1. Installation and Basic Operation
1.1 What Instrument Do I Have?
Thank you for choosing this 3200 series Temperature
Controller/Programmer.
The 3200 series provide precise temperature control of
industrial processes and is available in three standard
DIN sizes:-
•1/16 DIN Model Number 3216
•1/8 DIN Model Number 3208
•1/8 DIN Horizontal Model Number 32h8
•1/4 DIN Model Number 3204
A universal input accepts various thermocouples, RTDs or
process inputs. Up to three (3216) or four (3208, 32h8
and 3204) outputs can be configured for control, alarm
or re-transmission purposes. Digital communications and
a current transformer input are available as options.
The controller may have been ordered to a hardware
code only or pre-configured using an optional ‘Quick
Start’ code.
The label fitted to the side of the sleeve shows the
ordering code that the controller was supplied to.
The last two sets of five digits show the Quick Start Code.
If the Quick Start Code shows *****/***** the controller
was supplied with default parameters and will need to be
configured when it is first switched on.
This Manual takes you through all aspects of installation,
wiring, configuration and use of the controller.
1.2 Unpacking Your Controller
The controller is supplied with:-
•Sleeve (with the controller fitted in the sleeve)
•Two panel retaining clips and IP65 sealing gasket
mounted on the sleeve
•Component packet containing a snubber for each
relay output (see section 2.11) and a 2.49Ωresistor
for current inputs (see section 2.6)
•Installation sheet Part Number HA029714

the ambient temperature is within 0 and 55oC (32 -
131oF) and humidity 5 to 95% RH non condensing.
The instrument can be mounted on a panel up to 15mm
thick.
To ensure IP65 and NEMA 4 front protection, mount on
a non-textured surface.
Please read the safety information in section 3 before
proceeding. The EMC Booklet part number HA025464
gives further installation information.
1.4.1 Panel Mounting the Controller
1. Prepare a cut-out in the mounting panel to the size
shown. If a number of controllers are to be mounted
in the same panel observe the minimum spacing
shown.
2. Fit the IP65 sealing gasket behind the front bezel of
the controller
3. Insert the controller through the cut-out
4. Spring the panel retaining clips into place. Secure
the controller in position by holding it level and
pushing both retaining clips forward.
5. Peel off the protective cover from the display.

2.4 Wire Sizes
The screw terminals accept wire sizes from 0.5 to 1.5 mm
(16 to 22AWG). Hinged covers prevent hands or metal
making accidental contact with live wires. The rear
terminal screws should be tightened to 0.4Nm (3.5lb in).
2.5 Precautions
•Do not run input wires together with power cables
•When shielded cable is used, it should be grounded
at one point only
•Any external components (such as zener barriers,
etc) connected between sensor and input terminals
may cause errors in measurement due to excessive
and/or un-balanced line resistance or possible
leakage currents
•Not isolated from the logic outputs & digital inputs
•Pay attention to line resistance; a high line resistance
may cause measurement errors

2.11 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.
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.
2.12 Digital Inputs A & B
Digital input A is an optional input in all 3200 series
controllers.Digital input B is always fitted in models
3208, 32h8 and 3204, but is not available in 3216.
•Not isolated from the current transformer input or
the sensor input
•Switching: 12Vdc at 40mA max
•Contact open > 500Ω. Contact closed < 200Ω
•Input functions: Please refer to the list in the quick
codes.
☺If EIA232 digital communications is fitted (3216
only), Digital Input A is not available.
2.13 Current Transformer
The current transformer input is an optional input in all
3200 series controllers.
☺If EIA232 digital communications is fitted (3216
only), Current Transformer Input is not available.
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.
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.
2.14 Transmitter Power Supply
The Transmitter Supply is not available in the Model
3216. It is fitted as standard in the Models 3208, 32h8
and 3204.
•Isolated output 240Vac CAT II
•Output: 24Vdc, +/- 10%. 28mA max.

2.15.1.1 EIA422 Connections (3216 only)
☺If EIA422 serial communications is fitted, the CT and
LA digital input option is not possible since EIA422 shares
the same terminals as the CT and LA.
☺The KD485 communications converter is
recommended for:
•Interfacing 4-wire to 2-wire connections.
•To buffer an EIA422/485 network when more than
32 instruments on the same bus are required
•To bridge 2-wire EIA485 to 4-wire EIA422.

3. Safety and EMC Information
This controller is intended for industrial temperature and
process control applications when it will meet the
requirements of the European Directives on Safety and
EMC. Use in other applications, or failure to observe the
installation instructions of this handbook may impair
safety or EMC. The installer must ensure the safety and
EMC of any particular installation.
Safety
This controller complies with the European Low Voltage
Directive 73/23/EEC, by the application of the safety
standard EN 61010.
Electromagnetic compatibility
This controller conforms with the essential protection
requirements of the EMC Directive 89/336/EEC, 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.
SERVICE AND REPAIR
This controller has no user serviceable parts. Contact
your supplier 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.
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.
3.1 Installation Safety Requirements
Safety Symbols
Various symbols may be used on the controller. They
have the following meaning:
☺Helpful hints
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.
Caution: Live sensors
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.
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.
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.
!Caution, (refer to
accompanying documents)
Equipment protected
throughout by DOUBLE
INSULATION

3200 Series
16 Part No HA028651 Issue 7.0 Apr-09
Voltage rating
The maximum continuous voltage applied between any
of the following terminals must not exceed 264Vac:
•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 264Vac 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.
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:
•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:
•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.
For typical applications we recommend Schaffner
FN321 or FN612.
•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. We
recommend Schaffner types FN321 and FN612.
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.

4.2 To Re-Enter Quick Code mode
If you need to re-enter the ‘Quick Configuration’ mode
this can always be done as follows:-
1. Power down the controller
2. Hold down the button, and power up the
controller again.
3. Keep the button pressed until code is displayed.
4. Enter the configuration code (this is defaulted to 4
in a new controller)
5. The quick start codes may then be set as described
previously
☺Parameters may also be configured using a deeper
level of access. This is described in later chapters of this
handbook.
☺If the controller is started with the button held
down, as described above, and the quick start codes are
shown with dots (e.g. J.C.X.X.X), this indicates that the
controller has been re-configured in a deeper level of
access and, therefore, the quick start codes may not be
valid. If the quick start codes are accepted by scrolling
to then the quick start codes are reinstated.
4.3 Pre-Configured Controller or
Subsequent Starts
A brief start up sequence consists of a self test during
which the software version number is shown followed
briefly by the quick start codes.
It will then proceed to Operator Level 1..
You will see the display shown below. It is called the
HOME display.
☺If the quick start codes do not appear during this
start up, it means that the controller has been configured
in a deeper level of access, see the note in section 4.2.
The quick start codes may then not be valid and are
therefore not shown.
