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.

To maximize your dispensing area, the space between Valve 1 and Valve 2 is set up for your application at the Asymtek factory. Depending on your fluid valves and accessories, you can separate the valves 100 mm (3.72 in) or 87 mm (3.42 in).

See Figure 13-3. 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.

This procedure should be performed only by an Asymtek-trained service technician. 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.

To reset Port assignment to Port A, or to use Ports B or C, enter an ACL command in FmNT to activate that port. ACL commands can be entered in Terminal Mode or added to the dispensing program. This procedure should be performed only by Asymtek-trained personnel. To change a port: Start FmNT.

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. Table 13-1 ACL Commands for Port Control Action Command Assign Port Change Outputs.

Interconnects The following table of interconnects can be used for testing devices and I/Os. Normally, only trained service personnel use this table. Table 13-2 Interconnects Signal Port A Pin# Port B Pin# Port C Pin# Input #0 Input #1 Input #2 Input #3 Input #4 Input #5. 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). Item Description Hour Meter. 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 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: 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. 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 on the dispense head.

The sensor is held by a bracket that Fluid Level Sensor attaches directly to the fluid cartridge. 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. 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. Operation When your system was installed by an Asymtek service engineer, part of the installation procedure included the downloading of a conveyor atom. The conveyor atom is an Automove Control Language (ACL) file that contains the software commands that control your conveyor. This file is downloaded to the 201 (W) Conveyor Controller Module, located in the rear of your system, from the Fluidmove for Windows NT (FmNT) dispensing software. Move the conveyor rail forward and backwards. If it does not respond, see Table 14-1. Check the conveyor belt for cracks or splits.

Notify an Asymtek service technician immediately if you notice a cracked or broken belt. Use an air gun or air blower attachment to remove any dust or debris that may have settled on the conveyor rails and belts. Test Window. If either the Left Right Sense I/O does turn ON, the sensor is functioning. If both the fail to turn ON, the sensor is not functioning.
