Terminal
Block Description Non–Integrated Color Change Function I ntegrated Color Change Function
6051 Purge The Purge input is used to trigger a purge of the sys-
tem. The purge will be initiated after a 2 second delay.
Turning this input on and then off again will also reset
all active alarms. Same as Non–Integrated Color Change.
6061 Mix The Mix input is used to set the system into the mix
mode. The mix signal can remain high when an
Integrated Color Change is triggered. The
system will then perform the Integrated
Color Change and immediately go back
into the mix mode. If this is attempted
when color changing to recipe 0, an Invalid
Recipe alarm will occur because recipe 0
is not a valid recipe for mixing.
6071 Gun 1 Flow Control
Reset The Gun 1 Flow Control Reset input is used with hand
gun flow control operations. This signal will trigger the
system to try to maintain its setpoint if the current flow
rate is below the low limit setpoint. This signal is not
used for automatic gun flow control applications. Same as Non–Integrated Color Change.
6081 Gun 2 Flow Control
Reset The Gun 2 Flow Control Reset input is used with hand
gun flow control operations. This signal will trigger the
system to try to maintain its setpoint if the current flow
rate is below the low limit setpoint. This signal is not
used for automatic gun flow control applications. Same as Non–Integrated Color Change.
6091 Flow Control Override/
Maximum Analog The Flow Control/Maximum Analog Override input is
used when the system is being filled. This input will
cause the flow control fluid regulator to open so the
system can be quickly filled. This input is not needed
if the mixed load volume fill feature is used. The Flow Control/Maximum Analog Over-
ride input does not need to be used during
an Integrated Color Change. The system
will automatically open the fluid regulator
for purging and filling. This input will still
be needed, however, if a manual fill is at-
tempted while in the integrated color
change mode.
6111 Gun 1 Enabled This input is used to enable spray gun #1 use. Potlife
tracking and GFB operation by remote input. Same as Non–Integrated Color Change
6121 Gun 2 Enabled This input is used to enable spray gun #2 use. GFB
operation by remote select switch. Same as Non–Integrated Color Change
7051–7101 Recipe Bits (6 bits – 63
recipes) The Recipe Bit inputs are a binary representation of
the desired recipe for the PrecisonMix II 3K. When
these bits are changed the system will immediately
change to the new recipe. Example: Recipe 1 = Bit 0
high. Recipe 3 = Bit 0,1 high. Recipe 7 = Bit 0, 1,2
high. The Recipe Bit inputs work in conjunction
with the Color Change Input (5091) for In-
tegrated Color Change. The system will
automatically color change to a new recipe
if the Recipe Bits are changed and then
the Color Change bit is set high.
7121 Password The Password input is used to override the system
password set by the User Interface. If the system
password is forgotten or mistyped, this input allows the
user to temporarily bypass the security system. Same as Non–Integrated Color Change.
