ORKS
Technology, microprocessor based, menu driven, ORP and conductivity
water treatment controller designed for use in cooling towers. The Model 3323 provides for ORP and
conductivity tracking and control, flow monitoring and chemical injection. The Model 3323 is CSA and
ANSI/UL approved.
The Model 3323 uses the latest in microprocessor capability, giving the user a high level of application
flexibility. A large illuminated graphics screen, multiple inputs, and an intuitive menu characterize this new
technology.
Security features allow full access to programming features or restrict access to viewing only. An operator
password can help ensure that only authorized personnel will operate the system.
The Model 3323 is user-friendly with a graphical screen and 16-key numeric keypad. It accepts multiple
inputs and is easily configured. This controller can easily be upgraded in the field. It‘s a combination of
reliability, accuracy, security and simplicity.

Technology gives you a high level of flexibility with the capability of adding nodes, additional
inputs and outputs, for monitoring and control. These nodes have functions such as extra relay outputs,
drum level inputs, pH inputs, conductivity inputs, ORP inputs, 4-20 mA inputs and water meter inputs.
Nodes are added using the
–NIN option, according to a mapped network. The mapped network shows the
full node addition capability of the LonWorks based 3300 series controllers.
The mapped network for the model 3323 shows that any or all of the following nodes can be added; two
relay nodes, two 4-20 mA input nodes, two digital input nodes, four remote sensor nodes (any combination
of pH, conductivity, or ORP), and one makeup conductivity node.
The complete mapped network is shown below
