INTRODUCTION
The OMEGA®CN4321 and CN4431 controllers are economical process controllers that accept temperature or process inputs, and have sophisticated control capabilities, providing on/off control, PID, or autotune PID, with Fuzzy Logic. They feature an 8-segment ramp/soak function.
The CN4431 is a 1/16 DIN controller that has dual digital display for simultaneous indication of process value and setpoint. It is available with a single output that includes mechanical relay, 24V DC SSR driver, or 4-20 mA output. Options available include alarms (configurable as high/low, deviation, or zone alarm).
The CN4321 is a 1/32 DIN controller that has a single digital display. It is available with either single or dual outputs; dual output models can be used for heat/cool, heat/heat or cool/cool control. Output options include mechanical relay and 5V DC SSR driver. It also has an optional programmable alarm output.
The first section of this manual details the specifications and gen­eral description for the CN4321 controller. The second section will cover the CN4431 controller, followed by a detailed description of the pro­gramming parameters, which are common to both the controllers. Sev­eral appendices describe some of the controlling techniques. Finally, a Quick Reference guide gives a listing of all the parameters and their default values.

FRONT PANEL OPERATION
The programming menu consists of three blocks— SETUP MENU, SYSTEM MENU, and FACTORY PRESET MENU. At power up the controller will be in the operational mode– process variable (PV) will be displayed. This is the variable that is being controlled, and it is not programmable. When setting the parameters, turn off the power to the load (operating equipment) to ensure safety. Allow 30 minutes for the unit to stabilize in terms of temperature, and to achieve the rated accuracy. Option-related features are displayed only when the options are provided.
