1. Installation and Basic Operation

1.1 What Instrument Do I Have? Thank you for choosing this 3200 series Temperature Controller/Programmer.

The 3200 series provide precise temperature control of industrial processes and is available in three standard DIN sizes:-

• 1/16 DIN Model Number 3216

• 1/8 DIN Model Number 3208 • 1/8 DIN Horizontal Model Number 32h8 • 1/4 DIN Model Number 3204

A universal input accepts various thermocouples, RTDs or process inputs. Up to three (3216) or four (3208, 32h8 and 3204) outputs can be configured for control, alarm or re-transmission purposes. Digital communications and a current transformer input are available as options.

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.

The last two sets of five digits show the Quick Start Code.

If the Quick Start Code shows *****/***** the controller was supplied with default parameters and will need to be configured when it is first switched on.

This Manual takes you through all aspects of installation, wiring, configuration and use of the controller.

1.2 Unpacking Your Controller The controller is supplied with:-

• Sleeve (with the controller fitted in the sleeve)

• Two panel retaining clips and IP65 sealing gasket mounted on the sleeve

• Component packet containing a snubber for each relay output (see section 2.11) and a 2.49Ω resistor for current inputs (see section 2.6)

• Installation sheet Part Number HA029714

1.3 Dimensions General views of the controllers are shown below together with overall dimensions.

1.4 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 the ambient temperature is within 0 and 55oC (32 - 131oF) and humidity 5 to 95% RH non condensing.

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 3 before proceeding. The EMC Booklet part number HA025464 gives further installation information.

1.4.1 Panel Mounting the Controller

1. Prepare a cut-out in the mounting panel to the size shown. If a number of controllers 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 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.

1.4.2 Panel Cut Out Sizes

1.4.3 Recommended minimum spacing of controllers

Applies to all models.

1.4.4 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

2.4 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).

2.5 Precautions • Do not run input wires together with power cables • 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

• Not isolated from the logic outputs & digital inputs • Pay attention to line resistance; a high line resistance

may cause measurement errors

2.11 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 series connected resistor/capacitor (typically 15nF/100Ω). 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, 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.

2.12 Digital Inputs A & B Digital input A is an optional input in all 3200 series controllers. Digital input B is always fitted in models 3208, 32h8 and 3204, but is not available in 3216.

• Not isolated from the current transformer input or the sensor input

• Switching: 12Vdc at 40mA max • Contact open > 500Ω. Contact closed < 200Ω • Input functions: Please refer to the list in the quick

codes.

☺ If EIA232 digital communications is fitted (3216 only), Digital Input A is not available.

2.13 Current Transformer The current transformer input is an optional input in all 3200 series controllers.

☺ If EIA232 digital communications is fitted (3216 only), Current Transformer Input is not available.

It can be connected to monitor the rms current in an electrical load and to provide load diagnostics. The following fault conditions can be detected: SSR (solid state relay) short circuit, heater open circuit and partial load failure. These faults are displayed as alarm messages on the controller front panel.

Note: C terminal is common to both the CT input and Digital input A. They are, therefore, not isolated from each other or the PV input.

• CT input current: 0-50mA rms (sine wave, calibrated) 50/60Hz

• A burden resistor, value 10Ω, is fitted inside the controller.

• It is recommended that the current transformer is fitted with a voltage limiting device to prevent high voltage transients if the controller is unplugged. For example, two back to back zener diodes. The zener voltage should be between 3 and 10V, rated at 50mA.

• CT input resolution: 0.1A for scale up to 10A, 1A for scale 11 to 100A

• CT input accuracy: +4% of reading.

2.14 Transmitter Power Supply The Transmitter Supply is not available in the Model 3216. It is fitted as standard in the Models 3208, 32h8 and 3204.

• Isolated output 240Vac CAT II • Output: 24Vdc, +/- 10%. 28mA max. • inside the controller

2.15.1.1 EIA422 Connections (3216 only)

☺ If EIA422 serial communications is fitted, the CT and LA digital input option is not possible since EIA422 shares the same terminals as the CT and LA.

☺ The KD485 communications converter is recommended for: • Interfacing 4-wire to 2-wire connections. • To buffer an EIA422/485 network when more than

32 instruments on the same bus are required • To bridge 2-wire EIA485 to 4-wire EIA422.

3. Safety and EMC Information 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.

Safety This controller complies with the European Low Voltage Directive 73/23/EEC, by the application of the safety standard EN 61010.

Electromagnetic compatibility This controller conforms with the essential protection requirements of the EMC Directive 89/336/EEC, 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 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 -30oC to +75oC.

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

Caution: Charged capacitorsBefore 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 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.

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 controller. They have the following meaning:

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 controller must be enclosed 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.

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.

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

! Caution, (refer to accompanying documents)

Equipment protected throughout by DOUBLE INSULATION

3200 Series

16 Part No HA028651 Issue 7.0 Apr-09

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.

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)

The rated impulse voltage for equipment on nominal 230V supply 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 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

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.

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.

• 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.

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.

4.2 To Re-Enter Quick Code mode If you need to re-enter the ‘Quick Configuration’ mode this can always be done as follows:-

1. Power down the controller 2. Hold down the button, and power up the

controller again. 3. Keep the button pressed until code is displayed. 4. Enter the configuration code (this is defaulted to 4

in a new controller) 5. The quick start codes may then be set as described

previously

Parameters may also be configured using a deeper level of access. This is described in later chapters of this handbook.

☺ If the controller is started with the button held down, as described above, and the quick start codes are shown with dots (e.g. J.C.X.X.X), this indicates that the controller has been re-configured in a deeper level of access and, therefore, the quick start codes may not be valid. If the quick start codes are accepted by scrolling

to then the quick start codes are reinstated.

4.3 Pre-Configured Controller or Subsequent Starts A brief start up sequence consists of a self test during which the software version number is shown followed briefly by the quick start codes.

It will then proceed to Operator Level 1..

You will see the display shown below. It is called the HOME display.

☺ If the quick start codes do not appear during this start up, it means that the controller has been configured in a deeper level of access, see the note in section 4.2. The quick start codes may then not be valid and are therefore not shown.

Operator Buttons:- From any view -press to return to the HOME display Press to select a new parameter. If held down it will continuously scroll through parameters. Press to decrease a value Press to increase a value

4.4.1 To Set The Target Temperature.

From the HOME display:-

Press to raise the setpoint

Press to lower the setpoint

The new setpoint is entered when the button is released and is indicated by a brief flash of the display.

4.4.2 Alarms Process alarms may be configured using the Quick Start Codes section 4.1.1. Each alarm can be configured for:-

Full Scale Low The alarm is shown if the process value falls below a set threshold

Full Scale High The alarm is shown if the process value rises above a set threshold

Deviation Low The alarm is shown if the process value deviates below the setpoint by a set threshold

Deviation High The alarm is shown if the process value deviates above the setpoint by a set threshold

Deviation Band The alarm is shown if the process value deviates above or below the setpoint by a set threshold

If an alarm is not configured it is not shown in the list of level 2 parameters, section 5.3

Additional alarm messages may be shown such as CONTROL LOOP BROKEN. This occurs if the controller does not detect a change in process value following a change in output demand after a suitable delay time.

Another alarm message may be INPUT SENSOR BROKEN (SBr). This occurs if the sensor becomes open circuit; the output level will adopt a ‘SAFE’ value which can be set up in Operator Level 3, see section 11.10.

☺ From firmware version 2.11 two further alarm types have been made available. These are:-

Rising rate of change

An alarm will be detected if the rate of change (units/minute) in a positive direction exceeds the alarm threshold

Falling rate of change

An alarm will be detected if the rate of change (units/minute) in a negative direction exceeds the alarm threshold

These alarms cannot be configured by the Quick Start Code – they can only be configured in Configuration Mode, see section 12.3.

4.4.3 Alarm Indication If an alarm occurs, the red ALM beacon will flash. A scrolling text message will describe the source of the alarm. Any output (usually a relay) attached to the alarm will operate. An alarm relay can be configured using the Quick Start Codes to be energised or de- energised in the alarm condition. It is normal to configure the relay to be de-energised in alarm so that an alarm is indicated if power to the controller fails.

Press and (ACK) together to acknowledge

If the alarm is still present the ALM beacon will light continuously otherwise it will go off.

The action which takes place depends on the type of alarm configured:-

Non latching

A non latching alarm will reset itself when the alarm condition is removed. By default alarms are configured as non- latching, de-energised in alarm.

Auto Latching

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

Manual Latching

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.

By default alarms are configured as non-latching, de- energised in alarm. To configure latched alarms, refer to section 12.3.1.

4.4.4 Auto, Manual and Off Mode

The controller can be put into Auto, Manual or Off mode – see next section.

Auto mode is the normal operation where the output is adjusted automatically by the controller in response to changes in the measured temperature.

In Auto mode all the alarms and the special functions (auto tuning, soft start, timer and programmer) are operative

Manual mode means that the controller output power is manually set by the operator. The input sensor is still connected and reading the temperature but the control loop is ‘open’.

In manual mode the MAN beacon will be lit, Band and deviation alarm are masked, the auto-tuning timer and programmer functions are disabled.

The power output can be continuously increased or decreased using the orbuttons.

! Manual mode must be used with care. The power level must not be set and left at a value that can damage the process or cause over-heating. The use of a separate ‘over-temperature’ controller is recommended.

Off mode means that the heating and cooling outputs are turned off. The process alarm and analogue retransmission outputs will, however, still be active while Band and deviation alarm will be OFF.

4.4.5 To Select Auto, Manual or Off Mode

Press and hold and (Mode) together for more than 1 second.

This can only be accessed from the HOME display.

1. Auto’ is shown in the upper display. After 5 seconds the lower display will scroll the longer description of this parameter. ie ’loop mode – auto manual off ’

2. Press to select ‘mAn’. Press again to select ‘OFF’. This is shown in the upper display.

3. When the desired Mode is selected, do not push any other button. After 2 seconds the controller will return to the HOME display.

4. If OFF has been selected, OFF will be shown in the lower display and the heating and cooling outputs will be off

5. If manual mode has been selected, the MAN beacon will light. The upper display shows the measured temperature and the lower display the demanded output power.

☺ The transfer from Auto to manual mode is ‘bumpless’. This means the output will remain at the current value at the point of transfer. Similarly when transferring from Manual to Auto mode, the current value will be used. This will then slowly change to the value demanded automatically by the controller.

6. To manually change the power output, press or to lower or raise the output. The output power is continuously updated when these buttons are pressed

7. To return to Auto mode, press and together. Then press to select ‘Auto’.
