Purge/Color Change Detail
Purge/Flush
The Purge Sequence flushes the lines from the A & B
color stacks though the mix manifold and out to the
gun(s).

If you choose a third flush option, it can be "A" or "B"
(not "A" and "B"). You do not have an option to select
something other than "A" or "B" valve. For example, if
"A" was water and "B" was solvent. The third flush
options would have to be "A" water or "B" solvent. You
couldn't assign a third option like air.

There are 4 basic purge sequences as follows:

A SPSA/SPSB alarm (Not enough volume during purge)
is generated when the end of a purge phase is reached
(Time specified by user), and the system has not totaled
at least 10cc of material.

Pre-Mix Fill
Premix fill sequence (right after purge sequence) loads
60 cc of the A1, A2, or A3 and B1, from the color stack,
to the mix manifold.

than 10 ccs in 60 seconds.

NOTE: Premix fill always starts with the “B” side.
Mix Fill
The mix fill sequence (right after premix fill) loads A1,
A2, or A3: B1 mixed material (Ratio specified by user)
out to the gun(s). It loads 110% of the volume of the
hoses plus the volume of the manifold: (hose 1 + hose 2
+ manifold) x 1.1

SM (mix fill low flow) is generated if there are less than
50ccs in 60 seconds during a mix fill sequence.
