* Polarising Keys.

Polarising keys are intended to prevent modules which are not supported in this controller from being fitted into the controller. An example might be an unisolated module (coloured red) from a 2400 controller series. When pointing towards the top, as shown, the key prevents a controller, fitted with an unsupported module, from being plugged into a sleeve which has been previously wired for isolated modules. If an unisolated module is to be fitted, it is the users responsibility to ensure that it is safe to install the controller in the particular application. When this has been verified the polarising key may be adjusted with a screwdriver to point in the down direction.

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).

1.5.4.1 General Note About Inductive Loads

High voltage transients may occur when switching inductive loads such as some contactors or solenoid valves.

For this type of load it is recommended that a ‘snubber’ is connected across the contact of the relay switching the load. The snubber typically consists of a 15nF capacitor connected in series with a 100

Ω

resistor and will also prolong the life of the relay contacts.

!

When the relay contact is open and it is connected to a load, the snubber passes a current (typically 0.6mA at 110Vac and 1.2mA at 240Vac. It is the responsibility of the installer to ensure that this current does not hold on the power to an electrical load. If the load is of this type the snubber should not be connected.

See also section 1.7.9.

3. Use copper conductors only

4. For 24V the polarity is not important

5. It is the Users responsibility to provide an external fuse or circuit breaker.

For 24 V ac/dc fuse type T rated 4A 250V

For 85/265Vac fuse type T rated 1A 250V

Safety requirements for permanently connected equipment state:

• a switch or circuit breaker shall be included in the building installation

• it shall be in close proximity to the equipment and within easy reach of the operator

• it shall be marked as the disconnecting device for the equipment

Note: a single switch or circuit breaker can supply more than one instrument

1.6 Plug in I/O Module Connections

Plug in I/O modules can be fitted in three positions in the 3508 and six positions in 3504. The positions are marked

Module 1, 2, 3, 4, 5, 6. With the exception of the Analogue Input module, any other module listed in this section, can be fitted in any of these positions. To find out which modules are fitted check the ordering code printed on a label on the side of the instrument. If modules have been added, removed or changed it is recommended that this is recorded on the instrument code label.

The function of the connections varies depending on the type of module fitted in each position and this is shown below. All modules are isolated.

1.7 Digital Communications Connections

Digital Communications modules can be fitted in two positions in both 3508 and 3504 controllers. 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 Ethernet.

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.

1.7.10 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, as shown in the example wiring diagram. 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 below shows the tracks in a Dual Relay Output module.

Break out tracks as required to disconnect the snubber



2. Chapter 2: Getting Started

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. Power up out of the box – when the controller has no preset configuration and is switched on for the very first time it will start up in 'QuickStart mode. This is an intuitive tool for configuring the controller and is described in section 2.1 below.

2. The controller has been powered up previously and is already configured. In this case go to section 2.3.

2.1 Quick Start - New Controller (Unconfigured)

When the controller is switched on for the very first time it will display the 'Startup' screen shown below.

* Manual mode is always selected when in Quick Start mode because the controller resets to cold start when Quick Start is selected.

[Note 3]

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) 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

Modules

The following parameters configure the plug in I/O modules. I/O Modules can be fitted in any available slot in the instrument (6 slots in 3504,

3 slots in 3508). The controller automatically displays parameters applicable to the module fitted - if no module is fitted in a slot then it does not appear in the list.

Each module can have up to three inputs or outputs. These are shown as A, B or C after the module number and this corresponds to the terminal numbers on the back of the instrument. If the I/O is single only A appears. If it is dual A and C appears if it is triple A, B and C appear.

2.2 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. The action which takes place depends on one of two previous conditions as follows:-

2.2.1 Power up After a Quick Start Configuration

1. Hold down then power up the controller. Keep this button pressed until the Quick start screen as shown in section 2.1 is displayed.

to enter the quick start list. You will then be asked to enter a passcode.

3. Use or

▼ to enter the passcode – default 4 – the same as the configuration level passcode. If an incorrect code is entered the display reverts to the ‘Quick Start’ view section 2.1.

It is then possible to repeat the quick configuration as described previously.

The Quick Start view shown in section 2.1 now contains an additional parameter - ‘Cancel’. This is now always available after a power up, and, if selected, will take you into normal operating mode, section 2.3.

2.2.2 Power up After A Full Configuration

Repeat 1,2 and 3 above.

Full configuration allows a greater number of parameters to be configured in a deeper level of access. This is described in the Engineering Handbook Part No. HA027988.

If the controller has been re-configured in this level, a ‘WARNING’ message, ‘Delete config?’ - ‘No’ or ‘Yes’, will be displayed. If ‘No’ is selected the display drops back to the ‘GoTo’ screen. or

▼ to select ‘Yes’ to confirm or ! the WARNING message). to cancel. (If no button is pressed for about 10 seconds the display returns to



If ‘Yes’ is selected the Quick start defaults will be re-instated. It is then necessary to reset all the Quick start parameters.

Switch on the controller. Following a brief self-test sequence, the controller will start up in AUTO mode and Operator

Level 1. This section describes the operation of the controller in this level.

AUTO is the normal closed loop temperature control mode which means that the output power is adjusted automatically by the controller in response to the measurement from the input sensor. In this mode the format of the display for a new instrument is shown below. It is called the HOME display.

Non Latched Alarms

If the alarm condition is present when the alarm is acknowledged, the alarm beacon will be continuously lit. This state will continue for as long as the alarm condition remains. When the alarm condition disappears the indication will also disappear.

If a relay has been attached to the alarm output, it will de-energise when the alarm condition occurs and remain in this condition until the alarm is acknowledged AND it is no longer present.

If the alarm condition disappears before it is acknowledged the alarm indication disappears as soon as the condition disappears.

Automatic Latched Alarms

The alarm continues to be active until both the alarm condition is removed AND the alarm is acknowledged. The acknowledgement can occur BEFORE the condition causing the alarm is removed.

Manual Latched Alarms

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.



The lower section of the HOME display contains an alpha-numeric set of messages. These messages change between different controller types and operating modes and are grouped in summary pages.

2.9 Introduction to Configuration using iTools

iTools is a PC based configuration package which is used to configure instruments. The controller may be connected to the PC in three ways:-

1. Using an infra red clip (IR) attached to the front fascia. Set the parameter ‘IR Mode’ in the ‘Access’ list to ‘On’.

2. Using a configuration clip which plugs into the side of the controller

Both items are available from your supplier

3. Using a RS232, RS485 or RS422 digital communications interface connected to the H or J terminals

iTools provides:-

• Parameter Set up

•

2.14.1 Function Block

A Function Block is an algorithm which may be wired to and from other function blocks to make a control strategy.

The Graphical Wiring Editor groups the instrument parameters into function blocks. Examples are: a control loop and a mathematical calculation.

Each function block has inputs and outputs. Any parameter may be wired from, but only parameters that are alterable may we wired to.

A function block includes any parameters that are needed to configure or operate the algorithm.

2.14.2 Wire

A wire transfers a value from one parameter to another. They are executed by the instrument once per control cycle.

Wires are made from an output of a function block to an input of a function block. It is possible to create a wiring loop, in this case there will be a single execution cycle delay at some point in the loop. This point is shown on by a || symbol and it is possible to choose where that delay will occur.

Dotted lines around a function block show that it requires downloading.

2.14.3 Using Function Blocks

If a function block is not faded in the tree then it can be dragged onto the diagram.

The block can be dragged around the diagram using the mouse.

A labelled loop block is shown here. The label at the top is the name of the block.

When the block type information is alterable click on the box with the arrow in it on the right to edit that value.

The inputs and outputs which are considered to be of most use are always shown.

In most cases all of these will need to be wired up for the block to perform a useful task. There are exceptions to this and the loop is one of those exceptions.

If you wish to wire from a parameter which is not shown as a recommended output click on the icon in the bottom right and a full list of parameters in the block will be shown, click on one of these to start a wire.

To start a wire from a recommended output just click on it.

3. Chapter 3 Safety and EMC Information

This controller is manufactured in the UK by Eurotherm Ltd.

Please read this section carefully before installing the controller

This controller is intended for industrial temperature and process control applications when it will meet the requirements of the European Directives on Safety and EMC. Use in other applications, or failure to observe the installation instructions of this handbook may impair safety or EMC. The installer must ensure the safety and EMC of any particular installation.

3.1 GENERAL

The information contained in this manual is subject to change without notice. While every effort has been made to ensure the accuracy of the information, your supplier shall not be held liable for errors contained herein.

3.1.1 Safety

This controller complies with the European Low Voltage Directive 73/23/EEC, by the application of the safety standard

EN 61010.

This controller conforms with the essential protection requirements of the EMC Directive 89/336/EEC, by the application of appropriate product specific international standards . This instrument satisfies the general requirements of the industrial environment defined in EN 61326. For more information on product compliance refer to the

Technical Construction File.

3.1.3 Unpacking and storage

The packaging should contain an instrument mounted in its sleeve, two mounting brackets for panel installation and an

Installation & Operating guide. Certain ranges are supplied with an input adapter.

If on receipt, the packaging or the instrument are damaged, do not install the product but contact your supplier. If the instrument is to be stored before use, protect from humidity and dust in an ambient temperature range of -10 o

C to +70 o

C.

3.2 Service and repair

This controller has no user serviceable parts. Contact your supplier for repair.

3.2.1 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.

3.2.2 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.

3.2.3 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.



3.3 Installation Safety Requirements

Various symbols are used on the instrument, they have the following meaning:

!

3.3.2 Personnel

Installation must only be carried out by suitably qualified personnel.

3.3.3 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.

3.3.4 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.

The logic IO is not isolated from the PV inputs.

3.3.5 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.

The installation must include a power isolating switch or circuit breaker. The device should be mounted in close proximity to the controller, within easy reach of the operator and marked as the disconnecting device for the instrument.

The power supply to the system should be fused appropriately to protect the cabling to the units.

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.

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, install 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:-



3.3.10 Installation Category II

The rated impulse voltage for equipment on nominal 230V supply is 2500V.

3.3.10.1 Pollution Degree 2

Normally only non conductive pollution occurs. Occasionally, however, a temporary conductivity caused by condensation shall be expected.

3.3.11 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.

3.3.12 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;

• 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.

3.4 Installation Requirements for EMC

To ensure compliance with the European EMC directive certain installation precautions are necessary as follows:

•

For general guidance refer to EMC Installation Guide, HA025464.

• When using relay outputs it may be necessary to fit a filter suitable for suppressing the conducted 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.

3.4.1 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.
