Current Transformer
The current transformer input is an optional input in all
3200 series controllers.
It can be connected to monitor the rms current in an
electrical load and to provide load diagnostics. The
following fault conditions can be detected: SSR (solid
state relay) short circuit, heater open circuit and partial
load failure. These faults are displayed as alarm
messages on the controller front panel.
CT Input
2.12
General Note About Relays and
Inductive Loads
High voltage transients may occur when switching
inductive loads such as some contactors or solenoid
valves. Through the internal contacts, these transients
may introduce disturbances which could affect the
performance of the instrument.
For this type of load it is recommended that a ‘snubber’
is connected across the normally open contact of the
relay switching the load. The snubber recommended
consists of a series connected resistor/capacitor (typically
15nF/100Ω). A snubber will also prolong the life of the
relay contacts.
CT
C
Note: C terminal is common to both the CT input and
Digital input A. They are, therefore, not isolated from
each other or the PV input.
•
CT input current: 0-50mA rms (sine wave, calibrated)
50/60Hz
•
A burden resistor, value 10Ω, is fitted inside the
controller.
•
It is recommended that the current
transformer is fitted with a voltage
limiting device to prevent high voltage
transients if the controller is unplugged.
For example, two back to back zener diodes. The
zener voltage should be between 3 and 10V, rated
at 50mA.
•
CT input resolution: 0.1A for scale up to 10A, 1A for
scale 11 to 100A
•
CT input accuracy: +4% of reading.
A snubber should also be connected across the output
terminal of a triac output to prevent false triggering
under line transient conditions.
WARNING
When the relay contact is open or it is connected to
a high impedance load, the snubber passes a current
(typically 0.6mA at 110Vac and 1.2mA at 240Vac).
You must ensure that this current will not hold on
low power electrical loads. If the load is of this type
the snubber should not be connected.

Digital Inputs A & B
Digital input A is an optional input in all 3200 series

standard EN 61010.
Electromagnetic compatibility
This controller conforms with the essential protection
requirements of the EMC Directive 2004/108/EC, by the
application of a Technical Construction File. This
instrument satisfies the general requirements of the
industrial environment defined in EN 61326. For more
information on product compliance refer to the
Technical Construction File.
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, your
supplier 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 an Installation & Operating guide. Certain ranges are
supplied with an input adapter.
If on receipt, the packaging or the instrument are
damaged, do not install the product but contact your
supplier. If the instrument is to be stored before use,
protect from humidity and dust in an ambient
temperature range of -30oC to +75oC.
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.

 Helpful hints in this manual
Personnel
Installation must only be carried out by suitably qualified
personnel in accordance with the instructions in this
handbook.
Enclosure of Live Parts
To prevent hands or metal tools touching parts that may
be electrically live, the controller must be enclosed in an
enclosure.
SERVICE AND REPAIR
Caution: Live sensors
This controller has no user serviceable parts. Contact
your supplier for repair.
The controller is designed to operate if the temperature
sensor is connected directly to an electrical heating
element. However you must ensure that service
personnel do not touch connections to these inputs
while they are live. With a live sensor, all cables,
connectors and switches for connecting the sensor must
be mains rated.
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.

Wiring
It is important to connect the controller in accordance
with the wiring data given in this guide. 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 inputs) and ensure that the wiring of
installations comply with all local wiring regulations. For
example in the UK use the latest version of the IEE wiring
regulations, (BS7671). In the USA use NEC Class 1 wiring
methods.

User Manual
Power Isolation
The installation must include a power isolating switch or
circuit breaker. This device should be in close proximity to
the controller, within easy reach of the operator and marked
as the disconnecting device for the instrument.
Overcurrent protection
The power supply to the system should be fused
appropriately to protect the cabling to the units.
Voltage rating
The maximum continuous voltage applied between any
of the following terminals must not exceed 240Vac:
•
relay output to logic, dc or sensor connections;
•
any connection to ground.
The controller must not be wired to a three phase supply
with an unearthed star connection. Under fault
conditions such a supply could rise above 240Vac with
respect to ground and the product would not be safe.
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 in conditions
of conductive pollution, fit 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.
This product has been designed to conform to BSEN61010
installation category II, pollution degree 2. These are
defined as follows:Installation Category II (CAT II)
The rated impulse voltage for equipment on nominal 230V
supply is 2500V.
Pollution Degree 2
Normally only non conductive pollution occurs.
Occasionally, however, a temporary conductivity caused by
condensation shall be expected.
3200 Series
•
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:
•
For general guidance refer to Eurotherm Controls
EMC Installation Guide, HA025464.
•
When using relay outputs it may be necessary to fit a
filter suitable for suppressing the emissions. The
filter requirements will depend on the type of load.
•
If the unit is used in table top 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.
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 is grounded. Do not rely on
grounding through the framework of the machine.
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:
•
18
the temperature sensor becoming detached from the
process

Additional alarm messages may be shown such as
CONTROL LOOP BROKEN. This occurs if the controller
does not detect a change in process value following a
change in output demand after a suitable delay time.
Another alarm message may be INPUT SENSOR BROKEN
(SBr). This occurs if the sensor becomes open circuit;
the output level will adopt a ‘SAFE’ value which can be
set up in Operator Level 3, see section 11.2.

The action which takes place depends on the type of
alarm configured:Non
latching
A non latching alarm will reset itself when the
alarm condition is removed. By default alarms
are configured as non-latching, de-energised in
alarm.
Auto
Latching
An auto latching alarm requires
acknowledgement before it is reset. The
acknowledgement can occur BEFORE the
condition causing the alarm is removed.
Manual
Latching
The alarm continues to be active until both the
alarm condition is removed AND the alarm is
acknowledged. The acknowledgement can only
occur AFTER the condition causing the alarm is
removed.
By default alarms are configured as non-latching, deenergised in alarm. To configure latched alarms, refer to
section 12.3.1.
Note: If remote setpoint is configured ensure that the
remote input is connected or the relevant rear terminals
are linked. If the remote setpoint input is left open
circuit the alarm beacon will light.

Timer Operation
An internal timer can be set to operate in one of four different modes. The mode is set in Level 2 by the ‘TM.CFG’
(timer configuration) parameter. Each Timing Mode is described in the pages that follow.
5.5
Dwell Timer
A dwell timer (‘TM.CFG’ = ‘DwEl’) is used to control a process at a fixed temperature for a defined period.
In reset the controller behaviour depends on the configuration of the END state parameter. See opposite.
In run the heating or cooling will come on. Timing starts when the temperature is within the threshold ‘THRES’ of the
setpoint. If the threshold is set to OFF the timing starts immediately.
If setpoint ramping is enabled, then the ramp completes before the timer starts.
In the END state the behaviour is determined by the parameter ‘END.T’ (End type):
OFF The heating and cooling is turned OFF (resets to Off)
Dwel Controls at setpoint1 (resets to Setpoint 1)
SP2 Controls at setpoint 2 (resets to Setpoint 1)
rES Reset reverts to SP1.– (added from version V2.13)

Programmer
‘TM.CFG’ = ‘ProG’.
A programmer is generally used to control the rate of change of the process variable (PV) over several segments. The PV
is generally temperature and this will be referred to in the following examples.
Function code CP is an eight segment programmer consisting of four ramp/dwell pairs. Each ramp consists of a
controlled rate of change of setpoint to a target level. Each ramp is followed by a dwell at that level. The ramp rate,
target level and dwell time are set by the user. An example of a program profile is shown in the diagram below.

Programmer Servo Mode and Power Cycling
The way in which the program starts when ‘Run’ is selected or after the power is turned off and on again, is determined
by the SERVO MODE parameter, as follows:SERVO MODE
SP
The program will start from the current setpoint value.
On recovery from power failure, the program will reset. It will require to be run again manually.
The working setpoint will revert to SP1 or SP2 (depending on which was selected) and the whole
program is repeated.
PV
The program will start from the measured temperature.
On recovery from power failure, the program will reset. It will require to be run again manually,
but it will start at the value of the PV at the point when the programmer is run again.
SP.rb
On recovery from power failure, the program will automatically run at the last ramp rate from the
current setpoint value, see the sketches below.
PV.rb
The program will start from the measured temperature.
On recovery from power failure, the program will automatically run at the last ramp rate from the

6. Access to Further Parameters
6.1.2
6.1
This level makes available all parameters including the
operation parameters so that there is no need to switch
between configuration and operation levels during
commissioning. It is designed for those who may wish
to change the fundamental characteristics of the
instrument to match the process.
Parameter Levels
Parameters are available under different levels of
security and are defined as Level 1 (Lev1), Level 2
(Lev2), Level 3 (Lev 3) and Configuration (C on f).
Level 1 has no passcode since it contains a minimal set
of parameters generally sufficient to run the process on
a daily basis.
Level 2 allows access to parameters which may used in
commissioning a controller or settings between
different products or batches.
Level 1 and Level 2 operation has been described in the
previous sections.
Level 3 and Configuration level parameters are also
available as follows:-
6.1.1
Level 3
Level 3 makes all operating parameters available and
alterable (if not read only). It is typically used when
commissioning a controller.
Examples of parameters available in Level 3 are:Range limits, setting alarm levels, communications
address.
The instrument will continue to control when in Levels
1, 2 or 3.

WARNING
Configuration level gives access to a wide range of
parameters which match the controller to the
process. Incorrect configuration could result in
damage to the process being controlled and/or
personal injury. It is the responsibility of the
person commissioning the process to ensure that
the configuration is correct.
In configuration level the controller is not

PV The meter displays the current Process Variable
scaled between the range high and low values. Provides
an indication of the current temperature relative to the
range of a process.
Err The meter displays the process error (i.e. the
difference between the current temperature and the
setpoint), scaled between +10 degrees and -10 degrees.
This provides a visual indication of whether the process
is close to setpoint.
Amps The meter shows a representation of the
instantaneous current through a load monitored using a
current transformer, scaled between 0 Amps and the
configured range of the Current Transformer. It may be
used to visually indicate the health of the heating
elements, since in normal use it will tend to flick from a
low reading when the heating is off, to a higher reading
when the heating is on. If the needle does not return to
a low value, the SSR may be conducting regardless of
the logic signal driving it. If the needle does not reach
the expected level it is likely that one or more of the
heater elements has burned out.
Edit keys locked. Parameters cannot be changed but
viewed only. However, it is possible to run, hold and
reset timer and acknowledge alarms.
Lcur The meter displays a representation of the On
State Current in a load monitored by the current
transformer option. In normal operation it will tend to
remain static and provides an alternative means of
monitoring the health of a heating element to the
'Amps' option.

Feature Passcodes These parameters were added in

controller to be field upgraded with additional
chargeable features. To upgrade, contact Eurotherm
and provide the existing number codes. ‘Pass2’ is read
only and is required to provide Eurotherm with the
current instrument features. You will be given a
numeric code to enter as the new ‘PassC’ parameter.

HEAT The meter shows a representation of the heat
output being applied by the control loop to the load. It
is scaled between 0 and 100% full scale deflection.
Op The meter displays the current Control Output
setting scaled between the low and high output power
limits. In a motorised valve controller (option VC or VP)
this is the ‘inferred’ position of the valve
COOL The meter shows a representation of the cool
output being applied by the control loop to the load. It
is scaled between 0 and 100% full scale deflection.
C.OP The meter displays the current output power
setting scaled between -100 and 100%, so that a value of
zero is centred in the display. This indicates whether
the controller is currently applying heating or cooling.
w.sp The meter shows a representation of the current
working setpoint, scaled between the setpoint high and

Or
The Temperature (or Process Value, PV) is measured by
the sensor and compared with a Setpoint (SP) set by the
user.
These parameters are found in lists and the name of
each list corresponds with the name of the function
block shown in the above diagram.
The purpose of the control block is to reduce the
difference between SP and PV (the error signal) to zero
by providing a compensating output to the plant via the
output driver blocks.
The above block diagram applies to 3208, 32h8 and
3204 controllers.
For 3216 Output 3 and Logic Input B are not present.
The timer and alarms blocks may be made to operate
on a number of parameters within the controller, and
digital communications provides an interface to data
collection and control.
The way in which each block performs is defined by its
internal parameters. Some of these parameters are
available to the user so that they can be adjusted to suit
the characteristics of the process which is to be
controlled.

Parameters in the input list configure the input to match your sensor. These parameters provide the following features:Input Type and
linearisation
Thermocouple (TC) and 3-wire resistance thermometer (RTD) temperature detectors
Linear input (-10 to +80mV). 0-10V using external voltage divider. mA assumes a 2.49Ω
external shunt.
See the table in section 0. for the list of input types available
Display units and
resolution
The change of display units and resolution will all the parameters related to the process
variable
Input filter
First order filter to provide damping of the input signal. This may be necessary to prevent
the effects of excessive process noise on the PV input from causing poor control and
indication. More typically used with linear process inputs.
Fault detection
Sensor break is indicated by an alarm message ‘Sbr’. For thermocouple it detects when
the impedance is greater than pre-defined levels; for RTD when the resistance is less than
12Ω.
User calibration
Either by simple offset or by slope and gain. See section 8.2. for further details.
Over/Under range
When the input signal exceeds the input span by more than 5% the PV will flash indicating
under or over range. If the value is too high to fit the number of characters on the display
‘HHHH’ or ‘LLLL’ will flash. The same indications apply when the display is not able to show
the PV, for example, when the input is greater than 999.9oC with one decimal point.

Alarm State
ALM beacon flashes when an alarm occurs.
Output alarm relay activates. ACK has no

When the sensor break condition is no longer
applicable it is necessary to press ACK to cancel
the alarm.
Note:- When the SAFE output value is outside the OP.LO and OP.HI limits it will be clipped into range and the controller
will use the value (i.e. adjusting OP.LO or OP.HI changes the SAFE value so that it is in range).
It could take either the lower or higher OP limit depending on its value and which limit has changed. Therefore, if SAFE =
0 and OP.LO is changed to 10, SAFE will also be set to 10. If SAFE = 50 and OP.HI is changed to 40, SAFE will change to
40.

PV Offset
8.3
All ranges of the controller have been calibrated against
traceable reference standards. This means that if the
input type is changed it is not necessary to calibrate the
controller. There may be occasions, however, when you
wish to apply an offset to the standard calibration to
take account of known errors within the process, for
example, a known sensor error or a known error due to
the positioning of the sensor. In these instances it is not
advisable to change the reference (factory) calibration,
but to apply a user defined offset.
PV Offset applies a single offset to the temperature or
process value over the full display range of the controller
and can be adjusted in Level 3. It has the effect of
moving the curve up a down about a central point as
shown in the example below:Display
Reading
PV Input Scaling
Input scaling applies to the linear mV input range only.
This is set by configuring the INPUT TYPE parameter to
mV and has an input range of –10 to 80mV. Using an
external burden resistor of 2.49Ω, the controller can be
made to accept 4-20mA from a current source. Scaling
of the input will match the displayed reading to the
electrical input levels from the transducer. PV input
scaling can only be adjusted in Configuration level and is
not provided for direct thermocouple or RTD inputs.
The graph below shows an example of input scaling,
where it is required to display 2.0 when the input is 4mV
and 500.0 when the input is 20mV .
If the input exceeds +5% of the mV.Lo or mV.Hi settings,
sensor break will be displayed.
Display
Reading
For mA inputs
4-20mA = 9.96-49.8mV with
2.49Ω load resistor
0-20mA = 0-49.8mV with
2.49Ω load resistor
mA input will detect sensor
break if mA < 3mA

Remote Digital Setpoint Select and
Remote Fail
These parameters were added in software version 1.11,
and subsequent versions, and are associated with the
retransmission of remote setpoint through master
comms (see section 15.2.1). ‘rmt’ allows the remote
setpoint to be selected via a digital input and ‘rmt.F’ is a
flag which is set if no comms activity is detected for 5
seconds or more when writing to the remote setpoint.
The flag is reset when writing to the remote setpoint
resumes.
9.1.3
‘Inverted’ means a relay output is energised for 0% PID
demand
For an alarm output set this parameter to ‘Inv’ so that
it de-energises to the alarm state.
If the module is an input, ‘normal’ means the function is
activated when the input contact is closed, and ‘inverted’
means the function is activated when the input contact is
open.
Source
The four parameters SOURCE A, SOURCE B, SOURCE C,
and SOURCE D appear when the output is configured as
a digital output i.e. ‘-.FUNC ’ = ‘d.Out’ and provide the
facility to connect up to four alarms or events to operate
a single output (normally configured as a relay). If any
one of the events becomes true then the output relay
will operate.

Digital Input A. This is an optional input wired to terminals C and LA. The input is typically from a voltage free contact,
which can be configured to operate a number of functions as determined by parameters in the LA List.
☺ 3216 controllers can be fitted with optional EIA232 digital communications. In this case the digital input is not
available.
Note: Terminal C is common to the CT input and is, therefore, not isolated from the CT.

Current Transformer Input Parameters
This is optional on 3200 controllers and can measure, via an external current transformer, the current flowing through the
electrical load when the heat output is ‘on’ (load current) and also when it is ‘off’ (leakage current).
☺
3216 controllers can be fitted with optional EIA232 digital communications. In this case the current transformer
input is not available.
Alarm
If the load current is lower than a threshold limit or the leakage current is higher than a
threshold limit, then an alarm triggers. The hysteresis to exit from either of these alarm
conditions is fixed at 2% of the current transformer span.

An application example might be to use
SP1 for normal operation and SP2 to
maintain a low overnight temperature.
Setpoint

temperature control loop is shown below:Control Output

11.1
Heater
The actual temperature measured at the process (PV) is connected
to the input of the controller. This is compared with a setpoint (or
required) temperature (SP). If there is an error between the set
and measured temperature the controller calculates an output
value to call for heating or cooling. The calculation depends on
the process being controlled but normally uses a PID algorithm.
The output(s) from the controller are connected to devices on the
plant which cause the heating (or cooling) demand to be adjusted
which in turn is detected by the temperature sensor. This is
referred to as the control loop or closed loop control.
Types of Control
Three types of control loop may be configured. These are On/Off control, PID control or control of motorised valves
11.1.1
On/Off Control
On/Off control is the simplest means of control and simply turns heating power on when the PV is below setpoint and off
when it is above setpoint. As a consequence, On/Off control leads to oscillation of the process variable. This oscillation
can affect the quality of the final product and may be used on non-critical processes. A degree of hysteresis must be set
in On/Off control if the operation of the switching device is to be reduced and relay chatter is to be avoided.
If cooling is used, cooling power is turned on when the PV is above setpoint and off when it is below.
It is suitable for controlling switching devices such as relays, contactors, triacs or digital (logic) devices.
11.1.2
PID Control
PID, also referred to as ‘Three Term Control’, is an algorithm which continuously adjusts the output, according to a set of
rules, to compensate for changes in the process variable. It provides more stable control but the parameters need to be
set up to match the characteristics of the process under control.
The three terms are:
Proportional band PB
Integral time TI
Derivative time TD
The output from the controller is the sum of the contributions from these three terms. The combined output is a
function of the magnitude and duration of the error signal, and the rate of change of the process value.
It is possible to turn off integral and derivative terms and control on proportional only (P), proportional plus integral (PI)
or proportional plus derivative (PD).
PI control might be used, for example, when the sensor measuring an oven temperature is susceptible to noise or other
electrical interference where derivative action could cause the heater power to fluctuate wildly.
PD control may be used, for example, on servo mechanisms.
In addition to the three terms described above, there are other parameters which determine how well the control loop
performs. These include Cutback terms, Relative Cool Gain, Manual Reset and are described in detail in subsequent
sections.

Motorised Valve Control
This algorithm is designed specifically for positioning motorised valves. It operates in boundless mode (sometimes called
unbounded) which does not require a position feedback potentiometer to operate. It is a velocity mode algorithm which
directly controls the direction and velocity of the movement of the valve in order to minimise the error between the
setpoint and the PV. It uses triac or relay outputs to drive the valve motor.
11.1.3.1 Motorised Valve Control in Manual mode
When manual is selected the algorithm predicts where the valve will move to based on the edit of the manual power.
Effectively, when the raise or lower key is pressed, +100% or –100% velocity is used for the duration of the key press and
the raise or lower output is turned on. In boundless mode it is essential that the Motor Travel Time, ‘MTR.T’ is set
correctly in order for the integral time to calculate correctly. Motor travel time is defined as valve fully open – valve
fully closed - it is not necessarily the time printed on the motor since, if mechanical stops have been set on the motor,
the travel time of the actual valve may be different. Also, if the travel time for the valve is set correctly, the position
indicated on the controller will fairly accurately match the actual valve position.
Every time the valve is driven to its end stops the algorithm is reset to 0% or 100% to compensate for any changes which
may occur due to wear in linkages or other mechanical parts.

Proportional Band ‘PB’
The proportional band, or gain, delivers an output which is proportional to the size of the error signal. It is the range
over which the output power is continuously adjustable in a linear fashion from 0% to 100% (for a heat only controller).
Below the proportional band the output is full on (100%), above the proportional band the output is full off (0%) as
shown in the diagram below.
The width of the proportional band determines the magnitude of the response to the error. If it too narrow (high gain)
the system oscillates by being over responsive. If it is too wide (low gain) the control is sluggish. The ideal situation is
when the proportional band is as narrow as possible without causing oscillation.

The diagram also shows the effect of narrowing proportional band to the point of oscillation. A wide proportional band
results in straight line control but with an appreciable initial error between setpoint and actual temperature. As the band
is narrowed the temperature gets closer to setpoint until finally becoming unstable.
The proportional band may be set in engineering units or as a percentage of the controller range.
11.2.2
Integral Term ‘TI’
In a proportional only controller, an error between setpoint and PV must exist for the controller to deliver power.
Integral is used to achieve zero steady state control error.
The integral term slowly shifts the output level as a result of an error between setpoint and measured value. If the
measured value is below setpoint the integral action gradually increases the output in an attempt to correct the error. If
it is above setpoint integral action gradually decreases the output or increases the cooling power to correct the error.
The diagram below shows the result of introducing integral action.

Time
The units for the integral term are measured in time (1 to 9999 seconds in 3200 controllers). The longer the integral time
constant, the more slowly the output is shifted and results in a sluggish response. Too small an integral time will cause
the process to overshoot and even oscillate. The integral action may be disabled by setting its value to Off.

Derivative Term ‘TD’
Derivative action, or rate, provides a sudden shift in output as a result of a rapid change in error. If the measured value
falls quickly derivative provides a large change in output in an attempt to correct the perturbation before it goes too far.
It is most beneficial in recovering from small perturbations.

Time
The derivative modifies the output to reduce the rate of change of error. It reacts to changes in the PV by changing the
output to remove the transient. Increasing the derivative time will reduce the settling time of the loop after a transient
change.
Derivative is often mistakenly associated with overshoot inhibition rather than transient response. In fact, derivative
should not be used to curb overshoot on start up since this will inevitably degrade the steady state performance of the
system. Overshoot inhibition is best left to the approach control parameters, High and Low Cutback, section 11.2.5.
Derivative is generally used to increase the stability of the loop, however, there are situations where derivative may be the
cause of instability. For example, if the PV is noisy, then derivative can amplify that noise and cause excessive output
changes, in these situations it is often better to disable the derivative and re-tune the loop.
If set to Off(0), no derivative action will be applied.
In 3200 controllers derivative is calculated on change of PV. For applications such as furnace temperature control, it is
common practice to use Derivative on PV to prevent thermal shock caused by a sudden change of output as a result of a
change in setpoint.
11.2.4
Relative Cool Gain ‘R2G’
The proportional band parameter ‘PB’ adjusts the proportional band for the heating output. Relative cool gain adjusts the
cooling proportional band relative to the heating proportional band. If the rate of heating and rate of cooling are widely
different it may be necessary to manually adjust Relative Cool Gain to achieve the optimum settings for the cooling
proportional band. A nominal setting of around 4 is often used.
Note, This parameter is set automatically when Auto-tune is used unless the parameter ‘AT.R2G’ is set to ‘No’ - see
section 11.4.

High and Low Cutback
Cutback high ‘CBHI’ and Cutback low ‘CBLO’ are values that modify the amount of overshoot, or undershoot, that occurs
during large step changes in PV (for example, under start-up conditions). They are independent of the PID terms which
means that the PID terms can be set for optimal steady state response and the cutback parameters used to modify any
overshoot which may be present.
Cutback involves moving the proportional band towards the cutback point nearest the measured value whenever the
latter is outside the proportional band and the power is saturated (at 0 or 100% for a heat only controller). The
proportional band moves downscale to the lower cutback point and waits for the measured value to enter it. It then
escorts the measured value with full PID control to the setpoint. In some cases it can cause a ‘dip’ in the measured value
as it approaches setpoint, as shown in the diagram below, but generally decreases the time needed to bring the process
into operation.
The action described above is reversed for falling temperature.
If cutback is set to Auto the cutback values are automatically configured to 3*PB.

Manual Reset
In a full three-term controller (that is, a PID controller), the integral term automatically removes the steady state error
from the setpoint. If the controller is set as a PD controller, the integral term will be set to ‘OFF’. Under these conditions
the measured value may not settle precisely at setpoint. The Manual Reset parameter (M R ) 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.
11.2.7
Control Action
When set to reverse (R E V ) the output increases when the PV is below setpoint. This is the best setting for heating
control.
For cooling control only set Control Action to direct (D IR ).
11.2.8
Loop Break
The loop is considered to be broken if the PV does not respond to a change in the output. Since the time of response
will vary from process to process the Loop Break Time parameter allows a time to be set before a Loop Break Alarm is
initiated. In these circumstances the output power will drive to high or low limit. For a PID controller, if the PV has not
moved by 0.5 x Pb in the loop break time the loop is considered to be in break. The loop break time is set by the Autotune, a typical value is 12 x Td. For an On/Off controller Loop Break Time is not shown and loop break alarm is inhibited.
11.2.9
Cooling Algorithm
The method of cooling may vary from application to application.
For example, an extruder barrel may be cooled by forced air (from a fan), or by circulating water or oil around a jacket.
The cooling effect will be different depending on the method. The cooling algorithm may be set to linear where the
controller output changes linearly with the PID demand signal, or it may be set to water, oil or fan where the output
changes non-linearly against the PID demand. The algorithm provides optimum performance for these methods of
cooling.

Tuning
In tuning, you match the characteristics (PID parameters) of the controller to those of the process being controlled in
order to obtain good control. Good control means:
•
Stable, ‘straight-line’ control of the PV at setpoint without fluctuation
•
No overshoot, or undershoot, of the PV setpoint
•
Quick response to deviations from the setpoint caused by external disturbances, thereby rapidly restoring the PV to
the setpoint value.
Tuning involves setting the following parameters:Proportional Band ‘PB’, Integral Time ‘TI’, Derivative Time ‘TD’, Cutback High ‘CBHI’, Cutback Low ‘CBLO’, and Relative
Cool Gain ‘R2G’ (applicable to heat/cool systems only).
The controller is shipped with these parameters set to default values. In many cases the default values will give adequate
stable straight line control, however, the response of the loop may not be ideal. Because the process characteristics are
fixed by the design of the process it is necessary to adjust the control parameters in the controller to achieve best
control. To determine the optimum values for any particular loop or process it is necessary to carry out a procedure
called loop tuning. If significant changes are later made to the process which affect the way in which it responds it may
be necessary to retune the loop.
Users have the choice of tuning the loop automatically or manually. Both procedures require the loop to oscillate and
both are described in the following sections.
11.3.1
Loop Response
If we ignore the situation of loop oscillation, there are three categories of loop performance:
Under Damped - In this situation the terms are set to prevent oscillation but do lead to an overshoot of the Process
Value followed by decaying oscillation to finally settle at the Setpoint. This type of response can give a minimum time to
Setpoint but overshoot may cause problems in certain situations and the loop may be sensitive to sudden changes in
Process Value. This will result in further decaying oscillations before settling once again.
Critically Damped - This represents an ideal situation where overshoot to small step changes does not occur and the
process responds to changes in a controlled, non oscillatory manner.
Over Damped - In this situation the loop responds in a controlled but sluggish manner which will result in a loop
performance which is non ideal and unnecessarily slow.
The balancing of the P, I and D terms depends totally upon the nature of the process to be controlled.
In a plastics extruder, for example, a barrel zone will have a different response to a die, casting roll, drive loop, thickness
control loop or pressure loop. In order to achieve the best performance from an extrusion line all loop tuning
parameters must be set to their optimum values.
11.3.2
Initial Settings
In addition to the tuning parameters listed in section 11.3 above, there are a number of other parameters which can have
an effect on the way in which the loop responds. Ensure that these are set before either manual or automatic tuning is
initiated. Parameters include, but are not limited to:Setpoint. Set this as closely as practicable to the actual setpoint in normal operation.
Load Conditions. Set the load conditions as closely as possible to those which will be met in practice. For example, in a
furnace or oven application a representative load should be included, an extruder should be running, etc.
Heat/Cool Limits. The minimum and maximum power delivered to the process may be limited by the parameters
‘OUTPUT LOW’ and ‘OUTPUT HIGH’ both of which are found in the Control list. For a heat only controller the default
values are 0 and 100%. For a heat/cool controller the defaults are -100 and 100%. Although it is expected that most
processes will be designed to work between these limits there may be instances where it is desirable to limit the power
delivered to the process. For example, if driving a 220V heater from a 240V source the heat limit may be set 80% to
ensure that the heater does not dissipate more than its maximum power.
 The measured value must oscillate to some degree for the tuner to be able to calculate values. The limits must be
set to allow oscillation about the setpoint.

Channel 2 Deadband. In controllers fitted with a second (cool) channel a parameter ‘D.BAND’ is also available in the
Control list, which sets the distance between the heat and cool proportional bands. The default value is 0% which means
that heating will turn off at the same time as cooling turns on. The deadband may be set to ensure that there is no
possibility of the heat and cool channels being on together, particularly when cycling output stages are installed.
Minimum Pulse Time. If either or both of the output channels is fitted with a relay, triac or logic output, the parameter
‘-.PLS’ will appear in the relevant output list (IO-1 list, OP-2 list, OP-3 list or AA Relay Output list). This is the cycling time
for a time proportioning output and should be set correctly before tuning is started.
Input Filter Time Constant. The parameter ‘FILTER TIME’ should be set before tuning the loop. It is found in the INPUT
List.
Valve Travel Time. If the output is a motor valve positioner the parameter ‘MTR.T’ (Control List) should be set to the
time that it takes for the motor to travel from its fully closed to its fully open position.
Other Considerations
•
If a process includes adjacent interactive zones, each zone should be tuned independently.
•
It is always better to start a tune when the PV and setpoint are far apart. This allows start up conditions
to be measured and cutback values to be calculated more accurately.
•
In a programmer/controller tuning should only be attempted during dwell periods and not during ramp
stages. If a programmer/controller is tuned automatically put the controller into Hold during each dwell
period whilst autotune is active. It may be worth noting that tuning, carried out in dwell periods which
are at different extremes of temperature may give different results owing to non linearity of heating (or
cooling).

Automatic Tuning
Auto Tune automatically sets the following parameters:Proportional Band ‘PB’
Integral Time ‘Ti’
Derivative Time ‘Td’
Cutback High ‘CBHI’
Cutback Low ‘CBLO’
If ‘Ti’ and/or ‘Td’ is set to OFF, because you wish to use PI, PD or P only control, these

If CBH and/or CBL is set to ‘Auto’ these terms will remain at Auto after an autotune, i.e.

For autotune to set the cutback values, CBHI and CBLO must be set to a value (other than
Auto) before autotune is started.
Autotune will never return cutback values which are less than 1.6*PB.
Relative Cool Gain ‘R2G’
R2G is only calculated if the controller is configured as heat/cool.
Following an autotune, ‘R2G’ is always limited to between 0.1 and 10. If the calculated

Loop Break Time ‘LBT’
Following an autotune, ‘LBT’ is set to 2*Ti (assuming the integral time is not set to OFF).
If ‘Ti’ is set to OFF then ‘LBT’ is set to 12*Td.
Auto tune uses the ‘one-shot’ tuner which works by switching the output on and off to induce an oscillation in the
process value. From the amplitude and period of the oscillation, it calculates the tuning parameter values. The autotune
sequence for different conditions is described in sections 11.3.5 to 0.
11.3.4
To Start Autotune
In operator levels 2 or 3, set the ‘AUTO-TUNE ENABLE’ parameter to ‘On’.
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.
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), it may be necessary to tune again for the new conditions.
The auto tune algorithm reacts in different ways depending on the initial conditions of the plant. The explanations given
in this section are for the following conditions:-

1.
Initial PV is below the setpoint and, therefore, approaches the setpoint from below for a heat/cool control loop
2.
Initial PV is below the setpoint and, therefore, approaches the setpoint from below for a heat only control loop
3.
Initial PV is at the same value as the setpoint. That is, within 0.3% of the range of the controller if ‘PB.UNT’ is
set to ‘percent’ or +1 engineering unit (1 in 1000) if the ‘PB.UNT’ is set to ‘Eng’. Range is defined as ‘Range
High Limit’ to ‘Range Low Limit’ for process inputs or the range defined in section 8.1 for temperature inputs.
If the PV is just outside the range stated above the autotune will attempt a tune from above or below SP.
If the controller is autotuning and sensor break occurs, the autotune will abort. Autotune must be re-started when
the sensor break condition is no longer present.
If an Autotune cannot be performed an error message, Etun, will be flashed in the display

Autotune from Below SP – Heat/Cool
The point at which Automatic tuning is performed (Tune Control Point) is designed to operate just below the setpoint at
which the process is normally expected to operate (Target Setpoint). This is to ensure that the process is not significantly
overheated or overcooled. The Tune Control Point is calculated as follows:Tune Control Point = Initial PV + 0.75(Target Setpoint – Initial PV).
The Initial PV is the PV measured at ‘B’ (after a 1 minute settling period)
Examples: If Target Setpoint = 500OC and Initial PV = 20OC, then the Tune Control Point will be 380OC.
If Target Setpoint = 500OC and Initial PV = 400OC, then the Tune Control Point will be 475OC.
This is because the overshoot is likely to be less as the process temperature is already getting close to the target setpoint.
The sequence of operation for a tune from below setpoint for a heat/cool control loop is described below:-

‘CBLO’ is calculated on the basis of the size of this overshoot (assuming it is not set to Auto in the initial conditions).

Two cycles of oscillation are produced from which the peak to peak response and the true period of oscillation are
measured. PID terms are calculated
F to G
An extra heat stage is provided and all heating and cooling power is turned off at G allowing the plant to respond
naturally.
Measurements made during this period allow the relative cool gain ‘R2G’ to be calculated.
‘CBHI’ is calculated from CBLO*R2G.

Autotune is turned off at and the process is allowed to control at the target setpoint using the new control terms.
Autotune can also occur when the initial PV is above SP. The sequence is the same as tuning from below setpoint except
that the sequence begins with full cooling applied at ‘B’ after the first one minute settling time.

A test is done at the start of autotune to establish the conditions for a tune at setpoint.
The conditions are that the SP must remain within 0.3% of the range of the controller if ‘PB.UNt’ is set to
‘Percent’. If ‘PB.UNT’ is set to ‘Eng’ then the SP must remain within +1 engineering unit (1 in 1000). Range is
defined as ‘RNG.HI’ – ‘RNG.LO’ for process inputs or the range defined in section 0 for temperature inputs.
A to B
The output is frozen at the current value for one minute and the conditions are continuously monitored during
this period. If the conditions are met during this period autotune at setpoint is initiated at B. If at any time
during this period the PV drifts outside the condition limits a tune at setpoint is abandoned. Tuning is then
resumed as a tune from above or below setpoint depending on which way the PV has drifted.
Since the loop is already at setpoint there is no need to calculate a Tune Control Setpoint – the loop is forced to
oscillate around the Target Setpoint
C to G
Initiate oscillation - the process is forced to oscillate by switching the output between the output limits. From
this the period of oscillation and the peak to peak response is measured. PID terms are calculated
G to H
An extra heat stage is provided and all heating and cooling power is turned off at H allowing the plant to respond
naturally.
Measurements made during this period allow the relative cool gain ‘R2G’ to be calculated.

Autotune is turned off and the process is allowed to control at the target setpoint using the new control terms.
For a tune at setpoint autotune does not calculate cutback since there was no initial start up response to the application
of heating or cooling. The exception is that the cutback values will never be returned less than 1.6*PB.

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.
Adjust the setpoint to its normal running conditions (it is assumed this will be above the PV so that heat only is applied)
Set the Integral Time ‘TI’ and the Derivative Time ‘TD’ to ‘OFF’.
Set High Cutback ‘CBHI’ and Low Cutback ‘CBLO’ to ‘Auto’.
Ignore the fact that the PV may not settle precisely at the setpoint.
If the PV is stable, reduce the proportional band so that the PV just starts to oscillate. Allow enough time between each
adjustment for the loop to stabilise. Make a note of the proportional band value ‘PB’ and the period of oscillation ‘T’. If
PV is already oscillating measure the period of oscillation ‘T’, then increase the proportional band until it just stops
oscillating. Make a note of the value of the proportional band at this point.
Set the proportional band, integral time and derivative time parameter values according to the calculations given in the
table below:Type of control

Manually Setting the Cutback Values
Enter the PID terms calculated from the table in section 11.3.8 before setting 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 PV, then manually set the cutback parameters.
Proceed as follows:
Initially set the cutback values to one proportional bandwidth converted into display units. This can be calculated by
taking the value in percentage that has been installed into the parameter ‘PB’ and entering it into the following formula:PB/100 * Span of controller = Cutback High and Cutback Low
For example, if PB = 10% and the span of the controller is 0 -1200OC, then
Cutback High and Low = 10/100 * 1200 = 120
If overshoot is observed following the correct settings of the PID terms increase the value of ‘CBLO’ by the value of the
overshoot in display units. If undershoot is observed increase the value of the parameter ‘CBHI’ by the value of the
undershoot in display units.

Auto-tune Configures R2G
In a system which controls both heating and cooling the parameter R2G sets the cooling proportional band to
compensate for differences between the power available to heat, and that available to cool a process, see section 11.2.4.
There are certain load conditions where auto-tune may set an incorrect value for R2G. This will be seen as instability in
the control of the process after an auto-tune has been completed. In these circumstances check the value of R2G. If it is
low (approaching 0.1) AND the process is unstable it is necessary to manually determine a value of R2G and enter this
before carrying out a second auto-tune.
Note: it is only necessary to do this if the process causes the condition described above.
A parameter has been added (in 3200 controllers supplied after Dec 08) which provides the option to suppress the auto
tuning of R2G allowing it to be set manually. The parameter is called AT.R2G (Auto-tune R2G) and may be set to YES or
NO. YES is the default which means that R2G will be set automatically. NO requires a value for R2G to be entered
manually.
The sequence is as follows:1) Set AT.R2G to NO.
2) Enter a value for R2G. See the example below.
3) Calculate and enter a value for the TUNE LOW LIMIT from ‘OP.LO’ = -OP.HI x R2G. See Note 2.
4) Start Auto-tune
Example - To establish a value for R2G.
One way to approximate a suitable value for R2G is to measure the heating and cooling rates around the normal
operating temperature of the system.
1) Measure the heating and cooling rates of the process:a) Put the controller into Manual mode and turn heating power ON (limited by OP.HI).
b) Allow the process to heat from below normal operating setpoint and for the actual temperature to pass
through the normal operating setpoint. When the actual temperature is (say 10%) above normal working
temperature turn off the heat.
c) Allow the temperature to settle then turn cooling power ON (limited by OP.LO). Allow the temperature to
fall below normal working setpoint.
A graphical example of the results is shown below:OP.HI
Heating power on
Temperature
Cooling rate ‘C’
Normal operating setpoint
OP.LO
Heating rate ‘H’
Cooling power on
2) Calculate R2G from R2G = (H/C) * (OP.LO/OP.HI)
For example Heating rate ‘H’ = 10oC per minute, Cooling rate ‘C’ = 25 oC per minute, OP.HI = 80%, OP.LO = 40% then
R2G = 0.2
Enter a value of 0.2 for R2G
Note 1: This calculation will compensate for the different output limits set by OP.HI and OP.LO.
Note 2: If the calculated value for TU.LO is greater than the output limit set by OP.LO, continue to enter the calculated
value.
Note 3: It is envisaged that this procedure would normally be carried out by the equipment manufacturer. However,
once the value of R2G has been determined and AT.R2G has been set to NO, autotuning your process from then on can
be repeated by simply selecting ATUNE = On (assuming, of course, that the characteristics of the process have not
changed significantly).

Effect of Control Action, Hysteresis and Deadband
For temperature control ‘CONTROL ACTION’ will be set to ‘rev’. For a PID controller this means that the heater power
decreases as the PV increases. For an on/off controller output 1 (usually heat) will be on (100%) when PV is below the
setpoint and output 2 (usually cool) will be on when PV is above the setpoint
Hysteresis applies to on/off control only. It defines the difference in temperature between the output switching off and
switching back on again. The examples below show the effect in a heat/cool controller.
Deadband can operate on both on/off control or PID control where it has the effect of widening the period when no
heating or cooling is applied. However, in PID control its effect is modified by both the integral and derivative terms.
Deadband might be used in PID control, for example, where actuators take time to complete their cycle thus ensuring
that heating and cooling are not being applied at the same time. Deadband is likely to be used, therefore, in on/off
control only. The second example below adds a deadband of 20 to the above example.
In an on/off controller, if CONTROL ACTION = rev then OP2 will be on when PV is below SP. OP1 will be on when the PV
is above SP. The outputs are, therefore, reversed in the above example.

Alarms are used to alert an operator when a pre-set level has been exceeded. They are indicated by a scrolling message
on the display and the red ALM beacon. They may also switch an output– usually a relay (see section 12.1.1) – to allow
external devices to be operated when an alarm occurs. Alarms only operate if they have been ordered and configured.
Up to eight different alarms are available:-
•
Alarm 1: configurable as full scale high or low, band or deviation high or low
•
Alarm 2: configurable as full scale high or low, band or deviation high or low
•
Alarm 3: configurable as full scale high or low, band or deviation high or low
•
Alarm 4: configurable as full scale high or low, band or deviation high or low
•
Sensor Fault alarm. An alarm condition - INPUT SENSOR BROKEN (S.br) is indicated if the sensor or the wiring
between sensor and controller becomes open circuit. The output level will adopt a ‘SAFE’ value which can be set up
in Operator Level 2, see section 11.2.
•
For a PRT input, sensor break is indicated if any one of the three wires is broken.
For mA input sensor break will not be detected due to the load resistor connected across the input terminals.
For Volts input sensor break may not be detected due to the potential divider network connected across the input
terminals.
•
Loop Break alarm. Displayed as CONTROL LOOP BROKEN. This occurs if the controller does not detect a change in
process value following a change in output demand after a suitable delay time.

ALM beacon does not light but an output associated with this parameter will
activate. A scrolling message may be configured using iTools, as described in
section 17.7. If a message has been configured it will scroll across the display
while the event is true.
The alarm may be masked during start up. Blocking prevents the alarm from being activated until the
process has first achieved a safe state. It is used to ignore start up conditions which are not representative
of running conditions.
A blocking alarm is re-initiated after a setpoint change.
See section 12.2 for an explanation of the behaviour of blocking alarms under different conditions.

Behaviour of Alarms After a Power
The response of an alarm after a power cycle depends
upon the latching type, whether it has been configured
to be a blocking alarm, it's state and the acknowledge
status of the alarm.
The response of active alarms after a power cycle is as
follows:
For a non-latching alarm or an event alarm blocking will
be re-instated, if configured. If blocking is not
configured the active alarm will remain active. If the
alarm condition has gone safe during the down time the
alarm will return inactive.
For an auto-latching alarm blocking will be re-instated, if
configured, only if the alarm had been acknowledged
prior to the power cycle. If blocking is not configured or
the alarm had not been acknowledged the active alarm
will remain active. If the alarm condition has gone safe
during the downtime the alarm will return inactive if it
had been acknowledged prior to the power cycle else it
will return safe but not acknowledged. If the alarm was
safe but not acknowledged prior to the power cycle the
alarm will return safe but not acknowledged.
For a manual-latching alarm blocking will not be reinstated and the active alarm will remain active. If the
alarm condition has gone safe during the downtime the
alarm will return safe but not acknowledged. If the
alarm was safe but not acknowledged prior to the power
cycle the alarm will return safe but not acknowledged.

Programmer
This section describes configuration of all features of the programmer.
Function code CP is an eight segment programmer consisting of four ramp/dwell pairs. Each ramp consists of a
controlled rate of change of setpoint to a target level. Each ramp is followed by a dwell at that level. The ramp rate,
target level and dwell time can also be set by the user in Level 2 and is described in section 5.9.1.

Run/End Digital Outputs
Digital outputs (normally relay) may be made to operate while the program is in Run mode or End mode, as shown in the
diagram in section 13.2. These outputs are set up in configuration level by selecting the appropriate output parameter list
- IO-1, OP-2, OP-3, or AA and assigning the parameter ‘PrG.E’ to the ‘SRC.A’ (B, C, or D) parameter.
The following example describes how to configure OP-2 to operate when the programmer is running and OP-3 to operate
when the programme is complete. It is assumed that IO-1 is configured as the control output for a heat only controller.

Event Output During a Segment
This feature was added after software version 2.
A digital event may be configured to operate in any segment of the program. This is set up in the TIMER List by the
parameter ‘EVENT’.
To turn an output on in a segment, use the table and diagram, below to obtain the weighting value for that segment.
Note down the weightings for each segment in which the output is to be turned on and add them together. Set the
Event Settings value to this number.
For example, to switch an output on in the first ramp segment and the second dwell, the weightings would be 1 and 8.
So the Event Setting would be 9. To turn the event on in Ramp 1 and Dwell 3 the weightings would be 1 and 32, so the
event setting would be 33. To turn the event on in Dwell 1, Dwell 3 and Dwell 4 the weightings would be 2 + 32 + 128 =
162. This is shown in the diagram below.
See also the example ‘To Configure the Programmer’ section 13.2.4.

Resolution defines how the Dwell time is displayed
when the programmer is running. It does not set the
dwell or ramp rate. Ramp Rate must be set in Level 3
or Configuration level by the ‘RampUnits’ parameter
found in the ‘SP’ List, see section 10.1.
In this example the dwell periods will not start until
the PV is within 5 units of the setpoint
In this example the controller will continue to control
indefinitely at the last setpoint.
OFF will turn the output power off and SP2 will
control at setpoint 2
In this example the program will start from the
current value of the process variable
In this example the setpoint will ramp from the
current value of the PV to the first target - 100
In this example the setpoint will ramp to 100 at 8.0
units per hour. The ramp units are set up in the

15. Digital Communications
15.1.2
Digital Communications (or ‘comms’ for short) allows
the controller to communicate with a PC or a
networked computer system.
To use EIA485, buffer the EIA232 port of the PC with a
suitable EIA232/EIA485 converter. The Eurotherm
Controls KD485 Communications Adapter unit is
recommended for this purpose. The use of a EIA485
board built into the computer is not recommended
since this board may not be isolated, which may cause
noise problems, and the RX terminals may not be biased
correctly for this application.
This product conforms to MODBUS RTU protocol a full
description of which can be found on www.modbus.org.
Two ports are available both using MODBUS RTU
communication facilities:
1.
A configuration port - intended to communicate
with a system to download the instrument
parameters and to perform manufacturing tests
and calibration
2.
An optional EIA232 or EIA485 port on terminals HD,
HE and HF - intended for field communications
using, for example, a PC running a SCADA package.
The two interfaces cannot operate at the same time.
For a full description of digital communications
protocols (Modbus RTU) refer to the 2000 series
Communications Handbook, part number HA026230,
available on www.eurotherm.co.uk.
EIA485 (2-wire)
To construct a cable for EIA485 operation use a
screened cable with one (EIA485) twisted pair plus a
separate core for common. Although common or
screen connections are not necessary, their use will
significantly improve noise immunity.

To use EIA422, buffer the EIA232 port of the PC with
a suitable EIA232/EIA422 converter. The KD485
Communications Converter unit is recommended for
this purpose. Instruments on a EIA422
communication network should be chain connected
and not star connected.
To construct a cable for EIA422 operation use a

Broadcast Communications
Broadcast communications as a simple master is available
on 3200 controllers from software versions 1.10 or
greater. Broadcast master communications allows the
3200 controller to send a single value to any number of
slave instruments. Modbus broadcast using function
code 6 (Write single value) must be used. This allows the
3200 to link with other products, without the need for a
supervisory PC, to create a small system solution.
Example applications include multi-zone setpoint
programming applications or cascade control using a
second controller. The facility provides a simple and
precise alternative to analogue retransmission.
15.2.3

Broadcast Master Communications
The 3200 broadcast master can be connected to up to 31
slaves if no segment repeaters are used. If repeaters are
used to provide additional segments, 32 slaves are
permitted in each new segment. The master is
configured by setting the ‘RETRN’ parameter to W.SP, PV,

If iTools, or any other Modbus master, is connected
to the port on which the broadcast master is
enabled, then the broadcast is temporarily inhibited.
It will restart approximately 30 seconds after iTools
is removed. This is to allow reconfiguration of the
instrument using iTools even when broadcast master

Alarms and other Status Changes
15.3
EEPROM Write Cycles
!
Warning
In common with most instruments in its class, the
3200 Range uses a non-volatile memory with a
limited number of specified writes. Non-volatile
memory is used to hold information that must be
retained over a power cycle. Typically, this includes
setpoint and status information, including alarm
latch status.
Please ensure that parameters which do not require
updating on a regular basis (for example, setpoints,
alarm trip levels, hysteresis, etc) are only written to
when a change in the parameter value occurs.
Failure to do this could result in permanent damage
to the internal EEPROM.
When using the 3200 range, use the ‘AltSP’ variable
at Modbus address 26, which has no write
restrictions, if you need to write to a temperature
setpoint. A local trim value may also be applied
using the ‘SPTrim’ parameter at Modbus address 27.
Some examples of parameters which could cause this
limit to be exceeded over a period of time are given
below.
Setpoint Ramping
Continuous changing of setpoint via digital
communications – for example a ramping value – is the
most common cause of EEPROM wear.
Alarm status is saved in non-volatile memory and this
includes status alarms such as sensor break, loop break,
remote fail and individual alarm and alarm latching
status. Every transition into and out of an alarm
condition triggers an EEPROM write. Thus, if there is any
fast toggling of an alarm status, EEPROM wear can result
within the expected lifetime of an instrument.
An example of this is where event alarms are used to
provide an on/off control loop. 3200 instruments should
on no account be used in this manner since the toggling
of the output will rapidly use up the 100,000 writes. The
On/Off control in the PID algorithm should be used
instead. However, any situation where alarm states can
change rapidly should be avoided.
Mode and Timer/Programmer Changes
Rapid changes to instrument mode (Auto/Manual) or the
Timer/Programmer operation can cause EEPROM wear
because the status (run/hold/reset) or the segment
number are stored in EEPROM on each transition.
In normal use where segments or timer sequences are
relatively long, it is unlikely that problems will be seen.
However, in some applications where a sequence is run
frequently, EEPROM wear will occur. An example of this
is where a digital input is used in an application to trigger
a timer sequence and the operation is performed as fast
as possible by the operator.
Digital Inputs
One solution, as stated above, is to enable the “Alternate
Setpoint” (address 276), then write values directly to the
“Alternate Setpoint, AltSP” (address 26). These
parameters may be found in the SP list in iTools and are
L-R and REM.SP in the controller. Note that an
approximately 5 second timeout is applied to writes to
Modbus address 26. This, therefore requires regular
updating which, for setpoint ramping, is ideally suited.
Care should be taken with any rapid cycling digital
inputs. Typically a digital input triggering timer or mode
changes (as above) should be carefully considered so
that they do not switch more than 100,000 times during
the expected lifetime of the instrument.
In other applications where regular updating may not be
ideal, this may be avoided by writing to the “Target
Setpoint” at address 02. The Alternate Setpoint must
also be enabled at address 276. The value written to
address 02 will then be written permanently to address
26. Note, however, that any value written to the Target
Setpoint will not be retained over a power fail since the
controller then reverts to the setpoint selected (for
example, SP1 or SP2).
.
It is critically important to select the Alternate Setpoint
if updating the setpoint on a regular basis otherwise the
setpoint change will be saved to non-volatile memory
and EEPROM wear will result.

DATA ENCODING

Note that the Eurotherm iTools OPC server provides
a straightforward means of accessing any variable in the
3200 controller in the correct data format without the
need to consider data representation. However if you
wish to write your own communications interface
software, you will need to take the format used by the
3200 comms software into account.
Modbus data is normally encoded into a 16 bit signed
integer representation.

For further information see 2000 Series Communications
Handbook Part No. HA026230.
Integer format data, including any value without a
decimal point or represented by a textual value (for
example ‘off’, or ‘on’), is sent as a simple integer value.
For floating point data, the value is represented as a
‘scaled integer’, in which the value is sent as an integer
which gives the result of the value multiplied by 10 to
the power of the decimal resolution for that value. This
is easiest to understand by reference to examples:

It may be necessary for the Modbus master to insert or
remove a decimal point when using these values.
It is possible to read floating point data in a native 32 bit
IEEE format. This is described in the Eurotherm Series
2000 Communications Handbook (HA026230), Chapter 7.
For time data, for example, the length of a dwell, the
integer representation depends on the resolution. For
‘hours’ resolution, the value returned is the number of
minutes the value represents, so for example a value of
2:03 (2 hours and three minutes) would be returned as
an integer value of 123. For ‘minutes’ resolution, the
value used is the number of seconds the value
represents, so that 12:09 (12 minutes and 9 seconds)
would be returned as 729.
It is possible to read time data in a native 32 bit integer
format, in which case it returns the number of
milliseconds the variable represents regardless of the
resolution. This is described in the Eurotherm Series
2000 Communications Handbook (HA026230), Chapter 7.

16. Calibration
16.1.2
The controller is calibrated during manufacture using
traceable standards for every input range. It is,
therefore, not necessary to calibrate the controller when
changing ranges. Furthermore, the use of a continuous
automatic zero correction of the input ensures that the
calibration of the instrument is optimised during normal
operation.
The input may have been configured for a process input
of mV, Volts or mA and scaled in Level 3 as described in
section 8.3. The example described in section 8.3.1
assumes that the display is set up to read 2.0 for an input
of 4.000mV and 500.0 for an input of 20.000mV.
To comply with statutory procedures such as the Heat
Treatment Specification AMS2750, the calibration of the
instrument can be verified and re-calibrated if
considered necessary in accordance with the instructions
given in this chapter.
To Check mV Input Calibration
To check this scaling, connect a milli-volt source,
traceable to national standards, to terminals V+ and Vusing copper cable as shown in the diagram below.
Controller VI
V+
V-
+
Copper cable

Source
-
For example AMS2750 states:- "Instructions for
calibration and recalibration of "field test
instrumentation" and "control monitoring and recording
instrumentation" as defined by the NADCAP Aerospace
Material Specification for pyrometry AMS2750D clause
3.2.5 (3.2.5.3 and sub clauses), including Instruction for
the application and removal of offsets defined in clause
3.2.4.”
☺
16.1
Set the mV source to 20.000mV. Check the display reads
500.0 +0.25% + 1LSD.
To Check Input Calibration
The PV Input may be configured as mV, mA,
thermocouple or platinum resistance thermometer.
16.1.1
Precautions
Before checking or starting any calibration procedure the
following precautions should be taken:1.
2.
3.
When calibrating mV inputs make sure that the
calibrating source output is set to less than
250mV before connecting it to the mV
terminals. If accidentally a large potential is
applied (even for less than 1 second), then at
least one hour should elapse before
commencing the calibration.
RTD and CJC calibration must not be carried
out without prior mV calibration.
A pre-wired jig built using a spare instrument
sleeve may help to speed up the calibration
procedure especially if a number of instruments
are to be calibrated.
4.
Power should be turned on only after the
controller has been inserted in the sleeve of the
pre-wired circuit. Power should also be turned
off before removing the controller from its
sleeve.
5.
Allow at least 10 minutes for the controller to
warm up after switch on.
Figure 1: Connections for mV Input Calibration
Ensure that no offsets (see sections 8.2.1 and 16.2)
have been set in the controller.
Set the mV source to 4.000mV. Check the display reads
2.0 +0.25% + 1LSD (least significant digit).
16.1.3
To Check Thermocouple Input
Calibration
Connect a milli-volt source, traceable to national
standards, to terminals V+ and V- as shown in the

Adjust the mV source for to the minimum range. For a
type J thermocouple, for example, the minimum range is
-210OC. However, if it has been restricted using the
Range Low parameter then set the mV source to this
limit. Check that the reading on the display is within

To Check RTD Input Calibration
Connect a decade box with total resistance lower than
1K and resolution to two decimal places in place of the
RTD as indicated on the connection diagram below
before the instrument is powered up. If at any instant
the instrument was powered up without this connection
then at least 10 minutes must elapse from the time of
restoring this connection before RTD calibration check
can take place.

16.2 Offsets
The process value can be offset to take into account
known errors within the process. The offset can be
applied to any Input Type (mV, V, mA, thermocouple or
RTD).
A single offset can be applied - the procedure is carried
out in the I N P U T list and has been described in section
8.2.
It is also possible to adjust the low and high points as a
two point offset. This can only be done in Level 3 in the
‘C a l ’ list and is described below.

Figure -3: Connections for RTD Calibration
The RTD range of the instrument is -200 to 850OC. It is,
however, unlikely that it will be necessary to check the
instrument over this full range.
Set the resistance of the decade box to the minimum
range. For example 0OC = 100.00Ω. Check the
calibration is within +0.25% of reading + 1LSD.
Two Point Offset
A two point offset adjusts both a low point and a high
point and applies a straight line between them. Any
readings above and below the 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 as shown in the example below:Display

16.3 Input Calibration
If the calibration is not within the specified accuracy follow the procedures in this section:In 3200 series instruments, inputs which can be calibrated are:•
mV Input. This is a linear 80mV range calibrated at two fixed points. This should always be done before calibrating
either thermocouple or resistance thermometer inputs. mA range calibration is included in the mV range.
•
Thermocouple calibration involves calibrating the temperature offset of the CJC sensor only. Other aspects of
thermocouple calibration are also included in mV calibration.
•
Resistance Thermometer. This is also carried out at two fixed points - 150Ω and 400Ω.
16.3.1
To Calibrate mV Input
Calibration can only be carried out in configuration level.
Calibration of the mV range is carried out using a 50 milli-volt source, connected as described in section 16.1.2. mA
calibration is included in this procedure.
For best results 0mV should be calibrated by disconnecting the copper wires from the mV source and short circuiting the
input to the controller

17. Configuration Using iTools
17.2.2
iTools is a configuration and monitoring package which
will edit, store and ‘clone’ complete controller
configurations.
A Configuration Clip is available with iTools by quoting
part number 3000CK in the iTools ordering code. The
clip can be fitted into the side of a controller as shown
below. The controller remain fitted or removed from
its sleeve.
iTools can be used to configure all the functions of
3200 series controllers described in this manual. It is
also possible using iTools to configure additional
functions such as customised messages and parameter
promotion. These features are described in this
chapter.
Configuration Clip
You may also wish to refer to the iTools Help Manual
Part No. HA028838. This can be downloaded from
www.eurotherm.co.uk. A provides further information
on how to install, connect and generally operate iTools.
17.1 Loading an IDM
An IDM is a software file which defines the parameter
addresses of a particular build of instrument. This is
normally included with your iTools CD and iTools will
then recognize the software version of your instrument.
Alternatively, download the latest version of iTools.
This may be found in www.eurotherm.co.uk.
If the build of your instrument is a non-standard, it may
be necessary for you to download the IDM from the
Eurotherm web site. The file will be of the format
id32i_v107.exe, where id 32i is the instrument and V--is the software version number of the instrument.
The benefit of using this arrangement is that it is not
necessary to power the controller, since the clip
provides the power to the internal memory of the
controller.
To load the IDM
From windows START, select Programs → Eurotherm
iTools → Advanced Tools → IDM Manager. Then Install
New IDM.
To register the new IDM
Copy the file to c:\Program
Files\Eurotherm\iTools\Devices.

Connecting a PC to the Controller
In 3200 series controllers this may be done using digital

Cloning
The cloning feature allows the configuration and parameter settings of one instrument to be copied into another.
Alternatively a configuration may be saved to file and this used to download to connected instruments. The feature
allows new instruments to be rapidly set up using a known reference source or standard instrument. Every parameter and
parameter value is downloaded to the new instrument which means that if the new instrument is used as a replacement it
will contain exactly the same information as the original. Cloning is generally only possible if the following applies:
•
The target instrument has the same hardware configuration as the source instrument
•
The target instrument firmware (i.e. Software built into the instrument) is the same as or a later version than that of
the source instrument. The instrument firmware version is displayed on the instrument when power is applied.
•
Generally, cloning will copy all operational, engineering and configuration parameters that are writable. The
communications address is not copied.
Every effort has been made to ensure that the information contained within the clone files is a replica of that configured
in the instrument. It is the users responsibility to ensure that the information cloned from one instrument to another is
correct for the process to be controlled, and that all parameters are correctly replicated into the target instrument.
Below is a brief description of how to use this feature. Further details are available in the iTools Handbook.
17.12.1
Save to File
The configuration of the controller made in the previous sections may be saved as a clone file. This file can then be used
to download the configuration to further instruments.
From the File menu use ‘Save to File’ or use the ‘Save’ button on the Toolbar.
17.12.2
To Clone a New Controller
Connect the new controller to iTools and Scan to find this instrument as described at the beginning of this chapter.
From the File menu select ‘Load Values From File’ or select ‘Load’ from the toolbar. Choose the required file and follow
the instruction. The new instrument will be configured to this file.
