1 Introduction 1.1 Overview Welcome to Easy Coat® for Windows® XP (ECXP) Version 4.2. ECXP 4.2 is a Windows XP application specifically designed for use with Nordson ASYMTEK's Select Coat SL-94X conformal coating systems. This manual is an instructional guide designed for system operators, computer programmers, and process engineers. It provides a complete tour of the Easy Coat for Windows software with detailed explanations of all features. This section covers the following topics: 1.
1.5 ECXP Overview Easy Coat for Windows XP (ECXP) is Nordson ASYMTEK proprietary software for use in a Windows XP environment, developed specifically for conformal coating applications. Before the dispensing process can begin, the ECXP software must be installed and programmed to perform the necessary procedures. ECXP controls both the dispensing head (robot) movements and the dispensing operation in the conformal coating process. ECXP features include: 1.
Nordson ASYMTEK offers an automated solution to the conformal coating process by offering Automated Selective Coating. Unlike other methods, Automated Selective Coating achieves high throughput, dispensing consistency, and material savings with little or no masking. After the conformal coating has been applied, it must be cured or hardened (Step 2). The curing method depends on the coating material.
2 Installation 2.1 Overview In most cases, ECXP should arrive already installed and configured for your coating system from the Nordson ASYMTEK factory. The installation process is a typical Windows XP installation with user prompts. NOTE Refer to this section for first time installation only. Upgraded versions of ECXP include separate installation instructions. This section covers the following topics: 2.
2.4 ECXP Installation Procedure Most of the standard installation process is automated. You will be prompted to approve file locations and accept defaults. Since ECXP is a true Windows XP software package, installing ECXP follows standard Windows installation procedures. NOTE ECXP installation is performed at the factory prior to shipping. This procedure is included should the software need to be reinstalled. CAUTION! The ECXP installation procedure should be performed by trained personnel only.

Pressure can be displayed in graph or text format by clicking on the desired tab (Figure 3-12). Fluid pressure adjustments can be made directly from the Operator Screen.
4 Configuration and Characterization 4.1 Overview Your coating system is configured at the Nordson ASYMTEK factory prior to shipping. However, if any components have been changed or moved, it may be necessary to reconfigure them in ECXP. This section contains the following procedures: 4.
4.4 Tool Configuration A tool consists of a fluid dispensing applicator and nozzle. The Tool Configuration dialog box allows you to set the offset for each tool and perform a characterization. 4.4.1 Tool Offset Tool Offset is the X, Y, and Z distance from the lower tooling pin on the Z-slide (also called the tool flange, or tool arm) to the tool tip (end of nozzle). See Figure 4-1.
To define Tool Offsets: 1. Click on Configure > Tools from the Edit Screen menu bar. The Tool Configuration dialog box opens (Figure 4-2). WARNING! If Tool Offsets have already been defined and set up in the Tool Library, correct offsets are displayed in the Tool Configuration dialog box. DO NOT change them without assistance from your Nordson ASYMTEK representative. Your Nordson ASYMTEK application engineer can supply you with the offset coordinates for each tool used.
3. Load a board. 4. Place a piece of dilatant compound on the board. 5. Click Teach Relative in the Tool Configuration window for your selected tool. You will be prompted to select a reference tool (Figure 4-3). Figure 4-3 Selecting a Reference Tool NOTE 6. Click the 4-4 To ensure accurate positioning when teaching coating programs, offsets should be taught relative to the teaching tool. If a camera or laser pointer is in use, teach the offset relative to the camera or laser pointer.
Figure 4-4 Teaching the Tool Reference Point 7. Use small steps to move the tool so that the tool tip is in the dilatant compound. The tool tip should be deep enough to make a mark in the dilatant compound. Do not jog the robot because you may move the Z-head down too far and damage the board. 8. Click OK while the tool tip is in the dilatants compound. You will be prompted to move the reference tool to the same position (Figure 4-5).
9. Move the Z-head to its upper limit and position the camera cross-hairs/laser pointer over the mark in the dilatant compound. 10. Click OK. Offsets for the tool have been taught relative to the camera/laser pointer. Since the tool tip is usually in front of and below the tooling pin, the Y and Z offsets are typically negative. Positive X is to the right of the tooling pin as shown in Figure 4-1. 11. Repeat the above procedure for each tool.
4.4.2 Camera Configuration Configuring the camera creates a relationship between the pixel size seen on the screen and the distance that the pixel represents in terms of machine steps. This relationship will be unique for each physical setup because of variations in pattern heights, lenses, tolerance stackups, etc.
4.5 Characterization NOTE A characterization must be performed for each tool and each coating material used or as required to ensure quality and consistent dispensing. Many variables, such as material type, temperature, viscosity, substrate type, robot velocities, and dispenser response times affect the coating process. Characterization improves coating placement accuracy and repeatability. The Characterization Wizard helps you adjust program values to compensate for these variables.
To perform a characterization: NOTE Make sure you have selected the proper tool as the pointer in the Edit Screen (Figure 4-8). This is the tool that will be used to teach the positions. If the system is configured with a Genie Camera or a Laser Pointer and you are going to use one of these to teach positions, make sure it is selected. Figure 4-8 Selected Pointer 1. From the Edit Screen, click on Configure > Tools. 2.
Figure 4-10 ECXP Characterization Wizard Dialog Box 3. Click Clear Positions and then click OK to confirm. If you have performed a characterization before, the old test area coordinates are used unless you clear them. 4. Click Next. 5. Click Yes when prompted to teach the substrate height. 6. Teach the substrate height. a. Place a characterization sheet (Figure 4-11) in the workcell. b. Lower the tool tip to the substrate and click Teach Z. c. Click OK. 7. Enter the dispense height.
10. Position the tool tip or camera over the left intersection of the dotted lines and click Next. 11. Position the tool tip or camera over the right intersection of the dotted lines and click Next. 12. Position the tool tip or camera over the right dotted line and the back line and click Next. Remove any teaching devices before continuing.
13. Click Next. The Wizard will now apply three stripes of material to the test area (See Figure 4-12). Desired Start Desired End 2nd 3 passes 1st 3 passes Figure 4-12 Material Characterization 14. You will be prompted to teach the coordinates of the test area. a. Teach the stripe with the best starting accuracy and click Next. If none are exact but one stripe starts too soon and the next too late, teach between the two stripes. The wizard interpolates the values of the two. b.
4.6 Fixture Configuration Fixture refers to the location at which products are physically constrained in the workcell. It consists of both position (XYZ) coordinates and a corner constraint (Front Left, Front Right, Back Left, or Back Right). On conveyorized systems, the fixture is typically the combination of a clamp and a stop. On nonconveyorized systems, it is usually a manual fixture. 4.6.
4.6.2 Configuring a Fixture on Systems Equipped with a Camera To configure a fixture on systems equipped with a camera: NOTE If necessary, install the fluid dispensing applicator. The applicator must be installed before teaching the X-coordinate and Y-coordinate. 1. Press [F4] to open the camera viewing window. 2. Resize the ECXP Operator and Edit Screens so that the camera window cross-hairs are visible at the left side of the screen, behind the Operator and Edit Screens. 3.
6. Teach the coordinates as described below. See Figure 4-17 for coordinate locations. This example is for a front-right constraint, which is the normal setting for a left-to-right conveyorized system. a. Move the robot until the camera crosshairs are directly over the constrained board corner. b. Click Teach X to teach the X-coordinate and click Teach Y to teach the Y-coordinate. 7. Click Close to exit fixture configuration. 8.
4.6.3 Configuring a Fixture on a System Not Equipped with a Camera To configure a fixture: NOTE Before configuring the fixture, you must configure the Tool Offsets.

5.5 Mask Regions Mask Regions are areas on the board that should not be coated. Mask Regions simplify the programming process. For example, if the entire surface of a board except for two small connectors is to be coated, you can create one Area Coat instruction to coat the board and two Mask Regions to skip the connectors, instead of programming numerous passes that avoid the connectors. A Mask Region is a rectangle, defined by two points at opposite corners.
Periodic1 to PeriodicN procedures execute based on their timers only. To use Periodic1 to PeriodicN procedures, you must create procedures with the same names. The Startup procedure executes at ECXP startup after the robot moves to its home position. To use this procedure, you must create a procedure named Startup. In order for it to run, it must be in the macro or product program loaded when ECXP is shut down. Reserved procedures are included in the Macro1.ECM program included with ECXP. To open Macro1.
5.6.1.1 Idle Behavior Idle behavior is defined by the instructions in the Begin Idle, During Idle, and End Idle procedures. These procedures allow a sequence of operations to be performed whenever products are not being coated. These procedure names are reserved and can only be used for idle behavior. Only an error or operatorinitiated stop prevents the idle procedures from executing. The Begin Idle procedure is executed when the Idle Timer expires. The timer starts when production stops.
5.6.1.3 Periodic Behavior Periodic behavior is defined by the instructions in the Periodic procedures. These procedures allow a sequence of operations to be performed periodically during production. The procedure names are reserved and can only be used for periodic behavior. Periodic procedures are named Periodic, Periodic1, Periodic2, Periodic3, etc. A Periodic procedure is executed when its periodic timer expires.
5.7 Reference Frames All positioning in the workcell is done with reference to sets of position coordinates, called Reference Frames. In ECXP, three different sets of reference frames are used: Base Frame, Product Frame, and Pattern Frame. See Figure 5-4. As you face the front of the workcell, the X-axis is left to right, the Y-axis is front to rear, and the Z-axis is up and down. The X, Y, and Z limit switches at the front left corner of the Base Frame define the Home or Origin position of the robot.
5.7.2 Product Frame Product Frames (See Figure 5-4, Rectangle B) exist within the Base Frame. ECXP uses fixture constraint coordinates, plus the length and width of the product, to calculate the coordinates of the Product Frame within the Base Frame. The Product Frame origin is the calculated Main Pattern Edit Frame. 5.7.3 NOTE A product can be a board or a pallet (carrier) containing one or more boards. If a pallet is used, the dimensions of the pallet are used to calculate the Product Frame.
Property fields can contain one or more of the following buttons in addition to numeric and text values. See Figure 5-6. List More - Displays the Conditional Editing window. Allows you to enter additional settings for Set Outputs, If, and While instruction properties. Teach Field - Causes a drop-down menu to appear that lists possible values for the property. Click on a value to enter it into the field. - Enters the current X-, Y-, or Z-coordinate of the active tool tip in the selected field.

See 4.18 Maintenance Manager. A maintenance procedure is created like any other procedure, however an Ini File Write instruction must be included in the Main Pattern (Figure 5-29). This instruction writes the key and the time and date stamp to the ECW.ini file.
5.9.9 Placing Patterns All patterns except the Main Pattern are executed by the Place Pattern instruction. The Main Pattern is executed when the program is run and all program instructions are executed from the Main Pattern. Mask Regions do not need to be placed since they are associated with a particular pattern. The Main Pattern is placed at the Product Frame origin, which is the front left corner of the workpiece. See 5.7 Reference Frames. To place a pattern: 1. Highlight the Main Pattern.
5.9.10 Calling Procedures In order to run a procedure, you must place a Call Procedure instruction in a pattern. To call a procedure: 1. Highlight the pattern or procedure in which you want to place the Call Procedure instruction. One procedure can call another. 2. Click on the Call Procedure button to create the instruction. button in the Procedure Name property field, and select the procedure 3. Click on the List you want to call. See Figure 5-32.

5.13.2 Creating Images The Graphic Display supports JPEG and BMP formats only. Image files can be created with a digital camera or exported from CAD programs. Bitmap resolutions of 640 x 480 or 800 x 600 are sufficient for most purposes. Higher resolutions result in larger file sizes, which could cause slow refresh rates in ECXP. If you use a digital camera to create board images, place the boards on a light background before taking pictures.
To crop an image: 1. Drag three corner handles to their respective corners of the board, aligning the cursor crosshairs with the corners. For more precise handle placement, click inside the magnified crosshair window. See Figure 5-33. Clicking near the corner of the board will snap it to the crosshairs. Each time you drag a handle to a corner of the board, the image of the board is redrawn. 2. Hold down the [Ctrl] key before clicking and dragging the last corner.
5.13.5 Graphic Display Features After you have created or imported an image, you may pan, zoom, resize, and undock the image as described below. 5.13.5.1 Panning To pan an image: Right-click on the image and drag to move the image around in the display. 5.13.5.2 Zooming To zoom in on an image: 1. To zoom in, left-click on the image and drag down and to the right. The area surrounded by the marquee will be magnified. 2. To zoom out, left-click on the image and drag up and to the left.
2. To maximize the image, refresh by clicking on any other pattern or procedure in the Program Structure Tree and then clicking back on the current pattern as shown below. 5.13.5.4 Undocking/Redocking Undocking places the image in a separate window and provides greater flexibility for enlarging and zooming in on the image. To undock an image: 1. Move the cursor to the undocking bar. The undocking bar is represented by the two vertical lines on the left border of the Graphic Display. See Figure 5-37. 2.

Move the cursor to the end point and press [Ctrl] left-click again. 13. Repeat Steps 10 through 12 and coat another section of the board.
5.13.7 Using Graphics Display to Program Both Sides of a Board Program images are imported with File > Import Board Image > First Side > Second Side. The Second Side is used when the board or pallet is inverted. If you import both First Side and Second Side images, both images will be displayed in the Graphics Display simultaneously only when you have the Main Pattern selected and an Invert instruction is present in the Main Pattern. Only the First Side image is displayed on the Operator Screen.
5. Undock the image and enter pattern instructions for "Side 1." See 5.13.6 Using the Graphics Display for Programming. 6. Click on Save . 7. Repeat Steps 2 to 6 for the second side of the board. Replace "Side 1" references with "Side 2". NOTE For most applications, you will only use one image, imported with the Image Name 1 property. The only time you will import an image with the Image Name 2 property field is if you have an Invert instruction in the pattern. 5.13.7.

6 Troubleshooting 6.1 Overview If you have difficulty running your coating programs, use this section to identify a possible solution to the problem. If you have difficulties not listed in this section, or the suggested solution does not correct the problem, contact Asymtek Technical Support. This section covers the following topics: 6.
6.3.1 Program Does Not Run With the Edit Screen open, an error will cause a dialog box to display “Program had Error.” See Figure 6-3. In most cases ECXP will toggle to the procedure or pattern with the error and will mark the instruction that caused the error with a blue arrow. Click OK and then switch to the Operator Screen to view the Event Monitor. If the program does not run, make sure that Place Pattern and/or Call Procedure instructions have been placed in the Main Pattern.
6.3.2.1 Not Found Errors If ECXP fails to find a procedure or pattern, it displays an error message that includes the name of the procedure or pattern not found. This error message occurs: If the procedure called by a Call Procedure instruction is not in the loaded macro program. If a Place Pattern or Call Procedure instruction was not included in a pattern or procedure. If a Place Pattern or Call Procedure instruction was inserted without selecting a pattern or procedure to place or call.
6.3.4 Arc Errors If the angle of the arc is more than a full circle or 360º, an error will be generated. The Robot can only travel 360º at a time, so it cannot ramp up and down. If this error occurs reduce the Start Distance and Stop Distance property values (they may need to be zero if it is a full circle) until the error disappears. In addition, if an arc command has too tight a radius for the set velocity and acceleration, an error message will be generated.
6.6 Z-Axis Related Errors If the error is Z-axis related, be sure to check all Z-axis related properties including Approach Height, Depart Height, and Dispense Height. Also, check the system Safe Z Height (Utilities > Robot) as it is used before executing anything while in the Edit Screen. If a conformal coating instruction (Spot, Coat, Area Coat) is used in a procedure in which all position coordinates are relative to the Base Frame, you may see this error.
6.8 Fan Width Control Errors The Fan Width Control option has sensors that detect and measure the fan pattern and fluid pressure controls to adjust fan width and keep it within programmed tolerances. The fan width instructions can be included in procedures or programs to periodically measure and control the fan width. Fan width tolerances are set by the programmer with Error and Warning offsets during the Fan Width configuration procedure (Configure > Fan Width Setup).
Appendix A Instruction Quick Reference Overview This appendix provides a brief description of ECXP program instructions grouped by category. Refer to Appendix B for detailed information on program instructions, instruction properties, and syntax. Tab A-201 Conveyor Button Instruction Description Send ACL Sends an ACL command to the Conveyor Controller. Coat Specifies a single coating pass, in a straight line. Begin and end coordinates must be specified.
Tab Control (Continued) Fan Width Control Inverter Button Instruction Description Repeat Instructions between Repeat and End instructions are executed a set number of times. Creates a loop between the Repeat instruction and the End instruction. While Instructions between a While and an End instruction are executed as long as the While condition is True. Creates a loop between the While instruction and the End instruction. Pattern Array Repeatedly places a pattern on a rectangular grid.
Tab Button Instruction Terminate Program Ends program with error (returns False to Robot Controller). Can be used to stop program. If this instruction is executed during production, production will be stopped with a "Coating program had error" message. Add Fault Use this instruction to add a clearable fault message to the operator display. This instruction is typically used in user-created error handling procedures, which have no pre-programmed fault messages.
Appendix B Instruction Properties Overview This appendix alphabetically lists all ECXP program instructions, descriptions, syntax (if applicable) and instruction properties. Abort Program Description: Ends program with error (returns False to Robot Controller). If this instruction is executed during production, production will be stopped with a "Coating program had error" message.
