EFD® TT User's Guide Version 1.2 1.2 MACHINE MOVEMENTS The EFD® TT dispensing system uses an advanced microprocessor to simultaneously control three axes of motion. An optical encoder feedback system provides closed-loop control to accurately position the dispensing tip whether dispensing lines, dots or contoured paths. X Axis The EFD® TT Automation system is a three-axis fluid dispensing platform. The three degrees of freedom provided are X/Y/Z. The motions are indicated in the figure to the left.
EFD® TT User's Guide Version 1.2 2 Setup 2.1 Preparing the Work Area Place the EFD® TT system on a stable table or bench. The EFD® TT needs enough space behind the machine (at least 250mm) to allow for the tooling to move to its home position. This space also ensures the fan duct on the back of the machine is not obstructed and thereby allows for air-cooling of the internal electronics. Allow enough room to place fluid reservoir pressure tank beside the machine.
EFD® TT User's Guide Version 1.2 2.3 MOUNTING WORK-HOLDING FIXTURE Use the four tapped (4) M4 holes on the Y-Carriage to mount your work-holding fixtures. It is important your work-holding fixture is mounted on the Y-carriage in a manner that it is parallel to the X-beam. Flatness of your fixture is important because it makes programming much easier.

EFD® TT User's Guide Version 1.2 2.5 VALVE/SYRINGE BARREL CONNECTIONS The following chart summarizes how different EFD valves/syringe barrels should be connected to the Z-head. Note that if more than one valve/syringe barrel is required for the application, a separate dispenser controller for each addition will be required. The EFD® TT system is a self-contained fluid-dispensing positioning system. It features integrated dispensing functions to operate any EFD valve or syringe barrel.
EFD® TT User's Guide Version 1.2 2.5.1 SYRINGE BARREL This section also applies to EFD dispensing valves 5800MP, HP4X, and HP7X, in addition to EFD’s range of syringe barrels. First, install the appropriate bracket e.g. universal syringe barrel bracket (P/N 700814) for syringe barrel installations, onto the Z-carriage. Insert the holding pins into the holes on the back plate to fit the size syringe barrel you are using.
EFD® TT User's Guide Version 1.2 2.5.2 SINGLE AIR INPUT VALVE EFD's single-air input valves include 752V-UHSS, 725DA-SS, 725HF-SS, 740V-SS, and 736HPA. Install the corresponding valve mounting fixture to the selected valve and then install the mounting fixture onto the Z-carriage. Refer to Section 8 (EFD® TT Accessories) for the entire list of EFD valve mounting fixtures. Attach the pulsed-air line to the P1 connector on top of the Z-head.
EFD® TT User's Guide Version 1.2 2.5.3 MULTI AIR INPUT VALVE Nordson EFD's multi-air input valves include 780S-SS. Install the corresponding valve mounting fixture to the selected valve and then install the mounting fixture onto the Z-carriage. Refer to Section 8 (Accessories) for the entire list of EFD valve mounting fixtures. The pulsed air for valve operation plugs into the P1 connector on the Z-head. Set the air pressure on P1 Gauge/Regulator to 70 psi.
EFD® TT User's Guide Version 1.2 2.5.4 ELECTRIC AUGER VALVE Install the Auger valve onto its corresponding valve bracket (P/N 700806) before attaching onto the T-slots of the Z-carriage. The Auger valve uses a brushed DC motor and requires two electrical connections into the 4- position terminal block located on top of the Z-Head. The positive (+) white wire goes to terminal 1 and the negative (-) brown wire goes into terminal 2.
EFD® TT User's Guide Version 1.2 2.6 MOUNTING LASER POINTER Some customers may prefer to use a laser pointer to aid in positioning the X or Y dispense programming points. Note that the laser pointer should be used in conjunction with the height sensor. The height sensor, along with the dot/line parameter setting of the “dispense gap” will determine the z-height at the dispense point. EFD provides a laser pointer and bracket (#700820) that can be easily mounted onto the EFD® TT.
EFD® TT User's Guide Version 1.2 3 PDA Before you can start programming, you must first install the Nordson EFD® TT PDA software Version 1.2 to your PDA. Download the Software Installation CD that was included with the PDA to the PC. Once that is done download the EFD PDA software to the PC. Copy the EFD PDA software to the palmOne Quick Install and then HotSync to install the EFD PDA software to the palm. Currently, only selected PDA handhelds6 can be used with the Nordson EFD® TT programming software.
EFD® TT User's Guide Version 1.2 important notes Recharge PDA and sync it to your computer at the end of every day. Otherwise, you may lose the information entered since your last sync session. The next time you want to connect to the EFD® TT using the same PDA, launch the Nordson EFD® TT PDA application. When asked if you wish to reconnect to the last device you communicated with, select “Yes” and go through the reinitialization steps.
EFD® TT User's Guide Version 1.2 4 SYSTEM CONFIGURATION After performing the discovery and pairing of the PDA and the EFD® TT (Section 3), go into the Setup screens to configure your EFD® TT system for the specific valve/syringe barrel setup appropriate for your fluid dispensing application. You have to complete this setup first or you will not be able to program the dispensing pattern correctly. From the Main screen, tap “Setup”. This will take you into the Setup screen.
EFD® TT User's Guide Version 1.2 4.1.1 Valve #1 Next, select the model of Valve #1 from the drop-down menu. This software allows for specific settings to be configured for each valve in the Valve Options screen. Make the appropriate selections for the application requirements. Example 1: The 780S Valve Options screen allows the User Operator to specify nozzle air on/off delay. Note: the default is a 0.24/sec nozzle air delay, but this setting is configurable from 0 to 5 seconds in 0.01 sec increments.
EFD® TT User's Guide Version 1.2 4.1.1.1 Teaching Tip to Probe Offset This is an optional function. You will need to teach the dispense tip to probe offset only if you intend to use height sensor commands within the program. It is recommended you use the height sensor if your application requires very small dots or fine lines. The tip to probe offset allows you to teach the height difference between the tip and the height sense probe (which is essentially also the surface of your part).
EFD® TT User's Guide Version 1.2 4.1.2 Toggle Valve If a Toggle bracket is selected, you will also need to teach an offset for the toggle valve. Follow the instructions in Section 4.1.1.1 to teach offset for the Toggle Valve. However, prior to teaching the offset, the toggle valve bit configuration must first be completed. 4.1.2.1 Configuring Toggle 1. At the Setup screen, tap "Setup" at the upper left-hand corner of the screen. 2.
EFD® TT User's Guide Version 1.2 4. Select the Assertion Level, which defines whether a “1” or a “0” written to the Output Bit will cause the toggle bracket to move down. 5. Tap “Up” or “Down” to test the toggle bracket for the proper Output Bit and Assertion Level. 6. Tap “OK” to return to the Setup screen. 7. Now select “Actuation Output” from the Setup drop-down menu. 8. The Valve Actuation configuration screen allows the user to select which output will actuate the toggle, secondary or tertiary valve.
EFD® TT User's Guide Version 1.2 4.3 HEIGHT SENSOR Each EFD® TT system is equipped with a standard tactile height sensor. The height sensor allows the Operator to activate the dispense gap function in a dot/line parameter. There are six (6) adjustable parameters for the height sensor: Probe Down Delay: This is the delay, after the tactile probe is extended (with a height sense command in a program), and before the Z-head starts to move. Unit is in seconds and the default is 0.25 seconds.
EFD® TT User's Guide Version 1.2 4.4 PARK LOCATION The park location is the position you want the dispense tip to move to after it has completed its taught program. This location is often a position closer to the work-piece than mechanical home in order to shorten the work cycle and also allows ample space for the part to be removed from the fixture plate. The default park location is set to mechanical home position which is X=0,Y=0, Z=0. This is indicated in the drop-down box as Home.
EFD® TT User's Guide Version 1.2 4.6 PURGE TOGGLE This screen performs the same function as in Section 4.5, except it is for the Toggle Valve instead of Valve #1. This purge routine can be accessed through the front panel LCD in program 98. From time to time, you may want to run the purge routine from the PDA. This can be accomplished by selecting “Util” in the Program mode then select “Purge Main” or “Purge Toggle” from the drop-down menu. 4.
EFD® TT User's Guide Version 1.2 5. PROGRAMMING 5.1 CREATING A NEW PROGRAM Before you start this exercise, print out the form called “Teaching Template” in Appendix B of this guide. 1.

Tap “OK” and select Arc from the Point Type drop-down menu. Tap “Teach CP” to save this point. 6.
EFD® TT User's Guide Version 1.2 5.4.4 IRREGULAR CONTINUOUS PATH Teaching irregular shapes requires the software to tie different elements together in a way that the taught path can be maneuvered in a smooth manner at a constant velocity. Short moves at sharp angles will limit the speed paths that can be run and should be avoided. Note: You can only incorporate lines and arcs elements in an irregular continuous path if it is strictly 2-dimensional.
EFD® TT User's Guide Version 1.2 1. From the main Program window, locate the instruction line where you want to insert a height sense command. 2. Tap “Insert”. This will open the Select Instruction window. 3. Select Height Sense, then press “OK”. The Z-axis will go to Safe Z position or Z=0 (if there is no Safe Z specified), and advance the probe. 4. Jog the probe to the location desired to take the height sense. This location should be as close to the dispense location as possible.
EFD® TT User's Guide Version 1.2 5.6 STEPPING AND REPEATING (REGULAR INTERVALS) The step and repeat function is very useful when there are several similar parts on a fixture. Once a pattern or points have been taught for one part, you can now step and repeat the pattern or points for the rest. row end origin program The origin is an important element in a step-and-repeat routine. In the example to the left, the origin is used as the reference point to step and repeat the 4-dot pattern in the 3X2 matrix.
EFD® TT User's Guide Version 1.2 2. To apply Step and Repeat to the entire program, select On. 3. Enter the number of rows and columns corresponding to the parts on the fixture. Select either traversing via row or column. Check the Serpentine box if desired. Corresponding to the above 4-dots example, we have taken 4 dots and program origin and stepped and repeated them in a 2X2 matrix. For a Y serpentine, you would select step and repeat on rows = 2, columns = 2, Traverse = Column, Serpentine = pi symbol.
EFD® TT User's Guide Version 1.2 2. Select Do Program and then tap “OK” to open the Do Program screen. 3. Select the name of program to insert from the Program drop-down menu. 4.

You can change the speeds by amending the values in the Preference setting within the PDA. Note that the jog settings will remain with that PDA even when connected to various machines. You can also choose to send the customized preferences to the machine.
EFD® TT User's Guide Version 1.2 A.2 Using the Keys on the Palm handheld In addition to the two methods stated above in the jog window, place the Palm handheld in a hard-key sensing mode to read input from the six hard keys on the Palm‘. These keys move the machine in only XY or Z. Diagonal jogging is not allowed in this mode. Note that jogging with the hard buttons is always available when the Palm‘ handheld is attached to the machine.

EFD® TT User's Guide Version 1.2 APPENDIX C Program Origin Program origin is the (0,0) coordinate for the program. All points in the program are relative to this location. i. Origin is the physical position that all moves are based upon. ii. The origin is used to allow for negative X/Y moves for needle offsets. iii. If home position is taught as origin, then negative moves cannot be accommodated for dispensing tip offsets. iv.
EFD® TT User's Guide Version 1.2 APPENDIX D Dot Parameters Explained Dot parameters control the different aspects of a dot dispense command. They need to be set prior to running a program. Although the program already has default settings, it is highly recommended that the User Operator review and set each Line Parameter to obtain the desired application results. Note: All time-related dot parameters are limited to a maximum of 65.535 seconds.
EFD® TT User's Guide Version 1.2 Multishot Delta This is the Z-height that the dispensing head will retract between each shot at the same X/Y location. It is used in conjunction with Number of Shots. Note that the Dwell Time parameter is applied between shots. The units are in inches or millimeters. In a potting application, the use of the Number of Shots and Multi-Shot Delta keep the dispense tip above the potting compound as part is being filled.
EFD® TT User's Guide Version 1.2 APPENDIX E Line Parameters Explained Line parameters control the different aspects of a line dispense command. They need to be set prior to teaching the end of a continuous path movement including the ARC and CIRCLE instructions. Although the program already has default settings, it is highly recommended that the User Operator review and set each Line Parameter to obtain the desired application results.
EFD® TT User's Guide Version 1.2 Dwell Time Dwell Time measures how long the dispensing head stays at the final position after the end of dispensing before retracting. This may be necessary to give the fluid a chance to detach from the tip and onto the substrate, i.e. increasing the Dwell Time can reduce “stringing” of material. The units are in seconds. Typically, 0 - 20 ms (0.020 sec) is sufficient. Reverse Time This parameter is only required when the 790 Auger Valve has been selected in the Setup mode.
EFD® TT User's Guide Version 1.2 Backtrack Length This is the horizontal distance the dispensing head moves back over the dispensed line after raising up the Backtrack Gap distance. This encourages congealed fluids to detach and distributes any excess fluid back across the line. The units are in inches or millimeters. Typically, 30 - 40 mils (0.030 - 0.040 in) is sufficient. Backtrack length can be negative.
