ProMix 2KS Integration Specifics

Discrete I/O vs Network
Communications
The ProMix 2KS Automatic system does not use a
Booth Control. Instead, it uses Discrete I/O or Network
Communications to drive the system. Each method can
be used exclusively, or both at the same time.
In Automatic mode, the following fields can be set to
"Discrete" or "Network" (see Configure Screen 6 on
page 35):
• Flow Control
• Proportioning
• Gun 1 Trigger
NOTE: In Semi-automatic mode, only the Proportioning
field is available,
NOTE: The Manual Override function enables you to
operate the system before the automation (PLC) is
available. Manual Override still requires some communi-
cation through Discrete I/O or Network Communica-
tions. Although Manual Override is not intended to be
the main mode of control, it can be used if proper Gun
Trigger Input is provided.

Discrete I/O

Discrete I/O requires a 24 Vdc power supply which must
be supplied on site. The ProMix 2KS does not supply
power for Discrete I/O.
See Table 4 on page 54, F
8 on page 64 for inputs and outputs. Understanding
these inputs and outputs is necessary to properly inte-
grate the ProMix 2KS to the automation.
Input and output connections are made at the Discrete
I/O terminal strips (F . 63) and the discrete I/O board
IG
(F . 64) inside the EasyKey. Also see the System
IG
Electrical Schematic on page 128.
Review the Color Change Charts (F
full understanding of the color change sequence is nec-
essary to properly drive the inputs and monitor the out-
puts.
See Advanced Setup Screen 7, page 42. This screen
shows the actual status of all inputs and outputs. It is
important to ensure that each input from local automa-
tion (PLC) is received by the EasyKey and to verify that
the ProMix 2KS is sending outputs to the automation.
The following paragraphs describe each discrete I/O
function in detail.
