Conveyor Features Following are short descriptions of the conveyor’s key features (See Figure 4-7 and Figure 4-8). Adjustable Board Clamps Used with Bar Clamps to hold the board in place while dispensing. During initial process setup, these clamps can be slid along the Conveyor rail to position them over the board. Bar Clamps When the part stops in the dispense zone, a Bar Clamp on each conveyor rail rises to immobilize the part for dispensing.
Conveyor Adjustments The conveyor should not need adjustments during normal operation. However, when programming or changing parts, you may need to move the part to the left or right, or change the width of the conveyor rails. Follow the procedures below. To move the conveyor belts left or right: 1. Press CONVEYOR on the Control Panel (see Table 4-4). > The conveyor LED blinks when CONVEYOR control is active. 2. Press the left or right arrow to move the belts in that direction.
Gauges and Regulators The C-718SMT has four types of gauges and regulators: • Main Air • Fluid • Valve • Conveyor WARNING! To reach inside the Century Series system front doors or through the light curtain, you must fully understand the related Safety Interlock and DISPENSER STATUS indicators (see Table 4-6 and Table 4-8). The fluid and valve regulator controls are black knobs extending down from the roof of the dispensing area.
Main Air Inlet Located next to the air filter, the Main Air Inlet provides regulated air pressure to the dispensing system from your facility air source. You can adjust the main air pressure with the metal T-bar regulator (see Figure 4-9 and following below). The recommended pressure from the facility air supply to the dispensing system is 586–620 kPa (85–90 psi).
Fluid and Valve Fittings The pneumatic fittings for the fluid and valve pressure are located on the right side of the dispensing head (see Figure 4-10).
Black Blue 5 15 10 Clear c Ta tile He igh tS en so r Operation VALVE 1 VALVE 2 Figure 4-10 Fluid and Valve Pneumatic Fittings (Connections shown for DJ-2000) 4-27
Fluid Pressure The fluid pressure regulator controls the flow of air from the Main Air Inlet to the clear pneumatic fitting located on the right side of the dispensing head. This fitting connects to the top of the syringe. The system maintains steady fluid flow by applying air at a constant pressure to the syringe while the dispensing system is ON. For more details on how the air is used for fluid pump or valve operation, see the manual for your specific fluid pump.
Valve Pressure Depending on your application, valve pressure controls the flow of air from the Main Air Inlet through the air line that connects to the fluid pump (see Table 4-9). Air pressure pushes the fluid pump open and closed during dispensing. Your dispensing program controls the pressure to operate the fluid pump while dispensing fluid. For more details on how the air is used for fluid pump operation, see the appropriate manual for your specific fluid pump.
To adjust the fluid pressure / valve pressure: 1. Verify that the dispensing system is ON. > The System Status LED and Light Beacon should be yellow or green. 2. Open the front doors. > The green System Status LED and Light Beacon will turn yellow. 3. Reach underneath the left side of the front hood of the dispensing system and pull the fluid pressure regulator down to unlock it. 4. Rotate the regulator counter-clockwise to set the fluid pressure to 0 kPa (0 psi). 5.
Conveyor Air Located on the rear of the dispensing system (see Figure 4-9), the Conveyor Air gauge and regulator controls air pressure that moves the conveyor’s stop pins, bar clamps, and Under Board Support (option). The recommended conveyor air pressure is 3.86 kg/cm2 (55 psi). ? NOTE If air pressure is too high, you can damage parts. If pressure is too low, the stop pins, bar clamps, and under board support (option) will not work.
List of Consumables The following items represent operational support material required for operating the C-718SMT system. They are considered consumables and are to be discarded after use.
5 Startup/Shutdown This section describes how to startup and shutdown the C-718SMT for production, programming, or service. This procedure is a general recommendation—your actual startup and shutdown procedure may vary. See your own documentation, if available. The following procedure assumes that an Asymtek technician has already installed your system and that all power cables are connected to the facility AC power source.
Production Startup The following procedure describes how an operator runs a dispensing program with a clean fluid pump and/or a new syringe. The procedure assumes that the pump and syringe have been installed on the dispensing head, and that a dispensing program has been created (using either FmNT or CAD Import) and saved on the computer hard drive.

9 Vision System Overview Asymtek offers a choice of two vision systems for many of its dispensing systems. The AV700 Targeting Offset Camera is the basic vision system provided with the standard configuration. The AV-2550 Pattern Recognition System (PRS) is an advanced vision system with a choice of light sources to accommodate edge detection and fiducial detection. Both vision systems are compatible with the Asymtek dispensing software, Fluidmove for Windows NT (FmNT).
AV-700 Targeting Offset Camera The AV-700 displays a magnified video image of your workpiece on the computer monitor while you are running Fluidmove software. When you program using the AV-700, the camera video overlays a crosshairs on the image to let you locate XY coordinates for accurate dispensing pattern placement. The AV-700 operates in Download Mode or with FmNT.
Operation When the dispensing system is ON, the light ring illuminates and the camera turns ON. The camera magnifies the workpiece image and sends it to the system computer. The light ring card inside the computer supplies the camera with power. It also receives the camera signal and sends it to the video card. The video card displays an image on the computer monitor with a crosshair overlay. The crosshair is calibrated to the XY location using a Fluidmove setup routine.
Operation Controls To operate the AV-700 while programming in FmNT: 1. In the FmNT Main Window, click on Teach a Program. 2. The video display activates automatically when programming a dispensing command. > You can also activate the video display by clicking on the camera icon. 3. Follow the on-screen prompts and consult the On-line Help, if necessary.
Adjustments for the AV-700 The built-in light ring and camera on the AV-700 may require adjustments to the brightness and focus. To adjust the brightness of the video display: 1. Locate the f-stop ring on the camera lens (see Figure 9-2). It has the numbers 1.6, 2, 4, 8 and 16 on it. These are different aperture sizes, which control brightness. 2. Twist the f-stop ring to the desired brightness. > To increase the brightness, twist it to a larger aperture.
Minor Troubleshooting There are some troubleshooting procedures that an operator may perform. These are listed in Table 9-2. Some symptoms that appear to be problems with the vision system may actually have other causes. Refer unsolved problems to a service technician. Table 9-2 AV-700 Troubleshooting Symptom No image Unfocused image 9-6 Check/Correction • Make sure that the lens cap has been removed from the camera. • Check the camera cable harness connection at the back of the dispensing head.

AV-2550 Pattern Recognition System The AV-2550 Pattern Recognition System (PRS) magnifies the workpiece and displays it on the computer monitor. The AV-2550 has a vision processor in addition to all of the same hardware as the AV-700 described above. This vision processor can recognize certain shapes, called fiducials, on the part or substrate and can be “taught” to recognize them on other parts for quick, accurate pattern placement.
Operation The sections below are an overview of the hardware operation of the AV-2550 system. See Figure 9-4 to locate parts. Theory of Operation The camera turns ON, the image is processed through the vision processor and is displayed on the monitor. The camera generates a crosshair over the image. The crosshair is calibrated to the XY location using a Fluidmove setup routine. After calibration, the dispensing head, camera and light source are moved to a fiducial location on a workpiece.
Adjustments for the AV-2550 In FmNT see On-line Help for controlling these features. Minor Troubleshooting Operator-performed troubleshooting procedures are listed in Table 9-4. Some symptoms that appear to be problems with the vision system may actually have other causes. Refer unsolved problems to a service technician.

10 Height Sensor Overview The Retractable Adjustable Height Sensor is located on the dispensing head next to the needle or nozzle. It checks and gauges substrate height to help maintain consistent dispensing height on a non-level or warped substrate. Consistent dispensing height is essential to ensure consistent dispensing quality. If your system includes this option, it should have been installed at the Asymtek factory prior to shipping.
Installation See Figure 10-2 to locate parts. Tools and Materials Needed • Height Sensor • Philips head screwdriver CAUTION! Only a trained service technician should perform this procedure. To install the Height Sensor: 1. Determine the type of valve or fluid pump installed on your dispensing system. ? NOTE ? DV-6000 pumps, DP Series pumps, and the DJ-2000 DispenseJet® attach directly to the valve bracket (see Figure 10-2). Go to Step 3.

Setup Before performing any dispensing programs with the Height Sensor, make sure that the Height Sensor is properly set up. To set up the Height Sensor, follow the instructions below. Hardware Setup Once you have installed your Height Sensor, perform the following hardware setup procedure to verify that the Height Sensor is in a neutral position before making any probe adjustments or performing the software setup procedure.
Software Setup During the software setup process, you can assign values to control various Height Sensor parameters. In FmNT you can control: • Up and Down Speed and Acceleration of the dispensing head during a height sense • Maximum Search Depth that the dispensing head will descend in search of the substrate • Retract Distance after a height sense TIP Make sure that your Height Sensor is properly set up prior to programming. To set up the Height Sensor in FmNT: 1.
Probe Adjustments To accommodate the dispensing pattern, the substrate material, and/or the needle size, you may need to adjust the probe height in relation to the needle height, or adjust the distance between the probe tip and the needle tip. These adjustments can improve throughput and dispensing quality. Height Sensor CAUTION! Consult a service technician before performing any of these adjustments.
Probe Height Adjustments An operator can make small-scale adjustments to probe height using the micrometer adjustment. Only a service technician should make large-scale adjustments to probe height. Service technicians can also adjust the Z-Axis velocity and acceleration. The Z-Axis velocity and acceleration values are applied to the dispense head during a height sense and can increase throughput. See the specifications on page 10-14 for more information.
To make large-scale adjustments to the probe tip height and position: CAUTION! Only a trained service technician should perform this procedure. 1. Raise the dispensing head so that neither the needle tip nor the probe tip is touching the work surface. 2. Make sure the probe is in the gear down (GD) position. 3. Using the 1/16-inch hex key, loosen the probe set screw accessed through the hole on the right side of the Height Sensor (see Figure 10-1). 4.
Probe Removal and Replacement Use the following procedure to remove and replace the Height Sensor probe. CAUTION! If your system is equipped with a DP-3000, you may need to upgrade the Height Sensor probe. A special probe is required for the DP-3000 dispensing valve. If you need to change that probe, contact Technical Support and ask for the DP-3000 probe replacement kit. Tools and Materials Needed • 1/16-inch hex key To remove and replace the Height Sensor probe: 1. Remove the Height Sensor. 2.
Z-Axis Velocity and Acceleration The Z-Axis velocity and acceleration control the speed and acceleration of the lowering and raising of the dispensing head during a height sense measurement. Adjusting the Z-Axis velocity and acceleration can improve throughput by decreasing the time for a height sense measurement. ? NOTE At the factory, Z-Axis velocity is set at 2 in. per second, and Z-Axis acceleration is set at 300 in. per second. To adjust the Z-Axis velocity and acceleration in FmNT: 1.
Operation Height Sensor operation is controlled by Setup selections in FmNT. You can also insert more height sense commands directly into dispensing programs. When not measuring height, the Height Sensor probe remains retracted, preventing it from interfering with the dispensing process. Theory of Operation The Height Sensor uses a stainless steel probe to contact the dispensing surface. The probe tip is machined to minimize surface contact. Approximately 5 grams (0.

11 Needle Sensor Overview The Needle Sensor can be installed at various locations around the dispensing area, depending on the model of dispensing system. There are two types of Needle Sensors currently available: the NS Series and the NSZ Series. M-2000, Millennium Series and Century Series dispensing systems with FmNT can use either type of Needle Sensor.
Markings for Height Sensor and Needle Calibration Needle Sensor LED (Green) Needle Slot or ns Se e dl ies ee er N -S S N Figure 11-2 NS Series Needle Sensor The NSZ Series Needle Sensor includes a Load Cell, which is used to calculate the Zheight of the needle tip during the Valve Offsets routine in Fluidmove. The Load Cell also determines the offset between the needle tip and the height sensor probe tip.
Setup Your system’s Needle Sensor is installed at the factory, and Fluidmove is configured to work with the specific Sensor. If you make significant changes to your system configuration, upgrade your Fluidmove software, or if you are having trouble with the Valve Offsets or Calculate Master Offsets routines, you will need to perform the setup procedures below. Setup in FmNT Fluidmove has two routines for Needle Sensor operation--Valve Offsets and Calculate Master Offsets.
Operation Both the NS Series Needle Sensor and the NSZ Series Needle Sensor work with FmNT. The software on the dispensing system is configured at the Asymtek factory to work with either type of Needle Sensor. Theory of Operation The dispensing head lowers the dispensing needle into the Sensor’s needle slot, then passes it in front of two light beams, one for the X-Axis and one for the Y-Axis. When the needle breaks a beam, a coordinate is recorded.
Minor Troubleshooting Table 11-1 Symptom LED does not come ON during routine. Needle Sensor Troubleshooting Possible Cause • Needle Sensor malfunction. • No power to Needle Sensor. Recovery Call a service technician. LED is constantly ON. Something blocking the sensor. Clean sensor slots with a soft cloth or by blowing air through them.
