Glossary of Terms
Overdose (A, B, C) Alarm - when either the resin (A),
or catalyst (B), or reducer (C) component dispenses too
much material and the system cannot compensate for
the additional material.
Potlife Time - the amount of time before a material
becomes unsprayable.
Potlife Volume - the amount of material that is required
to move through the mix manifold, hose and applicator
before the potlife timer is reset.
Purge - when all mixed material is flushed from the sys-
tem.
Purge Drive - The voltage drive during the Purge
sequence, maximum of 3300 mV. The response curve
of the V/P regulator is not linear, so it may be necessary
to test the response using Manual Override mode.
Purge Time - the amount of time required to flush all
mixed material from the system.
Purge Volume Alarm - E-11 Alarm occurs if minimum
flush volume is not achieved.
Ratio Tolerance - the settable percent of acceptable
variance that the system will allow before a ratio alarm
occurs.
Sequential Color Change - the process when a color
change is initiated and the system automatically flushes
the old color and loads a new color.
Sequential Dosing - Components A and B dispense
sequentially in the necessary volumes to attain the mix
ratio.
Solvent/3rd Purge Valve Chop Time- duration of each
activation of the solvent or 3rd purge valve during a
chop sequence. User settable from 0.0-99.9 seconds.
Solvent Fill - the time required to fill the mixed material
line with solvent.
Solvent Push - enables the user to save some mixed
material by pushing it out to the gun with solvent.
Requires an accessory solvent meter.
Standby - refers to the status of the system.
System Idle - This warning occurs if the ProMix is set to
Mix, and 2 minutes have elapsed since the system
received a flow meter pulse.
14
Third Purge Valve - refers to the use of three purge
valves used to flush some waterborne materials. The
valves are used to flush with water, air and solvent.
V/P - refers to the voltage to pressure device in the flow
control module.
Valve Holdoff Maximum - The maximum amount of
time that flow rate learning is not allowed after a dose
valve cycles. The system may internally use a time less
than is based on the stability of the fluid meter pulse
stream.
