Fluid Pump
The fluid pump (also referred to as a “valve” or “jet”, depending on the type) dispenses the fluid onto the
part. It is mounted on the Dispensing Head, and holds the syringe of dispensing fluid. For more
information, see the appropriate fluid pump manual. Popular models include the DP-3000 Series Pump,
DV-6000 Series Pump, DV-7000 Series Heli-flow pump, and DJ-2100 Series DispenseJet valve.
Grounding Strap Connector
The operator’s grounding strap plugs into this connection to prevent Electrostatic Discharge (ESD).
Heat Station Timers
The heat station timers, located on the face of the 4- or 8-channel temperature controller, can be
programmed to pause a part in the pre-heat or post-heat zone for a specified amount of time. Generally
these timers are set up at the Asymtek factory. Parameters for checking setpoint temperatures prior to
dispensing are set through FmNT. See the Fluidmove for Windows NT User Guide for details.
Impingement Flow Controls, Two- or Three-Station
The impingement flow controls supply air directly and constantly to the impingement heaters.
Interlock Keyswitch
Activates or deactivates the Interlock Doors. For detailed information about the Interlock, see the Safety
section of this manual.
Levelers
The Levelers are adjusted during installation and should not need attention unless the system is moved to
a new location. To protect the dispensing system from moving during an earthquake, the levelers can be
anchored to the floor with screws.
Light Beacon
The Light Beacon is a warning device for the operator. The Light Beacon signals a dispensing status
condition by displaying a colored light and/or issuing an audible tone (Table 3-3).
Lower Front Cabinet
Contains the Computer, the 4- or 8-Channel Temperature Controller, Heat Station Timers, and the
Conveyor Controller Module.
Needle Sensor
The Needle Sensor records the XYZ position of the needle. The location information is sent to the FmNT
software.
Over-the-Board Fiber Optic Sensor
An Over-the-Board Fiber Optic Sensor, or part sensor, detects the presence of a board or carrier and
sends a message to the FmNT software. The information is transferred through the Conveyor Controller
Module to the system computer and used for SMEMA handshaking as parts move through the dispensing
system. Depending upon system configuration, there may be as many as three part sensors located along
the length of the rear conveyor rail.
Over-the-Board Sensor Amplifier
The Over-the-Board Sensor Amplifier works with the Over-the-Board Fiber Optic Sensor to detect the
presence of a board or carrier. Adjustments to the sensor system are made with the amplifier.
