is the Products mode (product selection). To search a particular product or tool, the filter function can be used. Press the command button Filter, type a part of the ID in the enter field. Automatically, the list is limited to those items that contain the typed part.
Multiple search parts can be separated by <space>.
To close an open filter screen use the keyboard-close button on the right side next to the keyboard.
In addition to the filter function the column headers of eg. the tool selection tables and the product selection table have ‘auto-filter’ functionality.
When tapping the column header one can sort the list based on that specific column. The triangle in the header is shown as an indication of the sort order.
When tapping a header with auto-filter functionality a list box will be shown automatically offering the possible options for filtering, derived from the available entries in that column. E.g.
when using this in a die selection, the V-opening can be filtered to the desired value as searched for. The list will only show dies complying the set filter.
Filters can be switched of in a similar way. The list also offers a remove filter function.
Within some modes, the program screens are divided into tabs.
The tabs can easily be selected by just tapping them. When a tab is not completely visible or not visible at all, just by dragging the tab row horizontally, the desired tab can be "pulled" in sight and be selected.
(5) Text input and editing
The cursor can be used to enter a specific value or text within an existing input. Just tap at the desired position to do so. The cursor will appear and input will be added there.
E.g. in Edit notes, where multiple lines can be entered Enter is used for linefeed. Cut, Copy and Paste are offered on the keyboard for editing convenience. Undo and Redo can also be used within this editor.
The keyboard can be shown or hidden in this multiline editor using the arrow key in the lower left corner.
(6) Typing alphanumeric characters vs. special characters
Both alphanumeric characters and special characters can be used throughout the control. A full on-screen alphanumerical keyboard will pop up when required.
When editing a field which is pure numeric, the alphanumeric characters will be "greyed-out" and only the numerical keypad can be used. For fields which enable to use alphanumerical strings, the keyboard is completely available. Special characters as ? % - can be found using the special character button on the left-lower side of the keyboard.
Special characters (like á, à, â, ã, ä, å, æ) are supported by the on screen keyboard by keeping a character (like ‘a’) pressed.
The CNC control is providing a “desktop calculator” available for the operator.
At the top of the screen the calculator icon can be used to switch to calculator functionality.
The keyboard area provides calculator functions which can be used autonomously. Standard functions (add, subtract, multiply and devide) including percentage, square root, square and memory functions are available.
In case calculations should use parameter values as an input, and results as an output, one can switch to the calculator from the parameter entry. This will bring the parameter value to the calculator, and the result back to the input line.
No cutting or pasting is necessary. Only when entering and confirming the calculated value in the parameter entry line, it will be used forward.
(8) Messages centre
When messages are displayed coming from PLC, Safety systems, LUAPs or the Sequencer, these messages can be ‘send’ to the 'Messages centre'. When a message is displayed simultaneously the message centre symbol is shown in the top row of the page header, next to eg. the calculator and keylock symbol. When tapping this message centre symbol the messages are taken from the screen, giving way for normal programming and editing.
When tapping again the actual messages are shown.
When messages are in the background, the message centre symbol has an extra indicator to show new incoming messages which are not yet shown.
The CNC control is equipped with a network interface. The network function offers the operators the possibility to import product files directly from the network directories or to export the finished product files to the required network directory
Chapter 9 about backup/restore in Settings mode contains more information about networking possibilities.
(10) Keylock function
To prevent for changes to products or programs, the keylock function offers the possibility to lock the control.
There are two levels of locking the control. Program Lock and Machine Lock.
• In Program Lock, only a product can be selected and executed in Automatic mode.
• In Machine Lock, the machine is locked and the control can not be used.
To lock a control just tap the lock symbol in the top of the screen. Depending on the code which is used, the control will be in Program Lock or Machine Lock. Program Lock wil show a closed lock in grey. Machine lock will show the same lock but colored (red).
(11) OEM function panel
Depending on machine manufacturers implementation, the upper right corner of the screen can be used for special indicators.
To access functions related to those indicators, the OEM function panel can be opened by tapping this corner of the screen.
(12) Software versions
The version of the software in your control is displayed at the System Information tab in the Machine menu.
