Introduction 2-5
Front View Features
Below are short descriptions of the various parts and modules of the system (shown in Figure 2-1 through
Figure 2-3) and their functions. Detailed operational instructions for some of these features are treated in
other sections.
Computer System (computer, monitor, keyboard, mouse)
The Computer System is used to create and run dispensing programs with the Asymtek dispensing
software Fluidmove for Windows NT (FmNT).
Contact or Impingement Part Heaters
The C-721 dispensing system is factory-equipped with two independently or three configured substrate
heating stations, which provide complete thermal control during all phases of the dispensing process.
Heater temperature is controlled by the FmNT dispensing software. The two types of heaters, or tooling,
currently available for the C-721 system use either contact or impingement heating. Contact tooling
employs vacuum fixturing to hold the part to the heater. Impingement heat tooling uses positive air
pressure flowing through the unit to heat the part.
Control Panel
The Control Panel mainly uses membrane buttons. The Panel is organized to control certain
programming and run functions via three functional areas: Download Program Control, Motion Control,
and Safety Interlock Control. From the Panel you can move the Dispensing Head, move the conveyor
belts and rear rail, enable the Safety Interlock system, make an emergency stop, check dispensing status,
and adjust valve controls.
Conveyor
The specific type of conveyor installed in your system may be custom for your application. The standard
configuration for the Century C-721 is a SMEMA-compatible o-ring conveyor. The conveyor is
controlled via the Control Panel and through the Conveyor Controller Module and FmNT software.
Conveyor Controller Module
The Conveyor Controller module monitors the SMEMA interface and controls conveyor indexing
operations. All conveyors are SMEMA-compatible. The inputs and outputs are used for sensors, stop
pins, lift tables, and operation of the conveyor. For more information on the conveyor, see the Operation
section of this manual.
Dispensing Area
The Dispensing Area refers to the area in which dispensing operations are performed. The dimensions of
the Dispensing Area of your system will vary depending on the type and number of options installed
within it.
EMO button
In emergencies, this large, red “mushroom” button shuts down power to the Control Panel, the dispensing
mechanics, conveyor, and temperature controller. However, the EMO button does NOT shut down power
to the computer or the monitor.
Fluid Pressure Gauges and Regulators
The Fluid Pressure Gauges indicate how much air pressure is supplied to the syringes. The Fluid Pressure
Regulators are located underneath the front hood of the system. See the appropriate fluid pump manual
for the recommended setting for your pump.
