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).
"A" has a pre-assigned (not selectable) valve. "B" has a
pre-assigned (not selectable) valve.
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.
The following should be the only selectable flush
sequence options:
There are 4 basic purge sequences as follows:
1. Selecting the purge button on the pendant. The
purge sequence from the recipe that you are cur-
rently in is used. The system is left full of solvent.
2. Color Change from A1, A2 or A3 to A1, A2 or A3.
The purge sequence from the recipe you are leaving
is used. After the purge sequence completes, the
premix fill, from the recipe that you are going to,
starts (blinking recipe number, etc).
3. Color Change from A1, A2 or A3 to Zero. The recipe
zero purge sequence is used. The system is left full
of solvent.
4. Color change from Zero to Zero. The recipe zero
purge sequence is used. The system is left full of
solvent.
NOTE: Color Change from Zero to A1, A2 or A3. The
system does not do a purge sequence. It immediately
starts the premix fill sequence.
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.
In the premix fill sequence, a SFA1/SFA2/SFA3/SFB1
alarm (Premix fill, low flow) is generated if there are less
than 10 ccs in 60 seconds.
SHA1/SHA2/SHA3/SHB1 alarm (Not enough premix fill
volume) is generated if there are less than 50 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.
SN (Not enough mix fill volume) is generated if less than
the mix fill volume is loaded in 5 minutes during a mix fill
sequence.
