Theory of Operation
A. Dispense Head
1. Dispense Head movement is controlled by the programmable PMAC card which is
located inside of the computer.
2. The dispense heads moves in the XYZ planes.
 X, Y-Axis (Left, Right, Front, Rear)
 Z-Axis (Up, Down)
3. Home
 A reference point defined as (0, 0, 0,) in an X, Y, Z-axis coordinate system.
 The default home position is the extreme left front corner of the dispensing
area.
B. Conveyor
1. Depending upon application requirements and system configuration, the conveyor
setup may vary.
2. The conveyor atom is an Automove Control Language (ACL) file that contains the
software commands that control the conveyor.
 This file is downloaded to the 201 (W) Conveyor Controller Module, located in
the rear of the system, from the FmNT dispensing software.
 During system operation, FmNT uses this information to communicate with the
Conveyor Controller Module to coordinate part handling.
3. The following steps describe the basic theory of operation for the conveyor:
 Part is loaded into the pre-dispense zone.
 Part is heated.
 Timers are enabled.
 Part enters the dispense zone.
 Second part is loaded into the pre-dispense zone.
 Part moves out of the dispense zone.
 Part enters the post dispense zone.
C. Stop Pins/Clamp Bars/Lift Tables
1. Stop pins are pneumatic devices used to stop parts at each dispensing station.
2. The lift tables or clamp bars raise to hold the part in place when it is being
dispensed upon.
