Figure 3-22 Standard Gun Purge Configuration
Versa-Spray Nozzle Purge Configuration
This function uses high air pressure (typically line pressure) to blow powder
out of the gun nozzles. It can only be used with Versa-Spray guns equipped
with optional purge adapter kits and optional iControl console purge kits,
available in single or dual configurations. The purge kits must be
field-installed in the consoles. Purge kits are shipped with installation
instructions.
The settings on this screen are used for automatic purging. Set the nozzle
purge mode, Auto or Manual, from the Nozzle Purge Control screen
(Section 8, Operation), which also provides manual purge controls.
NOTE: Nozzle purge settings apply to all guns. They cannot be set or
controlled for individual guns or presets.
The purge settings work as follows: If the gap between the part being
sprayed and the next part is equal to or greater than the line gap setting,
then after the trailing edge of the part moves the purge delay distance,
nozzle purging is activated for the purge time.
Purging is terminated when the purge timer runs out, or a part enters the
gap area or spray zone, or when the operator turns off Auto purge by
selecting Manual from the Nozzle Purge Control screen.
