1.3 Step 1: Installation
This instrument is intended for permanent installation, for indoor use only, and enclosed in an electrical panel
Select a location which is subject to minimum vibrations and the ambient temperature is within 0 and 55oC (32 - 122oF)
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 4 before proceeding and refer to the EMC Booklet part number HA025464
for further installation information.
1.3.1 Panel Mounting the Controller
1. Prepare a square cut-out in the mounting panel to the size
shown. If a number of controllers are to be mounted in
the same panel they should be spaced as shown.
2. Fit the IP65 sealing gasket, if required, 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
1.3.2 To Remove the Controller from its Sleeve
The controller can be unplugged from its sleeve by easing the

3.2 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).
3.3 PV Input (Measuring Input)
1. Do not run input wires together with power cables
2. 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
3.3.1 Thermocouple Input
For thermocouple input use the correct compensating cable preferably shielded
3.3.2 RTD Input
The resistance of the three wires must be the same. The line resistance may cause errors if it is greater than 22Ω
3.3.3 Linear Input (mA or V)
A line resistance for voltage inputs may cause measurement errors
For volts input an external module is required. Input resistance 100KΩ.
For mA input connect burden resistor of 2.49Ωacross the + and - input as shown

3116 User Guide Part No. HA028005ENG Issue 2.0 May 04 ENG 9
3.4 Input/Output 1 (Relay or Logic)
This may be a logic input or a logic output or a relay output
Relay output normally open (Form A), 2A 264Vac resistive
OR
Logic output to drive SSR (not isolated)
Logic level On/High - 12Vdc at 5 to 40mA max
Logic level Off/Low - <100mV <100µA
OR
Digital Input (contact closure)
3.5 Output 2 (Relay or Logic)
This is optional and is output only. It may be relay or logic output as output 1.
3.6 AA Output Relay
Changeover relay (Form C) rated 2A 264Vac resistive
* 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 15nF 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.

10 ENG 3116 User Guide Part No. HA028005ENG Issue 2.0 May 04
3.7 Power Supply
1. Before connecting the instrument to the power line, make sure that the line voltage corresponds to the description
on the identification label
2. For 24V the polarity is not important
3. The power supply input is not fuse protected. This should be provided externally:
Instrument fuse ratings are as follows:-
• For 24 V ac/dc fuse type T rated 2A 250V
• For 85/265Vac fuse type T rated 2A 250V

4. Installation Safety Requirements
Safety Symbols
Various symbols may be used on the controller. They have the following meaning:
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 with the temperature sensor 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.
!
Caution, (refer to
accompanying documents)
Equipment protected throughout
by DOUBLE INSULATION

12 ENG 3116 User Guide Part No. HA028005ENG Issue 2.0 May 04
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.
Over-temperature protection
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.

3116 User Guide Part No. HA028005ENG Issue 2.0 May 04 ENG 13
5. 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 5.1)
2. The instrument has been supplied configured in accordance with the Quick Start code (go to section 5.3)
5.1 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 *characters will change to ‘-‘. The first one flashing. xindicates the option is not fitted
2. Press
▲or ▼to change the character currently flashing to the required code shown in the quick code table.
1. Press
!to scroll to the next character. If you need to return to the first character press !. When all five
characters have been configured the display will go to Set 2 (3216 only).
When the last digit has been entered press !again, the display will show
No
ExiT Press ▲or ▼to YES.
The controller will automatically go to the operator level.

5.2 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, hold
down the !button, then power up the controller. You must keep the button pressed until ‘code’ appears. 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. You can then re-configure the controller through
the Quick Codes.
Note:- If the quick codes re-appear with decimal points between each character this means THE QUICK CODES
MAY NO LONGER BE VALID. This is because a parameter (not necessarily a Quick Code parameter) which is available in
the controller at a deeper level of access* has been altered. You can, however, re-adjust the Quick Codes again at this
point to re-configure the controller, (or proceed to
Yes
ExiT state).
* The procedure for a full configuration is described in the 3116/3216 Engineering Handbook Part No. HA027986 which
may be downloaded from www.eurotherm.co.uk.

If the alarm is still present the ALM beacon lights continuously.
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
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.
5.4.3

3116 User Guide Part No. HA028005ENG Issue 2.0 May 04 ENG 19
5.4.4 Auto/Manual/Off Mode
Auto mode is the normal closed loop operation where the output is adjusted automatically by the controller in response
to a change in the input signal.
Manual mode means that the controller output power can be adjusted directly by the user. The input sensor is still
connected and reading the PV but the control loop is open. The current level of the power output is adopted at the
point of switch over from Auto to Manual. This is referred to as ‘Bumpless Transfer’. The power output can be increased
or decreased using the ▼or ▲buttons. Similarly, when Manual to Auto is selected the current manual output
power is taken and the controller will then take over control. If the controller is powered down it will resume the same
mode when powered up again.
Off mode can be selected or when using a timer configured to turn the power output off at the end of a timed period.
!Manual operation must be used with care and the power level set must be chosen such that no damage can occur
to the process. The use of a separate ‘over-temperature’ controller is recommended.
