Block Description Non–Integrated Color Change Function Integrated Color Change Function
5051 Gun Trigger 1 The Gun 1 Trigger input signals the PrecisionMix II 3K that
spraying with the first gun is being attempted. This input is
typically wired to an air flow switch that signals when at-
omization air is being sent to the gun. This input may also
be wired to a gun trigger signal from a robot to indicate
that material is being sprayed. Same as Non–Integrated Color
Change.
5061 Gun Trigger 2 The Gun 2 Trigger input signals the PrecisionMix II 3K that
spraying with the second gun is being attempted. This
input is typically wired to an air flow switch that signals
when atomization air is being sent to the gun. This input
may also be wired to a gun trigger signal from a robot to
indicate that material is being sprayed. Same as Non–Integrated Color
Change.
5071 External Alarm The External Alarm input allows an external device to shut
down the PrecisionMix II 3K system. If any operation is
taking place on the system, it will stop and the system will
go into standby. The alarm will be displayed on the User
Interface and on the Run Screen Monitor. It will also be
logged to the alarm history. Same as Non–Integrated Color
Change.
5081 Abort Reset The Abort Reset input will reset any active alarms in the
system. This input has the same function as moving the
operator switch from the standby to purge position to reset
alarms. Alarms such as the Potlife alarm and Purge Not
Complete Alarm will still require a full purge to be reset. Same as Non–Integrated Color
Change.
5091 Color Change The Color Change input indicates that a manual color
change is taking place. When this input is high, all totals
are accumulated under the “A + B + C Dump” category.
Setting the color change input high also prevents getting
Overdose Alarms during the dump of the A or B or C com-
ponent. The Color Change input will trigger an
integrated color change if it is kept high
for more than 0.2 seconds. The color
change will only occur if a new, valid
recipe has been selected by the recipe
input bits. This input will also trigger a
Queue color change when the system
is set on the Integrated Color Change
with Queue mode.
5101 Print Report The Print Report input will trigger the system to print a run
report. Printing a report will also trigger clearing of the job
totalizers. Same as Non–Integrated Color
Change.
5111 Purge/Load
Interlock #1 The Purge/Load Interlock #1 input is a safety interlock and
is required to be high before purging or loading with gun
#1 is allowed. This feature is typically used in conjunction
with Gun Flush Boxes and can be disabled by turning off
the Gun Flush Boxes on the configuration screens of the
User Interface. The Purge/Load Interlock #1 input
must also be set high before an Inte-
grated Color Change is allowed. This
safety interlock will still prevent purging
or loading manually and can be dis-
abled through the configuration
screens.
5121 Purge/Load
Interlock #2 The Purge/Load Interlock #2 input is a safety interlock and
is required to be high before purging or loading with gun
#2 is allowed. This feature is typically used in conjunction
with Gun Flush boxes and can be disabled by turning off
the Gun Flush Boxes on the configuration screens of the
User Interface. The Purge/Load Interlock #2 must also
be set high before an Integrated Color
Change is allowed. This safety inter-
lock will still prevent purging or loading
manually and can be disabled through
the configuration screen.
