It can control process variables from a variety of sources such as temperature, pressure, flow and level. Inputs are user configurable for thermocouple and RTD probes, as well as linear process signal types such as mVDC, VDC or mADC. Multipoint scaling can compensate for non-linear signals. Output options include relays, SSR drivers, triacs or linear mV/voltage modules. These can be used for process control, alarms or retransmission of the process variable or setpoint to external devices. Transmitter Power Supply options can provide an unregulated 24V DC (22mA) auxiliary output voltage, or a 0 to 10VDC stabilised excitation for external signal transmitters. The operating voltage is either 100-240V at 50/60 Hz or 24V-48V AC/DC depending on the model purchased. Optional features include a USB interface, RS485 or Ethernet communications, profile controlling and data recording. Non-volatile memory protects against data or configuration loss during power outages. If the unit is left un-powered, a lithium battery powers the data recorder’s real-time clock for a minimum of one year. Alarm indication is standard on all instruments; up to five alarms can be defined. Alarms may be set as process high or low, deviation (active above or below controller setpoint), band (active both above and below setpoint), rate of input change, control loop or signal break types. Alarm status can be indicated by lighting an LED, changing the display backlight color or viewing the alarm status screen. These alarms can be linked to any suitable output. The USB Interface option allows uploading or downloading instrument configuration settings to/from a USB memory stick, for easy configuration of multiple instruments or transfer to/from the PC configuration software. If the Data Recorder of Profiler options are fitted, recordings and profile information can also be transferred via the memory stick. The controller can be programmed for on-off, time proportioning, or current proportioning control implementations, depending on the output modules fitted, and feature manual or automatic tuning of the PID parameters. A secondary control output is available when additional output modules are fitted. Optional analog Remote Setpoint inputs can be included. Configuration of the major settings is made easy by a Setup Wizard that runs automatically at first ever power-up or whenever option modules have been changed. Access to the full range of parameters is via a simple menu driven front panel interface, or the PC based configuration software. The Data Recorder option allows the user to make recordings of the process over time. Recordings can be transferred to a memory stick using the USB Port or downloaded using one of the communications options. The Profiler option allows the user to predefine up 255 segments, shared amongst up to 64 Setpoint Profiles. These control the setpoint level over time, increasing, decreasing or holding its value as required. When combined with the real-time clock of the Data Recorder option, the profiling capabilities are expanded to allow automatic program start at a defined time and day. 2 Installation Unpacking Installation 1. Remove the product from its packing. Retain the packing for future use, in case it is necessary to transport the instrument to a different site or to return it to the supplier for repair/testing. Installation should be only performed by technically competent personnel. It is the responsibility of the installing engineer to ensure that the configuration is safe. Local Regulations regarding electrical installation & safety must be observed (e.g. US National Electrical Code (NEC) or Canadian Electrical Code). 2. The instrument is supplied with a panel gasket and push-fit fixing strap. Concise manual(s) are supplied with the instrument, in one or more languages. Examine the delivered items for damage or defects. If any are found, contact your supplier immediately. 1 Instruments may be mounted side-by-side in a multiple installation, but instrument to panel moisture and dust sealing will be compromised. Allow a 20mm gap above, below and behind the instrument for ventilation. The cut-out width (for n instruments) is: (96n - 4) mm or (3.78n - 0.16) inches If panel sealing must be maintained, mount each instrument into an individual cut-out with 6mm or more clearance between the edges of the holes. Note: The mounting clamp tongues may engage the ratchets either on the sides or the top/bottom faces of the Instrument housing. When installing several Instruments side-by-side in one cut-out, use the ratchets on the top/bottom faces. Figure 1. Main dimensions Ensure the inside of the panel remains within the instrument operating temperature and that there is adequate airflow to prevent overheating. Do not remove the panel gasket, as this may result in inadequate clamping and sealing of the instrument to the panel. Figure 1. Main dimensions Once the instrument is installed in its mounting panel, it may be subsequently removed from its housing, if necessary, as described in the Fitting and Removing Option Modules section. Figure 1. Main dimensions Panel-Mounting Cleaning The mounting panel must be rigid and may be up to 6.0mm (0.25 inches) thick. The cut-out size is: Clean the front panel by washing with warm soapy water and dry immediately If the USB option is fitted, close the USB port cover before cleaning. 92mm x 92mm (+0.5mm / -0.0mm). Gasket Slide mounting clamp over the instrument housing Mounting Panel towards rear face of Clamp mounting panel until the tongues engage in ratchets Ratchets and instrument is clamped in Instrument Housing position. Hold instrument firmly in position (apply pressure to bezel only) Figure 2.

Tongues on each option module locate into a slots cut into the main boards, opposite each of 4. Reassemble the unit in its case. 4 Profiler Enabling 5. If the input board has to be replaced, a full recalibration must be carried out before the instrument is used. Refer to the calibration section of this manual for instructions. If you purchased a controller with the Profiler option installed, these features will be enabled during manufacture. Controllers supplied without the Profiler option installed can be upgraded in the field by purchasing a licence code number from your supplier. A unique code must be purchased to enable profiling on each controller that requires it. Replacement of boards must be carried out by a trained technician. If the Power Supply board does not match the labelling, users may apply incorrect voltage resulting in irreparable damage. Entering the Profiler Enable Code Hold down the “splash screen”. and keys during the power-up Using the or keys, enter the 16-character licence code in the displayed screen.

Data Recorder Board If installed, the Data Recorder memory and Real Time Clock (RTC) components are located on a plug-in daughter board attached to the front Display/CPU board. Press after entering the final character. To confirm if profiling is installed in your instrument, check the Controller Feature Information in Product Information mode. Servicing of the Data Recorder/RTC circuit and replacement of the lithium battery should only be carried out by a trained technician. 4 Electrical Instructions 4.A separate isolation transformer to feed only the instrumentation should be considered. The transformer can isolate the instrument from noise found on the AC power input. Installation should be only performed by technically competent personnel. It is the responsibility of the installing engineer to ensure that the configuration is safe. Local Regulations regarding electrical installation & safety must be observed (e.g. US National Electrical Code (NEC) or Canadian Electrical Code). AC Power Wiring - Neutral (for 100 to 240V AC versions) It is good practice to ensure that the AC neutral is at or near ground (earth) potential. A proper neutral will help ensure maximum performance from the instrument. Installation Considerations Wire Isolation Ignition transformers, arc welders, motor drives, mechanical contact relays and solenoids are examples of devices that generate electrical noise in typical industrial environments. The following guidelines MUST be followed to minimise their effects. Four voltage levels of input and output wiring may be used with the unit: 1. Analog input or output (for example thermocouple, RTD, VDC, mVDC or mADC) 2. Relays & Triac outputs 1. If the instrument is being installed in existing equipment, the wiring in the area should be checked to ensure that good wiring practices have been followed. 3. SSR Driver outputs 4. AC power 2.Noise-generating devices such as those listed should be mounted in a separate enclosure. If this is not possible, separate them from the instrument, by the largest distance possible. The only wires that should run together are those of the same category. 3. If possible, eliminate mechanical contact relays and replace with solid-state relays. If a mechanical relay being powered by an output of this instrument cannot be replaced, a solid-state relay can be used to isolate the instrument. If any wires need to run parallel with any other lines, maintain a minimum space of 150mm between them. If wires MUST cross each other, ensure they do so at 90 degrees to minimise interference. 5 Use of Shielded Cable All analog signals must use shielded cable. This will help eliminate electrical noise induction on the wires. Connection lead length must be kept as short as possible keeping the wires protected by the shielding. The shield should be grounded at one end only. The preferred grounding location is at the sensor, transmitter or transducer. Noise Suppression at Source Usually when good wiring practices are followed, no further noise protection is necessary. Sometimes in severe electrical environments, the amount of noise is so great that it has to be suppressed at source. Many manufacturers of relays, contactors etc supply ‘surge suppressors’ which mount on the noise source. For those devices that do not have surge suppressors supplied, Resistance-Capacitance (RC) networks and/or Metal Oxide Varistors (MOV) may be added. Figure 6. Contact noise suppression Figure 6. Contact noise suppression Sensor Placement (Thermocouple or RTD) If the temperature probe is to be subjected to corrosive or abrasive conditions, it must be protected by an appropriate thermowell. The probe must be positioned to reflect true process temperature: Inductive coils:- MOVs are recommended for transient suppression in inductive coils, connected in parallel and as close as possible to the coil. Additional protection may be provided by adding an RC network across the MOV. 1. In a liquid media - the most agitated area 2. In air - the best circulated area The placement of probes into pipe work some distance from the heating vessel leads to transport delay, which results in poor control. For a two wire RTD a wire link should be used in place of the third wire. Two wire RTDs must only be used with lead lengths less than 3 meters. Use of three wire RTDs is strongly recommended. Figure 5. Transient suppression with inductive coils Contacts:- Arcing may occur across contacts when they open and close. This results in electrical noise as well as damage to the contacts. Connecting a properly sized RC network can eliminate this arc. For circuits up to 3 amps, a combination of a 47 ohm resistor and 0.1 microfarad capacitor (1000 volts) is recommended. For circuits from 3 to 5 amps, connect two of these in parallel. 6 Thermocouple Wire Identification Chart The table below shows the wire and sheath colors used for most common thermocouple types. The format used in this table is: + Wire Sheath - Wire The different thermocouple types are identified by their wires color, and where possible, the outer insulation as well.

Re-calibrate the input before continuing normal operation. If the problem persists, return the instrument for servicing. Second Level Support If your supplier is unable to assist or cannot be contacted, check the Service Information Page (in Configuration Mode) for details of whom to contact. Third Level Support If further assistance is required, contact the nearest company from those listed on the back page of this manual. 16 7 Configuration and Use Operation Mode Base, Trend & Profile Operating Screens This is the mode used during normal operation of the instrument. It can be accessed from the Main Menu, and is the usual mode entered at power-up. The available displays are dependent upon the features and options fitted and the way in which it has been configured. The Base screen is the usual screen displayed during operation. It provides “at a glance” information about the process. The Profile Operating screen shows similar information when using profiles. Trend View is a graphical representation of recent process conditions. Its scale adjusts automatically for the best resolution for the visible data. DURING NORMAL USE, THE USER MUST NOT REMOVE THE CONTROLLER FROM ITS HOUSING OR HAVE UNRESTRICTED ACCESS TO THE REAR TERMINALS, AS THIS WOULD PROVIDE POTENTIAL CONTACT WITH HAZARDOUS LIVE PARTS. Note: Trend data is not retained at power down or if the Sample Interval is changed. Set all Configuration parameters as required before starting normal operations. It is the responsibility of the installing engineer to ensure that the configuration is safe for the intended application.

If the file or folder named already exists, data will be overwritten Using the USB Port The first recorder log file written is named 000001-1. csv and placed in the new Recorder sub-folder. Stopping/starting a recording does not create a new file, but each time the parameters being recorded are changed a new file is created (e.g. 000002-1.csv then 000003-1. csv etc). If any of these files would exceed the maximum spread sheet size of 65500 data lines, a new file is created with the last digit incremented by 1 (e.g. 000001-2.csv then 000001-3.csv). The USB Interface option allows the user to upload or download instrument settings to or from a USB memory stick. This allows easy configuration of multiple instruments by copying from one to another, or to transfer it to or from the PC configuration software. If the Data Recorder or Profiler options are fitted, recordings and profile information can also be transferred via USB memory stick. Refer to the USB Menu section for more details. Note: To speed up the disk operation, keep the number of files in these folders to a minimum USB Memory Stick Folders & Files When a USB stick is inserted, the instrument looks for, and if necessary creates the DEVICE, CONFIG, PROFILE and RECORDER folders. Files must be located in these folders in order to be used. When preparing to upload files from your PC, ensure that you save them to the correct folder on the memory stick. Do not remove the memory stick from the USB port whilst a data transfer operation is in progress. Data loss or corruption may result. DEVICE – This folder must be located in the Root of the USB memory stick CONFIG – Configuration files (*.bct) PROFILE – Profile program files (*.pfl) RECORDER – Recorder log folders/files The user is asked for a new recorder sub-folder name before transferring recorder data to USB. The instrument stores the log files (*.csv) in this folder. 35 9 The Data Recorder Option Calibration Reminder The features covered in this section are available on models fitted with the Data Recorder option. This option includes a USB Interface (refer to section 8) and a Real Time Clock (RTC) with battery backup. A “calibration due reminder” can be shown if the date is equal to or after the Calibration Reminder Date. The reminder screen persists until the key is pressed. If due, the reminder is shown at Power-up, and repeated every 24hrs until the reminder date is changed. The Calibration Reminder enable/disable and Reminder Date parameters can be set from the Input Configuration Menu. Introduction The Data Recorder option allows the user to make a recording of the process over time. Recordings can be transferred to a memory stick using the USB Port. Recordings are stored in Comma Separated format (.csv), suitable for use with spreadsheets, or for import in to other software. See the USB Memory Stick Folders & Files details (in section 8) for file information. Memory Use Bar Graph The bar-graph shown in the main Operation Mode screen can be set to show 0 to 100% of recorder memory used instead of the standard options of PID power or control deviation. The Bar Graph Format is defined in the Display Configuration Menu. A Recorder Configuration sub-menu is added to the Configuration Menu and Recorder Control can be optionally added to the Main Menu or Operation Mode. The RTC also expands the profiling capabilities (refer to section 10) and allows a “calibration due” reminder to be shown at a date specified by the user. Changes To Operation Mode The Data Recorder adds the option for a Calibration Reminder and a % memory use bar graph to the Operation Mode screen sequence. 10 The Profiler Option Profile Components The features covered in this section are only available on models fitted with the Profiler (Setpoint Programmer) option. If the instrument also has the Data Recorder option fitted, its Real Time Clock is used to expand the profiling capabilities by adding Day & Time profile start options, releasing of hold segments at a specific time of day and changing the power fail recovery option to one based on the length of time the power has been off. These features are explained below and in the Profiler Setup and Profile Control menus (refer to section 7) The General Profile Configuration settings decide how profiles can be Run, Held or Aborted. These settings apply to all profiles. Each profile has its own header information, plus 1 or more segments. Profile Header & Segment Information The profile header contains information about how the profile starts and stops, the power loss recovery action and how many times it should be repeated. Introduction Note: Profile Header information is stored to memory as the Segment creation sequence begins. No profile is created if you exit before this point. The Profiler option allows the user to store up to 255 profile segments, shared between a maximum of 64 Profiles. Each profile controls the value of the setpoint over time; increasing, decreasing or holding its value as required. If fitted, Profiler options are added to the Main Menu as well as the Operation Mode. Segments can be ramps, dwells, steps or special segments such as holds, ends or joins. Note: Segment information is stored as each segment is created, but the profile remains invalid until an end or join segment is defined. Profiler Enabling Controllers supplied without the Profiler option installed can be upgraded in the field by purchasing a licence code number from your supplier. Refer to the Field Upgrade information (Section 3) for more details. 36 Profile Starting & Standard Segments The example profiles below contain examples of the standard segment types required to make simple profiles or profile sequences. A Start Trigger is the instruction to begin the selected profile. Depending on the Run/Hold Signal parameter setting in the Profile Setup Menu, this can be from a Key-press given in the appropriate screen, a digital input signal or via a serial communications command. A timer start time should not clash with other profiles. A profile will not start if another is running. Remember that delays caused by manual holds or Auto-Hold can effect when the previous running profile will finish. Following a Start Trigger, profiles can start immediately, after a delay, or from the Timer (Timer start available on Recorder version only). PROFILE 1 PROFILE 9 Seg. 1 Target SP Step Ramp (Time/Rate) Starting Setpoint End Start Trigger Timer or Delay Figure 37. Dwell Join (Profile 1 to Profile 9) Profile Starting and Standard Segment Types Ramps, Dwells and Step Segments each have an end of segment Target Setpoint. A Dwell (sometimes called a soak) holds the last segment’s value for the specified Dwell Time. If a segment is a Ramp-Time type, the slope needed to reach the target in the defined time will change depending on the Starting Setpoint value. For a RampRate segment, the slope is defined by the segments Ramp Rate, so the time to reach the target setpoint will change instead. This is of particular significance for the first segment, since the starting value of the process may not be known. Step segments jump straight to the new target setpoint value. An End segment ends the profile sequence. If the last segment is a Join, the join target profile will start. Note: The Profile sequence will abort if the join target has been deleted. 37 Loops Segments continues onwards. More than one Loop Segment can be used in a profile, but they must not cross. A Loop Segment goes back to a specified segment in the current profile. This action is repeated for the required number of times (1 to 9999) before the profile Loop back target segment Example: Runs segments 1 to 5, then repeats segments 3 to 5 for 500 times, before continuing on to segments 7 to 9, x 500 End Loop Segment Figure 38. Loops Segments Profile Running / Holding vs. Hold Segments Continue Triggers Hold Start End Run Hold Stop Figure 39. Hold Segments Run/Hold & Hold Segments A Hold during a segment maintains the current setpoint value. Once the hold condition is stopped the Ramp or Dwell continues. Depending on the configuration, a hold can be the started & stopped by via a keypress, breaking the signal to a Run/Hold digital input, a serial comms command or by the Auto-Hold feature (see below). A Hold Segment is a pre-planned hold, programmed into the profile. It maintains the value of the previous segment. The profile does not continue until a Continue Trigger occurs. This can be via a key-press, a digital input signal or after waiting for a time of day (available on Recorder version only). Note: A running profile will also hold while Manual Control is selected. 38 The Auto-Hold Feature During a Dwell, the dwell time is increase by the time that the process is outside of the hold band in the selected direction(s). This ensures the process was at the desired level for the required amount of time. Each profile segment has individual Auto-Hold settings. If utilised, these ensure that the profile and the actual process remain synchronised. If the process does not closely match the required setpoint by remaining within the defined Hold Band, the profile can be held until it returns within bounds. During a Ramp segment, the ramp is held at the current setpoint value while the process is outside of the hold band in the selected direction(s). The time taken to complete the ramp is increased by the time taken by the Auto-Hold. The user can choose to hold the profile if the process goes beyond the Hold Band Above The Setpoint only, Below The Setpoint only or to Band (either side of the setpoint). When Auto-Hold becomes active, the profile status is shown as “Held”. Held if Auto-Hold set to Above Setpoint or Band Hold Band Dwell Segment Setpoint Process Variable Held if Auto-Hold set to Below Setpoint or Band Figure 40. Auto-Hold On A Dwell Segment Held if Auto-Hold set to Above Setpoint or Band Process Variable Hold Band Ramp Setpoint (without AutoHold) Ramp Setpoint (with Auto-Hold) Held if Auto-Hold set to Below Setpoint or Band Figure 41. Auto-Hold On A Ramp Segment 39 Profile Cycles & Repeat Sequences If there is a break in the input while a program is running, the unit will go to the Pre-Set Power Value during the break condition. Once the condition has ended it carries out the same recovery action as specified for power failure. A profile can be configured to run itself 1 to 9999 times or continuously using the Profile Cycles setting. A profile ending with Repeat Then End will run the entire sequence of profiles again from 1 to 9999 times before ending. Note: Recorder versions always use option E (Continue profile from the point it had reached when the power failed) if the Power Off Time is less than the Profile Recovery Time setting. If the power is off for more than this time, the defined Profile Recovery Method is used. Power/Signal Lost Recovery Actions If there is a power cut while a profile is running, the instrument will use the defined Profile Recovery Method once the power has been restored. PROFILE 4 PROFILE 31 Profile 4 Profile 7 Profile 31 Cycles = 1 Example: Runs profile 4 once, profile 31 three times & profile 7 once. This sequence is repeated ten times. PROFILE 7 Cycles = 1 Cycles = 3 Repeat Sequence = 10 Join (Profile 4 to Profile 31) Figure 42. Profile Cycles & Repeats Power On Power Off Run (Start-on SP) Repeat Then End (times to repeat = 10) Join (Profile 31 to Profile 7) Power Off Time Planned Profile = Control Off Controller SP Possible Recovery Methods: A B C D E Abort the profile and maintain the profile value from the time the power failed. Abort the profile and use Controller Setpoint value. Abort the profile with the Control outputs off. Restart the profile again from the beginning. Continue profile from the point it had reached when the power failed Figure 43. End, Abort and Recovery Actions 40 Profile End Actions Segment Type of the last profile will be carried out. The possible end actions are explained below. Once a running profile ends, that profiles’ Segment End Type defines action taken by the instrument. If a sequence of profiles has been completed, the End Run (Start-on SP) Last Profile SP Normal Profile End Controller SP = Control Off Controller SP Possible Profile End Actions: A At profile end, maintain the Final Setpoint value of the last segment. B At profile end, exit Profiler Mode and use the Controller Setpoint value. C At profile end, remain in Profiler Mode with the Control outputs off. Figure 44. Profile End Action Profile Abort Actions of the Profile Setup Menu, and is common to all profiles. If a running profile is forced to end early, the Profile Abort Action defines action taken by the instrument. This is set in the General Profile Configuration section The possible options are explained below. Last Profile SP Run (Start-on SP) Profile Aborted Controller SP Controller SP = Control Off Possible Profile Abort Actions: A Abort the profile and maintain the value of the setpoint at the time of the abort. B Abort the profile and exit Profiler Mode using the Controller Setpoint value. C Abort the profile and remain in Profiler Mode with the Control outputs off. Figure 45. Profile Abort Action 41 11 Manually Tuning Controllers Single Control Tuning (PID with Primary Output only) 2. Set the Setpoint to the normal operating value for the process (or to a lower value if overshoots beyond this value might cause damage). This technique balances the need to reach setpoint quickly, with the wish to limit setpoint overshoot at start-up or during process changes. It determines values for the Primary Proportional Band and the Integral and Derivative time constants that allow the PID control algorithm to give acceptable results in most applications that use a single control device. 3. Select On-Off control (i.e. set the Primary Proportional Band to zero). 4. Switch on the process. The process variable will oscillate about the setpoint. Record the Peak-to-Peak variation (P) of the first cycle (i.e. the difference between the highest value of the first overshoot and the lowest value of the first undershoot), and the time period of the oscillation (T) in minutes. See the example diagram below - Manually Tuning PID. This technique is suitable only for processes that are not harmed by large fluctuations in the process variable. 5. Calculate the PID control parameters using the formula below. P.Pb is the Primary Proportional Band, Int.T is the Integral Time Constant, and Der.T is the Derivative Time Constant. The Input Span is the difference between Scale Range Lower Limit and Scale Range Upper Limit: 1. Check that the Setpoint Upper Limit and Setpoint Lower Limit are set to safe levels for your process. Adjust if required. P x 100 Input Span Int.T = T minutes T Der.T = minutes 6 Process Variable P.Pb = Time Figure 46. Manually Tuning PID 42 Dual Control Tuning (PID with Primary and Secondary Outputs) PI Tuning (Valve, Damper & Speed Controllers) This tuning technique balances the need to reach setpoint quickly, with the wish to limit setpoint overshoot at start-up and during process changes. It determines values for the Primary Proportional Band, Secondary Proportional Band, Integral and Derivative time constants that allow the PID control algorithm to give acceptable results in most applications that use dual control (e.g. Heat & Cool). This tuning technique is used when controlling a damper, a modulating valve or motor speed controller. It determines values for the Primary Proportional Band, and Integral Time Constant. The Derivative Time Constant is normally set to OFF. This type of control (known as PI Control) minimises valve/motor wear whilst giving optimal process control. This technique is suitable only for processes that are not harmed by large fluctuations in the process variable. This technique is suitable only for processes that are not harmed by large fluctuations in the process variable. 1. Set the setpoint to the normal operating process value (or to a lower value if overshoot beyond this value is likely to cause damage). 1. Tune the controller using only the Primary Control output as described in the Single Control Tuning section above. 2. Set controller to On/Off Control mode (i.e. set Primary Proportional Band to the minimum value). 2. Set the Secondary Proportional Band to the same value as the Primary Proportional Band and monitor the operation of the controller in dual control mode. If there is a tendency to oscillate as the control passes into the Secondary Proportional Band, increase its value. If the process appears to be overdamped (slow to respond) in the region of the Secondary Proportional Band, decrease its value. 3. Set the Integral Time Constant to OFF. 4. Set the Derivative Time Constant to OFF. 5. Follow the instructions in the diagram on the following page. At each stage, allow sufficient settling time before moving on to the next stage. P.Pb is the Primary Proportional Band, Int.T is the Integral Time Constant 3. When the PID tuning values have been determined, if there is a disturbance to the process variable as control passes from one proportional band to the other, set the Overlap/Deadband parameter to a positive value to introduce some overlap. Adjust this value by trial and error until satisfactory results are obtained. 43 Process Variable START Apply Power to the load. Does the PV Time Tb Yes continuously Oscillate? No Note the time Are the interval Ta Oscillations Yes decaying to zero? Set P.Pb = 0.8% Set Int.T = Ta Note the period of the decaying No Multiply P.Pb setting by 1.5 oscillations (Tb) Multiply P.Pb setting by 1.5 Set Int.T = Tb Process Variable 2 END The controller is now tuned. Fine-tuning may be required to optimise the controllers Ta Time Table 26. Manually Tuning Valve Control 44 Fine Tuning. Note: Allow enough time for the controller and process to adjust between changes. A separate cycle time adjustment parameter is provided for the Primary and Secondary control when using time proportioning control outputs. 4. Initially add Derivative at a value between 1/4th and 1/10th of the Integral Time value. 5.Increase the Derivative Time if the process overshoots/undershoots, increase its value a little at a time, if the process becomes unstable, until the oscillation stops. Induce a load disturbance or make a setpoint change to verify that the process stabilises. If not decrease the value some more and re-test. Note: Adjusting the cycle time affects the controllers operation; a shorter cycle time gives control that is more accurate, but mechanical components such as relays will have a reduced life span. 1. Increase the width of the proportional band if the process overshoots or oscillates excessively. Note: When controlling a modulating valve, it is recommended that Derivative is set to OFF to avoid excessive valve activity. Derivative can cause process instability in these processes. 2.Decrease the width of the proportional band if the process responds slowly or fails to reach setpoint. 3. To find the optimum value for the Integral Time, decrease its value until the process becomes unstable, then increase it a little at a time, until stability has is restored. Induce a load disturbance or make a setpoint change to verify that the process stabilises. If not increase the value some more and re-test. 6. After making all other adjustments, if an offset exists between the setpoint and the process variable use the Bias (manual reset) to eliminate the error: Below setpoint - use a larger value Above setpoint - use a smaller value 12 Serial Communications Supported Protocols RS485 Device Addressing Communication with a Modbus RTU or Modbus TCP master device is possible if the appropriate communications module is fitted into Option Slot A. ASCII is no longer supported on the 4080. An RS485 Module is required for Modbus RTU. An Ethernet Module is required for Modbus TCP. The instrument must be assigned a unique device address in the range 1 to 255. This address is used to recognise Modbus Queries intended for this instrument. With the exception of globally addressed broadcast messages, the instrument ignores Modbus Queries that do not match the address that has been assigned to it. The instrument can also act as Setpoint Master over RS485 in multi-zone applications. In this mode the unit continuously sends its setpoint value using Modbus broadcast messages. The instrument will accept broadcast messages (global queries) using device address 0 no matter what device address is assigned. No response messages are returned for globally addressed Queries. For a complete description of the Modbus protocol refer to the description provided at http://www.modbus.org/ Ethernet Configuration All models also have a configuration socket for use with the PC configuration software. An RS232 to TTL lead (available from your supplier) is required in order to use this socket. For Modbus TCP communications (Modbus over Ethernet), the IP address can either be assigned by a Dynamic Host Configuration Protocol (DHCP), BootP or AutoIP server on the network, or manually assigned using the IP address allocation software tool. A front mounted USB port is available on some models; this can also be used to configure the instrument or to transfer recorder or profile files via a USB memory stick. Refer to the PC Software section of this manual for more information setting IP addresses. RS485 Configuration The supported data rates 10/100BASE-T (10 or 100 Mbps) are automatically detected. The RS485 address, bit rate and character format are configured via the front panel from the Comms Configuration menu or by using the PC Configurator software. Physical layer configuration settings possible are: Data rate: 4800, 9600, 19200, 38400, 57600 or 115200 bps Parity: None (default), Even, Odd Character format: Always 8 bits per character. Device Address: See following. 45 Link Layer A message for either a QUERY or RESPONSE is made up of an inter-message gap followed by a sequence of data characters. The inter-message gap is at least 3.5 data character times - the transmitter must not start transmission until 3 character times have elapsed since reception of the last character in a message, and must release the transmission line within 3 character times of the last character in a message. A Query (or command) is transmitted from the Modbus Master to the Modbus Slave. The slave instrument assembles the reply to the master. All of the instruments covered by this manual are slave devices, and cannot act as a Modbus Master. MODBUS SLAVE MASTER INSTRUMENT Note: Three character times is approximately 0.25ms at 115200 bps, 0.51ms at 57600 bps, 0.75ms at 38400 bps, 1.5ms at 19200 bps, 3ms at 9600 bps and 6ms at 4800bps. QUERY Data is encoded for each character as binary data, transmitted LSB first. For a QUERY the address field contains the address of the slave destination. The slave address is given together with the Function and Data fields by the Application layer. The CRC is generated from the given address, function and data characters. RESPONSE Figure 47. For a RESPONSE the address field contains the address of the responding slave. The Function and Data fields are generated by the slave application. The CRC is generated from the address, function and data characters. Modbus Link Layer The standard MODBUS RTU CRC-16 calculation employing the polynomial 216+215+22+1 is used. Inter-message gap Address 1 character Function 1 character Data n characters CRC Check 2 characters Supported Modbus Functions Modbus defines several function types. The following types are supported by this instrument: Function Code (decimal) Modbus Meaning Description 03 / 04 Read Holding/Input registers Read current binary value of specified number of parameters at given address. Up to 64 parameters can be accessed with one Query. 06 Write Single Register Writes two bytes to a specified word address. 08 Diagnostics Used for loopback test only. 16 (0x10 hex) Write Multiple Registers Writes up to 253 bytes of data to the specified address range. 23 (0x17 hex) Read/Write Multiple Registers Reads and Writes 253 bytes of data to the specified address ranges. 46 Function Descriptions In the function descriptions below, the preceding device address value is assumed, as is the correctly formed two-byte CRC value at the end of the QUERY and RESPONSE frames. The following is interpreted from the Modbus Protocol Description obtainable from http://www.modbus.org/. Refer to that document if clarification is required. Function 03 / 04 - Read Holding/Input Registers Reads current binary value of data at the specified word addresses Query Function 03 / 04 Address of 1st Word HI Number of Words LO HI LO RESPONSE Function Number of Bytes First Word 03 / 04 HI Last Word LO HI LO In the response the “Number of Bytes” indicates the number of data bytes read from the instrument. E.g. if 5 words are read, the count will be 10 (A hex). The maximum number of words that can be read is 64. If a parameter does not exist at one of the addresses read, then a value of 0000h is returned for that word. Function 06 - Write Single Register Writes two bytes to a specified word address. Query Function 06 Address of Word HI Value to Write LO HI LO RESPONSE Function 06 Address of Word HI Value to Written LO HI LO Note: The Response normally returns the same data as the Query. Function 08 - Loopback Diagnostic Test Query Function 08 Diagnostic Code HI =00 Value LO=00 HI LO RESPONSE Function 08 Sub-function HI=00 Value LO=00 HI LO Note: The Response normally returns the same data as the loopback Query. Other Diagnostic Codes are not supported. 47 Function 16 - Write Multiple Registers (0x10 Hex) Writes consecutive word (two-byte) values starting at the specified address Query Function 06 1st Write Address HI Number of Number of Words to Write Query Bytes LO HI 1st Query Byte 2nd Query Byte Last Query Byte etc LO LO RESPONSE Function 1st Word Address 10 HI Number of Words LO HI LO Note: The number of data bytes that can be written in one message is 253 bytes. Function 23 Hex - Read / Write Multiple Registers (0x17 hex) Reads and writes the requested number of consecutive words (two-bytes) starting at the specified addresses Query Function 17 1st Read Address HI LO Number of Words to Read HI 1st Write Address LO HI Values to Write Number of Words to Write LO HI 1st Word LO HI 2nd Word LO HI etc LO Last Word HI LO RESPONSE Read Data Function 1st Word Address 10 HI 1st Word HI 2nd Word LO HI etc LO Last Word HI LO Note: The number of data bytes that can be written in one message is 253 bytes. Exception Responses When a QUERY is sent that the instrument cannot interpret, an Exception RESPONSE is returned. Possible exception responses are: Exception Code Error Condition Interpretation 00 Unused None. 01 Illegal function Function number out of range. 02 Illegal Data Address Write functions: Parameter number out of range or not supported. (for write functions only). Read Functions: Start parameter does not exist or end parameter greater than 65536. 03 Illegal Data Value Attempt to write invalid data / required action not executed. The format of an exception response is: RESPONSE Function Exception Code Original Function code with its Most as detailed above Significant Bit (MSB) set. Note: In the case of multiple exception codes for a single QUERY the Exception code returned is the one corresponding to the first parameter in error. 48 13 Modbus Parameters The Modbus parameter register addresses are detailed in the tables below. The Modbus Address column shows the register address for each parameter in integer format. Other formats can be calculated from the Integer Only address. The Access column indicates if a parameter is read only (RO) or if it can also be written to (R/W). Communications writes will not be implemented if the Writing Via Serial Comms parameter in the Communications Configuration menu is set to Disabled. When working in Hexadecimal, the format calculations are: Address for Integer with 1 Decimal Place = Integer address plus 0x4000 Note: Some parameters that do not apply for a particular configuration will accept reads and writes (e.g. attempting to scale a Linear output which has not been fitted). Read only parameters will return an exception if an attempt is made to write values to them. Address for Floating Point = Integer address multiplied by 2, plus 0x8000 Data Formats Data can be read or written in three formats: Integer Only, Integer with 1 Decimal Place and Floating Point Number. Address for Floating Point = Integer address multiplied by 2, plus 32768 When working in Decimal, the format calculations are: Address for Integer with 1 Decimal Place = Integer address plus 16384

The very last segment of the profile must be one of the end type segments. Thereafter, no more segments can be added to the specified profile. To add a segment to an existing profile the insert segment command must be used. The information in this section is intended for advanced users writing their own software code. Most users will create or edit profiles using the instrument keypad, or using the the PC software (available from your supplier). Either method allows quick and easy editing of profiles. Instruction Sequence to create a profile at a specified profile position Advanced users can setup or edit profiles by writing to the Profile Configuration parameter at address 8198 (0x2006). This can only be accessed by using Modbus function code 23 (0x17). The instrument replies with a status message. If this profile number is already in use then the profile header data is overwritten but the segments associated with it are kept. When creating a new profile the steps below must be followed exactly, either to create a profile at the next available position, or at a position that you specify. 1. Determine which profile positions are being used by using the Command Code value PS (0x50, 0x53). This command will return a list of all the profile positions currently being used. Each message in the sequence includes a 2 byte Command Code that tells the instrument the purpose of the message, and therefore the meaning of the data contained in it. 2. Choose a location that is not being used and write the profile header data using the Command Code value WP (0x57, 0x50). Instruction Sequence to create a profile at the next available position The profile number is echoed back by the instrument in the Edit Response Message. 1. Create a profile by writing the profile header data using the Command Code value CP (0x43, 0x50). This starts the profile creation process by reserving a profile memory slot. The profile number is returned by the instrument in the Edit Response Message. 3. Write the first segment using the Command Code value Code WS (0x57, 0x53). This command will fill the next available segment position and link it to the profile created in step 1. 4. Write the second segment, again using Command Code WS. This fills the next available segment position and links it to the segment created in step 2. 2. Write the first segment using the Command Code value Code WS (0x57, 0x53). This command will fill the next available segment position and link it to the profile created in step 1. 3. Write the second segment, again using Command Code WS. This fills the next available segment position and links it to the segment created in step 2. 5. Continue writing segments until the profile is complete (whilst remaining within the overall limit of 255 segments for all profiles combined). Each of these segments fills the next available position and links it to the previous segment specified. 4. Continue writing segments until the profile is complete (whilst remaining within the overall limit of 255 segments for all profiles combined). Each of these segments fills the next available position and links it to the previous segment specified. 6. The very last segment of the profile must be one of the end type segments. Thereafter, no more segments can be added to the specified profile. To add a segment to an existing profile the insert segment command must be used. 86 Instruction Sequence to edit an existing Profile Header 2. Use the command RS to read the 1st segment’s data 3. Use the command RS to read the 2nd segment’s data. When a profile header is changed, the segments associated with it remain unchanged. They must be edited separately if required. 4.Repeat steps 2 and 3 until an end segment is reached. 1. Determine the number of the profile to be edited. Use the Command Code value PS (0x50, 0x53) which returns a list of all profile positions/numbers currently in use. The following rules apply when creating a profile over communications: • Profiles must always be terminated with an end segment. • Segments cannot be added after an end segment has been added. • All changes made to the selected profile are immediately saved in the instrument. 2. Write a new profile header data using the Command Code value EP (0x45, 0x50). The profile number is echoed back by the instrument in the Edit Response Message.

Creating new segments is only possible when a new profile is being created (see above for instruction for creating a profile at the next available position, or at a position that you specify). An error is returned if the correct sequence is not followed. The segment number is in relation to the profile number, e.g. to edit or insert a segment at position 3 of profile 1 the segment number will be 3, and to edit or insert a segment at position 3 of profile 6 the segment number will also be 3. The Insert Segment command is used to add segments to an existing profile (one that already has an end segment). This inserts a new segment at the position specified.

CALIBRATION IS ONLY REQUIRED FOR INSTRUMENTS IN WHICH CALIBRATION ERRORS HAVE BEEN ENCOUNTERED. REFER TO CALIBRATION CHECK BELOW. The 50mV phase MUST be calibrated before the thermocouple range. Calibration must be performed by personnel who are technically competent and authorised to do so. Table 27. Input Calibration phases DC milli-volt Calibration 50 mV Calibration Reminder DC voltage Calibration 10 V Calibration of each input type is carried out during manufacture. This can be verified from Product Information Mode. Recorder versions can provide the user with a calibration reminder if the application requires regular checks – see Input Configuration for details. DC milliamps Calibration 20 mA RTD Calibration 200 ohm Thermocouple Calibration K type source at 0ºC For most applications, re-calibration is not required during the lifetime of the instrument. 1. For optimum accuracy, power-up the instrument for 30 minutes, then toggle the power off/on to restart the instrument. Equipment Required For Checking or Calibrating The Universal Input 2.During the power-up “splash screen”, press and together until the Calibration Status screen is displayed. A suitable calibration signal source is required for each input type. To verify the accuracy of the instrument or carry out recalibration, the listed input sources are required. These must have better than ±0.05% of the reading accuracy: 3.Press to select the first calibration phase (50mV Calibration) 4. Ensure that an accurate 50mV signal has been applied to terminals 2 (+ve) and 3 (-ve), then press and to initiate the calibration. 1. DC linear inputs: 0 to 50mV, 0 to 10VDC and 0 to 20mADC. 5.During calibration the message “50mV DC Input Calibrating” will display for a few seconds. This should be followed by the “Calibration Successful” confirmation. 2. Thermocouple inputs - complete with 0ºC reference facility, appropriate thermocouple functions and compensating leads (or equivalent). 3.RTD inputs: decade resistance box with connections for three-wire input (or equivalent). 6. If the input is misconnected or an incorrect signal is applied, the calibration will be aborted and the display will show “Failed: Signal Too Small!” or “Failed: Signal Too Large!”. Calibration Check The previous calibration value will be retained. 1. Set the instrument to the required input type. 7.Press 2. Power up the instrument and connect the correct input leads. 8. Repeat this process for each input type until all the phases are calibrated. For each phase, ensure that the correct input is applied, using the correct connections. Leave powered up for at least five minutes for RTD and DC linear inputs, and at least 30 minutes for thermocouple inputs. 9. Once all calibration phases are completed, recorder versions will display the Calibration Reminder Date. If required, this can be changed to the date of your next calibration check. Ensure that Calibration Reminders are enabled in Input Configuration to receive a reminder. 3. After the appropriate delay for stabilisation, check the calibration by connecting the appropriate input source and checking a number of cardinal points. to select the next calibration phase. The observed readings should be within the tolerances stated in the Specification (see Appendix 2) Press 4. Repeat the test for all required input types. and to exit to the Main Menu Note: Calibration Mode automatically exits if there is no button activity for two minutes 103 15 Appendix 1 - Glossary of Terms Used Active Setpoint Alarm Hysteresis The term Active Setpoint is used to describe the currently selected setpoint when the instrument is in Controller Mode. Controllers can use Local Setpoint 1 and/ or the Alternative Setpoint. Only one of the setpoints can be active at any time. During Profiler Control, the setpoint value is controlled by the profiler function. An adjustable band through which the process variable must pass before the alarm will change state. This Hysteresis is only applicable to alarms based on the Process Value or Control Deviation, as illustrated below. The band is always on the “safe” side of an alarm point, e.g. a high alarm’s hysteresis band is below the high alarm value, and a low alarm’s hysteresis is above the low alarm value. Rate Of Change Alarms have a different type of hysteresis based on the length of time the rate is above the threshold. Also refer to: Actual Setpoint, Alternative Setpoint, Controller Mode, Local Setpoints, Profiler Mode, Remote Setpoint, Setpoint, and Setpoint Selection. Settings = 1 LSD to full span from the setpoint. Default value = 1 LSD. Actual Setpoint Actual Setpoint is the effective current value of the active setpoint. This will be different to the Active Setpoint’s target value if the setpoint is ramping. The actual setpoint will rise or fall at the ramp-rate set, until it reaches its target setpoint value. During Profiler Control, the Actual Setpoint value is controlled by the profiler function. Refer to the Alarm Hysteresis Operation diagram on the next page. Also refer to: Alarm Types, Loop Alarm, Alarm Operation, LSD, Minimum Duration Of Change, Process Variable, and Rate Of Change Alarm. Also refer to: Active Setpoint, Controller Mode, Profiler Mode, Setpoint, Setpoint Ramp Rate and Setpoint Selection.

Alarm Operation 106 Alarm Inhibit Settings = Enabled or Disabled.Default value = Disabled. Alarm Inhibit prevents unwanted process or deviation alarm activation at power-up or when the controller setpoint is changed. The alarm activation is inhibited until a ‘Safe’ condition is present. The alarm operates normally from that point onwards. E.g. if inhibited, a low alarm will not activate at power-up, until the process has first risen above the alarm point and then falls back below. Also refer to: Pre-Tune, Self-Tune, PID and Tuning. Automatic Reset - Refer to Integral Action Auxiliary Input Settings = Inhibit or not inhibited for each alarm. Default value = None Inhibited. Up to two secondary linear input modules can be installed in Option Slot A and B. These can be used as Remote Setpoint inputs. Signals can be mA, mV, VDC or Potentiometer. Auxiliary Input B also has a Digital Input onboard. Also refer to: Alarm Types and Alarm Operation. Alarm Types Also refer to: Alternative Setpoint, Digital Input, Linear Input, mADC, mVDC, Remote Setpoint and VDC There are four basic alarm types, Process Alarms, Control Deviation Alarms, Rate of Signal Change Alarms and Event Based Alarms. Auxiliary Input Lower Limit Process Alarms are based on the absolute value of the Process Variable. If the PV rises above a high alarm value, or falls below a low alarm value, the alarm will become active. Deviation Alarms are based on the value of the Control Deviation error. If the PV is more than the high deviation alarm value above setpoint, or more than the low deviation alarm value below setpoint, the alarm will become active. When the auxiliary input is used to provide a Remote Setpoint (RSP), this setting defines the value of the RSP when the auxiliary input signal is at its minimum value (e.g. for 4 to 20mA, the value when 4mA is applied). It may be adjusted within the range -1999 to 9999. However, the RSP value is always constrained by the setpoint upper limit and Lower Limits. Settings = -1999 to 9999 Range Lower Limit. Rate Of Signal Change Alarms are based on the rate of change of the PV. If the rate of change is greater than the alarm value for longer that the Minimum Duration time, the alarm will activate. Default Value = Scale Also refer to: Auxiliary Input, Auxiliary Input Upper Limit, Auxiliary Input Offset, Remote Setpoint, Setpoint and Setpoint Upper Limit and Setpoint Lower Limit. Event based alarms activate when the condition for that alarm type is true. These can be Signal Break, Low Memory Or Loop Alarms. Auxiliary Input Offset Also refer to: Alarm Operation, Band Alarm Value, Control Deviation, Deviation Alarm, Loop Alarm, Process High Alarm, Process Low Alarm, Process Variable, Rate Of Change Alarm, and Setpoint. Used to adjust the value of the Auxiliary Input. Positive values are added to the auxiliary input reading, negative values are subtracted. It is adjustable in the range –1999 to 9999. When the auxiliary input is used to provide a Remote Setpoint, this setting is added to (or subtracted from) the remote setpoint value, but the setpoint is still constrained by the etpoint upper and lower limits. Alternative Setpoint The instrument can have up to two setpoints. Local Setpoint 1 and/or an Alternative Setpoint. The Alternative Setpoint can be chosen from Local Setpoint 2 or a remote setpoint input from Auxiliary Input A or B if either of these are fitted. One setpoint can be chosen as the active at using the Setpoint Selection. Settings = ±input span Default Value = Off. Also refer to: Auxiliary Input, Remote Setpoint, Scale Range Upper Limit, Scale Range Lower Limit Setpoint Lower Limit and Setpoint Upper Limit. Also refer to: Auxiliary Input, Local Setpoints, Remote Setpoints; Setpoint and Setpoint Select. Auxiliary Input Type Auto Pre-Tune Defines the type and range of the linear input signal for the Auxiliary Input. It can be mADC, mVDC, VDC or potentiometer (mVDC and potentiometer are only available with the Full Auxiliary input in option slot B). This can be used as a Remote Setpoint input. When the Auto Pre-Tune is enabled, a Pre-Tune activation is attempted at every power-up (standard PreTune activation rules apply). Auto Pre-Tune is useful when the process to be controlled may vary significantly each time it is run. Auto Pre-Tune ensures that the process is tuned correctly each time the process is started. Self-Tune may also be engaged to fine-tune the controller. Also refer to: Remote Setpoint and Setpoint. 107 Auxiliary Input Upper Limit Bumpless Transfer When the auxiliary input is used to provide a Remote Setpoint (RSP), this setting defines the value of the RSP when the auxiliary input signal is at its maximum value (e.g. for 4 to 20mA, the value when 20mA is applied). It may be adjusted within the range -1999 to 9999. However, the RSP value is always constrained by the setpoint upper limit and Lower Limits. A method used to prevent sudden changes to the correcting variable, when switching between automatic PI or PID and Manual control modes. During a transition from PI or PID to Manual control, the initial Manual Power value is set to the previous automatic mode value. The operator then adjusts the value as required. During a transition from Manual control to PI or PID, the initial automatic value is set to the previous Manual mode value. The correcting variable level will gradually adjusted by the control algorithm at a rate dependant on the integral action resulting from the Integral Time Constant value. Since integral action is essential to Bumpless Transfer, this feature is not available if Integral is turned off. Settings = -1999 to 9999 Range Lower Limit. Default Value = Scale Also refer to: Auxiliary Input, Auxiliary Input Lower Limit, Auxiliary Input Offset, Remote Setpoint, Setpoint and Setpoint Upper Limit and Setpoint Lower Limit. Band Alarm Value Also refer to: Correcting Variable, Integral Action, Manual Mode, PI and PID. The amount of control deviation that is acceptable before a Band Alarm is activated. If the process variable is more than the value of this band from the actual setpoint, the alarm will be active. Cascade Control Applications with two or more capacities (such as heated jackets) are inherently difficult for a single instrument to control, due to large overshoots and unacceptable lags. The solution is to cascade two or more controllers, each with its own input, in series to form a single regulating device. The product setpoint temperature is set on the master controller. This is compared to the product temperature, and the master’s PID output (mA or VDC) is fed into the auxiliary input of the slave controller as a remote setpoint input. The RSP is scaled to suit any expected temperature. The slave loop’s natural response time should ideally be at least 5 times faster than the master. Settings = 1 LSD to full input span from the setpoint. Default value = 5 LSD’s. Also refer to: Actual Setpoint, Alarm Operation, Alarm Types, Control Deviation, Input Span, LSD and Process Variable. Bar Graphs The instrument displays a bar-graph in the base operation mode screen. These can show PID Power Output (single control = uni-directional, dual control = bi-directional), Control Deviation (bidirectional) or for Data Recorder version %Memory Used (uni-directional). Bar-graphs are uni-directional or bi-directional depending on the information to be displayed. In the example, the maximum input represents 400ºC, thus restricting the jacket temperature. At start-up the master compares the product temperature (ambient) to its setpoint (300ºC) and gives maximum output. This sets the maximum (400ºC) setpoint on the slave, which is compared to the jacket temperature (ambient) giving maximum heater output. Also refer to: Control Deviation, Data Recorder, Display Configuration, Operation Mode, Main Menu and PID Bias (Manual Reset) Used to manually bias proportional output(s) to compensate for control deviation errors due to process load variations. Bias is expressed as a percentage of output power. This parameter is not applicable if the Primary output is set to ON-OFF control. If the process variable settles below setpoint use a higher Bias value to remove the error, if the process variable settles above the setpoint use a lower Bias value. Integral action performs a similar function automatically when using PI or PID control. Lower Bias values will also help to reduce overshoot at process start up. As the jacket temperature rises, the slave’s heater output falls. The product temperature also rises at a rate dependant on the transfer lag between the jacket and product. This causes the master’s PID output to decrease, reducing the ‘jacket’ setpoint on the slave, effectively reducing the output to the heater. This continues until the system becomes balanced. Settings = 0 to 100% (-100% to +100% for dual control). Default value = 25%. Also refer to: Control Deviation, Integral Action, ON/ OFF Control, PI Control, PID, Proportional Control, Process Variable, and Setpoint. 108 When tuning a cascade system, first set the master to manual mode. Tune the slave controller using proportional control only (I & D are not normally required) then return the master to automatic PID mode before tuning the master. The result is quicker, smoother control with minimum overshoot and the ability to cope with load changes, whilst keeping the jacket temperature within acceptable tolerances. action, PID tuning terms, power limits, sensor break action, local setpoint values, setpoint ramp rates and setpoint selection).

Control Deviation Also refer to: Configuration Mode, Control Action, Control Enable, Local Setpoints, Manual Mode, PID, Power Limits, Sensor Break Pre-Set Power, Setpoint Ramping, Setpoint Selection and Tuning Control Deviation is the difference between the Process Variable value and the Actual Setpoint. The Control deviation error is equal to PV – SP. This value can be monitored using the bar-graph, and an excessive deviation warning can be given by using a deviation alarm.

Control Action The primary power output direction. Reverse action is typically used with heating applications as it increases the correcting variable as the process variable falls. A secondary output’s action is always the opposite of the primary output. Also refer to: Data Recorder and Configuration Mode Communications Write Enable Enables/disables the changing of parameter values via the Serial Communications link, if a communication option such as Modbus RTU (RS485) or Modbus TCP (Ethernet) is installed. When disabled, all communications are read-only. Settings = Reverse or Direct Default value = Reverse. Also refer to: Control Type, Correcting Variable, Direct Acting Control and Reverse Acting Control. Settings = Read Only or Read/Write. Default setting = Enabled (read/write). Control Enable/Disable The PID controller outputs can be temporarily turned off by disabling the control. All other functions continue as normal.

There are sub-menus for the Inputs, Control, Outputs, Alarms, Communications, Recorder, Clock, Display and Lock Codes. Configuration Mode is entered from the Main Menu. An unlock code is required to access this mode. Also refer to: Configuration Menu, Digital Input, Operation Mode and PID Control Type This defines if a controller has Single (unidirectional) or Dual (bidirectional) control outputs. Single outputs have a Primary output only. This can drive the PV in one direction (e.g. heat only, cool only, increase humidity etc). Dual outputs have both Primary and Secondary outputs which can force the PV to increase or decrease (e.g. heat & cool, humidify and dehumidify etc). Refer to the Configuration Menu information in the Configuration & Use section.

Recordings can be transferred to a USB memory stick or via the serial communications options. This option includes a USB Interface and a battery backed-up Real Time Clock. Correcting Variable The amount of output from a controller used to adjust the process variable value up or down, to remove any control deviation. The correcting variable is commonly referred to as the controller output power. Refer to the Data Recorder Option section of this manual for more details. Also refer to: Control Deviation, PID, Primary Power Output Limit and Process Variable Also refer to: Recorder Configuration. CPU Deadband This stands for Central Processing Unit and refers to the onboard microprocessor that controls the measurement, control, alarm and display functions of the instrument. Derivative Action - Refer to Overlap/Deadband. The Derivative Time Constant defines how the control action responds to the rate of change in the process variable. The power is decreased if the PV is rising, or increased if the PV is falling. This parameter is not available if primary control output is set to On-Off, and it is normally set to OFF in modulating value applications as it can cause premature wear due to constant small adjustments to the valve position. Current Proportioning Control Current proportioning control is used to produce the correcting variable on units with linear output(s). It provides 4 to 20mA, 0-20mA, 0 to 5V, 0 to 10V or 2 - 10V DC for proportional control, PI, PD or PID control modes. On-Off control cannot be used with linear outputs. Settings = OFF or 0 seconds to 99 minutes 59 seconds Default value = 01.15.

Custom Display Mode Deviation Alarm Value The user can copy up to 50 Configuration Menu parameters into Operation Mode using the PC software. It the Custom Display in enabled in the Display Configuration sub-menu, these screens follow the normal Operation Mode screens. In this mode these screens are not pass-code protected. Defines the amount of control deviation considered acceptable before a deviation alarm is activated. A positive value (deviation high) sets the alarm point above the current actual setpoint, a negative value (deviation low) sets the alarm point below actual setpoint. If the process variable deviates from the actual setpoint by a margin greater than this value, the deviation alarm becomes active. If an alarm is required if the control deviation is either side of the setpoint, consider using a Band alarm or a logical combination of a deviation high and deviation low alarm. Also refer to: Control Configuration, Display Configuration and Operation Mode Cycle Time For time proportioning outputs, the cycle time is used to define the time over which the controller averages the ON vs. OFF time, in order to provide the required correcting variable. Each Time-Proportioning output has its own adjustable cycle time. Shorter cycle times give better control, but at the expense of reduce life when used with electromechanical control devices (e.g. relays or solenoid valves). There are separate cycle times Settings = 1 LSD to full span from the setpoint D e fault value = 5 LSD’s. Also refer to: Actual Setpoint, Alarm Operation, Alarm Types, Band Alarm, Control Deviation, Logical Combination, Process Variable and Setpoint. 110 Digital Input Effective Setpoint An input that can be driven to one of two states (active or inactive) by and external voltage or a contact opening/closing. Digital Inputs can be used to set the instrument in to different states. Possible uses are to select Auto/Manual Mode, Active Setpoint, Control Output Enable/disable, Profile Run/Hold/Abort, Hold Segment Release and Recording Start/Stop. - Refer to Actual Setpoint. Engineering Units Also refer to: Active Setpoint, Control Enable, Data Recording, Manual Mode, Profiling and Segment Types. The Process Variable and Setpoint displays can assigned engineering units to describe the type of parameter connected to the process input. The engineering units for linear inputs can be: °C; °F; °K; bar; %; %RH; pH; psi or none. For temperature inputs (RTD or Thermocouples) they can be °C; °F or °K. Direct Acting Control Also refer to: Linear Input, Process Input, Process Variable RTD and Thermocouple Direct action is required for applications where the primary control output will be used to force the process variable down towards the setpoint. A typical application is a Chiller. When the control action is selected as direct acting, primary proportional control outputs decrease the correcting variable as the process variable reduces within the proportional band, and primary OnOff outputs turn off when the process variable is less than the setpoint. The control action of a secondary output is always the opposite of the primary output. Ethernet A networking technology for local area networks (LANs). Used to link computers and other equipment in order to control or share data and control such devices. If fitted with an Ethernet serial communications module in Option Slot A, this instrument can connect to a Modbus TCP master device over a wired Ethernet LAN.

Display Languages Also refer to: Auxiliary Input, Configuration Mode and Process Input. The instrument supports two languages. The main language is English. The alternate language is chosen at time of order, but can also be changed by downloading a new file via the PC software. Current supported languages are English, French, German, Italian, Spanish, Russian and Czech. Input Filter Time Constant This parameter is used to filter out extraneous impulses affecting the process variable value. The filtered PV is used for all PV dependent functions (display, control, alarm etc). Use this parameter with care as it will also slow the response to genuine process changes. Also refer to: Display Configuration, Operation Mode, and Main Menu. Settings = OFF or 0.1 to 100.0 seconds.Default value = 2.0 seconds. Display Resolution The maximum number of digits that can be displayed and/or the maximum number of decimal places. Numeric values (e.g. process variable, setpoints etc) are limited to no more than 5 digits. Also refer to: Process Variable. Input Range The maximum number of decimal places is selectable from 0 to 3 places, but the overall 5-digit limit means that larger values may not display the full number of decimal places. For example, values >99.999 can have no more than 2 decimal places(e.g. 100.00). This is the overall process variable input range and type as selected by the Process Input Type parameter. This range can be scaled by the Scale Range Upper & Lower Limits. Also refer to: LSD 111 Linear Output Also refer to: Input Span, Process Input, Scale Range Lower Limit and Scale Range Upper Limit.

Input Span Also refer to: Linear Input mVDC, mADC, Proportional Control, Retransmit Output and VDC The measuring and display limits, as defined by the Scale Range Lower and Scale Range Upper Limits. The trimmed span value is also used as the basis for calculations that relate to the span of the instrument (e.g. proportional bands). Limit Controller A safety protection device that will shut down a process at a preset “exceed condition”. Limit controllers work independently of the normal process controller in order to prevent possible damage to equipment or products. A fail-safe latching relay is fitted, which cannot be reset by the operator until the process has returned to a safe condition. Limit controllers are highly recommended for any process that could potentially become hazardous under fault conditions. Settings = 100 LSD’s to the full Input Range. Default value = Input Range Also refer to: Input Range, LSD, Primary Proportional Band, Scale Range Lower Limit, Scale Range Upper Limit and Secondary Proportional Band. Integral Time Constant Also refer to: Controller and Latching Relay. Integral action biases proportional control output(s) to compensate for process load variations, until the control deviation value is zero. Integral Time Constant is also known as “Automatic Reset”. Decreasing the time constant increases the Integral action. This parameter is not available if the primary output is set to On-Off. Local Setpoints Local setpoints are target values that are stored inside the controller. These are normally entered by from the front keypad, but can also be set via a serial communications link. Settings = 1 sec to 99 min 59 sec and OFF. Default value = 05:00 The instrument can have up to two setpoints. Local Setpoint 1 and/or an Alternative Setpoint. The Alternative Setpoint can be chosen from Local Setpoint 2 or a remote setpoint from an auxiliary input. One setpoint can be chosen as the active at using the Setpoint Selection. Also refer to: Control Deviation, On-Off Control, PI Control, PID, Primary Proportional Band, Secondary Proportional Band, Derivative Action, and Tuning. Latching Relay The value of the setpoints can be adjusted between the Setpoint Upper Limit and Setpoint Lower Limits. A type of relay that, once it becomes active, requires a reset signal before it will deactivate. If latching relays are required, they can be fitted externally as slaves to the internal (non-latching) relays of this instrument.

These menus can be selected from the Main Menu. The correct code must be entered to gain access. If unlimited access is required for any of the menus, its lock can be turned off by setting the value to OFF. Refer to the Lock Code View information in the Configuration & Use section. Also refer to: Alarm Operation, Alarm Types, Automatic Tuning and Manual Mode. Linear Input A mVDC, mADC or voltage signal used to represent the value of the process variable. This can be any variable that can be converted into a suitable DC linear signal. Common examples are Humitity, pressure, pH or temperature. Settings = 1 to 9999 or OFF. Default value = 10 Also refer to: Configuration Mode, Main Menu, Profiler Setup Menu, Recorder Menu, Setup Wizard, Supervisor Mode, Tuning Menu and USB Menu. Auxiliary linear inputs can also be installed, these can be used to provide a remote setpoint. Logical Combination of Alarms Also refer to: Auxiliary Input, Input Range, Linear Output, mVDC, mADC, Process Variable, Remote Setpoint and VDC. Outputs for alarms may be combined to create a Logical OR situation. Possible OR combinations are: Alarms 1 to 2; 1 to 3; 1 to 4 or 1 to 5. 112 Outputs for alarms & events may be combined to create a Logical AND situation. Possible AND combinations are: Alarm 1 & Event 1; Alarm 2 & Event 2; Alarm 3 & Event 3; Alarm 4 & Event 4; and Alarm 5 & Event 5. Any suitable output may be assigned as a logical output and can be configured for reverse action or direct action. The following table explains the concept of logical OR & AND outputs. Also refer to: Alarm Operation, Alarm Types, Output Configuration and Profile Events Table 28.

A loop alarm detects faults in the control feedback loop, by continuously monitoring process variable response to the control output(s). If one of the 5 alarms is defined to be a loop alarm, it repeatedly checks if the PID control output is at saturation. If saturation is reached (0% or 100% power for single control type, -100% or +100% for dual control type), an internal timer is started. Thereafter, if the output has not caused the process variable to be corrected by a predetermined amount ‘V’ after time ‘T’ has elapsed, the alarm becomes active. Subsequently, the alarm repeatedly checks the process variable and the PID output. When the process variable starts to change value in the correct sense or when the PID output is no longer at the limit, the alarm is deactivated. LSD The Least Significant Digit (LSD) is the smallest incremental value that can be shown at the defined display resolution. Also refer to: Display Resolution. mADC This stands for milliamp DC. It is used in reference to the linear DC milliamp input ranges and the linear DC milliamp outputs. Typically, these will be 0 to 20mA or 4 to 20mA. For PID control, the loop alarm time ‘T’ can be automatic (twice the Integral Time value) or set to a user defined value. Correct operation with the automatic loop alarm time depends upon reasonably accurate PID tuning. The user defined value is always used for On-Off control, and the timer starts as soon as an output turns on. Also refer to: Input Range, Linear Input, Linear Output,, mVDC, Process Variable and VDC Main Menu The top-level menu that allows access to operation mode as well as all other menus. These are: configuration mode, profiler setup and recorder menus, the setup wizard, supervisor mode and the tuning and USB menus. Most menus require an unlock code to gain access. The value of ‘V’ is dependent upon the input type. For Temperature inputs, V = 2°C or 3°F. For Linear inputs, V = 10 x LSD The loop alarm is automatically disabled during manual control mode and during execution of a Pre-Tune. Upon exit from manual mode or after completion of the Pre-Tune routine, the loop alarm is automatically re-enabled. Refer to the Main Menu information in the Configuration & Use section. Also refer to: Configuration Mode, Lock Codes, Operation Mode, Profiler Setup Menu, Recorder Menu, Set- 113 up Wizard, Supervisor Mode, Tuning Menu and USB Menu. retransmission is use, the slave controller must have a matching a remote setpoint input. It is possible to apply an offset to each zone if the slave has a Setpoint offset parameter or by offsetting its remote setpoint input (or adjusting the scaling of this input). Manual Loop Alarm Time The loop alarm time used when a loop alarm is defined to have a manually set time or whenever On-Off control is selected. This parameter determines the duration of the output saturation condition after which the loop alarm will be activated. Settings = 1 sec to 99 mins 59 sec. = 99:59. Cascade Control is another type of Master & Slave application where the slaves setpoint is set using the master controllers PID power output. The terms Master and Slave are also used in a different context in relation to serial communications. Default value Also refer to: Cascade Control, Linear Output, Retransmit Output, Remote Setpoint, Auxiliary Input Offset, Serial Communications and Setpoint. Also refer to: Loop Alarm, and On-Off Control. Manual Mode Minimum Duration Of Change If Manual Mode is enabled/disabled (from the control configuration sub-menu, or the Auto/manual screen in operation mode if it is available) it allows the controller to switch between automatic and manual control modes. Auto/Manual Mode can also be switched using a digital input if one has been configured for this function. Switching between automatic and manual modes is achieved using “bumpless transfer”. A form of alarm hysteresis unique to the Rate Of Change Alarm. It is the minimum time that the rate of change in the process variable must be above the alarm threshold, before the alarm will change state (from on to off, or off to on). Settings = 1 to 9999 secs. Default value = 1sec. Caution: If the duration is less than this time, the alarm will not activate no matter how fast the rate of rise. Manual Mode operates as follows: The setpoint legend is replaced by the word MAN and setpoint value is replaced by a % output power value. This value may be adjusted using the or keys. The power value can be varied from 0% to 100% for controllers using single control type, and -100% to +100% for controllers using dual control type. It is possible to use a controller as a permanent “Manual Station” by selecting Manual Control in the control configuration sub-menu. Also refer to: Alarm Hysteresis, Alarm Types and Rate Of Change Alarm. Modbus RTU Modbus RTU is the serial communications protocol used on instruments fitted with the RS485 Communications module into Option Slot A. Alternatively, the Modbus TCP protocol is available if the Ethernet Communications Module is fitted. Modbus RTU is a Master/Slave protocol. Only the Master may initiate communications. Each slave is given a unique address, and the message contains the Modbus address of the intended slave. Only this slave will act on the command, even though other devices might receive it (an exception is specific broadcast commands sent to address 0 which are acted upon by all slaves but not acknowledged). Manual Mode should be used with care because the power output level is set by the operator, therefore the PID algorithm is no longer in control of the process. The operator MUST maintain the process at the desired level manually. Manual power is not limited by the Power Output Limits. The commands can instruct the slave to change a value in one of its registers, or ask it to send back one or more values contained in its registers. The Modbus RTU format follows the messages with a cyclic redundancy check (CRC) checksum to ensure that the message arrives undamaged. Also refer to: Bumpless Transfer, Control Configuration, Control Type, Operation Mode, PID, and Power Output Limits. Master & Slave Controllers This instrument can act as a Slave or as a Setpoint Master over RS485. In this mode the unit continuously sends its setpoint value using Modbus broadcast messages. The terms master and slave are used to describe the controllers in multi-zone applications where one instrument controls the setpoint of another. These can be simple Setpoint Master/Slave applications where the master controller transmits its setpoint to the slaves via serial communications, or retransmits it as an analog DC linear output signal. If serial comms are used, the master controller must be able to act as a communications master device and the slave must have a compatible communications option fitted. If DC linear Refer to the Serial Communications and Modbus Parameter sections of this manual for more information. Also refer to: Modbus TCP, RS485 and Serial Communications. 114 Modbus TCP On-Off Control Modbus TCP is a version of the Modbus protocol for networks that support the Internet Protocol, such as Ethernet. It is available if the Ethernet Communications Module is fitted into Option Slot A. When operating in On-Off mode, the control output(s) will turn on or off as the process variable crosses the setpoint in a manner similar to a central heating thermostat. Some oscillation of the process variable is inevitable when using On-Off control. This instrument can only act as a Slave when using Modbus TCP. A master device initiates the communications, and the instrument only acts on the command if it has been sent to its IP address. The data model and function calls used by Modbus TCP and RTU are identical; only the encapsulation is different. Modbus/ TCP does not require a checksum to ensure that the message arrives intact. On-Off control can be implemented only with Relay, Triac or SSR driver outputs. On-Off operation can be assigned to the Primary output alone (secondary output not present), Primary and Secondary outputs or Secondary output only (with the primary Output set for time proportional or current proportional control). OnOff Control is selected by setting the corresponding proportional band(s) to On-Off. Refer to the Serial Communications and Modbus Parameter sections of this manual for more information. Also refer to: On-Off Differential, PID, Process Variable, Primary Proportional Band, Secondary Proportional Band, Relay, Setpoint, SSR Driver, Time Proportioning Control and Triac. Also refer to: Ethernet, Modbus RTU and Serial Communications. Modulating Valve On-Off Differential (On-Off Hysteresis) A valve that can be positioned anywhere between fully closed and fully open by means of an incorporated motor. A typical application would be controlling temperature in a furnace heated by gas burners. This instrument can control modulating valves that have a positioning circuit. These require proportional (mA or VDC) control signal from a linear output, relative to the desired valve position. PI control is used for valve control. A switching differential, centred about the setpoint, when using On-Off control. Relay ‘chatter’ can be eliminated by proper adjustment of this parameter, but too large a value may increase process variable oscillation to unacceptable levels. On-Off differential is also known as hysteresis or deadband. Settings = 0.1% to 10.0% of input span. Default value = 0.5%. To directly control the valves ‘open’ and ‘close’ motor windings, a special Valve Motor Drive (VMD) controller algorithm is required. This instrument does not currently support this type of algorithm. Also refer to: Input Span, On-Off Control, Process Variable, Relay and Setpoint Operation Mode Also refer to: Linear Output, PI Control, Proportional Control and Valve Motor Drive Control. The mode used during normal operation of the instrument. It can be accessed from the Main Menu, and is the usual mode entered at power-up. The screens shown include a main screen with bar-graph, a trend view, information about the process, alarms plus optionally, selection of auto/manual control, control output disabling. Recorder and profiler information can be displayed if these features are fitted. Up to 50 configuration menu screens can be defined with the PC software, and will be shown if the Custom Display mode is enabled in the Display Configuration sub-menu. Multi-Point Scaling If the process input is connected to a linear input signal, multi-point scaling can be enabled in the Input Configuration sub-menu. This allows the linearization of a non-linear signal. The Scale Range Upper & Lower Limits define the values shown when the input is at minimum and maximum values, and up to 15 breakpoints can scale input vs. displayed value between these limits. It is advisable to concentrate these break points in the area of the range that has the greatest amount of non-linearity, or the area of particular interest in the application.

Also refer to: Auxiliary Input, Input Range, Linear Input, mADC, Process Variable and VDC 115 Overlap/Deadband rameter has the effect of moving the On-Off Differential band of the Secondary Output to create the overlap or deadband. When Overlap/Deadband = OFF, the edge of the Secondary Output Differential band coincides with the point at which the Primary Output = 0%. The Overlap/Deadband parameter defines the portion of the primary and secondary proportional bands over which both outputs are active (called Overlap), or neither is active (called Deadband). This is adjustable in the range -20% to +20% of the sum of the two proportional bands. Positive values = Overlap, negative values = Deadband. The effect of the Overlap/Deadband parameter is shown in the following table Settings = -20% to +20%. Overlap/deadband is applicable if the primary output is set for On-Off control or there is no Secondary Output.

Proportional and Derivative (PD) control combines proportional control with derivative action. It is similar to PID control, but without Integral action. PLC This stands for Programmable Logic Controller. A microprocessor based device used in machine control. It is particularly suited to sequential control applications, and uses “Ladder Logic” programming techniques. Some PLC’s are capable of basic PID control, but tend to be expensive and often give inferior levels of control. Also refer to: Derivative, Integral, PID Control, Proportional Control and Tuning. PI Control Proportional and Integral Control (PI) is most often used for modulating valve or motor control. It combines proportional control with integral action. It is similar to PID Control, but without derivative action that can cause excessive valve movement. Also refer to: PID. Pre-Tune The Pre-Tune facility artificially disturbs the start-up pattern so that a first approximation of the PID values can be made prior to the setpoint being reached. During Pre-Tune, the controller outputs full Primary Power until the process value has moved approximately halfway to the setpoint. At that point, power is removed (or full Secondary Power is applied for Dual Control), thereby introducing an oscillation. Once the oscillation peak has passed, the Pre-Tune algorithm calculates an approximation of the optimum PID tuning terms proportional band(s), integral and derivative. The Pre-Tune process is shown in the following diagram. Also refer to: Derivative, Integral, Modulating Valve, PID Control, Proportional Control and Tuning. PID Control Proportional Integral and Derivative control maintains accurate and stable levels in a process (e.g. when controlling a temperature). Proportional Control avoids the oscillation characteristic of On-Off control by continuously adjusting the correcting variable output(s) to keep the process variable stable. Integral action eliminates control deviation errors, and Derivative action counters rapid process movements. When Pre-Tune is completed, the PID control output power is applied using the calculated values. Pre-Tune limits the possibility of setpoint overshoot when the controller is new or the application has been changed.

Pre-Tune Operation 117 Process Input Pre-Tune can be selected from the Automatic Tuning Menu. It will not engage if either primary or secondary outputs on a controller are set for On-Off control, during setpoint/profile ramping or if the process variable is less than 5% of the input span from the setpoint. As a single-shot operation, Pre-Tune will automatically disengage once complete, but can be configured to run at every power up using the Auto Pre-Tune function. The main input used to monitor the value process to be controlled. This is known as the Process Variable or PV. The input circuit is a “Universal” type, supporting all common thermocouples and PT100 RTDs as well as DC linear mV, voltage or mA signals suitable for almost any parameter that can be converted into a electronic signal. Linear signals can be scaled into engineering units using the Scale Range Lower Limit and Scale Range Upper Limit parameters. Also refer to: Auto Pre-Tune, Control Type, Derivative Action, On-Off Control, Input Span, , Integral, PID, Primary Proportional Band, Process Variable, Secondary Proportional Band, Self-Tune, Setpoint, Setpoint Ramping, and Tuning. Also refer to: Auxiliary Inputs, Engineering Units, Input Span, PV Offset, Process Variable , Scale Range Lower Limit and Scale Range Upper Limit. Power Output Limits Process Low Alarm n Value Used to limit the power levels of the primary and secondary control outputs. Normally the instrument can set these outputs to any value between 0% and 100%. If this is undesirable in a particular application, individual settings can limit the primary power upper and lower levels and the secondary power upper and lower levels. The upper limit values must be higher than the lower limits. These parameters are not applicable if that output is set for On-Off control. An independent low alarm value parameter is available for each alarm that is set as Process Low type. It defines the process variable value below which Alarm n will be active. Settings = Scale Range Upper to Lower Limit fault Value = Scale Range Lower Limit. Also refer to: Alarm Operation, Alarm Types, Process Variable, Scale Range Lower Limit and Scale Range Upper Limit. Use with caution: The instrument will not be able to control the process if the limits do not allow the outputs to be set to the correct values to maintain setpoint. Lower Limit settings = 0% and 100% = 0%. Default Value Upper Limit settings = 0% and 100% = 100%. Default Value D e - Process Variable (PV) Process Variable is the parameter that is to be controlled. It is monitored by the main process input of the instrument, and can be any type that can be measured by that circuit. Common types are Thermocouple or RTD temperature probes, or pressure, level, flow etc from transducers that convert these parameters into DC linear input signals (e.g. 4 to 20mA). Linear signals can be scaled into engineering units using the Scale Range Lower Limit and Scale Range Upper Limit parameters. Also refer to: Control Type, On-Off Control and Setpoint. Primary Proportional Band The portion of the input span over which the Primary Output power level is proportional to the process variable value. Applicable if Control Type is single or dual. For dual control a Secondary Proportional band is used for the second output. The Control Action can be Direct or Reverse acting. Also refer to: Actual Setpoint, Engineering Units, Input Span, Linear Input, Process Input, RTD, Scale Range Lower Limit, Scale Range Upper Limit and Thermocouple. Settings = On-Off Control or 0.5% to 999.9% Default Value = 10%. Process Variable Offset Also refer to: Control Action, Control Type, On-Off Control, Input Span, Overlap/Deadband, PID, Secondary Proportional Band, and Tuning. The Process variable offset is used to modify the measured process variable value. Use this parameter to compensate for errors in the displayed process variable. Positive values are added to the process variable reading, negative values are subtracted. Caution: This parameter is in effect, a calibration adjustment; it must be used with care. Injudicious use could lead to the displayed value bearing no meaningful relationship to the actual process variable. There is no front panel indication of when this parameter is in use. Process High Alarm n Value An independent high alarm value parameter is available for each alarm that is set as Process High type. It defines the process variable value above which Alarm n will be active. Settings = Scale Range Upper to Lower Limit Default Value = Scale Range Upper Limit. Settings = ±input span Default Value = Off. Also refer to: Input Span and Process Variable. Also refer to: Alarm Operation, Alarm Types, Process Variable, Scale Range Lower Limit and Scale Range Upper Limit. 118 Profile Control Menu Profiler If the Profiler option is fitted, a Profile Control menu is available from the Main Menu. It allows the user to select or run a profile, and then control that profile (run, hold, abort, skip to next segment etc.). A profiler controls the value of the actual setpoint over time; increasing, decreasing or holding its value as required. This is used in applications where the rate of rise or fall of the process variable must be closely controlled, or where a value must be maintained for a period before moving to the next value. Refer to the Profiler Control Menu information in the Configuration & Use section. If the Profiler option is fitted, up to 64 profiles can be created with a maximum of 255 profile segments shared amongst them. Each segment can activate/deactivate the five events according to the requirements of the process. Also refer to: Main Menu, Profile Setup Menu, Profiler and Profiler Mode. Profile Events Events are outputs that can be made active during profile segments. There are 5 possible events, each of which can be defined to be active or inactive for the duration of each segment, from the Profile Setup Menu. For end segments, events selected to be active stay on until the unit is powered down or a new profile runs. It is possible to link event outputs to certain alarm outputs in a logical AND situation. Refer to the Profiler Option section. Also refer to: Actual Setpoint, Controller Mode, Profile Events, Profile Control Menu, Profile Header, Profile Segments, Profile Setup Menu and Profiler Mode. Profiler Mode This mode is entered when a profile is run. In profiler mode, additional screens are added to Operation Mode which show the status of the profile. These screens are not seen in Controller Mode. The instrument will remain in Profiler Mode when the profile finishes or is aborted unless the Segment End Type/Profile Abort Action is set to “Use Controller Setpoint”. Also refer to: Alarm Types, Logical Combinations, Profile Segments, Profile Setup Menu, Profiler and Profiler Mode Profile Header The profile header contains information about how the profile starts and stops, the power loss recovery action and if the profile should repeat multiple times when run. Also refer to: Controller Mode, Profile Control Menu, Profile Segments, Profile Setup Menu, Profiler and Setpoint. Refer to the Profile Components information in the Profiler Option section of this manual. Proportional Control Also refer to: Profile Segments, Profile Setup Menu, Profiler and Profiler Mode. Proportional control allows the correcting variable applied to the process to be set between 0 and 100% of the amount available. If the control type is dual, two outputs (primary & secondary) are available, each of which can give proportional control. When the Proportional Band(s) are correctly tuned, the process variable is maintained at a steady value, avoiding the oscillation characteristic of On-Off control. Proportional control is most commonly used in conjunction with Integral and Derivative action to give PI. PD or PID control. Profile Segments Segments can be ramps, dwells, steps or special segments such as holds, ends or joins. A maximum of 255 segments are possible, shared amongst up to 64 profiles. Refer to the Profile Components information in the Profiler Option section of this manual. Also refer to: Control Type, Correcting Variable, Derivative Action, Integral Action, On-Off Control, PD, PI, PID, Primary Proportional Band, Process Variable, Secondary Proportional Band, Setpoint and Tuning. Also refer to: Profile Events, Profile Setup Menu, Profiler and Profiler Mode. Profile Setup Menu Rate If the Profiler option is fitted, a Profile Setup menu is available from the Main Menu. It allows the user to set the General Profile Configuration parameters that apply to all profiles (e.g. Run/hold and abort methods etc), and to create or edit the Profile Header and Profile Segment Details. Profiles can also be deleted from this menu. This menu is protected by a lock code. - Refer to Derivative Action. Rate of Change Alarm An alarm based on the rate of change in the measured process variable. If the PV changes at a rate greater than the alarm level, the alarm will activate. The rate of change must be above the alarm threshold for longer than the Minimum Duration of Change time, before the alarm will change state (from on to off, or off to on). Caution: If the duration is less than this time, the Refer to the Profiler Setup Menu information in the Configuration & Use section. Also refer to: Lock Codes, Profile Control Menu, Profile Header, Profile Segments, Profiler and Profiler Mode. 119 alarm will not activate no matter how fast the rate of rise. cal Setpoints, Master & Slave, mADC, mVDC, Setpoint and Setpoint Select, and VDC. Also refer to: Alarm Hysteresis, Alarm Operation, Alarm Types, Minimum Duration Of Change and Process Variable. Retransmit Output A linear VDC or mADC output signal, proportional to the Process Variable or Setpoint, for use by slave controllers or external devices, such as a Chart Recorder or PLC. The output can be scaled to transmit any portion of the input or setpoint span. Recorder Configuration If the Data Recorder is fitted, a Recorder Configuration sub-menu is added to Configuration Mode. This is used to adjust the recorder parameters (Recording mode, sample interval, trigger and values to record) and to show the recorder status. Also refer to: Configuration Mode, and Data Recorder Also refer to: Input Span, Linear Output, mADC, Master & Slave, PLC, Process Variable, Retransmit Output Scale Maximum, Retransmit Scale Minimum, Setpoint and VDC. Recorder Option Retransmit Output n Scale Maximum Scales a linear output module in slot n if it has been selected to retransmit the PV or SP. Retransmit Scale Maximum defines the value of the process variable, or setpoint, at which the output will be at its maximum value. E.g. for a 0 to 5V output, it is the PV or SP value corresponding to 5V. If this parameter is set to a value less than that for Retransmit Output n Scale Minimum, the relationship between the process variable/setpoint value and the retransmission output is reversed so that higher PV/SP values give a lower output level. - Refer to Data Recorder. Recorder Menu If the Data Recorder is fitted, a Recorder Menu is added to the Main Menu. This is used to control the recording (start, stop, delete recordings etc) and to show the recorder status. This menu is protected by a lock code. Refer to the Recorder Menu information in the Configuration & Use section. Settings = -1999 to 9999 Range Upper Limit. Also refer to: Lock Codes, Main Menu and Data Recorder Default value = Scale Also refer to: Process Variable, Retransmit Output, Retransmit Output n Scale Minimum, Scale Range Upper Limit and Setpoint. Relay An electromechanical switch operated by a solenoid coil. Relays are commonly fitted as internal, time proportioning controller outputs. The limited current capacity and switching cycles of internal relays means that they are usually connected to larger external slave relays/contactors which are capable of switching much larger currents and are easily replaced once worn out. A suitably rated RC snubber should be connected to relays to protect nearby equipment from the effects of noise generated as they switch (refer to the Noise Suppression details in the Electrical Installation section). Retransmit Output n Scale Minimum Also refer to: Current Proportioning Control, Latching Relay, SSR Driver, Time Proportioning Control and Triac Scales a linear output module in slot n if it has been selected to retransmit the PV or SP. Retransmit Scale Minimum defines the value of the process variable, or setpoint, at which the output will be at its minimum value. E.g. for a 0 to 5V output, it is the PV or SP value corresponding to 0V. If this parameter is set to a value greater than that for Retransmit n Output Scale Maximum, the relationship between the process variable/ setpoint value and the retransmission output is reversed so that higher PV/SP values give a lower output level. Remote Setpoint (RSP) Settings = -1999 to 9999 Range Lower Limit. If the alternative setpoint type is selected to be a remote setpoint, and the selected setpoint is the alternative setpoint, an Auxiliary Input value is used to adjust the controller setpoint. The auxiliary linear input, is given a VDC or mADC signal, or in some cases potentiometer or mV inputs. The Remote Setpoint value is constrained by the Setpoint Upper Limit and Setpoint Lower Limit settings. Typical applications are Setpoint and Cascade Control Slaves. Default value = Scale Also refer to: Process Variable, Retransmit Output, Retransmit Output n Scale Maximum, Scale Range Lower Limit and Setpoint. Also refer to: Alternative Setpoint, Auxiliary Input, Auxiliary Input Lower Limit, Auxiliary Input Type, Auxiliary Input Upper Limit, Cascade Control, Linear Input, Lo- 120 Reset To Defaults RTD This Configuration sub-menu selection returns all of the instruments settings back to their factory defaults. It should be used with great care, as the action cannot be undone. A reset is followed automatically by the Setup Wizard. Users must use this wizard and/or configuration menus to set all of the parameters to the correct values for the intended application. Resistance Temperature Detector. A temperature sensor that changes resistance with a change in the measured temperature. This instruments process input supports PT100 (platinum, 100Ω at 0°C) and NI120 (nickel, 120Ω at 0°C) sensors. These have positive temperature coefficients (PTC) which means their resistance increases with higher temperatures. The temperature measured by the sensor can be displayed as °C; °F or °K. Also refer to: Configuration Menu, and Setup Wizard Also refer to: Input Range, Process Input and Thermocouple. Reverse Acting Control Reverse control action is required for applications where the primary control output will be used to force the process variable up towards the setpoint. A typical application is a furnace. When the control action is selected as reverse acting, primary proportional control outputs decrease the correcting variable as the process variable increases within the proportional band, and primary On-Off outputs turn off when the process variable exceeds the setpoint. The control action of a secondary output is always the opposite of the primary output. Scale Range Upper Limit For linear inputs, this parameter is used to scale the displayed process variable. It defines the displayed value when the process variable input is at its maximum value (e.g. if 4 to 20mA represents 0 to 14pH, this parameter should be set to 14). The value can be set anywhere from -1999 to 9999 and can be set to a value less than (but not within 100 LSDs of) the Scale Range Lower Limit, in which case the sense of the input is reversed. Also refer to: Control Action, Control Type, Correcting Variable, Direct Acting Control, On-Off Control and Proportional Control. Settings = -1999 to 9999 Default value = 1000. For thermocouple and RTD inputs, this parameter is used to reduce the effective span of the input. All span related functions work from the trimmed input span. The parameter can be adjusted within the limits of the range, but not less than 100 LSD’s above the Scale RS485 RS485 (also known as EIA-485) is two-wire, half-duplex, multi-drop serial communications connection. RS485 only defines the physical layer electrical specification, not the protocol that is transmitted across it. It uses differential signals (the voltage difference between the wires) to convey data. One polarity indicates a logic 1, the reverse polarity indicates logic 0. The applied voltages can be between +12 V and -7 volts, but the difference of potential must be > 0.2 volts for valid operation. RS485 can span distances up to 1200 metres using inexpensive twisted pair wires. Data speeds can be as high as 35 Mbit/s over 10 m and 100 kbit/s at 1200 m. Range Lower Limit. Settings = Range Max to Min. Default value = Max value of selected temperature range). Also refer to: Engineering Units, Input Range, Input Span, LSD, Process Variable and Scale Range Lower Limit. Scale Range Lower Limit For linear inputs, this parameter is used to scale the displayed process variable. It defines the displayed value when the process variable input is at its minimum value (e.g. if 4 to 20mA represents 0 to 14pH, this parameter should be set to 0). The value can be set from -1999 to 9999 and can be set to a value higher than (but not within 100 LSDs of) the Scale Range Upper Limit, in which case the sense of the input is reversed. It is recommended that the wires be connected as series of point-to-point (multi-dropped) nodes (not in a star or ring format), with 120ohm termination resistors connected across the wires at the two ends of the network. Without termination resistors, reflections of the signals can cause data corruption, and electrical noise sensitivity is increased. The master device should normally provide powered resistors, to bias the wires to known voltages when they are not being driven by any device. Without biasing resistors, the data lines float and noise can be interpreted as data when actually all devices are silent. Settings = -1999 to 9999 Default value = 0. For thermocouple and RTD inputs, this parameter is used to reduce the effective range of the input. All span related functions work from the trimmed input span. The parameter can be adjusted within the limits of the range, but not less than 100 LSD’s below the Scale Range Upper Limit. Converters between RS485 and other formats are available to allow computers to communicate with remote devices. Repeaters can also be used to extend the distance and/or number of nodes on a network. Settings = Range Max to Min. Default value = Min value of selected temperature range). Also refer to: Engineering Units, Input Range, Input Span, LSD, Process Variable and Scale Range Upper Limit. Also refer to: Modbus RTU, and Serial Communications 121 Secondary Proportional Band Also refer to: Control Deviation, Modulating Valves. OnOff Control, Pre-Tune, PI, PID, Setpoint and Tuning. The portion of the input span over which the Secondary Output power level is proportional to the process variable value. The Control action for the Secondary Output is always the opposite of the Primary output. The Secondary Proportional Band is only applicable when Dual Control Type is used. Sensor Break Pre-Set Power If a thermocouple or RTD breaks, or it is disconnected, the instrument detects this condition within 2 seconds, and sets the control output(s) to the value defined by the Sensor Break Pre-Set Power Output parameter in the Control Configuration sub-menu. Process alarms behave as though the PV has gone high. Settings = On-Off Control or 0.5% to 999.9% Default Value = 10%. Also refer to: Control Action, Control Type, On-Off Control, Input Span, Overlap/Deadband, PID, Primary Proportional Band and Tuning. Non-zero based linear inputs (e.g. 2 to10V or 4 to 20mA, but not 0 to 20mA) can also detect a sensor break condition, setting the power to the Pre-Set Power value. Process alarms behave as though the PV has gone low. Self-Tune Self-Tune continuously optimises tuning while a controller is operating. It uses a pattern recognition algorithm, which monitors the control deviation. The diagram shows a typical application involving a process start up, setpoint change and load disturbance. Also refer to: Input Range, Linear Input, RTD and Thermocouple. Serial Communications Configuration A sub-menu of Configuration Mode used to adjust the serial communications parameters. (Addressing, data rate, parity, master/slave settings and write enabling). Temperature Setpoint 2 Also refer to: Configuration Mode, Serial Communications Setpoint 1 Load Disturbance Serial Communications Option A feature that allows other devices such as PC’s, PLC’s or a master controller to read, or change the instruments parameters via an RS485 or Ethernet network. Setpoint Change Full details can be found in the Serial Communications sections of this manual. Time Figure Self-Tune Operation Figure 52.52. Self-Tune Operation Also refer to: Ethernet, Master & Slave, Modbus RTU, Modbus TCP, PLC, RS485 and Serial Communications Configuration. The deviation signal is shown shaded, and overshoots have been exaggerated for clarity. The Self-Tune algorithm observes one complete deviation oscillation before calculating a new set of PID values. Successive deviation oscillations cause the values to be recalculated so that the controller converges on optimal control. When the controller is switched off, these PID terms are stored, and are used as starting values at the next switch on. The stored values may not always be ideal, if for instance the controller is brand new or the application has changed. In these cases, the user can utilise Pre-Tune to establish new initial values. Self-Tune will then fine-tune these values as it monitors any control deviation. Setpoint The target value at which the instrument attempts to maintain the process variable, by adjusting its control output power (the correcting variable). There can be either one or two setpoints. Local Setpoint 1 and/or an Alternative Setpoint. The Alternative Setpoint can be chosen from Local Setpoint 2 or a remote setpoint input from Auxiliary Input A or B if either of these is fitted. One setpoint can be chosen as active using the defined Setpoint Selection method. Setpoint values are limited by the Setpoint Upper Limit and Setpoint Lower Limits. Use of continuous self-tuning is not always appropriate. For example applications which are frequently subjected to artificial load disturbances, for example where an oven door is likely to be frequently left open for extended periods, can lead to errors in the calculations. In addition, because Self-Tune tunes for full PID control, it is not recommended for valve control applications, which normally require PI control. Also refer to: Alternative Setpoint, Auxiliary Input, Correcting Variable, Local Setpoints, Process Variable, Remote Setpoint, Scale Range Lower Limit, Setpoint Lower Limit, Setpoint Upper Limit and Setpoint Select Setpoint Upper Limit The maximum value allowed for setpoints. It should be set to keep the setpoint below a value that might Self-Tune cannot be engaged if the instrument is set for On-Off Control. 122 Setpoint Selection cause damage to the process. The adjustment range is between Scale Range Upper Limit and the Setpoint Lower Limit. If the value is moved below the current value of a setpoint, that setpoint will automatically adjust to keep within bounds. Settings = Within Input Span Range Upper Limit There can be either one or two setpoints. These can be Local Setpoint 1 or an Alternative Setpoint chosen from either Local Setpoint 2 or a remote setpoint input from Auxiliary Input A or B if these are fitted. The Setpoint Select parameter in the control sub-menu defines whether the Active Setpoint will be the Local Setpoint 1 only, the Alternative Setpoint only or if the choice of active setpoint will be made from a digital input or an Operation Mode selection screen. Default Value = Scale Also refer to: Input Span, Scale Range Upper Limit, Setpoint and Setpoint Lower Limit. Also refer to: Active Setpoint, Alternative Setpoint, Auxiliary Input, Digital Input, Local Setpoints, Remote Setpoint, Setpoint. Setpoint Lower Limit The minimum value allowed for setpoints. It should be set to keep the setpoint above a value that might cause damage to the process. The adjustment range is between the Setpoint Upper Limit and the Scale Range Lower Limit. If the value is moved above the current value a setpoint, that setpoint will automatically adjust to keep within bounds. Settings = Within Input Span Range Lower Limit Setup Wizard A sub-set of the Configuration Menu parameters chosen to allow inexperienced users to easily set the instrument up for most simple applications. The parameters shown depend on the options installed. Default Value = Scale The Setup Wizard runs automatically at first ever power-up or whenever a Reset To Defaults is carried out. A partial Wizard also runs whenever option modules have been changed. The partial wizard only shows parameters affected by the changes made. The full Setup Wizard can also be run manually from the Main Menu (this requires entry of an un-lock code). Also refer to: Input Span, Scale Range Lower Limit, Setpoint and Setpoint Upper Limit. Setpoint Ramp Editing Enables or disables the viewing and adjustment of the setpoint ramp rate in Operation Mode. This parameter does not disable the ramping SP feature; it merely removes it from Operation Mode. It can still be viewed and adjusted in the Control Configuration sub-menu. To turn off ramping, the ramp rate must be set to OFF. Once completed, the Setup Wizard exits to Operation Mode. Experts or users with more complex applications should select the parameters they wish to set-up from the Configuration Menus instead of using the Wizard. Settings = Enabled or Disabled Default Value = Disabled Refer to the Setup Wizard information in the Configuration & Use section. Also refer to: Control Configuration, Operation Mode, Process Variable, Setpoint and Setpoint Ramp Rate. Also refer to: Lock Codes, Configuration Menu, Main Menu, Operation Mode and Reset To Defaults. Setpoint Ramp Rate Solid State Relay (SSR) The rate at which the actual setpoint value will move towards its target value, when the setpoint value is adjusted or the active setpoint is changed. With ramping in use, the initial value of the actual setpoint at power up, or when switching back to automatic mode from manual control, will be equal to the current process variable value. The actual setpoint will rise/fall at the ramp rate set, until it reaches the target setpoint value. Setpoint ramping is used to protect the process from sudden changes in the setpoint, which would result in a rapid rise in the process variable. Settings = 1 to 9999 LSDs per hour. = OFF An external device manufactured using two Silicone Controlled Rectifiers in reverse parallel. They can be used to replace mechanical relays in most AC power applications. Some special SSRs can switch DC, but most cannot. As a solid-state device, an SSR does not suffer from contact degradation when switching electrical current. Much faster switching cycle times are also possible, leading to superior control. The instrument’s SSR Driver output provides a time-proportioned 10VDC pulse for to the SSRs signal input terminals. This causes conduction of current from the line supply through the SSR to the load, when the pulse is on. Default Value Also refer to: Cycle Time, Time Proportioning Control, Relay, and Triac. Also refer to: Active Setpoint, Actual Setpoint, LSD, Manual Mode, Process Variable, Setpoint, Setpoint Ramp Editing and Setpoint Selection. Solenoid Valve An electromechanical device, use to control the flow of gases or liquids. It has just two states, open or closed. Usually, a spring holds the valve closed until a cur123 rent is passed through the solenoid coil forces it open. Standard process controllers with time-proportioned or On-Off outputs can be used to control these types of valves. ear mA or voltage output signal can be controlled. Solenoid valves are often used with high/low flame gas burners. A bypass supplies some gas at all times, but not enough to heat the process more than a nominal amount (low flame). A controller output opens the solenoid valve when the process requires additional heat (high flame). Time Proportioning Control Also refer to: Control Deviation, Linear Output, Modulating Valve, and Valve Motor Control Time proportioning control is accomplished by cycling the output on and off during the prescribed cycle time, whenever the process variable is within the proportional band(s). The PID control algorithm determines the ratio of time (on vs. off) to achieve the level of the correcting variable required to remove the control deviation error. E.g. for a 32 second cycle time, 25% power would result in the output turning on for 8 seconds, then off to 24 seconds. This type of output might be used with electrical contactors, solid state relays or solenoid valves. Time proportioning control can be implemented with Relay, Triac or SSR Driver outputs for either primary or secondary outputs. Also refer to: Modulating Valves, On-Off Control and Time Proportioning Control. Supervisor Mode Supervisor Mode allows access to a lock code protected sub-set of the main configuration parameters. The unlock code is different from the higher level Configuration Menu unlock code. Up to 50 Configuration Menu parameters can be chosen for inclusion in Supervisor Mode using the PC configuration software. If none have been chosen, this mode is disabled. Also refer to: Control Deviation, Correcting Variable, Current Proportioning Control, Cycle Time, PID, Primary Proportional Band, Relay, Secondary Proportional Band, Solenoid Valve, SSR and Triac. Refer to the Supervisor Mode information in the Configuration & Use section. Trend Display Also refer to: Configuration Menu and Lock Codes Trend View is a graphical representation of recent process conditions. This feature is available on all variants. It does not rely on the Data Recorder option, and does not retain the stored data if the power is turned off. The trend shows the most recent 120 out of 240 stored data points. Its scale adjusts automatically for the best resolution for the visible data. This data can be the process variable; process variable & setpoint (shown as a doted line), or the minimum and maximum value of the process variable measured since the last sample. Any active alarm(s) are indicated above the graph. The user can scroll the right hand cursor line back to examine all 240 data points. The sample interval and data to display is set in Display Configuration. Thermocouple A temperature sensor made from two different metals. They convert temperature difference between their cold junction (the measuring instrument) and the hot junction, into a small signal or a few microvolts per °C. Thermocouples are cheap and interchangeable, but the wires and connectors used must match the metals used in their construction. They can measure a wide range of temperatures; some thermocouples can withstand very high temperatures such as furnaces. The main limitation of thermocouples is accuracy. The temperature measured by the thermocouple can be displayed as °C; °F or °K. Also refer to: Alarm Types, Display Configuration, Operation Mode, and Process Variable, Setpoint. The color codes for the common types are shown in the Thermocouple Wire Identification Chart in the Electrical Installation Section of this manual. Tuning Also refer to: Engineering Units, Input Range, Process Input and RTD. PID Controllers must be tuned to the process in order for them to attain the optimum level of control. Adjustment is made to the tuning terms either manually, or by utilising the controller’s automatic tuning facilities. Tuning is not required if the controller is configured for On-Off Control. Three Point Stepping Control Modulating valves normally require a special “Three Point Stepping” control algorithm. This which provides an output to move the valve further open, or further closed whenever there is a control deviation error. When this error is zero, no further output is required to maintain control unless load conditions change. This type of controller is often called a Valve Motor Drive controller. This instrument does not currently have a three point stepping algorithm. Also refer to: Auto Pre-Tune, Controller, Derivative Action, Integral Action, On-Off control, PID, Pre-Tune, Primary Proportional Band, Self-Tune, Secondary Proportional Band and Tuning Menu. Tuning Menu The Tuning Menu can be accessed from the Main Menu. This menu is lock code protected. However, modulating valves that have a valve positioning circuitry to adjust the valve position from a DC lin- It gives access to the Pre-tune, Auto Pre-Tune and Self124 tune facilities. These assist with PID tuning, by setting up Proportional band(s), Integral and Derivative parameter values. Tuning is not required for On-Off control. If the Data Recorder option is present, the recordings can be downloaded to the stick for transport to the users PC for analysis. If the Profiler option is present, profiles can be downloaded to the stick or upload to the instrument using a pre-stored file that was downloaded earlier, created using the PC software, or even taken from another instrument. Pre-tune can be used to set PID parameters approximately. Self-tune may then be used to optimise the tuning if required. Pre-tune can be set to run automatically after every power-up by enabling Auto Pre-Tune. Refer to the Automatic Tuning information in the Configuration & Use section. Refer to the USB Menu information in the Configuration & Use section. Also refer to: Auto Pre-Tune, Derivative Action, Integral Action, Lock Codes, Main Menu, On-Off control, PID, Pre-Tune, Primary Proportional Band, Self-Tune, Secondary Proportional Band and Tuning Menu. Valve Motor Drive Control (VMD) Also refer to: Data Recorder, Lock Codes, Main Menu and Profiler This instrument can only control modulating valves that have a valve positioning circuitry that adjusts the valve position according to the level a DC linear mA or voltage output signal. Such valves normally require PI control instead of full PID. Triac A small internal solid state relay, which can be used in place of a mechanical relay in applications switching low power AC, up to 1 amp. Like a relay, the output is time proportioned, but much faster switching cycle times are also possible, leading to superior control. As a solid-state device, a Triac does not suffer from contact degradation when switching electrical currents. A snubber should be fitted across inductive loads to ensure reliable switch off the Triac. A triac cannot be used to switch DC power. Motorzed modulating valves that do not have this type of circuit require special Valve Motor Drive controllers which have a “Three Point Stepping” control algorithm. Solenoid valves can also be controlled using the standard PID algorithm as they behave in a similar way to relays, having just two states, open or closed. Also refer to: Cycle Time, Relay, SSR and Time Proportioning Control.

Instrument Simulation A fully functional and interactive instrument simulation is included with the software. This is linked to a simulated process, allowing changes to a configuration to be tested before use. Figure 57. 4080 Simulation Configuring The Connection A front mounted USB port is available on some models; this can also be used to configure the instrument or transfer profile files, via a USB memory stick. The software can communicate with the instrument via the RJ11 configuration socket located on the underside of the case, or via the Modbus TCP or RS485 communications options if either is fitted. Refer to the wiring section for connection details. The configuration lead/socket is not isolated from the process input or SSR Driver outputs. It is not intended for use in live applications. The configuration socket is intended for initial configuration of the instrument before installing in the application. An RS232 to TTL lead (available from your supplier) is required connect from the PCs RS232 serial port to this socket. 130 A communications settings screen is shown whenever the user attempts to connect to the instrument from the software. The settings must be correct in order for communications to work successfully. First correctly select Configuration Socket or Bus as the Device connector, and select the PC Serial Com port that you have connected to For Modbus TCP, select Ethernet (bus coupler). If connecting via the configuration port, the Start and Stop bits must be 1 and Data bits 8. Parity must be None and address 1. The data bit-rate should be 4800 if Slot A is fitted with an Auxiliary input, 9600 if the Ethernet option is installed or 19,200 for a Digital Input or if Slot A is empty. If the instrument has an RS485 module fitted, the Address, Parity and Bit rate values must match those of the instrument (even if you are connecting via the configuration port). The Start and Stop bits must be 1 and Data bits 8. If connecting via the Modbus TCP module, enter the instrument’s IP address and set the Port address to 502 USB Memory Stick Folders & Files be in any folder of your choosing. The USB option also limits the file name to 8 characters plus the 3 digit . bct or .pfl extension. Longer file names will be truncated. If a USB memory stick is to be used to transfer files between the instruments and/or the software, the files must be stored in specific DEVICE, CONFIG and PROFILE folders on the USB stick. When saving files from the software to the memory stick, ensure that you save them to the correct folder. Local storage on you PC can When saving a file, the data will be overwritten If the file name already exists. DEVICE – This Root of the USB CONFIG – Conf PROFILE – Pro DEVICE – This folder must be located in the RECORDER – R Root of the USB memory stick These can be cr CONFIG – Configuration files (*.bct) PROFILE – Profile program files (*.pfl) RECORDER – Recorder log folders/files. These can be created or saved from the PC software. 131 software. Network Configuration For Modbus TCP Options If your network assigns IP addresses automatically, pressing the “Search Network” button will list any of the Graphical Controllers connected to it. If the instrument has the Modbus TCP communications option fitted, an IP address must be assigned to it in order for it to communicate with the Modbus TCP master device over your Ethernet network. The instrument can automatically receive an IP address if your network is set up to assign addresses to Ethernet devices connected to it. Alternatively, a fixed IP address can be assigned to it manually. Their Network IP Address and MAC Addresses are also shown. For most fixed networks, only instruments that have the same numbers in the first 3 Octets of their IP address can be seen by the PC. In this case, use the method detailed in the “Fixing An IP Address” section below. Highlight the instrument that you wish to configure in the list and press the “Configure Selected Device Button”. The Graphical Controller Ethernet Configuration tool is provided in order to discover or assign the IP Address of the instrument and configure the settings. The Current IP address on the network is shown in the Edit IP Address tab, as is the current configured IP address. A configured address of 0.0.0.0 means the instrument does not have a fixed address, allowing it to receive one from the network (via a DHCP, BootP or AutoIP server). Setting the IP Address Install and run the Graphical Controller Ethernet Configuration software on your PC. Connect the instrument to your network by plugging an Ethernet cable into the RJ45 socket on the top of the case. If your PC is not connected to a network, the instrument can be connected to its Ethernet port directly. Set the value to 0.0.0.0 for automatic addressing, or set a new fixed IP address and press Apply. Note: If this number does not match your PC’s network addresses, further communication with the instrument will cease. 132 Instrument Details The Details tab can be used to confirm communications with the instrument. When opened or refreshed, this tab collects the instruments Serial Number, Date of Manufacture and the Contact Details information, confirming that the Modbus TCP communications is functioning correctly. Fixing An IP Address Edit Modbus Settings *If your instruments 12 digit MAC Address isn’t know, it can be found on a label attached to the RJ45 connector of its Ethernet module. If your instrument cannot be found using the “Search Network” button, the IP address can be set from the Set IP Address option on the software’s System menu. Enter its MAC Address* and the new IP Address (use 0.0.0.0 for automatic addressing) then press okay. The Edit Modbus Settings tab configures the connection between the Ethernet module and the instrument’s microprocessor. These settings MUST match with the settings in the instruments Communications Configuration menu. A faster baud rate can be used if large amounts of data are to be sent between the instrument and the master, but in most cases, it is recommended that the default settings are used.
