Installation and Basic Operation
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 Code. If the Quick Code shows *****/*****
the controller will need to be configured when it is
first switched on.
This User Guide takes you through step by step
instructions to help you to install, wire, configure and
use the controller. For features not covered in this
User Guide, a detailed Engineering Manual, Part No
HA027986, and other related handbooks can be
downloaded from www.eurotherm.co.uk.
1.1 Unpacking Your Controller

1.3 Step 1: Installation
This controller is intended for permanent
installation, for indoor use only, and enclosed in an
electrical panel
Select a location which is subject to minimum
vibrations, the ambient temperature is within 0 and
55oC (32 - 131oF) and humidity 5 to 95% RH non
condensing.
The controller can be mounted on a panel up to
15mm thick
To ensure IP65 and NEMA 4 front sealing against
dust and water, 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.
1.3.1 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 Sensor Input (Measuring Input)
•Do not run input wires with power cables
•When shielded cable is used, it should be grounded
at one point only
•Any external components (such as zener barriers)
connected between sensor and input terminals may
cause errors in measurement due to excessive and/or
un-balanced line resistance, or leakage currents.
•Not isolated from the logic outputs & digital inputs
Thermocouple Input
Positive
Negative
•Use the correct compensating cable preferably
shielded.
RTD Input
PRT
PRT
Lead compensation
•The resistance of the three wires must be the same.
The line resistance may cause errors if it exceeds
22Ω.
Linear mA, mV or Voltage Inputs
Positive
Negative
•For a mA input connect the 2.49Ωburden resistor
supplied between the V+ and V- terminals as shown
•For a 0-10Vdc input an external input adapter is
required (not supplied). Part number: SUB21/IV10.
With this adaptor fitted
sensor break alarm does not
operate.

2.7 Remote Setpoint Input
•There are two inputs; 4-
20mA and Volts which
can be fitted in place of
digital communications
•It is not necessary to fit
an external burden
resistor to the 4-20mA input
•If the 4-20mA remote setpoint input is connected
and valid (>3.5mA; < 22mA) it will be used as the
main setpoint. If it is not valid or not connected the
controller will try to use the Volts input. Volts
sensor break occurs at <-1; >+11V. The two inputs
are not isolated from each other
•If neither remote input is valid the controller will
fall back to the internal setpoint, SP1 or SP2 and
flash the alarm beacon. The alarm can also activate
a relay if configured or read over digital
communications. See Engineering Handbook
HA027986
•To calibrate the remote setpoint, if required, see the
Engineering Handbook HA027986
•A local SP trim value is available in a deeper level
of access. See Engineering Handbook HA027986
2.8 Output 3
Output 3 is not available in model 3216. In 1/8 and
1/4 DIN controllers it is either a relay or a mA output.
Relay Output (Form A, normally open)

•Contact rating: 2A 264Vac resistive
•Output functions: Heating, or cooling,
or alarm or motorised valve open or
closed

20mA
•Max load resistance: 500Ω
•Calibration accuracy: +(<0.25% of
reading + <50μA
•Output functions: Heating, or cooling, or

* General Notes 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, it 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.

2.10 Digital Inputs A & B
Digital input A is an optional input in all Model sizes.
Digital input B is always fitted in the Models 3208,
32h8 and 3204.

•Contact open > 500Ω. Contact closed < 200Ω
•Input functions: Please refer to the list in the
quick codes.
☺If EIA422 digital communications is fitted,

2.12 Current Transformer
The current transformer input is an optional input in
all model sizes.
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.
☺If EIA422 digital communications is fitted,
Current Transformer Input is not available.
Note: Terminal C 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.
