Operation overview

2. Operation overview

2.1 Theory of operation

The HC600 transmitter module illuminates a direct linear path endingat the HC600 receiver module. As flammable hydrocarbon gasesintersect the light beam between the two modules, the gas absorbscertain IR wavelengths, while other IR wavelengths are not. Theamount of IR absorption is determined by the concentration of thehydrocarbon gas. A pair of optical detectors and associatedelectronics located in the receiver module measure the absorption.The change in intensity of the absorbed light (active signal) ismeasured relative to the intensity of light at a non-absorbedwavelength (reference signal). The microprocessor computes the gas

concentration and converts the value into a 4 to 20 milliamperecurrent output signal, which is then communicated to external controland annunciation systems. No filter wheel motors or other movingparts are utilized in either module.

2.2 Lamp redundancy

The HC600 transmitter provides a unique operational feature. A xenonlamp illuminates the linear detection path from the transmitter to thereceiver. In the event that the primary lamp fails, the back-up lamp is

brought into service. The receiver recognizes this condition by thechange in flash pulse coding and responds by initiating a “failed lamp”warning signal to indicate that the back-up lamp is in use. Totalsystem operation is maintained, with no loss of sensitivity or detectionperformance. In this mode of operation, the following occur:

1. The indicator LED turns amber.

2. The 4-20 mA signal drops from a normal 4 mA to 2.4 mA. Theanalog output value is overridden if the gas level exceeds 0.5 LEL-meters. All gas alarm signals will occur as when operating with theprimary lamp.

3. HART and MODBUS communication warn of a “failed lamp”condition.

Service should be arranged as soon as possible. A new transmittermodule should be installed.

2.3 Detectable gases

The HC600 is capable of detecting most hydrocarbon gases andvapors including methane, ethane, propane, butane, and propylene.

Gas type and other operational parameters are selected via digitalcommunications. The factory-calibrated setting is methane.

2.4 Outputs

An isolated 4 to 20 mA current loop corresponding to 0 to 5 LEL-meters is provided for connection to analog input devices such as gascontrollers, logic controllers, or distributed control systems (DCS).(Relay outputs will be available in a future release.)

2.5 Communication

The standard HC600 system provides an analog 4-20 mA signaloutput, with HART and RS-485 MODBUS serial communication fromthe receiver module.

2.6 Recording capability

Non-volatile memory is provided to save the 10 most recentcalibrations, alarm/fault events, and minimum/maximum operatingtemperature history. A real time clock is provided to record operatingservice time and to time stamp events. This information is accessibleusing HART and MODBUS communication.

3.2.3 Alignment

The HC600 modules must be properly aligned before normaloperation is attained. There are two alignment procedures:

1. Basic alignment requires the HC600 alignment kit. A handheld

HART communicator is recommended, but not required.

2. Full alignment requires the HC600 alignment kit and a handheldHART communicator.

3.2.4 Calibrate

After alignment is completed, zero calibration is required. Futurecalibration of the HC600 is normally not required; however, the userhas the option to verify proper calibration or to perform calibration

procedures if necessary. Refer to the "Calibration" section in thishandbook for details

3.3 4 to 20 mA current loop output

HC600 provides an isolated, linear current loop output that isproportional to the detected gas level. Fault and calibration status arealso indicated by this output.

The factory default for full-scale 5 LEL-meters output is 20 mA.MODBUS interfaces also have the ability to calibrate the 4 mA and 20

mA levels.

Installation


Page 15

6. Installation

6.1 Identi fication of vapour(s)to be detected

It is necessary to identify the flammable vapor(s) of interest at the jobsite in order to determine the proper calibration gas setting for the AutroPath HC600. In addition, the physical and fire hazard propertiesof the vapor, such as vapor density and flashpoint should be identifiedand used to assist in selecting the optimum detector mountinglocations within the area. Qualified personnel only must install thedetector, following local electrical equipment installation practices.

6.2 System location considerations

The HC600 system is designed for installation in hazardous industrialareas. Each module is normally installed using a solid vertical steelpost or flat surface-mounting adapter to support the weight of themodule. The modules must be strategically located so that thehydrocarbon vapor(s) to be detected will intersect the light beamgenerated by the transmitter module. Dispersion characteristics andbehavior of the vapor cloud resulting from a gas leak can be difficult toestimate due to the significant number of variables that exist atdifferent applications. Identification of expected gas leakagesource(s), leak scenario identification, and onsite leak simulation are

the steps generally recommended to provide the most accuratemeans of identifying optimum system installation locations.

In all cases, the beam path and surrounding area should be kept freeof obstructions that could block the infrared beam or hinder the freemovement of air within the area. A clear beam path of 20 cm diameteror greater is recommended. The system is immune to the effects ofexposure to both direct and reflected sunlight.

Avoid installation in areas with obstructions such as steam vents andplumes, smoke stacks and chimneys, walkways and personnel areas,splash and sprayed water, parking, loading, cranes, vehicle-relatedareas such as bus stops, road junctions, and vegetation such as

trees, shrubs, etc.

Autronica’s Field Service Engineering group routinely provides jobsiteapplication surveys and analysis for customers, and their services arehighly recommended if guidance on optimum installation locations isrequired. Additional guidance on the positioning of gas detectors foroptimum coverage is contained in BS6959 and other national codes.Consult these codes of practice when determining where detectorsare to be located.


18/50

Installation


Page 16

Consideration of the following system location guidelines is alsorecommended:

6.2.1 LED visibil ity

Select a mounting orientation where the HC600 status indication LEDis visible to personnel within the area.

6.2.2 Module separation distance

The transmitter and receiver modules must be installed directly facingeach other across the area to be protected. Physical obstructions inthe direct line of sight between the modules are not permitted. Theoverall line of sight distance between the modules must not exceed a

maximum separation distance of 60 meters (198 feet). The minimummodule separation distance is 20 meters (66 feet), unless specialmodifications are provided.

6.2.3 System mounting elevation

In all cases, the modules should be installed at the same elevationabove grade to ensure that alignment capability and foul weatherperformance are not compromised. For detection of lighter than airvapors such as methane, installation of modules at approximately 2

meters above grade minimizes typical beam block conditions due tohuman activities, while enabling satisfactory detection capability. Fordetection of heavier than air vapors, installation of detectors below theexpected leakage source is generally recommended unless nuisancebeam blocks will occur at an unacceptable rate. In this case,identification and analysis of application specific conditions should becompleted to determine the optimum installation elevation.

6.2.4 Sources of heavy contamination

Avoid locations where high levels of contaminants will persistently beblown onto the detector windows. Potential sources of heavycontamination include generator/turbine exhausts, flare stacks, drillingequipment, process vents/chimneys, etc. If sources of heavycontamination cannot be avoided, consider fitting extra shieldingand/or providing good access for routine cleaning.


19/50

Installation


Page 17

6.2.5 Snow and ice in ambient below –20°C

The heated optics on both modules will melt snow or ice on thewindows in ambient temperatures down to approximately –20°C.Below this temperature, snow or ice blown onto the window will not bemelted until the ambient temperature rises. If long-term outdoor

operation in very cold climates is intended, extra shielding/covers arerecommended to prevent accumulation of snow and ice on thewindows.

6.2.6 Deluge and flooding

The modules are rated IP66 and will not be damaged by occasionaldeluge or flooding. However, during such an event, the unit willcompletely lose its IR signal and will enter the “Beam-Block/Fault”state. In addition, when the deluge/flooding subsides, there is the

possibility that contaminants will be left on the windows. Install themodules away from areas particularly prone to deluge or flooding.

6.2.7 Areas prone to subsidence and settling

Avoid installation of the modules in areas where problems withsubsidence, settling or thawing of permafrost can occur or causesignificant movement. If such locations cannot be avoided, thefoundations of the mounting structure should be engineered tominimize any angular movements.

6.2.8 Areas prone to earthquakes

In the event of an earthquake, there is a chance that the modules willbecome misaligned with respect to each other. As long as themodules do not suffer from direct mechanical impact damage duringan earthquake, they should remain undamaged by such events. Afteran earthquake, it is recommended that the system alignment bechecked. Anti-vibration mounts are unlikely to be of any benefit andare not recommended.

6.2.9 Misalignment by accidental impact

Locations where there is a significant likelihood of equipment,personnel or moving objects accidentally knocking the modules out ofalignment should be avoided where possible. If such locations cannotbe avoided, measures including improved mechanical protection andwarning notices should be considered.


20/50

Installation

6.3 Module mounting recommendations

After optimum system module mounting locations are identified, thepreferred module-mounting configuration must be selected. Eachmodule must be affixed to a solid, non-vibrating structure capable ofsupporting a minimum of 100 lbs (46 kg), located within the system’s

maximum rated separation distance. Module mounting optionsinclude:

• A vertical post with a nominal outside diameter of 4.5” (11.43 cm). Acceptable outside diameter range is 4.0 to 5.0 inches. Ensurethat each post is capable of supporting a minimum of 50 lbs (23kg). See Figure 3.

• For flat surface mounting, the HC600 flat surface mount adapter isavailable. Ensure that the flat surface is capable of supporting aminimum of 100 lbs (46 kg). See Figure 4. For mounting holepattern, refer to Figure 5.

In all cases, the maximum movement of the supporting structureunder all anticipated operating conditions must be no more than ±0.5degrees. When using a vertical post, the post should be absolutelystable and without vibration. Generally, when the post is set into theground, the portion below grade should be set in concrete at least 1meter deep.

When using the flat surface-mounting adapter, ensure that the twovertical mounting surface planes are aligned sufficiently to enableproper module alignment. It is possible that some existing flatsurfaces may not allow proper system alignment using the HC600mounting and alignment hardware.

System modules are shipped disassembled from the mounting

hardware. Before proceeding with module installation, ensure that allrequired module installation components are present, including:

• 2 HC600 modules,

• 2 module mounting brackets,

• 2 pan-tilt plates,

• 4 U-bolts complete with

• 8 washers and nuts, and

• 2 plate support collars.

For flat surface mounting, two HC600 flat surface mount adapters(ordered separately) must be installed prior to starting the moduleinstallation procedure.

6.4 Module installation procedure(Must be completed for both transmitter and receiver modules)

1. Install the plate support collar onto the vertical post at the desiredheight. Ensure that the plate support collars for both modules areinstalled at the same distance above grade/floor elevation toensure ease of optical alignment later. Tighten the plate supportcollar nuts and bolts to adequately support the entire assembly.

2. Install the mounting plate on the vertical post using (2) u-bolts, (4)washers, and (4) nuts. Tighten the nuts snugly by hand only atthis time so that the plate is adequately supported but may berotated if required.

3. Install the HC600 module onto the mounting plate. Tighten snuglyto support the weight of the device.

4. Double check to ensure that the module is adequately supportedand is ready for electrical wiring.

IMPORTANTDo not allow any water or other contaminants to enter the HC600electrical termination enclosure if a delay is expected.

6.5 24V DC power supply requirements

Calculate the total gas detection system power consumption rate inwatts from cold start-up. Select a power supply with adequatecapability for the calculated load. Ensure that the selected powersupply provides regulated and filtered 24V DC power for the entire

system. If a back-up power system is required, a float-type batterycharging system is recommended. If an existing source of 24V DCpower is being utilized, verify that system requirements are met.

NOTEIf disconnection of power is required, separate disconnect capabilitymust be provided.

6.6 Wiring-cable requirements

Always use proper cabling type and diameter for input power as wellas output signal wiring. 14 to 18 AWG (0.75 – 2.0 mm²) shieldedstranded copper wire is recommended.

Always install a properly sized master-power fuse or breaker on thesystem power circuit.

NOTEThe use of shielded cable in conduit or shielded armored cable isrecommended for optimum RFI/EMI protection. In applications wherethe wiring is installed in conduit, dedicated conduit is recommended. Avoid low frequency, high voltage, and non-signaling conductors toprevent nuisance EMI problems.

CAUTIONThe use of proper conduit installation techniques, breathers, glands,and seals is required to prevent water ingress and/or maintain theexplosion-proof rating.

Page 21

6.7 Power wir ing size and maximum length

1. The HC600 detector must receive 18V DC minimum to operateproperly. 24V DC minimum is recommended.

2. Always determine voltage drops that will occur to ensure that 24V

DC is delivered to the HC600.

3. Normally, Autronica recommends that nothing smaller than 18 AWG (0.75 mm2) be used as HC600 power cabling.

Wire size requirements are dependent upon power supply voltage andwire length.

The maximum allowable voltage drop for the power-wiring loopdetermines the maximum distance between the HC600 detector andits power supply. If the voltage drop is exceeded, the device will notoperate. To determine the maximum power loop voltage drop,subtract the minimum operating voltage for the device (18V DC) fromthe minimum output voltage of the power supply.

To determine the actual maximum wire length:

5. Divide the maximum allowable voltage drop by the maximumcurrent draw of the HC600 (0.64 A),

6. Divide by the resistance of the wire (resistance value available inwire manufacturer’s specification data sheet),

7. Divide by 2.

For example: Consider an installation using 18 AWG (0,75 mm²)wiring with a power supply providing 24V DC.

Power supply voltage = 24V DC,HC600 minimum operating voltage = 18V DC

24 – 18 = 6V DC

Maximum voltage drop = 6Maximum current = 0.64 AWire resistance in ohms/foot = 0.006523 (0,02138 ohms/m)

6 ÷ 0.64 ÷ 0.006523 ÷ 2 = 718 feet

(6 ÷ 0,64 ÷ 0,02138 ÷ 2 = 219 m)

6.8 Wiring procedure

For systems using conduit, modules must be wired using a shortpiece of suitable flexible conduit to allow optical alignment of themodules. Ensure that all cables are terminated properly. AutroPathHC600 screw terminal torque range is 3.5–4.4 in.-lbs. (0.4–0.5 N·m).

Cable shield, if used, should be properly terminated. If not terminated,clip the shield wire off short and insulate it within the detector housing

to prevent the shield wire from accidentally contacting the detectorhousing or any other wire.

7. Start-up

When the HC600 is installed and wired as described in the“Installation” section, it is ready for commissioning. If the application

requires that specific changes be made to the factory settings, HARTcommunication will be required.

NOTEEnsure that alarm devices are bypassed during commissioning.

7.1 Alignment

7.1.1 Overview

The HC600 modules must be properly aligned before normaloperation will be attained. There are two alignment procedure options:

1. Basic alignment procedure. This option requires either thetelescope alignment kit p/n 116-009104-001. It does not require ahandheld HART field communicator.

2. Fine alignment procedure. This option requires a handheld

HART field communicator with the HC600 device descriptor (DD)software menu such as the Emerson model 375 fieldcommunicator. The full alignment procedure is recommendedwhenever maximum optical signal strength is required, includingall outdoor installations and any installation where the monitoredpath length is longer than 40 meters.

NOTEBasic alignment must be successfully completed before attemptingfine alignment.

7.1.2 Basic alignment procedure

Equipment required:

1. Properly installed and powered HC600 system (transmitter andreceiver). Easy access to both modules is highly recommended.

2. Telescope alignment tool p/n 116-009104-001. The telescopealignment tool is recommended for use in commissioning allHC600 systems, and the following instructions cover the use ofthe telescope alignment tool only.

3. Calibration magnet.


28/50

Start-up

4. For installations with module separation distances between 5 and30 m, a range reduction aperture kit is required. Refer to the“Ordering information” section of this manual for part numbers.

Remove operating power from the HC600 transmitter, and then

complete the following steps:

1. Ensure that both system modules are installed and wiredproperly on their respective mounting plate/post assemblies at aseparation distance within the specified range. Bypass allexternal gas alarm devices that are connected to the receiveroutputs.

2. Ensure that the system modules are installed with their windowsat approximately the same height above grade. Each moduleshould be roughly aligned to directly face the window surface ofthe other module.

3. Ensure that all U-bolt nuts are completely tightened to properlysupport the modules. See Figure 15.

4. Ensure that the vertical alignment locking nuts are sufficientlytightened to properly support the vertical angle of the modulewithout deflection, yet allow the module to be vertically adjustedby hand without binding. It is recommended to tighten the lowerbracket nut slightly more than the upper bracket nut.

17. Confirm proper operation by blocking the light beam with a solidobject such as cardboard until a beam block fault is generated.

18. Confirm proper operation by installing the optical test film (p/n007902-001) into the light beam and inspecting for correspondingsignal output level of 1.2-1.8 LEL-meters on the HARTFieldcommunicator Process Menu screen. The alarm conditionshould clear when the film is removed from the beam.

7.1.3 Fine alignment procedure

The fine alignment procedure should be completed when maximumoptical signal strength is required at the receiver module, such asmost outdoor applications and all installation areas with high levels ofoptical contamination or fog.

It is necessary to complete the basic alignment procedure beforestarting the fine alignment procedure. A handheld HARTcommunication device such as the intrinsically safe Emerson model

375 HART communicator is required to complete finel alignment.

The HC600 transmitter is generally not adjusted when performing thefine alignment procedure, provided it has been properly aligned duringthe basic alignment procedure.

7.1.3.1 HART field communicator recommendations

NB!: Be aware thet the HART communicator refers to the HC600as OPECL.

• Ensure that the HART communicator to be used is certified for usein classified areas.

• The HART communication device used for full alignment mustinclude the OPECL device descriptor (DD) software menu. Theuse of HART communication devices without the proper DDs mayestablish generic mode HART communication, but will not enableFull Alignment to be completed. Refer to the HART appendix foradditional information.

• A minimum level of understanding with regard to the operation andnavigation of the HART communicator is required to complete theFull Alignment procedure. Please refer to the appropriate HARTcommunicator instruction manual for basic operating instructions ifrequired. Additional information on the use of the HARTcommunicator is provided within the HART Appendix in thisdocument.

• For proper HART communication to occur, it is required that a 250-500 ohm resistive load be present in the HC600 analogue 4-20 mAsignal loop output.

7.1.3.2 Procedure

After completion of the basic alignment procedure, perform the finealignment procedure as follows:

1. Connect the handheld HART communicator to the receivermodule’s onboard HART communication port.

2. Turn on the HART communicator and check for OPECL devicerecognition. When HART communication is established, theOPGD Rx Root menu will be displayed on the communicatordisplay screen.

3. From the Root menu, select the Status menu (selection #2).

4. From the Status menu, select the Sensor information menu(selection #3).

5. The Sensor information menu will display the following screen.

1) Active XXX

2) Reference XXX3) Ratio XXX

4) Gas Gain X

5) Absorption XXX

Gas Gain number

(adjust to minimum level)

6. Observe the gas gain level indicated on the Sensor informationmenu screen. The maximum acceptable gas gain level is 3. Theoptimum gas gain level is 2.

7. If a gas gain level of 3 or less is not displayed, adjustment of theHC600 receiver alignment is required until the gas gain levelindicated is 3 or less.

NOTEDo not attempt to tighten any threaded adjuster bolt if the opposingadjuster bolt is tightened hard against the mounting plate hardware. It


Page 29


32/50

Page 30

is necessary to slightly loosen the opposing adjuster bolt in all casesbefore attempting to tighten an adjuster.

8. Adjust the horizontal alignment angle first in small increments. After an adjustment is made, wait for at least 10 seconds for thegas gain display level to stabilize. Adjust left and/or right, if

necessary, until the correct level is achieved.

NOTEDuring alignment adjustment, the HART field communicator mayoccasionally display a message stating “Non-zero status codes found.Ignore the next 50 occurrences?” When this occurs, enter “Yes”, andcontinue the fine alignment procedure.

9. If unable to achieve a gas gain level of 3 or less using horizontaladjustment, adjust the vertical alignment angle in smallincrements. After an adjustment is made, wait at least 10 secondsfor the gas gain level to stabilize. Adjust the vertical alignmentangle until the correct level is achieved.

10. When the gas gain level is 3 or less, tighten all bolts and nuts.

11. Perform a zero calibration on the HC600 receiver module.

12. Upon completion, the HC600 receiver should produce a 4 mAoutput signal and a green LED indication. If not, repeat steps 8and 9.

13. Bypass all system alarms and confirm proper operation byinstalling the optical test film p/n 116-007902-001 into the lightbeam and checking for a corresponding signal output level of 1.2-1.8 LEL-meters on the HART Fieldcommunicator Process Menu

screen. The alarm condition should clear when the film isremoved from the beam.

14. Confirm proper operation by blocking the light beam with a solidobject such as cardboard until a beam block fault is generated.

15. System is fully aligned when steps 12, 13, and 14 are successfullycompleted.

16. Double check the gas gain value to ensure that there has notbeen module movement.

7.2 Calibration

7.2.1 Calibration overview

Although routine calibration of the AutroPath HC600 is normally notrequired, the device supports non-intrusive field zero calibrationcapability. Span calibration is not required.

7.2.1.1 Zero calibration

Zero calibration is a one-step process consisting of clean air (zero)condition adjustment only, which is performed automatically by thedevice. This procedure adjusts the "clean air" signal output only, and

is normally used if the 4-milliampere signal level has drifted. Thecause of drift is typically due to the presence of background gasduring calibration. Ensure that the optical path is clear ofhydrocarbons prior to calibration initiation to ensure an accurate zero(clean air) condition.

IMPORTANT CALIBRATION NOTES

NOTEEnsure that the detector has been operating for at least two hoursbefore calibrating.

NOTE

Always ensure that the HC600 optics are totally free of allhydrocarbons before initiating calibration.

7.2.2 Calibration ini tiation

Calibration may be initiated by any of the following means:

• The onboard magnetic calibration switch

• Digital communication via MODBUS communication (consultfactory for details)

•

Remote calibration line.

7.2.2.1 Calibration using magnetic switch

The AutroPath HC600 provides an onboard magnetic calibration/resetswitch for non-intrusive calibration capability. The magnetic switch isactivated by holding a calibration magnet at the specified lopvation onthe device bulkhead. See figure 1 for switch location. An onboard tri-color LED provides status indication during calibration.

For zero calibration, the magnetic switch must be actuated for 2seconds to initiate calibration (signaled by a solid red LED). Upon

initiation, the HC600 automatically performs the zero calibrationadjustment, and then signals with a green LED when this operation iscomplete.


34/50

Start-up


Page 32

Zero calibration procedure

1) Apply magnet for 2 seconds minimum to initiate calibration.

a) The onboard LED turns to steady red.

b) The current output decreases to 1 mA.

2) When zero calibration is complete:

a) The onboard LED changes from steady red to steady green.

b) Calibration is complete and current output returns to 4 mA.

7.2.2.2 Digital communication calibration

MODBUS communication may be utilized to initiate HC600 calibration(consult factory).

Maintenance


Page 33

8. Maintenance

8.1 Routine inspection

The AutroPath HC600 detector should be inspected periodically toensure that external obstructions such as plastic bags, mud, snow, orother materials do not block the path and thereby impair theperformance of the device.

8.2 Optics cleaning

Cleaning of the HC600 optical surfaces is normally required only if anoptical fault is indicated.

Thoroughly douse both window surfaces using a liberal amount ofisopropyl alcohol to clear away contaminant particles. Repeat thealcohol flush to remove any remaining contaminants.

8.3 Protective caps and covers

Ensure that the HART communication port cover and the wiring

compartment cover are installed and fully engaged.

9. Troubleshooting

A Fault status is indicated by a yellow LED and also by the 4 to 20 mAoutput. Refer to Table 4 for assistance in correcting malfunctions with

the AutroPath HC600 detector.

Fault condition Corrective action

Low 24 volts 24V DC operating voltage is out of range. Verifyproper wiring to the detector and correct voltageoutput from the power source. Power supplyfaults are self-clearing when the condition iscorrected. If the fault does not clear, consult thefactory.

Dirty optics Perform cleaning procedure, then recalibrate asrequired. (Refer to “Maintenance” for details.)

Calibration fault If the calibration process is allowed to time-out,the fault is set and can only be reset with a

successful calibration.Negative signaloutput

This fault is indicated when the signal outputdrops below 0.5 LEL•M. Normally detectioncapability is not compromised in this condition.The device was probably zero calibrated withbackground gas present. If the condition persists,purge with clean air and repeat the zerocalibration

Calibration lineactive at start-up

The only way to clear this fault is to correct thewiring and reapply power. Be sure that thecalibration line is not shorted and that thecalibration switch is open. If the fault does notclear, consult the factory.

EE error If power is interrupted while the unit is updatingits internal data logs, an EE Error may occur.Cycling power will correct this fault.

Other faults Consult the factory.

Appendix: HART communication


Page 37

12. Appendix: HARTcommunication

Digital communication with the AutroPath HC600 is necessary tomonitor internal status and to modify the factory settings. Thisappendix provides guidance on establishing HART communication,and describes the communication menu structure when using theHC600 with the HART candheld communicator.

12.1 Interconnecting the HART communicator with the AutroPath HC600 (OPECL)

Unscrew the protective cap from the HART communication port on theside of the AutroPath HC600 receiver. Connect the HARTcommunicator to the two terminals inside the port. Press the "on" keyto switch on the HART communicator. The Online menu is the firstmenu to appear when the communicator is properly connected to the AutroPath HC600. This menu is structured to provide importantinformation about the connected device immediately on powering upthe communicator. This menu displays up-to-date device informationincluding primary variable, analog output, lower range value, andupper range value.

NOTEThe HART protocol incorporates a concept called the "DeviceDescription Language" that enables all suppliers of HART instrumentsto define and document their products in a single consistent format.This format is readable by handheld communicators, PCs and otherprocess interface devices that support DDL. DDL enables fullinteroperability of devices, regardless of manufacturer, allowing fullfunctionality from any HART device.

In the event that your communicator does not establishcommunications with the AutroPath HC600, you may need to ensurethat the appropriate DDL’s for the AutroPath HC600 (OPECL) areincluded within yourcommunicator. To review the device descriptionsprogrammed into your HART communicator:

1. From the Main menu, press to access Offline menu.

2. From the Offline menu, press New Configurations to access thelist of device descriptions programmed into your HARTcommunicator. The Manufacturer menu displays a list of eachmanufacturer with device descriptions currently installed in yourcommunicator’s Memory Module. The standard 12 MB MemoryModule is recommended, as it allows for more devicedescriptions.

3. Select a manufacturer, and the Model menu displays, containing alist of currently installed device models provided by the selectedmanufacturer.

4. Review the different manufacturers and models to determine theinstalled HART-compatible devices in your communicator.


40/50



Page 38

If you cannot find the AutroPath HC600 (OPECL) device on yourcommunicator, the device revision you are looking for is notprogrammed into the Memory Module. In this instance, you are limitedto what is available using the generic interface built into yourHARTcommunicator.

The HART Communication Foundation (www.hartcomm.org)manages a library of manufacturer device descriptions, which aredistributed to programming sites for inclusion in master devices. Acomplete listing of the HCF DD library is available for download inmanufacturer (Detector Electronics Corporation) and device typesequence.

NOTEIf a device is found, the HART communicator displays the Onlinemenu. If no device is found, thecommunicator displays the Mainmenu. If no device is found, check the connections, verify thepresence of a minimum of 250 ohms load resistance in series in theloop, and retry by selecting ‘Online.’ To poll multiple devices in the

loop, refer to the HART communicator manual.

12.3 Connections and hardware

The HART communicator can interface with the AutroPath HC600from the onboard I.S. communication port, from the control room, orfrom any wiring termination point in the analog output signal loop. Tocommunicate, connect the HART communicator in parallel with the

AutroPath HC600 analog signal or load resistor. The connections arenon-polarized.

NOTEThe HART communicator needs a minimum of 250 ohms resistancein the loop to function properly. The HARTcommunicator does notmeasure loop current directly.

12.4 Online menu

When HART communication is established with the receiver, the firstmenu displayed is the OPGD RX (HC600) root menu:

12.5 Commonly used HART commands

The most commonly used HART commands for the model HC600(OPECL) are:

1. Setting the real time clock

2. Setting alarm thresholds & latch/nonlatch functions3. Setting the analog fault code menu4. Performing full system alignment5. Performing zero calibration6. Assigning a nonvolatile tag name to the receiver7. Defining a nonvolatile descriptor for future reference8. Interrogating the history menu for information including total

running hours, max/min exposed temperature, calibration andevent logs.

12.5.1 Setting the real-time clock

Generally, the first step recommrnded after achieving HARTcommunication with the HC600 Rx is to set the real-time clock (RTC).To accomplish this, Select the following options:
