Write Material Material Ready Ready Flag
Write Write Material Ready
The Write Material Ready Flag command is used to signal to the PD2K that the upstream material management has
the appropriate color/catalyst loaded at the inlet valve stack(s) of the pump(s) prior to a recipe change. This flag is
only used when multiple materials for a pump are fed to the PD2K via a single valve at the inlet valve stack (i.e. a
piggable system). See
NOTE: This flag should be cleared prior to or during a material change operation upstream of the inlet valve stack to
NOTE: NOTE:
avoid having the wrong material being fed into the pump during a recipe change.
Example: Setting the Material Ready Flag for Mix Unit #1.
