* 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’, supplied in the accessory kit, 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, 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.

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
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, (refer to accompanying documents)
Equipment protected throughout by DOUBLE
INSULATION

15
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 for use in 240Vac CAT II.
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
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.

16
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;

17
• 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.

18
4. Switch On
A brief start up sequence consists of a self test in
which all elements of the display are illuminated and
the software version is shown. What happens next
depends on one of two conditions;-
1. The instrument is new and has been supplied
un-configured (go to section 4.1)
2. The instrument has been supplied configured
in accordance with the Quick Start code (go to
section 4.3)
4.1 Initial Configuration
If the controller has not previously been configured
it will start up showing the ‘Quick Configuration’
codes. This is a built in tool which enables you to
configure the input type and range, the output
functions and the display format.
The quick code consists of a ‘SET’ of five
characters. The upper section of the
display shows the set selected (in the
case of 3116 SET 1 only), the lower
section shows the five digits which
make up the set. Adjust these as follows:-
1. Press any button.The first character will
change to a flashing ‘-‘.
2. Press
▲or ▼to change the flashing
character to the required code shown in the
quick code tables –see next page. Note: An
xindicates that the option is not fitted.
3. Press
!to scroll to the next character. If
you need to return to the first character press
!.
When the last digit has been entered press !
again, the display will show
Press ▲or ▼to .
The controller will then automatically go to the
operator level.
