Glossary of Terms
Air Chop - the process of mixing air and solvent
together during the flush cycle to help clean the lines
and reduce solvent usage.
Analog - relating to, or being a device in which data are
represented by continuously variable, measurable,
physical quantities, such as length, width, voltage, or
pressure.
Closed Loop Flow Control - refers to the process
when the flow rate is adjusted automatically to maintain
a constant flow.
Coriolis Meter - a non-intrusive flow meter often used in
low flow applications or with light viscosity, shear sensi-
tive, or acid catalyzed materials. This meter uses vibra-
tion to measure flow.
Digital Input and Output - a description of data which
is transmitted as a sequence of discrete symbols, most
commonly this means binary data represented using
electronic or electromagnetic signals.
Discrete I/O - refers to data that constitutes a separate
entity and has direct communication to another control.
Dose Size - the amount of resin (A) and catalyst (B) that
is dispensed into an integrator.
Dose Time Alarm - the amount of time that is allowed
for a dose to occur before an alarm occurs.
Dynamic Dosing - Component A dispenses constantly.
Component B dispenses intermittently in the necessary
volume to attain the mix ratio.
Ethernet - a method for directly connecting a computer
to a network or equipment in the same physical location.
Fiber Optic Communication - the use of light to trans-
mit communication signals.

Fill Time - the amount of time that is required to load
mix material to the applicator.
Flow Control Resolution - a settable value that allows
the flow control system to maximize its performance.
The value is based on maximum desired flow rates.
Flow Rate Analog Signal - the type of communication
signal that can be used on the ProControl module.
Flow Rate Tolerance - the settable percent of accept-
able variance that the system will allow before a flow
rate warning occurs.
Flow Set Point - a predefined flow rate target.
Grand Total - a non-resettable value that shows the
total amount of material dispensed through the system.
Gun Trigger Input Signal - used to manage ratio assur-
ance dose times and flow control processes.
Intrinsically Safe (IS) - refers to the ability to locate cer-
tain components in a hazardous location.
Idle - if the gun is not triggered for 2 minutes the system
enters Idle mode. Trigger the gun to resume operation.
Job Total - a resettable value that shows the amount of
material dispensed through the system for one job. A job
is complete when a color change or complete system
flush occurs.
K-factor - a value that refers to the amount of material
that passes through a meter. The assigned value refers
to an amount of material per pulse.
Ki - refers to the degree fluid flow over shoots its set
point.
Kp - refers to the speed in which the fluid flow reaches
its set point.
