Installation and Basic Operation
1. What Instrument Do I Have?
Thank you for choosing the 3116 Temperature Controller.
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
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 where the last two
sets of five digits show the Quick Code. If the Quick Code shows XXXXX the controller will need to be configured when it
is first switched on.
1.1 Unpacking Your Controller
The following items are included in the box:-
• Controller mounted in its sleeve
• Two panel retaining clips mounted on the sleeve
• IP65 sealing gasket mounted on the sleeve
• Component packet containing a snubber for each relay output (see section 3.6) and a 2.49Ωresistor for current
inputs (see section 3)
• This User Guide

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
latching ears outwards and pulling it forward out of the sleeve.
When plugging it back into its sleeve, ensure that the latching ears click back into place to maintain the IP65 sealing.

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.
