1 Introduction
This product is a 1/4 DIN size (96 x 96mm front) micro­processor based graphical process controller, featuring a 160 x 80 pixel, monochrome LCD with dual color (red/ green) backlight. It operates from 100-240V at 50/60 Hz or 24V-48V AC/DC, depending on the model pur­chased. It can measure and control up to two process variables from a variety of sources such as tempera­ture, pressure, flow and level. Primary and secondary control outputs are possible for each loop.
Optional features include a second process input, USB interface, remote setpoint inputs RS485 or Ethernet communications, profile control and data recording. Control options include cascade, ratio and 3-point stepping valve control. Automatic tuning or 5 stage gain-scheduling are also available.
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 or profiler options are fit­ted, recordings and profile information can be trans­ferred via the memory stick.
The data recorder option allows the user to make re­cordings of the processes over time. Recordings can be transferred to a memory stick using the USB inter­face or downloaded via 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 levels for the control loop(s)
over time, increasing, decreasing or holding their val­ues as required. When combined with the real-time clock (part of the Data Recorder option) the profiling capabilities are expanded to allow automatic program start at a defined time and day.
Inputs are user configurable for thermocouple and RTD probes, as well as linear process signal types such as mVDC, VDC or mADC. Two-point calibration or multi­point scaling can compensate for errors or non-linear signals. Output options include single or dual relays, single or dual SSR drivers, triacs or linear mA/V DC. These can be used for process control, alarms/events 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 stabilized excitation for external signal transmitters.
Up to 7 alarms can be defined 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, PID power or signal break types. Alarm status can be indicated by lighting an LED, changing the display backlight color or viewing the active alarm status screen. These alarms can be linked to any suitable output.
Configuration for basic applications is possible using the easy Setup Wizard run automatically at first power­up or manually later. Access to the full range of param­eters is via a simple menu driven front panel interface, or the PC based configuration software.
2 Installation
ELECTRIC SHOCK/FIRE HAZARD. Read and understand all instructions before ine installa­tion, servicing or operating controller. Failure to do so could result in personal injury or death and/or equipment or property damage.
Unpacking
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 servicing.
2. The instrument is supplied with a panel gasket and
push-fit mounting clamp. A multi-page concise manual is 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.
Installation
ELECTRIC SHOCK/FIRE HAZARD. 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). Failute to follow these instructions could result in personal in­jury or death or equipment/property damage.

Figure 1. Main Dimensions
Gasket
Mounting Panel
Panel-Mounting
The mounting panel must be rigid and may be up to
6.0mm (0.25 inches) thick. The cut-out size is:
92mm x 92mm (+0.5mm / -0.0mm).
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 10mm 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.
Ensure the inside of the panel remains within the instrument operating temperature and that there is adequate airflow to prevent overheating.
Note: For an effective IP66 seal against dust and moisture, ensure gasket is well compressed against the panel, with the 4 tongues located in the same ratchet slot.
Do not remove the panel gasket, as this may result in inadequate clamping and sealing of the instrument to the panel.
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 Plug­in Modules section.
Cleaning
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.

3 Field Upgrade Options
Plug-Modules and Upgradeable Functions
Plug-Modules can be either pre-installed at the time of manufacture, or retrofitted in the field to expand the capabilities of the controller. Contact your supplier to purchase these items. Part numbers and circuit board identification numbers for the plug-in modules and ac­cessories are shown in below:
Table 1. Options and Accessories
Plastic pegs prevent fitting of older non-rein­forced single relay modules (Board Identifica­tion Numbers 637/01 and 638/01). Fitting the older relay modules reduces the isolation rat­ing to Basic 240V Isolation and is therefore not recommended. Remove this peg when fitting Dual Relay Modules.

This product is designed to allow the user to recon­figure some hardware options in the field by changing the plug-in modules in slots 1, 2, 3, & A located on the power supply and 1st universal input boards. The main boards (display/CPU, power supply, inputs 1 & 2 and digital input/USB) are factory fitted, but may be removed while reconfiguring the plug-in modules. Take care when re-fitting these boards. Observe the power supply board transformer color, and case labelling to check the supply voltage, otherwise irreparable dam­age may occur.
ELECTRIC SHOCK HAZARD. Disconnect all power before installing or servicing controller. Failure to do so could result in personal injury or property damage.
1. Grip the edges of the front panel (there is a finger grip on each edge) and pull it forwards approxi­mately 10mm, until the Front Panel Removal Latch prevents further movement. The purpose of the latch is to prevent removal of the instrument without the use of a tool.
2. The Front Panel Removal Latch must be pushed down to allow removal of the instrument. Using a tool (e.g. screwdriver or pen tip), press down it down through the front central ventilation hole. This will release the instrument from the case.
3. The internal boards can now be accessed. Take note of the orientation of the instrument and boards for subsequent replacement into the housing. The positions of the boards, their mountings and the Front Panel Removal Latch are shown above.
Replacement of boards must be carried out by a technically competent technician. If the Pow­er Supply board does not match the labelling, users may apply incorrect voltage resulting in irreparable damage.
Removing/Replacing Option Modules
1. To remove or replace Plug-in Modules 1, 2, 3 or A it
is necessary to detach the power supply and input boards from the front panel by lifting first the upper and then lower mounting struts.
2. Remove or fit the modules to the connectors on the power supply and input boards. The location of the connectors is shown below. Plastic pegs prevent fitting of older nonreinforced single relay modules – Remove the peg to fit dual relay modules
3. Assemble the Power Supply and Input boards to­gether. Tongues on each option module locate into slots cut into the main boards, opposite each of the connectors. Hold the Power and Input boards to­gether and relocate them back on their mounting struts.

4. Push the boards forward to ensure correct connec­tion to the front Display/CPU board and re-check the installation of the Option C and/or 2nd Input / Base Option 2 boards if present.
Check for correct orientation of the modules and that all pins are located correctly.
Replacing the Instrument in its Housing
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.
Servicing of the Data Recorder/RTC circuit and replacement of the lithium battery should only be carried out by a technically competent tech­nician.
ELECTRIC SHOCK HAZARD. Disconnect all power before installing or servicing controller. Failure to do so could result in personal injury or property damage.
With the required option modules correctly located into their respective positions the instrument can be replaced into its housing as follows:
1. Hold the Power Supply and Input boards together.
2. Align the boards with the guides in the housing.
3. Slowly and firmly, push the instrument into position
in its case.
Ensure that the instrument is correctly ori­entated. A mechanical stop will operate if an attempt is made to insert the instrument in the wrong orientation, this stop MUST NOT be over-ridden.
Auto Detection of Plug-in Modules
The instrument automatically detects which plug-in modules have been fitted into each slot. The menus and screens change to reflect the options compatible with the hardware. The modules fitted can be viewed in the product information menu, as detailed in the Prod­uct & Service Information Mode section of this manual.
Profiler Enabling
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.
Entering the Profiler Enable Code
Hold down the and keys during the power-up “splash screen”.
Using the or keys, enter the 16-character li­cence code in the displayed screen.
Press to move on to the next character. Press to move back to the previous character.

4 Electrical Installation
ELECTRIC SHOCK/FIRE HAZARD. 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). Failure to follow these instructions could result in personal injury or
death and/or equipment / property damage.
Avoiding EMC Problems
This controller has passed EMC compliance tests to EN61326. There should be no difficulty achieving this level of compliance in use, but it should be borne in mind that the wiring of the installation can significantly reduce the efficiency of instrumentation immunity due to the ease with which high frequency RF can enter via unprotected cables.
The following general recommendations can reduce the possibility of EMC problems.
1. If the instrument is being installed in existing equip­ment, wiring in the area should be checked to en­sure that good wiring practices have been followed.
2. The controller should be mounted in a properly earthed metal cabinet. All round metal shielding is important, so the cabinet door may require a con­ductive sealing strip.
3. 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.
4. Consider using a separate isolation transformer to feed only the instrumentation. A transformer can protect instruments from noise found on the AC power supply.
tween them. If wires MUST cross each other, ensure they do so at 90 degrees to minimize interference.
Keep signal cables as short as possible. If an earthed thermocouple is used or if the sensor has a screened cable, it should be earthed at one point only, preferably at the sensor location or cabinet entry point, by means of a metal gland. Ideally all analogue and digital signals should be shielded like this, but for unscreened cables, large diameter ferrite sleeves at the cabinet entry point are an effective method of reducing RF interference. Looping cables through the ferrite sleeves a number of times improves the efficiency of the filtering. For mains input cables the fitting a suitable mains filter can pro­vide good results.
Noise Suppression at Source
If possible, eliminate mechanical contact relays and replace with solid-state relays. Noise-generating de­vices such as Ignition transformers, arc welders, mo­tor drives, relays and solenoids should be mounted in a separate enclosure. If this is not possible, separate them from the instrumentation, by the largest distance possible.
Many manufacturers of relays, contactors etc supply ‘surge suppressors’ to reduce noise at its source. For those devices that do not have surge suppressors sup­plied, Resistance-Capacitance (RC) networks and/or Metal Oxide Varistors (MOV) may be added.
Inductive coils: MOVs are recommended for transient suppression in inductive coils. Connect as close as possible, in parallel to the coil. Additional protection may be provided by adding an RC network across the MOV.
Cable Isolation & Protection
Four voltage levels of input and output wiring may be used with the unit:
1. Analog inputs or outputs (for example thermocou­ple, RTD, VDC, mVDC or mADC)
2. Relays & Triac outputs
3. Digital Inputs & SSR Driver outputs
4. AC power
The only wires that should run together are those of the same category.
If any wires need to run parallel with any from another category, maintain a minimum space of 150mm be-
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.

Figure 6. Contact Noise Suppression
Sensor Placement (Thermocouple or RTD)
If a temperature probe is to be subjected to corrosive or abrasive conditions, it must be protected by an ap­propriate thermowell.
Probes must be positioned to reflect the true process temperature:
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 (see the wiring section for details). Two wire RTDs should only be used with lead lengths less than 3 metres.
Use of three wire RTDs is strongly recommended to reduce errors do to lead resistance.
Thermocouple Wire Identification
The different thermocouple types are identified by their wires color, and where possible, the outer insulation as well. There are several standards in use throughout the world, but most regions now use the International IEC584-3 standard.

Special Wiring Considerations for Valve Motor Control
Valve Motor Drive (VMD) controllers require two identi­cal outputs to be assigned to position the valve. One to open and one to close the valve. These outputs can be two single relays, two triacs, two SSR drivers or one dual relay, but it is recommended to use two single re­lays (SPDT change-over contacts), and to interlock the relay wiring as shown. This prevents both motor wind­ings from being driven at the same time, even under fault conditions.
Switching actuators directly connected to the valve motor must only be used up to half of their rated volt­age (see CAUTION below). The internal relay and triac outputs are rated at 240VAC, so the maximum motor voltage when using them in this way is therefore 120V unless interposing relays are used. Interposing relays or other devices used to control the valve must them­selves be rated for twice the motor supply voltage.

5 Powering Up
Ensure safe wiring practices have been followed. When powering up for the first time, disconnect the output connections. The instrument must be powered from a supply according to the wiring label on the side of the unit. The supply will be either 100 to 240V AC, or 24/48V AC/DC powered. Check carefully the supply voltage and connections before applying power
ELECTRIC SHOCK/FIRE HAZARD. The windings of a valve motor effectively form an autotrans­former. This has a voltage doubling effect when power is applied to either the Open or Close terminal, causing twice the supplied voltage at the other terminal. For this reason, switching devices directly connected to the valve mo­tor must only be used up to half of their rated voltage. The maximum motor voltage when us­ing the internal relays/triacs is therefore 120V unless interposing relays are used. Interpos­ing relays or other devices used to control the valve must themselves be rated for twice the motor supply voltage. Failure to follow these instructions could result in personal injury or equipment damage.
Powering Up Procedure
At power up, a self-test procedure is automatically started, during which a splash screen is displayed and the LED indicators are lit. At the first power up from new, a Setup Wizard runs to assist configuration of ba­sic applications (refer to the Setup Wizard section on page 43). At all other times, the instrument returns to the normal operation mode once the self-test proce­dure is complete.
Front Panel Overview
The illustration below shows an instrument fitted with the optional USB socket located to the right of the four keypad buttons. Clean the front panel by washing with warm soapy water and dry immediately. If the USB op­tion is fitted, close the port cover before cleaning.
Display
The instrument has a 160 x 80 pixel monochrome graphical display with dual color (red/green) backlight. The main display typically shows the process variables, setpoints, power / deviation bar graphs or graphical trends during normal operation. There are recorder and profile status screen. The top line of the display has labels for the 4 LED indicators. If desired, the back­light color can be changed to indicate the presence of an active alarm or latched output. Refer to the Display Configuration section.

6 Messages and Error Indicators
Plug-in Module Problems
If an invalid or unknown module is detected in one of the plug-in module slots during the power-up self-test, the message “Fault Found, Press , for details” is shown. This is followed by “Replace faulty module in Module Slot n, Press ,” (where n is the faulty slot location). The Service Contact information is displayed next showing details of who to contact if a fault persists
Replace the module in slot “n”. If this does not solve the problem, return the instrument for investigation.
Do not continue using the product until the the error is resolved.
Sensor Break Detection
Whenever a problem is detected with a process vari­able or auxiliary input connection, the displayed value for that input is replaced with the word “OPEN”; except in Ratio control where an open input 1 or 2 is shown as “x1-Open” or “x2-Open”. See Redundant Input to protect critical processes from sensor faults.
This may be the result of a failed sensor, a broken con­nection or an input circuit fault.
In this condition, the control outputs go to the pre-set power value (see Control Configuration.)
Correct the signal/wiring problem to continue normal operation.
Un-Calibrated Input Detection
The instrument is fully calibrated during manufacture. If a fault occurs and calibration data is lost, the process input displays are replaced with the word “ERROR” and error is shown instead of “Calibrated” for effected inputs in Service & Product Information mode.
In this condition, the control outputs go to the pre-set power value (see Control Configuration).
Perform a full base calibration of the input be­fore continuing normal operation. If the problem persists, return the instrument for servicing.
PV Over-Range or Under-Range Indication
If a measured process input value is more than 5% above than the Scaled Input Upper Limit, its value is replace by the word “HIGH” to indicate that it is out of range.
If a measured process input value is more than 5% below than the Scaled Input Lower Limit, its value is replaced by the word “LOW” to indicate that it is out of range.
Auxiliary Input Over-range or Under-range Indication
If the auxiliary Remote Setpoint input is more than 5% above than the Auxiliary Input Upper Limit, its value is replaced by the word “HIGH” to indicate that it is out of range.
If the auxiliary Remote Setpoint input is more than 5% below than the Auxiliary Input Lower Limit, its value is replace by the word “LOW” to indicate that it is out of range.
Cascade-Open
“Cascade Open” is shown on the main screen if the internal link has be severed between cascaded master and slave control loops. This mode should only be used for diagnostics and slave tuning. Close the cascade for proper operation. Refer to the Cascade Control section for more information.
Profile Not Valid
If the user attempts to run a profile that would take the setpoint beyond the current setpoint limits, the profile will not run and the message “Profile Not Valid” is dis­played at the bottom of the profile status screen.
USB Data Transfer Failure message
If the instrument cannot successfully write to the USB memory stick, the message “Data Transfer Failure” will be displayed. Check that there is adequate disk space on the memory stick, then retry.
If the instrument cannot successfully read data from the USB memory stick, the message “Data Transfer Failure” will also appear. Check that this operation would not cause the maximum number of profiles and/ or segments to be exceeded then retry.

7 Application Setup
Before beginning configuration, consider how the con­troller will be used in your application. For instance, how many control loops are needed, is cascade or ratio control required, will the unit control a valve motor, do you need setpoint profiling etc. Consideration should also be given to the output types, alarms and tuning method.
This section is intended to help with this process, guid­ing you through the major configuration settings. Addi­tional information can be found in the relevant sections of this manual, including the glossary, configuration menus, and dedicated sections for major features. These are listed in the table of contents.
Pre-Commissioning Considerations
An easy Setup Wizard is available for basic applica­tions where the most commonly required parameters are present for adjustment in turn. The wizard has a sub-set of the full configuration menu options. For

If fitted, how will the 2nd input be used?
• One loop only (if the 2nd input not fitted or not used in this application)
• Two independent control loops
• Valve feedback for loop 1
• A “redundant” backup for the 1st input
• Cascaded with the first control loop
• A reference input for ratio control
How will the instrument physically control the process?
• Primary only or primary & secondary control out­puts
• Direct valve motor drive outputs

8 Operation and Configuration Menus
This section contains information on all of the control­ler’s modes and the configuration menus.
Operation Mode
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/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 Status screen shows similar information when using profiles.
Subsequent screens allow the display and selection/ adjustment* of the setpoints. From display configura­tion, a selection of other parameter screens can be made available for operator selection/adjustment*. These include: profile control; cascade open/close; auto/manual control; setpoint ramp rate; setpoint source; control enable; clear latched outputs; data re­cording & status trend views. Optional operator mode screens are marked in the screen lists. Some screens will persist until the user navigates away, others will ‘time-out’ back to the base screen.
* If required, all Operation Mode parameters can be made read only. Otherwise parameters such as set­points can be adjusted within their configured limits.
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.
Navigating and Adjusting Values in Opera­tor Mode
Press to move forward or to move backwards through the available screens.
When a displayed value can be adjusted, use to change its value.
The next/previous screen follows the last parameter. If
no further changes are needed, hold down for >1sec to skip straight to the next/previous screen accepting ALL values shown.
In Trend Views, pressing or moves the cursor line back and forward through the last 240 data points.

This mode is only available if it has been configured from the PC software. Its purpose is to allow selected operators access to a lock-code protected sub-set of the configuration parameters, without providing them with the higher level configuration menu unlock code.
The PC software can copy up to 50 parameters from configuration menus for inclusion in the supervisor mode screen sequence. If the parameter is normally displayed on screen with another parameter, both pa­rameters will appear. It is not possible to configure su­pervisor mode screens without using the software.

Adjusts the value at which the “reset wind-up inhibit” is applied. Above this power level further integral action is suspended. Adjustable from 10 to 100% of PID power. Lower values inhibit overshoot.
Caution: If set too low control deviation can occur (the process
settles, but is offset above or below the setpoint). It this is ob­served, increase the value until the deviation error is removed.

9 Input Calibration & Multi-point Scaling
User Calibration
The process inputs can be adjusted to remove sensor errors or to match the characteristics of the attached process. For each loop, independent use of base (un­adjusted), single point offset or two point calibration strategies are possible, as is the use of multi-point scaling for the displayed values of linear inputs. These parameters are in the Input 1 & 2 calibration sub-menus of Input Configuration Sub-Menu Screens.
Incorrect use of Calibration & Scaling can make the displayed value very different from the actual process variable. There is no front panel indication of when these parameters are in use.
Note: These methods do not alter the internal in­strument calibration. Simply choose Base Calibra­tion to restore normal measured values. Re-calibration of the internal base values is possi­ble, but should only be attempted by qualified per­sonnel as it overwrites the factory calibration – see Base Calibration Adjustment below if you think this may be required.
Re-calibration of the internal base values is possible, but should only be attempted by qualified personnel as it overwrites the factory calibration – see Base Calibra­tion Adjustment below if you think this may be required.
Calibration Reminder
If the Data Recorder feature is fitted, a calibration re­minder can be set for a future date. From this date a daily reminder is shown (and shown at every start-up), until a new date has been set. This is useful in applica­tions that require a regular check of the measured ac­curacy – see Input Configuration Sub-Menu Screens.
Single Point Calibration
This is a ‘zero offset’ applied to the process variable across the entire span. Positive values are added to the reading, negative values are subtracted. It can be used if the error is constant across the range, or the user is only interested in a single critical value. To use, se­lect Single Point Calibration from the input calibration menu, and simply enter a value equal, but opposite to the observed error to correct the reading.

This example shows a positive offset value. For exam­ple: If the process displays 27.8 when it should read 30, The error is -2.2 so an applied offset of +2.2 would change the displayed value to 30.
The same offset is applied to all values, so at 100.0 the new displayed value would be 102.2.

Page 66
Two Point Calibration
This method is used where an error is not constant across the range. Separate offsets are applied at two points in the range to eliminate both “zero” and “span” errors. To use:
1. Measure and record the error at a low point in the process.
2. Measure and record the error at a high point in the process.
3. Go to the first two point input calibration screen.
a. Enter the desired low point value as the Calibra-
tion Low PV value.
b. Enter an equal, but opposite value to the ob-
served error as the Calibration Low Offset to cor­rect the error at the low point.
4. Go to the second two point input calibration screen.
a. Enter the desired high point as the Calibration
High PV value.
b. Enter an equal, but opposite value to the ob-
served error as the Calibration High Offset to correct the error at the high point.

Multi-point Scaling
If an input is connected to a linear input signal (mA, mV or VDC), multi-point scaling can be enabled. This al­lows the linearization of a non-linear signal. – see Input
Configuration Sub-Menu Screens.
The Scale Input Upper & Lower Limits define the values shown when the input is at its minimum and maximum values. Up to 15 breakpoints can scale the input vs. displayed value between these limits. It is advisable to concentrate the break points in the area of the range with the most non-linearity, or an area of particular im­portance to the application.

Next set the 2nd point and display value, followed by the 3rd etc. Continue unit all breakpoints are used or you have reached 100% of the input span. A breakpoint set at 100% ends the sequence.
Base Calibration Adjustment
Calibration of each input type is carried out during manufacture. This can be verified in the Service and Product Info screens.
Re-calibration of the internal base values is possible, but should only be attempted by qualified personnel as it overwrites the factory calibration. For most appli­cations, base re-calibration is not required during the lifetime of the instrument.
Choose values as near as possible to the bot­tom and top of your usable span to achieve maximum calibration accuracy. The effect of any error can grow at values beyond the cho­sen calibration points.

ELECTRIC SHOCK/FIRE HAZARD. Any calibra­tion adjustment must only be performed by personnel who are technically competent and authorized to do so. Failure to follow these instructions could result in personal injury or equipment damage.
The equipment used must be in a known good state of calibration.
Required Equipment
To verify the accuracy of the instrument or to carry out recalibration, a suitable calibration signal source is re­quired for each input type as listed below. Accuracy must be better than ±0.05% of reading:
1. DC linear inputs: 0 to 50mV, 0 to 10VDC and 0 to 20mADC.
2. Thermocouple inputs - complete with 0ºC reference facility, appropriate thermocouple functions and compensating lead wire.
3. RTD inputs: decade resistance box with connec­tions for three-wire input.
Performing a Calibration Check
1. Setup input 1 for the input signal type to be checked.
2. Power up the instrument and correctly connect the
signal source. Leave powered up for at least five minutes for RTD and DC linear inputs, and at least 30 minutes for thermocouple inputs.
3. After the appropriate delay for stabilisation, check the calibration at a number of cardinal points by ap­plying the appropriate input signal. The observed readings should be within the tolerances stated in the specifications.
4. Test the other signal types as above if required.
5. Repeat the process for input 2 if fitted.
Recalibration Procedure
For each process input, recalibration is carried out in six phases as shown in the table below; each phase corresponds to a basic input type.

1. For optimum accuracy, leave the instrument power-up
for >30 minutes to warm up before beginning the cali­bration, and then toggle the power off/on to restart the instrument.
2. During the power-up “splash screen”, press and
together until the Input 1 Calibration Status screen
is displayed.
3. Correctly connect the 1st phase signal (50mV), then
press to select the first phase
4. Press + to initiate the calibration.
5. During calibration the message “50mV DC Input Cali-
brating” will display for a few seconds. This should be followed by the “Calibration Successful” confirmation.
6. If the input is misconnected or an incorrect signal is ap­plied, the calibration will be aborted and the values will not be altered. The display will show “Failed: Signal Too Small!” or “Failed: Signal Too Large!”. Correct the problem and repeat that phase before continuing.

10 Digital Inputs
Digital inputs are driven to one of two states (active or inactive) by an applied voltage signal or a contact opening/closing.
A total of 9 physical digital inputs are possible on this instrument. A multiple digital input can be installed at time of purchase, and a single plug-in module can be fitted in option slot A.
Digital Signal Type
The digital inputs can be connected to volt-free con­tacts, or to a voltage signal (compatible with TTL). They can often be used in parallel with equivalent menu se­lections, where either can change function status.
Some inputs are level sensitive, while others are edge sensitive requiring a High to Low or Low to High transi­tion to change functions status. Pre-Tune is always off at power-up (except if auto pre-tune is enabled), but other edge sensitive functions retain their power off status at power on. See the tables below for details.

The four soft digital inputs can be configured by com­bining physical inputs, alarms & events using Boolean logic. Input AND selections are then globally OR’d with the input OR selections, the alarms & the events. By using the invert inputs function, NAND & NOR equiva­lents can be created.
Digital Input Functions
Some or all of inputs C1 to C7 can be used for profile selection. If used in this way they cannot be used for any other functions. Soft inputs and any physical digital inputs not allocated for profile selection can be used to change the instrument status. Each input can only perform a single function.

Profile Selection via Digital Inputs
For instruments with the profiler option, the multi-digital input option can be used to select the profile to run using either a standard binary bit pattern, or binary coded decimal from BCD switches. Profile selection inputs are all level sensitive ( ), with a high/open signal equating to a binary 1 (assuming non-inverted), and a low/closed signal equating to a binary 0 (assuming non-inverted).
Profiles are numbered 0 to 63. Select inputs C1 to Cn for the required number of profiles, from the table:

(0 to 63)
A single BCD switch can be used to select profiles 0 to 9 using C1 to C4, with a bit pattern identical to standard binary. For larger numbers, a double BCD switch arrangement is needed. A separate binary pattern is applied to C5 to C7 for the “tens” digit (10 = 001, 20 = 010, 30 = 011 etc). Any number combination higher than 63 is invalid.

11 Cascade Control
Applications with long time lags (e.g. with two or more capacities such as heated jackets) can be difficult to control with a single control loop. The solution is to split the process into two or more cascaded loops consist­ing of a Master and Slave(s) acting on a common ac­tuator. Ideally, the slave loop’s natural response time should be at least 5 times faster than the master.
The master controller measures the process tempera­ture and compares it to the desired product setpoint. Its correcting variable (0 to 100% PID output) becomes the slave’s effective setpoint (scaled to suit the pro­cess). This setpoint is compared to the slave’s process input, and the controlling actuator is adjusted accord­ingly.
Note: Cascade control is only available on models fitted with the 2nd control loop. The master loop uses input 1; and the slave loop uses input 2.
Example Cascade Application
In this example the controlling actuator is a heater, indirectly heating the product via an oil jacket. The maximum input to the slave represents 300ºC, thus restricting the jacket temperature. At start-up the mas­ter compares the product temperature (ambient) to its setpoint (250ºC) and gives 100%. This sets the maxi­mum slave setpoint (300ºC), which is compared to the oil temperature (ambient) and the slave requests maxi­mum heater output.
As the oil temperature rises towards the slave setpoint, its output falls. Gradually, the product temperature will also begin rising, at a rate dependant on the transfer rate/lag between the oil jacket and the product. Eventu­ally this causes the master’s PID output to decrease, reducing the slave setpoint. The oil temperature is re­duced towards the new slave setpoint. This continues until the system becomes balanced. The result is quick­er, smoother control with the ability to cope with chang­es in the load. Overshoot is minimized and the jacket temperature is kept within acceptable tolerances.
Normal Cascade Operation
During operation, the master and slave are coupled to­gether and. “Cascade” is displayed. The master pro­cess value and setpoint are most relevant to the user. The master setpoint is directly adjustable. The process value of the slave controller is displayed for information only.
Cascade-Open
The cascade can be disconnected (via digital inputs or menu selection), switching from normal operation to di­rect control of the slave. “Cascade-Open” is displayed. Opening the cascade is “Bumpless”. The current cas­cade value is used as the initial slave setpoint (dis­played as “SlaveSP”). The process is then controlled and adjusted solely by the slave controller using this setpoint. Switching back to Cascade is also bumpless.

In either case the slave control loop must first be opti­mized on its own, followed by the master loop in com­bination with the previously tuned slave.
To automatically pre-tune a cascade:
1. Go to the Automatic Tuning menu
2. Select “Cascade-Open” from the pre-tune menu to
tune the PID set(s) on the slave.
3. After the slave has successfully tuned, pre-tune the master/slave combination by selecting “Cascade­Closed” from the pre-tune menu.
Note: The cascade remains open until you pre-tune the master or manually select Cascade-Closed.
To manually tune a cascade:
1. Select Cascade-Open from the Cascade Control menu, breaking the link between the master and slave loops.
2. Set the slave controller setpoint manually to the ap­propriate value for your application.
3. Tune the slave for relatively fast control (‘proportion­al only’ is often sufficient).
4. Select Cascade-Closed from the Cascade Control menu to link the master and slave loops, then tune the master/slave combination.

12 Ratio Control
A ratio control loop is used where the quantity of one of the material is to be controlled in proportion to the measured quantity of a second material. The controller mixes the materials at the desired ratio by adjusting the flow of input 1. The flow of input 2 may be controlled separately, but is not controlled by the ratio control loop itself.
The process value used by the controller is therefore determined by the ratio of the two inputs rather than a single measured variable.
Note: Ratio control is available on models with the 2nd Auxiliary Input, or two loop models. The feature and information displayed is optimized for control of burner fuel/air, but can be used in other flow ratio applications.
Stoichiometric Combustion
Below is an example of stoichiometric combustion ra­tio control. For optimum combustion the fuel-air ratio is set so that there are no flammable residues in the waste gas.

fected by this control loop. Atomizing air is fed in with the fuel oil at a constant rate ‘NO’. This must be con­sidered when calculating the correct fuel/air mix. Total airflow is x1 + NO. The stoichiometric factor, SFac is entered to match the desired ratio. E.g for 10 parts total airflow to one part fuel, SFac would be 10.
The setpoint (entered as a relative value such as 1.00) is multiplied by SFac when calculating the control de­viation. E.g. with a setpoint of 1.00 and SFac of 10 the controller attempts to make the physical ratio 10. With a setpoint of 1.03 it would attempt to make the ratio
10.3 for 3% excess air.
The instantaneous (controlled) process value is calcu­lated from the physical ratio, divided by SFac. Like the setpoint, this is displayed as relative value.
E.g. if SFac is 10, with 59.5m3/h airflow measured at x1, 0.5m3/h atomising air applied at NO and 6m3/h fuel is measured at x2, the instantaneous process value would be:
x1 + NO
x2 * SFac
=
59.5 + 0.5
6 * 10
=
1.00
If fuel flow remained at 6m3/h and the setpoint was adjusted to 1.05 (5% excess air), the controller would increase the x1 air flow to 62.5m3/h.
x1 + NO
x2 * SFac
=
62.5 + 0.5
6 * 10

Figure 48. Ratio Control Example
It is normal in this application to display the process value and setpoint as relative values rather than the physical ratio or absolute values. A scaling factor is set such that the displayed value will be 1.00 at the correct stoichiometric ratio for the application.
Inputs 1 and 2 are configured and scaled to match the attached flow meters. In this example a 4 to 20mA sig­nal at x1 represents 0 to 1000m3/h of airflow controlled by a valve. The second 4 to 20mA signal at x2 repre­sents 0 to 100m3/h of fuel oil. The fuel flow is not af-

13 Redundant Input
If the 2nd universal input is fitted, the second input can be configured as a redundant input for the main pro­cess input. This increases process security by protect­ing against the possible loss of valuable product result­ing from sensor failure.
A second sensor is connected to input 2 so that if the main sensor fails, the instrument automatically switch­es to this backup or “redundant” sensor. In this con­dition, if input 1 has a signal break alarm configured it will activate, but any other process input or control status alarms seamlessly switch to the 2nd input. The 2nd input continues to be used until the signal to input 1 is restored.
Note: The user may not even be aware of a sen­sor fault, so it is strongly recommended that signal break alarms are configured for both inputs to pro­vide a notification if problems occur.
The redundant sensor must be of the same type, and be correctly located in the application ready to take over if needed. If the redundant input option is select­ed, the 2nd input cannot be used for other functions.
Note: If both signals are lost at the same time, the PV value display is replaced with “OPEN” and the normal sensor break actions occur.

14 Valve Motor Drive / 3-Point Stepping Control
When directly controlling the motor of a modulating valve or damper, set the Control Mode to VMD in con­figuration mode to enable the 3-point stepping Valve Motor Drive control algorithm.
The term “3-point stepping” is used because there are 3 output states, open valve, close valve or stopped (no action). Switched outputs move the valve further open, or further closed when a control deviation error is de­tected. If the error is reduced to zero, no further output is required until the load conditions change.
VMD mode doesn’t allow on-off control (the minimum proportional band equates to 0.5% of the scaled input span) and usually requires PI control, where the deriva­tive parameter is set to OFF.
Note: Some modulating valves have positioning cir­cuitry to adjust the valve position. These require a DC linear mA or voltage output and use the standard control algorithm (Set Control Mode to Standard).
Special Wiring Considerations for Valve Motor Control
Valve motor drive mode must have two identical out­puts assigned to position the valve. One to open and one to close the valve. These outputs can be two single relays, two triacs, two SSR drivers or one dual relay, but it is recommended to use two single relays (SPDT change-over contacts), and to interlock the wiring as shown. This prevents both motor windings from being driven at the same time, even under fault conditions.

This has a voltage doubling effect when power is applied to either the Open or Close ter­minal, causing twice the supplied voltage at the other terminal. For this reason, switching devices directly connected to the valve motor must only be used up to half of their rated voltage. The max-

imum motor voltage when using the internal re­lays/triacs is therefore 120 V unless interposing relays are used. Interposing relays or other devic­es used to control the valve must themselves be rated for twice the motor supply voltage. Failure to follow these instructions could result in per­sonal injury or equipment damage.
Switching actuators directly connected to the valve motor must only be used up to half of their rated volt­age. The internal relay and triac outputs in this instru­ment are rated at 240VAC Therefore, the maximum mo­tor voltage when using them is therefore 120V unless interposing relays are used. Interposing relays or other devices used to control the valve must themselves be rated for twice the motor supply voltage.
Position Feedback
In VMD mode this instrument uses a boundless (open­loop) 3-point stepping algorithm. It does not require any kind of position feedback in order to correctly con­trol the process and can therefore avoids problems as­sociated with faulty feedback signals.
However, where valve feedback is available it can still be displayed in a bar-graph as a percentage open (0 to 100%). Position feedback is usually provided by means of a potentiometer mechanically linked to the valve. The output of a related flow meter can also be used to indicate the relative valve position. Flow meters typically have linear 0-20/4-20mA or 0-5/0-10V signals. To display the position/flow signal the 2nd input is must be configured for this purpose.
The input is adjusted and scaled to show 0 to 100% representing valve fully closed to fully open, or a flow rate equating to fully closed to fully open. The valve position scaling parameters are set in the Input Con­figuration sub menus.
Valve Limiting
When valve position/flow indication is in use, the signal can be used by the controller to limit the valve move­ment. Upper and/or lower limits can be set beyond which it will not attempt to drive the valve. The valve open and close limits are set in the Control Configura­tion sub menu.
These limits must be used with care. They are effectively control power limits. Do not set val­ues that prevent proper control of the process!

15 Setpoint Sources
The setpoint is the target value at which the instrument attempts to maintain the process variable. Each loop can have a Main “local” setpoint set from the keypad and an Alternate setpoint.
Loop 1 Setpoint Sources
Loop 1 can have a Main “local” setpoint set from the keypad and an Alternate setpoint. The alternate set­point source can be either another local Setpoint or a remote setpoint (RSP), set by a mA or V DC signal ap­plied to the 2nd input or to auxiliary input A. The control loop can only use one setpoint source at a time for each loop. This is called the “Active Setpoint”. If the profiler option is fitted this provides the setpoint when the profiler is in use, replacing both main an alternate setpoints.
Main/alternate setpoint selection can be made via a digital input; from the Control Configuration menu or if enabled in the Display Configuration sub-menu, an operator screen can be used to select the setpoint. The chosen setpoint selection method can be used to per­manently select one of the setpoints, or allow switching between them.
Refer to the Control Configuration Sub-Menu Screens on page 50 for setpoint settings.
Loop 1 Profile Setpoint
When in profile control mode, the selected profile al­ways provides the active setpoint source for loop 1. Once profile control mode is exited, the selected main or alternate setpoint for loop 1 becomes active again.
Loop 2 Setpoint Sources
Loop 2 can have a Main “local” setpoint set from the keypad and an Alternate setpoint. The alternate set­point source can be either another local Setpoint” or a remote setpoint (RSP), set by a mA or V DC signal applied to auxiliary input A. The control loop can only use one setpoint source at a time for each loop. This is called the “Active Setpoint”. If the profiler option is fitted this provides the setpoint, replacing both main an alternate setpoints, when 2-loop profiling is in use.
Main/alternate setpoint selection can be made via a digital input; from the Control Configuration menu or if enabled in the Display Configuration sub-menu, an operator screen can be used to select the setpoint. The chosen setpoint selection method can be used to per­manently select one of the setpoints, or allow switching between them.
Refer to the Control Configuration Sub-Menu Screens for setpoint settings.
Loop 2 Profile Setpoint
If the selected profile was configured to control the setpoint of both loops, it will provide the active set­point source. Once profile control mode is exited, the selected main or alternate setpoint for loop 2 becomes active again.

16 Profiler
This section covers the Profiler (or setpoint program­mer) option. To confirm if profiling is enabled on your controller, refer to the Service & Product Info menu.
Introduction
The Profiler feature 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 their val­ues as required. The profile can control both setpoints if the 2nd control loop is fitted.
Profiler options and screens are added to the Main Menu and Operation Mode.
Profiler Enabling
Controllers supplied without the Profiler option in­stalled can be upgraded by purchasing a licence code number. Refer to the Field Upgrade information.
To obtain the correct code you must tell your supplier the instrument serial number – this can be found in the Service & Product Info menu.
To enter the licence code, hold down the + keys during the power-up splash screen. Enter the 16-character licence code in the displayed screen and
press .
Profile Components
General profile configuration settings apply to all pro­files. They enable or disable “profile editing while run­ning”, and automatic starting of the selected profile if it has been configured with a delay or day & time start trigger.
If delay or day & time start triggers are disabled, pro­files can only be manually started, and this is with im­mediate effect even if they have a delay or day & time trigger defined. If delay or day & time start triggers are enabled, delayed starts are possible, and if the select­ed profile has a day & time trigger it will wait until the time set and before starting.
Note: Even if profile editing is enabled, changes to the current and next segment or a running pro­file will not take effect until the profile is next run. Changes to other segments will take effect imme­diately.
more segments. The header information is unique for each profile, it contains the profile’s name; if it controls just one or both loops; how it should start & stop; the abort & power-loss recovery actions; and how many times it should be repeated.
Note: Profile Header information is only stored to memory as the Segment creation sequence begins. No profile is created if you exit before this point. Segment information is stored as each segment is created, but the profile remains invalid until an end or join segment is defined.
Segment information is stored as each segment is cre­ated, but the profile remains invalid until an end or join segment is defined.
Segments can be ramps, dwells, steps or special seg­ments such as holds, ends, joins or loop-backs.
If the instrument also has the data recorder option, its real time clock (RTC) expands 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.
Profile Starting & Standard Segments
The example profile below explains the standard seg­ment types required to make a simple profile or profile sequence. A Start Trigger is the instruction to begin the selected profile. This can be from the profile control menu, a digital input signal, via a serial communica­tions command or if enabled in the display configu­ration, the profile can be controlled from an operator screen.
Following a Start Trigger, profiles can start immedi- ately, after a delay, or using the Day & Time start timer (Day & Time start available on with the Recorder option only). Following the start trigger, the remaining delay time or the start day & time are shown in the profile status bar-graph until the profile begins running.
Note: Profiles outside current setpoint limits will not run, A “profile not valid” error shows if you attempt to run a profile under these circumstances.

Figure 49. Profile Starting and Standard Segment Types
Ramps and Step Segments have target setpoint that they will reach as they finish. If a segment is a Ramp­Time type, the slope needed to reach the target set­point in the defined time will change depending on the starting setpoint value. For a Ramp-Rate 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 in advance.
Note: When using the instrument as a two loop pro­filer Ramp-Rate type segments are not available. Calculate the time from the starting value to the target setpoint and use Ramp-Time instead.
Step
End
The example below shows how two loop profiling works in practice. Auto-Hold settings and target set­points are independent for each loop, but the segment types and time settings are the same.
A Dwell (often called a “soak”) holds the previous setpoint value for the specified dwell time. Step segments jump straight to the new target setpoint value. An End segment ends the profile or profile sequence. If the last segment is a Join, the “join target” profile will begin running.
Note: If the join target has been deleted the profile sequence will abort and the last profiles abort ac­tion will apply.
Two Loop Profiles
If the instrument is configured to control two control loops, the setpoint of both loops can be maintained when profiling. Both setpoints are synchronized to a common segment time-base, but have independent target setpoints for each of the segments.
Note: When using the instrument as a two loop pro­filer Ramp-Rate type segments are not available. Calculate the time from the starting value to the target setpoint and use Ramp-Time instead.
Seg. u & v shows a ramp and a dwell with the shared time base The ramp direction can be different (Seg. w), and although one loop cannot ramp while the other dwells, a “dwell” is achieved by a ramp with its final setpoint value at the same value as the previous seg­ment (Seg. x). Similarly, if only one loop is to Step to a new value, make the other “step” to its existing set­point value. If you later change the previous setpoint, you may have to change both segments.
The Loop-back feature takes both loops back to the same defined earlier segment.
Note: Auto-Hold settings are independent for each loop. Either loop can cause the profile to auto-hold, holding both loops at the current setpoint value. The profile continues only when both loops are back within their hold bands.

A Loop-back 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 continues onwards. More than one Loop Seg­ment can be used in a profile, but they cannot cross.

Profile Running / Holding vs. Hold Segments
A Hold Segment is a pre-planned hold programmed into the profile. It maintains the value of the previous segment and the profile does not continue until a Con- tinue Trigger occurs. This can be via a key-press, se­rial communications, a digital input signal or after wait­ing until a pre-set time of day (time of day is available with the recorder option only).
The Auto-Hold Feature
There are independent auto-hold settings for each seg­ment of each loop controlled by the profile. When uti­lized, auto-hold ensures that the profile and the actual processes remain synchronized. If the process does not closely match the setpoints (within the defined Hold Bands), the profile will be held until it returns within bounds. When Auto-Hold becomes active, the profile status is shown as “Held”.
Note: The segment time is increased by the time that the process is out of bounds, extending the to­tal profile run time.
Auto-hold can be configured to hold the profile if the process goes beyond the hold band Above the Set-
point only, Below the Setpoint only or it can be set to Band (either side of the setpoint).
Note: For two-loop profiles, either loop can cause the profile to hold. The entire profile (i.e. both loops) will be held if either process is outside of its auto­hold band. It continues only when both loops are back within their auto-hold bands.
Figure 51. Run/Hold & Hold Segments
A Hold condition during a segment maintains the cur­rent profile setpoint value(s). Once the hold condition is stopped the Ramp or Dwell continues. The user can request that the profile holds, or it can be instigated automatically.
Note: A running segment will hold if the operator or a digital input instructs it to. It can also hold due to “auto-hold”, if one of the profile control loops is disabled, if a cascade is set to “open” or if manual control is selected.
Auto Hold Examples
Figure 52. Auto-Hold on a Dwell Segment
During a Dwell, the dwell time is increased 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.

Power/Signal Lost Recovery Actions
Power off or input lost
Power / input returns
If the power is cut or the input signal is lost while a pro­file is running, the instrument will use the defined Pro­file Recovery Method once the signal / power returns. The profile recovery method is set in the profile header.
The possible profile recovery options are explained be­low.
Run (Start-on SP)
Off Time
Note: Recorder versions always use option E (Con­tinue profile) if the “off time” is less than the Profile Recovery Time setting. If the “off time” is longer, the defined Profile Recovery Method is used.
Note: With option E, after the power returns profile bar graph resets and shows the remaining/elapsed time for the profile only since re-starting.

The possible profile end actions are explained below.

17 USB Interface
The features in this section are available on models fit­ted with the optional USB Interface.
Using the USB Port
The USB Interface can be used to upload or download instrument settings to or from a USB memory stick (FAT32 formatted). Easy configuration of multiple in­struments is achieved by copying from one instrument to another, or by transferring data 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 also to the USB menu.
USB Memory Stick Folders & Files
When a USB stick is inserted, the instrument looks for, and if necessary creates the DEVICE, CONFIG, PRO- FILE and RECORDER folders. Files must be located in these folders in order to be used by the instrument. When preparing to upload files from your PC, ensure that you save them to the correct folder on the memory stick.
If the file name already exists, data will be overwritten.
Note: To speed up the disk operation, keep the number of files in these folders to a minimum.
The first recorder log file is named 001-0001.csv. A new file is created with the first 3 digits incremented (e.g. 002-0001.csv; 003-0001.csv etc) each time the data being recorded is changed. The last 4 digits in­crement (e.g. 001-0002.csv; 001-0003.csv etc) if the file size reaches 65535 lines, if a recording is stopped then re-started or if there is a period of >10s without an alarm when recording from an alarm trigger.
Do not remove the memory stick during data transfer. Data corruption may result.
During data transfer, normal operations carry on in the background, but operator access is denied. Transfer of full memory can take up to 20 minutes. Only begin a transfer when access to the instrument (e.g. setpoint changes) will not be required.
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.

Manual
Input
18 Data Recorder
The optional Data Recorder allows the recording of pro­cess conditions to memory over time. It operates inde­pendently from the Trend Views. The recorder includes 1Mb of flash memory to store data when powered down and a real time clock (RTC) with a battery backup.
Servicing of the Data Recorder/RTC circuit and replacement of the internal lithium battery should be carried out by only a trained technician.
Recordable Values
A selection of values can be recorded for each control loop, from: Process Variable; Maximum or Minimum Process Values (since the previous sample); Setpoints; Primary Power, Secondary Power or Auxiliary Input values. Additionally the status of Alarms and Profiler Events can be recorded, as can when the unit is turned On/Off. See the Recorder Configuration sub-menu.
Sampling rates between 1 second and 30 minutes are possible, with the data either recorded until all memory is used, or with a continuous “First In/First Out” buffer overwriting the oldest data when full.
The recording capacity is dependent on sample rate and number of values recorded. For example: Two ana­logue values will recorded for 21 days at 30s intervals. More values or faster sample rates reduce the duration proportionally.
Note: If recorded, each alarm/event change forces an extra sample to be recorded, reducing the remaining recording time available. If these are likely to change often, take this into account when determining if there is sufficient memory available.
Recorder Control and Status
Options for starting/stopping recordings include Manually (from the recorder menu or a screen added to operation mode); a Digital Input; during a Running Profile; or Record on Alarm. See the Recorder Configuration sub-menu.
The recorder control menu allows the manual trigger to be started or stopped, as well as deleting recorded data from memory.
A status screen is shown with current information about the recorder, including if a recording is in progress (Re­cording or Stopped); the recording mode (FIFO or Record Until Memory Is Used); a % memory use bar-graph and the estimated available time remaining based on the data selected and memory used.
Recorder status and manual record trigger control can optionally be added to Operation Mode. This is enabled or disabled in the Display Configuration sub-menu.
Note: The recorder control screens allow the manual trigger to be started or stopped, but recording will continue as long as any trigger that has been config­ured is active.
Uploading Data
Recordings can be transferred to a memory stick using the USB Port. They can also be uploaded directly to the PC software via the configuration port or RS485/Ethernet communications if fitted.
The data is stored in Comma Separated format (.csv) which can be opened and analysed with the optional PC software or opened directly into a spreadsheet. Many third party software programs can also import data in the .csv format.
The file contains a header identifying the source instru­ments serial number, the date of the file upload and de­scriptions of the data columns.
The data columns seen depends on the data selected to record, but will always include the date and time of each sample. The date format follows the instrument date for­mat selection. Date(en) is dd/mm/yyyy, and Date (us) is mm/dd/yyyy.
Note: Analysis with the PC software is limited to 8 ana­logue channels, so only the first 8 will be displayed. The number of recorded alarms & events is not limited.
Additional Features & Benefits from the Recorder
The real time clock (RTC) included with the data recorder also expands the profiling capabilities (see Profiler) and allows a “calibration due” reminder to be shown at a specified date (see the Input Configuration sub-menu).

19 Controller Tuning
PID Sets & Gain Scheduling
Up to 5 sets of PID tuning terms can be entered for each control loop, allowing the instrument to be pre-set for differing conditions. Each set has individual values for the following parameters: Primary Proportional Band; Secondary Proportional Band; On-Off Differential; Inte­gral Time; Derivative time; Overlap/Deadband. The pa­rameter values can be entered in the control configura­tion sub menu (page 50), but also see Automatic Tuning below for automatic tuning of the PID sets.
The PID sets might be configured for different applica­tions, or to allow for differing process or load conditions that might occur in a single application. In this case one set at a time would be selected as the “Active PID” set for that loop.
Alternatively, if the process conditions change signifi­cantly during use (e.g. if it is partially exothermic as the temperature rises) Gain Scheduling can be employed.
Gain scheduling ‘bumplessly’ switches PID sets auto­matically at successively higher setpoint or process val­ues, giving optimal control across a wide range of pro­cess conditions. This is explained in the diagram below.
PID set 1 is used from the scaled input lower limit until the “breakpoint” for set 2 is passed and that set be­comes active.
Set 2 is then used until the breakpoint for Set 3 is reached etc.
If any breakpoint is set to OFF, the subsequent PID sets are not used.
The final set continues from the last breakpoint to the scaled input upper limit.
Gain Scheduling breakpoints can be selected to switch PID sets with a change in the current setpoint value, or the current process value.
Note: ON/OFF control is possible with the individual PID sets but cannot be used with gain scheduling. On/ off control is replaced with the default proportional band if gain scheduling is turned on.
If the a change to the scale lower or upper limits forces any of the breakpoints out of bounds, all breakpoints will be turned off and the instruments uses the default PID set 1.
Automatic Tuning
To automatically optimize the controllers tuning terms for the process, you can use Pre-Tune, Self-Tune or Auto Pre-Tune independently for each control loop.
Note: Automatic tuning will not engage if either pro­portional band is set to On/Off control. Also, pre-tune (including an auto pre-tune attempt) will not engage if the setpoint is ramping, if a profile is running, or if the Process Variable is <5% of span from setpoint.
Pre-Tune
Pre-tune performs a single disturbance of the normal start-up pattern so that a good approximation of the ideal PID values can be made prior reaching setpoint. It automatically stops running when the test is complete. The user chooses which PID set the new tuning terms will be applied to, but this selection does not change the selected “active PID set”. This allows tuning of any PID set for future use before return to control with the current PID set.In VMD mode, derivative is not applied by pre-tune, and the controller is optimized for PI con­trol. In standard control mode, PI & D are all calculated, which may not suit all processes.
There are two pre-tune modes with different process test points. The first is “Standard Pre-Tune” which tests the process response half-way from the activation point (the process value when pre-tune began running) to the current setpoint. The second type is “Pre-Tune at Value” which allows the user to specify the exact point at which the process test will occur.
ELECTRIC SHOCK/FIRE HAZARD. Consider possible process over-shoot when selecting the value to tune at. If there is a risk of damage to the product or equipment select a safe value. Failure to follow these instructions could result in personal injury or equipment damage.

Figure 58. Pre-Tune Operation
Pre-tune is 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.
Note: To pre-tune a cascade, first select “Cascade­Open” to tune the PID set(s) on the slave. After the slave has successfully tuned, remember to pre-tune the master/slave combination (this time select “Cas­cade-Closed”). The cascade remains open until you do this.
Auto Pre-Tune
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. If auto pre-tune is selected, a Standard Pre-tune will attempt to run at every power up, applying new tun­ing terms to the current Active PID set. Auto pre-tune will not be able to test the process if at the time the controller is powered up, either primary or secondary outputs 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. Auto pre-tune is not possible with cascade control mode.
Self-Tune
If engaged, self-tune uses a pattern recognition algo­rithm to continuously monitor and adjust for control deviation. It optimizes the tuning by applying new PID terms to the current Active PID set while the control­ler is operating. In VMD control mode, derivative is not applied by self-tune, and the controller is optimized for PI control.
Figure 59. Self-Tune Operation
77
Page 86
The diagram shows a typical application involving a process start up, setpoint change and load distur­bance. In each case, self-tune observes one complete oscillation before calculating new terms. Successive deviations cause the values to be recalculated con­verging towards optimal control. When the controller is switched off, these terms are stored and used as starting values at switch on. The stored values may not always be ideal, if for instance the controller is new or the application has changed. In this case the user can use pre-tune to establish new initial values for self-tune to fine-tune.
Use of continuous self-tuning is not always appropri­ate. For example frequent artificial load disturbances, such as where an oven door is often left open for ex­tended periods, might lead to calculation errors. In standard control mode, PI & D are all calculated, which may not suit all processes. Self-Tune cannot be en­gaged if the instrument is set for on-off control or with cascade control mode.

Tuning Control Loops - PID with Primary Output only
This technique balances the need to reach setpoint quickly, with the desire 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 controller to give acceptable results in most applications that use a single control device.
This technique is suitable only for processes that are not harmed by large fluctuations in the process variable.
1. Check that the scaled input limits and the setpoint limits are set to safe and appropriate levels for your process. Adjust if required.
2. Set the setpoint to the normal operating value for the process (or to a lower value if an overshoot be­yond this value might cause damage).
3. Select On-Off control (i.e. set the primary propor­tional band to zero).
4. Switch on the process. The process variable will rise above and then 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 diagram below.
5. Calculate the PID control parameters (primary pro­portional band, integral time and derivative time) us­ing the formulas shown.
6. Repeat steps 1-5 for the second control loop if re- quired.
Tuning Control Loops - PID with Primary & Secondary Outputs
This tuning technique balances the need to reach set­point quickly, with the desire to limit setpoint overshoot at start-up and during process changes. It determines values for the primary & secondary proportional bands, and the integral and derivative time constants that al­low the controller to give acceptable results in most applications using dual control (e.g. Heat & Cool).
These techniques are suitable only for pro­cesses that are not harmed by large fluctua­tions in the process variable.
Method 1 – For Simple Processes
Use this method if the process is simple/easily con­trolled and the relative power available from the prima­ry and secondary actuators is approximately symmetri­cal (e.g. if the maximum heating and cooling power is equal)
1. Tune the controller using only the Primary Control output as described in steps 1 to 5 of Manually Tun­ing - PID with Primary Output, above.
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.
3. 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 over-damped (slow to respond) in the region of the secondary proportional band, decrease its value.

4. When the PID tuning values have been determined,
Process Variable

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.
Method 2 – For Asymmetrical Processes
Use this method if the relative power available from the primary and secondary actuators is not symmetri­cal (e.g. if the maximum cooling power is less than the maximum heating power)
1. Check that the scaled input limits and the setpoint limits of the loop in question are set to safe and ap­propriate levels for your process. Adjust if required.
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).
3. Select On-Off control by setting the primary pro­portional band to zero (the secondary proportional band will automatically be set on-off control when you do this).
4. Switch on the process. The process variable will os­cillate about the setpoint. Record the peak-to-peak variation (V) of the oscillation (i.e. the difference be­tween the on-going overshoot and undershoot), the time period of the oscillation (T) in minutes and the maximum rate of rise (dP) and fall (dS) as the oscil­lation continues.
V = On-going Peak-to-Peak variation
T = Time period of oscillation (minutes)
dS = Maximum rate of rise
dP = Maximum rate of fall
R = Ratio dS/dP
Primary Proportional Band = Pb.P = V/R
Secondary proportional band = R x Pb.P
Integral Time = T minutes
Derivative Time = T/6
5. Calculate and enter the PID control parameters (pri-
mary proportional band, integral time and derivative time) using the formulas shown, and observe the process.
6. If symmetrical oscillation occurs, increase the pro­portional bands together, maintaining the same ra­tio. If the asymmetrical oscillation occurs, adjust the ratio between the bands until it becomes symmetri­cal, then increase the bands together, maintaining the new ratio.
7. 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 small positive value to introduce some overlap. Ad­just this value by trial and error to find the minimum value that gives satisfactory results.
Valve, Damper & Speed Controller Tuning
This tuning method is used when controlling devices such as dampers, modulating valves or motor speed controllers. It applies equally to modulating valves with their own valve positioning circuitry, or in VMD mode where the instrument directly controls the valve motor– see Valve Motor Drive / 3-Point Stepping Control. It de- termines values for the primary proportional band, and integral time constant. The derivative time is normally set to OFF. This type of PI Control minimizes valve/mo­tor wear whilst giving optimal process control.
In VMD modem the Motor Travel Time and Minimum On Time must be correctly set to match the valve spec­ifications before attempting to tune the controller.
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).
2. Set the Primary Proportional Band a value approxi­mately equal to 0.5% of the input span for the loop to be tuned. (Span is the difference between the scaled input limits).
3. Set the Integral & Derivative time constants both to OFF.
4. Switch on the process. The process variable should oscillate about the setpoint.
5. Follow the instructions in the diagram below. 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.

Small adjustments can be made to correct minor con­trol problems. These examples assume reverse acting control (e.g. heating). Adjust accordingly for direct ac­tion. If they do not help solve the problem, re-tune the controller as detailed on the preceding sections.
Note: When fine tuning the settings, only adjust one parameter at a time, and allow enough time for the process to settle into its new state each time you change a value.
Cycle Times
A separate cycle time adjustment parameter is provid­ed for the Primary and Secondary control when using time-proportioning control outputs.
If the process oscillates at the same frequency as the cycle time, it indicates it may be too long for the pro­cess. Decrease the cycle time and re-check the period of oscillation, if it has changed to match the new cycle time this confirms that the time is too long.
If the control actuators will accept it, continue reducing the cycle time until the process stabilizes, or no further improvement is seem. Recommended times. Relays
≥10 seconds. SSR Driver 1 second.
Proportional Bands
Increase the width of the proportional bands if the pro­cess overshoots or oscillates excessively. Decrease the width of the proportional band if the process re­sponds slowly or fails to reach setpoint.
Too Narrow: Process Oscillates
Ideal: Stable Process
Note: Adjusting the cycle time affects the controllers operation; a shorter cycle time gives more accurate control, but mechanical control actuators such as re­lays will have a reduced life span.
Slow warm up and response
Integral Time Constant
To find the optimum 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 stabilizes. If not increase the value some more and re-test. If the response is too slow, de­crease the integral time, but avoid instability.

Note: When controlling a modulating valve, it is usually recommended that derivative is set to OFF to avoid excessive valve activity. Derivative can cause process instability in these processes.
Anti Wind-up
If after fully optimising the tuning, there is an overshoot of the setpoint at start-up or in response to large set­point changes, the reset wind-up inhibit point can be reduced to suspend integral action until the process is closer to setpoint. If set too low control deviation can occur (the process settles, but is offset above or below the setpoint). It this is observed, increase the value until the deviation error is removed.
Too Short: Slow to setpoint or offset
Manual Reset
For proportional only control, after making all other adjustments, if a positive control deviation error exists (process is offset above the setpoint) reduce the man­ual reset until the error is eliminated. If there is a nega­tive error (process is offset below the setpoint) increase manual reset until the error is eliminated.
For PID or PI control, typically set manual reset to ap­proximately 80% of power needed to maintain set­point, but lower values can be used to inhibit start-up overshoot if required.

MODBUS
20 Serial Communications
Supported Protocols
Communication with a Modbus RTU or Modbus TCP master device is possible if the appropriate commu­nications module is fitted in option slot A. An RS485 Module is required for Modbus RTU. An Ethernet Mod­ule is required for Modbus TCP. The instrument can also act as “setpoint master” over RS485 for multi-zone applications. In this mode the unit continuously sends its setpoint value using Modbus broadcast messages. Master mode is not available with Ethernet module.
To protect the EEPROM from excessive write opera­tions, the 6 most recent parameter write requests are held in standard RAM. All data is written to EEPROM at power-down or if another parameter is changed. Avoid continuously changing more than 6 parameters.
All models also have a configuration socket for bench setup via the PC configuration software prior to in­stallation. An RS232 to TTL lead (available from your supplier) is required in order to use this socket. 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.
RS485 Configuration
The RS485 address, bit rate and character format are configured via the front panel from the Comms Con­figuration sub-menu or by using the PC Configurator software.
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 below.
Ethernet Configuration
For Modbus TCP communications (Modbus over Eth­ernet), the Ethernet 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. Refer to the PC Software section of this manual on page 235 for more information about setting the IP ad­dress. The supported data rates 10/100BASE-T (10 or 100 Mbps) are automatically detected.
Link Layer
A query (data request or command) is transmitted from the Modbus Master to the Modbus Slave. The slave instrument assembles the reply to the master. This in­strument is normally a slave device. It can only act as a master when being use as setpoint master controller to broadcast its setpoint to other controllers in a multi­zone application.
SLAVE
MASTER
QUERY
RESPONSE
INSTRUMENT
RS485 Device Addressing
The instrument must be assigned a unique device ad­dress in the range 1 to 255. This address is used to rec­ognize 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 will accept broadcast messages (global queries) using device address 0 no matter what device address is assigned to it. No response messages are returned for globally addressed queries.
Figure 62. Modbus 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.
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.
83
Page 92
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 address, function and data characters.
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.
The standard MODBUS RTU CRC-16 calculation em­ploying the polynomial 216+215+22+1 is used.
