General safety instructions
The positioner may only be assembled, started up or operated by trained
4
and experienced personnel familiar with the product. According to these mounting and operating instructions, trained personnel is referred to as individuals who are able to judge the work they are assigned to and recognize possible dangers due to their specialized training, their knowledge and experience as well as their knowledge of the relevant standards. Explosion-protected versions of this positioner may only be operated by
4
personnel who have undergone special training or instructions or who are authorized to work on explosion-protected devices in hazardous areas. Refer to section 11 on Servicing explosion-protected versions. Any hazards that could be caused by the process medium, the operating
4
pressure, the signal pressure or by moving parts of the control valve are to be prevented by means of the appropriate measures. If inadmissible motions or forces are produced in the actuator as a result of
4
the supply pressure level, it must be restricted by means of a suitable supply pressure reducing station. Do not operate the positioner with the back of it/exhaust air opening facing upwards. Never seal the exhaust air opening when the positioner is mounted on site. Proper shipping and appropriate storage are assumed.

Design and principle of operation
1 Design and principle of
operation
The digital positioner receives the reference variable (reference variable w) transmitted cyclically over FOUNDATION and compares it to the travel or rotational angle of the control valve (controlled vari­able x). The positioner issues a pneumatic signal pressure (output variable y) to correct the valve position.
The Type 3730-5 Positioner communicates with field devices, logic solvers, and process control system over FOUNDATION Fieldbus protocol. An integrated PID function block permits the required process variable to be controlled directly in the field.
The positioner is designed depending on the corresponding accessories for direct attach­ment to SAMSON Type 3277 Actuators or for attachment to actuators according to IEC 60534-6 (NAMUR).
TM
Fieldbus
TM
Simultaneously, an A/D converter (4) trans­mits the position of the valve to the microcontroller (5). The PD compares this actual position to the FOUNDATION
TM
Fieldbus reference variable transmitted cycli­cally by the control equipment. In case of a system deviation, the operation of the i/p converter (6) is changed so that the actuator (1) is filled or vented via the downstream air capacity booster (7). This causes the closure member of the control valve to move to the position determined by the reference variable.
The pneumatic air capacity booster (7) and the pressure regulator (8) are provided with supply air. An intermediate flow regulator (9) with fixed settings is used to purge the positioner and also guarantees trouble-free operation of the pneumatic booster. The out­put signal pressure supplied by the booster can be limited over the software. The volume restriction Q (10) is used to opti­mize the positioner.
Additionally, a coupling wheel included in the accessories is required to transfer the ro­tary motion for rotary actuators according to VDI/VDE 3845. Springless rotary actuators require a revers­ing amplifier to allow the positioner to oper­ate in either direction.
The positioner basically consists of a travel sensor system that functions proportional to the resistance, an analog i/p module with downstream booster as well as the electronic unit with a microcontroller. The position of the valve is transmitted as an angle of rotation to the travel sensor (2) and to an analog PD controller (3).
6 EB 8384-5 EN
1.1 Additional equipment
Version with solenoid valve
If the operating voltage for the solenoid valve (12) fails, the supply pressure for the i/p module is vented to the atmosphere. The positioner can no longer operate and the control valve moves to the fail-safe position determined by the actuator, independent of the reference variable.

Design and principle of operation
Version with inductive limit switch
The rotary shaft of the positioner carries an adjustable tag which actuates the installed proximity switch.
Version with binary contact
All positioners are fitted with a binary input for DC voltage signals over which process information over FOUNDATION
TM
Fieldbus can be issued. Another optional binary input is an active input powered by the positioner to connect a floating contact. Its switching condition can also be issued over FOUNDATION
TM
Fieldbus.

Depending on the type of positioner attach­ment, the signal pressure is routed either left or right of the yoke through a bore to the actuator diaphragm. Depending on the fail-safe action of the actuator "Actuator stem extends" or "Actuator stem retracts" (valve closes or opens if the supply air fails), the switchover plate (9) must first be at­tached to the actuator yoke. Align the switchover plate with the corresponding symbol for left or right attachment according to the marking (view looking onto the switchover plate).
1. Mount connecting plate (6) or pressure
gauge bracket (7) with pressure gauges onto the positioner, making sure both seal rings (6.1) are seated properly.
2. Remove vent plug (4) on the back of the
positioner and close the signal pressure output "Output 38" on the connecting plate (6) or on the pressure gauge bracket (7) with the stopper (5) included in the accessories.
3. Place follower clamp (3) on the actuator
stem, align and screw tight so that the mounting screw is located in the groove of the actuator stem.
4. Mount cover plate (10) with narrow side
of the cut-out opening (Fig. 3, left) point-
2
ing towards the signal pressure connec­tion. Make sure that the bonded gasket (14) points towards the actuator yoke.
5. 15 mm travel: Keep the follower pin (2) at lever M (1) on the back of the positioner in the pin position 35 (deliv­ered state).

2.4 Attachment to rotary actuators
The positioner is mounted to the rotary actu­ator using two pairs of double brackets.
Refer to Table 4 on page 13 for the required mounting parts as well as the accessories with their order numbers.
Prior to the attachment of the positioner to the SAMSON Type 3278 Rotary Actuator, you have to mount the associated adapter (5) to the free end of the rotary actuator shaft.
Note!
During the installation of the positioner as described below, it is imperative that the ac­tuator's direction of rotation be observed.
1. Place follower clamp (3) on the slotted
actuator shaft or the adapter (5).
2. Place coupling wheel (4) with flat side
facing the actuator on the follower clamp (3). Refer to Fig. 8 to align slot so that it matches the direction of rotation when the valve is in its closed position.
3. Screw coupling wheel and follower
clamp tightly onto the actuator shaft us­ing screw (4.1) and disk spring (4.2).
4. Screw the bottom pair of brackets (10.1)
with the bends pointing either to the in­side or to the outside (depending on the actuator size) to the actuator case. Posi­tion top pair of brackets (10) and screw tight.
5. Mount connecting plate (6) or pressure
gauge bracket (7) with pressure gauges
to the positioner, making sure both O-rings are seated properly. For double-acting, springless rotary ac­tuators, a reversing amplifier is required to attach the positioner to the actuator, see section 2.5.
6. Unscrew the standard follower pin (2)
from the positioner's lever M (1). Use the metal follower pin (Ø5) included in the mounting kit and screw tight into the bore for pin position 90°.
7. Place positioner on the top pair of brackets (10) and screw tight. Con­sidering the actuator's direction of rota­tion, adjust lever (1) so that it engages in the slot of the coupling wheel (4) with its follower pin (see Fig. 8). It must be guar­anteed that the lever (1) is parallel to the long side of the positioner when the ac­tuator is at half its angle of rotation.
8. Stick scale plate (4.3) on the coupling wheel so that the arrow tip indicates the closed position, and it can be easily read when the valve is installed.

3.1 Pneumatic connections
Caution!
The threads in the positioner housing are not designed for direct air connection!
The screw glands must be screwed into the connecting plate, the pressure gauge mount­ing block or the connection block from the accessories. The air connections are option­ally designed as a bore with ¼ NPT or G ¼ thread. The customary fittings for metal and copper pipes or plastic hoses can be used.
Note!
The supply air must be dry and free from oil and dust. The maintenance instructions for upstream pressure reducing stations must be observed. Blow through all air tubes and hoses thor­oughly prior to connecting them.
3.1.1 Signal pressure gauges
To monitor the supply air (Supply) and sig­nal pressure (Output), we recommend that pressure gauges be attached (see accesso­ries in Tables 1 to 5).
3.1.2 Supply pressure
The required supply air pressure depends on the bench range and the actuator's oper­ating direction (fail-safe action). The bench range is registered on the name­plate either as spring range or signal pres­sure range depending on the actuator. die The direction of action is marked FA or FE, or by a symbol.
Actuator stem extends FA (Air to open ATO)
Fail-safe position "Valve Closed" (for globe and angle valves):
Required supply pressure = Upper bench range value + 0.2 bar, minimum 1.4 bar.
Actuator stem retracts FE (Air to close ATC)
If the positioner is attached directly to the Type 3277 Actuator, the connection of the positioner's output pressure to the actuator is fixed. For attachment according to IEC 60534-6 (NAMUR), the signal pressure can be routed to either the top or bottom di­aphragm chamber of the actuator, depend­ing on the actuator's fail-safe action "Actua­tor stem extends" or "Actuator stem re­tracts". For rotary actuators, the manufacturer's specifications for connection apply.

3.2 Electrical connections
For electrical installation, you are re­quired to observe the relevant electrotechnical regulations and the accident prevention regulations that apply in the country of use. In Ger­many, these are the VDE regulations and the accident prevention regula­tions of the employers' liability insur-
ance association. The following standards apply for assembly and installation in hazardous areas: EN 60079-14: 2003 (VDE 0165 Part 1/
8.98) "Electrical apparatus for explosive gas atmospheres" and EN 50281-1-2: 1999 (VDE 0165 Part 2/11.99) "Electrical appa­ratus for use in the presence of combustible dust".
For the interconnection of intrinsically safe electrical equipment, the permissible maxi­mum values specified in the EC type exami­nation certificate apply (U or P0; Cior C0, and Lior L0).
The following applies for equipment with type of protection EEx nA (non-sparking ap­paratus) according to the standard EN 50021 (1999): Connecting, interrupting, or switching circuits while energized is only al­lowed during installation, maintenance or repair work.
The following applies for equipment con­nected to energy-limited circuits with type of protection EEx nL (energy-limited apparatus) according to the standard EN 50021 (1999): This type of equipment may be switched under normal operating conditions.
or U0; Iior I0; P

For the interconnection of equipment to en­ergy-limited circuits with type of protection EEx nL IIC, the permissible maximum values specified in the statement of conformity or the addenda to the statement of conformity apply.
Caution!
The terminal assignment specified in the cer­tificate must be adhered to. Reversing the assignment of the electrical terminals may cause the explosion protection to become in­effective! Do not tamper with enameled screws inside or on the housing.
Note on the selection of cables and wires:
To install intrinsically safe circuits, observe section 12 of the standard EN 60079-14: 2003 (VDE 0165 Part 1). To run multi-core cables or lines with more than one intrinsi­cally safe circuit, section 12.2.2.7 of this standard applies. An additional cable gland can be installed when connecting the device over two sepa­rate cables. Cable entries left unused must be sealed with blanking plugs. Devices used at ambient temperatures down to –20 °C must have metal cable entries.
Cable entry
Cable entries with M20x1.5 cable gland, clamping area 6 to 16 mm. There is a second M20x1.5 entry in the housing which can be used to install an additional connection, if required. The screw terminals are designed for 0.2 to
2.5 mm wire cross sections and for a tightening torque of 0.5 Nm.

Note!
To connect the limit switch, binary inputs, and forced venting, an additional cable gland that needs to be fitted in place of the existing blanking plug is necessary. Open cable glands are not permissible as the degree of protection IP 65 only applies when the positioner housing is sealed.
Limit switch
For operation of the limit switches, switching amplifiers have to be connected in the out­put circuit. Their function is to control the limit values of the control circuit according to EN 60947-5-6, thus ensuring operational reliability of the positioner. If the positioner is installed in hazardous areas, the relevant regulations must be observed.
Note!
If there is no voltage connected for the sole­noid valve at terminals +81 and –82 or when the voltage signal is interrupted, the positioner vents the actuator and does not respond to the reference variable. Observe the switching thresholds specified in the technical data.
3.2.1 Establishing communication
The communication structure between the controller, logic solvers (PLC) or automation system, or between a PC or work station and the positioner(s) is implemented to con­form with EN 61158-2.
Binary input 1
An active contact can be operated at binary input 1. The positioner can report the switching state over the bus protocol.
Binary input 2
A passive, floating contact can be operated at binary input 2. The positioner can report the switching state over the bus protocol.
Solenoid valve (forced venting function)
For positioners fitted with the optional sole­noid valve for the forced venting function, a voltage of 24 V DC must be connected to the relevant terminals +81 and –82.

Displays
Symbols appear on the LC display that are assigned to parameters, codes, and func­tions. The bar graph in the operating modes Man­ual and Automatic indicates the sys­tem deviation that depends on the sign (+/–) and the value. One bar graph element ap­pears per 1 % system deviation.
If the device has not yet been initialized (see section 4.3.1), the lever position in degrees in relation to the longitudinal axis is indi­cated instead of the system deviation. One bar graph element corresponds to approxi­mately a 5° angle of rotation.
If the fifth element blinks (value displayed > 30°), the permissible angle of rotation has been exceeded. Lever and pin position must be checked.

Warning!
During the initialization, the control valve moves through its entire travel/angle of rotation range. Therefore, do not start initialization while a process is running, but only during start-up, when all shut-off valves are closed.
Note!
The initialization procedure can be interrupted while running by press­ing . StOP appears three seconds long and the positioner then moves to the fail-safe position. The fail-safe position can be can­celed again over Code 0.

NOM – Initialization based on nominal range
Initialization mode for globe valves, espe­cially for valves with maximum ranges that are clearly greater than the required nomi­nal range. For this initialization mode, the following parameters must be entered: pin position (Co
de 4
) and nominal travel/angle
(Code
5
).
The calibrated sensor enables the effective valve travel to be preset very accurately. During the initialization procedure, the positioner checks whether the control valve can move through the indicated nominal range (travel or angle) without collision. In case of a positive result, the indicated nominal range is adopted with the limits of lower x-range and upper x-range values as the operating range.
Note!
The maximum possible travel must always be greater than the nominal travel entered. If this is not the case, the initialization is in­terrupted (error indication Code 52) be­cause the nominal travel is not achieved.

A complete initialization procedure takes several minutes and requires the valve to move through its entire travel range several times. In the event a positioner must be re­placed while the plant is running, this mode allows the replacement to be performed with the minimum amount of disruption to the plant.
This initialization mode is an emergency mode. The positioner parameters are esti­mated and not determined by an initializa­tion procedure, so that a high stationary ac­curacy cannot be expected. You should always select a different initial­ization mode if the plant allows it.

Status and diagnostic alarms
5.10 Start-up via local interface (SSP)
The positioner can either be commissioned, configured, and operated on site, using the Fieldbus configuration or operating system, or TROVIS-VIEW operator interface con­nected over the serial interface in the positioner.
Use the TROVIS-VIEW software with 3730-5 device module installed.
To connect the positioner directly to the PC via the local serial interface, an adapter (or­der no. 1400-7700) is required.
The positioner can be supplied with power by connecting it to a fieldbus segment or over a DC voltage source (9 to 32 V) con­nected to the bus terminals in the positioner. The simultaneous operation of TROVIS-VIEW and the fieldbus system is possible without any restrictions when con­nected to a FOUNDATION Fieldbus bus segment.
6 Status and diagnostic alarms
The Type 3730-5 Positioner contains inte­grated diagnostics to generate classified sta­tus and diagnostic alarms.

6.1 Standard EXPERT diagnostics
The standard EXPERT diagnostics provides information about positioner states such as operating hours counter, process monitor­ing, number of zero calibrations and initializations, total valve travel, tempera­ture, initialization diagnostics, zero/control loop errors, logging of the last 30 alarms, etc.
In addition, the standard EXPERT diagnostics generates diagnostic and status alarms which allow faults to be pinpointed quickly when a fault occurs.
In addition to the alarms being displayed on the positioner display, the classified alarms are also available over the device descrip­tion (DD).
Alarms are classified in the following main groups:

6.3 Classification of the status alarms and the condensed status
The alarms are classified in the positioner, i.e. when an alarm is issued, it is assigned a status. The classification of the states can be altered. To provide a better overview, the positioner state is summarized in a condensed state. This CONDENSED_STATE is made up from a summary of all classified status alarms is­sued by the positioner and is available in the RESOURCE_BLOCK. In addition, the CONDENSED_STATE also appears on the display of the positioner. The status of the individual alarms can be assigned as required in the ERROR_OPTS parameter. The following states can be selected:

Logging and displaying diagnostic func­tions/alarms
The last 30 alarms are logged in the positioner. An alarm that is repeated is only logged when it first occurs.
The alarms and the CONDENSED_STATE appear on the display as described in the code list (section 12). In addition, the diag­nostic parameters are available over the DD.
The diagnostic functions can easily be dis­played and configured using the TROVIS-VIEW software connected over the local interface (SSP).
7 Adjusting the limit switch
The positioner version with an inductive limit switch has one adjustable tag (1) mounted on the shaft which operates the proximity switch (3).
For operation of the inductive limit switch, the corresponding switching amplifier (see section 3.2.1) must be connected to the out­put.
If the tag (1) is inside the field of the switch, the switch assumes a high resistance. If the tag is outside of the field, the switch assumes a low resistance.
Normally, the limit switch is adjusted such that it will provide a signal in both end posi­tions of the valve. The switch, however, can also be adjusted to indicate intermediate valve positions.
The desired switching function, i.e. whether the output relay shall be picked up or re­leased when the tag has entered the field, has to be determined, if necessary, at the switching amplifier.
Setting the switching point:
Important!
During adjustment or testing, the switching point must always be approached from mid-position (50 %).
To ensure safe switching under any ambient conditions, the switching point should be adjusted to a value of approx. 5 % before the mechanical stop (OPEN – CLOSED).
52 EB 8384-5 EN
Page 53
Adjusting the limit switch
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 adjust­ment screw (2) until the tag enters or leaves the field and the switching ampli­fier responds. You can measure the switching 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 ad­justment screw (2) until the tag enters or leaves the field of the proximity switch (3). You can measure the switching voltage as an indicator.
Contact function:
Tag leaving the field > Contact is made. Tag entering the field > Contact is opened.

Maintenance
10 Maintenance
The positioner does not require any mainte­nance.
There are filters with a 100µm mesh size in the pneumatic connections for supply and output which can be removed and cleaned, if required.
The maintenance instructions of any up­stream supply air pressure reducing stations must be observed.
11 Servicing explosion-protected
devices
If a part of the positioner on which the ex­plosion protection is based needs to be ser­viced, the positioner must not be put back into operation until an expert has inspected the device according to explosion protection requirements, has issued a certificate stating this or given the device a mark of confor­mity.
Inspection by an expert is not required if the manufacturer performs a routine test on the device prior to putting it back into opera­tion. The passing of the routine test must be documented by attaching a mark of confor­mity to the device.
Explosion-protected components may only be replaced by original, checked compo­nents from the manufacturer.
Devices that have already been used outside of hazardous areas and are intended for use in hazardous areas in future must com­ply with the safety demands placed on re­paired devices. Prior to operation, they must be tested according to the specifications sti­pulated for "Repairing explosion-protected devices".

Example: In some applications, it makes sense to limit the valve travel, e.g. if a certain minimum medium flow is required or a maximum flow must not be reached. The lower limit must be adjusted with Code 10, and the upper limit with Code 11. If a tight-closing function has been set up, it has priority over the travel limitation!
When set to OFF, the valve can be opened past the nominal travel with a reference variable outside of the 0 to 100 % range.

If w approaches the percentage adjusted at the final value that causes the valve to open, the actuator is immediately completely filled with air (with AIR TO OPEN) or vented (with AIR TO CLOSE).

Example: Set the final position w > to 99 % for three-way valves.
The pressure limit determined during initialization is displayed and can changed. (Only for fail-safe position valve closed/AIR TO OPEN, for valve open/AIR TO CLOSE, always set it to

after initialization, i.e. complete supply pressure to the actuator. The signal pressure can also be limited already prior to initializa­tion to protect against impermissibly high actuating forces). Note: After changing a pressure limit already set, the actuator must be vented once (e.g. by selecting the fail-safe position over Code 0). The pressure limit must always be set to OFF after initialization for double-acting actuators.

These instructions are based on the following:
Fieldbus Foundation Specification "Function Block Application Process Part 1 to 3" Revision
1.5. Fieldbus Foundation Specification "Transducer Block Application Process Part 1 to 2" Revi­sion PS 3.0.
13.2 Device description (DD)
For integration of the device described into the host system, the following device description files are needed:
Device Description: < 0101.ffo >, < 0101.sym > Capabilities File: < 010101.cff >
These device description files can be downloaded from the Internet, for example, at www.fieldbus.org or www.samson.de.
13.3 Notes concerning the parameters
All time specifications in the Resource Block are specified in the unit of 1/32 ms according to the Fieldbus Specification Version 1.5. In the Device Description Library supplied by FOUNDATION Fieldbus which the device de­scription of 3730-5 is also based upon, these parameters are incorrectly specified as ms. The specified values supplied by the device are, however, always to be interpreted as the unit of 1/32 ms. Due to the same reason, "Fault state to value" is indicated as "Fault state type" in the IO_OPTS parameter of the AO Function Block. Several parameters can only be modified in certain modes (see Read/write capability in the parameter description). In this case, not the actual mode is decisive, but the target mode.

Parameter description
13.4 FOUNDATIONTMFieldbus block model
FOUNDATION Fieldbus assigns all the functions and data of a device to three different types of blocks. Each type of block has a different range of tasks to fulfill in the block model. The following types of blocks are implemented in the SAMSON Type 3730-5 Positioner:
One Resource Block
4
The Resource Block contains all the specific characteristics associated with a device on the Fieldbus, for example, device name, manufacturer number and serial number. A device can only have one Resource Block.
One AO Transducer Block
4
Each AI or AO Function Block has a Transducer Block which contains all data and de­vice-specific parameters to connect the device to the process value (sensor or actuator). The positioner output signal can be directly influenced over the AO Transducer Block.
Two DI Transducer Blocks
4
The DI Transducer Blocks connect binary input signals for transmission and processing over the fieldbus.
One Analog Output Function Block
4
Function blocks are responsible for the control behavior of a FOUNDATION Fieldbus de­vice. A FOUNDATION Fieldbus application can be configured by connecting the inputs and outputs of function blocks. The AO Function Block converts the output value from an upstream function block into a control value for the valve.
EB 8384-5 EN 77
Page 78
Parameter description
Two Discrete Input Function Blocks
4
The DI Function Blocks are used as inputs to control binary signals. They support the se­lection of binary switching conditions of various functions.
One PID Function Block
4
The PID controller has a flexible proportional-integral-differential control algorithm which can be configured as required to match the application.
13.5 Resource Block
The Resource Block contains all the data that identify the device. It is similar to an electronic device tag.
Resource Block parameters include device type, device name, manufacturer ID, serial num­ber as well as parameters which affect the behavior of all other blocks of the device.

Contains the output value received from the upstream Analog Output Function Block.
Final position if set point above adjusted value.
If the set point exceeds the adjusted value, the valve is moved to the final position that corresponds to 100 % of the manipulated variable. This causes the actuator to either be vented completely or fully filled with air (corresponding to the fail-safe action).

99 %
Note! The function is deactivated by entering –2.5 %.
As this function causes the actuator to be fully vented or filled with air, the valve moves to its absolute final position. Restrictions set by the travel range or travel limitation functions do not apply. In the case that this creates excessive positioning forces, this function must be deactivated.
