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.
Air Chop Time- duration of each activation of the air
purge valve during a chop sequence. User settable from
0.0-99.9 seconds.
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.
Chop Time- refers to the total length of the chop
sequence during a purge. User settable from 0-999 seconds.
Closed Loop Flow Control - refers to the process
when the flow rate is adjusted automatically to maintain
a constant flow.
Color/Catalyst Dump - refers to the time required to
flush the lines from the color or catalyst change module
to the mix manifold during a color or catalyst change.
Color/Catalyst Fill - refers to the time required to fill the
lines from the color or catalyst change module to the mix
manifold.
Coriolis Meter - a non-intrusive flow meter often used in
low flow applications or with light viscosity, shear sensitive,
or acid catalyzed materials. This meter uses vibration
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 transmit
communication signals.
Final Purge Source- source of the media used in the
final purge cycle. User settable to air purge valve, solvent
purge valve, or 3rd purge valve.
Final Purge Time- duration of the final purge cycle.
User settable from 0-999 seconds.
First Purge Source- source of the media used in the
first purge cycle. User settable to air purge valve, solvent
purge valve, or 3rd purge valve
First Purge Time- duration of the first purge cycle. User
settable from 0-999 seconds.
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 acceptable
variance that the system will allow before a flow
rate warning occurs.
Flow Set Point - a predefined flow rate target.
Flush Volume Check - system monitors flush volume.
E-11 Alarm occurs if minimum volume is not achieved.
Minimum flush volume is user settable (0-999 cc).
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 assurance
dose times and flow control processes.
Intrinsically Safe (IS) - refers to the ability to locate certain
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.
