INSTRUCTIONS line of Sight infrared Hydrocarbon Gas Detector

Model autropath Hc800

Important

Be sure to read and understand the entire instruction manual before installing or operating the gas detection system. This product is intended to provide early warning of the presence of a flammable or explosive gas mixture. Proper device installation, operation, and maintenance is required to ensure safe and effective operation.

application

The Model AutroPath HC800 is a line of sight infrared gas detection system that provides continuous monitoring of combustible hydrocarbon gas concentrations in the range of 0 to 5 LFL-meters, over a distance of 5 to 120 meters. Standard system outputs include an electrically isolated/non-isolated 4–20 mA dc current output with the ability to go below 4 mA to indicate fault conditions, and also HART and RS-485 Modbus communication.

Alarm and fault relays are available as an option.

The system consists of two stainless steel modules — a transmitter and a receiver, along with mounting and alignment bracket. The receiver provides the measurement signal outputs, and is furnished with onboard “status indication” LEDs and an internal magnetic calibration switch. The transmitter houses a high quality xenon flash lamp and “status indication” LEDs. Both modules are powered from an external 24 volt DC supply and are equipped with microprocessor controlled heated optics to increase resistance to moisture and ice. Both modules must be installed at approximately the same elevation and must be aligned to point directly at one another. No direct electrical interconnection between the two modules is required.

The AutroPath HC800 is certified explosion-proof for use in zone 2, category 3 hazardous areas, and holds third party performance certification for Methane,

Butane, and Propane gas detection. It can be used as a stand-alone detector, or as part of a larger facility protection system using other Autronica Fire and

Security equipment.

The AutroPath HC800 transmitter module uses a Xenon flash lamp to produce a collimated IR light source. This light source illuminates the path between transmitter and receiver. The transmitter uses a filter to block visible light emissions and is eye safe.

As flammable hydrocarbon gases intersect the light beam between the two modules, certain IR wavelengths are absorbed by the gas, while other IR wavelengths are not. The amount of IR absorption is determined by the concentration of the hydrocarbon gas. A pair of optical detectors and associated electronics located in the receiver module measure the absorption. The change in intensity of the absorbed light (active signal) is measured relative to the intensity of light at a non-absorbed wavelength (reference signal). The microprocessor computes the gas concentration and converts the value into a 4–20 mA current output signal, which is then communicated to external control and annunciation systems.

The gas concentration is indicated by a 4–20 mA signal, which corresponds to 0-5 LFL-meters. To better understand the concept of LFL-meters, refer to Figure

1, which shows how three gas clouds of different size and concentration would produce the same output of

1 LFL-meter by the line of sight gas detection system.

To convert a given LFL-m value to ppm-m for methane, propane, or butane gas, refer to Table 1.

1M @ 100% LFL = 1 LFL-M

DeteCtABLe GASeS

The AutroPath HC800 is capable of detecting most hydrocarbon gases and vapors including methane, propane, and butane. Gas type and other operational parameters are selected via HART or Modbus communication. The AutroPath HC800 is factory calibrated to methane, propane, and butane, and comes from the factory set for methane. For detection of gases other than the three selection settings (methane, propane, and butane), performance characteristics / transfer curves are available. Please contact the factory for details.

DeteCtIoN RANGeS

The AutroPath HC800 is offered in two detection ranges in order to meet customer needs, as listed below:

Short Range 5–60 meters

Long Range 30–120 meters

For installations with short separation distances (5-15 meters for the short range model and 30-40 meters for the long range model), the range reduction aperture kit

(supplied) is required. Refer to “Aperture Kit for Short

Range Applications” section in this manual for details.

The correct range for the AutroPath HC800 must be chosen to meet specific application needs. The detection range of the AutroPath HC800 pair is determined by the Receiver. Receiver units can be converted from long to short or short to long range in the field by replacing the front electronics module.

A single transmitter model is used for both detection range options.

10M @ 10% LFL = 1 LFL-M

2M @ 50% LFL = 1 LFL-M

A2665

StANDARD outPut

The AutroPath HC800 receiver module provides an analog

4–20 mA signal output. HART and RS-485 Modbus serial communication are available at either module. The 4–20 mA current loop corresponding to 0–5 LFL-meters is provided for connection to analog input devices such as gas controllers, logic controllers, or distributed control systems (DCS). To convert the mA reading to

LFL-meters, use the following formula:

oPtIoNAL ReLAyS

The AutroPath HC800 can be furnished with factory installed relays — two programmable alarm relay outputs and one fault relay output. All relays are sealed and provide form C (NO/NC) contacts. The high and low alarm relays are programmable, and can be set for latching / non-latching operation, and a normally energized / de-energized coil (see Table 3). The low alarm cannot be set above the high alarm threshold.

Alarm configuration can be done with the HART or

Modbus interface. The onboard multi-color LEDs indicate a LOW alarm condition via a flashing red color, and a HIGH alarm condition via a steady red color. Latched alarms can be reset using the internal magnetic switch, an external switch connected to the calibration line terminal, a HART Field Communicator, or Modbus communication. A short-duration magnetic switch activation of one second will reset latched alarms. Holding the magnetic switch closed for a three second duration will start the calibration sequence.

3. Synchronized LEDs on each device can signal a common system status condition. Without the link, the transmitter is unable to signal alarm status.

4. Transmitter variables can be configured via connection to the receiver. Configurable transmitter variables include lamp power and heater settings.

NoTe

Alarm setpoints in the receiver cannot be changed from the transmitter.

5. The communication link provides the ability to initiate Calibration from either the transmitter or receiver.

For retrofit applications where an inter-connecting wire is not available or possible, the system can operate without the link. If the link is not connected, the system will not indicate a “link fault.”

When the optional relays are ordered, the AutroPath

HC800 receiver is certified for Ex d operation.

A “link fault” feature can be enabled (using a HART handheld or Modbus device), which will indicate a fault if the link is broken. The “link fault” can only be detected and annunciated by the receiver. oPtIoNAL CommuNICAtIoN LINk

By connecting the transmitter and receiver via a threewire shielded cable, an optional “communication link” can be created between the two devices.

NoTe

The default setting for the ”link fault” feature is

Disabled.

The communication link offers the following advantages:

NoTe

All third-party performance and hazardous location approvals apply with and without the communication link connected.

1. Single point system diagnostics – The link offers the ability to view device variables of the receiver while connected to the transmitter, or vice versa

(using a HART handheld or Modbus device).

These variables include signal strength, status, and configuration parameters such as alarm set points, heater settings, gas type, etc.

2. Dynamic lamp power – The link enables the system to optimize lamp power per the application.

This optimization only happens during the zero calibration process.

HIStoRy LoGS

Non-volatile memory is provided in the receiver to save a record of the 100 most recent calibrations and 1000 most recent alarm/fault events. Operating temperature and voltage of the receiver are also recorded with each event log. A real time clock is provided for time stamping events. This information is accessible using

HART or Modbus communication.

INteRNAL mAGNetIC SwItCH / CALIBRAtIoN LINe teR mINAL

An internal magnetic switch is provided for resetting latched alarms and initiating field zero calibration.

See Figure 2 for switch location. The same functions can be accomplished remotely by installing a switch

(momentary closure) between the CAL and 0V COM terminals on the AutroPath HC800 receiver. Momentary switch activation will reset alarms, while holding the switch closed for three seconds or longer (not to exceed 30 seconds) will start the calibration sequence.

The LEDs will begin flashing green (5 Hz) when the reset criteria have been met and will change to flashing yellow (5 Hz) when the calibration period has been met

(>3 seconds, <30 seconds). The device will reset if the switch is released during a flashing green LED and will enter calibration if the switch is released during a flashing yellow LED.

After warm-up mode is completed, the device automatically enters the Normal mode, and all analog and alarm outputs are enabled. The AutroPath HC800 modules must be properly aligned before normal operation is attained. See “Installation” section for details.

Calibrate

After alignment is completed, zero calibration is required. Span calibration of the AutroPath HC800 is performed at the factory; however, the user has the option to verify proper calibration if necessary. It is recommended that the zero calibration procedure be performed annually. Refer to the “Calibration” section in this manual for details.

NOTE: The system must be configured for less than 60% of the full scale measuring range, with consideration to the accepted gas cloud size and concentration.

4-20 mA Current Loop output

The AutroPath HC800 provides a linear current loop output that is proportional to the detected gas level.

Fault and calibration status are also indicated by this output.

The full-scale output corresponding to 5 LFL-meters is 20 mA. HART and Modbus interfaces also have the ability to calibrate (trim) the 4 mA and 20 mA levels.

The AutroPath HC800 is equipped with output monitoring circuitry for the current loop and will indicate a fault when the output mA level does not match the output set point of the device. This monitoring (disabled by default) will indicate a fault if the current loop is not terminated correctly. The loop monitoring feature can be enabled via HART or Modbus communication.

StAtuS AND FAuLt INDICAtIoN

Status and fault conditions are indicated using the 4–20 mA analog signal output. Signaling modes include two predefined modes, and a user defined mode for third party compatibility. The user defined mode allows users to define a mA output level (range 1.0 - 3.6 mA) for each of the three status / fault categories: configuration, advisory, and detection disabled. Refer to Table 4 for status indications and Table 5 for fault conditions.

Status and fault indication configuration options can be changed via HART or Modbus communication.

(Refer to the “Troubleshooting” section for additional information regarding fault identification.)

NoTe

Transmitter warm-up and fault conditions are indicated by a solid yellow LeD, and diagnostics can be performed using HART or Modbus communication. The receiver will continue to perform its safety function, and will indicate a fault status if normal operation has been compromised.

If a transmitter fault occurs, perform normal maintenance and ensure correct input voltage at the device. If normal operation cannot be restored, return the device to the factory.

CautIon

The wiring procedures in this manual are intended to ensure proper functioning of the system under normal conditions. However, because of the many variations in wiring codes and regulations, total compliance to these ordinances cannot be guaranteed. Be certain that all wiring complies with the NeC as well as all local ordinances. If in doubt, consult the authority having jurisdiction before wiring the system. Installation must be done by a properly trained person.

CautIon

This product has been tested and approved for use in hazardous areas. However, it must be properly installed and used only under the conditions specifi ed within this manual and the specifi c approval certifi cates. Any device modifi cation, improper installation, or use in a faulty or incomplete confi guration will render warranty and product certifi cations invalid.

CautIon

The system contains no user serviceable internal components. Service or repair should never be attempted by the user. Device repair should be performed only by the manufacturer or trained service personnel. lIaBIlItIES

The manufacturer’s warranty for this product is void, and all liability for proper function of the system is irrevocably transferred to the owner or operator in the event that printed circuit boards are removed or the device is serviced or repaired by personnel not employed or authorized by manufacturer, or if the system is used in a manner not conforming to its intended use.

CautIon observe precautions for handling electrostatic sensitive devices.

NoTe

The AutroPath HC800 is intended for detection of hydrocarbon vapors only. The device will not detect hydrogen gas.

NoTe

The terminal compartment for AutroPath HC800 without relays is designed for either an increased safety “e” termination or a fl ameproof “d” termination of the supply cable. If a fl ameproof connection is chosen, then an ATeX certifi ed cable entry device must be used. The AutroPath

HC800 with relays requires ex d cable entry devices only. inStallation

IDentIFICAtIon oF VApor(S) to Be DeteCteD

It is necessary to identify the fl ammable vapor(s) of interest at the job site in order to determine the proper calibration gas setting for the AutroPath HC800. In addition, the physical and fi re hazard properties of the vapor, such as vapor density and fl ashpoint should be identifi ed and used to assist in selecting the optimum detector mounting locations within the area.

The detector must be installed by qualifi ed personnel only, following local electrical equipment installation practices.

SyStem LoCAtIoN CoNSIDeRAtIoNS

The AutroPath HC800 system is designed for installation in hazardous industrial areas. Each module is normally installed using a solid vertical steel post or fl at surface mounting adapter to support the weight of the module. The modules must be strategically located so that the hydrocarbon vapor(s) to be detected will intersect the light beam generated by the transmitter module. Dispersion characteristics and behavior of the vapor cloud resulting from a gas leak can be diffi cult to estimate due to the signifi cant number of variables that exist at different applications. Identifi cation of expected gas leakage source(s), leak scenario identifi cation, determination of prevailing wind direction, and onsite leak simulation are the steps generally recommended to provide the most accurate means of identifying optimum system installation locations.

In all cases, the beam path and surrounding area should be kept free of obstructions that could block the infrared beam or hinder the free movement of air within the area. A clear beam path of 20 cm diameter or greater is required. The system is immune to the effects of exposure to both direct and refl ected sunlight.


P/N 95-8744, v4.2 , rev. 3/16


Page 14

Avoid installation in areas with obstructions such as steam vents and plumes, smoke stacks and chimneys, walkways and personnel areas, splash and sprayed water, parking, loading, cranes, vehicle-related areas such as bus stops, road junctions, and vegetation such as trees, shrubs, grass etc.

Contact Autronica Fire and Security if guidance on optimum installation locations is required. Additional guidance on the positioning of gas detectors for optimum coverage is contained in BS6959 and other national codes. Consult these codes of practice when determining where detectors are to be located.

For redundant systems, spacing between units should be a minimum of 3 ft (1 meter) and the receiver should be set back from the transmitter a minimum of 12 inches

(30 cm) as shown in Figure 7.

System Mounting Elevation

In all cases, the modules should be installed at the same elevation above grade to ensure that alignment capability and foul weather performance are not compromised.

For detection of lighter than air vapors such as methane, installation of modules at approximately 2 meters above grade minimizes typical beam block conditions due to human activities, while enabling satisfactory detection capability. For detection of heavier than air vapors, installation of detectors below the expected leakage source is generally recommended unless nuisance beam blocks will occur at an unacceptable rate. In this case, identification and analysis of application specific conditions should be completed to determine the optimum installation elevation.

Consideration of the following system location guidelines is also recommended. Routine maintenance is recommended after abnormal events.

Module Separation Distance

The transmitter and receiver modules must be installed directly facing each other across the area to be protected. Physical obstructions in the direct line of sight between the modules are not permitted. The overall line of sight distance between the modules must not fall outside the specified operating distance range (refer to the “Specifications” section of this manual for details).

Sources of Heavy Contamination

Avoid locations where high levels of contaminants will persistently be blown onto the detector windows. Potential sources of heavy contamination include generator / turbine exhausts, flare stacks, drilling equipment, process vents / chimneys, etc. If sources of heavy contamination cannot be avoided, consider fitting extra shielding and/or providing good access for routine cleaning.

LED Visibility

Whenever possible, select a mounting orientation where the status indication LED is visible to personnel within the area.

Multiple System Installations

If multiple AutroPath HC800 systems are to be installed, ensure that each receiver can view only the intended transmitter. For fence line applications, the recommended order is Tx-Rx, Rx-Tx, Tx-Rx, etc. as shown in Figure 6.

The AutroPath HC800 provides the option to turn off the Green LED in the Normal mode when no alarms or faults are occurring. When configured for OFF mode, the green LED will turn OFF after a specified period of time. The default is 60 seconds, with a selectable range from 30 to 600 seconds.

Do NOT expect the LED to turn off immediately after changing the setting. Also note that momentary closure of the magnetic switch, fault clear, and alarm clear will reset the OFF mode timer, and the green LED will remain lit for the selected time delay period.

This option is selected from the “Gen Configuration” screen using HART communication.

Snow and Ice in Ambients Below –20°C

The heated optics on both modules will melt snow or ice on the windows in ambient temperatures down to approximately –20°C. Below this temperature, snow or ice blown onto the window will not be melted until the ambient temperature rises. If long term outdoor operation in very cold climates is intended, extra shielding / covers are recommended to prevent accumulation of snow and ice on the windows. moDuLe mouNtING ReCommeNDAtIoNS

AutroPath HC800 modules must be affixed to a solid, non-vibrating structure capable of supporting a minimum of

100 lbs (46 kg), located within the system’s rated separation distance.

A building wall, a heavy steel wood structures or supports if the possibility of warping exists.

i -beam, or nearly any type of masonry typically provides the most rigid mounting surface available. However, avoid the use of

Deluge and Flooding

The modules are rated IP66/IP67 and will not be damaged by occasional deluge or flooding. However, during such an event, the unit will completely lose it’s 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 the modules away from areas prone to deluge or flooding.

When using a vertical post, the post must be absolutely stable and without vibration. Square stock pole is recommended. Mounting height should not exceed 3 meters.

The post can be set into the ground or attached to a secure surface. If a post is set into the ground, the portion below grade should be set in concrete at least

1 meter deep.

Areas Prone to Subsidence and Settling

Avoid installation of the modules in areas where problems with subsidence, settling or thawing of permafrost can occur or cause significant movement.

If such locations cannot be avoided, the foundations of the mounting structure should be engineered to minimize any angular movements between the receiver and transmitter.”

Important

In all cases, consider whether additional bracing or support is needed to ensure the structural integrity of the module installation. See Figure 8. Remember that accurate module alignment is essential for proper performance of a line of sight gas detection system. Movement may have a detrimental effect on alignment. This is especially true for installations with significant module separation distances.

Areas Prone to Earthquakes

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

Module mounting options include:

• A vertical or horizontal post with a nominal outside diameter of 4.5” (11.43 cm). Acceptable outside diameter range is 4” to 4 5/8” (10.16 to 11.75 cm).

See Figure 8.

• For flat surface mounting, refer to Figure 10.

Misalignment by Accidental Impact

Locations where there is a significant likelihood of equipment, personnel or moving objects accidentally knocking the modules out of alignment should be avoided where possible. If such locations cannot be avoided, measures including improved mechanical protection and warning notices should be considered.

Anti-seize material (provided) must be applied to the U-bolt threads at the time of installation to prevent galling.

NoTe

NoTe

To ease installation and future removal, all threaded covers, stopping plugs, and thread adapters must be installed using thread lubricant.

See “ordering Information” for part number — avoid the use of silicone grease. For devices with

NPT threads, Teflon tape or thread seal lubricant must be used for enhanced sealing capability. A minimum torque of 20 foot-pounds is required to maintain ingress protection. To maintain the IP or

NeMA ratings when using NPT stopping plugs, one to three wraps of Teflon tape is required.

1. To ensure proper operation, AutroPath HC800 power terminals and 4–20 mA terminals must receive 18 Vdc minimum. 24 Vdc is recommended.

AC voltage should not be switched directly using the

AutroPath HC800 relays. The use of an external relay is required if AC voltage must be switched by the

AutroPath HC800 relays. Note: External relay is not covered by any Certifications.

2. Always determine voltage drops that will occur to ensure that 24 Vdc is delivered to the AutroPath

HC800.

In order to change alarm relay settings from the factory default settings, it is recommended to use a HART

Field Communicator. Contact the factory for further assistance.

3. Normally, nothing smaller than 18 AWG (1.0 mm 2 ) is recommended by Autronica Fire and Security for

AutroPath HC800 power cabling.

Wire size requirements are dependent upon power supply voltage and wire length.

NoTe

Refer to “Alarm Relays” in the “Specifications” section of this manual for important information regarding alarm relays.

The maximum distance between the AutroPath HC800 detector and its power supply is determined by the maximum allowable voltage drop for the power wiring loop. If the voltage drop is exceeded, the device will not operate. To determine the maximum power loop voltage drop, subtract the minimum operating voltage for the device (18 Vdc) from the minimum output voltage of the power supply.

wIRING PRoCeDuRe

For systems using conduit, modules must be wired using a short piece of suitable flexible conduit to allow optical alignment of the modules. Conductor insulation should be stripped off with a bare conductor length of 0.2 inch (5 mm) minimum and 0.35 inch (9 mm) maximum. Screw terminal torque range is 3.5–4.4 lb.in. (0.4–0.5 N•m).

To determine the actual maximum wire length:

1. Divide the maximum allowable voltage drop by the maximum current draw of the AutroPath HC800

(0.771 A),

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 detector housing or any other wire.

2. Divide by the resistance of the wire (ohms/foot value available in wire manufacturer’s specification data sheet),

Figure 14 shows the wiring terminal strip located inside the detector’s integral junction box.

3. Divide by 2.

For example: Consider an installation using 18 AWG wiring with a power supply providing 24 Vdc.

NoTe

The AutroPath HC800 housing must be electrically connected to earth ground. A dedicated earth ground lug is provided for this purpose.

Power supply voltage = 24 Vdc,

AutroPath HC800 minimum operating voltage = 18 Vdc

Figure 12 shows the wiring terminal configuration for the AutroPath HC800 transmitter.

24 – 18 = 6 Vdc

Figure 15 shows the wiring terminal configuration for the AutroPath HC800 receiver without relays.

Maximum Voltage Drop = 6

Maximum Current = 0.771 A

Wire Resistance in Ohms/Foot = 0.006523

Figure 13 shows the wiring terminal configuration for the AutroPath HC800 receiver with relays.

6 ÷ 0.771 ÷ 0.006523 ÷ 2 = 596 feet

Figures 16 through 19 show the 4–20 mA output of the

AutroPath HC800 receiver in various wiring schemes.

oPtIoNAL ReLAyS

Optional relay contacts are “dry,” meaning that the installer must provide the voltage to the common terminal of the relay output.

See Figure 20 for benchtop test wiring.

NoTe

For proper HART communication, it is required that an analog signal loop resistance of 250 to

500 ohms be present at the receiver analog output terminals. For AutroPath HC800 systems using HART communication, the maximum wiring distance is 2,000 feet. No external resistance needs to be added to the transmitter wiring for proper HART operation.

A pair of HART connector pins is provided for ease in connecting a HART handheld device. See Figure 22 for location.

NoTe

To establish the optional “communication link” between the transmitter and receiver, connect a three-wire shielded cable to the INTR A, INTR B, and INTR GND terminals of the two devices. See

Figure 21. Take care not to connect any of these lines to 0V CoM. Doing so will damage the 4–20 mA circuit and make the device susceptible to surge.

When the AutroPath HC800 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, HART communication will be required.

NoTe ensure that alarm devices are bypassed during commissioning.

NoTe

The safety function (gas input-to-actuation/ notification) must always be verified upon completion of installation and/or modification.

aliGnMEnt oVeRVIew

The AutroPath HC800 modules must be properly aligned before normal operation will be attained.

NoTe

Refer to the ATeX or IeCex Appendix for information regarding the effect of misalignment on system accuracy.

equIPmeNt RequIReD

1. Properly installed and powered AutroPath HC800 system (transmitter and receiver). Easy access to both modules is highly recommended.

2. AutroPath HC800 Alignment Tool. The alignment tool is recommended for use in commissioning all

AutroPath HC800 systems. The following instructions cover the use of the Alignment Tool.

3. 9/16 inch wrench.

4. 15/16 inch wrench.

5. For installations with short separation distances

(5-15 meters for the short range model and 30-40 meters for the long range model), the short range aperture kit (supplied) is typically needed. Refer to

“Aperture Kit for Short Range Applications” section of this manual for details.

ALIGNmeNt PRoCeDuRe

1. Ensure that the system modules are located within the specified separation range and securely fixed to the support structures. Bypass all external gas alarm devices that are connected to the receiver outputs.

2. Ensure that the system modules are installed with their windows at approximately the same height above grade. Each module should be roughly aligned to face in the direction of the other module.

3. Loosen the Horizontal and Vertical Adjustment

Bolts on the mounting and alignment bracket using the 9/16” wrench for the Horizontal Adjustment

Bolts and the 15/16” wrench for the Vertical

Adjustment Bolts. See Figure 23.

4. Loosen the four Horizontal Locking Bolts on top of the mounting and alignment bracket using a 9/16” wrench, then retighten until just snug against the top plate of the Detector Mounting Assembly. The

Detector Mounting Assembly should still be able to rotate on its axis when adjusting the Horizontal

Adjustment Bolts. If not, slightly loosen the four

Horizontal Locking bolts.

6. Install the Alignment Tool onto the receiver module by inserting the captive thumbscrews into the threaded holes on the faceplate. See Figure 24.

Ensure that the alignment tool is properly attached, that the eyepiece is accessible, and that the thumbscrews are completely tightened.

7. Using the Horizontal and Vertical Adjustment Bolts, adjust the receiver module as required until the cross hairs are centered as close as possible to dead center on the window of the transmitter module. Do not tighten the adjustment bolts at this time, just snug down all adjustment bolts finger tight.

8. Slightly loosen the Vertical Adjustment Bolts so that tightening the 4 Horizontal Locking Bolts does not cause the Detector Mounting Assembly to bind as it is being pulled up.

9. Tighten the 4 Horizontal Locking Bolts in an opposing-alternating pattern. Torque each bolt to

200 in-lbs (22.6 N•m) maximum.

10. Tighten the Horizontal Adjustment Bolts to 200 inlbs (22.6 N•m) maximum, being careful to tighten each bolt evenly against each other to prevent torquing of the Detector Mounting Assembly. Tighten the

Locking nuts to 200 in-lbs (22.6 N•m) maximum .

The mounting and alignment bracket is now secured horizontally.

Figure 24— autropath Hc800 with alignment tool installed

B. Return the scope to its original position (rotate

180°) and repeat steps 7 through 13 until correct alignment is achieved.

14. Repeat the alignment procedure for the transmitter module (steps 3 to 12).

11. Verify alignment using the Alignment Tool. The

Vertical alignment may have shifted slightly due to tightening of the 4 Horizontal locking bolts pulling the Detector Mounting Assembly up. Adjust the vertical alignment if needed using the Vertical

Adjustment Bolts.

15. Re-check the alignment one final time using the alignment tool and adjust as needed.

16. Remove the Alignment Tool and re-install the brow.

12. When proper alignment has been achieved, tighten the Vertical Adjustment Bolts and Locking Nuts to 90 ft-lbs (122 N•m) maximum, being careful to tighten each bolt evenly against each other to prevent torquing of the Detector Mounting Assembly. The

Receiver is now secured vertically and aligned with the Transmitter.

17. Bypass all external gas alarm devices that are connected to the receiver outputs, and then apply

24 Vdc power to the modules.

18. Upon completion of warm-up mode (approximately two minutes or less), the receiver should produce a 4 mA output signal and a green LED indication.

If not, the required zero calibration step below may resolve this issue.

13. Rotate the telescope alignment tool by 180° and verify that the cross hairs are in the same position.

If the cross hairs are not in the same position, the telescope alignment screws must be adjusted as follows:

19. For installations with module separation distances between 5 and 40 meters, install the aperture as described in the “Aperture Kit for Short Range

Applications” section.

A. Adjust the telescope alignment screws until the cross hairs are midway between the original position (center of transmitter window) and the current position (after the scope was rotated 180°).

See Figure 25.

20. Perform a zero calibration. (Refer to “Zero

Calibration” in the “Calibration” section of this manual.) Any faults that may be present as a result of the alignment process should be cleared.

The AutroPath HC800 transmitter lamp output intensity is automatically optimized during the zero calibration process if the communication link wires are attached between transmitter and receiver. If no communication link is installed, the transmitter lamp output can be adjusted via

Modbus or HART connection to the transmitter.

This adjustment is rarely needed. (See

“Transmitter Lamp Voltage” section for more information.)

21. Proper operation should be confirmed by bypassing all system alarms, then placing an optical test film (sold separately) into the light beam and checking for the appropriate 4–20 mA output level or relay actuation. The AutroPath HC800 test film packet consists of five separate test films. Table

7 shows the response of the different AutroPath

HC800 gas settings to each of the five test films.

Alarm conditions, if present, should clear when the test film is removed from the beam.

23. When Basic Alignment and Zero Calibration have been successfully completed, a green LED should be displayed on the receiver module and the analog signal output level should be 4.0 milliamperes.

Procedure for System Commissioning Using the

Aperture

1. Align the AutroPath HC800 system using the

Basic Alignment procedure. At the completion of this alignment, the output signal at the receiver may indicate a fault condition as a result of signal saturation.

2. Attach the aperture to the front of the AutroPath HC800 transmitter module using the captive screws provided.

For best weather protection, the aperture hole should be located at the top of the unit.

Procedure

1. Connect the handheld HART communicator to the receiver module’s 4–20 mA circuit.

2. Turn on the HART communicator and check for

AutroPath HC800 device recognition. When HART communication is established, the AutroPath

HC800 Online menu will be displayed on the communicator display.

3. From the Online menu, navigate to the Detector

Setup menu, then select the Sensor Setup menu.

3. Perform a zero calibration. After performing the zero calibration, the receiver module should display a normal condition (green LED) and a steady 4 mA output.

4. The following screen will be displayed. Observe the level indicated for “Gain.”

The AutroPath HC800 does not use Intrinsically Safe circuitry for connection to the HART 475 Communicator.

Connecting a HART 475 Communicator to the

AutroPath HC800 may invalidate the Intrinsic Safety circuits of the HART 475 Communicator.

5. Table 8 can be used as a guideline for new installations to assess the detector gain level with proper alignment.

• The HART communication device must include the

AutroPath HC800 device descriptor (DD) software menu. The use of HART communication devices without the proper DDs may establish generic mode

HART communication, but will not enable proper operation with AutroPath HC800. Refer to the HART

Appendix for additional information.

• A minimum level of understanding with regard to the operation and navigation of the HART communicator is required. Please refer to the appropriate HART communicator instruction manual for basic operating instructions if required. Additional information on the use of the HART communicator is provided within the

HART Appendix in this document.

• For proper HART communication to occur, it is required that a 250-500 ohm resistive load be present in the

AutroPath HC800 analog 4–20 mA signal loop output.

6. Verify the gain setting. The gas gain setting options are 1, 2, 5, 10, 20, 50, and 100; ideal gain settings are 2, 5, and 10.

A gain of 1 indicates that the system may be near saturation (signal strength is too high). If the gas gain number = 1 and the Active avg or Ref avg numbers are greater than 1500, use the aperture kit to reduce signal. See the “Transmitter Lamp

Voltage” section for additional signal strength reduction options as needed. If using the Long range receiver, it may be necessary to switch to the Short range version.

A gain of 20 or greater indicates that the system signal strength is less than expected. Ensure that the system has a clear beam path, clean windows, and was properly aligned and calibrated in clear weather. See the Transmitter Lamp Voltage section for additional signal strength increase options as needed. If using the Short range receiver, it may be necessary to switch to the Long range version.

calibRation

CALIBRAtIoN oVeRVIew

Span calibration is not required. The AutroPath HC800 supports non-intrusive field zero calibration, although routine calibration is normally not required. zeRo CALIBRAtIoN

Zero Calibration is a one-step process consisting of clean air (zero) condition adjustment only, which is performed automatically by the device. This procedure adjusts the

“clean air” signal output only, and is normally used if the gas output signal level has drifted. The cause of drift is typically due to the presence of background gas during calibration. Additionally, the zero calibration procedure will optimize the transmitter lamp output intensity if the optional communication link is installed. This is useful for situations where the signal strength at the receiver is too large (saturation) or too small. Ensure that the optical path is clear of hydrocarbons prior to calibration initiation to ensure an accurate zero (clean air) condition.

Contact the factory for further information or assistance.

In all cases, a green LED and 4 mA output indicate that the unit will properly perform its safety function. Gain adjustments and checks are simply a way to optimize the system so that it will perform in the widest variety of application scenarios (e.g., shifting mounts, inclement weather, mechanical impact, lens obscuration, etc.).

ImPoRtANt CALIBRAtIoN NoteS

NoTe ensure that the detector has been operating for at least two hours before calibrating.

Always ensure that the AutroPath HC800 optics are totally free of all hydrocarbons before initiating calibration.

NoTe tRANSmItteR LAmP VoLtAGe

The AutroPath HC800 has a feature that automatically adjusts transmitter lamp voltage during zero calibration if the communication link is connected. (This feature is disabled by default.) Alternatively, lamp voltage can be adjusted via HART or Modbus communication directly to the transmitter. The transmitter lamp voltage should be lowered to reduce signal at the receiver. Transmitter lamp voltage should be raised to increase signal at the

Receiver. The adjustment range for the transmitter lamp is 400-950 V (default = 750 V). Contact the factory for further information or assistance.

NoTe

Zero calibration cannot be performed if the detector is improperly aligned. When correct alignment is achieved, the sensor ratio (active vs. reference signals) should be between 0.8 and 1.3. To check the ratio, connect a HART handheld and navigate to:

Main > Detector Status > Sensor Info > Ratio

An out-of-tolerance ratio value typically indicates incorrect alignment or presence of background gas.

Calibration may be initiated by any of the following means:

• The onboard magnetic calibration switch

• Digital communication via HART (see HART appendix) or Modbus communication (consult factory for details)

• Remote calibration line.

CALIBRAtIoN SequeNCe

1. Initiate calibration using one of the methods listed above:

A. The LEDs continue to flash yellow at 5 Hz.

B. The current output decreases to 1 mA, 2.2 mA, or as configured by the user.

Upon initiation, the AutroPath HC800 automatically performs the zero calibration adjustment, and then signals with a green LED when this operation is complete.

2. When zero calibration is complete:

A. The onboard LEDs change from flashing yellow to steady green.

B. Calibration is complete and the current output returns to 4 mA.

NoTe

Calibration will time out if unsuccessful after 10

Calibration Using Magnetic Switch

The AutroPath HC800 receiver provides an onboard magnetic calibration/reset switch for non-intrusive calibration capability. The magnetic switch is actuated by holding a calibration magnet at the specified location on the device bulkhead. See Figure 2 for switch location. An onboard multi-color LED provides status indication during calibration. setting.

NoTe

To abort an in-process calibration, repeat the calibration initiation sequence (e.g., hold the magnet for three seconds or more and release).

The device will revert to its previous calibration

To initiate calibration, hold the calibration magnet against the side of the receiver at the location shown in Figure 2. Apply the magnet for 3 to 30 seconds and release while the LEDs are flashing yellow at 5 Hz.

Calibration Using Calibration Line Terminal

The calibration / reset function can be accomplished remotely by installing a switch between the CAL and 0V

COM terminals of the AutroPath HC800 receiver.

To initiate calibration, short the CAL and OV COM terminals for 3 to 30 seconds and release while LEDs are flashing yellow at 5 Hz.

WarnInG

Do not open cover when an explosive gas atmosphere may be present.

FuNCtIoNAL CHeCkING

Functional checks should be performed as required by site conditions and local regulations. For specifi c approval requirements regarding functional checks, see appendices and the AutroPath HC800 safety manual.

NoTe

Refer to the AutroPath HC800 Safety Manual for specifi c requirements and recommendations applicable to the proper installation, operation, and maintenance of all SIL-Certifi ed AutroPath

HC800 IR gas detectors.

Autronica Fire and Security provides two functional check options for the AutroPath HC800. The in step 20 of the basic alignment procedure. test fi lm method provides a basic functional check as described

RoutINe INSPeCtIoN

The AutroPath HC800 detector should be inspected periodically to ensure that external obstructions such as plastic bags, mud, snow, or other materials do not block the path and thereby impair the performance of the device.

Alternatively, the gas test cell method can be used for a more precise output verifi cation. The gas cell is typically used to verify the factory calibration of the

AutroPath HC800. The gas cell has a known optical length and has infrared transparent windows on both ends. When fi lled with 100% v/v gas, it contains a specifi c LFL-m amount of gas. When the gas cell is placed in the beam of the detector, the output will rise to a specifi c value.

oPtICS CLeANING

Cleaning of the AutroPath HC800 optical surfaces is normally required only if an optical fault is indicated.

Thoroughly douse both window surfaces using a liberal amount of isopropyl alcohol to clear away contaminant particles. Repeat the alcohol fl ush to remove any remaining contaminants.

The gas cell is not intended for routine use. It does, however, demonstrate in a very direct way the response of the detector to hydrocarbons along with the resulting control action. This is particularly useful when required by regulatory authorities. See the gas cell instruction manual for further details and use instructions.

WarnInG

Bypass/Inhibit: Volatile organic compounds in cleaning solutions could cause false alarms.

PRoteCtIVe CAPS AND CoVeRS

Ensure that the wiring compartment cover is installed and fully engaged.

A Fault status is indicated by a yellow LED and also by the 4–20 mA output. Refer to Table 9 for assistance in correcting malfunctions with the AutroPath HC800

Detector.

table 9—troubleshooting Guide

Fault Condition

Low 24 volts

Corrective Action

24 Vdc operating voltage is out of range. Verify proper wiring to the detector and correct voltage output from the power source. Power supply faults are self-clearing when the condition is corrected.

If the fault does not clear, consult the factory.

Dirty Optics

Perform cleaning procedure, then recalibrate as required. (Refer to “Maintenance” for details.)

Calibration Fault

Negative Signal Output

Calibration line active at startup

Signal Saturation

EE Error

Other Faults

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

This fault is indicated when the signal output drops below –0.5 LFL-m. Normally detection capability is not compromised in this condition.

The device was probably zero calibrated with background gas present.

If the condition persists, purge with clean air and repeat the zero calibration. Ensure that the heaters are on and the windows are not fogged.

The only way to clear this fault is to correct the wiring and reapply power.

Be sure that the calibration line is not shorted and that the calibration switch is open. If the fault does not clear, consult the factory.

Add aperture to the transmitter module or adjust lamp voltage if needed.

Return unit to the factory.

Consult the factory.

Tools Required:

– 6 mm hex wrench (transmitter)

– 5/16 inch hex wrench (receiver)

– Torque wrench capable of accurately measuring 40 inch-pounds

1. Bypass system alarms as needed, then remove 24

Vdc power from the AutroPath HC800 detector.

2. Transmitter

Remove the seven stainless steel flange bolts using a 6 mm hex wrench. See Figure 26. Take care to properly support the module as the last flange bolt is removed.

Receiver

Using a 5/16 inch hex wrench, loosen the locking set screw. Turn the retainer ring by hand to loosen the module. See Figure 27.

5. Line up the pin on the replacement module with the hole in the bulkhead and insert the module straight into the bulkhead. See Figure 26 for the transmitter and Figure 27 for the receiver.

6. Transmitter

Insert and tighten the seven flange bolts in an opposing consecutive order in two stages — first partially tighten all seven bolts equally, and then fully tighten each bolt in an opposing order to 90 in-lbs (10.2 N•m) maximum of torque. Bolts are

M8-1.25x 16M.

CautIon

Flange bolts are critical to maintaining the fl ameproof properties of the AutroPath HC800. If replacement fl ange bolts are needed, DeC spare part number 012713-001 must be used in order to maintain the integrity of the enclosure. The use of any other bolts will void the ex d certifi cation of the AutroPath HC800.

3. Carefully remove the old module by extracting it straight out from the bulkhead.

Receiver

Fully tighten the retainer ring on the receiver module, then tighten the set screw to prevent the ring from being turned.

4. Ensure that the O-ring is present, undamaged, and correctly seated in the groove. This O-ring is required to maintain the watertight integrity of the AutroPath

HC800 housing.

8. Perform the alignment procedure as previously described in this manual.

Important

If the AutroPath HC800 module had an aperture installed, install the aperture after performing the alignment procedure (install aperture on the transmitter, not on the receiver). If the separation distance is between 5 and 40 meters and signal saturation is indicated after completion of the Basic

Alignment procedure, an aperture will be required

(even if no aperture was originally installed). Refer to the “Aperture Kit for Short Range Applications” section in this manual for complete information regarding apertures.

9. Perform a zero calibration of the detector.

DEvicE REpaiR anD REtuRn

The AutroPath HC800 IR Hydrocarbon Gas Detector is not designed to be repaired in the field. If a problem should develop, first carefully check for proper wiring, programming and calibration. If it is determined that the problem is caused by an electronic failure, the device must be returned to the factory for repair.

Prior to returning devices, contact the nearest local

Autronica Fire and Security office so that a Return

Material Identification (RMI) number can be assigned.

A written statement describing the malfunction must accompany the returned device or component to assist and expedite finding the root cause of the failure.

Pack the unit properly. Always use sufficient packing material. Where applicable, use an antistatic bag as protection from electrostatic discharge.

10. Upon completion of zero calibration, verify proper operation by performing an “optical test film test” and also a “beam block test” (see steps 20 and 21 in the “Basic Alignment Procedure” section in this manual).

NoTe

Inadequate packaging that ultimately causes damage to the returned device during shipment will result in a service charge to repair the damage incurred during shipment.

NoTe

Replacement receiver modules are furnished from the factory with default configuration settings.

If the AutroPath HC800 system has had any configuration changes in the field, the new receiver will require changes to configuration parameters using a HART communicator, a AutroVu AV10 display unit, or Modbus communication.

Return all equipment transportation prepaid to Autronica

Fire and Security.

HART COMMUNICATION

Digital communication with the AutroPath HC800 is necessary to monitor internal status and to modify the factory settings. This appendix provides guidance on establishing HART communication, and describes the communication menu structure when using the AutroPath HC800 with the HART Handheld Communicator.

INteRCoNNeCtING tHe HARt CommuNICAtoR wItH tHe AutRoPAtH HC800

Connect the HART Communicator to the AutroPath HC800. Press the “on” key to switch on the HART Communicator.

The Online menu is the first menu to appear when the Communicator is properly connected to the AutroPath

HC800. This menu is structured to provide important information about the connected device immediately on powering up the Communicator. This menu displays up-to-date device information including primary variable, analog output, lower range value, and upper range value.

NoTe

The HART protocol incorporates a concept called the “Device Description Language” that enables all suppliers of HART instruments to define and document their products in a single consistent format. This format is readable by handheld communicators, PC’s and other process interface devices that support DDL.

DDL enables full interoperability of devices, regardless of manufacturer, allowing full functionality from any

HART device.

In the event that your Communicator does not establish communications with the AutroPath HC800, you may need to ensure that the appropriate DDL’s for the AutroPath HC800 are included within your Communicator. To review the device descriptions programmed into your HART Communicator:

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

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

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

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

Communicator.

If you cannot find the AutroPath HC800 device on your Communicator, the device revision you are looking for is not programmed into the Memory Module. In this instance, you are limited to what is available using the generic interface built into your HART Communicator.

The HART Communication Foundation (www.ccsi.com/hart) manages a library of Manufacturer Device Descriptions, which are distributed to programming sites for inclusion in master devices. A complete listing of the HCF DD Library is available for download in manufacturer and device type sequence.

NoTe

If a device is found, the HART Communicator displays the online menu. If no device is found, the Communicator displays the Main menu. If no device is found, check the connections, verify the presence of a minimum of

250 ohms load resistance in series in the loop, and retry by selecting “online.” To poll multiple devices in the loop, refer to the HART Communicator manual.
