Safety Guidelines
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
with a safety alert symbol, indicates that minor personal injury can result if proper precautions are not taken.
CAUTION
without a safety alert symbol, indicates that property damage can result if proper precautions are not taken.
NOTICE
indicates that an unintended result or situation can occur if the corresponding information is not taken into
account.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The device/system may only be set up and used in conjunction with this documentation. Commissioning and
operation of a device/system may only be performed by qualified personnel. Within the context of the safety notes
in this documentation qualified persons are defined as persons who are authorized to commission, ground and
label devices, systems and circuits in accordance with established safety practices and standards.
Prescribed Usage
Note the following:
WARNING

2.4 Measures
For the sake of safety, the following precautions must be observed:
WARNING
Type of protection "pressure-proof encapsulation"
Devices with "pressure-proof encapsulation" protection may only be opened when off
circuit.
"Intrinsically safe" protection type
"Intrinsically-safe" devices lose their certification as soon as they are operated on circuits
which do not correspond with the test certification valid in their country. The "ia" protection
level of the device is lowered to the "ib" protection level if intrinsically safe circuits with the
"ib" protection level are connected.
Protection type "limited energy" nL (zone 2)
Devices with "limited energy" may be connected and disconnected while in operation.
Protection type "non-sparking" nA (zone 2)
Devices with "non-sparking" protection may only be connected and disconnected when off
circuit.
Exceptions:
Connection lines with unlimited energy as well as internal connectors may be connected or
disconnected under voltage only in the following cases:
•During installation
•During maintenance
•During repairs
WARNING
Exposure to aggressive and hazardous media
The device can be operated both at high pressure and with aggressive and hazardous
media. Therefore, improper use of this device may lead to serious injury and or
considerable damage to property. Above all, it must be noted when the device was in use
and is to be exchanged.
CAUTION
For versions 6DR5a*b-*Gc**-****, where a = 0, 2, 5, 6; b = 0, 1; c = G, N, M, P, Q, the
following is applicable:
The device must be protected against power surges of over one joule.
For versions 6DR5a*b-*Gc**-****, where a = 0, 2, 5, 6; b = 0; c = G, N, M, P, Q, the
following is applicable:
The maximum torque on the thread of the cable gland should not exceed 67 Nm.

CAUTION
Electrostatic Sensitive Devices (ESD)
This device contains electrostatic sensitive devices. Electrostatic sensitive devices may be
destroyed by voltages that are undetectable to a human. Voltages of this kind occur as
soon as a component or an assembly is touched by a person who is not grounded against
static electricity. The damage to a module as a result of overvoltage cannot usually be
detected immediately. It may only become apparent after a long period of operation.
Therefore, avoid electrostatic charge.
2.5 Qualified Personnel
Qualified personnel are people who are familiar with the installation, mounting,
commissioning, and operation of the product. These people have the following qualifications:
● They are authorized, trained or instructed in operating and maintaining devices and
systems according to the safety regulations for electrical circuits, high pressures and
aggressive as well as hazardous media.
● For explosion-proof devices: They are authorized, trained, or instructed in carrying out
work on electrical circuits for hazardous systems.
● They are trained or instructed in maintenance and use of appropriate safety equipment
according to the safety regulations.
● They should be trained in first aid.

Description 3
3.1 Function
● The electropneumatic positioner and an actuator form a control system. The current
position of the actuator is recorded by a servo potentiometer and the actual value x is fed
back. The setpoint and the actual value are simultaneously shown on the digital display.
● The reference variable w is provided digitally through the PROFIBUS.
● The positioner works as a predictive, anticipatory five-point controller whose output
variable ±Δy is used to control the integrated servo valves based on the pulse length
modulation method.
● These input signals change pressure in the actuator chamber(s) and displace the
actuator until the control deviation becomes zero.
● When the enclosure cover has been removed, the device can be operated and
configured using three buttons and the digital display.
● The standard controller has one binary input (BE1) by default. This binary input can be
configured individually, and be used to block the operating modes.
● It has a friction clutch and a switchable gear so that the positioner can be used with
different mechanical part-turn and linear actuators.
3.2 Structure
3.2.1 Design overview
The mechanical and electrical assembly, the device components and functional principle of
the positioner are described in the following chapter.
The positioner and the PROFIBUS PA communication interface function as components in a
digital process automation system. It functions as a slave and communicates with the master
through the PROFIBUS PA fieldbus. Apart from communication, the fieldbus also supplies
electrical auxiliary power to the positioner.
The positioner is available in the following configurations:
● SIPART PS2 PA without explosion protection in the metal or plastic enclosure
● SIPART PS2 PA with EEx ia/ib protection in the metal or plastic enclosure
● SIPART PS2 PA with EEx d protection in the flameproof enclosure

The positioner is used to move and control pneumatic actuators. The positioner works
electropneumatically; compressed air is used as an auxiliary power supply. The positioner is
used to control valves with:
● Linear actuator
● Part-turn actuator VDI/VDE 3845
Difference attachment extensions are available for linear actuators:
● NAMUR or IEC 534
● Integrated attachment to ARCA
● Integrated attachment to SAMSON in the non-flameproof enclosure
The positioner can be installed on or operated using the customary drives.
