TIP Adjusting the Z-axis velocity and acceleration can improve throughput by decreasing the amount of time it takes to make a height sense measurement.
Probe Adjustments for HS-Series To improve throughput and dispensing quality there are several adjustments you can make. You can adjust the probe height in relation to the needle height, you can adjust the distance between the probe tip and the needle tip, or you can adjust the up-and-down stroke length of the probe. Optimal adjustments may vary with the dispensing pattern, the substrate material, and the needle size. ? NOTE The DP-3000 Series pump requires a special Height Sensor probe.
To make large adjustments to the probe height: CAUTION! Only an Asymtek-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 (Figure 10-3). 4.

11 Needle Sensor The Needle Sensor can be installed at various locations around the dispensing area, depending on the model of dispensing system. Overview The C-721 is equipped with the NSZ Series Needle Sensor. The NSZ Needle Sensor includes an accessory Tactile Sensor used to calculate the Z-height of the needle tip during the machine offsets routine in Fluidmove for Windows NT (FmNT) (see Figures 11-1 and 11-2).
Theory of Operation The needle sensor gathers information about needle tip location by passing the needle in front of two light beams within the sensor, one for the X- and Z-axes, and one for the Y-axis. The NSZ Series needle sensor installed at the Asymtek factory is configured to work with the Fluidmove for Windows NT (FmNT) software.
Tactile Sensor The NSZ Series needle sensor uses an additional tactile sensor to determine an even more precise Z height. The Dispensing Head lowers and touches the needle tip to the Tactile Sensor, and then the needle tip height is reported to FmNT. Tactile Sensor Error 1. Gently lift the “hat” from the tactile sensor (Figure 11-2). 2. Use isopropyl alcohol and a soft cloth to remove any residual fluid from around the circumference of the “hat” and around the tactile sensor opening.

Dual-Action Setup using Fluidmove for Windows NT (FmNT) The Dual-Action Dispensing Head is installed at the Asymtek factory or at your facility by an Asymtek Field Service Engineer. FmNT software guides you through a one-time set up, which establishes the offsets between the fluid pumps and Z-axis heights for the Height Sensor probe, if installed.
Operation Controls You can adjust the speed of each fluid valve during dispensing operations. The fluid valve pressure and fluid syringe pressure are controlled by dispensing system regulators. You can also adjust the toggle speed for Valve 2 and the spacing between the fluid valves, but the spacing is set at the factory and should not need to be changed.
Adjusting Valve 2 Toggle Speed The airflow that controls Valve 2’s toggle speed (up and down movement) is set for your application at the Asymtek factory. If you need to readjust this toggle speed, follow the steps below. CAUTION! This procedure should be performed only by an Asymtek-trained service technician. A flathead screwdriver is the only tool needed for this operation. To adjust the toggle speed of Valve 2: 1.
External I/O The External I/O option for your Century Series system provides access to 24 I/Os. Century Series systems use 8-bit I/Os for normal operation of all system components. External I/O lets you add more accessories such as external devices or sensors. Connectors for External I/O ports A, B and C are located on the I/O Board, which is under the top cover of the dispenser at the corner of the Electronics Pan nearest the Light Beacon.
Operation Opto-I/O is electrically isolated from the other components of the system. This is an important safety feature for preventing overloads. The three 26-pin connectors are Ports A, B and C. Port A is the default port during normal operation and does not need to be connected to any device if it is the only active port. Ports B and C can be activated as accessories are added. Cables may be attached as needed.
9. 10. Select File from the menu bar. Select Save. Applicable ACL Commands I/O ports are controlled with the following commands. The ACL Reference Manual (P/N 76-CS02-01, Rev. 3.7 and later) details these capabilities.
Interconnects The following table of interconnects can be used for testing devices and I/Os. Normally, only trained service personnel use this table.
Hour Meter The Hour Meter, when installed in the system, measures the operation time of the dispensing system. Operation time is the total time, idle or operating, that the dispensing system is ON. The Hour Meter attaches to the rear of the system (Figure 13-4). 1 Item 1 Description Hour Meter Figure 13-4 Hour Meter The Hour Meter connects to the dispensing system Power Manager. When the dispensing system is turned ON, power is supplied to the Hour Meter and it begins counting.
Low Air Pressure Sensor The Low Air Pressure Sensor alerts the operator to pressure drops that can occur in large facilities that operate numerous pneumatic devices. The Sensor attaches to the P18 pneumatic outlet on the Pneumatics Module, which is located under the rear cowling. If facility air pressure drops below its assigned threshold, the Sensor triggers the Safety Interlock System, bringing dispenser movements to a halt.
Operation Controls Tool Required • Flathead screwdriver ? NOTE If you need to change the Main Air pressure, see “Main Air Inlet” in the Operation section. To set the low air pressure sensor set point: 1. Set the system pressure with the Valve Pressure or Fluid Pressure regulators to the low kPa (psi) at which you want to trigger the alarm. > See “Gauges and Regulators” in the Operation section for instructions on how to set pressure. 2. Slide the collar down on the Low Air Pressure Alarm sensor. 3.
Magnetic Fluid Level Sensor The magnetic fluid level sensor (Figure 13-7) monitors the fluid level inside a syringe. It connects to a special power cord labeled Fluid Level Sensor on the dispense head. The sensor is held by a bracket that attaches directly to the fluid cartridge. This fluid level sensor is available for 74 cc (2.5 fl oz) cartridges only.
Fluid Level Sensor Setup Hardware Setup The Fluid Level Sensor includes a mounting bracket that can either clip directly onto the fluid cartridge or to the valve bracket. On the back of the sensor is a screw that can be adjusted so that the sensor rests as close to the fluid cartridge as necessary. The power cord plugs into the Dispensing Head. Ensure that the magnet is properly installed on top of the follower, inside of the fluid cartridge.
14 Conveyors Overview Each Century Series inline dispensing system is equipped with a single-lane SMEMA-compatible o-ring conveyor. Typical conveyor configurations for systems with optional contact or impingement heaters are shown in Figure 14-1 and Figure 14-2. Your system conveyor configuration may vary depending upon application requirements.
2 1 Item 1 2 Description Part sensor Stop pin Figure 14-2 Typical Single-Lane Conveyor Configuration (impingement heaters) Theory of Operation This theory of operation is designed to include all of the basic features and functions of the conveyor on a typical Century Series C-721 dispensing system. All configurations have been taken into consideration. However, depending upon application requirements and system configuration, your specific operation may vary.
The part enters the dispense zone. Stop pins in the dispense zone block the conveyor path to stop the part. A lift table underneath the heating plate rises up to the part. Tooling on the conveyor rails hold the part in place during the dispensing process. The second part loaded into the pre-dispense zone. While dispensing is being performed on the first part in the dispense zone, a second part can enter the predispense zone. The part moves out of dispense zone.

15 Heaters Overview The C-721 dispensing system is factory-equipped with two or three independently configured substrate heating stations which provide complete thermal control during all phases of the dispensing process (a third heating station is optional). Part heater, or tooling temperature, is controlled by the Fluidmove for Windows NT (FmNT) dispensing software.
1 3 2 Item 1 2 3 Description Contact Heater Close-up of a Vacuum Port Vacuum Hole Figure 15-1 Contact Heater 15-2 Heaters
Impingement Heaters Impingement heat ensures precise and consistent substrate heating for reliable fluid dispensing when contact heating is not an option (Figure 15-2). Impingement heat tooling, or “impingement heaters” blow heated air at the bottom of the part, reducing the risk of damage to the substrate. Asymtek’s flexible impingement heat tooling features an adjustable board support that can be positioned to accommodate a wide variety of substrates.
Theory of Operation Both contact and impingement heaters work in accordance with the same theory of operation, giving the highest degree of thermal control during all phases of the dispensing process. Each type of heater is controlled by the FmNT dispensing software. In this theory of operation, all configurations are considered and included. However, your specific system operation with respect to underboard heaters and options may vary depending upon system configuration.

Impingement Heaters Impingement heater operation on the C-721 Series dispensing systems is similar to contact heater operation, with the exception of the vacuums, as described below and in steps A through D in Figure 15-4. Operation of the impingement heater blowers is constant, as described below and in steps E through G in Figure 15-3. For the heaters: A. Temperature parameters are set up in FmNT. B. FmNT sends the temperature information to the Temperature Controller Module. C.
Heater Setup There are no hardware setup procedures required for the heaters. The heaters are installed at the Asymtek factory prior to shipping and configured in FmNT according to your specific requirements. For general operation, it helps to know how your system heaters are configured. The following information is for reference and troubleshooting only.
Software Setup When your Century Series dispensing system is shipped from the Asymtek factory, it has specific heater files saved on the computer hard drive. These heater files have been programmed to fit your particular dispensing applications. They are attached to the dispensing programs for which they were created. If you wish to change these heater files or program new heater files, we strongly recommend that you first contact Asymtek Technical Support.
