Evacuation Purge Configuration
Evacuation purge can be used with all Sure Coat, Versa-Spray, and
Tribomatic guns.
NOTE: These settings apply to all guns. They cannot be set or controlled
for individual guns or presets.
Evacuation purge uses atomizing air or Tribomatic diffuser air to softly purge
the powder hose and gun (gun only for Tribomatic guns). This function
operates automatically for all guns when configured and enabled. It works
as follows:
S When the spray guns are triggered off the atomizing air flow changes to
the purge setting and flows until the purge timer expires.
S If the guns are triggered on for a new part before the timer expires,
purging immediately stops and the guns start spraying at the preset
settings.
NOTE: Do not use evacuation purge with Nordson In-Line powder pumps.
With these pumps the atomizing air used for purging pumps powder and
defeats the purge function.
To use evacuation purge:
1. Enable evacuation purge.
2. Set the purge timer (0−999 seconds).
3. Set the purge air flow (0.5−4.0 scfm).
