Color Change Procedure
Refer to the Color Change Procedure included with your system manual for
instructions on color changing a powder coating system with a ColorMax
booth and this Encore Venturi Feed Center.
During a color change sequence, the lances are withdrawn from the powder
source, then lowered onto the purge manifold. High pressure air is directed
through the lances, pumps, feed hoses, and guns, purging them of powder.
The reclaim and virgin transfer pumps are also purged. The operator
cleans the sieve, lances, and the interior of the booth, and readies the feed
center for the next color. Meanwhile, another operator cleans the booth and
cyclone.
The recommended sequence of steps is provided in the color change charts
furnished by Nordson, but can be modified as desired depending on the
customer needs and requirements.
Shutdown
1. Move the system offline, if applicable.
2. Clean the system by performing the color change process, but do not
install a new powder source or turn the pumps, sieve, or vibratory table
on.
3. If you will be shutting down the powder feed center for maintenance,
repair, or an extended period of time, perform these steps:
d. Press the SYSTEM STOP button on the system control panel.
e. Turn the electrical disconnect switch on the powder feed center
control panel to the OFF position.
