ICoT®

Non-Contact Position Feedback

ROTARY CONTROLSince valve position sensing is performed totally by proximity means, hysteresis within the positioner is non-existent. This feature allows for extremely accuratetracking of the control signal to within 1/10 of 1 mA. A non-contact position sensor, employing Hall Effect magnetic principles for position feedback, is embeddedwithin the ICoT housing. An external magnetic module,attached to the output shaft of the actuator rotates about the Hall Effect sensor. An analog-to-digital convert-er interfaces between the position sensor and a micro-processor while also transmitting the incoming positioncommand (instrument signal) to the microprocessor.Servo circuitry is then utilized for implementation of position control.

LINEAR CONTROLThe ICoT proximity positioner represents a significantdeparture from previous attempts to reliably measurevalve stem position. A static slide-by actuationassembly, attached to the valve stem, is the only“moving part” of the positioner. Position sensing isperformed totally by non-contacting means. Outputupdating takes place twenty times per second. Amicroprocessor implements any alteration required to provide the equivalent of equal percentage, quickopening, or linear valve characteristics.

Output of the processor is the “setpoint” input for theservo amplifier circuitry, while the position sensor provides feedback. The position sensor output signal isalso fed to the analog-to-digital converter permitting awide range of diagnostic information to be generated.MAGNETMAGNET

REMOTE POSITION CONTROLThe ICoT® is the only positioner capable of remotely con-trolling a process valve from up to a distance of fifty feet.Since valve position feedback is accomplished by non-con-tacting means, the ICoT proximity positioner has the uniqueability to be mounted remotely from the device it is control-ling. For applications where a control valve is located ineither a high vibration or extremely corrosive environment,the non-contact position feedback feature allows for isolated placement of the positioner. The position sensoroutput signal is also fed to the analog-to digital converter

housed within the positioner, thereby permitting a widerange of diagnostic information to be generated. Fromthis information, conditions relating to excessive valvefriction and the like, may be delineated. HART® informa-tion consisting of calibration data, current position, and various internal error conditions may be quicklyretrieved due to the accessibility of the positioner.

ICoT® 4100

Electro-Pneumatic Positioner

After more than half a centurythe basic concept of the positionerhas not changed much. However,once in a great while, fundamentalthinking gets a push forward. TheICoT® 4100 represents one ofthose rare times. By creating theindustry’s first electro-pneumaticproximity positioner, the prob-lems associated with conventionalpositioners requiring linkages orlevers for position feedback istotally eliminated. Additionally,the Series 4100 has been engi-neered with ease of maintenanceas a primary design considera-tion. Having only two major components (a transducer andelectronic module) field personnelcan simply replace either modularcomponent for immediate restartof operations. An easily accessible

ICoT® 4100

Electro-Pneumatic Positioner

The ICoT 4200 is optionally avail-able with an integrated 4-20 mAposition feedback transmitter. As opposed to conventional devices,position sensing is performed bynon-contacting means, based uponcharacterization of flux strength asa function of axial position.

ICoT® 4200

Intelligent Positioner with Keypad

Intelligent Proximity Positionerwith Keypad Calibration andOn-Board Sensors

AutoCalThe ICoT® 4200 is equipped witha 3-button keypad interface and a 4-digit, .5” tall LCD that allowsfor automated calibration of thepositioner.

System calibration is performedeasily requiring only minutes toaccomplish. During the calibrationprocess, the microprocessor measures position sensor voltagealong with input setpoint currentand establishes the amount of control signal required to movethe valve to its end limits.

An on-board microprocessor usesthe calibration data to provideaccurate operation over the fullspan of valve travel during normaloperation. The actual valve positionmeasured and the amount of control signal applied at any time is a result of microprocessor interpolation. The interpolationmethod is operator selectable and can be Linear, Quick Opening, or Equal Percentage.

Split range and reverse actingoperation are easily configured.

Local LCD DisplayThe local LCD display provides amultitude of onsite diagnosticinformation. While the valve isbeing controlled by the positioner,and the error signal is NOT zero,the displayed information will alternate between setpoint andposition as percentage. Each valueis displayed for a period of twoseconds. Once the setpoint andvalve position agree to within lessthan ± 0.5%, the display will onlyshow position.

The range of values displayed arefrom 0.0% (fully closed) to 100%(fully open). Displayed resolution is in 0.1% increments, however,internal calculations are maintainedat higher precision.

4-20 mA0-100%

IntegratedPositionTransmitter




A pressure transducer comparesactuator output pressure to theincoming transducer signal for diag-nostic purposes. These two parame-ters are graphically displayed via theHART® interface and provide valuabledata. For example, the relationshipbetween actuator pressure and valvetravel allows for stem friction, springrate, and benchset parameters to becalculated. Excessive stem frictionmay imply the presence of packing orguide bushing problems. Additionally,detection of a non-operational spoolvalve within the ICoT® positioner is also made possible by the pres-sure sensor whose output is utilizedfor comparison with the servo outputcommand to the transducer.

A pressure switch detects abnor-mal internal pressure within thetransducer indicative of a restrictednozzle or punctured diaphragm.

A pressure switch detects low airpressure entering the positioner. Inconjunction with a supply pressureswitch, a determination can be madethat either a restricted filter isresponsible for low air pressureentering the positioner or a bonafidelow supply pressure conditions exists.

Low air supply pressure isdetected by a pressure switchupstream of the internal filter andprovides warning of insufficient powerfor valve stroking.

A 0-100% position feedbacktransmitter is available integratedwithin the electronics of the ICoTpositioner.

Since valve position feedback to theICoT positioner is accomplished bynon-contacting means, the ICoT has the unique ability to be mount-ed remotely (up to a distance of 50feet) from the device it is control-ling. In the event the control valveis located in either a high vibrationor extremely corrosive environment,the non-contact position feedbackfeature allows for isolated place-ment of the positioner.

PID Control A positioner is a servo system that con-tinuously controls the position (output) of a valve in accordance with an externalcontrol signal referred to as setpoint. Ina proportional type system, the setpointis constantly being subtracted from theoutput (position). This signal, resultingfrom the constant subtraction, is termedas error (setpoint - output = error) whichmultiplied by a constant is used to modifythe final output. The magnitude of thisproduct is termed proportional gain or“P” (error x constant = P).

It would seem that the greater onemakes “P” the less the error wouldappear in the final output. Unfortunately,in practice, this does not hold true.

Graph #1 displays the response of apositioner to a sudden change of setpointfor different values of “P”. Setting a smallvalue to “P” results in a final output whichdiffers from the desired output by a largeerror (curve A). Setting a large value to“P” results in an uncontrollable continu-ous oscillation of output termed “UltimateP” (curve C). By interpolating differentvalues of “P”, a value may be obtainedwhich produces a medium error having astable response (curve B). However, theresult of a proportional only type systemstill results in a relatively large error andslow speed of response.

The ICoT smart positioner greatlyenhances the performance of the propor-tional only type system. A derivative (“D”)is added to the servo of the ICoT. “D” isthe derivative of the output with respectto time or the speed at which the valveposition moves multiplied by a constant(speed x constant = “D”). The positioner isnow converted into a “PD” servo type sys-tem. The addition of “D” into the systemincreases speed of response whiledecreasing overshoot. It also allows for “P”to increase above the ultimate proportion-al value, thereby reducing the final error(see graph #2).

In order to decrease the error even further, a third function,”I”, is added to the “PD” servo. The integrator (“I”) slowlydecreases the error when the positionreaches stability. This addition of the “I”function converts the ICoT into a “PID”servo type system.

Autotuning The setting of the proportional, inte-gral, and derivative functions (“PID”),also referred to as “tuning” canbecome quite complex and tedious. Byutilizing the microcontroller within theICoT, Westlock has designed an algo-rithm which automatically tunes allthree parameters. This procedure isreferred to as “autotuning”.

Upon receiving a request for autotune, the positioner enters into a digitalmode and overrides any setpoint command. It initiates the routine bysetting “P”, “I”, and “D” at their lowestvalues. It will then begin to increasethe “P” value until it reaches “UltimateP”. At this instance the CPU records“Ultimate P” and the coinciding periodof oscillation. With the recorded datain memory, the CPU then performs amodified Ziegler-Nichols analysis andcorrespondingly assigns correct valuesto the “P”, “I”, and “D” functions.

HART® Hand-Held TerminalA single 4-20 mA ICoT® positioner with up to two master devices may beconnected to each HART® loop. Theprimary master is generally a manage-ment system or a PC while the second-ary unit can be a hand-held terminal orlaptop computer.

A standard hand-held HART®

Communicator is available for makingfield operations as uniform as possible.Manufactured by Rosemount, the Model275 Smart Family® Interface functions

as a common tool for HART® micro-processor-based field instruments.From any wiring termination point in theloop, the battery-powered Model 275can perform diagnostic, configuration,and interrogation functions. Additionally,while the 275 is offline, configurationdata can be stored for later download-ing to one or more positioners.Simultaneous communication capabili-ties allow the hand-held terminal toreceive data from and send data to thepositioner without disrupting the posi-tioner’s signal from the control room.

Diagnostic andConfiguration Software

ICoT® has developed a SmartPositioner possessing the capabili-ty to predict rather than react tovalve maintenance needs. Withthe ICoT® positioner, operatingpersonnel gain a real-time per-spective on the state of control at the valve, including a view ofoperating integrity and emergingalert conditions. Timely informa-tion about each control valvescondition is quickly made availableto the plant’s production andmaintenance engineers.

THE PRINCIPLE ADVANTAGEOF ONLINE DIAGNOSTICS ISTHE ABILITY TO DETECT DEVI-ATIONS FROM ESTABLISHEDPATTERNS OF BEHAVIOR ASTHEY OCCUR UNDER ACTUALOPERATING CONDITIONS.Control valves are the most mainte-nance intensive components commonlyused in instrumentation and controlsystems. By inclusion of internal parameter sensing within the valvepositioner, forewarning of the need formaintenance is made available with acomfortable degree of lead time.

The ICoT® positioner’s diagnostic com-patibility is based upon observations ofthe following operating parameters:

" Valve position vs. input signal." Actuator pressure vs. valve position." Airset filter outlet pressure." Confirmation of principal operating

pressures within positioner." Pressure generation within packing

gland area.

Online Diagnostics via HART® Link" “Stick-slip” detection." Excessive static position error." Fugitive emissions monitoring." Low air supply pressure." Clogged air supply filter." Restricted transducer nozzle." Transducer diaphragm air leak." Non-functioning spool valve." Calibration error.
