The controller normally operates in this mode. Manual mode - in which the output is manually adjusted by the Operator. In this mode the `MAN' light will be on. One other mode is available: Remote setpoint - The setpoint is generated as an input signal from a master 2000 series controller. In this mode the REM light is on. 1.4.1 Selecting Auto/Manual Operation 2 sec. 20.0 140.0 23.0 o C 1st press 2nd press OP 100.0 Output Actual output level % 3rd press m-A mAn Manual/Auto or Auto Man Keep pressing to return to "HOME" display to select automatic mode manual mode Figure 1.9 Auto/Manual select 2208e and 2204e Controller 1-7 Operation 1.4.2 Installation and Operation Handbook How To Manually Adjust Output Power OP1 OP2 20.0 50.0 MAN Press and hold to decrease power Actual Temperature (Process Value) Output Power Demand Manual Indicator on Press and hold to increase power Figure 1.10 The "Home Display" in manual mode Manual mode is generally used for test and commissioning purposes, take care not to leave the controller in this mode since damage or personal injury could occur. 1.5 SUMMARY To step through list headers press the Page button until the required header is obtained To step through parameters within a particular list press the Scroll button parameter is obtained To change the value (or state) of a parameter press the Raise button until the required or the Lower button The remainder of this chapter provides a complete list of all parameters available. 1-8 2208e and 2204e Controller Installation and Operation Handbook 1.6 Operation SELECTING SETPOINT 1 OR SETPOINT 2 The instrument has the facility to select two setpoints. This may be useful, for example, where it is required to switch control between two different setpoints or to control in a standby condition, thus avoiding the necessity to change the setpoint manually each time. To Select Setpoint 1 or Setpoint 2 This may be done in two ways:1. By an external switch or relay contact wired to a digital input 2. Through the front panel using the SP list 20.0 140.0 Press to select SP list Setpoint List SP LiSt Press scroll button to SSEL When setpoint 2 is selected the SP2 beacon illuminates. SSEL SP Press or to change between SP 1 and SP 2 Figure 1-11 To Select Setpoint 1 or 2 2208e and 2204e Controller 1-9 Operation 1.7 Installation and Operation Handbook RAMP DWELL FUNCTION The ramp dwell function is selected by turning the setpoint rate limit parameter SPrr to a value. It can be set to RUN in two ways:1. Through the front panel using the SP list 2. By an external switch or relay contact wired to a digital input configured for reset (rset). When closed the program will reset. When open the program will run. To run the program from the initial reset state, it is necessary to first close the switch then open it. The controller will then ramp from setpoint 1 to setpoint 2 at a rate set by the SPrr parameter. When the controller reaches setpoint 2 it can remain at this level for a timed period, using the dwel parameter. At the end of the dwell period the action of the controller is determined by the End Type parameter End.t. 1.7.1 To Set up a Ramp/Time Program Set setpoint 1 to the value at which to start the ramp. Set setpoint 2 to the value which you wish to ramp to. This is described in the previous section. Now press until SPrr is displayed SPrr 20.0 Press or to set the SP ramp rate in units per minute In Run mode the controller will ramp from SP 1 to SP 2 at 20.0 units per minute Press scroll button to dwEl Press or time in minutes to set the dwell dwel In Run mode the controller will dwell at SP 2 for 60 minutes 60.0 In Run mode the controller will reset at the end of the dwell time. Other choices are:- Press scroll button to End.t Press or to choose the action required at the end of the dwell time End.t rSEt HoLd StbY dwel The program will go into Hold The program will go into standby The program will dwell for an unlimited period Figure 1-12 Ramp/Dwell Program 1-10 2208e and 2204e Controller Installation and Operation Handbook 1.7.2 Operation To Run the Program From the previous view, press scroll button to ProG Press run or to choose Prog To reset the controller to start conditions, select rSEt run In Full access level the Status of the program can be read as follows:The status may be any one of the following: From the previous view, press scroll button to StAt rmp Ramping from SP1 to SP2 dwel Dwelling at SP2 End The program is complete. If End.t = rSEt, End will flash briefly before changing to OFF StAt rmp OFF The program is in the reset state A program may also be reset or run using an external switch contact if a digital input has been configured. See Configuration section. Figure 1-13 To Run the Ramp/Dwell Program 1.7.3 Power Failure During Program Run 1. During Ramp. After return of power, the working setpoint will servo to the current PV value, and the ramp continues to SP2 followed by the timed dwell. 2. During Dwell. After return of power the working setpoint will servo to PV, the ramp continues to SP2 followed by full programmed dwell. In effect this causes the program to restart. Use the Hide, Reveal and Promote features to customise the display for a programmer. See Chapter 3. 2208e and 2204e Controller 1-11 Operation 1.8 Installation and Operation Handbook Location of Parameters - Block Diagram The controller consists of a number of internal function blocks connected together to create a temperature controller. Each function block has a number of parameters found in lists to which the user has access. The block diagram shows location of these parameters within the controller.

They are normally used to switch an output (see 1.12) - usually a relay - to provide external actions to the process. Soft Alarms are indication only and do not operate an output. Events are generally defined as conditions, which occur as part of the operation of the plant. They do not require operator intervention and, therefore, do not cause an alarm message to be displayed. They can be attached to operate an output (relay) in the same way as an alarm. 1.11.1 Types of Alarm Used in the 2200 This section shows graphically the operation of different types of alarm used in the controller. The graphs show changes in PV plotted against time. Alarm Type PV Full Scale High Process Variable (PV) Deviation High Deviation Band Setpoint (SP) Deviation Low Full Scale Low Rate of Change Output State Full scale low Deviation low On On On On Deviation high Deviation band On On On Full scale high Rate of change On On On Time Figure 1-17: Alarm Types 2208e and 2204e Controller 1-21 Operation Installation and Operation Handbook Hysteresis is the difference between the point at which the alarm switches ON and the point at which it switches OFF. It is used to prevent relay chatter. Blocking Alarms only occur after the start up phase when the alarm has first entered a safe state. The alarm is only indicated the next time it is active. It is used, for example, to ignore start up conditions which are not representative of running conditions. Latching Alarms see 7.1.1. Loop Break Alarm. The control loop is considered to be open if the output demand signal increases to saturation level but the error does not reduce after a set period of time. The time period can be set manually, depending on the response time of the loop, using the parameter Lbt in the Alarm List (section 1.10.2). It is, also set automatically, following an autotune (see chapter 4), to 3 x Ti (integral time). The time period, Lbt, starts from the point at which the output demand reaches saturation. The loop break alarm L.br is displayed (as a diagnostic alarm, see section 1.12.3.) at the end of this period. 1.12 ALARM RELAY OUTPUT Alarms can operate a specific output (usually a relay). Any individual alarm can operate an individual relay or any combination of alarms can operate an individual relay. They are either supplied pre-configured in accordance with the ordering code or set up in configuration level. See Chapter 5 for further information. Alarm 1 nor Alarm 2 Alarm 3 Input fail Sensor break OR Relay output SEnS dIG inv Any combination of alarms can operate the relay. Typical alarms are shown Figure 1-18: Attaching Alarms to an Output 1-22 2208e and 2204e Controller Installation and Operation Handbook Operation 1.12.1 Setting Alarm Levels Up to 4 Alarms may be configured.

Similarly, if more than one alarm occurs the relevant mnemonics are flashed in the HOME display. The double flash will continue whilst the alarm condition is present and is not acknowledged. Press and together to acknowledge the alarm. If the alarm condition is still present when the alarm is acknowledged, it will be indicated by a single flash of the alarm mnemonic and this single flash will be repeated for as long as the alarm condition remains. When the alarm condition disappears the indication will also disappear.. If the alarm condition is no longer present when the alarm is acknowledged, the flashing message will disappear immediately on acknowledgement. If a relay has been attached to the alarm output (see Chapter 7 `Alarm Operation'), it will operate when the alarm condition occurs and remain in the operated condition until the alarm is acknowledged AND it is no longer present 1-24 2208e and 2204e Controller Installation and Operation Handbook Operation 1.12.3 DIAGNOSTIC ALARMS These indicate that a fault exists in either the controller or the connected devices.

They have a modular hardware construction which provides two control outputs, two alarm relays and one communications port. Two logic inputs are provided as standard. 2.2.1 Controller labels The labels on the sides of the controller identify the ordering code, the serial number, and the wiring connections. Appendix A, Understanding the Ordering Code explains the hardware and software configuration of your particular controller. 2.3 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 in position by holding it level and pushing both retaining clips forward. Note: If the panel retaining clips subsequently need removing, they can be unhooked from the side with either your fingers or a screwdriver. 2.3.1 Unplugging and plugging-in the controller The controller can be unplugged from its sleeve by easing the latching ears outwards and pulling it forward out of the sleeve. When plugging the controller back into its sleeve, ensure that the latching ears click into place to maintain moisture sealing protection. 2208e and 2204e Controller 2-3 Installation 2.4 Installation and Operation Handbook WIRING Please read Appendix B, Safety and EMC information before proceeding. WARNING ! Please 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 when ordered, or may need configuring now. See Chapter 5, Configuration. The wiring connections are shown in figure 2-5. Outputs 1 and 2 are factory fitted modules which can be any one of the types shown in figure 2-8. Check the ordering code on the controller side label to determine which have been fitted.

They accept wire sizes from 0.5 to 1.5 mm2 (16 to 22 AWG), and are protected by a hinged cover to prevent hands or metal making accidental contact with live wires. Rear terminals should be tightened to a torque of 0.4Nm (3.5 lb in). 2.4.2 Wiring connections The wiring connections are shown in figure 2-6.

Figure 2-8: Outputs 1 and 2 connections 2-6 2208e and 2204e Controller Installation and Operation Handbook 2.5 Installation PDS MODES PDS is a proprietary technique developed for bi-directional communication over a single pair of wires. There are several operating modes. In SSRx Load DoctorTM a logic output delivers a power demand signal to a TE10 solid state (SSR) relay and the SSR responds with a single load circuit failure message. In SSRx Enhanced Load DoctorTM a logic output delivers a power demand signal to an SSR and the SSR responds with the ON state rms load current, and two fault messages - SSR failure or heater circuit failure. 2.6 SNUBBERS The controller is supplied with `snubbers' (15nF +100) which should be wired across the relay or triac outputs when switching inductive loads such as mechanical contactors and solenoid valves. The snubbers are used to prolong contact life and to suppress interference when switching such loads. Snubbers pass 0.6mA at 110Vac and 1.2mA at 240Vac, which may be sufficient to hold in high impedance relay coils. They should not, therefore, be used in such installations. ! WARNING When a relay contact is used in an alarm circuit ensure that the current passing through the snubber when the relay contact is open does not hold in low power electrical loads and thereby interfere with the failsafe operation of the alarm circuit. 2208e and 2204e Controller 2-7 Installation 2.7 Installation and Operation Handbook Typical Heat/Cool Wiring Diagram Line Controller Fuse 2A(T) Cooling Power Fuse 1A(T) 1A 1B Neutral JA HA L HB N Circuit breaker HC Snubber Cooling solenoid valve HD B LA 2A HE LB 2B HF JF LC JA CT AA C AB 3A LA 3B HD AC B VI 3C HE V+ HF JF V- Heating power fuse (load dependent) - Solid State Relay + e.g. TE10 Heater Thermocouple Figure 2-9: Typical wiring diagram, Model 2208e Controller Safety requirements for permanently connected equipment state: * A switch or circuit breaker shall be included in the building installation * It shall be in close proximity to the equipment and within easy reach of the operator * It shall be marked as the disconnecting device for the equipment.

Returning to Operator Level To return to operator level from either `FuLL' or `Edit' level, select `OPEr' on the 'Goto' display, or turn the controller of and on. In `Edit' level the controller will automatically return to operator level if no button is pressed for 45 seconds. 2208e and 2204e Controller 3-3 Access Levels 3.3 Installation and Operation Handbook Edit level Edit level is used to set which parameters you can see and adjust in Operator level. It also gives access to the `Promote' feature which allows you to select and add (`Promote') up to twelve parameters into the Home display list, thereby giving simple access to commonly used parameters. Setting operator access to a parameter First you must select Edit level, as shown on the previous page. Once in Edit level you select a list or a parameter within a list in the same way as you would in Operator or Full level. hat is, you move from list header to list header by pressing the Page 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 code representing the parameter's availability in Operator level. When you have selected the required parameter, use the operator level. and buttons to set its availability in There are four codes: ALtr Makes a parameter alterable in Operator level Pro Promotes a parameter into the Home display list rEAd Makes a parameter or list header read-only (it can be viewed but not altered) HidE Hides a parameter or list header. For example: 2FSL ALtr 3.3.1 The parameter selected is the set point for Alarm 2 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 header is selected only two selections are available: rEAd and HidE. (It is not possible to hide the `ACCS' list which will always display the code: `LiSt'.) 3.3.2 Promoting a parameter Scroll through the lists to the required parameter and choose the `Pro' code. The parameter is then automatically added (promoted) into the Home display list (the parameter will also be accessible as normal from the standard lists. a maximum of 12 parameters can be promoted. Promoted parameters are automatically `alterable'. 3-4 2208e and 2204e Controller Installation and Operation Handbook Tuning 4. Chapter 4 TUNING Before tuning please read Chapter 1, Operation, to learn how to select and change a parameter. This chapter has three main topics: * WHAT IS TUNING? * AUTOMATIC TUNING * MANUAL TUNING 4.1 WHAT IS TUNING? In tuning you match the characteristics of the controller to that of the process being controlled in 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, thereby restoring the temperature rapidly to the setpoint value. Tuning involves calculating and setting the value of the parameters listed in Table 4-1. These parameters appear in the PiD list. Parameter Code Meaning or Function Proportional band Pb The bandwidth in display units over which the output power is proportioned between minimum and maximum. Integral time ti Determines the time taken by the controller to remove steady-state error signals. Derivative time td Determines how strongly the controller will react to the rate-of-change of the measured value. Low cutback Lcb The number of display units below setpoint at which the controller will cutback the output power in order to prevent overshoot on heat up. High Cutback Hcb The number of display units above setpoint at which the controller will increase the output power in order to prevent undershoot on cool down. Relative cool gain rEL.C Only present if cooling has been configured. Sets the cooling proportional band by dividing the Pb value by the rEL.C value. Table 4-1 Tuning parameters 2208e and 2204e Controller 4-1 Tuning 4.2 Installation and Operation Handbook AUTOMATIC TUNING This method automatically determines the value of the parameters listed in table 4-1 on the previous page. The 2208e and 2204e use a `one-shot' tuner which works by switching the output on and off to induce an oscillation in the measured value. From the amplitude and period of the oscillation, it calculates the tuning parameter values. If the process cannot tolerate full heating or cooling being applied during tuning, then the level of heating or cooling can be restricted by setting the heating and cooling power limits in the Output list. However, the measured value must oscillate to some degree for the tuner to be able to calculate values A One-shot Tune can be performed at any time but normally it is performed only once during the initial commissioning of the process. However, if the process under control subsequently becomes unstable (because its characteristics have changed), you can re-tune again for the new conditions. It is best to start tuning with the process at ambient temperature. This allows the tuner to calculate more accurately the low cutback and high cutback values that restrict the amount of overshoot or undershoot. 4.2.1 Heating and Cooling Output Cycle Times Before commencing a tuning cycle, set the values of CYC.H (heat cycle time) and CYC.C (cool cycle time) in the op (output list). These values apply if you are using a logic, relay or triac output. 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. 4.3 How to Tune 1. Set the setpoint to the value at which you will normally operate the process. 2. In the `Atun' list, select `tunE' and set it to `on' 3. Press the Page and Scroll buttons together to return to the Home display. The display will flash `tunE' to indicate that tuning is in progress. 4. The controller will induce an oscillation in the temperature by turning the heating on and then off. The first cycle will not complete until the measured value has reached the required setpoint. 5. After two cycles of oscillation the tuning will be completed and the tuner will switch itself off. 6. The controller will then calculate the tuning parameters listed in Table 4-1 and will resume normal control action. If you want `Proportional only' or `PD' or `PI' control, you should set the `ti' or `td' parameters to OFF before commencing the tuning cycle. The tuner will leave them off and will not calculate a value for them. For valve position tuning and set-up, please refer to Chapter 8. 4-2 2208e and 2204e Controller Installation and Operation Handbook 4.3.1 Tuning Typical automatic tuning cycle Temperature Setpoint Time 4.3.2 Calculation of the cutback values Low cutback and High cutback are values that restrict the amount of overshoot or undershoot that occur during large step changes in temperature (for example, under startup conditions). If either low cutback or high cutback is set to `Auto' the values will be fixed at three times the proportional band, and will not be changed during automatic tuning. 2208e and 2204e Controller 4-3 Tuning 4.4 Installation and Operation Handbook MANUAL TUNING If for any reason automatic tuning gives unsatisfactory results, you can tune the controller manually. There are a number of standard methods for manual tuning. The one described here is the Ziegler-Nichols method. With the process at its normal running temperature: 1. Set the Integral Time `ti and the Derivative Time `td' to OFF. 2. Set High Cutback and Low Cutback, `Hcb' and `Lcb', to `Auto' 3. Ignore the fact that the temperature may not settle precisely at the setpoint 4. If the temperature is stable, reduce the proportional band `Pb' so that the temperature just starts to oscillate. If the temperature is already oscillating, increase the proportional band until it just stops oscillating. Allow enough time between each adjustment for the loop to stabilise. 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 Proportional band `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 4-4 2208e and 2204e Controller Installation and Operation Handbook 4.4.1 Tuning Setting the cutback values The above procedure sets up the parameters for optimum steady state control. If unacceptable levels of overshoot or undershoot occur during start-up or for large step changes in temperature, then manually set the cutback parameters Lcb and Hcb. 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 (see the diagrams below). In example (a) increase Lcb by the overshoot value. In example (b) reduce Lcb by the undershoot value. Example (a) Temperature Overshoot Setpoint Time Example (b) Temperature Undershoot Time Where the temperature approaches setpoint from above, you can set Hcb in a similar manner. 2208e and 2204e Controller 4-5 Tuning 4.4.2 Installation and Operation Handbook Integrating action and manual reset In a full three-term controller (that is, a PID controller), the integral term `ti' automatically removes steady state errors from the setpoint. If the controller is set up to work in two-term mode (that is, PD mode), the integral term will be set to OFF. Under these conditions the measured value may not settle precisely at setpoint. When the integral term is set to OFF the parameter manual reset (code rES) appears in the PiD LisT in `FuLL' Access level. This parameter represents the value of the power output that will be delivered when the error is zero. You may set this value manually in order to remove the steady state error. 4.4.3 Automatic droop compensation (Adc) The steady state error from the setpoint, which occurs when the integral term is set to OFF, is sometimes referred to as `droop'. Adc automatically calculates the manual reset value in order to remove this droop. To use this facility, you must first allow the temperature to stabilise. Then, in the autotune parameter list, you must set Adc to `CALC'. The controller will then calculate a new value for manual reset, and switch Adc to `mAn'. Adc can be repeated as often as you require but between each adjustment you must allow time for the temperature to stabilise. 4-6 2208e and 2204e Controller Installation and Operation Handbook Configuration 5.

The basic calibration of the controller is highly stable and set for life. User calibration allows you 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. 2208e and 2204e Controller 6-1 User Calibration 6.2 Installation and Operation Handbook USER CALIBRATION ENABLE The User calibration facility must first be enabled in configuration level by setting the parameter `AdJ' in the CAL conf list to 'YES' This will make the User calibration parameters appear in Operator `FuLL' level.

A calibration offset is often used to allow the controller to compensate for sensor and other system errors. The normal procedure is to set up the system under test against a known independent reference, as follows: Set up the process to be calibrated such that the known reference displays the required value (temperature).

A two-point calibration is used to calibrate the controller at two points and apply a straight line between them. Any readings above or below the two calibration points will be an extension of this straight line. For this reason it is best 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 manner described above 3. Set the process under calibration such that the known reference exhibits the required higher Process Value (temperature) and allow to stabilize. 4.

Chapter 7 ALARM CONFIGURATION The 2200e series controllers are capable of very sophisticated alarm strategies and, although setting up of alarms has already been covered in previous chapters, this section has been included to enable operators and commissioning engineers to design their own strategies for optimum plant operation. 7.1 DEFINITION OF ALARMS AND EVENTS See also section 1.11 for further information on Alarms. 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 the machine 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 the normal 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 5-14). For the purposes of the operation of this instrument alarms and events can be considered the same. 7.1.1 Types Of Alarms The use of alarms in the 2208e and 2204e controllers is extremely versatile. Up to 4 alarms can be configured. Any combination of these 4 alarms can be attached to any one or more outputs, or any number of the available "soft" alarms can be combined to operate a single output. ! Note: In a three term controller at least one of these outputs is used to maintain the required temperature of the process. Outputs 1A and 2A Are plug in modules. Normally used for control outputs, eg. Heat and Cool, but can be used for alarm outputs. Outputs AA and 3A Are fixed relays. Normally used for alarms or events, but can be used as control outputs. 10A Output 4A (2204e 0nly) Is a plug in 10 Amp relay output. Normally used to switch heaters directly in control mode, but can be used as an alarm output. Note:- This option is not available on controllers after Jan-04 2208e and 2204e Controller 7-1 Alarm Configuration Installation and Operation Handbook There are seven process alarm types listed below. Alarm Types are found in configuration mode 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 PDS slave is higher than a set level. See also Chapter 9. Low Current The measured current returned from a PDS slave is lower than a set level. See also Chapter 9. Each alarm can be set to: Latching Alarm is indicated until acknowledged (Off, Auto, MAN) Auto Acknowledge: (Ltch Auto) If the alarm is acknowledged while the alarm condition is still present, it will cause the alarm to reset as soon as the alarm condition is removed. Manual Acknowledge: ( Ltch mAn) If the alarm is acknowledged while the alarm condition is still present, it will be ignored. A further acknowledgement is required when the alarm condition has been removed to cause the alarm to reset. Blocking Alarm occurs after it has been through a start up phase not in alarm condition. Sense Of Output Relay energised or de-energised in alarm condition. See also sections 1-12 and 7.4. Soft Alarms Indication only and do not operate an output. See also Section 1.11 for further information on alarm types. 7-2 2208e and 2204e Controller Installation and Operation Handbook 7.2 Alarm Configuration DIGITAL OUTPUT FUNCTIONS In addition there are nine "digital output functions" used as events or alarms depending upon the requirements of the process under control: Sensor Break The input is open circuit Loop Break The controller does not measure a response to an output change Load Failure Used with PDS Mode 1 load failure.

Chapter 8 8.1 Motorised Valve Control MOTORISED VALVE CONTROL PARAMETERS FOR MOTORISED VALVE CONTROL The 2208e and 2204e can be configured for motorised valve control as an alternative to the standard PID control algorithm. This algorithm is designed specifically for positioning motorised valves. The motorised valve algorithm operates in the boundless mode, which does not require a position feedback potentiometer for control purposes. The following parameter list will appear in the navigation diagram shown in Chapter 1 if your controller is configured for motorised valve control.

Auto 999.9 0.2 Table 8-1 Motorised valve parameter list 8.2 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 open position and enter this as the value in seconds into the `mtr' parameter. 2. Set all the other parameters to the default values shown in Table 8-1. The controller can then be tuned using the automatic or manual tuning techniques. 8.2.1 Adjusting the minimum on-time `Ont.H' The default value of 0.2 seconds is satisfactory for most processes. The minimum on time determines how accurately the valve can be positioned. The shorter the time, the more precise the control. However, if the time is set too short, process noise will cause an excessively busy valve. 2208e and 2204e Controller 8-1 Motorised Valve Control Installation and Operation Handbook 8.3 MOTORISED VALVE APPLICATIONS 8.3.1 Auto Tuning Before the auto tune is activated, the TD parameter must be set to a numeric value.

Chapter 9 LOAD CURRENT MONITORING AND DIAGNOSTICS 9.1 Load Current Monitoring and Diagnostics Current flowing in a system of electrical heating elements (the `Load') can be displayed on the controller by using a 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 return signals back to the controller These signals represent the RMS value of the load current during the ON period, or load related alarm conditions. It is not designed for analogue outputs i.e. phase angle control. It is also designed for single phase operation only. There are three modes of operation:1. Mode 1 This is used with TE10 SSR only. It detects 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 2 This is used with TE10 SSR plus PD/CTX intelligent current transformer, and provides:Display of true RMS load current On the lower readout of the controller Displays the true RMS current in the ON state to the load. Low current alarm Analogous to Partial Load Failure (PLF) supplied in some SSRs Provides advanced warning of failure of one or more heaters in parallel High current alarm Activated when the heater exceeds a set limit Typically used where element bunching may occur SSR short circuit This will apply full power to the heaters which could result in an over temperature condition. This alarm provides early warning. Heater failure Indicates open circuit load conditions 3. Mode 5 This mode is for use with contactors or other devices which do not use the PDS logic output from the controller as the drive signal. For example, a time proportioning logic,relay or triac output. Mode 5, therefore, requires an additional input to the controller to display the load conditions. It uses the digital input terminals for this, as shown in Figure 9-2. Mode 5 provides the same features as mode 2 with two additional alarms:Current Transformer Open Circuit An alarm is shown if the PDS connection to PDCTX or SSR become disconnected Current Transformer Short Circuit An alarm is shown if the PDS connection from PDCTX or SSR are short circuited 2208e and 2204e Controller 9-1 Load Current Monitoring Installation and Operation Handbook 1. 9.2 Example Wiring Diagram (For mode 1 & 2 operation) Hardware Required 1.

This is found in the inSt ConF list. It is set, by default, to 100 and assumes a single turn through the current transformer. If two turns are made through the current transformer it will 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 read very low currents you may need to change the number of turns through the PDCTX and/or adjust the scaling factor to compensate. See also note 1 below. 9.10.1 To adjust the scaling factor Do This Press This Is The Display You Should See button until inSt Conf is displayed Press Additional Notes inSt Conf until LC.Hi is displayed LC.Hi 100 or Press scaling factor to change the Note 1:Minimum Resolvable Current TE10 4A RMS.

Appendix B 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, amended by 93/68/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, amended by 93/68/EEC, by the application of a Technical Construction File. This instrument satisfies the general requirements of the industrial environment defined in EN 50081-2 and EN 50082-2. 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 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 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 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 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. 2208e and 2204e Controller 12-1 Safety Installation and Operation Handbook 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 RFI filters. Equipment protected throughout by DOUBLE INSULATION 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 must be installed in an enclosure. Caution: Live sensors The logic and PDS outputs are electrically connected to the main PV input, (thermocouple etc.). If the temperature sensor is connected directly to an electrical heating element then these non-isolated inputs and outputs will also be live. The controller is designed to operate under these conditions. However you must ensure that this will not damage other equipment connected to these inputs and outputs and that service personnel do not touch connections to these I/O while they are live. With a live sensor, all cables, connectors and switches for connecting 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 this handbook. 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). 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 that disconnects all current carrying conductors. The device should be mounted in close proximity to the controller, within easy reach of the operator and marked as the disconnecting device for the instrument. Earth leakage current Due to RFI Filtering there is an earth leakage current of less than 0.5mA. This may affect the design of an installation of multiple controllers protected by Residual Current Device, (RCD) or Ground Fault Detector, (GFD) type circuit breakers. 12-2 2208e and 2204e Controller Installation and Operation Handbook Safety Overcurrent protection To protect the internal PCB tracking within the controller against excess currents, the AC power supply to the controller and power outputs must be wired through the fuse or circuit breaker specified in the technical specification. Voltage rating The maximum continuous voltage applied between any connection to ground must not exceed 264Vac. 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 the product would not be safe. Voltage transients across the power supply connections, and between the power supply and ground, must not exceed 2.5kV. Where occasional voltage transients over 2.5kV are expected or measured, the power installation to both the instrument supply and load circuits should include a transient limiting device. These units will typically include gas discharge tubes and metal oxide varistors that limit and control voltage transients on the supply line due to lightning strikes or inductive load switching. Devices are available in a range of energy ratings and should be selected to suit conditions at the installation. 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, 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 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. 2208e and 2204e Controller 12-3 Safety Installation and Operation Handbook Installation requirements for EMC To ensure compliance with the European EMC directive certain installation precautions are necessary as follows: * For general guidance refer to EMC Installation Guide, HA025464. * When using relay or triac outputs it may be necessary to fit a filter suitable for suppressing the conducted emissions. The filter requirements will depend on the type of load. For typical applications we recommend Schaffner FN321 or FN612. * If the unit is used in table top equipment which is plugged into a standard power socket, then it is likely that compliance to the commercial and light industrial emissions standard is required. In this case to meet the conducted emissions requirement, a suitable mains filter should be installed. We recommend Schaffner types FN321 and FN612. Routing of wires To minimise the pick-up of electrical noise, the sensor input wiring should be routed away from highcurrent power cables. Where this is impractical, shielded cables should be used for the signal wiring. Where signal wiring is carrying (or could carry, under fault conditions) hazardous voltages*, double insulation should be used. * A full definition of `Hazardous' voltages appears under `Hazardous Live' in BS EN61010. Briefly, under normal operating conditions Hazardous voltage levels are defined as >30V RMS (42.2V peak) or >60V dc. 12-4 2208e and 2204e Controller Installation and Operation Handbook Safety Technical Specification Inputs General Thermocouple Range +100mV and 0 to 10Vdc (auto ranging) Sample rate 9Hz (110mS) Calibration accuracy 0.25% of reading, 1 LSD or 1C/F Resolution <1V for 100mV range, <0.2mV for 10Vdc range Linearisation accuracy <0.1% of reading Input filter 1.0 to 999.9secs Zero offset User adjustable over the fully display range Types Refer to Sensor inputs and display ranges table Cold junction compensation Automatic compensation typically >30 to 1 rejection of ambient temperature change (incorporates INSTANT ACCURACYTM cold junction sensing technology).

Supplement 2208 Instruments: New Short Sleeve Design MkIII This supplement applies to:2208 Controllers Manufactured from Feb-03 The month and year of manufacture are shown in the last two pairs of digits of the instrument serial number. From Feb-03 an improved design of 1/8 DIN short sleeve will be shipped with all new 2208 controllers. Details A new sealing gasket will be fitted onto the instrument bezel `A'. This gasket replaces the gasket which was moulded into the front of the sleeve of all previous instruments. The gasket previously moulded into the sleeve where it fits behind the panel is now supplied as a separate item `B'. Reasons for the Change This change is to ensure that IP65 sealing is reliably achieved and less physical effort is required to insert the instrument into the new sleeve. Recommendations 1. An instrument delivered after Feb 03 should be used with the sleeve supplied 2. If the instrument is required to replace one already in use, the existing sleeve should also be replaced 3. A new instrument can be fitted into an existing sleeve by carefully removing gasket `A' but IP65 sealing will not be maintained 4. An existing instrument can be fitted into a new sleeve but IP65 sealing will not be maintained It is, however, possible to achieve IP65 sealing for 3 and 4 above. A gasket kit is available from Eurotherm by quoting Part No SUB24/GAS2408. Then:5. 6. To fit a new instrument in an older sleeve carefully remove gasket `A'. Replace it with the thinner (1.25mm) gasket from the kit To fit an existing instrument into a new sleeve fit the thicker (1.6mm) gasket from the kit between the instrument and the sleeve The seal `B' supplied as a separate item with a new instrument, should be placed over the sleeve prior to mounting it through the panel cut out as shown below:- Panel New Instrument Sleeve seal `B' (supplied as a separate item) Instrument sleeve New gasket `A' fitted onto bezel 2208e and 2204e Controller 13-1 Supplement Installation and Operation Handbook This page is deliberately left blank. 13-2 2208e and 2204e Controller Installation and Operation Handbook RoHS 14.
