OPERATION & MAINTENANCE INSTRUCTIONS MANUAL FI302 F I 3 0 2 M E smar www.smar.com Specifications and information are subject to change without notice. Up-to-date address information is available on our website. web: www.smar.com/contactus.asp 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.

No See section 6 - Maintenance OK XI FI302 - Operation and Maintenance Instruction Manual XII Section 1 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. COVER LOCKING SCREW HOUSING ROTATION SET SCREW Figure 1.1 - Display lid locking screw The mounting bracket makes it easier to adjust the converter in several positions, as shown on Figure 1.2 – Mounting Positions and Dimensional Drawing 1.1 FI302 - Operation and Maintenance Instruction Manual ALLOW 150 MM MINIMUM FOR LOCAL ZERO AND SPAN ADJUSTMENT WITH MAGNETIC TOOL.

Electric Connection Output Connection To access the terminal block, loosen the cover locking screw to release it. Rotate the cover anticlockwise and remove it (See Figure 1.3). COVER LOCKING SCREW Figure 1.3 – Terminal Block Cover 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. If power fails, the outputs status will be uncertain and in case of communication loss, communication 1.2 Installation lacks, the outputs will move to fixed pre-configured values or to safety default values.

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. 1.3 FI302 - Operation and Maintenance Instruction Manual DCS/PLC Interface (LC700) DC Power Supply (see cargo line) Terminator Terminator DC barrier COMM C1 C2 Output 2 Equipment with 4 – 20 mA Input DC Power Supply (see cargo line) DC barrier For C1 and C2 C1 C2 The components inside the gray area are normally located in the control room Output 1 Equipment with 4 – 20 mA Input + 1 2 3 4 COMM. - + HART I.S.

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. Pair Single Shielding Yes Twisted Yes Size Maximum Length Type 0,75 mm² 1900 m A Multicables yes yes 0,32 mm² 1200 m B Multicables no yes 0,13 mm² 400 m C Multicables yes no 1,25 mm² 200 m D Table 1.1 – Types of Cables. 1.5 FI302 - Operation and Maintenance Instruction Manual 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. “A” TYPE CABLE Characteristic impedance on the 31,25 kHz frequency Maximum attenuation on the 39 kHz frequency Maximum capacitance outbalance for shielding Maximum DC resistance per conductor lenght Maximum propagation delay change Conductor transversal area 100 Ohm 20% 3 dB/km 2 nF/km 22 Ohm/km 1,7 us/km 0,75 mm2 Table 1.2 – “A Type” Cable Characteristics Total Cable Length 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. Trunk Terminator A Terminator B Spur 2 Spur 3 Spur 1 FY302 LD292 FI302 Figure 1.8 – Total Cable Length Segment A, B Trunk Length Spur 1 120 m Spur 2 40 m 240 m Spur 3 80 m Total 480 m 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.

Signal Isolator Isolates the data signal between the output and the CPU. Central Processing Unit (CPU), RAM and FLASH The CPU is the converter intelligent part, and is responsible for the management and operation of the blocks, auto-diagnosis and communication. The program is stored in FLASH memory. For the temporary storing of data there is a RAM. The RAM data will be lost if energy fails, although the device has a non-volatile EEPROM where the valid data are stored, as for calibration, configuration and identification. Communication Controller It controls the line activity, modulates and demodulates communication signals and inserts or delete initial and final delimiters. Power Supply Uses energy from the control loop to power the converter circuit. Power Insulation The power must be insulated as the output signals sent or received by the output 2.1 FI302 - Operation and Maintenance Instruction Manual Signal Conditioner Prepares the signals from the network or from the communication controller at acceptable levels by the communication controller or the fieldbus network, respectively. Display Controller Receives CPU data and controls the Liquid Crystal Display. Local Adjustment The power must be insulated once signals are sent and received by the output. 2.2 Section 3 OPERATION Liquid Crystal Display The liquid crystal display shows up to three variables that may be selected by the user. When two or three variables are chosen, the display will alternate the sampling from both with an interval of approximately 3 seconds. The LCD is made of a field with 4½ numerical digits, a field with 5 alphanumeric digits and an information field, as shown on Figure 3.1.

See Figure 3.2. The display shows the engineering units, values and parameters simultaneously with the majority of status indicators, depending on the local adjustment configuration. Figure 3.2 – Typical Monitoring Mode displaying the current inferior value, namely 4.0 mA. 3.1 FI302 - Operation and Maintenance Instruction Manual The monitoring mode is interrupted when the user makes the local adjustment. The display also shows messages and errors (See Table 3.1). DISPLAY DESCRIPTION Init , FI302 & Version The FI302 is powered and initiated Blk OOS OOS block not configured and link ineffective bad Communication or signal failure or bad signal Table 3.1 – Display Messages and Errors. 3.2 Section 4 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. 5.1 FI302 - Operation and Maintenance Instruction Manual FI302 - + 1 2 3 4 COMM. + - LOCK Power Power Supply Supply Ampere Meter Amperimeter P 30 mA I Figure 5.1 – Current Measuring Connection Diagram There are two ways to apply the trim: use a magnetic tool for one of them and a fieldbus configuration tool, like the Smar Syscon for the other. It is possible to calibrate the conveter by means of parameters CAL_POINT_LO and CAL-POINTHI. Let’s take the lower value as an example: write 4 mA or the lower value in parameter CAL_POINT_LO. This parameter indicates where the converter should be when the setpoint lower value is 0%. The desired value should be entered. Figure 5.2 - Calibrating the CAL_POINT_LO – FI302 5.2 Calibração Always keep in mind that, simply by writing in this parameter, the trim procedure is initialized. Read the current in the multimeter and write that value in parameter FEEDBACK_CAL. Write in this parameter until it reads 4.0 mA or the lower value readout of the multimeter. This parameter should be set with the actual output current during the calibration procedure. The value should be entered here. Figure 5.3 - Feedback of Current Lo Value In order to end the trim procedure, choice DISABLE in the parameter CAL_CONTROL. This parameter ends the calibration procedure. The enable option indicates that the calibration process is being done. In order to finalize its procedure, the user should set it to disable. Figure 5.4 - Closing the Calibration Lo Procedure Let’s take the upper value as an example: Write 20 mA in parameter CAL_POINT_HI. Always keep in mind that, simply by writing in this parameter, the trim procedure is initialized. 5.3 FI302 - Operation and Maintenance Instruction Manual This parameter indicates where the converter should be when the setpoint is 100%. The desired value should be entered. Figure 5.5 - Calibrating the Cal Point Hi – FI302 Read the current in the multimeter and write that value in parameter FEEDBACK_CAL. Write in this parameter until it reads 20.00 mA or the upper value readout of the multimeter. This parameter should be set with the actual output current during the calibration procedure. The value should be entered here. Figure 5.6 - Feedback of CAL_POINT_HI – FI302 In order to end the trim procedure, choice DISABLE in the parameter CAL_CONTROL. 5.4 Calibração This parameter ends the calibration procedure. The enable option indicates that the calibration process is being done. In order to finalize its procedure, the user should set it to disable. Figure 5.7 - Closing the Calibration High Procedure The calibration will be enabled only if the output of AO block has a valid value and status different of "Bad" In this case, the following message can be seen in the parameter XD_ERROR. This parameter indicates de Error Code Operation associated to calibration procedure. It indicates that the calibration procedure was not sucessfull. Figure 5.8- Calibration Error Message – FI302 5.5 FI302 - Operation and Maintenance Instruction Manual 5.6 Section 6 MAINTENANCE NOTE Equipment installed in hazardous atmospheres must be inspected in compliance with the IEC60079-17 standard. Diagnostic Block – DIAG This transducer block provides the following characteristics: Online measuring time for the functional blocks execution; Hardware revision Firmware revision Equipment serial number Main board serial number The BEHAVIOR parameter defines the initial parameter values that will be used after block instantiation. The Adapted option selects a group of initial values more proper for the parameters, thus avoiding invalid values. The Spec option also allows defining initial values. Troubleshooting Physical Inspection After connecting the FI302 to the network, if it loses communication or slows down. e.g., due to multiple tentative communication, the error may be caused by poor installation procedure, by the configuration or by poor equipment performance. Causes for communication errors Badly fit connections Installation problems, repeated equipment addresses, bad configuration, etc. Terminator located at the wrong place, with or without terminator Power supply with too low or unstable voltage value Too long or too many Spurs Wrong ground or no ground Water infiltration in the equipment due to connections with wrong sealing and/or loose clamps Low isolation After carrying out the procedures for detecting network defects, act as follows: Insulate the segment or equipment that causes the problem Check if the polarity is correct Check is the address is correct Check the the Network integrity Check if the tension on the converter terminals is at least 9.5 V during communication Remove the equipment to a bench and test it. If it presents malfunctioning, contact Smar. Parameters used for Troubleshooting The FI302Transducer Block parameters used for troubleshooting are: BLOCK_ERR, XD_ERROR, FINAL_VALUE, RETURN e BACKUP_RESTORE Caution messages may appear on the status of the Return parameter or Block Error parameter, in given circumstances such as presented below, in two modes, OOS and AUTO. BLOCK_ERR This transducer BLOCK_ERR parameter shows the following errors: Block Configuration – When XD_SCALE has an improper range or unit; 6.1 FI302 - Operation and Maintenance Instruction Manual Output Failures – When the loop current open; Out of Service – When the block is on out of service mode (OOS) Limit Conditions for Calibration Lower 3.99 < NEW_LOWER < 11.5 mA, otherwise XD_ERROR = 22 Upper 12.5 < NEW_UPPER < 20.01 mA, otherwise XD_ERROR = 22 FINAL_VALUE The desired current value and the status written by the AO block; RETURN Current output value coming from the AO block; RETURN STATUS The transducer block Return Status indicates the following errors: Bad::NonSpecific:NotLimited – When the loop current is interrupted (open loop); XD_ERROR – This parameter is used to indicate the calibration status; BACKUP_RESTORE This parameter is used as backup or to recover configuration data. Table 6.1 has the information to determine the converter or network failures. NOTE It is recommended not to repair printed circuit boards. Keep spare parts or buy them from Smar, if necessary. Symptom PROBABLE SOURCE OF ERROR Diagnostic Converter Fieldbus Connections Check power supply polarity and continuity No turn on Power Supply Check power supply output. The voltage at the FI302 terminal block must be between 9 and 32 Vdc Electronic circuit failure Check circuit boards for defects and replace them for spare ones. Network Connection Check equipment, power supply and terminator connections. Network equipment impedance Check power supply and terminator impedance. No communication Converter configuration Check the converter communication parameters setting Network Configuration Check the network communications settings Electronic Circuit Failure Replace the main board and the input board matched pairs. Output Terminal Connection Check power supply, channels, terminal box polarity and continuity Incorrect Outputs (the power supply indicated aside is for 4-20 mA equipments) Power Supply Check power supply output. The FI 302 output voltage must be between 3 and 45 Vdc. Load Resistance Must be between 0 and 2000 Ohm. The higher value depends on the output power supply voltage. Calibration Check the converter calibration 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.

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. Figure 7.3 - Configuring the Characterization Curve X points 7.2 Configuração Avançada This parameter defines the coordinates Y It is not necessary to follow any order. A monotone curve is allowed. FI2EM312 CDR Figure 7.4 - Configuring the Characterization Curve - Y points 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).

The option "update" should be selected in order to execute the upgrade of local adjustment programming tree. After its step all the parameters selected will be show on the LCD display. Figure 7.9 - Parameters for Local Adjustment Configuration 7.6 Section 8 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.
