Figure 3-23 Versa-Spray Nozzle Purge Configuration
To configure Nozzle Purging for Versa-Spray guns:
1. See Figure 3-23. Enable nozzle purging by touching the radio button
next to the check mark.
2. Set the purge time (0−30 seconds). Setting the time to zero disables
automatic mode, so that nozzle purging can only be done manually.
3. Set the purge delay (0−99 inches or 0−2515 millimeters). This is the
distance the trailing edge of the part must move past the spray guns
before nozzle purging is activated.
Use the purge delay setting with a restricted spray or perfect pickoff (0
or negative lag settings), where the coating could be ruined if purging
starts too soon.
With extended spray (positive lag setting), the part moves past the spray
guns before purging begins, so a delay may not be necessary.
4. Set the line gap (0−240 inches or 0−6096 millimeters). This is the
minimum distance you require between parts for nozzle purging.
Purging is only activated if the distance between the part being sprayed
and the next part is equal to or greater than line gap setting.
5. See Figure 3-24. Set the number of banks desired: 1, 2, or 4. This is
dependent on the number and type of purge kits you have installed in
your iControl consoles.
6. Assign guns to banks by touching the bank field for the gun. Touching
the field toggles the bank assignment on or off.
