documentation or on the product itself) is essential,
in order to avoid faults, which in themselves might
directly or indirectly cause severe personal injury or
property damage.
1.3
Protective clothing
FLOWSERVE products are often used in problematic
applications (e.g. extremely high pressures, dangerous, toxic or corrosive mediums). In particular valves
with bellows seals point to such applications. When
performing service, inspection or repair operations
always ensure, that the valve and actuator are depressurised and that the valve has been cleaned and is free
from harmful substances. In such cases pay particular
attention to personal protection (protective clothing,
gloves, glasses etc.).
1.4 Qualified personnel
Qualified personnel are people who, on account of their
training, experience and instruction and their knowledge of relevant standards, specifications, accident
prevention regulations and operating conditions, have
been authorised by those responsible for the safety of
the plant to perform the necessary work and who can
recognise and avoid possible dangers.
1.5 Installation
DANGER: Before installation check the order-no,
serial-no. and/or the tag-no. to ensure that the valve/
actuator is correct for the intended application.
Do not insulate extensions that are provided for hot
or cold services.
Pipelines must be correctly aligned to ensure that the
valve is not fitted under tension.
DANGER: indicates that death, severe personal
injury and/or substantial property damage will
occur if proper precautions are not taken.

1.7 Service / repair
To avoid possible injury to personnel or damage to
products, safety terms must be strictly adhered to.
Modifying this product, substituting nonfactory parts,
or using maintenance procedures other than outlined
in this instruction could drastically affect performance
and be hazardous to personnel and equipment, and
may void existing warranties. Between actuator
and valve there are moving parts. To avoid injury
FLOWSERVE provides pinch-point-protection in the
form of cover plates, especially where side-mounted
positioners are fitted. If these plates are removed
for inspection, service or repair special attention is
required. After completing work the cover plates must
be refitted.
1.9 Valve and actuator variations
These instructions cannot claim to cover all details
of all possible product variations, nor in particular
can they provide information for every possible
example of installation, operation or maintenance. This
means that the instructions normally include only the
directions to be followed by qualified personal where
the product is being used for is defined purpose. If
there are any uncertainties in this respect particularly
in the event of missing product-related information,
clarification must be obtained via the appropriate
FLOWSERVE sales office.

has not been provided (a form can be obtained from
FLOWSERVE).
1.8 Storage
In most cases FLOWSERVE products are manufactured
from stainless steel. Products not manufactured
from stainless steel are provided with an epoxy resin
coating. This means that FLOWSERVE products
are well protected from corrosion. Nevertheless
FLOWSERVE products must be stored adequately
in a clean, dry environment. Plastic caps are fitted
to protect the flange faces to prevent the ingress of
foreign materials. These caps should not be removed
until the valve is actually mounted into the system.

3 LOGIX 510si OVERVIEW
The Logix 510si is a two-wire, 4-20 mA input digital valve
positioner. The Logix 510si positioner controls singleacting actuators with linear and rotary mountings. The
Logix 510si is completely powered by the 4-20 mA input
signal. The minimum input signal required to function
is 3,6 mA.
4 SPECIFICATIONS
User Instructions Logix 510si - LGENIM0510-02 12/13
Since the positioner is insensitive to supply pressure
changes and can handle supply pressures from 1,5 to
6 barg (22 to 87 psig), a supply regulator is usually not
required; however, in applications where the supply pressure is higher than the maximum actuator pressure rating
a supply regulator is required to lower the pressure to
the actuator’s maximum rating (not to be confused with
operating range). A coalescing air filter is recommended

for all applications due to the close tolerances in the
positioner. Optional analog feedback system as well
as limit switch unit and a directly attachable double
acting module complete the Logix 510si positioner
accessories.
NOTE:The air supply must conform to ISA 7.0.01or
IEC 770 (a dew point at least 10 ˚C / 18 ˚F below ambient temperature, particle size below five microns – one
micron recommended – and oil content not to exceed
one part per million).
5 PRINCIPLE OF OPERATION
The Logix 510si positioner is a digital positioner with
various options. The positioner consists of three main
modules:
1. The microprocessor-based electronic control
module includes direct local user interface switches
2. The piezo valve-based electro-pneumatic converter
module
3. The infinite resolution valve position sensor.

&RQWURO9DOYH
The basic positioner operation is best understood by refer-
ring to Figure 1. The complete control circuit is powered
by the two-wire, 4-20 mA command signal. The analog
4-20 mA command is passed to the microprocessor,
where it is compared to the measured valve stem position. The control algorithm in the processor performs
control calculations and produces an output command
to the piezo valve, which drives the pneumatic amplifier.
The position of the pilot valve in the pneumatic amplifier
is measured and relayed to the inner loop control circuit.
This two-stage control provides for more responsive and
tighter control than is possible with a single stage control
algorithm. The pneumatic amplifier controls the airflow to
the actuator. The change of pressure and volume of the air
in the actuator causes the valve to stroke. As the valve approaches the desired position, the difference between the
commanded position and the measured position becomes
smaller and the output to the piezo is decreased. This,
in turn, causes the pilot valve to close and the resulting
flow to decrease, which slows the actuator movement as
it approaches the new commanded position. When the
valve actuator is at the desired position, the pneumatic
amplifier output is held at zero, which holds the valve in
a constant position.

7 WIRING AND GROUNDING GUIDELINES
Electrical connections: signal cable with cable passage
(NPT, or M20 x 1,5) to terminals 2 x 2,5 mm
Input signal: 4 – 20 mA
NOTE:Observe the minimum requirements of voltage
and equivalent electrical load: 6,0 VDC / 300 ȍ / at
20 mA
The performance is ensured only for a minimum input
current of 3,6 mA.
For wiring, the following notes should be observed:
NOTE:The input loop current signal to the Logix 510si
should be in shielded cable. Shields must be tied to a
ground at only one end of the cable to provide a place
for environmental electrical noise to be removed from
the cable. In general, shield wire should be connected
at the source. (Figure 2)
Connect the 4-20 mA current source to terminals +11
and -12 (Figure 2).
2. Supply air should meet IEC 770 or ISA 7.0.01
requirements. A coalescing filter should be installed in
front of the supply air connection Z. Now connect the
air supply to the filter, which is connected to the Logix
500 Series positioner.
3. With a maximum supply pressure of 6 bar (87 psi)
a regulator is not required.
4. With an operating pressure of more than
6 bar (87 psi), a reducing regulator is required. The
flow capacity of the regulator must be larger than the
air consumption of the positioner (7 Nm
3
/h @ 6 bar /
4,12 scfm @ 87 psi).
5. Connect the outlet connector Y of the positioner
to the actuator with tubing, independent of the action
6
(direct or reverse).
Grounding Screw
The grounding screw, located inside the positioner
cover, should be used to provide the unit with an adequate and reliable earth ground reference. This ground
should be tied to the same ground as the electrical
conduit. Additionally, the electrical conduit should be
earth grounded at both ends of its run. The grounded
screw must not be used to terminate signal shield wires.
Compliance Voltage (Figure 3)
Output compliance voltage refers to the voltage limit
the current source can provide. A current loop system
consists of the current source, wiring resistance, barrier
resistance (if present), and the Logix 510si impedance.
