INTRODUCTION
The FY303 is a Profibus PA 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
FY303 enabled the choice of several types of flow characterizations, an easy interface between the
field and the control room and several interesting features that considerably reduce the installation,
operating and maintenance costs.
The FY303 is part of Smar's complete 303 line of Profibus PA devices.
Some of the advantages of bi-directional digital communications are known from existing smart
transmitter protocols: Higher accuracy, multi-variable access, remote configuration and diagnostics,
and multi-dropping of several devices on a single pair of wires.
The system controls variable sampling, algorithm execution and communication so as to optimize
the usage of the network, not loosing time. Thus, high closed loop performance is achieved.
Using Profibus technology, with its capability to interconnect several devices, very large control
schemes can be constructed. In order too be user friendly the function block concept was
introduced.
The need for implementation of Fieldbus in small as well as large systems was considered when
developing the entire 303 line of Profibus-PA devices. They have common features and can be
configured locally using a magnetic tool, eliminating the need for a configuration tool or console in
many basic applications.
Get the best result of the FY303 by carefully reading these instructions.
NOTE
In case of using Simatic PDM as the configuration and parameterization tool, Smar
recommends that the user does not apply the option "Download to Device". This function
can improperly configure the field device. Smar recommends that user make the use of
the option "Download to PG / PC" and then selecting the Device Menu, use the menus of
the transducer, function and display blocks acting specifically, according to each menu
and method for reading and writing.
WARNING
Throughout the operation of the positioner, including self-setup, do not touch the moving parts of
valve/actuator/positioner assembly as they may unexpectedly move automatically. Make sure to disconnect
supply air before touching any moving parts.

Section 1
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 measurement and control depends on several variables. Although the
converter has an outstanding performance, proper installation is essential, in order to maximize its
performance.
Among all factors, which may affect converter accuracy environmental conditions are the most
difficult to control. There are, however, ways to reduce the effects of temperature, humidity and
vibration.
The FY303 has a built-in temperature sensor to compensate for temperature variations. At the field,
this feature minimizes the temperature variation effect.
Locating 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 avoided.
Use of sunshades or heat shields to protect the positioner from external heat sources should be
considered, if necessary.
Humidity is fatal to electronic circuits. In areas subjected to high relative humidity, the O-rings for the
electronics cover must be correctly placed. 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
humidity. The electronic circuit is protected by a humidity proof coating, but frequent exposures to
humidity may affect the provided protection. 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. Code approved sealing methods on conduit entering the positioner should be
employed.
Although the positioner is virtually insensitive to vibration, installation close to pumps, turbines or
other vibrating equipment should be avoided.
Mounting
The mounting of positioner FY303 will depend on actuator type, single (spring return) action or
double action and on actuator movement, if it is linear or rotary. Two supports are required for
mounting, one for the magnet and the other for the positioner itself. Smar may supply them both
since they are specified in the order code.
Rotary Movement
Install the magnet on the valve stem using the magnet support (See Figure 1.2).
Install the positioner support on the actuator. The actuator should be in accordance with standard
VDI/VDE 5845, all you have to do is tighten the four screws with the lock washers on the standard
support.
For special supports, refer to specify instructions. After installing the support on the actuator, it is
possible to mount the positioner FY303 on the support by means of the four screws with lock
washers.
Make sure that the arrow engraved on the magnet coincides with the arrow engraved on the
positioner when the valve is in mid travel.
If the installation of the positioner or magnet should be altered, or if there should be any other
modification, the positioner will require a recalibration.
As to the type of valve action, refer to paragraph "Pneumatic Connections".

FY303 - Operation, Maintenance and Instructions Manual
1.2
Linear Movement
Install the magnet on the valve stem using the magnet support (See Figure 1.3).
Install the positioner support on the actuator. The actuator support may be secured in place as per
standard NAMUR/IEC 536-4 or in accordance with user specified boring. Install the positioner on the
support and tighten the four screws in the threaded bores located on the side opposite to the
pressure gages (See Figure 1.3). Use lock washers in order to prevent screw slackening.
Make sure that the support is not obstructing the exhaustion outlets.
NOTE
Make sure that arrow engraved on the magnet coincides with the arrow engraved on the positioner when the
valve is in mid travel. The magnet mounting in relation to the hall sensor:
1. Must not have attrition between the internal magnet face and the hall sensor salience during the travel
(rotary or linear), through the magnet.
2. The magnet and the salience of hall sensor must not be distant.
A minimum distance of 2 mm and a maximum distance of 4 mm is recommended between the magnet external
face and the positioner face. For that, a centralizer device (linear or rotary) must be used. The centralizer
device is in the positioner packing.
If the installation of the positioner or magnet should be altered, or if there should be any other
modification, the positioner will require a recalibration.
Pneumatic Connections
Air supplied to the positioner FY303 shall be quality instrument air, i. e., dry, clean and non-
corrosive. Refer to the American National Standard. “Quality Standard for Instrument Air” (ANSI/ISA
S7.0.01 - 1996).
The FY303 is supplied with input and outputs air filters; but these filters do not substitute a
preliminary instrumentation air treatment. We recommend a periodic cleaning of such filters each 6
months or less, case the air instrument quality is not good.
Air supply pressure to the FY303 shall be between 1.4 bar (20 psi) and 7 bar (100 psi). In case such
requirements can not be fulfilled, the use of an air pressure regulator is acceptable.
Use sealant on threads. Sealants like PTFE (Teflon) tape shall be avoided because they may
fragment and eventually obstruct internal parts.
Positioner FY303 may be supplied with pressure gages. There are taps available for IN, OUT1 and
OUT2. Before connecting the pressure gages, make sure that all lines be completely purged.
Valve positioner FY303 has two pneumatic outputs. They work on opposite directions to open or
close the valve.
WARNING
The FY303 should fail, for example, because of a power failure. The output identified as OUT1 (output 1)
goes to nearly zero; while the output identified as OUT2 (output 2) goes to nearly the air supply pressure.
Pneumatic connections are identified as IN (input) for the air supply, and OUT1 and OUT2 for
Output 1 and Output 2 respectively. Use 1/4 NPT connections. Sealant may be used NPT threads.
Connect the air supply tubing to the connection identified as IN. Make sure that the air supply
pressure does not exceed the maximum rating accepted by the positioner or actuator. The tubing
used to connect the positioner FY303 to the actuator shall be as short as possible. The manometer
supply is optional.
NOTE
When ordering the positioner in stainless steel 316, combined with the local pressure gauges, the gauge
case is in SS 316. For wet parts and threads in SS 316, please, consult Smar.
ATTENTION
Make sure that sealant does not enter the positioner.
There are six exhaust outputs in the FY303, all of them fitted with filters. It is very important that
such outputs are neither blocked nor obstructed, because the air must circulate freely.
All filters shall be inspected to make sure they will not obstruct the outputs (Refer to Section 4 -
Maintenance Procedures).

Installation
1.3
Double Action - Air to Open (Fail Close)
Connect Output 1 (OUT1) of the positioner to the input identified as OPEN in the actuator, and
connect Output 2 (OUT2) of the positioner to the input CLOSE in the actuator.
Double Action - Air to Close (Fail Open)
Connect Output 2 (OUT2) of the positioner to the input identified as OPEN in the actuator, and
connect Output 1 (OUT 1) of the positioner to the input CLOSE of the actuator.
Single Action
Connect Output 1 (OUT1) of the positioner to the input of the actuator. Use a plug to block Output 2
(OUT2).

Electronic Housing Rotating
The electronic housing can be rotated in order to have a better position of the digital display. To
rotate it, use the Housing Rotation Set Screw. (See Figure 1.4).
The local indicator itself can also be rotated. (See Figure 2.4).
Electric Wiring
Reach the wiring block by removing the Electrical Connection Cover. This cover can be locked by
the cover locking screw. To release the cover, rotate the locking screw clockwise.
The wiring block has screws on which fork or ring-type terminals can be fastened.
Figure 1.4 - Cover Locking and Housing Rotation Set Screw
For convenience there are two ground terminals: one inside the cover and one external, located
close to the conduit entries. (See Figure 1.5).
Figure 1.5 - Wiring Block
The FY303 uses the 31.25 kbit/s voltage mode option for the physical signaling. All other devices on
the same bus must use the same signaling. All devices are connected in parallel along the same
pair of wires.
Various types of Profibus devices may be connected on the same bus.

Installation
1.7
The FY303 is powered via the bus. The limit for such devices is according to the DP/PA coupler
limitations for one bus for non-intrinsically safe requirement. In hazardous area, the number of
devices may be limited by intrinsically safe restrictions, according to the coupler DP/PA and barriers
limitations.
WARNING
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 moisture 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
screw.
In hazardous zones with intrinsically safe or non-incentive requirements, the circuit entity parameters and
applicable installation procedures must be observed.
Cable access to wiring connections is obtained by the two conduit outlets. Conduit threads should be sealed
by means of code-approved sealing methods. The unused outlet connection should be plugged and sealed
accordingly.
Should other certifications be necessary, refer to the certification or specific standard for installation
limitations.
The Figure 1.6 - Conduit Installation Diagram shows the correct installation of the conduit, in order
to avoid penetration of water, or other substance, which may cause malfunctioning of the
equipment.
WIRES
CORRECT INCORRECT
Figure 1.6 - Conduit Installation Diagram
The FY303 is protected against reverse polarity, and can withstand ±35 Vdc without damage, but it
will not operate when in reverse polarity.
Topology and Network Configuration
Bus topology (See Figure 1.7) and tree topology (See Figure 1.8) are supported. Both types have a
trunk cable with two terminations. The devices are connected to the trunk via spurs. The spurs may
be integrated in the device giving zero spur length. A spur may connect more than one device,
depending on the length. Active couplers may be used to extend spur length.
Active repeaters may be used to extend the trunk length.
The total cable length, including spurs, between any two devices in the Fieldbus should not exceed
1900m.
The connection of couplers should be kept less than 15 per 250m. In following figures the
DP/PA link depends on the application needs.

Intrinsic Safety Barrier
When the Fieldbus is in an area requiring intrinsic safety, a barrier must be inserted on the trunk
between the power supply and the DP/PA coupler, when it is Non-Ex type.
Use of SB302 is recommended.
Jumper Configuration
In order to work properly, the jumpers J1 and W1 located in the FY303 main board must be correctly
configured.
J1 This jumper enables the simulation mode parameter in the AO block.
W1 This jumper enables the local adjustment programming tree.

Installation
1.9
Power Supply
The FY303 receives power from the bus via the signal wiring. The power supply may come from a
separate unit or from another device such as a controller or DCS.
The voltage should be between 9 to 32 Vdc for non-intrinsic safe applications.
A special requirement applies to the power supply used in an intrinsically safe bus and depends on
the type of barrier used.
Use of PS302 is recommended as power supply.
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 bag 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 started, internal air leakage will provide protection
against corrosion and prevent the ingress of moisture. For this reason, the air supply pressure
should always be kept on.
Recommendations for an Instrument Air System
Instrument air quality shall be superior to that of industrial compressed air. Humidity, airborne
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.
The figures 1.9 and 1.10 show a typical system for air supply and air quality conditioning.

Remote Hall Sensor
The remote Hall magnetic sensor is an accessory recommended for high temperature and extreme
vibration applications. It prevents excessive wear of the equipment and, consequently, the reduction
of its useful time.

Installation
1.11
Figure 1.14 - Remote Hall Sensor
The electric signals on the remote sensor’s connection to que equipment are of low intensity.
Therefore, when installing the cable inside the conduit (maximum limit 20 meters length) keep it
away from possible sources of induction and/or magnetic interference. The cable supplied by Smar
is shielded for excellent protection against electromagnetic interference, but despite this protection
avoid the cable sharing the same conduit with other cables.
The connector for remote Hall sensor is easy handling and simple installation.
See the installation procedure:
