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
• 1/4 DIN Model Number 3204
A universal input accepts various thermocouples, RTDs or
process inputs. Up to three (3216) or four (3208 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 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 2.9) and a 2.49Ωresistor for current
inputs (see section 2.5)

* 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.
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.
2.9 Digital Inputs A & B
Digital input A is an optional input in all 3200 series
controllers. It is not available in 3116. Digital input B is
always fitted in models 3208 and 3204, but is not available in
3116 or 3216.
• Not isolated from 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.
2.10 Current Transformer
The current transformer input is an optional input in all 3200
series controllers. It is not available in 3116.
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 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.

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.
2.16 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.
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.
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 categoryII, 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.

3.2 To Re-Enter Quick Code mode
If you need to re-enter the ‘Quick Configuration’ mode this
can always be done by powering down the controller, holding
down the !button, and powering up the controller again.
You must then enter a passcode using the ▲or ▼
buttons. In a new controller the passcode defaults to 4. If an
incorrect passcode is entered you must repeat the whole
procedure.
Note- Parameters may also be configured using a deeper
level of access. This is described in subsequent chapters of
this handbook.
If parameters have been configured in this level then the
quick codes may not be valid and not shown.
3.3 Pre-Configured Controller or
Subsequent Starts
The controller will briefly display the quick codes during
start up and then proceed to operator level 1.
Note:- If the Quick Codes do not appear during start up this
means that the controller has been re-configured in a deeper
level of access, as stated above, and the Quick Codes may no
longer be valid.
The controller will power up in the mode it was in prior to
shutdown and you will see the display shown below. It is
called the HOME display.

3.4.3 Auto, Manual and Off Mode
The controller can be put into Auto, Manual or Off mode –
see next section.
Auto mode is the normal operation where the output is
adjusted automatically by the controller in response to
changes in the measured temperature.
Manual mode means that the controller output power is
manually set by the operator. The input sensor is still
connected and reading the temperature but the control loop
is ‘open’. In manual mode the MAN beacon will be lit. The
power output can be increased or decreased using the ▼or
▲buttons.
!Manual mode must be used with care. The power level
must not be set and left at a value that can damage the
process or cause over-heating. The use of a separate ‘over-
temperature’ controller is recommended.
Off mode means that the heating and cooling outputs are
turned off. The alarm outputs will, however, still be active.
