Introduction
INTRODUCTION
The FI302 is part of Smar´s first generation of FOUNDATION™ fieldbus field equipment. It is a
converter intended to connect Foundation Fieldbus systems with actuators and positioners for 4 -20
mA control valves. The FI302 produces a 4 -20 mA output proportional to the input received by the
Fieldbus network. Its digital technology enables an easy interface between the field and the control
room, while offering several types of transference functions and interesting features that reduce
installation, operation and maintenance costs.
Foundation Fieldbus is a digital communication system that enables distributing control functions for
field equipment and advantageously replaces conventional technology.
Other protocols only disclose maintenance data, as they were not devised for control data. The main
Fieldbus goal was to overcome this situation. Closed loop control with a 4 -20 mA performance
requires high speed, which means higher power consumption – a feature that is not compatible with
intrinsic safety. This fact led to the use of a moderately high communication speed and to devise a
system with a minimum communication capability. Using scheduling synchronization, the system
controls variable sampling, algorithm execution and communication. The network treatment is
optimized and high circuit loop performance is achieved.
Using Foundation Fieldbus Technology with its capability to interconnect several devices, very large
projects can be constructed. The function block concept allows the user to easily construct the
programming and overview complex control strategies (Smar CD600 users are familiar with this
concept, since it was implemented a few years ago). Another advantage is flexibility, as the control
strategy may be edited without having to rewire or change any hardware.
The FI302 and the Smar FOUNDATION™ fieldbus family have function blocks that avoid the need for
separate equipment and facilitate implementing the control strategy. Among these function blocks,
the following may be enhanced: PID controller, Input Selector, Arithmetic, Signal Characterizer and
Integrator. These built-in blocks improve control, reduce communication, dead-time and costs.
Any FOUNDATION™ fieldbus equipment with Master Backup rapidity may work as a network master
and be locally configured using a magnetic screwdriver in several situations. This tool eliminates the
need for a configurator in many basic applications.
Read carefully these instructions to get the best result from the FI302.

will be included in the following editions. Suggestions for their improvement are welcome.
Warning
For more objectivity and clarity, this manual does not contain all the detailed information on the
product and, in addition, it does not cover every possible mounting, operation or maintenance
cases.
Before installing and utilizing the equipment, check if the model of the acquired equipment complies
with the technical requirements for the application. This checking is the user’s responsibility.
If the user needs more information, or on the event of specific problems not specified or treated in
this manual, the information should be sought from Smar. Furthermore, the user recognizes that the
contents of this manual by no means modify past or present agreements, confirmation or judicial
relationship, in whole or in part.
All of Smar’s obligation result from the purchasing agreement signed between the parties, which
includes the complete and sole valid warranty term. Contractual clauses related to the warranty are
not limited nor extended by virtue of the technical information contained in this manual.
Only qualified personnel are allowed to participate in the activities of mounting, electrical connection,
startup and maintenance of the equipment. Qualified personnel are understood to be the persons
familiar with the mounting, electrical connection, startup and operation of the equipment or other
similar apparatus that are technically fit for their work. Smar provides specific training to instruct and
qualify such professionals. However, each country must comply with the local safety procedures,
legal provisions and regulations for the mounting and operation of electrical installations, as well as
with the laws and regulations on classified areas, such as intrinsic safety, explosion proof, increased
safety and instrumented safety systems, among others.
The user is responsible for the incorrect or inadequate handling of equipments run with pneumatic
or hydraulic pressure or, still, subject to corrosive, aggressive or combustible products, since their
utilization may cause severe bodily harm and/or material damages.
The field equipment referred to in this manual, when acquired for classified or hazardous areas, has
its certification void when having its parts replaced or interchanged without functional and approval
tests by Smar or any of Smar authorized dealers, which are the competent companies for certifying
that the equipment in its entirety meets the applicable standards and regulations. The same is true
when converting the equipment of a communication protocol to another. In this case, it is necessary
sending the equipment to Smar or any of its authorized dealer. Moreover, the certificates are
different and the user is responsible for their correct use.
Always respect the instructions provided in the Manual. Smar is not responsible for any losses
and/or damages resulting from the inadequate use of its equipments. It is the user’s responsibility to
know and apply the safety practices in his country.

INSTALLATION
General
NOTE
The installation carried out in hazardous areas should follow the recommendations of the IEC60079-14 standard.
The FI302 is a high end device and thus, in order to take advantage to its maximum, the FI302
requires an appropriate installation.
Many factors may affect the converter accuracy, among which environment conditions are the most
difficult to control. In order to reduce the effects from temperature, humidity and vibration, avoid its
installation in aggressive areas.
The effects from temperature variation may be minimized by assembling the converter in areas
protected from weather changes. If necessary, use thermal insulation against external heat sources.
Humidity is harmful to the electric circuits. In areas with high relative humidity levels, the correct
placing of the housing cover o-ring must be assured and hand-tight shut to press the o-ring. The
housing cover should not be removed on the field so that its threads are not damaged, as they are
not protected by painting.
A flexible sealing material should be applied on the electric connections to avoid humidity. See
details on how to connect the FI302 to Fieldbus.
Mounting
The display may be rotated at 90º to 90º angles for easier visualization. See figure 6.2 on section 6
– Maintenance. To access the display, unlock the locking screw on the display cover by rotating it
clockwise. See figure 1.1 to locate the locking screw.

The housing has two threaded openings where to insert the signal cables of the connection terminal
block. The threads allow connecting the wiring conduit or the cable gland.
For more convenience, there are three ground terminals: one internal and two externals close to the
terminal block.
Figure 1.4 shows the three terminals of the converter current output channels, which are marked
with numbers 1, 2 and 3. Terminal 4 is the power supply common ground to the loop controlled by
the channels. The converter H1 (IEC-61158-2) power supply must be connected to the terminals
marked by (+) and (-).
The current output is limited by the power supply voltage on the current loop and by the conditions
of the classified area. Refer to the load curve to determine the maximum equipment quantity allowed
for the bus.

Connecting the FI302 to the FOUNDATION™ fieldbus
The FI302 may be connected to or removed from a fieldbus network in operation. Take due
precaution with this operation and prevent signal cables from touching the shielding, the ground
cables or one another. Insert the FI302 on the network with communication speed equal to its own
(31,25 kbps), FOUNDATION™ fieldbus protocol.
Preparing the FI302 before connecting it to network
The FI302 may be configured on-line or off-line by a fieldbus configuration like the Smar SYSCON
installed on a Engineering station, for instance.


Then, use the configuration device to attribute a tag to the converter, using the “Assign Tag”
option on the menu.
Download the configuration for the equipment or for the entire network.
NOTE
The Assign Tag may be applied on-line or off-line for specific equipment connected to a fieldbus network
with other equipments.
ATTENTION
To attribute a new Tag to the equipment, the system configuration must be changed. This may bring some
inconveniences on the control configuration. For example, the addressees configured on the previous
functional blocks and links are deactivated. Therefore, if the tags are modified, the entire configuration must
be revised and when applicable, the TAG list from OPC Servers shall be updated.
The FI302 is protected against reverse polarity and may support ±35 VDC without causing any
damage, but it will not work under these conditions. Although the FI302 cannot be affected by
polarity, try and keep the polarity in all connections.
In hazardous areas, the number of equipments is limited by the intrinsic safety restrictions. Consult
the documents related to the use of equipment for this area.

segment. An independent power supply shall be used to power the 4 – 20 mA equipments
connected to the converter output.
Low current consumption equipments should be used for intrinsically safety applications. Choose
low resistance cables to reduce drop in voltage on the junction box and on each equipment.
Terminator
The terminators are impedances with the same values as the specific bus impedance to avoid signal
reflection and, consequently their distortion or loss. Each bus segment must have only two
terminators positioned on its ends. Some equipments, especially for power source, output/input,
fieldbus test or PC simulation card, etc, include the option for an internal terminator connection.
Before connecting a terminator to the bus, check if the equipment already has an internal terminator
on one end, and install the other terminator.
Each terminator has a 100 Ohm impedance and the equivalent impedance of both will be 50 Ohm.
The terminator causes a 250- to-500 mV amplitude tension drop on the bus.
Smar has the terminator model BT302.
Cabling
The FOUNDATION™ fieldbus protocol works with several types of cable and the best they are, the
longer the lengths and the greater the number of equipments to be connected to it. Table 1.1 shows
the regular cable types used when installing FOUNDATION™ fieldbus equipments and their
characteristics.

NOTE
The length of non-twisted cables decreases regardless of their diameter and shielding (see D type data). It
is recommended not to use these cables, but if you do, do not leave them too close to power cables or noisy
equipments.
The Fieldbus Foundation recommends the “A” type cable. Table 1.2 shows its main characteristics
for a bus project.

The cable(s) total length vary (ries) according to its/their quality. The total length is the sum of the
trunk and the spur lengths. For instance, use the diagram on figure 1.8 and the table 1.3 to
determine the total length of a hypothetical bus.

Table 1.3 – Examples of Total Cable Lengths
The cable types should combine according to the equation below:
L1 / L1max + L2 / L2max + … < 1
Example: the network has the following cables:
L1: is the type 1 cable length
L2: is the type 2 cable length
L1max: is the type 1 maximum cable length (see table 1.1).
L2max: is the type 2 maximum cable length (see table 1.1).
1.6
Installation
L1 = 1000 m of A type cable
L2 = 100 m of B type cable
1000 / 1900 + 100 / 1200 = 0,61
The hypothetical combination on last example satisfies the above equation: 0,61 < 1
Cable shielding
Shielding must be used, especially at noisy sites with high EMI/RFI near to the bus. Connect the
spur shielding with the trunk shielding. The shielding should cover a minimum 90% cable length to
guarantee good protection.
Grounding
The shielding is grounded only at the power supply negative terminal. Do not ground it at the other
terminal, in order to avoid a secondary current circulation that could induce noise onto the bus. If the
cable is not shielded install it on a tray and ground it only at one end. Do not use shielding as power
conductor. Signal cables should NOT be grounded.
Commissioning
This item will explain the commissioning related to the configuration of the converter in the network.
Before receiving or installing the converter and after the plant’s detailing project conclusion, it is
suggested to initiate the offline configuration. Once accompli shed those steps proceed with the
device configuration download.
In FOUNDATION™ fieldbus the database configuration is made on user-defined tags with no
association with the physical devices. Therefore, the devices must be associated to their respective
configurations.
Each device has a unique Device ID with 32 characters as hardware address, and meant to
distinguish a device from another. This address is engraved on the circuit board by the manufacturer
and cannot be changed. A field device is associated to its configuring system when correlates its
configuration tag to the device ID. If the factory tag is identical to the configured tag on the
configuring systems they will be automatically associated by the configurator system. Once it is
connected to the network, the factory tag may be named, if not done yet.
When all the devices are associated to their respective tags, the configuration may be completely or
partially unloaded on the network equipments.
If possible, use the configuring system to simulate the control and the operation. Then, you may
start, stop and go through the control strategies and check if the plant is operating normally before
the start-up.
Commissioning stages



Connect the electrically converter to the segment, so that the fieldbus will recognize it as an
equipment with a non-commissioned tag;
Use the configuration software to instantiate the newly-connected equipment. This creates ties
between the physical equipment in the plant and the database configuration;
Upload the equipment internal data on the configuration system and its strategy control on the
equipment.
NOTE
The Fieldbus requires that the measuring unit be the same, both on the equipment transducer block and the
function blocks, in order to avoid commissioning error.
Use of non-preconfigured to devices
Devices with non-configured tags are configured during commissioning. To do it, follow the
procedure:




Connect each adequate equipment to a fieldbus segment. The system will recognize them as
non-commissioned equipments;
Instantiate each equipment on the adequate segment in the configuration software;
Name a TAG to the specific device according to the plant process flowchart (P&ID);
Download the configuration to the equipment.
1.7
FI302 - Operation and Maintenance Instruction Manual
Use of preconfigured equipments
The devices with preconfigured tags identify themselves automatically with the configuration and
save commissioning time. The user must simply install them and check when they appear on the
system configurator screen.
Each preconfigured device must be installed on the specific plant site where it was configured for.
Linking Device
The linking device, for instance, the Smar DFI302 or other interface, addresses all the devices on
each network automatically. For practical purpose, the node address may be hidden, once it is not
of interest to most users, whose interaction is based on tags. However, the node address is typically
shown on the live list for the use of specialists. As a result, the Foundation Fieldbus devices may be
commissioned directly from the control room. Once the device is connected to the network it will be
detected in seconds. The devices may be connected or disconnected at any time without disturbing
the network.
Error monitoring and detection with Live List
If the device does not appear on the configuration system live list, it most probably was connected to
the wrong network or was not commissioned. In this case, it may be located in the live list of the
others networks. Another possibility is that the device cable is not connected or the device is not
operating properly. The live list, thus, is an excellent commissioning tool, as it facilitates checking
the cable connection to the field devices. To make sure that a device was not mistaken for another
on the same network or that it was installed at the wrong place, the device may be disconnected
temporarily from the network, so that the user check if the right tag disappears from the live list.
For more safety, use the configuration system to obtain detailed ID information from any device
connected to the network. This information helps checking the tag, the description, the
manufacturer, the type, the version and instrument general condition in order to confirm if it is the
right device and if it is working properly.

CONFIGURATION
The FI302 may be configured by any Foundation Fieldbus configuration tool or by an operational
console.
The FI302 has three output transducer blocks, one resource block, one display block, one
diagnostic block and other instant able function blocks.
This manual deals with the parameters of transducer blocks, display block and diagnostic block. The
function blocks are described in the specific function block manual.
Transducer Block
The transducer block insulates the hardware input/output function block like sensors and actuators.
The transducer blocks controls the input and output access through the specific manufacturer
implementation.
Usually, transducer block execute linearization function, characterization.
The connection between the transducer block and function blocks is called channel.
How to Configure a Transducer Block
When instantiating the FI302 on the configuration tool, the transducer block is automatically
instantiated.
The Transducer block has an algorithm, an internal parameter group and a channel that connects it
to the analog output function block.
The algorithm describes how the transducer transfers information from the hardware input/output to
other function blocks. The internal parameters, which cannot be linked to other blocks and published
on the link via communication, define the user interface for the transducer block. They are divided in
Standards that comply with the Foundation Fieldbus standard and those specified by manufacturers
and made according to their needs.
Every standard routine (e.g. calibration) follows a step by step method, which defines generally the
rules that will help the user.
The transducer, display and diagnostic blocks have several parameters that could be configured.
Here will treat of the most usual. The others are similar.
NOTE
The parameters ending with an “n” mean that they are the same for the other groups, and are distinguished by
their group number instead of the letter “n”.
For the FI302 basic configuration, use the Transducer and Display blocks parameters.
The Transducer Block parameters are configured as follows:
MODE_BLOCK
The MODE-BLOCK parameter configures the transducer block mode of operation. There are two
options: Out of Service or AUTO (automatic).
TERMINAL_NUMBER
The TERMINAL_NUMBER parameter relates a value for the channel. It starts with 1 to the
transducer number 1 and goes up to 3 to the transducer number 3. The FI302 has 3 current
channels and the current value will be sent internally to a specific transducer output from the analog
output function block. The number of the analog output block (AO) is related to the transducer
terminal number (TERMINAL_NUMBER). The channels with numbers 1, 2, 3 correspond to the
terminal block numbers 1, 2, 3. Select the combinations (1 - 1), (2 - 2), (3 - 3) for the channel and
the terminal block number where the output will occur (channel number – terminal block number).
The TERMINAL_NUMBER parameter chooses which of the three terminals of the terminal block will
supply the output. At least one of them must be chosen or otherwise the FI302 will issue the error
message “Blk_error”.
4.1
FI302 - Operation and Maintenance Instruction Manual
Display Block
The FI302 display block shows the variable chosen on monitoring mode or the option menu on the
local adjustment mode.
The display block is default-configured to make it possible to adjust the Upper Trim (UPPER) and
the Lower Trim (LOWER), to monitor the input transducer output and check the Tag.
The options of the FI302 local adjustment tree may be entirely configured by any fieldbus
configuration tool. Use them for the configuration, but for certain operations the local adjustment is
easier and faster, because it does not depend on network and communication connections. The
parameter options to work with the local adjustment are: Mode Block, Output Monitoring, Tag
Visualization and Tuning Parameter Adjustments.
Before using the magnetic tool for local adjustment, use the fieldbus configuration tool to prepare
the parameters that enable this operation.
How to Configure a Display Block
There are seven parameter groups indexed to the Block_Tag_Param_n parameter that may be
preconfigured by the user to enable a configuration by local adjustment. If it is not necessary to
display this group of tag-indexed parameters, write an invalid tag for the Block_Tag_Param_n
parameter. With this procedure the equipment does not recognize it as a valid parameter nor the
parameters indexed to it.
The Display Block parameters are configured as follows:
MODE_BLOCK
The configuration is identical to the previous transducer block.
BLOCK_TAG_PARAM_n
The is the block tag where the parameter belongs. The FI302 enables inserting up to 7 block tags.
Use a maximum of 32 characters.
INDEX_RELATIVE_n
This is the index related to the parameter that will be activated or visualized (0, 1, 2…6). See the
Function Block manual to know the required indices, or visualize them on the configuration tool by
opening the desired block. The FI302 accepts up to 7 parameter indices, configuring up to 7
parameter in the LCD.
DISPLAY_REFRESH
This parameter updates the new configuration.
4.2
Section 5
CALIBRATION
If necessary, it is possible to adjust the FI302 output channel current. The trim adjustment is used if
the indication on the transducer block output is different from the reference standard adopted.
Possible causes are:


The user Amperemeter is different from the plant standard.
The converter had its default characterization altered by overload or by the time of use.
To analyze the transducer output calibration, measure the channel output current with an accurate
Amperemeter and compare it with the indication on the FI302. Adjust the trim in case of difference.
The trim may be adjusted in two levels:
Lower Trim: At the range lower level.
Upper Trim: At the range upper level.
These points define the linear output characteristics. The trim adjustments are independent.
The Transducer Block parameters used for the FI302 calibration or current Trim are:
CAL_POINT_HI, CAL_POINT_LO, FEEDBACK_CAL e CAL_CONTROL.
Parameter description:
CAL_POINT_HI
This parameter configures the calibration range upper value.
CAL_POINT_LO
This parameter configures the calibration range lower value.
FEEDBACK_CAL
This is the current measured value used by the calibration method. It is used to apply the current
trim. To apply the lower or upper values, write the value read by the amperemeter in the parameter
during the calibration of the values. Repeat this operation until the measure is the same as the value
read. See figure 5.1.
CAL_CONTROL
It enables and disables the calibration process with options Enable and Disable. After initiating the
calibration method, the CAL_CONTROL parameter is used to return to the previous normal
operation.
The calibration will be enabled if the AO block output has a valid value and the status is different
from “Bad”. If “Bad” appears, the message “Calibration Failed” will appear on the XD_ERROR
parameter.
Figure 5.1 shows how to connect the converter to calibrate its lower value on 4 mA and its upper
value on 20mA.

Table 6.1 – Failure Diagnostic.
6.2
Maintenance
If the failure is not on table 6.1 use the Factory Init. The note below shows how to do it.
NOTE
Use factory init as the last option to recover control over the device when it presents problems related to
function blocks or the communication. Only authorized personnel should do it and the converter must
be offline. This procedure will enable the standard configuration values of the plant and disable the
previous equipment configuration.
To access the letters S and Z use two magnetic screwdrivers and loosen the screw that holds the
identification plate.
Proceed as follows:
1) Turn off the equipment and insert the magnetic screw drive handles in the openings S and Z and leave
them there;
2) Power the equipment;
When the display shows factory init, remove them and wait for the “S” symbol on the right upper corner
to unlit, indicating the end of the operation.
After running the factory init, download partially the configuration, which characterizes the equipment
functional behavior on the fieldbus.
Disassemble Procedure
See Figure 6.1 for guidance on this procedure. Turn off the power supply before disassembling the
converter.

ADVANCED CONFIGURATION
The transducer block allows some configurations through the parameters below that alter the
current output curve.
Parameter description
CHARACTERIZATION_TYPE
Indicates the characterization curve type;
CURVE_BYPASS
Enables and disables the characterization curve;
CURVE_LENGHT
Indicates the number of points the characterization curve;
CURVE_X
Characterization curve input points;
CURVE_Y
Characterization curve output points;
Characterization Curve
The transducer block also has a characterization curve, used to give a determined profile to the
output. This is useful, for example, when the FI302 controls a valve with a non-linear feature. The
characterization curve is applied to the input signal before being converted and sent to the analog
output by the transducer.
The CURVE_BYPASS parameter determines if the curve will be used or not. If the parameter is a
true Bypass, the curve is not used and the input value is transmitted directly to the output current
conversion routine.
"True" means that the
Characterization
Curve will be
bypassed.
This value "False"
enables the
Characterization Curve.
Figure 7.1 - Enabling the Characterization Curve
The characterization curve has 8 points. Each point has two coordinates (X and Y). These two
coordinates define the point location in the X – Y space, and the connection of adjacent points with
a linear segment forms the characterization curve. Extreme points are extrapolated.
7.1
FI302 - Operation and Maintenance Instruction Manual
This parameter
determines the
number of points valid
and configured.
The maximum number of
points is 8.
Figure 7.2 - Setting the Characterization Curve Length
These points are numbered from 1 to 8 and are contained in the CURVE_X (abscissas) and
CURVE_Y (ordinates) parameters. CURVE_X parameter requires points in crescent order, meaning
that the subsequent points must be greater than the preceding ones, or the parameter will not be
accepted. CURVE_Y parameter does not require this, and a non-monotonic curve is allowed.
NOTE
When writing on CURVE parameters remember to place the point coordinates in the correct order.
This parameter
defines the
coordinates X
The values should be
configured in crescent
order.

The Display Block allows configure up to three variables her they be shown in the digital indicator,
or a tree with parameters that can be altered via local adjustment. This configuration is possible
through procedures below:
NOTE
The parameters with “n” at its end mean that they are the same for other groups and are differentiated by their
group number instead of the letter.
The Display Block parameters are:
SUB_INDEX_n, MNEMONIC_n, INC_DEC_n, DECIMAL_POINT_NUMBER_n e ACCESS_n
SUB_INDEX_n
To visualize a tag choose the relative index equal to zero and the sub index equal to 1
MNEMONIC_n
This mnemonic identifies the parameter (16 characters maximum). Preferably, choose the
mnemonic with up to 5 characters because it will be not necessary to rotate it on the display.
INC_DEC_n
It is the increase and the decrease in decimal units when the parameter is Float, Float Status, or
Integer when the parameter is expressed in total units;
DECIMAL_POINT_NUMBER_n
Number of digits after the decimal point (0 to 3 decimal digits);
ACCESS_n
On Monitoring, the parameter enables only this option and on Action the function shows on the
display the increment and decrement values.
Definition of Parameters and Values
Block_Tag_Param
This is tag of the block to which the parameter belongs. Use up to a maximum of 32 characters.
Index_Relative
This is the index related to the parameter to be actuated or viewed (0, 1, 2…). Refer to the Function
Blocks Manual to know the desired indexes, or visualize them on the SYSCON by opening the
desired block.
In case you wish to visualize a certain tag, opt for the index relative equal to zero, and for the subindex equal to one (refer to paragraph Structure Block in the Function Blocks Manual).
Sub_Index
7.3
FI302 - Operation and Maintenance Instruction Manual
This is the mnemonic for the parameter identification (it accepts a maximum of 16 characters in the
alphanumeric field of the display). Choose the mnemonic, preferably with no more than 5 characters
because, this way, it will not be necessary to rotate it on the display.
Inc_Dec
It is the increment and decrement in decimal units when the parameter is Float or Float Status time,
or integer, when the parameter is in whole units.
Decimal_Point_Numb.
This is the number of digits after the decimal point (0 to 3 decimal digits).
Access
The access allows the user to read, in the case of the “Monitoring” option, and to write when "action"
option is selected, then the display will show the increment and decrement arrows.
Alpha_Num
These parameters include two options: value and mnemonic. In option value, it is possible to display
data both in the alphanumeric and in the numeric fields; this way, in the case of a data higher than
10000, it will be shown in the alphanumeric field.
In option mnemonic, the display may show the data in the numeric field and the mnemonic in the
alphanumeric field.
In case you wish to visualize a certain tag, opt for the index relative equal to zero, and for the subindex equal to one (refer to paragraph Structure Block in the Function Blocks Manual).

LOCAL ADJUSTMENT
When using the local adjustment for calibration, configure the display block to show the following
parameters: CAL_POINT_HI (UPPER mnemonic), CAL_POINT_LO (LOWER mnemonic) and TAG
(TAG mnemonic).
The FI302 has three output transducers, although only the number 1 leaves Smar with factory
configuration. To configure the other transducers to work with local adjustment use the configuration
tool.
NOTE
The Trim mode is removed from local adjustment automatically if the magnetic tool is not used during
approximately 16 seconds.
Under its identification plate, the FI302 has two openings marked with S and Z at their side, giving
access to two Reed Switch magnetic tools. They are activated when the magnetic tool is inserted in
the orifices by its handle (See Figure 8.1).
The magnetic tool permits adjusting most block parameters.
Figure 8.1 – Local Adjustment Orifices.
Jumper Configuration
J1 and W1 Jumpers located on top of the main board must be coupled with the main board and the
converter must have a display to show the local adjustment options.
Table 8.1 shows the possible actions applied on openings S and Z when the local adjustment is
enabled.

Returning Materials
Should it be necessary to return the converter to Smar, simply contact your local Smar office
informing the defective equipment serial number and dispatch it to our factory.
For easier analysis and faster solution of the problem, the returned material should include the
documentation with a description of the failure observed in the field and the circumstances that
caused it. Other information, such as the installation site, type of measure taken and the process
conditions are also important for a prompt evaluation.
