INTRODUCTION
The FY301 is a smart valve positioner for Single (spring return) or Double acting Linear motion type
control valves e.g. Globe, Gate, Diaphragm, Pinch or Clamp and Rotary motion type control valves e.g.
Ball, Butterfly or Plug with pneumatic type actuators e.g. Diaphragm, Piston, Vane, or Bellows. It is
based on a field-proven piezo flapper and non-contacting Hall-effect position sensor that provides
reliable operation and high performance. The digital technology used in the FY301 enabled the choice of
several types of flow characterizations, an easy interface between the field and the control room, not to
mention several interesting features that considerably reduce the installation, operation and
maintenance costs.
The FY301, besides the normal functions offered by other smart positioners, offers the following
functions:
* Table - on top of the regular valve characterization curves like linear, equal percentage and quick
opening (hyperbolic), the valve set point signal may be custom linearized according to a 16 point table,
making it possible to achieve flow characterization being a combination of linear and equal percentage
etc.
* Local Adjustment - not only for travel adjustment, but also flow characterization, tuning, operation
mode, indication, set point and PID parameters... as well.
* Password - three levels for different functions.
* Operation Counter - shows the number of changes in each function.
* Auto Setup - automatic calibration of valve travel.
* Diagnostic – permanently valve monitoring condition for preventive maintenance.
Get the best results of the FY301 by carefully reading the instructions of this manual.
WARNING
Throughout the operation of the positioner, including auto setup, do not touch the moving parts of the
valve/actuator/positioner `set as they may unexpectedly move automatically. Make sure to disconnect
air supply before touching any moving parts.

1.1
INSTALLATION
General
NOTE
The installation carried out in hazardous areas should follow the recommendations of the IEC60079-14 standard.
The overall accuracy of measuring and control depends on several factors. In spite of the excellent
performance, the positioner must be adequately installed so that it may work well.
Among all factors that may affect the positioner accuracy, environmental conditions are the most
difficult to control. But there are ways to reduce the effects of temperature, humidity and vibration.
Installing the positioner in areas protected from extreme environmental changes can minimize
temperature fluctuation effects. In warm environments, the positioner should be installed to avoid, as
much as possible, direct exposure to the sun. Installation close to lines and vessels subjected to
high temperatures should also be av oided. If not possible to avoid it, consider using the remote
position sensor version.
Use thermal isolation to protect the positioner from external heart sources, if necessary.
Humidity is fatal to electronic circuits. In areas subjected to high relative humidity, the O-rings for the
electronic housing covers must be correctly placed and the covers must be completely closed by
tighten them by hand until you feel the O-rings being compressed. Do not use tools to tight the
covers. Removal of the electronics cover in the field should be reduced to the minimum necessary,
since each time it is removed; the circuits are exposed to the humidity.
The electronic circuit is protected by a humidity proof coating, but frequent exposures to humidity
may affect the protection provided. It is also important to keep the covers tightened in place. Every
time they are removed, the threads are exposed to corrosion, since painting cannot protect these
parts. Sealing methods should be employed on conduit entering of the positioner.
IMPORTANT
Avoid to use thread sealant tapes on the air input and outputs connections, since small pieces of this type of
sealant may block the air flow inside the positioner, affecting the overall equipment performance.
Although the positioner is practically vibration resistant, it is not recommended to install it near
pumps, turbines or other equipment producing too much vibration. If not possible to avoid it,
consider using of remote position sensor version.
Mounting
The FY301 mounting depends on the type of actuator, its actions, single (with spring return) or
double, and the movement characteristic (linear or rotary). It requires two mounting brackets: one for
the magnet and another for the positioner. Smar supplies both according to the specified ordering
code (see Page 6.4 for mounting bracket ordering code)
Additionally, a great variety of customized mounting brackets is available, covering several control
valves models from different manufacturers.
Check the availability and select the most adequate mounting bracket to your need, by visiting our
web page on the Internet: http://www.smar.com. Select "Valve Positioner" option to access the
product specific page. After enter your login and password, click on the Bracket for FY link and
choose the most appropriate mounting bracket to your application.
See below an example showing the Positioner with rotary and linear magnets.
IMPORTANT
Smar web site (www.smar.com) has options of mounting brackets available for several actuators of several
manufacturers and models and the related dimensional drawings.

Then, install the positioner bracket on the actuator. Usually, the actuator is designed according to
the VDI/VDE 3845 standard, and, in this case, tighten the four screws with their lock washers on the
proper bracket.

Installation
1.3
NOTE
Make sure that the arrow engraved on the magnet coincides with the arrow engraved on the positioner when
the valve is in mid travel.
When mounting the magnet, be sure that:
1. There is no attrict between the internal magnet face and t he position sensor salience during the
travel (rotary or linear), through the magnet.
2. The magnet and the salience of position sensor must not be distant.
A minimum distance of 2 mm and a maximum distance of 4mm are recommended between the magnet
external face and t he positioner face. For that, a centralizer device (linear or rotary) must be u sed. The
centralizer device is in the positioner packing.
Case the positioner installation or magnet change or if any other modification is done, the positioner
will require a re-calibration. See Section 3 (Setup - for Auto Setup procedure).
See item “Pneumatic Connections” as recommended practice to install the positioner to the valve
type.
Linear Movement
Install the magnet on the valve stem using its proper bracket, according to Figure 1.3.
Install the positioner bracket on the actuator. The fastening of the actuator bracket may follow the
NAMUR/IEC 60534-6-1 standard or be in accordance with the user specified boring. Mount the
positioner on the bracket by fastening the four screws in the holes of the pressure gauges opposite
face. Use lock washers to avoid loosening the screws.
The linear magnet movement must be or thogonal in relation to the main axis of the position
positioner. For example, if the linear magnet movement is vertical, the positioner main axis must be
horizontal, as show in Figure 1.3.

Make sure the bracket does not obstruct the exhaust outputs.
NOTE
Make sure that the arrow engraved on the magnet coincides with the arrow engraved on the positioner when
the valve is in mid travel.
When mounting the magnet, be sure that:
1. There is no attrict between the internal magnet face and the position sensor salience during the
travel (rotary or linear), through the magnet.
2. The magnet and the salience of position sensor must not be distant.
A minimum distance of 2 m m and a m aximum distance of 4mm are recommended between the magnet
external face and t he positioner face. For that, a c entralizer device (linear or rotary) must be us ed. The
centralizer device is in the positioner packing.
Case the positioner installation or magnet change or if any other modification is done, the positioner
will require a re-calibration. See Section 3 (Setup - for Auto Setup procedure).
Pneumatic Connections
The FY301 requires instrument air quality, following the best practices for pneumatic installations.
Consult the American National Standard "Quality Standard for Instrument Air" (ANSI/ISA S7.0.01 -
1996) for detailed information.
The FY301 comes with input and output stainless steel air filters, but these filters do not exclude the
preliminary instrument air treatment. Periodical filter cleaning is recommended at every 6 months or
less, if the air quality is not good. Please, check the maintenance section for clean the filters.
The FY301 supply air pressure varies from 1.4 bar (20 psi) minimum, to 7.0 bar (100 psi) maximum.
The actuator working pressure must follow these limits. Consider the use of boosters, if required.
Pressure below this range shall affect the positioner performance. Pressure above this range may
damage the positioner.
The two pneumatic outputs, marked as “OUT1” and “OUT2”, work in opposite directions to open or
close the valve.
IMPORTANT
If a failure occurs on the FY301, such as power loss (4-20 mA input signal), the output marked OUT1 goes to
zero pressure and the output marked OUT2 goes to the air supply pressure value.

Installation
1.5
The positioner can have pressure gages (see the ordering code table) attached to the supply air
input and in each output. The indications on gages are references only and does not have the same
overall positioner accuracy.
The pneumatic connections are marked with IN for the air supply and OUT1 and OUT2 for Output1
and Output2, respectively. Use 1/4 NPT connections with sealing material for the NPT screw
threads. Connect the air supply on t he connection marked IN. Be sure the air supply does not
exceed the maximum allowed pressure of the positioner or the actuator.
IMPORTANT
When using tape sealant type on the thread connections, be sure not spread small residues inside, since they
may clog the air flow inside the positioner and even impair the equipment efficiency.
The FY301 has five protected exhaust orifices with filters. Do not block any of these exhaust, as the
air must circulate freely through them. If painting the positioner block, remove the filters before, to
prevent them from being obstructed by paint. The orifices must be inspected on a r egular basis to
ensure they not blocked, granting the air to flow smoothly.
Double Action – Air to open (Close on failure)
Connect the positioner OUT1 output on the actuator connection marked with “OPEN” and connect
the positioner OUT2 output on the actuator connection marked with “CLOSE”.
Double Action – Air to close (Open on failure)
Connect the positioner OUT2 output on the actuator connection marked with “OPEN” and connect
the positioner OUT1 output on the actuator connection marked with “CLOSE”.
Single Action
Connect the positioner OUT1 output on the actuator input. Use a plug to block OUT2. Pay attention
to the safe logic on the actuator for the specific process. If necessary, invert the connections. Take
into consideration that in case of power failure the output marked OUT1 goes to zero pressure and
the output marked OUT2 goes to the air supply pressure value.

housing orifices and can be connected to a conduit. The wiring block has screws on which fork or
ring-type terminals can be fastened. See figure 1.8. Use a plug to block the electrical connection not
used. Tight it well and use thread sealing tape.
If the user choose protection against noise induced by atmospheric discharges, overloads, weld
machines and machines in general, it will be necessary to install a transient protector (Protector
acquired separately).
Test and communication terminals allow, respectively, to measure the current in the 4 - 20 mA loop,
without opening it, and to communicate with the transmitter. To measure it, connect a multimeter in
the mA scale in the "" and "" terminals, and to communicate, use a Hart® configurator in the
"COMM" and " " terminals. For convenience, there are three ground terminals: one inside the
cover and two externals, located close to the conduit entries.
Attention to prevent the accidental feeding of the test terminals. This occurrence will cause damages
in the equipment.
Figure 1.8 - Wiring Block
HAZARDOUS AREAS
In hazardous areas with explosion proof requirements, the covers must be tightened with at least 8 turns. In
order to avoid the penetration of humidity or corrosive gases, tighten the o-ring until feeling the o-ring
touching the housing. Then, tighten more 1/3 turn (120°) to guarantee the sealing. Lock the covers using
the locking bolts.
Conduit threads should be sealed by means of code-approved sealing methods.
Explosion proof, non-incendive and intrinsic safety certification are standards for FY301.

Use of twisted pair (22 AWG or greater than) cables is recommended.
Avoid routing signal wiring close to power cables or switching equipment.
The FY301 is protected against reverse polarity, and can withstand up to 50 mA and power supply
of ± 60 Vdc without damage.
The FY301 connection could be done according to the figures 1.10, 1.11 and 1.12.
It is also recommended to ground the shield of shielded cables at one end only. The non-grounded
end must be carefully isolated.
The configurator can be connected to the communication terminals of the positioner or at any point
of the signal line by using the interface HPI311-M5P with “alligator” clips.

The FY301 has an equivalent impedance of 550 Ohms. Make sure that the current supply or analog
output of DCS, CLP or single loop controller powering the positioner is capable to handle a voltage
drop of 11 V for each positioner (550 x 0.02 = 11 Volts).
NOTE
If you are using two positioners in series as e. g., working in split range, the resulting impedance will be
1.100 Ohms. Therefore, the analog output should be capable to handle a voltage drop of 22 Volts.
Connection of the FY301 in multidrop configuration should be done as in figure 1.12. Note that a
maximum of two positioners can be connected on the same line and that they should be connected
in series.

Air Supply Requirements
Before the air supply is connected to the positioner, we recommend the hose is opened freely for 2
to 3 minutes to allow any contamination to be blown out. Direct the air jet into a large paper towel to
trap any water, oil, or other foreign materials. If this indicates that the air system is contaminated, it
should be properly cleaned.
As soon as the positioner is connected and powered, internal air leakage will provide protection
against corrosion and prevent moisture inside. For this reason, it is strongly recommended to keep
the positioner pressurized as much as possible.
Recommendations for Instrument Air Supply System
Instrument air quality shall be superior to that of industrial compressed air. Humidity, suspended
particles and oil may impair the instrument operation, either temporarily or permanently in case of
internal parts wearing.
As per standard ANSI/ISA S7.0.01 - 1996 - Quality Standard for Instrument Air, instrument air shall
have the following characteristics:
Dew point 10°C below minimum instrument temperature
Size of particles (airborne) 40 µm (maximum)
Oil content 1 ppm w/w (maximum)
Contaminants free from corrosive flammable gases
This standard recommends that the compressor intake be located in an area free from process spills
and fitted with and adequate filter. It also recommends the use of non-lubricated type compressors,
in order to prevent air contamination by lubricating oil. Where lubricated type compressors are
adopted, there shall be used means to make the air oil free.
Figure 1.13 and 1.14 shows a typical system for air supply and air quality conditioning.

Recommendations for mounting Approved Equipments with the IP 66 W
certifications (use in saline atmospheres)
NOTE
This certification is valid for stainless steel positioners manufactured,
approved with the
certification IP 66 W. All positioner external material, such as gauge, plugs, connections etc.,
should be made in stainless steel.
The electrical connection with 1/2” – 14NPT thread must use waterproofing sealant. A non-
hardening silicone sealant is recommended.
The instrum
ent modification or replacement parts supplied by other than authorized
representative of Smar is prohibited and will void the certification.
Rotary and Linear Magnet
Magnet models are linear and rotary, for utilization on linear and rotary actuators.
