TARGET (left hand column) is the desired volumes of
Component A and Component B that the controller will
maintain.
ACTUAL (right hand column) shows the quantities of
Component A and Component B as they are being
dispensed.
FLOW is a real time display of how much flow is going
through the system. It updates every two seconds and is the
average of the last two flow rate displays. The flow rate
display can be altered in the setup program to read in
ounces. See the Display Units in cc or oz screens on page
21.
DESIRED RATIO is the display of what ratio the unit is
programmed to run at.
CURRENT RATIO is a display of what ratio the unit actually
dispensed on the last cycle.
Total volume of Component A (A=), Component B (B=), and
Component A + B (TOT VOL+) are displayed. The totalizers
are reset by pressing the RESET key or pressing the RPT
key. This screen can be altered in the setup program to read
in ounces. See the Display Units in cc or oz screens on
page 21.
To use total SOLVENT, you must have an optional flow
meter installed on the Precision Mix™ solvent inlet.
TIME TO IDLE is a 4 minute clock that counts down the time
that the spry device is not in use. After 4 minutes of not
triggering the spray device, the mix manifold closes and the
screen changes to the following System Idle screen.
When the spray device is triggered, the Precision Mix™ will
start again where it left off.
POT LIFE REMAINING displays how long the mixed fluid
has been sitting in the lines. If the unit is turned on and
nothing has been mixed, the pot life will not count down.
