Firmware modification

1 Design and principle ofoperation

The electropneumatic positioner is mountedto pneumatic control valves and is used toassign the valve position (controlledvariable x) to the control signal (referencevariable w). The DC control signal receivedfrom a control unit is compared to the travelor rotational angle of the control valve andissues a signal pressure (output variable y).

The positioner is designed depending on thecorresponding accessories for directattachment to Type 3277 Actuators or forattachment to actuators according toIEC 60534-6 (NAMUR).

Additionally, a coupling wheel included inthe accessories is required to transfer the ro-tary motion for rotary actuators according toVDI/VDE 3845.Springless rotary actuators require an ac-cessory reversing amplifier to permit thepowered operation in either direction.

The positioner basically consists of a travelsensor system that functions proportional tothe resistance, an analog i/p module withdownstream booster as well as the electronicunit with a microcontroller.The positioner is fitted with three binary con-tacts as standard: A fault alarm output isused to indicate a fault to the control stationand two configurable software limit switchesto indicate the valve’s end positions.The position of the valve is transmitted aslinear travel motion or angle of rotation viapick-up lever and travel sensor (2) to an an-alog PD controller (3). Simultaneously, anA/D converter (4) transmits the position ofthe valve to the microcontroller (5). The PD

controller compares this actual position tothe 4 to 20 mA DC control signal (referencevariable) after it has been converted by theA/D converter (4).In case of a system deviation, the operationof the i/p converter (6) is changed so thatthe actuator (1) is filled or vented via thedownstream air capacity booster (7). Thiscauses the closure member of the controlvalve to move to the position determined bythe reference variable.The pneumatic air capacity booster (7) andthe pressure regulator (8) are provided withsupply air. An intermediate flow regulator(9) with fixed settings is used to purge thepositioner and also guarantees trouble-freeoperation of the pneumatic booster. The out-put signal pressure supplied by the boostercan be limited over the software.The volume restriction Q (10) is used to opti-mize the positioner by adapting it to the ac-tuator size.

Serial interface

The positioner is equipped with an interfaceto allow the SAMSON TROVIS-VIEW Con-figuration and Operator Interface softwareto transmit data and parameters over anadapter cable from the RS-232 interface ofa computer to the positioner. Refer to sec-tion 13.

To detect any valve faults at an early stage,the positioner can optionally be equippedwith EXPERT+ valve diagnostics. You can ac-cess the functions provided by EXPERT+

valve diagnostics over TROVIS-VIEW soft-ware and over the DTM file of the device.Refer to Data Sheet T 8388 EN for more de-tails on EXPERT+ valve diagnostics. Instruc-tions on how to operate the software can be

found in the Operating InstructionsEB 8388 EN.

1.1 Additional equipment

As an option, the device can be additionallyequipped with a solenoid valve for forcedventing, an analog position transmitter, aninductive limit switch or an external positionsensor.

Version with solenoid valve

If the operating voltage for the solenoidvalve (12) fails, the supply pressure for thei/p module is vented to the atmosphere. Thepositioner can no longer operate and the

control valve moves to the fail-safe positiondetermined by the actuator, independent ofthe reference variable.

Positioner with position transmitter

The position transmitter (13) is a two-wiretransmitter and issues the travel sensor sig-nal as a 4 to 20 mA signal processed by themicrocontroller.Since this signal is issued independent of thepositioner’s input signal (min. current3.8 mA), the actual travel/angle of rotationis controlled in real-time. Additionally, theposition transmitter provides the possibilityof signaling a positioner fault over a signalcurrent of <2.4 mA or >21.6 mA.

2 Attachment to the controlvalve – Mounting parts andaccessories

The positioner can be attached either di-rectly to a SAMSON Type 3277 Actuator oraccording to IEC 60534-6 (NAMUR) to con-trol valves with cast yokes or rod-type yokesas well as to rotary actuators according toVDI/VDE 3845.

For attachment to the various actuators, cor-responding mounting parts and accessoriesare required. These are listed with their or-der numbers in Tables 1 to 5.

On attaching the positioner, it is importantto observe the assignment between leverand pin position according to the travelslisted in the travel tables.

The tables show the maximum adjustmentrange at the positioner. The travel that canbe implemented at the valve is restricted bythe pin position used and additionally by theactuator spring compression required.The positioner is standard equipped with thelever M (pin position 35).

Note!If the standard mounted lever M (pin posi-tion 35) is replaced, the newly mounted le-ver must be moved once all the way as faras it will go in both directions to adapt it tothe internal measuring lever.

3.1 Pneumatic connections

Caution!The threads in the positioner housing are notdesigned for direct air connection!

The screw glands must be screwed into theconnecting plate, the pressure gauge mount-ing block or the connection block from theaccessories. The air connections are option-ally designed as a bore with ¼ NPT or G ¼thread.The customary fittings for metal and copperpipes or plastic hoses can be used.

Note!The supply air must be dry and free from oiland dust. The maintenance instructions forupstream pressure reducing stations must beobserved.Blow through all air tubes and hoses thor-oughly prior to connecting them.

If the positioner is attached directly to theType 3277 Actuator, the connection of thepositioner's output pressure to the actuatoris fixed. For attachment according toIEC 60534-6 (NAMUR), the signal pressurecan be routed to either the top or bottom di-aphragm chamber of the actuator, depend-ing on the actuator's fail-safe action "Actua-tor stem extends" or "Actuator stem re-tracts".For rotary actuators, the manufacturer'sspecifications for connection apply.

3.1.1 Signal pressure gauges

To monitor the supply air (Supply) and sig-nal pressure (Output), we recommend thatpressure gauges be attached (see accesso-ries in Tables 1 to 4).

3.1.2 Supply pressure

The required supply air pressure dependson the bench range and the actuator's oper-ating direction (fail-safe action).The bench range is registered on the name-plate either as spring range or signal pres-sure range depending on the actuator. dieThe direction of action is marked FA or FE,or by a symbol.

Actuator stem extends FA (Air to openATO)

Fail-safe position "Valve Closed"(for globe and angle valves):

Required supply pressure = Upper benchrange value + 0.2 bar, minimum 1.4 bar.

4. Position control valve by turning thebutton several times until pressure buildsup, and the control valve moves to its fi-nal positions so that the travel/angle ofrotation can be checked.The permissible range has been ex-ceeded when the displayed angle ishigher than 30°, and the outer right orleft bar graph element blinks.If this is the case, it is absolutely neces-sary to check lever and pin position asdescribed in section 2.

Note!If the selected pin position is smaller than in-tended for the respective travel range, thepositioner switches to the SAFE mode, thevalve moves to the fail-safe position (seesection 4.3.2 on page 42).

5. Initialize positioner as described in sec-tion 5.5.

44 EB 8384-2 EN


Simplified start-up!For most applications, the positioner with its default settings is ready for operation,provided it has been properly attached.After the fail-safe position and the volume restriction have been set, the positioner onlyneeds to be initialized by pressing the INIT key.

Caution!Prior to starting the initialization procedure, check the maximum permissible supplypressure of the control valve to prevent the valve from being damaged. On initialization,the positioner supplies the maximum available supply pressure. If necessary, restrict thesignal pressure by using a pressure reducing valve upstream of the control valve.Initialization is run in default mode MAX (section 5.5.1). During this process, thepositioner adapts itself optimally to the maximum travel/angle of rotation range.The only parameter that must be checked is the direction of action, i.e. whether the defaultsetting (Code 7 to = increasing/increasing) matches the application or whether itmust be changed.The initialization modes described in following serve to individually adapt and optimizethe positioner to the way it is attached to the valve.

5.5 Initialization

During initialization the positioner adapts it-self optimally to the friction conditions andthe signal pressure demand of the controlvalve.The type and extent of self-adaptation de-pends on the set initialization mode (seesection 5.5.1).MAX is the default setting for initializationbased on the maximum nominal range.

If configuration is enabled via Code 3, Code6 can be used to change to other initializa-tion modes.

If the positioner has been initialized once al-ready, it will automatically go to the operat-ing mode used last after the electrical refer-ence variable is applied, Code 0 appearson the display.If the positioner has not yet been initialized,the fault symbol appears on the displayand the hand symbol blinks.

Note!Every time you re-initialize the positioner, itshould be reset to its basic setting includingthe default values. Refer to section 5.8 onpage 54.

Start the initialization process by press-ing the INIT key with a suitable tool.

The time required for an initialization pro-cess depends on the transit time of the actu-ator and take several minutes.Positioners with EXPERT+ diagnostic func-tions start plotting the reference graphs after

the initialization process has been com-pleted. See note at the end of this section.

Warning!During initialization, the controlvalve moves through its entiretravel/angle of rotation range.Therefore, do not start initializationwhile a process is running, but onlyduring start-up, when all shut-offvalves are closed.Note! The initialization procedurecan be canceled while running bypressing . StOP appears threeseconds long and the positioner thenmoves to the fail-safe position.

A malfunctioning leads to the process beingcanceled automatically. The initialization er-ror appears on the display according tohow it has been classified by the condensedstatus. See section 5.6 on page 53.

If the slide switch is set to AIR TO CLOSE,the positioner automatically switches to thedirection of action increasing/decreasing() on successful completion of initializa-tion. This results in the following assignmentbetween reference variable and valve posi-tion:

The tight-closing function is activated.Set Code 15 (final position w>) to 99 % forthree-way valves.Further settings relevant for the valve can beentered subsequently.

Note!Positioner with integrated EXPERT+ diagnos-tics automatically start to plot the referencegraphs (drive signal Y d1 and hysteresis d2)after initialization has been completed. TESTd1 and d2 appear on the display in an al-ternating sequence.An unsuccessful plotting of the referencegraphs are indicated on the display byCode 81 (see error code list).After the initialization has been successfullycompleted, the positioner still works prop-erly, even though the reference graph plot-ting has not been completed successfully.

The reference graphs are required for theextended diagnostic functions of EXPERT+.

5.5.1 Initialization modes

After enabling configuration with Code 3and accessing Code 6, you can choose oneof the initialization modes MAX, NOM,MAN or SUb to start initialization.ZP, the zero calibration is described in sec-tion 5.7 on page 54.

MAX – Initialization based on maximumrange

Initialization mode for simplified start-up forvalves with two clearly defined mechanicaltravel stops, e.g. three-way valves.

The positioner determines travel/angle ofrotation of the closing member from theCLOSED position to the opposite side andadopts this travel/angle of rotation as theoperating range from 0 to 100 %.

The initialization procedure maytake several minutes, depending onthe actuator size, as the valve movesthrough its entire travel/angle of ro-tation range.

Positioners with EXPERT+ diagnostic func-tions automatically start plotting the refer-ence graphs after the initialization processhas been completed. See section 5.5.

Note!For MAX initialization, the positioner cannotindicate nominal travel/angle of rotation inmm/°, Code 5 remains disabled.In addition, the lower (Code 8) and the up-per (Code 9) x-range value can only be dis-played and modified in %.During MAX initialization, an increased sys-tem deviation (undefined final position of theactuator) in the upper control range may oc-cur with some control valves due to thepneumatic actuator design.

If you want the display to indicate mm/°,proceed as follows after configuration hasbeen enabled:


turn → Select pin position entered dur-ing installation, press .

If you now switch to Code 5, the nominalrange appears in mm/°.The lower and upper x-range values forCode 8 and 9 are displayed in mm/° andcan be adapted accordingly.

NOM – Initialization based on nominalrange

Initialization mode for globe valves, espe-cially for valves with maximum ranges thatare clearly greater than the required nomi-nal range.For this initialization mode, the followingparameters must be entered: pin position(Code 4), nominal travel/angle (Code 5)and, if required, the direction of action(Code 7).

The calibrated sensor enables the effectivevalve travel to be preset very accurately.

EB 8384-2 EN 47


During the initialization procedure, thepositioner checks whether the control valvecan move through the indicated nominalrange (travel or angle) without collision.In case of a positive result, the indicatednominal range is adopted with the limits oflower x-range and upper x-range values asthe operating range.

Note!The maximum possible travel must alwaysbe greater than the nominal travel entered.If this is not the case, the initialization iscanceled (error indication Code 52) be-cause the nominal travel is not achieved.

SUb

(substitute configuration, without initializa-tion)

This initialization mode is an emergencymode. The positioner parameters are esti-mated and not determined by an initializa-tion procedure, so that a high stationary ac-curacy cannot be expected.You should always select a different initial-ization mode if the plant allows it.

The initialization mode SUb is used to re-place a positioner while the process is in op-eration. For this purpose, the control valve isusually fixed mechanically in a certain posi-tion, or pneumatically by means of a pres-sure signal which is routed to the actuatorexternally. The blocking position ensuresthat the plant continues to operate with thisvalve position.The spare positioner should not be initial-ized. If necessary, reset the spare positionerusing Code 36.

After the old positioner has been replacedwith a new one, the following parametersmust be entered: pin position (Code 4),nominal range (Code 5), direction of action(Code 7) and closing direction (Code 34).The default travel limit of 100 % (Code 11)must be disabled with OFF.In addition, the blocking position (Code 35)must be adjusted with the button so thatit matches the position of the previouslyblocked valve.The parameters KP (Code 17), TV (Code 18)and the pressure limit (Code 16) should re-main set to their default values. If the config-uration data of the new positioner areknown, it is recommended to accept its KPand TV values.

After setting the AIR TO OPEN/CLOSEswitch for the fail-safe position, setting thevolume restriction and pressing the INIT key,the positioner calculates its configurationdata on the basis of the blocking positionand the closing direction as well as the otherentered data.The positioner switches to manual operation,subsequently the blocking position should becanceled as described on page 52.

5.9 Start-up via local interface(SSP)

The positioner must be supplied with at least4 mA.The positioner can be connected directly tothe PC via the local serial interface and theserial interface adapter.

Use the TROVIS-VIEW software with 3730-2device module installed. Refer to section 13for more details.

For start-up and settings, proceed as de-scribed in section 5, 5.1 to 5.3 and thenproceed as described in section 13.

Note!Depending on the firmware installed in thepositioner, a certain minimum version of theTROVIS-VIEW device module is required forcommunication.If you have already installed the software,you can download updates atwww.samson.de (Support & Downloads -TROVIS VIEW Updates).

6 Status and diagnostic alarms

The Type 3730-2 Positioner contains an in-tegrated diagnostic approach to generateclassified status and diagnostic alarms.

There are two different on-board diagnosticsavailable: the standard integrated diagnos-tics (EXPERT) and the optional extendedEXPERT+ diagnostics.

6.1 Standard EXPERT diagnostics

The standard EXPERT diagnostics providesinformation about positioner states such asoperating hours counter, process monitor-ing, number of zero calibrations andinitializations, total valve travel, tempera-ture, initialization diagnostics, zero/controlloop errors, logging of the last 30 alarms,etc.

In addition, the standard EXPERT diagnosticsgenerates diagnostic and status alarmswhich allow faults to be pinpointed quicklywhen a fault occurs.

Alarms are classified in the following maingroups:

Status

Operation

Hardware

Initialization

Data memory

Temperature

Status and diagnostic alarms

6.2 Extended EXPERT+ diagnos-tics

In addition to the standard EXPERT diagnos-tic features, the optional EXPERT+ extendeddiagnostics provides the following onlineand offline test functions which enablesignificant statements on the condition of theentire control valve.

Online test functions (monitoring functions)

Data logger

Histogram

Cycle counter

Valve end position trend

Y = f (X) diagram (drive signal)

Hysteresis test

Offline test functions (manual functions)

Y = f (X) diagram over the entire valvetravel range

Hysteresis test over the entire valve travelrange

Static characteristic

Step response test

The diagnostic tests are completely inte-grated in the positioner. Further statusalarms are generated from the extensive in-formation gained in the diagnostic tests ofEXPERT+ which provide the user with infor-mation covering the whole control valve.The required reference curves are automati-cally plotted after initialization and saved inthe positioner if EXPERT+ is activated.The optional diagnostic functions providedby EXPERT+ can be selected when ordering

the positioner. Additionally, it is possible toactivate EXPERT+ at a later point in time inan existing positioner.For this purpose, an activation code can beordered, specifying the serial number of thepositioner.

6.3 Classification of the statusalarms and condensed status

The alarms are assigned a classificationstatus in the positioner. The following statesare differentiated between:

FailureThe positioner cannot perform its controltask due to a functional fault in the device orin one of its peripherals or an initializationhas not yet been successfully completed.

Maintenance demandThe positioner still performs its control task(with restrictions). A maintenance demandor above average wear has been deter-mined. The wear tolerance will soon be ex-hausted or is reducing at a faster rate thanexpected. Maintenance is necessary in themedium term.

Maintenance requirementThe positioner still performs its control task(with restrictions). A maintenance demandor above average wear has been deter-mined. The wear tolerance will soon be ex-hausted or is reducing at a faster rate thanexpected. Maintenance is necessary in theshort term.

Function checkTest or calibration procedures are beingperformed. The positioner is temporarily un-able to perform its control task until thisprocedure is completed.

56 EB 8384-2 EN


Classification process in the positionerAn alarm is assigned to one of followingclassified states in the table:

Condensed status

To provide a better overview, the state of thepositioner is summarized in a condensedstatus which is made up from a summary ofall classified positioner alarms.

If an event is classified as “No alarm”, thisevent does not have any affect on the con-densed status of the positioner.

The condensed status is displayed in the en-gineering tool as well as on the positionerdisplay as in the following table:

Status modification

The classification of the status alarms can bechanged as required.They can be modified using TROVIS-VIEWsoftware over the local SSP interface.

Note!All additional alarms generated by EXPERT+

have the status “No alarm” by default.

Logging and displaying diagnosticfunctions/alarms

The last 30 alarms are logged in thepositioner. However, it is important to notethat the same alarm is only logged oncewhen it first occurs.The alarms and the condensed states ap-pear on the display as described in the codelist (section 12).In addition, the diagnostic parameters areissued over the communication interface ofthe positioner.

The diagnostic functions can easily bedisplayed and configured using theTROVIS-VIEW software connected over thelocal interface (SSP).

Setting the switching point:

Important!During adjustment or testing, the switchingpoint must always be approached frommid-position (50 %).

To ensure safe switching under any ambientconditions, the switching point should beadjusted to a value of approx. 5 % beforethe mechanical stop (OPEN – CLOSED).

For CLOSED position:

1. Initialize positioner.2. Use the MAN function to move the

positioner to 5 % (see LC display).3. Adjust the tag using the yellow adjust-

ment screw (2) until the tag enters orleaves the field and the switching ampli-fier responds. You can measure theswitching voltage as an indicator.

Contact function:Tag leaving the field > contact is made.Tag entering the field > contact is opened.

For OPEN position:

1. Initialize positioner.2. Use the MAN function to move the

positioner to 95 % (see LC display).3. Adjust the tag (1) using the yellow ad-

justment screw (2) until the tag enters orleaves the field of the proximity switch(3).You can measure the switching voltageas an indicator.

10 Maintenance

The positioner does not require any mainte-nance.

There are filters with a 100 µm mesh size inthe pneumatic connections for supply andoutput which can be removed and cleaned,if required.

The maintenance instructions of any up-stream supply air pressure reducing stationsmust be observed.

11 Servicing explosion-protecteddevices

If a part of the positioner on which the ex-plosion protection is based needs to be ser-viced, the positioner must not be put backinto operation until an expert has inspectedthe device according to explosion protectionrequirements, has issued a certificate statingthis or given the device a mark of confor-mity.

Inspection by an expert is not required if themanufacturer performs a routine check onthe device prior to putting it back into oper-ation. The passing of the routine check mustbe documented by attaching a mark of con-formity to the device.

Explosion-protected components may onlybe replaced by original, checked compo-nents from the manufacturer.

Devices that have already been used outsideof hazardous areas and are intended foruse in hazardous areas in future must com-ply with the safety demands placed on re-paired devices. Prior to operation, they mustbe tested according to the specificationsstipulated for "Repairing explosion-pro-tected devices".

Error codes – Remedy Condensed status alarm active, when prompted, Err appears.

Initialization error(indicated on the display by the condensed status with the corresponding classification)

50 x < range The value supplied by the measuring signal is either too high ortoo low, the measuring sensor is close to its mechanical limit.• Pin positioned incorrectly.• Bracket slipped in case of NAMUR attachment or positioner is

not central.• Follower plate incorrectly attached.

Remedy Check attachment and pin position, set operating mode fromSAFE to MAN and re-initialize the positioner.

51 ∆x > range The measuring span of the sensor is too low.• Pin positioned incorrectly.• Wrong lever.A rotational angle smaller than 11° at the positioner shaft createsjust an alarm. An angle below 6° leads to the initialization beingcanceled.

Remedy Check attachment and re-initialize the positioner.

52 Attachment • Positioner attachment incorrect.• Nominal travel/angle (Code 5) could not be achieved on

initialization under NOM or SUb (no tolerance downwardspermissible)

• Mechanical or pneumatic error, e.g. wrong lever selected orsupply pressure too low to move to the required position orpneumatic fault

Remedy Check attachment and supply pressure. Re-initialize thepositioner.Under certain circumstances, it may be possible to check themaximum travel/angle by entering the actual pin position andthen performing an initialization under MAX.After initialization has been completed, the Code 5 indicates themaximum achieved travel or angle.

53 Init time > The initialization routine lasts too long. The positioner returns toits previous operating mode.• No pressure on the supply line or there is a leak.• Supply air failure during initialization.

Remedy Check attachment and supply pressure.Re-initialize the positioner.

EB 8384-2 EN 75

Code list

54 Init – Solenoid valve 1) A solenoid valve is installed (Code 45 = YES) and wasnot or not properly connected so that an actuator pressurecould not be built up. The message appears when youattempt to initialize the positioner.

2) If you attempt to initialize the device from the fail-safeposition (SAFE).

Remedy Re. 1) Check connection and supply voltage of the solenoidvalve.

Re. 2) Set the MAN operating mode over Code 0. Then initializethe positioner.

55 Transit time < The actuator transit times determined during the initialization areso short that the positioner cannot adapt itself optimally.

Remedy Check the volume restriction setting as described in section 5.2,re-initialize the positioner.

56 Pin pos. Initialization was canceled because you are required to enter thepin position for the selected initialization modes NOM and SUb.

Remedy Enter pin position over Code 4 and nominal travel/angle overCode 5. Re-initialize the positioner.

Operational error (indicated on the display by the condensed status with the correspondingclassification)

57 Control loop

Additional message at the faultalarm contact!

Control loop fault, the control valve does not react within the tol-erable times of the controlled variable (tolerance band alarmCode 19).• Actuator mechanically blocked.• Attachment of the positioner subsequently postponed.• Supply pressure not sufficient.

Remedy Check attachment.

58 Zero point Zero point incorrect. Error may arise when the mounting posi-tion/linkage of the positioner moves or when the valve seat trimis worn, especially with soft-sealed plugs.

Remedy Check valve and mounting of the positioner. If OK, perform azero calibration over Code 6 (see section 5.7 on page 54).

59 Autocorrection Should an error occur in the data range of the positioner, theself-monitoring function recognizes it and automatically correctsit.

Remedy Automatic

76 EB 8384-2 EN

60 Fatal error


An error was detected in the data relevant for safety,autocorrection is not possible. This may be due to EMC distur-bances.The control valve is moved to the fail-safe position.

Remedy Reset over Code 36.Re-initialize the positioner.

Hardware error (indicated on the display by the condensed status with the corresponding classification)

62 x signal


Determination of the measured value for the actuator has failed.Conductive plastic element is defective.The positioner continues to run in emergency mode, but shouldbe replaced as soon as possible.The emergency mode on the display is indicated by a blinkingcontrol symbol and 4 dashes instead of the position indication.Note on the control:If the measuring system has failed, the positioner is still in a reli-able state. The positioner switches to emergency mode where theposition cannot be accurately controlled anymore. However, thepositioner continues operation according to its reference variablesignal so that the process remains in a safe state.

Remedy Return the positioner to SAMSON AG for repair.

63 w too small The reference variable is much smaller than 4 mA (0 %); occurs ifthe power source that drives the positioner does not comply withthe standard.This state is indicated on the positioner display by a blinkingLOW.

Remedy Check reference variable.If necessary, limit the current source downwards so that no valuesbelow 4 mA can be issued.

64 i/p converter (y) The circuit of the i/p converter has been interrupted.

Remedy Cannot be remedied.Return the positioner to SAMSON AG for repair.

75 Parameter info Error in the parameter info which is not critical for the control.

Remedy Confirm error.Check and, if necessary, reset required parameters.

76 No emergency mode The travel measuring system of the positioner has a self-moni-toring function (see Code 62).A controlled emergency mode is not available on certain actua-tors, such as double-acting actuators. For this reason, thepositioner moves into the fail-safe position when a measuringerror occurs. During the initialization, the positioner checkswhether the actuator has such a function or not.

Remedy Merely information, confirm, if necessary.No further action necessary.

77 Program loading errorAdditional message at the faultalarm contact!

When the device starts operation for the first time after the inputsignal has been applied, it carries out a self-test (tEStinG runsacross the display).If the device loads a program that does not correspond to that ofthe positioner, the valve is moved into the fail-safe position. It isnot possible to make the valve leave this fail-safe position againby operating the positioner.

Remedy Interrupt current supply and restart positioner. Otherwise, returnthe positioner to SAMSON AG for repair.

78 Options parameter Errors in options parameters, e.g. due to EMC disturbances.

13 Setting with TROVIS-VIEW software – Parameter list

13.1 General

A CD-ROM containing the program for installing the TROVIS-VIEW Configuration and Op-erator Interface is provided by SAMSON.

Insert the installation CD-ROM to start the installation program. Once inserted, the CD-ROMusually starts the installation program automatically depending on the configuration of theoperating system.If the program does not start automatically, double-click setup.exe in the root directory of theCD-ROM in order to install TROVIS-VIEW.Follow the on-screen prompts and instructions of the installation program.

The system requirements are specified in the readme.txt file in the root directory of theCD-ROM.

The TROVIS-VIEW Operator Interface can be used for different SAMSON devices. Note thatthe installation program also offers you the option of installing a demo module. To use thesoftware without restrictions, the software needs to be activated as described below:

After installation, a dialog box will appear, prompting you to enter the CD key, which youwill find on the cover of the original CD-ROM. Once you have entered the correct CD keyand initiated the activation process, a request code will be automatically generated. The Ac-tivation dialog box will come up displaying the generated request code and an Internet linkto SAMSON’s activation server where a unique activation code will then be generated anddisplayed. Enter this activation code into TROVIS-VIEW’s Activation dialog box. The soft-ware is now ready for use without any restrictions in the purchased scope.

To enable communication with the PC, connect the serial interface to the serial interface(5-pole female socket) of the positioner using a SAMSON connecting cable with serial inter-face adapter (order no. 1400-7700).

The positioner settings configured in TROVIS-VIEW can be directly transferred over theSAMSON connecting cable to the positioner on site. This online connection enables you toread any entered settings as well as providing a diagnostic function.
