Safety Summary

GENERALWARNINGS

Units marked with EN-BC-606 must have alignment keys (AMP P/N

58327-1 Inter-Contact Plug) installed between contacts 15(S) and16(T) of the pre-terminated cable.

Improperly set DIP switches may result in equipment damage.Please read the instructions carefully before making connections or

applying power.

When voltage inputs are routed to the ()ASI02 or IMFBS01 slavemodules, the high impedance input will retain the signal in the event

of an open circuit. Bleeding resistors must be installed if timely badquality alarming is desired.

OVERVIEW

I-E96-443-1D 1 - 1

SECTION 1 - INTRODUCTION

OVERVIEW

This instruction is divided into 4 major sections, coveringoperation, installation, calibration. and troubleshooting of the

Analog Input Termination Assembly (NRAI0_). Each topic within these sections is divided into sub-sections with infor-mation specific to a particular application.

The analog input termination assembly is available in severa variations. The symbol _ (underscore) is used when referring toa feature that is common to all variations. When it is necessaryto refer to a particular model, a specific number is used. Referto NOMENCLATURE in this section for more information.

The NRAI0_ can be used with any of the ()ASI02, IMFBS01 orIMASI03 slave modules. The available capabilities and alterna-tives vary depending on which slave module is being used

The ASI02 slave is available in Network 90 and INFI 90 OPENform factors. They are functionally identical so far as the ter-mination assembly is concerned and are grouped by the () pre-fix.

A complete listing of product instructions for associated slaveand master modules is in REFERENCE DOCUMENTS .

The NRAO01 Analog Output Termination Assembly is comple-mentary to the NRAI0_. Refer to the documents listed in

ELSAG BAI LEY CANADA REFERENCE DOCUMENTS for com-plete information.

()ASI02

The ()ASI02 has 15 input channels to digitize voltage signalsfor use within the INFI 90 OPEN system. The NRAI0_ providesa corresponding 15 channels of field terminations. Each chan-nel of the NRAI0_ has socket pins for optional signal condition-ers and isolators.

When a channel of the NRAI0_ is being used in the straight

through mode (no isolator or conditioner), passive signal prep-aration for the analog input slave is performed. DIP switchesare used to select the signal preparation.

A broad range of conditioners and isolators are available forinstalled use in one or more channels in place of the jumper

boards supplied as standard. All conditioners and isolatorshave a common DIP switch setting. Refer to Figure 2-4 andFigures A-6, A-7, A-8, A-9, and A-10.

IMFBS01

The IMFBS01 slave has the functionality of the ()ASI02 slave, but includes Elsag Bailey field bus (smart transmitter) sup-port.

When the smart transmitters are used in the analogpoint-to-point mode there is no functional change versus the()ASI02.

NOTE: Signal isolators do not pass the field bus FSK protocol and

therefore should not be installed when Elsag Bailey field bus com-

munication is required. Refer to Figure A-12.

IMASI03

The IMASI03 enhanced slave module has 16 isolated inputs,each individually able to digitize a broad range of signal types.

The use of the optional isolators is not generally required.

The NRAI0_ performs passive signal conditioning for theenhanced analog input slave module. DIP switches are used toselect the required conditions. Low level, thermocouple andRTD inputs are routed straight through to the slave. Refer toFigures A-13 and A-14.

The NRAI02 includes cold junction compensation and must beused when thermocouple inputs to the IMASI03 are required.

INTENDED USER

This manual is intended for use by:

• Prospective customers to answer their questions about thehardware design flexibility of the INFI 90 OPEN analoginputs.

• Instrument engineers or technicians for installation, optionand programming details.

• Maintenance personnel for ongoing use of the assemblies.

EQUIPMENT DESCRIPTION

The NRAI0_ consists of screw clamp terminations for 16 input channels, mounted onto a printed circuit board and installedin an extruded plastic channel, 109 mm (4 1/2 inches) wideand 610 mm (24 inches) long. The channel has mounting feet that can attach to standard DIN rails (U or C).

INTRODUCTION

I-E96-443-1D 2 - 1

SECTION 2 - DESCRIPTION AND OPERATION

INTRODUCTION

This section provides sufficient information to allow users tounderstand the use of the assembly, document instrumenta-tion wiring connections, determine and document DIP switchconfigurations, and perform basic problem solving.

There is a considerable variety of hardware combinations pos-sible. Detailed descriptions and diagrams are used to illustrateas many combinations as possible.

FUNCTIONAL OPERATION

The NRAI0_ consists of a circuit repeated 16 times. The first 15

circuits have socket pins for the optional isolators and condi-tioners. Removable jumper boards, P/N WTL 990756, are pro-

vided with the base unit. Optional jumper boards, P/N WTL990757, are available to provide input protection againstsurges as defined by IEEE C37.90a - 1974 Surge WithstandCapability (SWC) Tests. The sixteenth circuit, which is onlyused with the IMASI03 slave module, has no socket pins.

Refer to Figures 2-5, 2-6 and 3-5 for cable connection details.

Refer to Figure 3-4 for power, common, and shield drain con-nection details.

24 Vdc power is distributed along two paths. The presence opower on each path is indicated by an LED being on g r een On the first path DS1 indicates that power is available for two

wire devices, the power leaving the termination assembly beingcurrent limited to about 170 mA per channel by 150 Ω resis-tors. The second power path is routed through fuse F1 tosocket pin 3 of the 15 conditioner and isolator mounting posi-tions, with DS2 indicating the fuse status.

The total power requirements are determined by summingindividual power requirements for each input channel per

Table 1-6.

DIP SWITCH FUNCTIONALITY

I-E96-443-1D 2 - 3

NOTES:

1. The NN refers to circuit numbers 1 to 16.

2. The dual +'ve and -'ve terminals are supplied to allow indepen-

dent marshalling. Refer to Figures A-1 through A-14 for examples.

3. The C terminal becomes the third or compensating lead of an

RTD or thermocouple cold junction compensation.

4. The SH terminal is for cable shields.

5. The terminal is used with the optional surge withstand

jumper board.

DIP SWITCH FUNCTIONALITY

S1 C1 sets the input for 4-wire transmitter operation and S1C2 is for 2-wire transmitter operation.

S17 1C1 allows voltage inputs. S17 1C2 connects a precisionresistor for conversion from 4 to 20 mA dc to 1 to 5 Vdc. S17

2C1 is for differential inputs. S17 2C2 provides a system com-mon reference.

When voltage inputs are routed to the ()ASI02 OR IMFBS01slave modules, consideration of the effect of an open circuit isnecessary. The high impedance of the input circuit will holdthe residual voltage indefinitely and the fault monitoringinherent in the system will not be triggered.

Figure 2-2. Typical Circui t Schema tic


23/68


DIP SWITCH SETTINGS

2 - 4 I-E96-443-1D

®

If the voltage input has an elevated zero, such as a 1-5 Vdc sig-nal, a bleeding resistor installed between the extra +ve and -veterminals will drain the voltage to 0 Vdc and a Bad Quality alarm will be triggered. A 4.7 MΩ, 1/4 W resistor is recom-mended for this application. Refer to Figures A-4 and A-5.

If the voltage input has 0 Vdc as a valid part of its signal rangeor if it is desirable to f a i l h i g h , special consideration isrequired. Please consult your Elsag Bailey system engineer, or refer to Section 8 - SUPPORT SERVICES .

The IMASI03 slave and the optional signal isolators have built-in open circuit detection so no special consideration isrequired for them.

If conditioners and isolators are used, the switch settings must be set for 4-wire, voltage, and system common reference (S1C1, S17 1C1 and S17 2C2).

INTRODUCTION

I-E96-443-1D 3 - 1

SECTION 3 - INSTALLATION

INTRODUCTION

This section explains the standard Elsag Bailey installationpractices as well as providing the basic information for thoseinstallations where special mounting is required.

SPECIAL HANDLING

Preassembled termination cabinets should be handled in

accordance with the instructions found in the S i t e Pl a n n i n gPr e p a r a t i o n a n d E qu i pm en t I n s t a l l a t i o n I n s t r u c t i o n .

Loose termination assemblies are shipped in foam paddedcardboard cartons. No special handling is required.

UNPACKING AND INSPECTION

The termination assemblies should be inspected for damageand/or broken components. Although the assemblies are indi-

vidually packaged in foam padded boxes, some bending ofcomponents may occur during shipment. Most of these typesof problems can be corrected by the user. Physical breakageshould be reported to the shipping company.

The Elsag Bailey part drawing is listed in ELSAG BAIL EY CANADA REFERENCE DOCUMENTS in Section 1, and should be

obtained if detailed inspection of components is necessary.

LOCATION CONSIDERATIONS

As with all electrical connections, the termination assembliesshould be mounted in environments that are relatively freefrom conductive dusts and corrosive gases. Refer to I SA Env ir o nme n t a l S t a n d a r d S 7 1 .0 4 -1 9 8 5 . The severity level should

be no worse than a good G2.

The assemblies have no exposed hazardous conductors and nospecial enclosures are needed.

SAFETY CONSIDERATIONS

No special safety considerations are necessary.

Typical Elsag Bailey Termination Cabinet Arrangement

The termination assemblies are oriented vertically on the DIN

mounting rails. The assemblies are inverted when field wiringis to be on the right hand side.

The vertical orientation allows field instrumentation wire or cable entering via the top or bottom of a cabinet, to be directly routed to the appropriate terminal block.

The most accessible areas, at the front of each side, and at thecentre of the facing surface, are available for field I/O wiring.Fifteen cm (six inches) of support space is available next to thedoor on each side. If desired, plastic wire trays can be installed

with five cm (two inches) allowed between the plastic tray andthe field terminals for wire tag visibility.

The standard Elsag Bailey cabinet has 10 divisions from top to bottom called rows and 4 location designations A to D, startingat the front left, called zones. Zones C and D are eliminated

when front access (wall mounting) cabinet options are used.Refer to Figure 3-2. Cabinet Interior and Figure 3-3. Cabinet Cross Section, for a diagrammatic representation.

The vertically oriented rail mounting system, combined withthe variable lengths of the assemblies, has led to a modifica-tion of the standard equipment location numbering system.Positions are used rather than rows and each zone has beensubdivided into (for example) A and A1. An example of the

complete location numbering system is below.

CUSTOM OR SPECIAL

The assemblies can be mounted on rails in almost any enclo-sure and orientation. When sufficient mounting width is avail-able, horizontal orientation may be used.

Figure 3-2 is an approximate scale representation of a stan-dard Elsag Bailey cabinet showing relative sizes of assembliesand the position numbering that would be used. Zone A shows3 type NRAI0_ input assemblies, zone B1 shows 3 typeNRAO01 output assemblies.

WIRING CONNECTIONS AND CABLING

Each terminal block is clearly marked with black lettering on a white clip-on tag. Several connections have compound termi-nal blocks connected by printed circuit board traces. Thesecompound blocks allow the jumping of wires while maintain-

I-E96-443-1D 3 - 5

ing a single wire in any one clamp. All terminal block functionsare uniquely marked. The cage clamp technology provides afast and secure means of wiring connection such that crimpedlugs or ferrules are not necessary.

In addition to the pre-terminated cable to the slave, three wir-

ing connections are required on the system side of the termi-nation assembly. When the optional jumper boards, P/N WTL990757 are used, a fourth connection is required.

A nominal +24 Vdc and dc common signal zero reference arerequired. Refer to Table 1-6. Connection, Configuration, PowerRequirements and Option Data for voltage tolerance, currentrequirements and necessary dc common grounding character-istics.

Field instrument cable shielding is drained by connecting thesystem side SH terminals to an appropriate ground with suffi-ciently low impedance to drain the EMF noise expected fromthe plant environment.

The fourth connection is between the terminal and chassis

ground to provide a low impedance path to ground for theunwanted incoming surges induced onto the input signal con-ductors.

OTHER EQUIPMENT INTERFACE

I-E96-443-1D 3 - 7

OTHER EQUIPMENT INTERFACE

The supplied jumper boards can be replaced with either theoptional conditioners and isolators or custom designed daugh-ter boards allowing considerable interface flexibility. Refer toFigure A-11.

The NRAI0_ can be interfaced to NDCS03, IISAC01 andNDIS0_ via the NRCS01 Termination Assembly. Refer to Figure3-5. When the IMASI03 is employed, keep in mind that theNDCS03 and IISAC01 can only accommodate 1-5 volt signalsfor direct bar graph display in the bypass mode.

PRE-OPERATING ADJUSTMENTS

Every used input should be reviewed and DIP switches setand/or conditioners or isolators installed as required.

The converters and isolators are pre-calibrated by the manu-facturer. However, for maximum accuracy, the calibrationshould be checked as outlined in Section 4 during initiainstallation and periodically as outlined in Section 6.

SECTION 4 - CALIBRATION

INITIAL CALIBRATION

The base NRAI0_ Termination Assembly requires no calibra-tion. Proper setting of the DIP switches and proper configura-tion of the associated slave and processor modules isnecessary.

The optional conditioners and isolators are calibrated by themanufacturer.

Should the calibration of the conditioners drift with time, theycan be adjusted using the potentiometers located beneath thetop label.

It is recommended that a bench or test set up be used whendoing the re-calibration of the conditioners and isolators.

Peel back the top label, and refer to Figure 4-1.

CHECKOUT

All termination assemblies are factory checked for short cir-cuits, open circuits, and functional components (DIP switches,etc.).

Termination assemblies installed in cabinet assemblies or racks by Elsag Bailey are 100% checked in conjunction withtheir respective slave modules. Refer to the Hardware/Com-munications Checkout Document listed in ELSAG BAILEY CANADA REFERENCE DOCUMENT S in Section 1.

IN-SERVICE CALIBRATION

In-service calibration is not recommended.

Table 4-1. Condit ioner and Isolator Cal ibration Procedu re

1 Determine the desired input type and span and obtain test equipment able to sim-

ulate 0 and 100% input.

1.1 Ensure that the model being used is appropriate for the desired input span.

2 Connect power supply, signal source and voltmeter as outlined in Figure 4-2.

3 Set the signal source at zero (0%) input; adjust the zero potentiometer until 1 volt(or 0 volts, depending on output range) is seen at the output.

4 Set the signal source to full scale (100%) input; adjust the span potentiometer until

5 volts (or 10 volts, depending on output range) is seen at the output.

5 Repeat steps 3 and 4 as required.

6 Set the signal source to 3 volts; check that the output is 12 mA (or 3 volts depend-

ing on output range). The isolator should be replaced if half scale accuracy is not

acceptable.

7 The conditioner or isolator is now ready for installation on to the termination

assembly.

SECTION 5 - TROUBLESHOOTING

INTRODUCTION

As an essentially passive device, it is unlikely that the termina-tion assembly will be the source of an equipment failure. Verifythat the procedures outlined in Section 6 have been per-formed.

Any personnel performing troubleshooting should be familiar with both the hardware and software aspects of the systemand related field devices.

ERROR MESSAGES AND CORRECTIVE ACTION

Error messages pertaining to system inputs and outputs are

reported within the status bytes and error codes of the appli-cable controller or processor module. Refer to the REFERENCE DOCUMENT S in Section 1 of this manual to determinethe appropriate controller or processor module instruction

book.

When operator interface stations are provided, the I90 Statusdisplays, which translate the module status bytes into textmessages, allow operators or maintenance personnel to iden-tify specific point malfunctions.

PROBLEM DETERMINATION AND VERIFICATION PROCEDURES

In an industrial setting there may be a variety of causes forequipment malfunction. The age of a device, the quality of theenvironment (including extreme heat, temperature swingscorrosive gases, and conductive dusts) and of course, humanerror and accidents.

As previously mentioned, the Elsag Bailey system can assist inthe location of a problem at a particular slave or input. Keep inmind that the termination assembly is the division betweenfield equipment and the DCS software (configuration), so bothmust be considered when pinpointing a problem.

TROUBLESHOOTING GUIDE

The following guide is intended to assist in troubleshooting bydetailing the areas within the Elsag Bailey system that should

be considered.

SECTION 7 - REPAIR/REPLACEMENT PROCEDURES

INTRODUCTION

The base termination assembly has no active components andhas been carefully designed to tolerate as many field wiringinconsistencies as possible. Without the optional conditionersand isolators, incorrect field wiring or DIP switch settings canresult in damage to a connected slave module.

Inadvertent connection of a supply voltage greater than 48 Vdc will result in the destruction of one or both power supply sta-tus LED's DS1 and DS2. Damage to isolators and conditionersmay also occur if the incorrect voltage remains connected foran extended period.

The optional conditioners and isolators provide protection tothe input of up to 240 Vac for limited time durations. Refer tothe Isolator Procedures in Section 4 - CALIBRATION .

PROCEDURES

Refer to Section 5 - TROUBLESHOOTING before replacingShould replacement of the assembly be necessary, the mostimportant connections to check are the +24 and COM. Theseconnections are often in a daisy chain arrangement and dis-connecting them could result in the loss of power to otherfunctioning termination assemblies.

The daisy chaining done by Elsag Bailey is normally in a loopso that no power loss will occur if only a single terminationassembly is removed. Refer to the p ow er w i r i n g d r a w i n g ssupplied with your system to verify the wiring scheme used.

To replace the termination assembly, follow Table 7-1.

Table 7-1. Termin ation Assemb ly Replacement

1. Obtain a suitable replacement termination assembly.

1.1 Ensure the availability of an appropriate replacement fuse.

2. Remove any cables connected to P1, P3, P4, P5 and P6.

3. Tag and disconnect all connections to the field side of the termination assembly.

4. Disconnect and insulate the +24, COM and SH (shield) wiring.

5. Remove the termination assembly using a medium flat blade screwdriver at

each of the four mounting feet. Refer to Figure 7-1. Mounting Foot Release.

6. Set all DIP switches on the replacement assembly to match the removed unit.

.

6.1 Move any optional conditioners and isolators to the replacement assem-

bly, ensuring any thermocouple converters have a cold junction compen-

sating thermistor mounted between the extra +’ve and C terminals.

6.2 Install F1 if required.

7. Install the replacement assembly by ensuring that each of the four feet engageon the system side, then pivot the field side in until all feet have latched into

place.

8. Reconnect the system side +24, COM and SH wiring.

9. Reconnect all field side wiring.

10. Reconnect all system side cabling.

11. Verify proper operation of inputs. Refer to Figure 5-1. Troubleshooting Guide.
