There are two process types for purging - Standard Purge Process and Automatic 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.
When the pot is full an action panel is displayed reminding the user to replenish the pot.
NOTE
In product changeover, where hardware has been replaced, the laser unit needs to be recalibrated.
It is advised to carry out the manual calibration of Stinger heights, see appendix, prior to performing
the automatic calibration.
