CN9-SW is a graphic WINDOWSTM based software package designed
for PC supervision of up to 32 instruments, for remote adjustment,
configuration, cloning, saving and retrieving settings to files and
logging and charting in real time.
CN9-SW uses the MODBUS® protocol via either a fully isolated RS232
or RS485 link depending on the number of instruments and the
transmission distances involved in the application.
A users manual is supplied with the comms option. For more
information contact OMEGA. For details, see rear cover.
CN9400
It is suggested that users read the OVERVIEW section of this manual
before any installation or setting-up procedures are undertaken.
The CN9400 is a 1/16 DIN dual display, dual output miniature
controller with PID control strategy.
Note: The controller will not be operational until either the
QUICK-START or SET-UP procedure has been completed.
Control can be optimised with a single shot autotune either on
initial warm-up or at setpoint. The second setpoint can be
configured in a variety of alarm modes or PID Heat-Cool strategy. A
programmer offers a single ramp to setpoint with a choice of timed
soak period before switching off the output.
NB: Please note that in program mode, functions
are shown in the upper display (green) and options

Control of non temperature processes is achieved by the provision
of linear input ranges and scaling in commonly used engineering
units.

OVERVIEW
INSTALLATION
AUTOTUNE
To precisely control an application the controller will need to be
‘tuned’ using the built-in ‘AUTOTUNE’ feature. Autotune ‘teaches’
the controller the main characteristics of the process and ‘learns’ by
cycling the output on and off. The results are measured and used to
calculate optimum PID values which are automatically entered in the
controller memory.
The Model CN9400 controller is designed to be mounted in a 1/16
DIN panel cut-out. See the INSTALLATION section.
SET-UP
After installation the controller requires programming with the
following information:
During AUTOTUNE the optimum cycle-time is calculated but is not
automatically implemented. The cycle-time requires manual
acceptance unless pre-selected.
Type of Input Sensor
Operating unit (C or F etc)
Type of Output Device
Temperature Setpoint
To ensure good control over a wide range of applications two
versions of the Autotune program are provided, TUNE and TUNE AT
SETPOINT.
Note: The controller will not be operational until this
information is entered.
The TUNE method normally achieves the best results. Starting with
the load cool, tuning occurs during warm-up preventing overshoot.
This method of tuning is recommended.
When the above information has been programmed into the
controller it will be operational with the following factory PID
(proportional band, integral time, derivative time) settings.
Proportional band/Gain
Integral time/Reset
10°C/18°F
5 mins
20 secs
25 secs
1.5
The TUNE AT SETPOINT method is used for specialist applications.
eg. Heat-cool, multizones and processes below 100°C/200°F. During
the tuning cycle some overshoot occurs because the tuning cycle is
at set point.
Proportional cycle-time
Derivative time/Rate
DAC Derivative approach control
The DAC setting is not re-calculated.

Further information can be programmed into the controller, see
SECOND SETPOINT, RANGING AND SETPOINT LOCK, IMPROVING
CONTROL ACCURACY
CYCLE-TIME
The choice of cycle-time is influenced by the external switching
device or load. e.g. contactor, SSR, Valve. A setting that is too long
for the process will cause oscillation and a setting that is too short
will cause unnecessary wear to an electro-mechanical switching
device.
Functions and options
The facilities of the controller are selected from the multi-level menu
using the front panel mounted buttons.
Cycle-time selection methods
Note: It is advisable to study this section before any
The following methods of cycle-time selection may be used:
programming is undertaken.
Autotune calculated
Each level within the multi-level menu offers different functions, see
FUNCTIONS MENU for menu of main functions. Each function has a
range of user selections or options, see FUNCTION LIST for
functions and options details.
After Autotune has been run and completed the calculated cycle-
time can be manually accepted or adjusted to suit the switching
device. For selection method see Select Autotune Calculated
Cycle-time.
The controller has two modes, program mode and operating mode.
When in program mode the controller can be programmed with
settings and functions to suit the application. When in operating
mode the controller uses the setting and functions entered in the
program mode to control the application and also displays both the
process variable and setpoint temperatures. For full details on how
to program the controller see VIEWING AND SELECTING
FUNCTIONS.
Pre-select autotune cycle-time
The controller can be programmed to automatically accept the
calculated Autotune cycle-time. For selection method see Pre-
Select Automatic Acceptance of Any Autotune Cycle-time.
Pre-select before autotune
The controller can be programmed manually with any cycle-time
between 0.1 and 81 sec. This cycle-time will not be changed by any
Autotune functions. For selection method see Pre-Select Cycle-
time Before Autotune.
Note: In this manual the letter k is represented by the
character K
Factory set
To use the 20 sec factory set cycle-time no action is needed
whether Autotune is used or not.

ADVANCED SETTINGS
Before embarking on the Advanced Settings, please
familiarise yourself with the basic operation of the controller
as described in this manual. The following instructions
assume that the user understands how to make the initial
configuration, can navigate through the Function Menu and
successfully Autotune the controller in heating mode.

Heat-Cool strategy is a feature that improves control of processes
that need heating and cooling, depending on the conditions, for
example:
to At.SP
Environmental test chambers used in rooms where the
ambient temperature swings above and below the test
temperature.
Autotune will cause a temporary disturbance. Check that the
temperature has stabilised in heating mode before running the
process in cooling mode.
Plastics extruders where the material initially needs
heating, then cooling, when it begins to heat itself
exothermically due to pressure and friction applied by the
process.
If regular temperature oscillations occur, change CYC.t to optimum
value. See page 9. To select Autotune Calculated Cycle-time
Further adjustments – Cooling
The purpose of cool strategy is to maintain smooth control
of the process during transition from heating to cooling.
This is achieved by using PID control for heating and cooling with the
proportioning bands linked by an adjustable deadband.
Autotune uses the same calculated bAnd value for both SP1
(heating) and SP2 (cooling). In some processes, regular temperature
oscillations occur when cooling.
