20. Navigate to the Product Changeover page.
21. Select Unload Screen.
22. Select Stinger Dispenser. An extended menu is shown.
23. Select Purge Process. The camera axis drives to the centre of the board.
There are two process types for purging - Standard Purge Process and Auto-
matic Purge Process. The standard process provides the facility to dispense
material, directly onto the calibrated test product, for an indefinite amount of
time. This purges air pockets from the dispense head, or it is used to empty a
dispense head of material. The automatic process allows the purge to be
carried out at a purge station. The purge station also has a nozzle wipe facility.
The automatic purge process is used when a complete system purge is
required; either at the start or at the end of a production batch. As this process
requires a large volume of material to be purged, a purge station is used to
collect it.
Purge station consumable monitoring is turned on in Maintenance\Machine
Setup\Options\Stinger Options\Stinger Consumable Monitoring.
