!WARNING
The instrument must only be installed and commissioned by qualified
personnel.
The instrument is designed for connection to functional and safety
extra low voltage.
The instrument is designed for connection to operate voltage or safety
extra--low voltage.
Electrical safety depends only on the power supply equipment.
Pneumatic actuators exert considerable positioning forces. The safety
precautions of the actuator used must therefore be scrupulously
observed during installation and commissioning in order to prevent
injuries.
We explicitly draw your attention to the necessity of observing safety
regulations regarding operation in zones subject to explosion hazard, if
applicable.
The specifications of the examination certificate valid in your country
must be observed. Laws and regulations valid in your country must be
observed for the electrical installation in explosions hazardous areas.
In Germany these are for example:
-- Working reliability regulations,
-- Regulations for installing electrical equipment in hazardous areas,
DIN EN 60079--14 (in the past VDE 0165, T1).
It should be checked whether the available power supply, insofar as
this is required, is compliant with the power supply specified on the
rating plate and specified in the examination certificate valid in your
country.
Take care to avoid electrostatic discharges within the hazardous area,
such as can arise if a dry cloth is used to clean the positioner in the
plastic housing.
Devices with the protection type ”flameproof enclosure” may only be
opened when the power is off.
!WARNING
Devices with the protection type ”intrinsically safe” lose their
certification as soon as they are operated with circuits that do not
conform to the specifications laid down in the EC type examination
certificate valid in your country.
The successful and safe operation of this equipment is dependent
upon its proper handling, installation, operation and maintenance.
!WARNING
The device may not be operated as long as the quick start guides are
inside the housing.

Introduction
1.1 General information about the positioner
The positioner is used to adjust and control pneumatic actuators. The
controller operates electropneumatically with compressed air as an
energy supply.
The positioner together with the PROFIBUS PA communications
interface are components in a digital process automation system. It
communicates with the master as a slave via the PROFIBUS PS field
bus. The field bus is used not only for communication but also to supply
the positioner with electrical power.
For example, the positioner can be used to control valves as follows:
Swith linear actuator (figure 1, page 15) or
Swith part--turn actuator VDI/VDE 3845 (figure 2, page 15)
Different mounting types are available for linear actuators:
SNAMUR or IEC534
Sintegrated mounting to ARCA
Sintegrated mounting to SAMSON (non explosion proof version)
This means the positioner can be installed and operated on all common
actuator systems.
The positioner is available for the following actuators:
Sdouble--acting and
Ssingle--acting
For following applications:
Spotentially explosive or
Snot potentially explosive applications.
The electronics with display, position feedback and valve block are
integrated in the housing.

A5E00127926--05
The housing is available in three versions:
SPlastic housing for single-- and double--acting actuators
SMetal housing for single--acting actuators
SExplosion proof housing for single and double--acting actuators
The device is designed with IP66/NEMA4x degree of protection.
The intrinsically safe version can be used in hazardous areas in zone 1
or zone 2.
The explosion proof version can be used in hazardous areas in zone 1
or zone 2.
Explosion proof type ”n” versions can be used in explosion hazard zone
2 areas.
The positioners (version 6DR551* for single acting actuators) are also
suitable for positioning on fittings with pneumatic actuators, which sat-
isfy the special requirements for safety devices up to SIL 2 to
IEC 61508 part 1--7 and IEC 61511 part 1--3. For this the SIL safety
instructions in the ”SIL Safety Manual (PA/FF)” order number
A5E00489773 must be followed.
The positioner can be expanded with various options modules (chapter
2.6, page 31). The following modules are available in all:
SIymodule: Two--wire current output 4 to 20 mA for position feedback
SAlarm module: three digital outputs and 1 binary input
SSIA module: one binary output for fault messages, two binary
outputs for limit value alarms
SMechnical limit switch module: one binary output for the output of a
group error message, two switches for signalling two limit values
that can be set mechanically.
SManometer block: 2 or 3 manometers for single and double--
acting positioners
SConnection block (NAMUR) for safety valve block
SMounting kits for linear and part--turn actuator
For decentralized installation of the positioner and position sensor:
SExternal position detection system
SNon-Contacting Position Sensor (NCS)
Only environmentally friendly materials have been used in the
construction of the positioner.

1.2 General information regarding PROFIBUS
The PROFIBUS PA (PA = Process Automation) is a variant of the
PROFIBUS--DP (DP = Decentral Peripheral) which is widely used in
manufacturing engineering.
The PROFIBUS (Process Field Bus) is an open communication
system for automation engineering and thousands are used all over the
world. It is specified in the European standard EN 50170.
1.2.1 Transmission method
The PROFIBUS PA has a special transmission method and therefore
satisfies the requirements of process automation and manufacturing
engineering. This transmission method is defined in the international
standard IEC61158--2. The low transmission speed reduces the power
loss compared to the PROFIBUS--DP and therefore enables an
intrinsically safe technique for use in hazardous areas.
1.2.2 Topology
The bus topology can, to a large extent, be freely selected so that line,
star and tree structures are possible, as well as mixtures of these. All
kinds of field devices such as transformers, actuators, analyzers, etc.
can be connected to the PROFIBUS PA
The main advantage is in:
Sthe saving of installation costs
Sthe possibility of more extensive diagnostics with an increase in the
availability of system parts
Sthe possibility of automatic tracing of system documentation
Sthe possibility of system optimization in operation
In an automation system, several PROFIBUS PA channels are usually
connected to the fast PROFIBUS--DP with coupling units. The process
control system is also linked to this.
Both bus systems use a uniform protocol layer. This makes the
PROFIBUS PA a communication--compatible extension of the
PROFIBUS--DP into the field.

Figure 5 Typical PROFIBUS automation system
Figure 5 shows the section of a typical PROFIBUS automation system.
The control system consists of two masters with distributed tasks.
The class 1 master looks after the control and regulation functions,
while the class 2 master enables operating and monitoring functions. A
cyclic exchange of measuring and setting data takes place between
master 1 and the field devices. Parallel to this data, the status data of
the field devices is transmitted to and evaluated in the class 1master.
No field device parameters are set or other device information read
during cyclic operation.
The information necessary for establishing communication is available
to the control system from the stored, device--specific device master
data (GS*) files. The files are available on the Internet at:
www.siemens.com/sipartps2
Click on “More Info” and “--> Instructions and Manuals”.
One or more class 2 masters can access the field devices acyclically in
addition to the cyclic mode. With this communication type further
information can be fetched from the devices or settings made in the
devices.
1.2.3 Properties of the PROFIBUS PA
The PROFIBUS PA enables bi--directional communication between a
bus master and the field devices via a shielded two--wire line. At the
same time the power is supplied to the two--wire field devices on the
same lines.
