Installation and Operation Handbook Installation ELECTRICAL INSTALLATION This section consists of five topics: • Rear terminal layouts • Fixed connections • Plug-in module connections • Typical wiring diagrams • Motorised valve connections. WARNING You must 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.
Installation Installation and Operation Handbook All electrical connections are made to the screw terminals at the rear of the controller. If you wish to use crimp connectors, the correct size is AMP part number 349262-1. They accept wire sizes from 0.5 to 1.5 mm2 (16 to 22 AWG). The terminals are protected by a clear plastic hinged cover to prevent hands, or metal, making accidental contact with live wires. Rear terminal layouts The rear terminal layouts are shown in Figures 1-5 and 1-6.

Installation Installation and Operation Handbook MOTORISED VALVE CONNECTIONS Motorised valves will normally be wired either to dual relay, or dual triac, output modules installed in the Module 1 position, or to single channel relay and triac outputs installed in Module positions 1 and 2. In the latter case, the convention is to configure output 1 as the raise output and output 2 as the lower output. Depending on the configuration, control of the valve is achieved in one of three ways: 1.

Operation Installation and Operation Handbook BASIC OPERATION Switch on the power to the controller. It runs through a self-test sequence for about three seconds and then shows the measured temperature, or process value, in the upper readout and the target value, called the setpoint, in the lower readout. This is called the Home display.
Operation Installation and Operation Handbook OPERATING MODES The controller has two basic modes of operation: • Automatic mode in which the output is automatically adjusted to maintain the temperature or process value at the setpoint. • Manual mode in which you can adjust the output independently of the setpoint. You toggle between the modes by pressing the AUTO/MAN button. The displays which appear in each of these modes are explained in this chapter.
Operation Installation and Operation Handbook AUTOMATIC MODE You will normally work with the controller in automatic mode. If the MAN light is on, press the AUTO/MAN button to select automatic mode. The AUTO light comes on. Power on The Home display Check that the AUTO light is on. The upper readout shows the measured temperature. The lower readout shows the setpoint. To adjust the setpoint up or down, press or .

The Home display Power on Check that the MAN light is on. The upper readout shows the measured temperature, or process value. The lower readout shows the % output. To adjust the output, press or . (Note: If Output Rate Limit has been enabled, then the lower readout will show the working output.
Operation Installation and Operation Handbook PARAMETERS AND HOW TO ACCESS THEM Parameters are settings, within the controller, that determine how the controller will operate. For example, alarm setpoints are parameters that set the points at which alarms will occur. For ease of access, the parameters are arranged in lists as shown in the navigation diagram on Pages 2-10 and 2-11.
Operation Installation and Operation Handbook Parameter names In the navigation diagram, each box shows the display for a selected parameter. The Operator parameter tables, later in this chapter, list all the parameter names and their meanings. The navigation diagram shows all the parameters that can, potentially, be present in the controller. In practice, a limited number of them appear, as a result of the particular configuration.

Installation and Operation Handbook Access Levels Chapter 3 ACCESS LEVELS This chapter describes the different levels of access to the operating parameters within the controller. There are three topics: • THE DIFFERENT ACCESS LEVELS • SELECTING AN ACCESS LEVEL • EDIT LEVEL THE DIFFERENT ACCESS LEVELS There are four access levels: • Operator level, which you will normally use to operate the controller. • Full level, which is used to commission the controller.
Access Levels Installation and Operation Handbook SELECTING AN ACCESS LEVEL Access to Full, Edit or Configuration levels is protected by a password to prevent unauthorised access. If you need to change the password, see Chapter 6, Configuration. Access list header Press until you reach the access list header ‘ACCS’. Press Password entry The password is entered from the ‘codE’ display. Enter the password using or .
Installation and Operation Handbook Access Levels Level selection The ‘Goto’ display allows you to select the required access level. Use and to select from the following display codes: OPEr: Operator level FuLL: Full level Edit: Edit level conF: Configuration level Press If you selected either ‘OPEr’, ‘FuLL’ or ‘Edit’ level you will be returned to the ‘ACCS’ list header in the level that you chose. If you selected ‘conF’, you will get a display showing ‘ConF’ in the upper readout (see below).
Access Levels Installation and Operation Handbook EDIT LEVEL Edit level is used to set which parameters you can view 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.
Installation and Operation Handbook Tuning Chapter 4 TUNING Before tuning, please read Chapter 2, Operation, to learn how to select and change a parameter. This chapter has five topics: • • • • • WHAT IS TUNING? AUTOMATIC TUNING MANUAL TUNING COMMISSIONING OF MOTORISED VALVE CONTROLLERS GAIN SCHEDULING WHAT IS TUNING? In tuning, you match the characteristics of the controller to those of the process being controlled in order to obtain good control.
Tuning Installation and Operation Handbook AUTOMATIC TUNING Two automatic tuning methods are provided in the 2408 and 2404: • A one-shot tuner, which automatically sets up the initial values of the parameters listed in Table 4-1 on the previous page. • Adaptive tuning, which continuously monitors the error from setpoint and modifies the PID values, if necessary. One-shot Tuning The ‘one-shot’ tuner works by switching the output on and off to induce an oscillation in the measured value.
Installation and Operation Handbook Tuning Typical automatic tuning cycle Temperature Setpoint Time Calculation of the cutback values Low cutback and High cutback are values that restrict the amount of overshoot, or undershoot, that occurs during large step changes in temperature (for example, under start-up conditions). If either low cutback, or high cutback, is set to ‘Auto’ the values are fixed at three times the proportional band, and are not changed during automatic tuning.
Tuning 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.
Installation and Operation Handbook 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.
Tuning Installation and Operation Handbook Integral 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.
Installation and Operation Handbook Tuning MOTORISED VALVE CONTROL The 2408 and 2404 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.
Tuning Installation and Operation Handbook COMMISSIONING THE MOTORISED VALVE CONTROLLER The commissioning procedure is the same for both bounded and boundless control modes, except in bounded mode you must first calibrate the position feedback potentiometer, as described in the section below. 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 ‘tm’ parameter. 2.
Installation and Operation Handbook Tuning 5. Press or to turn ‘PCAL’ to ‘on’. 6. Press and the upper readout indicates ‘Pot’. 7. Press or to get to ‘Pot-3A.Hi’. (Assuming that the Potentiometer Input Module is in module position 3.) 8. Press to go to ‘GO-no’. 9. Press or to see ‘GO-YES’, which starts the calibration procedure. 10. Calibration is complete when the display returns to ‘GO-no’. 11. Press and together to return directly to the Operator level. 12. The controller should still be in Manual mode.
Tuning Installation and Operation Handbook GAIN SCHEDULING Gain scheduling is the automatic transfer of control between one set of PID values and another. In the case of the 2408 and 2404 controllers, this is done at a presettable process value. It is used for the more difficult to control processes which exhibit large changes in their response time or sensitivity at, for example, high and low temperatures, or when heating or cooling. The 2408 and 2404 has two sets of PID values.
Installation and Operation Handbook Programmer Operation Chapter 5 PROGRAMMER OPERATION This chapter deals with the setpoint programming option. All 2408 / 2404 instruments have a basic 8-segment programmer built-in as standard. This facility must be enabled by the user, as explained in the section, Configuring the Programmer. Other programmer versions are listed below, and have 16-segments in each program.
Programmer Operation Installation and Operation Handbook WHAT IS SETPOINT PROGRAMMING? Many applications need to vary temperature, or process value, with time. Such applications need a controller which varies a setpoint as a function of time; all 2408 and 2404 models can do this. The setpoint is varied by using a setpoint program.
Installation and Operation Handbook Programmer Operation There are five different types of segment: Ramp The setpoint ramps linearly, from its current value to a new value, either at a set rate (called ramp-rate programming), or in a set time (called time-to-target programming). You must specify the ramp rate or the ramp time, and the target setpoint, when creating or modifying a program. Dwell The setpoint remains constant for a specified period.
Programmer Operation Installation and Operation Handbook PROGRAMMER STATES The programs have five states: Reset, Run, Hold, Holdback and End. State Description Indication Reset In Reset, the programmer is inactive and the controller behaves as a standard controller, with the setpoint determined by the value set in the lower readout. Both the RUN and HOLD lights are OFF Run In Run, the programmer varies the setpoint according to the active program.
Installation and Operation Handbook Programmer Operation RUNNING A PROGRAM FROM THE RUN LIST The Run List From the Home display, press header. until you reach the ‘run’ list Press Program number This display only appears on programmers that can store more than one program. Use or to select the required program number, from 1 to 4, or 1 to 20, depending on the particular controller. Alternatively, the program number can be selected remotely, using digital inputs on the rear terminals.
Programmer Operation Installation and Operation Handbook RUNNING A PROGRAM USING THE RUN/HOLD BUTTON If you are using a 4, or 20, program version of the controller, you must first select the number of the program that you want to run. Do this in the ‘run’ list − see the previous topic, Running a program from the Run list.
Installation and Operation Handbook Programmer Operation ‘Lo’ − Deviation Low Holdback holds the program back when the process variable deviates below the setpoint by more than the holdback value. ‘Hi’ − Deviation High Holdback holds the program back when the process variable deviates above the setpoint by more than the holdback value. ‘bAnd’ − Deviation Band Holdback is a combination of the two.
Programmer Operation Installation and Operation Handbook CONFIGURING THE PROGRAMMER When first installing a programmer you should check that the configuration conforms to your requirement. Configuration defines: • the number of stored programs (multi-programmer only) • the holdback strategy • the power fail strategy • the servo type • if event outputs are available (not 8-segment programmer) • if program synchronisation is available.
Installation and Operation Handbook Programmer Operation Power fail strategy Use or • cont: • rmP.b: • rSEt: to select Continue from last setpoint Ramp from PV to setpoint at last ramp rate Reset the program. Press Servo type Use or • to.PV: • to.
Programmer Operation Installation and Operation Handbook CONFIGURING DIGITAL INPUTS TO SELECT PROGRAM NUMBER The program number can be selected by external BCD inputs from, for example, a thumbwheel switch. The appropriate number of digital inputs must be installed in the controller and be configured for this function - see Chapter 6, Configuration. To invoke this mode of operation, the parameter ‘bcd’ in ‘inst-Conf’ must be set to ‘PrOg’. Press bcd PrOG 5-10 Use the until you reach ‘bcd’.
Installation and Operation Handbook Programmer Operation CREATING A NEW PROGRAM, OR MODIFYING AN EXISTING ONE The only difference between creating a new program, and modifying an existing one, is that a new program starts with all its segments set to End in the tYPE parameter. The procedure for both consists of setting up the parameters in the PrOG list of the Operator Navigation Diagram shown in Chapter 2.
