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 gen-
eral description for the CN4321 controller. The second section will cover
the CN4431 controller, followed by a detailed description of the pro-
gramming parameters, which are common to both the controllers. Sev-
eral appendices describe some of the controlling techniques. Finally, a
Quick Reference guide gives a listing of all the parameters and their
default values.

SAFETY PRECAUTIONS
Before using this product, the user is requested to read the following
precautions carefully to ensure safety. The safety requirements are
classified as either “warning” or “caution” according to the following
explanations:
Warning
Wiring
1. If there is danger of serious accident resulting from a failure or
defect in this unit, provide the unit with an appropriate external pro-
tective circuit to prevent an accident.
2. The unit is normally supplied without a power switch or a fuse. Use
power switch and fuse as required (Rating of the fuse: 250V, 1A)
Power supply
1. Be sure to use the rated power supply voltage to protect the unit
against damage and to prevent failure.
2. Keep the power off until all of the wiring is completed so that electric
shock and trouble with the unit can be prevented.
General
1. Never attempt to disassemble, modify, or repair this unit. Tampering
with the unit may result in malfunction, electric shock, or fire.
2. Do not use the unit in combustible or explosive gaseous atmos-
pheres.
5
Caution
Installation
1. Avoid installing the unit in places where:
• the ambient temperature may reach beyond the range of -10 to 50°C
(14 to 122°F) while in operation
• the ambient humidity may reach higher than 90% RH while in
operation
• a change in the ambient temperature is so rapid as to cause
condensation
• corrosive gases (sulfide and ammonia gas, in particular) or
combustible gases are emitted
• the unit is subject to vibration or shock
• the unit is likely to come in contact with water, oil, chemicals, steam,
or vapor
• the unit is exposed to dust, salt, or air containing iron particles
• the unit is subject to interference with static electricity, magnetism,
or noise
• the unit is exposed to direct sunlight
• heat may be accumulated due to the radiation of heat
Maintenance
1. Do not use organic solvents such as alcohol or benzene to wipe this
unit. Use a neutral detergent.
UNPACKING
Remove the Packing List and verify that you have received all equipment,
including the following (quantities in parenthesis):
• Process controller (1)
• Mounting bracket (1)
• Socket with CN4431 (1)
• Operator’s manual (1)
• Waterproof gasket (1)
• 250Ωprecision resistor (when required) (1)
• Current transformer (when required) (1)
If you have any questions about the shipment, please call the OMEGA®Cus-
tomer Service Department.
When you receive the shipment, inspect the container and equipment for signs
of damage. Note any evidence of rough handling in transit. Immediately report
any damage to the shipping agent.
Note:
The carrier will not honor damage claims unless all shipping materials are
saved for inspection. After examining and removing contents, save packing
material and carton in the event reshipment is necessary.
