INTRODUCTION

The Model 2216e is a precision temperature controller with self tuning. It has a modularhardware construction which provides two control outputs, one alarm relay and onecommunications port.

Controller labels

The labels on the sides of the controller identify the ordering code, the serial number, and thewiring connections.

Appendix A, Understanding the Ordering Code explains the hardware and softwareconfiguration of your particular controller.

MECHANICAL INSTALLATION

To install the controller

1. Cut the panel to the relevant hole size shown in Figure 2-3 and 2.4.

2. Insert the controller through the front of this cutout.

3. Spring the upper and lower panel retaining clips into place. Secure the controller inposition by holding it level and pushing both retaining clips forward.

If the panel retaining clips subsequently need removing, they can be unhooked fromthe side with either your fingers or a screwdriver

Unplugging and plugging-in the controller

The controller can be unplugged from its sleeve by easing the latching ears outwards andpulling it forward out of the sleeve. When plugging the controller back into its sleeve, ensurethat the latching ears click into place to maintain the IP 65 sealing.

NOTE



WIRING

Please read Appendix B, Safety and EMC information before proceeding.

WARNINGPlease ensure that the controller is correctly configured for your application.Incorrect configuration could result in damage to the process being controlled,and/or personal injury. The controller may either have been configured whenordered, or may need configuring now. See Chapter 5, Configuration.

Figure 2-3 Model 2216e wiring connections

* The ground connection is not required for electrical safety but must be connected to satisfyEMC requirements.

Wire Sizes

All electrical connections are made to the screw terminals at the rear of the controller. Theyaccept wire sizes from 0.5 to 1.5 mm2 (16 to 22 AWG), and are protected by a hinged cover toprevent hands or metal making accidental contact with live wires. Rear terminals should betightened to a torque of 0.4Nm (3.5 lb in).

Wiring connections

The wiring connections are shown in Figure 2-3.Outputs 1 and 2 are factory fitted modules which can be any one of the types shown in figure2-8. Check the ordering code on the controller side label to determine which have been fitted.

NOTE



PDSIO® modes

PDSIO® is a proprietary technique developed by Eurotherm for bi-directional communicationover a single pair of wires. There are several operating modes. In SSRx Load Doctor a logic output delivers a power demand signal to a TE10 solid staterelay (SSR) and the SSR responds with a single load circuit failure message.In SSRx Enhanced Load Doctor a logic output delivers a power demand signal to an SSRand the SSR responds with the ON state RMS load current, and two fault messages - SSRfailure or heater circuit failure.

Snubbers

The controller is supplied with ‘snubbers’ (15nF +100Ω) which should be wired across therelay or triac outputs when switching inductive loads such as mechanical contactors andsolenoid valves. The snubbers are used to prolong contact life and to suppress interferencewhen switching such loads.Snubbers pass 0.6mA at 110Vac and 1.2mA at 240Vac, which may be sufficient to hold inhigh impedance relay coils. They should not, therefore, be used in such installations.

WARNINGWhen a relay contact is used in an alarm circuit ensure that the current passing throughthe snubber when the relay contact is open does not hold in low power electrical loadsand thereby interfere with the failsafe operation of the alarm circuit.

COMMUNICATION CONNECTIONS

The communication option can be either of four types shown in the table below

Access Levels Installation and Operation Handbook


This chapter describes the different levels of access to the operating parameters within the2208e and 2204e controller.

There are three topics:

• THE DIFFERENT ACCESS LEVELS

• SELECTING AN ACCESS LEVEL

• EDIT LEVEL

THE DIFFERENT ACCESS LEVELS

Access level Displayshows

What you can do PasswordProtection

Operator In this level operators can view and adjust thevalue of parameters defined in Edit level (seebelow).

No

Full In this level all the parameters relevant to aparticular configuration are visible. Allalterable parameters may be adjusted.

Yes

Edit In this level you can set which parameters anoperator in Operator level is able to view andadjust. You can hide or reveal complete listsand individual parameters within each list, andyou can make parameters read-only oralterable. You can also promote parametersto the home list. (See Edit level at the end ofthe chapter).

Yes

Configuration This special level allows access to set up thefundamental characteristics of the controller.

Yes

Figure 3-1 Access levels



SELECTING AN ACCESS LEVEL

Access to Full, Edit or Configuration levels is protected by a password to preventunauthorised access.If you need to change the password, see Chapter 5, Configuration

Access list header

Press until you reach the access list header ‘’.

Press the Scroll button

Password entry

The password is entered from the ‘ display.

Enter the password using the or buttons. Once

the correct password has been entered, there is a two second delayafter which the lower readout will change to show ‘indicating that access is now unlocked.The pass number is set to ‘1’ when the controller is shipped fromthe factory.

Note; A special case exists if the password has been set to ‘’. Inthis case access will be permanently unlocked and the lowerreadout will always show ‘’

Press the Scroll button to proceed to the display.

(If an incorrect password has been entered and the controller is still‘locked’ then pressing Scroll at this point will simply return you tothe list header.)

Note: From this display, you can access “read only”configuration level by pressing and together.

To escape, press and together.



.

.

Level selection

The display allows you to select the requiredaccess level.

Use and to select from the following displaycodes: Operator level

: Full level Edit level: Configuration level


If you selected either ‘, or level youwill be returned to the ‘ list header in the level thatyou chose. If you selected ‘’, you will get analternative display showing ‘’ in the upper readout(see below).

Configuration password

When the ‘’ display appears, you must enter theConfiguration password in order to gain access toConfiguration level. Do this by repeating the passwordentry procedure described in the previous sectionThe configuration password is set to ‘’ when thecontroller is shipped from the factory. If you need tochange the configuration password, see Chapter 5,Configuration


Configuration level

The first display of configuration is shown. See chapter5, Configuration for details of the configurationparameters.For instructions on leaving configuration level seeChapter 5, Configuration.



Returning to Operator Level

To return to operator level from either ‘’ or ‘’ level, repeat entry of the passwordand select ‘’ on the ’’ display.In ‘Edit’ level the controller will automatically return to operator level if no button is pressedfor 45 seconds.

EDIT LEVEL

Edit level is used to set which parameters you can see and adjust in Operator level. It alsogives access to the ‘Promote’ feature which allows you to select and add (‘Promote’) up totwelve parameters into the Home display list, thereby giving simple access to commonly usedparameters.

Setting operator access to a parameter

First you must select level, as shown on the previous page.Once in level you select a list or a parameter within a list in the same way as you wouldin Operator or Full level. Τhat is, you move from list header to list header by pressing thePage button, and from parameter to parameter within each list using the Scroll button.However, in Edit level what is displayed is not the value of a selected parameter but a coderepresenting the parameter’s availability in Operator level.

When you have selected the required parameter, use the and buttons to set itsavailability in operator level.There are four codes: Makes a parameter alterable in Operator level Promotes a parameter into the Home display list Makes a parameter or list header read-only (it can be viewed but not altered) Hides a parameter or list header.For example:

The parameter selected is the set point for Alarm2 - Full Scale Low

It will be alterable in Operator level



Hiding or revealing a complete list

To hide a complete list of parameters, all you have to do is hide the list header. If a list headeris selected only two selections are available: and .(It is not possible to hide the ‘’ list which will always display the code: ‘’.)

Promoting a parameter

Scroll through the lists to the required parameter and choose the ‘’ code. The parameter isthen automatically added (promoted) into the Home display list (the parameter will also beaccessible as normal from the standard lists. a maximum of 16 parameters can be promoted.Promoted parameters are automatically ‘alterable’.

Tuning Installation and Operation Handbook


Before tuning please read Chapter 1, Operation, to learn how to select and change aparameter.

This chapter has three main topics:

• WHAT IS TUNING?

• AUTOMATIC TUNING

• MANUAL TUNING

WHAT IS TUNING?

In tuning you match the characteristics of the controller to that of the process being controlledin order to obtain good control. Good control means:

Stable ‘straight-line’ control of the temperature at setpoint without fluctuation

Acceptable overshoot or undershoot of the temperature setpoint

Quick response to deviations from the setpoint caused by external disturbances, therebyrestoring the temperature rapidly to the setpoint value.

Tuning involves calculating and setting the value of the parameters listed in Table 4-1. Theseparameters appear in the list.

Parameter Code Meaning or Function

Proportionalband

The bandwidth in display units over which the output power isproportioned between minimum and maximum.

Integral time Determines the time taken by the controller to remove steady-state error signals.

Derivativetime

Determines how strongly the controller will react to the rate-of-change of the measured value.

Low cutback The number of display units below setpoint at which thecontroller will cutback the output power in order to preventovershoot on heat up.

High Cutback The number of display units above setpoint at which thecontroller will increase the output power in order to preventundershoot on cool down.

Relative coolgain

Only present if cooling has been configured. Sets the coolingproportional band by dividing the Pb value by the rEL.C value.

Table 4-1 Tuning parameters



AUTOMATIC TUNING

This method automatically determines the value of the parameters listed in table 4-1 on theprevious page.

The 2216e uses a ‘one-shot’ tuner which works by switching the output on and off to inducean oscillation in the measured value. From the amplitude and period of the oscillation, itcalculates the tuning parameter values.

If the process cannot tolerate full heating or cooling being applied during tuning, then thelevel of heating or cooling can be restricted by setting the heating and cooling power limits inthe Output list. However, the measured value must oscillate to some degree for the tuner to beable to calculate values

A One-shot Tune can be performed at any time but normally it is performed only once duringthe initial commissioning of the process. However, if the process under control subsequentlybecomes unstable (because its characteristics have changed), you can re-tune again for the newconditions.

It is best to start tuning with the process at ambient temperature. This allows the tuner tocalculate more accurately the low cutback and high cutback values that restrict the amount ofovershoot or undershoot.

Heating and Cooling Output Cycle Times

Before commencing a tuning cycle, set the values of (heat cycle time) and (coolcycle time) in the op (output list). These values apply if you are using a logic, relay or triacoutput. They have no effect on a DC output.

A logic output switching a solid state relay can be set to values such as 1 sec.

A relay or triac output should be set to 20 sec.



How to tune

1. Set the setpoint to the value at which you will normally operate the process.

2. In the ‘’ list, select ‘’ and set it to ‘ ’

3. Press the Page and Scroll buttons together to return to the Home display. The displaywill flash ‘’ to indicate that tuning is in progress.

4. The controller will induce an oscillation in the temperature by turning the heating on andthen off. The first cycle will not complete until the measured value has reached therequired setpoint.

5. After two cycles of oscillation the tuning will be completed and the tuner will switchitself off.

6. The controller will then calculate the tuning parameters listed in Table 4-1 and willresume normal control action.

If you want ‘Proportional only’ or ‘PD’ or ‘PI’ control, you should set the ‘’ or ‘’parameters to before commencing the tuning cycle. The tuner will leave them off andwill not calculate a value for them.

For valve position tuning and set-up, please refer to Appendix D.



Typical automatic tuning cycle

Calculation of the cutback values

Low cutback and High cutback are values that restrict the amount of overshoot or undershootthat occur during large step changes in temperature (for example, under startup conditions).

If either low cutback or high cutback is set to ‘ ’ the values will be fixed at three timesthe proportional band, and will not be changed during automatic tuning.

Temperature



MANUAL TUNING

If for any reason automatic tuning gives unsatisfactory results, you can tune the controllermanually. There are a number of standard methods for manual tuning. The one describedhere is the Ziegler-Nichols method.

With the process at its normal running temperature:

1. Set the Integral Time ‘ and the Derivative Time ‘’ to .

2. Set High Cutback and Low Cutback, ‘’ and ‘’, to ‘ ’

3. Ignore the fact that the temperature may not settle precisely at the setpoint

4. If the temperature is stable, reduce the proportional band ‘’ so that the temperature juststarts to oscillate. If the temperature is already oscillating, increase the proportional banduntil it just stops oscillating. Allow enough time between each adjustment for the loop tostabilise. Make a note of the proportional band value ‘B’ and the period of oscillation ‘T’.

5. Set the Pb, ti, td parameter values according to the calculations given in Table 4-2.

Type of control Proportionalband ‘Pb’

Integral time ‘ti’ Derivative time‘td’

Proportional only 2xB OFF OFF

P + I control 2.2xB 0.8xT OFF

P + I + D control 1.7xB 0.5xT 0.12xT

Table 4-2 Tuning values



Setting the cutback values

The above procedure sets up the parameters for optimum steady state control. If unacceptablelevels of overshoot or undershoot occur during start-up or for large step changes intemperature, then manually set the cutback parameters and .

Proceed as follows:

1. Set the low and high cutback values to three proportional bandwidths (that is to say, Lcb= Hcb = 3 x Pb).

2. Note the level of overshoot or undershoot that occurs for large temperature changes (seethe diagrams below).

In example (a) increase by the overshoot value. In example (b) reduce by theundershoot value.

Example (b)

Where the temperature approaches setpoint from above, you can set ina similar manner.

Integrating action and manual resetIn a full three-term controller (that is, a PID controller), the integral term ‘ti’ automaticallyremoves steady state errors from the setpoint. If the controller is set up to work in two-termmode (that is, PD mode), the integral term will be set to . Under these conditions themeasured value may not settle precisely at setpoint. When the integral term is set to OFF theparameter manual reset (code ) appears in the in ‘’ Access level.This parameter represents the value of the power output that will be delivered when the erroris zero. You may set this value manually in order to remove the steady state error.

Automatic droop compensation (Adc)

The steady state error from the setpoint, which occurs when the integral term is set to OFF, issometimes referred to as ‘droop’. automatically calculates the manual reset value inorder to remove this droop. To use this facility, you must first allow the temperature tostabilise. Then, in the autotune parameter list, you must set to ‘’. The controllerwill then calculate a new value for manual reset, and switch to ‘’.

can be repeated as often as you require but between each adjustment you must allow timefor the temperature to stabilise.

This chapter has five topics:

• WHAT IS THE PURPOSE OF USER CALIBRATION?

• USER CALIBRATION ENABLE

• SINGLE POINT CALIBRATION

• TWO POINT CALIBRATION

• CALIBRATION POINTS AND CALIBRATION OFFSETS

To understand how to select and change parameters in this chapter you will need to have readChapter 2 - Operation, Chapter 3- Access Levels and Chapter 5 - Configuration.

WHAT IS THE PURPOSE OF USER CALIBRATION?

The basic calibration of the controller is highly stable and set for life. User calibration allowsyou to offset the ‘permanent’ factory calibration to either:

1. Calibrate the controller to your reference standards

2. Match the calibration of the controller to that of a particular transducer or sensor input

3. Calibrate the controller to suit the characteristics of a particular installation.

User calibration works by introducing zero and span offsets onto the factory set calibration.The factory set calibration can always be retrieved.



USER CALIBRATION ENABLEThe User calibration facility must first be enabled in configuration level by setting theparameter ‘' in the list to ' ' This will make the User calibrationparameters appear in Operator ‘’ level.Select configuration level as shown in Chapter 5, Configuration

SINGLE POINT CALIBRATION

Your controller is calibrated for life against known reference sources during manufacture. Acalibration offset is often used to allow the controller to compensate for sensor and othersystem errors. The normal procedure is to set up the system under test against a knownindependent reference, as follows:Set up the process to be calibrated such that the known reference displays the required value(temperature).Observe the reading on the controller. If it is different, proceed as follows:Select ‘ Access level as described in Chapter 3

Press the Scroll buttoncontinued on the next page



To protect the calibration against unauthorised adjustment return to Operator level and makesure that the calibration parameters are hidden. Parameters are hidden using the ‘’facility describe in Chapter 3.

TWO POINT CALIBRATION

The previous section described how to perform a single point calibration which applies a fixedoffset over the full display range of the controller. A two-point calibration is used to calibratethe controller at two points and apply a straight line between them. Any readings above orbelow the two calibration points will be an extension of this straight line. For this reason it isbest to calibrate with the two points as far apart as possible.

Proceed as follows:

1. Decide upon the low and high points at which you wish to calibrate.

2. Perform a single point calibration at the low calibration point in the mannerdescribed above

3. Set the process under calibration such that the known reference exhibits the requiredhigher Process Value (temperature) and allow to stabilize.

4. Press the Scroll button to obtain the high calibration point as shown in thefollowing diagrams.

Adjust the low point calibration

The controller will display the current measured input value in thelower readout.

Use or to adjust the reading to the reference sourcevalue, if different.After a two second delay the display will blink and the reading willchange to the new, calibrated value. You can calibrate at any pointover the entire display rangeThis is a single point calibration which applies a fixed offset over thefull display range of the controller.The calibration is now complete.

The 2200e series controllers are capable of very sophisticated alarm strategies and, althoughsetting up of alarms has already been covered in previous chapters, this section has beenincluded to enable operators and commissioning engineers to design their own strategies foroptimum plant operation.

Alarm Operation Installation and Operation Handbook


DEFINITION OF ALARMS AND EVENTS

Alarms are used to alert an operator when a pre-set level or condition has been exceeded.They are normally used to switch an output - usually a relay - to provide interlocking of themachine or plant or external audio or visual indication of the condition.

Soft Alarms are indication only within the controller and are not attached to an output (relay).

Events - can also be alarms - but are generally defined as conditions which occur as part of thenormal operation of the process. They do not generally require operator intervention.

Events are referred to as Digital Output Functions in the manual (see Table B, page 5-13).

For the purposes of the operation of this instrument alarms and events can be consideredthe same.

TYPES OF ALARMS

The use of alarms in the 2216econtroller is extremely versatile.Up to 4 alarms can be configured. Any combination of these 4 alarms can be attached to anyone or more available outputs, or any number of the available “soft” alarms can be combinedto operate a single output.

Note: In a three term controller at least one of these outputs is used to maintainthe required temperature of the process.

Outputs 1A and 2A Are plug in modules.Normally used for control outputs, eg. Heat and Cool, but canbe used for alarm outputs.

Output 3A Is a fixed relay.Normally used for alarms or events, but can be used as controloutputs.

NOTE



There are seven process alarm types listed below. Alarm Types are found in configurationmode under the Alarm Config. List.

ALARMS

Full Scale High The PV exceeds a set high level

Full Scale Low The PV exceeds a set low level

Deviation Band The difference between PV & SP is outside a set band

Deviation High The difference between PV & SP is higher than a set level

Deviation Low The difference between PV & SP is lower than a set level

High Current The measured current returned from a PDSIO® slave is higher than aset level

Low Current The measured current returned from a PDSIO® slave is lower than aset level

Each alarm can be set to:

Latching Alarm is indicated until acknowledged(Off, Auto, MAN)

Auto Acknowledge: ( )If the alarm is acknowledged while the alarm condition is stillpresent, it will cause the alarm to reset as soon as the alarmcondition is removed.

Manual Acknowledge: ( )If the alarm is acknowledged while the alarm condition isstill present, it will be ignored. A further acknowledgementis required when the alarm condition has been removed tocause the alarm to reset.

Blocking Alarm occurs after it has been through a start up phase not in alarmcondition.

Sense Of Output Relay energised or de-energised in alarm condition.



In addition there are nine “digital output functions” used as events or alarms depending uponthe requirements of the process under control:

DIGITAL OUTPUT FUNCTIONS

Sensor Break` The input is open circuit

Loop Break The controller does not measure a response to anoutput change

Load Failure Used with PDSIO® Mode 1 load failure

Manual Controller in manual mode

PV Out Of Range Process Variable too high or too low

Remote SP Fail No signal measured at the remote set point input terminals

Heater Fail Used with PDSIO® Mode 2 heater open circuit

SSR Fail Used with PDSIO® Mode 2 solid state relay open or shortcircuit

Program END Signals the end of a program

New Alarm Signals a new alarm

The Sense of the Output can be set to relay energised or de-energised in the alarm conditionfor any of the above functions.

Understanding the Ordering Code Installation and Operation Handbook

A-4 2216e Controller

Notes:

1. PDSIO® is a proprietary technique developed by Eurotherm for bi-directionalcommunication over a single pair of wires. There are several operating modes.

In SSRx Load Doctor a logic output delivers a power demand signal toa TE10 solid state (SSR) relay and the SSR responds with a single loadcircuit failure message. Also called SSRx Load Doctor.

In SSRx Enhanced Load Doctor a logic output delivers a powerdemand signal to an SSR and the SSR responds with the ON state rmsload current, and two fault messages - SSR failure or heater circuitfailure. Also called SSRx Enhanced Load Doctor.

2. Range min and Range max: Enter a numeric value, with a decimal point if required.Thermocouple and RTD sensor inputs will always display over the full operating rangeshown in the sensor input table. The values entered here will act as limits for the setpointhigh and low limit parameters and for alarm setpoints.

3. Alarms are normally supplied configured as non-latching and de-energised-in-alarm, butthey can be configured as latching, energised-in-alarm, or blocking-type alarms (whichonly become active after the alarm has first entered a safe state). Up to four alarms can becombined onto a single output.

Installation and Operation Handbook Safety and EMC Information

2216e Controller B-1

Appendix B

SAFETY and EMC INFORMATION

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

This controller complies with the European Low Voltage Directive 73/23/EEC, amended by93/68/EEC, by the application of the safety standard EN 61010.

Electromagnetic compatibility

This controller conforms with the essential protection requirements of the EMC Directive89/336/EEC, amended by 93/68/EEC, by the application of a Technical Construction File. Thisinstrument satisfies the general requirements of the industrial environment defined in EN50081-2 and EN 50082-2. For more information on product compliance refer to the TechnicalConstruction File.

GENERAL

The information contained in this manual is subject to change without notice. While everyeffort has been made to ensure the accuracy of the information, Eurotherm Controls shall notbe held liable for errors contained herein.

Unpacking and storage

The packaging should contain an instrument mounted in its sleeve, two mounting brackets forpanel installation and this operating book. Certain ranges are supplied with an input adapter.If on receipt, the packaging or the instrument are damaged, do not install the product butcontact your nearest Eurotherm Controls agent. 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 nearest Eurotherm Controls agentfor repair.

Caution: Charged capacitors

Before removing an instrument from its sleeve, disconnect the supply and wait at least twominutes to allow capacitors to discharge. It may be convenient to partially withdraw theinstrument from the sleeve, then pause before completing the removal. In any case, avoidtouching 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 orsome discomfort to the user.

Safety and EMC Information Installation and Operation Handbook

B-2 2216e Controller

Electrostatic discharge precautions

When the controller is removed from its sleeve, some of the exposed electronic componentsare vulnerable to damage by electrostatic discharge from someone handling the controller. Toavoid 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 cleanother exterior surfaces of the product.

INSTALLATION SAFETY REQUIREMENTS

Safety Symbols

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

Caution, (refer to the accompanying documents)

Functional earth (ground) terminal!

The functional earth connection is not required for safety purposes but is used to ground RFIfilters.

Personnel

Installation must only be carried out by qualified personnel.

Enclosure of live parts

To prevent hands or metal tools touching parts that may be electrically live, the controller mustbe installed in an enclosure.

Caution: Live sensors

The logic and PDSIO® outputs are electrically connected to the main PV input, (thermocoupleetc.). If the temperature sensor is connected directly to an electrical heating element then thesenon-isolated inputs and outputs will also be live. The controller is designed to operate underthese conditions. However you must ensure that this will not damage other equipmentconnected to these inputs and outputs and that service personnel do not touch connections tothese I/O while they are live. With a live sensor, all cables, connectors and switches forconnecting the sensor and non-isolated inputs and outputs must be mains rated.

Wiring



It is important to connect the controller in accordance with the wiring data given in thishandbook. Take particular care not to connect AC supplies to the low voltage sensor input orother low level inputs and outputs. Only use copper conductors for connections, (exceptthermocouple). Ensure that the wiring of installations comply with all local wiring regulations.For example in the 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 that disconnects allcurrent carrying conductors. The device should be mounted in close proximity to thecontroller, within easy reach of the operator and marked as the disconnecting device for theinstrument.

Earth leakage current

Due to RFI Filtering there is an earth leakage current of less than 0.5mA. This may affect thedesign of an installation of multiple controllers protected by Residual Current Device, (RCD)or Ground Fault Detector, (GFD) type circuit breakers.

Overcurrent protection

To protect the internal PCB tracking within the controller against excess currents, the ACpower supply to the controller and power outputs must be wired through the fuse or circuitbreaker specified in the technical specification.

Voltage rating

The maximum continuous voltage applied between any connection to ground must not exceed264Vac.

The controller should 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 theproduct would not be safe.

Voltage transients across the power supply connections, and between the power supply andground, must not exceed 2.5kV. Where occasional voltage transients over 2.5kV are expectedor measured, the power installation to both the instrument supply and load circuits shouldinclude a transient limiting device.

These units will typically include gas discharge tubes and metal oxide varistors that limit andcontrol voltage transients on the supply line due to lightning strikes or inductive loadswitching. Devices are available in a range of energy ratings and should be selected to suitconditions at the installation.



Conductive pollution

Electrically conductive pollution must be excluded from the cabinet in which the controller ismounted. For example, carbon dust is a form of electrically conductive pollution. To secure asuitable 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.

Grounding of the temperature sensor shield

In some installations it is common practice to replace the temperature sensor while thecontroller is still powered up. Under these conditions, as additional protection against electricshock, we recommend that the shield of the temperature sensor is grounded. Do not rely ongrounding 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 ofthe system should fail. In temperature control applications the primary danger is that theheating will remain constantly on. Apart from spoiling the product, this could damage anyprocess 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-temperatureprotection 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 failureconditions.

INSTALLATION REQUIREMENTS FOR EMC

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

• For general guidance refer to Eurotherm Controls EMC Installation Guide, HA025464.

• When using relay or triac outputs it may be necessary to fit a filter suitable for suppressingthe conducted emissions. The filter requirements will depend on the type of load. Fortypical 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 standardis required. In this case to meet the conducted emissions requirement, a suitable mainsfilter 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 sensorinput wiring should be routed away from high-current power cables. Where it is impractical todo this, use shielded cables with the shield grounded at both ends. In general keep cablelengths to a minimum.

MOTORISED VALVE CONTROL

The 2216e can be configured for motorised valve control as an alternative to the standard PIDcontrol algorithm. This algorithm is designed specifically for positioning motorised valves.

The motorised valve algorithm operates in the Velocity mode, which does not require aposition feedback potentiometer for control purposes.

The following parameter list will appear in the navigation diagram shown in Chapter 2; if yourcontroller is configured for motorised valve control.

Table D-1 Motorised valve parameter list

COMMISSIONING THE MOTORISED VALVE CONTROLLER

Proceed as follows:

1. Measure the time taken for the valve to be raised from its fully closed to its fully openposition and enter this as the value in seconds into the ‘’ parameter.

2. Set all the other parameters to the default values shown in Table D-1.

The controller can then be tuned using the automatic or manual tuning techniques.

ADJUSTING THE MINIMUM ON-TIME ‘

The default value of 0.2 seconds is satisfactory for most processes. The minimum on timedetermines how accurately the valve can be positioned. The shorter the time, the more precisethe control. However, if the time is set too short, process noise will cause anexcessively busy valve.

Installation and Operation Handbook Load Current Monitoring and Diagnostics

2216e Controller E-1

Appendix E LOAD CURRENT MONITORING ANDDIAGNOSTICS

Current flowing in a system of electrical heating elements (the ‘Load’) can be displayed onthe controller by using a Eurotherm TE10 SSR fitted with intelligent current transformer,PDCTX, or an SSR or contactor with an external PDCTX.Load current monitoring and diagnostics may be used with any time proportioned output,fitted in module position 1A, and uses the logic output wires which drive the SSR to returnsignals back to the controller These signals represent the RMS value of the load currentduring the ON period, or load related alarm conditions. It is not designed for analogueoutputs i.e. phase angle control.It is also designed for single phase operation only.There are two modes of operation:-

1. Mode 1Detects if there is a break in the heater circuit. This includes heater or SSR open circuit.A single Load Failure alarm message is displayed on the lower readout of the controller.

2. Mode 2Provides the following:-

Display of true RMS load current Onthe lower readout of the controller

Displays the true RMS current in the ONstate to the load.

Low current alarm Analogous to PartialLoad Failure (PLF) supplied in someEurotherm SSRs

Provides advanced warning of failure ofone or more heaters in parallel

High current alarm Activated when theheater exceeds a set limit

Typically used where element bunchingmay occur

SSR short circuit This will apply full power to the heaterswhich could result in an over temperaturecondition. This alarm provides earlywarning.

THE SCALING FACTOR

The value of the current displayed on the controller is scaled using the scaling factor. Thisis found in the O.6 /. list. It is set, by default, to 100 and assumes a single turnthrough the current transformer. If two turns are made through the current transformer itwill be necessary to adjust the scaling factor to 50 to obtain the same reading.Under normal conditions you should not need to change the scaling factor.If, however, you wish to change the sensitivity of the current reading, for example, to readvery low currents you may need to change the number of turns through the PDCTX and/oradjust the scaling factor to compensate. See also note 1 below.

WHAT IS RETRANSMISSION

The controller can be configured to generate an analogue output signal which represents aselected parameter.The parameters which can be configured for retransmission are:-

1. Process Variable2. Setpoint3. Error4. Control Output

The retransmission signal is available as 0-20mA, 4-20mA, 0-5V, 1-5V or 0-10V and isconnected to terminals 1A and 1B when module 1A is fitted as a DC module.

To reverse theoutput, set 96D) toD and 96D# toD.

SCALING RETRANSMITTED OUTPUT SIGNALS

The analogue output signal may be set between 0 and 20mA. A 4-20mA output is achievedby applying an offset as described below.A 0 to 10Vdc output may be achieved by fitting a 500 ohm resistor across the outputterminals 1A and 1B. A 0 to 5Vdc output may be achieved by fitting a 250 ohm resistoracross the output terminals 1A and 1B. Suitable resistors are supplied with the controller.

5.!D# is the high limit of the input range

These are found in the O0 /. list asdescribed in Chapter 5. If the range limits are notset the retransmitted output is the maximum inputrange as stated in the order code, Appendix A.

The retransmitted output value is dependent uponthe range limits 5.!D# and 5.!D) set in the O0/. list of the controller.

The following examples are given to illustrate theretransmitted error values:

Example 1:Type K thermocouple,5.!D) = -2005.!D# = +200Retransmitted Value0mA for an error of -20010mA for an error of 020mA for an error of +200Example 2:
