Operations Flow Chart
A part enters the system from an upstream
location
Part is Conveyed to Pre-Dispense Zone
 Stop Pins are lowered to stop part transport.
 Clamp Bars or Lift Tables raise to hold the part in place.
 The underboard heaters turn on and the part is heated to a pre-
programmed temperature. The part remains at the pre-dispense

Part is Conveyed to Dispense Zone
 Stop Pins are lowered to stop part transport.
 Lift Tables/Clamp Bars are raised to hold the part in place during
the dispensing process.
 Another part is loaded into the Pre-dispense Station (optional).

indexed
Dispensing Preparations are Performed
 If required, the part is heated to a pre-programmed temperature
by Dispense Station underboard heaters.
 The Dispense Head moves to the Purge Station and the
Dispense Valve purges.
 If required, fluid may be heated by a Needle Heater (DV-7000 and
DP-3000 Valves) or a heater built into the Valve (DJ-2000).
