1.4 Step 1: Installation

This indicator is intended for permanent installation, for indoor use only, and enclosed in an electrical panel

Select a location which is subject to minimum vibrations, the ambient temperature is within 0 and

55 o

C (32 - 131 o

F) and humidity 5 to 95% RH non condensing.

The indicator can be mounted on a panel up to

15mm thick

To ensure IP65 and NEMA 4 front sealing against dust and water, mount on a non-textured surface.

Please read the safety information in section 3 before proceeding. The EMC Booklet part number

HA025464 gives further installation information.

1.4.1 Panel Mounting the Indicator

1. Prepare a cut-out in the mounting panel to the size shown. If a number of instruments are to be mounted in the same panel observe the minimum spacing shown.

2. Fit the IP65 sealing gasket behind the front bezel of the indicator

3. Insert the indicator through the cut-out

4. Spring the panel retaining clips into place.

Secure the indicator in position by holding it level and pushing both retaining clips forward.

5. Peel off the protective cover from the display

* General Notes 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 series connected resistor/capacitor (typically 15nF/100 Ω). A snubber will also prolong the life of the relay contacts.

A snubber should also be connected across the output terminal of a triac output to prevent false triggering under line transient conditions.

WARNING

When the relay contact is open, or it is connected to a high impedance load, it passes a current (typically

0.6mA at 110Vac and 1.2mA at 230Vac). 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.

Voltage Directive 2006/95/EC, by the application of the safety standard EN 61010.

Electromagnetic compatibility

This indicator conforms with the essential protection requirements of the EMC Directive 2004/108/EC by the application of a Technical Construction File. 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.

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.

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 is 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.

Service and repair

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

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.

Electrostatic discharge precautions

When the indicator is removed from its sleeve, some of the exposed electronic components are vulnerable to damage by electrostatic discharge from someone handling the indicator. To avoid this, before handling the unplugged indicator discharge yourself to ground.

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.

3.1 Installation Safety Requirements

Safety Symbols

Various symbols may be used on the indicator. They have the following meaning:

!

Caution, (refer to accompanying documents)

Equipment protected throughout by DOUBLE

INSULATION

☺

Helpful hints

Personnel

Installation must only be carried out by suitably qualified personnel in accordance with the instructions in this handbook.

Enclosure of Live Parts

To prevent hands or metal tools touching parts that may be electrically live, the indicator must be enclosed in an enclosure.

Caution: Live sensors

The indicator 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

230Vac +15% CATII.

Wiring

It is important to connect the indicator 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 indicator, within easy reach of the operator and marked as the disconnecting device for the instrument.

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

230Vac:

• relay output to logic, dc or sensor connections;

• any connection to ground.

The indicator 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 must be excluded from the cabinet in which the indicator 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.

This product has been designed to conform to

BSEN61010 installation category II, pollution degree 2.

These are defined as follows:-

Installation Category II (CAT II)

For equipment on nominal 230V supply, the maximum rated impulse voltage is 2500V.

Pollution Degree 2

Normally only non conductive pollution occurs.

Occasionally, however, a temporary conductivity caused by condensation shall be expected.

Grounding of the temperature sensor shield

In some installations it is common practice to replace the temperature sensor while the indicator 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

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,

3200iSeries Indicators with an independent temperature sensor, which will isolate the heating circuit.

This indicator can be used in addition to a controller as an over temperature device. It is recommended that the relay used to indicate the alarm condition should be set to high alarm configured with sensor break and inverse ‘ Inv’ operation so that it relaxes to the alarm condition when power is removed.

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.

• 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.

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.



4. Switch On

4.1 New Indicator

5.3 Strain Gauge Calibration

The 32h8i/SG indicator is designed to operate with symmetrical bridge type strain gauges, nominally

350 Ω in each arm. It is generally necessary to calibrate the instrument to the transducer in use. This can be done in Operator Level 2 or 3 using any one of three methods. These are:-

CELL. Here a load cell is connected directly to the input terminals marked Signal + and – (section 5.3.1).

COMPARISON. The load cell is connected as above but the calibration is compared with a reference device or reference weight (section 5.3.2).

SHUNT. This is so called since it refers to switching a calibration resistor across one arm of a four wire measurement bridge in a strain gauge transducer

(section 5.3.3).

To configure the different modes:-

The high (span) and low (zero) adjustment of the transducer can be performed automatically or manually.

Manual allows the low point and high point to be calibrated individually.

Automatic performs both low and high point calibration by the selection of one parameter.

5.3.4 Manual Calibration

1. Remove all pressure from the transducer to establish a zero reference

2. In operator level 2, press

 shown in the lower display.

80% of the transducer span

4. Press



to scroll to LO.CAL and press

V or

W

to select yes

5. The indicator will show busy as it calibrates the minimum weight condition. pass or faiL will be indicated when the low point calibration is complete.

6. Press



to scroll to HI.CAL and repeat the above steps to calibrate 80% (as set in 3 above) of the transducer span

The high calibration value may be checked by shorting Cal 1 and Cal 2. For example a 0 – 3000psi probe will read 2400 when Cal 1 and Cal 2 are linked.

5.3.5 Automatic Calibration

1. Remove all pressure from the transducer to establish a zero reference

2. In operator level 2, press

 shown in the lower display

until AUT.SG is

3. Press

V or

W

to select yes

The indicator will automatically perform the following sequence:- a. Disconnect the calibration resistor R

CAL b. Calculate the low point calibration value by continuously averaging two sets of 50 measurements of the input until stable readings are obtained.

Lo will be indicated during this process. c. Connect the calibration resistor by closing a contact between terminals VI and LA

Calculate the high point calibration value by continuously averaging two sets of 50 measurements of the input until stable readings are obtained. Hi will be indicated during this process.

5.3.6 Calibration Using a Digital Input

A digital input may have been set by selecting Z in the quick codes (section 4.1) to allow the transducer to be calibrated automatically via an external source such as a switch or pushbutton. In this case pressing the button will have the same effect as selecting yes in 3 above.

5.3.6.1 Fail

Fail will be displayed in any of the above calibration procedures if the calibration is not possible. For example, the input shows Sensor Break or is out of range or the transducer or load cell is not connected correctly. It is necessary to correct the fault and start the procedure again.


5.4 Recipes

It is possible to store operating values in up to five different recipes by taking a snapshot of the current settings and storing these in a recipe number.

Examples, of typical operating parameters may be alarm setpoint values. A particular recipe number may then be recalled for a particular process.

5.4.1 To Store Values in a Recipe

1. In the list of parameters, press

 store

to select

2. Select a recipe number from 1 to 5 in which to store the current settings. The indicator will show done when the values are stored. All previous values which may have been stored in this recipe are overwritten.

5.4.2 To Load a Recipe

1. In the list of parameters, press

 rec. no

to select

Select a recipe number from 1 to 5 in which the required settings have been stored. The values will automatically loaded from the recipe. If no values have been stored in that recipe, faiL will be indicated


5.5 FM and Alarm Units

3200 indicators supplied to Function code FM are FM approved.

3200 indicators supplied to Function code DN are approved to EN14597.

The instrument label is marked accordingly.

In these instruments the alarm operating the AA relay output is set to inverted and latching. This function cannot be altered.

When the instrument is configured using the Quick

Start codes (section 4.1), Alarm 1 is used to operate both Outputs 1 and 4 (AA relay). The Quick Start configuration for the AA relay will enable and configure Alarm 4 but Alarm 4 will not be used to operate Output 4.

!

If Quick Start is used to configure Alarm 1 as a high alarm and Alarm 4 as a low alarm, then the resulting configuration will be that the high alarm 1 is used to drive both outputs 1 and 4. The low alarm 4 will not be connected to any output.

Further details on latching and blocking alarms can be found in section 10.1.



6. Access to Further Parameters

Parameters are available under different levels of security and are defined as Level 1 (Lev1), Level 2

(Lev2), Level 3 (Lev 3) and Configuration (C on f).

Level 1 has no passcode since it contains a minimal set of parameters generally sufficient to run the process on a daily basis. Level 2 allows access to parameters which may used in commissioning an indicator or settings between different products or batches. This has been described in the previous section.

Level 3 and Configuration level parameters are also available as follows:-

6.1 Level 3

Level 3 makes all operating parameters available and alterable (if not read only). It is typically used when commissioning an indicator

Examples are:-

Range limits, setting alarm levels, communications address.

6.2 Configuration Level

This level makes available all parameters including the operation parameters so that there is no need to switch between configuration and operation levels during commissioning. It is designed for those who may wish to change the fundamental characteristics of the instrument to match the process.

Examples are:-

Input (thermocouple type); Alarm type;

Communications type.

WARNING

Configuration level gives access to a wide range of parameters which match the indicator to the process. Incorrect configuration could result in damage to the process and/or personal injury. It is the responsibility of the person commissioning the process to ensure that the configuration is correct.

In configuration level the indicator is not providing alarm indication. Do not select configuration level on a live process.

7. Process Input

Parameters in the input list configure the input to match your sensor. These parameters provide the following features:-

Input Type and linearisation

Display units and resolution

Input filter

Fault detection

User calibration

Over/Under range

Thermocouple (TC) and 3-wire resistance thermometer (RTD) temperature detectors

Linear input (-10 to +80mV) through external shunt or voltage divider, mA assumes a

2.49

Ω external shunt.

See the table in section 7.1.1. for the list of input types available

The change of display units and resolution will all the parameters related to the process variable

First order filter to provide damping of the input signal. This may be necessary to prevent the effects of excessive process noise on the PV input from causing poor control and indication. More typically used with linear process inputs.

Sensor break is indicated by an alarm message ‘Sbr’. For thermocouple it detects when the impedance is greater than pre-defined levels; for RTD when the resistance is less than 12 Ω.

Either by simple offset or by slope and gain. See section 13.2. for further details.

When the input signal exceeds the input span by more than 5% the PV will flash indicating under or over range. If the value is too high to fit the the number of characters on the display ‘HHHH’ or ‘LLLL’ will flash. The same indications apply when the display is not able to show the PV, for example, when the input is greater than

7.1.3 PV Offset

All ranges of the indicator have been calibrated against traceable reference standards. This means that if the input type is changed it is not necessary to calibrate the indicator. There may be occasions, however, when you wish to apply an offset to the standard calibration to take account of known errors within the process, for example, a known sensor error or a known error due to the positioning of the sensor.

In these instances it is not advisable to change the reference (factory) calibration, but to apply a user defined offset.

PV Offset applies a single offset to the temperature or process value over the full display range of the indicator and can be adjusted in Level 3. It has the effect of moving the curve up a down about a central point as shown in the example below:-

7.1.3.1 Example: To Apply an Offset:-

Connect the input of the indicator to the source device which you wish to calibrate to

Set the source to the desired calibration value

The indicator will display the current measurement of the value

If the display is correct, the indicator is correctly calibrated and no further action is necessary. If you wish to offset the reading:-

It is also possible to apply a five point offset which adjusts both low and high points. This is done in Level

7.1.4 PV Input Scaling

Input scaling applies to the linear mV and volts input ranges only. This is set by configuring the INPUT TYPE parameter to mV or VoLt, mV has an input range of –

10 to 80mV. Using an external burden resistor of

2.49

Ω, the indicator can be made to accept 4-20mA from a current source. Scaling of the input will match the displayed reading to the electrical input levels from the transducer. PV input scaling can only be adjusted in Configuration level and is not provided for direct thermocouple or RTD inputs.

The graph below shows an example of input scaling, where it is required to display 2.0 when the input is

4mV and 500.0 when the input is 20mV .

If the input exceeds +5% of the inp.Lo or inp.Hi settings, sensor break will be displayed.

8. Input/Output Channels

Indicators may be ordered with relay, analogue or logic channels to provide different interfaces to plant devices.

The connections for these channels is made on terminals 1 to 3.

8.1 Output Channel 1 (OP-1) - 32h8i and 3204i Indicators

Output 1 is always a changeover relay in 32h8i and 3204i indicators and connected to terminals 1A, 1B and 2A. It is typically used to provide external indication of alarms. OP1 beacon is operated from this output.

Output 1 is configured using the parameters in the following table:-

10. Alarms

Alarms are used to alert an operator when a pre-set level has been exceeded. They are indicated by a scrolling message on the display and the red ALM beacon. They may also switch an output – usually a relay (see section

8.3.2) to allow external devices to be operated when an alarm occurs.

10.1 Types of Alarm

Up to six different alarms are available:-

1. Alarm 1

2. Alarm 2

3. Alarm 3

4. Alarm 4

Configurable as any of:-

Rising Rate of Change r.roc - the alarm is triggered if the rate of increase in PV exceeds the set level

Falling Rate of Change F.roc. - the alarm is triggered if the rate of decrease in PV exceeds the set level

The alarm is triggered if the sensor is open circuit 5. Sensor

Fault Alarm

6. Power Fail An alarm is indicated after a power cycle. It is acknowledged and cancelled using ‘Ack’ buttons.

This may be useful to indicate that a power failure has occurred and the peak values will only apply since return of the power.

Hysteresis

Latching Alarm is used to hold the alarm condition once an alarm has been detected. It may be configured as:- none Non latching A non latching alarm will reset itself when the alarm condition is removed

Auto Automatic An auto latching alarm requires acknowledgement before it is reset. The acknowledgement can occur BEFORE the condition causing the alarm is removed.

Man Manual 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.

Evt Event ALM beacon does not light but an output associated with this parameter will activate. A scrolling message may be configured using iTools, as described in section 14.5.3. If a message has been configured it will scroll across the display while the event is true. An ‘Event’ is not acknowledged.

Blocking

Alarms

Rising rate of change

(units/minute) is the difference between the point at which the alarm switches ‘ON’ and the point at which it switches ‘OFF’. It is used to provide a definite indication of the alarm condition and to prevent alarm relay chatter.

The alarm may be masked during start up of a process. Blocking prevents the alarm from being activated until the process has first achieved a safe state. It is used to ignore start up conditions which are not representative of running conditions.

A blocking alarm is re-initiated after a setpoint change.

See section 10.1 for an explanation of the behaviour of blocking alarms under different conditions.

10.1.1 Alarm Relay Output

Alarms can operate relay outputs 1, 2 or 4. Any individual alarm can operate an individual output or any combination of alarms, up to four, can operate an individual output. They are either supplied preconfigured in accordance with the ordering code or set up in the Quick Codes or in configuration level .

Section 8.3.2. describes how to configure the alarm outputs using the ‘SOURCE’ parameters.

10.1.2 Alarm Indication

•

ALM beacon flashing red = a new alarm

(unacknowledged)

•

This is accompanied by a scrolling alarm message. A typical default message will show the source of the alarm followed by the type of alarm. For example, ‘ALARM 1 HIGH’

•

Using Eurotherm iTools configuration package, it is also possible to download customised alarm messages. An example might be, ‘PROCESS

TOO HOT’.

•

If more than one alarm is present further messages are flashed in turn in the main display.

The alarm indication will continue while the alarm condition is present and is not acknowledged.

•

ALM beacon on continuously = alarm has been acknowledged.

10.1.3 To Acknowledge An Alarm

Press



and

W

‘Ack’ together.

The action, which now takes place, will depend on the type of latching, which has been configured

Non-Latched Alarms

Alarm condition present when the alarm is acknowledged.

•

ALM beacon on continuously.

•

The alarm message(s) will continue to scroll

This state will continue for as long as the alarm condition remains. When the alarm condition disappears all indication also disappears.

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 acknowledged or the alarm is no longer present.

If the alarm condition disappears before it is acknowledged the alarm resets immediately.

Latched Alarms

See description in section 10.1.


Power Fail Alarm

Alarm condition is indicated when the indicator is switched on.

It is reset using ‘Ack’ buttons

10.1.4 Pre-Alarms

A pre-alarm can be attached to High and Low alarms.

A pre alarm is activated when the PV exceeds a level set as an offset from the ALARM SETPOINT. In this way it always activates a set number of units before the ALARM SETPOINT is reached. It is used to activate a relay, see sections 8.3.2 and 10.1.1.

For example, assume a high alarm setpoint is 400 and the pre-alarm setpoint is 100 then the pre-alarm will activate when the PV = 300.

PV

HIGH ALARM SETPOINT 400 q

PRE ALARM OFFSET 100 r

For a low alarm set to the same values the pre-alarm will activate at 500.

No message is indicated on the instrument display nor is the ALM beacon activated when a pre-alarm occurs.

However, a digital output (eg relay), attached to the alarm, is activated and the relevant OP beacon will illuminate.



10.2 Behaviour of Alarms After a Power

Cycle

The response of an alarm after a power cycle depends upon the latching type, whether it has been configured to be a blocking alarm, it's state and the acknowledge status of the alarm.

Alarm

ON

Alarm

OFF

Alarm

SP

PV

Power on

The response of active alarms after a power cycle is as follows:

For a non-latching alarm or an event alarm blocking will be re-instated, if configured. If blocking is not configured the active alarm will remain active. If the alarm condition has gone safe during the down time the alarm will return inactive.

For an auto-latching alarm blocking will be reinstated, if configured, only if the alarm had been acknowledged prior to the power cycle. If blocking is not configured or the alarm had not been acknowledged the active alarm will remain active. If the alarm condition has gone safe during the downtime the alarm will return inactive if it had been acknowledged prior to the power cycle else it will return safe but not acknowledged. If the alarm was safe but not acknowledged prior to the power cycle the alarm will return safe but not acknowledged.

For a manual-latching alarm blocking will not be reinstated and the active alarm will remain active. If the alarm condition has gone safe during the downtime the alarm will return safe but not acknowledged. If the alarm was safe but not acknowledged prior to the power cycle the alarm will return safe but not acknowledged.

What it means

A change made to a parameter takes a finite time to be entered. If the power to the indicator is turned off before the change has been entered then this alarm will occur.

Do not turn the power off to the indicator while

ConF is flashing

Calibration error

EEPROM error

Non-vol memory error

Invalid input type. This refers to custom linearisation which may not have been applied correctly or may have been corrupted.

What to do about it

Enter configuration mode then return to the required operating mode. It may be necessary to re-enter the parameter change since it will not have been entered in the previous configuration.

Re-instate Factory calibration

Return to factory for repair

Note the error and contact your supplier

Go to the INPUT list in configuration level and set a valid thermocouple or input type

12. Digital Communications

Digital Communications (or ‘comms’ for short) allows the indicator to communicate with a PC or a networked computer system.

This product conforms to MODBUS RTU ® protocol a full description of which can be found on www.modbus.org.

Two ports are available both using MODBUS RTU communication facilities:

1. a configuration port - intended to communicate with a system to download the instrument parameters and to perform manufacturing tests and calibration

2. an optional EIA232 or EIA 485 port on terminals

HD, HE and HF - intended for field communications using, for example, a PC running a SCADA package.

The two interfaces cannot operate at the same time.

For a full description of digital communications protocols (ModBus RTU) refer to the 2000 series

Communications Handbook, part number

HA026230, available on www.eurotherm.co.uk

.

Each parameter has its own unique ModBus address.

A list of these is given at the end of this section.

12.1 Digital Communications Wiring

12.1.1 EIA 232

To use EIA 232 the PC will be equipped with an EIA

232 port, usually referred to as COM 1.

To construct a cable for EIA 232 operation use a three core screened cable.

The terminals used for EIA 232 digital communications are listed in the table below. Some

PC's use a 25 way connector although the 9 way is more common.

These are the functions normally assigned to socket pins. Please check your PC manual to confirm.

12.1.2 EIA 485

To use EIA 485, buffer the EIA 232 port of the PC with a suitable EIA 232/RS485 converter. The Eurotherm

Controls KD485 Communications Adapter unit is recommended for this purpose. The use of a EIA 485 board built into the computer is not recommended since this board may not be isolated, which may cause noise problems, and the RX terminals may not be biased correctly for this application.

To construct a cable for EIA 485 operation use a screened cable with one (EIA 485) twisted pair plus a separate core for common. Although common or screen connections are not necessary, their use will significantly improve noise immunity.

The terminals used for EIA 485 digital communications are listed in the table below.

12.2.1 Broadcast Communications

Broadcast master communications, as a simple master, allows the 3200i indicator to send a single value to any number of slave instruments. Modbus broadcast using function code 6 (Write single value) must be used. This allows the 3200i to link with other products, without the need for a supervisory PC, to create a small system solution. The facility provides a simple and precise alternative to analogue retransmission.

The retransmitted parameter is Process Variable. The indicator will cease broadcast when it receives a valid request from a Modbus master - this allows iTools to be connected for commissioning purposes.

!

Warning

When using broadcast master communications, bear in mind that updated values are sent many times a second. Before using this facility, check that the instrument to which you wish to send values can accept continuous writes. Note that in common with many third party lower cost units, the Eurotherm

2200 series and the 3200 series prior to version

V1.10 do not accept continuous writes to the temperature setpoint. Damage to the internal nonvolatile memory could result from the use of this function. If in any doubt, contact the manufacturer of the device in question for advice.

When using the 3200 series controllers fitted with software version 1.10 and greater, use the Remote

Setpoint variable at Modbus address 26 if you need to write to a temperature setpoint. This has no write restrictions and may also have a local trim value applied. There is no restriction on writing to the 2400 or 3500 series.

12.2.2 Broadcast Master Communications

The 3200 broadcast master can be connected to up to

31 slaves if no segment repeaters are used. If repeaters are used to provide additional segments, 32 slaves are permitted in each new segment. The master is configured by setting the ‘RETRAN’ parameter to PV.

Once the function has been enabled, the instrument will send this value out over the communications link every control cycle (250ms).

Notes:-

1. The parameter being broadcast must be set to the same decimal point resolution in both master and slave instruments.

2. If iTools, or any other Modbus master, is connected to the port on which the broadcast master is enabled, then the broadcast is temporarily inhibited. It will restart approximately

30 seconds after iTools is removed. This is to allow reconfiguration of the instrument using iTools even when broadcast master communications is operating.

12.4 DATA ENCODING

☺

Note that the Eurotherm iTools OPC server provides a straightforward means of accessing any variable in the 3200 indicator in the correct data format without the need to consider data representation. However, if you wish to write your own communications interface software, you will need to take the format used by the 3200 comms software into account.

Modbus data is normally encoded into a 16 bit signed integer representation.

Integer format data, including any value without a decimal point or represented by a textual value (for example ‘off’, or ‘on’), is sent as a simple integer value.

For floating point data, the value is represented as a

‘scaled integer’, in which the value is sent as an integer which gives the result of the value multiplied by 10 to the power of the decimal resolution for that value.

This is easiest to understand by reference to examples:

FP Value

FP Value Integer Representation

Integer Representation

9. 9

-1.0 10

123.5 1235

9.99 999

It may be necessary for the Modbus master to insert or remove a decimal point when using these values.

It is possible to read floating point data in a native 32 bit IEEE format. This is described in the Eurotherm

Series 2000 Communications Handbook (HA026230),

Chapter 7.

13. Calibration

All ranges are calibrated during manufacture to traceable standards for every input type. When changing ranges it is not necessary to calibrate the indicator. Furthermore, the use of a continuous automatic zero correction of the input ensures that the calibration of the instrument is optimised during normal operation.

To comply with statutory procedures such as the Heat

Treatment Specification AMS2750, the calibration of the instrument can be verified and re-calibrated if considered necessary in accordance with the instructions given in this chapter.

For example AMS2750 states:-

"Instructions for calibration and recalibration of ‘field test instrumentation’ and ‘control monitoring and recording instrumentation’ as defined by the NADCAP

Aerospace Material Specification for pyrometry

AMS2750D clause 3.2.5 (3.2.5.3 and sub clauses) including Instruction for the application and removal of offsets defined in clause 3.2.4”.

13.1 To Check Input Calibration

The PV Input may be configured as mV, mA, thermocouple or platinum resistance thermometer.

13.1.1 Precautions

Before checking or starting any calibration procedure the following precautions should be taken:-

1. When calibrating mV inputs make sure that the calibrating source output is set to less than 250mV before connecting it to the mV terminals. If accidentally a large potential is applied (even for less than 1 second), then at least one hour should elapse before commencing the calibration.

2. RTD and CJC calibration must not be carried out without prior mV calibration.

3. A pre-wired jig built using a spare instrument sleeve may help to speed up the calibration procedure especially if a number of instruments are to be calibrated.

4. Power should be turned on only after the instrument has been inserted in the sleeve of the pre-wired circuit. Power should also be turned off before removing the instrument from its sleeve.

5. Allow at least 10 minutes for the instrument to warm up after switch on.

13.1.2 To Check mV Input Calibration

The input may have been configured for a process input of mV, Volts or mA and scaled in Level 3 as described in section 7. The example described in section 7.1.4.1 assumes that the display is set up to read 2.0 for an input of 4.000mV and 500.0 for an input of 20.000mV.

To check this scaling, connect a milli-volt source, traceable to national standards, to terminals V+ and V- using copper cable as shown in the diagram below. mV

Ensure that no offsets (see sections 7.1.3 and 13.2) have been set in the indicator.

Set the mV source to 4.000mV. Check the display reads 2.0 +0.25% + 1LSD (least significant digit).

Set the mV source to 20.000mV. Check the display reads 500.0 +0.25% + 1LSD.

13.1.3 To Check Thermocouple Input Calibration

Connect a milli-volt source, traceable to national standards, to terminals V+ and V- as shown in the diagram below. The mV source must be capable of simulating the thermocouple cold junction temperature. It must be connected to the instrument using the correct type of thermocouple compensating cable for the thermocouple in use.

Adjust the mV source to the minimum range. For a type J thermocouple, for example, the minimum range is -210

O

C. However, if it has been restricted using the Range Low parameter then set the mV source to this limit. Check that the reading on the display is within +0.25% of minimum range + 1LSD.

Adjust the mV source for to the maximum range. For a type J thermocouple, for example, the maximum range is 1200

O

C. However, if it has been restricted using the Range High parameter then set the mV source to this limit. Check that the reading on the display is within +0.25% of maximum range + 1LSD.

Intermediate points may be similarly checked if required.


13.1.4 To Check RTD Input Calibration

Connect a decade box with total resistance lower than

1K and resolution to two decimal places in place of the RTD as indicated on the connection diagram below before the instrument is powered up. If at any instant the instrument was powered up without this connection then at least 10 minutes must elapse from the time of restoring this connection before RTD calibration check can take place.

13.2 Offsets

The process value can be offset to take into account known errors within the process. The offset can be applied to any Input Type (mV, V, mA, thermocouple or RTD).

A single offset can be applied - the procedure is carried out in the INPUT list and has been described in section 7.1.3.

It is also possible to adjust the low and high points as a five point offset. This can only be done in Level 3 in the ‘Cal ’ list and is described below.

13.2.1 Five Point Offset

A five point offset may be used to compensate for transducer or measurement non-linearities. The diagram shows an example of the type of discontinuity which might occur in a system.

In this case adjust each point in turn for the VALUE

WHICH THE INDICATOR SHOULD READ. For example if the value at point 1 should be 1.2345 then set Pnt.1 to this value. The following example shows how to do this.

Do This

1. Select Level 3 as described in Chapter 2.

Note:-

The calibration points must be chosen consecutively – the five point calibration will not work if a higher point is inserted between other points.

13.3 Input Calibration

If the calibration is not within the specified accuracy follow the procedures in this section:-

In 3200 series instruments, inputs which can be calibrated are:-

• mV Input. This is a linear 80mV range calibrated at two fixed points. This should always be done before calibrating either thermocouple or resistance thermometer inputs. mA range calibration is included in the mV range.

• Thermocouple calibration involves calibrating the temperature offset of the CJC sensor only. Other aspects of thermocouple calibration are also included in mV calibration.

• Resistance Thermometer. This is also carried out at two fixed points - 150 Ω and 400Ω.

The precautions stated in section 13.1.1 should be observed.

14. Configuration Using iTools

iTools is a configuration and monitoring package which will edit, store and ‘clone’ complete instrument configurations. iTools can be used to configure all the functions of the 3000 series indicators described in this manual.

It is also possible using iTools to configure additional functions such as customised messages and parameter promotion. These features are described in this chapter.

You may also wish to refer to the iTools Help Manual

Part No. HA028838 which can be downloaded from www.eurotherm.co.uk

. for further information on how to install, connect and generally operate iTools.

14.1 Loading an IDM

An IDM is a software file which defines the parameter addresses of a particular build of instrument. This is normally included with your iTools CD and iTools will then recognize the software version of your instrument. Alternatively, download the latest version of iTools. This may be found in www.eurotherm.co.uk.

If the build of your instrument is a non-standard, it may be necessary for you to download the IDM from the Eurotherm web site. The file will be of the format id32i_v107.exe, where id 32i is the instrument and V--

- is the software version number of the instrument.

To load the IDM

From windows START., select Programs → Eurotherm iTools → Advanced Tools → IDM Manager. Then

Install New IDM.

To register the new IDM

Copy the file to c:\Program

Files\Eurotherm\iTools\Devices.


14.2 Connecting a PC to the Indicator

This may be done using digital communications port

H or by a configuration clip.

Select input type from the drop down. Other parameters can also be set using the drop downs or by setting the analogue values.

Parameters shown in blue, in the iTools view, are not alterable.

14.5.2 To Configure Alarms

1. Select the list header from the browser – in this case ‘ALARM’ ‘1’

2. To configure ‘Alarm

Type’ open the drop down under the

‘Value’ column

4. Select the alarm type

– in this example HI.

(1) is the enumeration of the parameter.

5. Select and set all other parameters using the same procedure



14.5.3 To Customise Messages

In this example the alarm 1 message will read ‘TOO HOT’.

1. Press and select the ‘Message Table’ tag

2. Select Parameter ‘ALARM1 #1’

3. In the ‘Message Condition’ area change ‘Message’ to SHUT DOWN

4. Press ‘Update Device Flash Memory’ button

14.5.4 To Promote Parameters

In this example the parameter ‘OP1.Sense’ is added to the to the Level 2 list.

1. Press and select the ‘Promote Parameters’ tab

2. Highlight the position where you want the new parameter to be placed

3. Press button and from the pop up window select the required parameter

4. In the Level box select Level 2 (or Level 1 + 2 if it is required to display this parameter in Level 1 as well)

5. In the Access box select ‘Read Only’ or ‘Read/Write’ as required

6. Press to remove a selected parameter

7. Press ‘Update Device Flash Memory’ button




14.6 To Load A Special Linearisation Table

In addition to the built in standard linearisation tables, custom tables can be downloaded from files.

1. Press

2. Select the lineariastion table to be loaded from files with the extension .mtb. Linearisation files for different sensor types are supplied with iTools and may be found in Program Files ¤ Eurotherm ¤ iTools ¤

Linearisations ¤ Thermocouple etc.

3. In this example a Pt-PTRh(10%) thermocouple has been loaded into the indicator. The indicator will display the linearisation table downloaded:-



14.7 To Set up Recipes

14.7.1 Example:- Set Two Different Alarm Thresholds and Store in Recipes 1 and 2

1. Set an alarm threshold e.g 300.

2. Select ‘RECIPE’ in the browser

3. In RecipeSave, select the recipe number e.g. 1

4. Set the alarm threshold to another value and save in Recipe 2

5. In RecipeNumber choose the recipe to run. Recipe 1 will now select the first alarm threshold and recipe 2 will select the second alarm threshold.

It may be more convenient to open more than one parameter list as shown in the above view. To do this, double click on each list header in turn. The lists can be arranged using Window in the main menu and choose Tile

Vertically, Tile Horizontally or Cascade.



14.8 Summary

Press to display the terminal connections for the functions which have been configured together with a summary of each function.

A summary of the features configured may be selected using the ‘Summary’ tab.



14.9 Cloning

The cloning feature allows the configuration and parameter settings of one instrument to be copied into another.

Alternatively a configuration may be saved to file and this used to download to connected instruments. The feature allows new instruments to be rapidly set up using a known reference source or standard instrument. Every parameter and parameter value is downloaded to the new instrument which means that if the new instrument is used as a replacement it will contain exactly the same information as the original. Cloning is generally only possible if the following applies:

•

The target instrument has the same hardware configuration as the source instrument

•

The target instrument firmware (ie. Software built into the instrument) is the same as or a later version than that of the source instrument. The instrument firmware version is displayed on the instrument when power is applied.

•

Generally, cloning will copy all operational, engineering and configuration parameters that are writable. The communications address is not copied.

!

Every effort has been made to ensure that the information contained within the clone files is a replica of that configured in the instrument. It is the users responsibility to ensure that the information cloned from one instrument to another is correct for the process to be controlled, and that all parameters are correctly replicated into the target instrument.

Below is a brief description of how to use this feature. Further details are available in the iTools Handbook

14.9.1 Save to File

The configuration of the indictor made in the previous sections may be saved as a clone file. This file can then be used to download the configuration to further instruments.

From the File menu use ‘Save to File’ or use the ‘Save’ button on the Toolbar.

14.9.2 To Clone a New Indicator

Connect the new indictor to iTools and Scan to find this instrument as described at the beginning of this chapter.

From the File menu select ‘Load Values From File’ or select ‘Load’ from the toolbar. Choose the required file and follow the instruction. The new instrument will be configured to this file.
