OPERATING MODES
The controller can be used in two modes:
Automatic mode - in which the output power is automatically adjusted to hold the
temperature at the required value. The controller normally operates in this mode.
Manual mode - in which the output is manually adjusted by the Operator. In this mode
the ‘MAN’ light will be on.
One other mode is available:
Remote setpoint - The setpoint is generated as an input signal from a master CN2216
series controller. In this mode the REM light is on.

INTRODUCTION
The model CN2216 is a precision temperature controller with self-tuning. It has a modular
hardware construction, which provides two control outputs, one alarm relay and one
communications port.
Controller labels
The labels on the sides of the controller identify the ordering code, the serial number, and
the wiring connections.
Appendix A, Understanding the Ordering Code explains the hardware and software
configuration of your particular controller.
MECHANICAL INSTALLATION
To install the controller
Cut the panel to the relevant hole size shown in Figure 2-2.
Insert the controller through the front of this cut-out.
Spring the upper and lower panel retaining clips into place. Secure the controller in
position by holding it level and pushing both retaining clips forward.
Note: If the panel retaining clips subsequently need removing, they can be unhooked from
the side with either your fingers or a screwdriver.
Unplugging and plugging-in the controller
The controller can be unplugged from its sleeve by easing the latching ears outwards and
pulling it forward out of the sleeve. When plugging the controller back into it’s sleeve,
ensure that the latching ears click into place to maintain the IP65 sealing.

Please read Appendix B, safety and EMC information before proceeding.
WARNING
Please ensure that the controller is correctly configured for your
application. Incorrect configuration could result in damage to the process
being controlled, and/or personal injury. The controller may either have
been configured when ordered, or may need configuring now. See Chapter

Wire Sizes
All electrical connections are made to the screw terminals at the rear of the controller. These
accept wire sizes from 0.5 to 1.5 mm
2
(16 to 22 AWG), and are protected by a hinged cover
to prevent hands or metal making accidental contact with live wires. Rear terminal screws
should be tightened to a torque of 0.4 Nm (3.5 lb. in).
Wiring connections
The wiring connections are shown above.
Outputs 1 and 2 are factory fitted modules, which can be any one of the types shown in

PDLINK modes
PDLINK is a proprietary technique for bi-directional communication over a single pair of
wires. There are several operating modes.
In mode 1 a dc pulse output delivers a power demand signal to a SSC-TE10S solid state
(SSR) relay and the SSR responds with a single load circuit failure message.
In mode 2 a dc pulse output delivers a power demand signal to a SSC-TE10S and the SSR
responds with the ON state rms load current, and two fault messages - SSR failure or heater
circuit failure.
Snubbers
The controller is supplied with ‘snubbers’ (15nF +100Ω) which should be wired across the
relay or triac outputs when switching inductive loads such as mechanical contactors and
solenoid valves. The snubbers are used to prolong contact life and to suppress interference
when switching such loads.
Snubbers pass 0.6mA at 110Vac and 1.2mA at 240Vac, which may be sufficient to hold in
high impedance relay coils. They should not, therefore, be used in such installations.
WARNING
When a relay contact is used in an alarm circuit ensure that the
current passing through the snubber when the relay contact is
open does not hold in low power electrical loads and thereby
interfere with the fail-safe operation of the alarm circuit.
COMMUNICATIONS CONNECTIONS
The communications option can either of two types shown in the table below

2-wire RS-485 (EIA-485) is a connection, which allows up to 32
controllers to be multi-dropped from a single communications link
over a distance of up to 1.2Km. To ensure reliable operation of
the communications link, (without data corruption due to noise or
line reflections) the connections between the controller should be
made using a twisted pair of wires inside a screened cable with the
connections terminated with resistors in the manner shown in this
diagram. This diagram also shows the use of a communications
isolator/converter to connect the RS-485 (EIA-485) link into a
standard RS-232 (EIA-232) computer port.

Installation and Operation HandbookAccess Levels
Chapter 3 ACCESS LEVELS
This chapter describes the different levels of access to the operating parameters within
the controller.
There are three topics:
• THE DIFFERENT ACCESS LEVELS
• SELECTING AN ACCESS LEVEL
• EDIT LEVEL
THE DIFFERENT ACCESS LEVELS
There are four access levels:
• Operator level, which you will normally use to operate the controller
• Configuration level, which is used to set up the fundamental characteristics of the
controller
•Full level, which is used to commission the controller and the process being
controlled

EDIT LEVEL
Edit level is used to set which parameters you can see and adjust in Operator level. It
also gives access to the ‘Promote’ feature which allows you to select and add (‘Promote’)
up to twelve parameters into the Home display list, thereby giving simple access to
commonly used parameters.
Setting operator access to a parameter
First you must select Edit level, as shown on the previous page.
Once in Edit level, you select a list or a parameter within a list in the same way as you
would in Operator or Full level. That is to say, you move from list header to list header
by pressing the Page button. And, from parameter to parameter within each list using the
Scroll button. However, in Edit level what is displayed is not the value of a selected
parameter but a code representing the parameter’s availability in Operator level.
When you have selected the required parameter, use the and buttons to set
its availability in operator level.
There are four codes:
ALtrALtrMakes a parameter alterable in Operator level
ProProPromotes a parameter into the Home display list
REAdREAdMakes a parameter or list header read-only (it can be viewed but not altered)
HidEHidEHides a parameter or list header.
For example:
2FSL
The parameter selected is the set point for
Alarm 2 - Full Scale Low
ALtr
Hiding or revealing a complete list
To hide a complete list of parameters, all you have to do is hide the list header. If a list
header is selected only two selections are available: REAd and HidE.
(It is not possible to hide the ‘ACCS’ list, which will always display the code: ‘LiSt’.)
Promoting a parameter
Scroll through the lists to the required parameter and choose the ‘Pro’ code. The
parameter is then automatically added(promoted) into the Home display list (the
parameter will also be accessible as normal from the standard lists. A maximum of
twelve parameters can be promoted. Promoted parameters are automatically ‘alterable’.

Chapter 4 TUNING
Before tuning please read Chapter 1, Operation, to learn how to select and change a
parameter.
This chapter has three main topics:
• WHAT IS TUNING?
• AUTOMATIC TUNING
• MANUAL TUNING
WHAT IS TUNING?
In tuning you match the characteristics of the controller to that of the process being
controlled in order to obtain good control. Good control means:
• Stable ‘straight-line’ control of the temperature at setpoint without fluctuation
• Acceptable overshoot or undershoot of the temperature setpoint
• Quick response to deviations from the setpoint caused by external disturbances,
thereby restoring the temperature rapidly to the setpoint value.
Tuning involves calculating and setting the value of the parameters listed in Table 4-1.
These parameters appear in the PID list.

The number of display units below setpoint at which the
controller will cutback the output power in order to prevent
overshoot on heat up.
The number of display units above setpoint at which the
controller will increase the output power in order to prevent
undershoot on cool down.
Only present if cooling has been configured. Sets the
cooling proportional band by dividing the Pb value by the
rEL value.
Page 36
Tuning Installation and Operation Handbook
AUTOMATIC TUNING
This method automatically determines the value of the parameters listed in table 4-1 on
the previous page.
The CN2216 uses a ‘one-shot’ tuner which works by switching the output on and off to
induce an oscillation in the measured value. From the amplitude and period of the
oscillation, it calculates the tuning parameter values.
If the process cannot tolerate full heating or cooling being applied during tuning, then the
level of heating or cooling can be restricted by setting the heating and cooling power
limits in the Output list. However, the measured value must oscillate to some degree for
the tuner to be able to calculate values
A One-shot Tune can be performed at any time but normally it is performed only once
during the initial commissioning of the process. However, if the process under control
subsequently becomes unstable (because its characteristics have changed), you can retune again for the new conditions.
It is best to start tuning with the process at ambient temperature. This allows the tuner to
calculate more accurately the low cutback and high cutback values that restrict the
amount of overshoot or undershoot.
Heating and Cooling Output Cycle Times
Before commencing a tuning cycle, set the values of CYC.H (heat cycle time) and CYC.C
(cool cycle time) in the oP (output) list. These values apply if you are using a dc pulse,
relay or AC SSR output. They have no effect on a DC output.
A dc pulse output switching a solid state relay should be set to 1 sec.
A relay or AC SSR output should be set to 20 sec.

Installation and Operation Handbook Tuning
How to tune
1. Set the setpoint to the value at which you will normally operate the process.
2. In the ‘Atun’ list, select ‘tunE’ and set it to ‘on’
3. Press the Page and Scroll buttons together to return to the Home display. The
display will flash ‘tunE’ to indicate that tuning is in progress.
4. The controller will induce an oscillation in the temperature by turning the
heating on and then off. The first cycle will not complete until the measured
value has reached the required setpoint.
5. After two cycles of oscillation the tuning will be completed and the tuner will
switch itself off.
6. The controller will then calculate the tuning parameters listed in Table 4-1 and
will resume normal control action.
If you want ‘Proportional only’ or ‘PD’ or ‘PI’ control, you should set the ‘ti’ or ‘td’
parameters to OFF before commencing the tuning cycle. The tuner will leave them off
and will not calculate a value for them.

Temperature

Time
Calculation of the cutback values
Low cutback and High cutback are values that restrict the amount of overshoot or
undershoot that occurs during large step changes in temperature (for example, under
start-up conditions).
If either low cutback or high cutback is set to ‘AUTOAUTO’ the values will be fixed at three
times the proportional band, and will not be changed during automatic tuning.
CN2216 Controller 4-3
Page 38
Tuning Installation and Operation Handbook
MANUAL TUNING
If for any reason automatic tuning gives unsatisfactory results, you can tune the controller
manually. There are a number of standard methods for manual tuning. The one
described here is the Ziegler-Nichols method.
With the process at its normal running temperature:
1.Set the Integral Time ‘ti’ and the Derivative Time ‘td’ to OFF.
2.Set High Cutback and Low Cutback, ‘Hcb’ and ‘Lcb’, to ‘Auto’
3.Ignore the fact that the temperature may not settle precisely at the setpoint
4.If the temperature is stable, reduce the proportional band ‘Pb’ so that the temperature
just starts to oscillate. If the temperature is already oscillating, increase the
proportional band until it just stops oscillating. Allow enough time between each
adjustment for the loop to stabilize. Make a note of the proportional band value
‘B’(engineering units) and the period of oscillation ‘T’ (seconds or minutes).
5.Set the Pb, ti, td parameter values according to the calculations given in Table 4-2.

Setting the cutback values
The above procedure sets up the parameters for optimum steady state control. If
unacceptable levels of overshoot or undershoot occur during start-up or for large step
changes in temperature, then manually set the cutback parameters Lcb and Hcb.
Proceed as follows:
1. Set the low and high cutback values to three proportional bandwidths (that is to
say, Lcb = Hcb = 3 x Pb).
2. Note the level of overshoot or undershoot that occurs for large temperature
changes (see the diagrams below).
In example (a) increase Lcb by the overshoot value. In example (b) reduce Lcb by the
undershoot value.

Where the temperature approaches setpoint from above, you can set Hcb in a similar

Tuning Installation and Operation Handbook
Integrating action and manual reset
In a full three-term controller (that is, a PID controller), the integral term ‘ti’
automatically removes steady state errors from the setpoint. If the controller is set up to
work in two-term mode (that is, PD mode), the integral term will be set to ‘OFF’. Under
these conditions the measured value may not settle precisely at setpoint. When the
integral term is set to OFF the parameter manual reset (code rES) appears in the PIDList in ‘FuLL’ Access level. This parameter represents the value of the power output
that will be delivered when the error is zero. You must set this value manually in order
to remove the steady state error.
Automatic droop compensation (Adc)
The steady state error from the setpoint, which occurs when the integral term is set to
‘OFF’, is sometimes referred to as ‘droop’. Adc automatically calculates the manual
reset value in order to remove this droop. To use this facility, you must first allow the
temperature to stabilise. Then, in the autotune parameter list, you must set Adc to
‘CALC’. The controller will then calculate a new value for manual reset, and switch
Adc to ‘mAn’.
Adc can be repeated as often as you require, but between each adjustment you must

Chapter 6 USER CALIBRATION
This chapter has five topics:
• WHAT IS THE PURPOSE OF USER CALIBRATION?
• USER CALIBRATION ENABLE
• SINGLE POINT CALIBRATION
• TWO POINT CALIBRATION
• CALIBRATION POINTS AND CALIBRATION OFFSETS
To understand how to select and change parameters in this chapter you will need to have
read Chapter 1 - Operation, Chapter 3- Access Levels and Chapter 5 - Configuration.
WHAT IS THE PURPOSE OF USER CALIBRATION?
The basic calibration of the controller is highly stable and set for life. User calibration
allows you to offset the ‘permanent’ factory calibration to either:
1.Calibrate the controller to your reference standards
2.Match the calibration of the controller to that of a particular transducer or sensor
input
3.Calibrate the controller to suit the characteristics of a particular installation.
User calibration works by introducing zero and span offsets onto the factory set
calibration. The factory set calibration can always be retrieved.

SINGLE POINT CALIBRATION
Your controller is calibrated for life against known reference sources during manufacture.
A calibration offset is often used to allow the controller to compensate for sensor and
other system errors. The normal procedure is to set up the system under test against a
known independent reference, as follows:
Set up the process to be calibrated such that the known reference displays the required
value (temperature).
Observe the reading on the controller. If it is different, proceed as follows:

TWO POINT CALIBRATION
The previous section described how to perform a single point calibration, which applies a
fixed offset over the full display range of the controller. A two-point calibration is used
to calibrate the controller at two points and apply a straight line between them. Any
readings above or below the two calibration points will be an extension of this straight
line. For this reason it is best to calibrate with the two points as far apart as possible.
Proceed as follows:
1. Decide upon the low and high points at which you wish to calibrate.
2. Perform a single point calibration at the low calibration point in the manner
described above
3. Set the process under calibration such that the known reference displays the required
higher Process Value (temperature) and allow to stabilize.

CN2216 Controller7-1
Page 60
Alarm OperationInstallation and Operation Handbook
DEFINITION OF ALARMS AND EVENTS
Alarms are used to alert an operator when a pre-set level or condition has been exceeded.
They are normally used to switch an output - usually a relay - to provide interlocking of
the machine or plant or external audio or visual indication of the condition.
Soft Alarms are indication only within the controller and are not attached to an output
(relay).
Events - can also be alarms - but are generally defined as conditions, which occur as part
of the normal operation of the plant. They do not generally require operator intervention.
An example might be to open/close a vent during a programmer cycle.
Events are referred to as Digital Output Functions in the manual. See pages 5-11 and 5-
12.
For the purposes of the operation of this instrument alarms and events can be considered
the same.
TYPES OF ALARMS
The use of alarms in your controller is extremely versatile.
Up to 4 alarms can be configured and they are found under the Alarm List in Full Access
Mode. Any combination of these 4 alarms can be attached to any one or more outputs.
NOTE: in a PID controller at least one of these outputs is used to maintain the required
temperature of the process and therefore not available for alarm assignment.
Any number of the available “soft” alarms can be combined to operate a single output
Outputs 1 and 2Are plug in modules.
Conventionally used for control outputs, e.g. Heat and
Cool, but can be used for alarms.
Output 3Is a fixed relay.
Conventionally used for alarms or events, but can be
used as a control output.

Notes:
1. PDLINK is a proprietary technique for bi-directional communication over a single
pair of wires. There are several operating modes.
In mode 1 a DC pulse output delivers a power demand signal to a SSC-TE10S solid
state (SSR) relay and the SSR responds with a single load circuit failure message.
In mode 2 a DC pulse output delivers a power demand signal to an SSC-TE10S and
the SSR responds with the ON state rms load current, and two fault messages - SSR
failure or heater circuit failure.
2. Range min and Range max: Enter a numeric value, with a decimal point if
required. Thermocouple and RTD sensor inputs will always display over the full
operating range shown in the sensor input table. The values entered here will act as
low and high setpoint limits. For linear inputs, the values entered are used to scale
the input signal.

GENERAL
The information contained in this manual is subject to change without notice. While
every effort has been made to ensure the accuracy of the information, Omega shall not be
held liable for errors contained herein.
Unpacking and storage
The packaging should contain an instrument mounted in its sleeve, two mounting
brackets for panel installation and this operating book. Certain ranges are supplied with
an input adapter.
If on receipt, the packaging or the instrument is damaged, do not install the product but
contact Omega.
If the instrument is to be stored before use, protect from humidity and dust in an ambient
temperature range of -30oC to +75oC.
SERVICE AND REPAIR
This controller has no user serviceable parts. Contact Omega for repair.
Caution: Charged capacitors
Before removing an instrument from its sleeve, disconnect the supply and wait at least
two minutes to allow capacitors to discharge. It may be convenient to partially withdraw
the instrument from the sleeve, then pause before completing the removal. In any case,
avoid touching the exposed electronics of an instrument when withdrawing it from the
sleeve. Failure to observe these precautions may cause damage to components of the
instrument or some discomfort to the user.
CN2216 ControllerB-1
Page 70
Safety InformationInstallation and Operation Handbook
Electrostatic discharge precautions
When the controller is removed from its sleeve, some of the exposed electronic
components are vulnerable to damage by electrostatic discharge from someone handling
the controller. To avoid this, before handling the unplugged controller discharge yourself
to ground.
Cleaning
Do not use water or water based products to clean labels or they will become illegible.
Isopropyl alcohol may be used to clean labels. A mild soap solution may be used to
clean other exterior surfaces of the product.
INSTALLATION SAFETY REQUIREMENTS
Safety Symbols
Various symbols are used on the instrument; they have the following meaning:
Caution, (refer to the
!
accompanying documents)
The functional earth connection is not required for safety purposes but to ground RFI filters.
Personnel
Installation must only be carried out by qualified personnel.
Enclosure of live parts
To prevent hands or metal tools touching parts that may be electrically live; the controller
must be installed in an enclosure.
Caution: Live sensors
The dc pulse and PDLINK outputs are electrically connected to the main PV input,
(thermocouple etc.). If the temperature sensor is connected directly to an electrical heating
element then these non-isolated inputs and outputs will also be live. The controller is
designed to operate under these conditions. However you must ensure that this will not
damage other equipment connected to these inputs and outputs and that service personnel do
not touch connections to these i/o while they are live. With a live sensor, all cables
connectors and switches for connecting the sensor and non-isolated inputs and outputs must
be mains rated. The dc output has a 42V functional insulation to PV.
Wiring
It is important to connect the controller in accordance with the wiring data given in this
handbook. Take particular care not to connect AC supplies to the low voltage sensor
input or other low level inputs and outputs. Only use copper conductors for connections,
(except thermocouple). Ensure that the wiring of installations comply with all local
wiring regulations. In the USA use NEC Class 1 wiring methods.
Functional earth
(ground) terminal
B-2CN2216 Controller
Page 71
Installation and Operation HandbookSafety Information
Power Isolation
The installation must include a power isolating switch or circuit breaker that disconnects
all current carrying conductors. The device should be mounted in close proximity to the
controller, within easy reach of the operator and marked as the disconnecting device for
the instrument.
Earth leakage current
Due to RFI Filtering there is an earth leakage current of less than 0.5mA. This may affect
the design of an installation of multiple controllers protected by Residual Current Device,
(RCD) or Ground Fault Detector, (GFD) type circuit breakers.
Overcurrent protection
To protect the internal PCB tracking within the controller against excess currents, the AC
power supply to the controller and power outputs must be wired through the fuse or
circuit breaker specified in the technical specification.
Voltage rating
The maximum continuous voltage applied between any connection to ground must not
exceed 264Vac.
The controller should not be wired to a three-phase supply with an unearthed star
connection. Under fault conditions such a supply could rise above 264Vac with respect
to ground and the product would not be safe.
Voltage transients across the power supply connections, and between the power supply
and ground, must not exceed 2.5kV. Where occasional voltage transients over 2.5kV are
expected or measured, the power installation to both the instrument supply and load
circuits should include a transient limiting device.
These units will typically include gas discharge tubes and metal oxide varistors that limit
and control voltage transients on the supply line due to lightning strikes or inductive load
switching. Devices are available in a range of energy ratings and should be selected to
suit conditions at the installation.
Conductive pollution
Electrically conductive pollution must be excluded from the cabinet in which the
controller is mounted. For example, carbon dust is a form of electrically conductive
pollution. To secure a suitable atmosphere, install an air filter to the air intake of the
cabinet. Where condensation is likely, for example at low temperatures, include a
thermostatically controlled heater in the cabinet.
Grounding of the temperature sensor shield
In some installations it is common practice to replace the temperature sensor while the
controller is still powered up. Under these conditions, as additional protection against
electric shock, we recommend that the shield of the temperature sensor be grounded. Do
not rely on grounding through the framework of the machine.
CN2216 ControllerB-3
Page 72
Safety InformationInstallation and Operation Handbook
Over-temperature protection
When designing any control system it is essential to consider what will happen if any part
of the system should fail. In temperature control applications the primary danger is that
the heating will remain constantly on. Apart from spoiling the product, this could
damage any process machinery being controlled or even cause a fire.
Reasons why the heating might remain constantly on include:
• the temperature sensor becoming detached from the process
• thermocouple wiring becoming short circuit;
• the controller failing with its heating output constantly on
• an external valve or contactor sticking in the heating condition
• the controller setpoint set too high.
Where damage or injury is possible, we recommend fitting a separate over-temperature
protection unit, with an independent temperature sensor, which will isolate the heating
circuit.
Please note that the alarm relays within the controller will not give protection under all
failure conditions.
INSTALLATION REQUIREMENTS FOR EMC
To ensure compliance with the European EMC directive certain installation precautions
are necessary as follows:
• When using relay or AC SSR outputs it may be necessary to fit a filter suitable for
suppressing the conducted emissions. The filter requirements will depend on the type
of load.
• If the unit is used in tabletop equipment, which is plugged into a standard power
socket, then it is likely that compliance to the commercial and light industrial
emissions standard is required. In this case to meet the conducted emissions
requirement, a suitable mains filter should be installed.
• Routing of wires
To minimise the pick-up of electrical noise, the low voltage DC connections and the
sensor input wiring should be routed away from high-current power cables. Where it is
impractical to do this, use shielded cables with the shield grounded at both ends. In
general keep cable lengths to a minimum.
