SIPART PS2 EEx d electropneumatic positioner in flameproof casing

SIPART PS2 in stainless steel casing

The SIPART PS2 electropneumatic positioner is used to control
the final control element of pneumatic linear or part-turn actua­tors. The electropneumatic positioner moves the actuator to a
valve position corresponding to the setpoint. Additional function
inputs can be used to block the valve or to set a safety position.
A binary input is present as standard in the basic device for this
purpose.

Stainless steel casing for extreme ambient conditions

The SIPART PS2 is available in a stainless steel casing (without
window in the lid) for use in particularly aggr
(e.g. offshore operation, chlorine plants etc.). The device func­tions are the same as those of the basic versions.

■

Design

The SIPART PS2 positioner is a digital field device with a highly­integrated microcontroller.

The positioner consists of the following components:

• Casing and cover

• PCB with corresponding electronics with or without communi­cation through HART
or with electronics for communication in accordance with

- PROFIBUS PA specification, IEC 61158-2; bus-supplied de-

vice, or

- FOUNDATION Fieldbus (FF) specification, IEC 61158-2,

bus-supplied device

• Actuator travel detection system

• Terminal housing with screw terminals

• Pneumatic valve manifold with piezoelectric valve precontrol.

The valve manifold is located in the housing, the pneumatic con­nections for the inlet air and the positioning pressure on the right­hand side. A pressure gauge block and/or a safety solenoid
valve can be connected there as options. The SIPART PS2 posi­tioner is fitted to the linear or part-turn actuator using an appro­priate mounting assembly. The circuit board container in the
casing provides slots for separately ordered boards with the
following functions:

is carried out directly on the actuator. The controller unit can then
be fitted a certain distance away, e.g. on a mounting pipe or sim­ilar, and is connected to the travel detection system by an elec­tric cable and to the actuator by one or two pneumatic lines.

conditions at the fitting exceed the specified values for the posi­tioner (e.g. strong vibrations).

The following can be used for measuring the travel or angle:

• NCS sensor

• External position detection system C73451-A430-D78

• A commercially available potentiometer (10 kΩ resistance)
(e.g. for higher application temperatures or customer-specific
applications)

The use of linear potentiometers is recommended for very small ac­tuators with a short valve travel since, on the one hand, the space
required by the linear potentiometer is very small and, on the other,
the transmission characteristic is optimum for a small travel.

SIPART PS2

Technical description

The NCS sensor consists of a non-contacting position sensor. All
coupling elements are omitted such as coupling wheel and
driver pin with part-turn actuators or lever and pick-up bracket
with linear actuators up to 14 mm travel.

This results in:

• Even greater resistance to vibration and shock

• No wear of sensor

• Problem-free mounting on very small actuators

• Negligible hysteresis with very small travels.

The sensor does not require an additional power supply, i.e.
SIPART PS2 (not for EEx d version) can be operated in a 2-wire
system. The NCS (N
potted sensor housing which must be mounted permanently and
a magnet which is mounted on the spindle of linear actuators or
on the shaft butt of part-turn actuators. For the version for travels
>14 mm (0.55 inch), the magnet and the NCS are premounted
on a stainless steel frame and offer the same interface mechan­ically as the positioner itself, i.e. they can be mounted using the
standard mounting kits 6DR4004-8V, -8VK and -8VL.

The installation of a EMC filter module in the positioner (controller
unit) is necessary in order to ensure a connection level with EMC
according to EN 61326/A1 and NAMUR NE21 when using exter­nal sensors (see Ordering data for "EMC filter module")

■

Function

The SIPART PS2 electropneumatic positioner works in a com­pletely different way to normal positioners.

Mode of operation

Comparison of the setpoint and the actual value takes place

onically in a micr

electr
deviation, it uses a 5-way switch procedure to control the piezo­electric valves, which regulates the flow of air into and from the
chambers of the pneumatic actuator or blows it in the opposite
direction.

The microcontroller then outputs an electric control command to
the piezoelectric valve in accordance with the size and direction
of the deviation (deviation between setpoint w and control
output x). The piezoelectric valve converts the command into a
pneumatic positional increment.

The positioner outputs a continuous signal in the area where
there is a large control deviation (high-speed zone); in areas of
moderate control deviation (slow-speed zone) it outputs a se­quence of pulses. No positioning signals are output in the case
of a small control deviation (adaptive or variable dead zone).

The linear or rotary motion of the actuator is detected by the
mounting assembly and transferred to a high-quality potentio­meter made of plastic conductive material over a shaft and a
non-floating gear transmission.

The angular error of the pick-up in cases where the assembly is
mounted on a linear actuator is corrected automatically.

When connected in a 2-wire system, the SIPART PS2 draws its
power exclusively from the 4 to 20 mA setpoint signal. The elec­tric power is also connected through the 2-wire bus signal with
PROFIBUS operation (SIPART PS2 PA). The same applies for the
FOUNDATION Fieldbus version.

The SIMATIC PDM communications software permits easy re­mote operation and monitoring using a PC or laptop. The posi­tioner can also be configured using this program. Parameters
which provide important information for maintenance and fault
diagnosis of the complete unit can also be determined using
process data and comparison data.

When operating the SIPART PS2 through the HART interface, the
connection is made directly to the 2-wire cable to the
SIPART PS2 positioner through a HART modem that can be con­nected to the RS 232 or USB interface. The signals needed for
communication in conformity with the HART protocol are super­imposed on the current signal in accordance with the F

hift Keying (FSK) method.

Low air consumption

A hallmark of the SIPART PS2 is its own extremely low consump­tion of air. Nor
costly. Thanks to the use of modern piezoelectric technology, the
SIPART PS2 consumes air only when it is needed, which means
that it pays for itself within a very short time

SIPART PS2

Technical description

Status monitoring with 3-stage alarm concept

The intelligent electropneumatic SIPART PS2 positioner is
equipped with additional monitoring functions. The status indi­cations derived fr
faults of the unit. The severity of these faults ar
"traffic light signaling", symbolized by a wrench in the colors
green, yellow and red (with SIMATIC PDM and Maintenance Sta­tion):

• Need for maintenance (green wrench)

• Urgent need for maintenance (yellow wrench)

• Imminent danger of unit failure or general failure (red wrench)

This allows users to put early measures into action in the run-up
to a serious valve or actuator fault, which can prevent an immi­nent system shutdown. The fact that a fault indication is sig­naled, such as the onset of a diaphragm break in the actuator or
the progressive sluggishness of a unit, enables the user to en­sure system reliability at any time by means of suitable mainte­nance strategies.

This three-stage alarm hierarchy also allows early detection and
signaling of other faults, such as the static friction of a packing
box, the wearing of a valve plug/seating, or precipitations or in­crustations on the fittings.

These fault indications can be output either line-conducted over
the alarm outputs (see above) of the positioner (max. 3), or via
communication over the HART or fieldbus interfaces. In this
case, the HART, PROFIBUS and FF versions of SIPART PS2 per­mit a differentiation of the various fault indications, as well as a
trend representation and histogram function of all key process
variables with regard to the fittings.

The LCD of the device also displays the graded maintenance re­quirements, complete with identification of the source of the fault.

Functional safety acc. to SIL 2

The SIPART PS2 positioners are also suitable for control of fit­tings, which meet the special r
safety up to SIL 2 to IEC 61508 or IEC 61511-1.

This is a single-action, venting positioner with an input of 4 to
20 mA, PROFIBUS PA and FOUNDATION Fieldbus (FF) for
mounting on pneumatic actuators with spring return.

The positioner vents the valve actuator on demand or in the
event of a fault and puts the valve in the preset safety position.

This positioner meets the following requirements:

• Functional safety up to SIL 2 to IEC 61508 or IEC 61511-1,
from firmware version C4 or higher for safe venting

• Explosion protection for the versions 6DR5...-.E...

• Electromagnetic compatibility to EN 61326/A1, Appendix A.1

P
performs two tasks in a single device (without extra wiring)

• Firstly, it switches the fitting off on demand by venting the ac­tuator (functional safety acc. to SIL 2 (see above)

• Secondly, it can perform a Partial Stroke Test at regular inter­vals (1 - 365 days), which prevents the blocking of the fitting,
e.g. due to corrosion or furring.

As in this case SIPART PS2 is constantly working in normal op­eration (e.g. 99 % position), it also acts as a permanent test func­tion for the pneumatic output circuit, which is not usually possi­ble when using a solenoid valve.

Solenoid valves on control valves can also not normally be
tested during operation. They are therefore not necessary when
using SIPART PS 2 with a 4-wire connection system as the vent­ing is carried out on demand by SIPART PS2. This means that on
control valves, both the control function and the shut-off function
can be carried out by a single device.

• Input current range 0 to 20 mA or 4 to 20 mA

• Rising or falling characteristic at the setpoint input

• Positioning speed limit (setpoint ramp)

• Split-range operation; adjustable start-of-scale and full-scale
values

• Response threshold (dead zone); self-adjusting or fixed

• Direction of action; rising or falling output pressure with rising
setpoint

• Limits (start-of-scale and full-scale values) of positioning
range

• Limits (alarms) of the final control element position; minimum
and maximum values

• Automatic "tight shut-off" (with adjustable response threshold)

• The travel can be corrected in accordance with the valve char­acteristic.

• Function of binary inputs

• Function of alarm output etc.

The key aspects of configuring the different SIPART PS2 ver­sions are largely identical.
