Standard Connections
These are connections which are common to all instruments in the range.
PV Input (Measuring Input)
1. Run input wires separate from power cables
2. When shielded cable is used, it should be grounded at one point only
3. 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
4. This input is not isolated from logic I/O A and logic I/O B
Thermocouple or Pyrometer Input
•Use the correct type of thermocouple compensating cable, preferably
shielded, to extend wiring
•It is not recommended to connect two or more instruments to one
thermocouple
•The resistance of the three wires must be the same
•The line resistance may cause errors if it is greater than 22Ω
Note 1: The RTD wiring is not the same as 2400 series instruments. It is the
same as 26/2700 series
Note 2: For 2-wire this is a local link

Digital I/O
These terminals may be configured as logic inputs, contact inputs or logic outputs in any combination.
It is possible to have one input and one output on either channel.
!The Digital IO is not isolated from the PV input. The controller is designed to
operate normally if the input sensor is connected to 240Vac, but in this case these terminals will
be at this potential.

The fixed digital logic outputs may be used to power remote 2 wire transmitters. The fixed digital
I/O are, however, not isolated from the PV input circuit, so this does not allow the use of 3 or 4 wire
transmitters. An isolated module must be used for the 3 and 4 wire types.

Snubbers
Snubbers are used to prolong the life of relay contacts and to reduce interference when switching
inductive devices such as contactors or solenoid valves. The fixed relay (terminals AA/AB/AC) is
not fitted internally with a snubber and it is recommended that a snubber be fitted externally. If
the relay is used to switch a device with a high impedance input, no snubber is necessary.
All relay modules are fitted internally with a snubber since these are generally required to switch
inductive devices. However, snubbers pass 0.6mA at 110V and 1.2mA at 230Vac, which may be
sufficient to hold on high impedance loads. If this type of device is used it will be necessary to
remove the snubber from the circuit.
The snubber is removed from the relay module as follows:-
1. Unplug the controller from its sleeve
2. Remove the relay module
3. Use a screwdriver or similar tool to snap out the track.
The view shows the tracks in a Dual Relay Output module.

3504 (1) Polarising keys are intended to prevent modules,
not supported by this controller, from being fitted.
Supported modules are defined by the order code -
the
arrow on the polarising key points in the upward
direction when these are fitted. An example of an
unsupported module is
an unisolated module (coloured
red) from a 2400 series controller. It is possible to fit
such a module but it is the users responsibility to
ensure that it is safe to install it in the particular
application. When this has been verified the polarising
key may be adjusted with a screwdriver to point in the
down direction.

If the Controller is new and has not previously
been configured it will start up showing the ‘Quick
Start’ codes. This is a built in tool which enables
you to configure the input type and range, the
output functions and alarms.
!Incorrect configuration can result in
damage to the process and/or personal injury
and must be carried out by a competent person
authorised to do so. It is the responsibility of
the person commissioning the instrument to
ensure the configuration is correct.
To Configure Parameters in Quick
Start Mode
With ‘QckStart’ selected, press to scroll
through a list of parameters.
Edit the parameters using Vor .
When the required choice is selected a brief blink
of the display indicates that it has been accepted .
The first parameter is ‘Units’.
This parameter is associated
with Loop 1 ‘LP1’ and resides
in the ‘PV Input’ list as shown.
Continue setting up the paras presented until the
‘Finished’ view is displayed.
If all parameters are set up as required press V
or to select ‘Yes’.
The loop(s) are set to Auto on exit from Quick
Start and the controller re-starts in operator level
2.
The ‘HOME’ display is shown - see ‘Normal
Operation’.

Note 1) Parameters only appear if the function has been turned on, eg If ‘Control Channel 1’ = ‘Off’, ‘Chan 1’ does not appear in this list. When a control
channel is configured for valve positioning, LgcIO LA and LgcIO LB act as a complementary pair. If, for example, Chan 1 is connected to LgcIO LA
(valve raise) then LgcIO LB is automatically set to Chan 1 (valve lower). This ensures the valve is never raised and lowered simultaneously.
The same complementary behaviour also applies to dual output modules and channels A and C of triple output modules
Note 2) If any input function, for example Chan 1, is connected to another input it will not appear in this list
Note 3) Is available if the Control Channel is not On/Off and is allocated to the LA, LB or AA output as applicable
Note 4) For valve position control Chan 1 or Chan 2 will not appear in this list. Valve position outputs can only be dual outputs such as LA and LB or dual
relay/triac output modules
To Re-enter Quick Start Mode
If you have exited from Quick Start mode (by selecting ‘Yes’ to the ‘Finished’ parameter) and you need to make further changes, the Quick start mode can be entered again at any time.
1. Hold down then power up the controller. Keep this button pressed until the ‘Startup’ - ‘Goto QckStart’ screen is displayed.
2. Press to enter the quick start list. You will then be asked to enter a passcode.
3. Use Vor Wto enter the passcode – default 4. If an incorrect code is entered the display reverts to the ‘Quick Start’ view.
It is then possible to repeat the quick configuration as described previously.
Note: The Quick Start view contains two additional parameters - ‘Cancel’ and ‘Config’.
Select Cancel to revert to normal operating mode.
Config will allow full configuration mode to be entered (after entering the correct pass code). Configuration is described in the Engineering Manual HA027988.

•The inputs and outputs to and from the IO
Expander are isolated 240Vac.
Digital Communications modules can be fitted in both H and J positions. The connections being available on HA to HF and JA to JF depending on the position in which the module is fitted. The two positions could
be used, for example, to communicate with ‘iTools’ configuration package on one position, and to a PC running a supervisory package on the second position.
Communications protocols may be Modbus, EIBisynch, DeviceNet®, Profibus or Modbus TCP.
Note:- In order to reduce the effects of RF interference the transmission line should be grounded at both ends of the screened cable. However, if such a course is taken care must be taken to ensure that
differences in the earth potentials do not allow circulating currents to flow, as these can induce common mode signals in the data lines. Where doubt exists it is recommended that the Screen (shield) be grounded
at only one section of the network as shown in all of the following diagrams.
A further description of Modbus and EIBisynch communications is given in 2000 series Communications Handbook, Part No. HA026230, which can be downloaded from www.eurotherm.co.uk.

30oC to +75oC.
Electrostatic discharge precautions. Always observe all electrostatic precautions before handling the unit.
Service and repair. This instrument has no user serviceable parts. Contact your supplier for repair.
Cleaning. Isopropyl alcohol may be used to clean labels. Do not use water or water based products. A mild soap solution may be used to clean other exterior surfaces.
Electromagnetic compatibility. This instrument conforms with the essential protection requirements of the EMC Directive 89/336/EEC, by the application of a Technical Construction File. It satisfies the general
requirements of the industrial environment defined in EN 61326.
Caution: Charged capacitors. Before removing an instrument from its sleeve, disconnect the supply and wait at least two minutes to allow capacitors to discharge. Avoid touching the exposed electronics of an
instrument when withdrawing it from the sleeve.
Safety Symbols. Symbols used on the instrument have the following meaning:
!
Caution, refer to accompanying documents) Protective Conductor Terminal
Installation Category and Pollution Degree. This unit has been designed to conform to BSEN61010 installation category II and pollution degree 2, 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. However, a temporary conductivity caused by condensation must be expected.
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 installed 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 for use in 240Vac CATII.
Wiring. It is important to connect the unit in accordance with the data in this sheet ensuring that the protective earth connection is ALWAYS fitted first and disconnected last. Wiring must comply with all local
wiring regulations, i.e. UK, the latest IEE wiring regulations, (BS7671), and USA, NEC Class 1 wiring methods.
!
Do not connect AC supply to low voltage sensor input or low level inputs and outputs.
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.
Conductive pollution. Electrically conductive pollution i.e. carbon dust, MUST be excluded from the enclosure in which the controller is installed. To secure a suitable atmosphere in conditions of conductive
pollution, fit an air filter to the air intake of the enclosure. Where condensation is likely, include a thermostatically controlled heater in the enclosure.
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.
To prevent overheating of the process under fault conditions, a separate over-temperature protection unit should be fitted which will isolate the heating circuit. This must have an independent temperature
sensor.
Note: Alarm relays within the unit will not give protection under all failure conditions.
Installation Requirements for EMC. To comply with European EMC directive certain installation precautions are necessary:-
•General guidance. Refer to EMC Installation Guide, Part no. HA025464.
•Relay outputs. It may be necessary to fit a suitable filter to suppress conducted emissions. Filter requirements depend on the type of load. Typical applications may use Schaffner FN321 or FN612.
•Table top installation. If using a standard power socket, compliance with commercial and light industrial emissions standard is usually required. To comply with conducted emissions standard, a suitable mains
filter must be installed, such as Schaffner FN321 or FN612.
