Notes for the paint change sequence:
The depicted paint change sequence represents the general principle and the
procedure for a complete paint change.
Detailed steps must must be individually adapted and optimized.
A possible signal exchange between the application controller and the powder
center for greater automation of the paint change sequence depends on the type of
application controller used.
The required intensity of the individual paint change steps and the possible repetition
of individual steps depends on the desired paint change intensity and how the powder
behaves.
If the PXM is connected to a nal lter, then the PXM throttle valves cannot be opened
when powder is introduced into the booth.
Otherwise, paint carryover may result from powder deposits in the booth/tubing.
It is generally recommended to run on loss for some time (e.g. 1 minute) after a paint
change and then switch to recovery.
When using powders with high amounts of pigment and wax, further measures may
be required, which must be speci ed individually.
WAGNER cannot make a forecast in this regard.
