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 2.49Ω across the + and - input as shown

* 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.

4. Installation Safety Requirements
Safety Symbols
Various symbols may be used on the controller. They have the following meaning:
!
Caution, (refer to
accompanying documents)
Equipment protected throughout
by DOUBLE INSULATION
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.
3116 User Guide Part No. HA028005ENG Issue 2.0 May 04
ENG
11
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.

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 ‘c o d e ’ 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
E xiT
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.

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
buttons. Similarly, when Manual to Auto is selected the current manual output
or decreased using the
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.

A timer can be configured to operate in four different modes. These can be selected in Level 2 using the ‘TM.CFG’
parameter as:•
Dwell Timer
•
Delayed switch on timer
•
Soft start timer
There are four operating states:
1.
Run. This starts the timer
2.
Hold. This stops the timer at the elapsed time. It will start again from the elapsed time when Run is selected again.
3.
Reset. This sets the timer back to zero. It can be run again from this state.
4.
End cannot be set - it occurs automatically when the timer has counted down to zero

Dwell Timer
A dwell timer (TI.CFG = DWELL) is used to control a process at a fixed temperature for a defined period. The action
which occurs at the end of the timed period depends on the configuration of the END.T parameter.

If THRES = 2o (for example) timer will show TIMER RUNNING with the RUN beacon on but will not start counting
down until the temperature is, first, within 2o of SP. Then the threshold is ignored.
2.
The DWELL period can be reduced or increased when the timer is running. If it is reduced to meet the Time
Elapsed the timer will change to the End state.
3.
A-M can only be selected when in reset

Soft Start Timer
The timer is used to start a process at reduced power and/or reduced setpoint. Timing starts at power up or when ‘Run’
is selected.
When the Timer Status = Run, the controller power is limited by the soft start power limit parameter. The Soft Start
setpoint is a threshold which, when exceeded, sets the timer to end. If the temperature is already above this threshold
when the timer is set to run, the timer will time out immediately.
When the timer status = reset, the controller is controlling at SP1
