INTRODUCTION Searchline Excel is a hydrocarbon gas detection system that is available in two versions: • Searchline Excel Open-Path Gas Detector • Searchline Excel Cross-Duct Gas Detector For information regarding the Cross-Duct Excel contact Honeywell Analytics. Searchline Excel Open-Path Gas Detector (OPGD) consists of a Transmitter unit that sends an infrared beam to a Receiver unit up to 200 metres away, and can be located where a flammable hydrocarbon gas cloud is likely to occur. The detector operates on the principle of infrared (IR) absorption. Gases absorb light at specific wavelengths depending on their molecular composition. Hydrocarbon gases absorb in the infrared region of the spectrum. If a cloud of hydrocarbon gas is present, part of the infrared light is absorbed by the gas, causing a reduction in the signal received that is proportional to the amount of gas in the beam. The Searchline Excel Transmitter unit produces the infrared light, and the Receiver unit features optical detectors and signal processing electronics. Each unit is housed in a robust stainless steel housing. The Receiver produces a 4 - 20mA analogue output equivalent to 0 - 5 LEL.m (Lower Explosive Limit metres) of gas. NOTE: THE INFRARED BEAM IS INVISIBLE AND EYE SAFE Searchline Excel is designed for use in the most demanding environments/applications and provides a sensitive, fast and reliable response. The sophisticated open-path technology provides immunity to sunlight and minimises the effects of environmental factors such as rain, fog, ice, snow and condensation. The Transmitter and Receiver units incorporate heated optics designed to minimise the build up of humidity, condensation, snow or ice on the glass windows, that could obscure the optics in extreme conditions. The system is microprocessor controlled with integral self-diagnostics and fault finding facilities. Local communication between an operator/technician and the gas detector system is made via an associated Handheld Interrogator that uses the Receiver’s inbuilt RS485 serial link. The interrogator provides the user with a menu-style interface to select and invoke commands for commissioning and configuring the system, and for viewing the system state and measurements. The interrogator is connected to the Receiver via one of Honeywell Analytics' DX/DVC100 (M) series types of Termination Unit, or via other types of junction box using the optional SHC Protection Device. The DX/DVC100(M) Termination Units feature an active digital interface that allows a remotely located control centre to monitor the gas detector's signal output and perform basic commands using the Modbus Remote Terminal Unit (RTU) protocol over an RS485 link. 6 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 1.

OVERVIEW 2.1 INTRODUCTION Each type of Searchline Excel gas detector consists of two units, a Transmitter and a Receiver. This separate Transmitter/Receiver configuration provides the most reliable basis for open path gas detection. DVC100(M) MK2 or DX100(M) (or other junction box) Mounting plate Mounting bracket Honeywell Analytics Junction Box 00780-A-0100 (or other junction box) Pivot block Receiver Transmitter Flexible conduit Monitored path 5 - 200 m 8 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 2. OVERVIEW There are three ranges of Searchline Excel gas detector. These are: Open-Path Short Range Medium Range Long Range 5 – 40m (15ft – 130ft) 20 – 120m (65ft – 390ft) 120 – 200m (390ft – 650ft) When designing an installation for Searchline Excel it is important that the correct range of the gas detector for each path to be monitored is selected and specified. The Transmitter and Receiver are each mounted upon robust, adjustable mounting brackets. These brackets bolt to a mounting plate, which is designed to accommodate a variety of junction boxes, accessories and mechanical mounting configurations. The small size and flexibility of Searchline Excel and its mounting arrangements are intended to make correct installation design as simple as possible. Installation details are given in Chapter 3. 2.2 TRANSMITTER The Searchline Excel Transmitter produces an intense, collimated infrared beam which is produced by a Xenon arc flashlamp. The flashlamp’s infrared output is collimated using mirrors which enables a more uniform beam (no chromatic aberrations) to be produced and hence reduces alignment sensitivity. In order to prevent annoying visible flashes, the visible emissions from the flashlamp are blocked by a filter. The Transmitter’s flashlamp is pulsed at precisely 4Hz, each pulse lasting for approximately one microsecond. The precise timing and extremely short duration of these pulses give the Transmitter a very distinctive signature. This distinctive signature makes it easy for the Receiver to distinguish Searchline Excel Transmitter pulses from both natural and artificial sources of infrared radiation. NOTE: THE INFRARED BEAM IS INVISIBLE AND EYE SAFE. The medium and long range Transmitters contain a higher power flashlamp and larger optics than the standard short range unit. The resulting infrared beam is many times brighter which allows for a considerable increase in operating range. 9 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 2. OVERVIEW 160mm (SR) 211 (MR/LR) Approximately 300mm 291mm (SR) 353 (MR/LR) 417mm (SR) 433 (MR/LR) The Transmitter window is heated to minimise condensation, frosting and the build up of snow. During particularly cold operating conditions, the heating of the Transmitter window is increased to turbo levels. The turbo mode can be disabled if not required. Electrical connections to the Transmitter are made via wires which run through the protective, flexible conduit. There are three Transmitter wires, red (+24V), black (0V) and greenIyellow (GND). 2.3 RECEIVER The Searchline Excel Receiver collects infrared radiation from the Transmitter and performs measurements to enable hydrocarbon gases in the beam path to be detected. Infrared radiation is collected by a single, silicon lens, which is common to both the sample and reference measurement channels. This radiation is divided by a beamsplitter and fed to two filtered detectors, sample and reference. The sample detector input is filtered at wavelengths where strong infrared absorption is exhibited by the target gas. The reference detector input is filtered at nearby wavelengths, where strong infrared absorption is not exhibited by the target gas. By calculating the ratio of the sample to reference signal it is possible to measure the quantity of gas in the beam, whilst compensating for the effects of rain, fog, dirt etc. 10 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 2. OVERVIEW 160mm Approximately 300mm 291mm 417mm (SR) The solid state, photovoltaic detectors used in Searchline Excel provide an exceptional dynamic range and superb temperature and long term stability. These features contribute strongly to the solar immunity and stability of Searchline Excel. The Receiver contains all of the electronics necessary to amplify, condition and process the signals received by the infrared detectors. The advanced signal processing of Searchline Excel employs two microprocessors. One microprocessor, the Digital Signal Processor (DSP), is used to perform the necessary intensive signal processing calculations. The other microprocessor, the microcontroller, controls the overall function of the unit and performs the final calculations to determine the correct gas reading and output state. The primary output of the Receiver is a signal in the range 4 - 20mA and is available as either source or sink options. For most applications, the output is calibrated for a range of 0 to 5 LEL. m. (See Appendix B for the explanation of LEL.m and other terms) The Receiver also features an RS485 output which is used to communicate with the associated SHC1 Handheld Interrogator. The SHC1 is used to perform final alignment, commissioning, functional testing and diagnostic procedures. The Receiver window is heated to minimise condensation, frosting and the buildup of snow. The level of heating applied is controlled by the microcontroller and is adjusted from zero to maximum depending on the window temperature. Electrical connections to the Receiver are made via wires which run through the protective flexible conduit. There are six Receiver wires, red (+24V), black (0V), white (4 - 20mA), orange (RS485 A), blue (RS485 B) and green / yellow (GND). 11 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 2.

INSTALLATION AND OPERATION 3.1 INTRODUCTION WARNING The national Code of Practice regarding selection, Installation and maintenance of electrical apparatus for use in potentially explosive atmospheres must be complied with at all times. Searchline Excel has been designed, engineered and customer tested to be the most robust, reliable Open-Path Gas Detector (OPGD) available to date. The design and technology employed in Searchline Excel makes it far more resistant to the adverse effects of the operating environment and non-ideal installation engineering than previous generations of OPGDs. With careful consideration of the intended operating environment and the installation design, the installer/operator can maximise the reliability, availability and performance achieved with Searchline Excel. Before designing or specifying an installation for Searchline Excel, it is strongly recommended that the installation design authority reads all of this chapter and considers how the information and recommendations provided can be applied to their installation(s). If you have any queries concerning your installation design, contact Honeywell Analytics or your local agents. Honeywell Analytics is committed to ensuring that customers achieve reliable operation of their Searchline Excel Gas Detectors. For this reason, Searchline Excel should only be installed by fully trained personnel (trained by Honeywell Analytics or a Honeywell Analytics authorised trainer). This training will provide the installer with a clear understanding of the Searchline Excel product and the associated accessories and tools. It will also provide familiarity with the installation, alignment and commissioning procedures, plus installation assessment skills to identify potential problem areas. For each installation, an installation check sheet should be completed and returned to Honeywell Analytics or their agents. Details of this check sheet are given at the end of this chapter. NOTE: THE INFRARED BEAM IS INVISIBLE AND EYE SAFE. 13 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 3. INSTALLATION AND OPERATION 3.2 SITING AND MOUNTING 3.2.1 General When designing an installation for a Searchline Excel gas detector it is important to give consideration to where it is to be located, what potential sources of problems may be encountered in this location and how the unit is to be mounted and supported. 3.2.2 Location for Best Coverage Guidance on the positioning of gas detectors to provide the best detection coverage is contained in BS EN 60079-29-2:2007 & IEC 60079-29-2:2007 and other national Codes of Practice. It is recommended that the installation designer consults these Codes of Practice when determining where detectors are to be located. In general, the following positions usually provide the best results: • • • • Below potential leak sources for gases that are heavier than air. Above potential leak sources for gases that are lighter than air. Near to leak sources, along the expected leak trajectory, taking account of the prevailing wind direction and any other factors which will influence propagation of the leak. Between possible leak sources and any potential sources of ignition. Location to Maximise Reliability and Availability Care in choosing the location of Excel detectors can contribute significantly to the overall reliability and availability. When locating units, attempt to avoid areas where they may be adversely affected by the following: Vibration - Angular vibration of the structure to which Excel units are attached should be kept to less than +/- 0.5°. Where possible, avoid locations where high levels of vibration will be directly induced into the mounting structure. If close proximity to significant sources of vibration is unavoidable, take steps to reduce coupling of this vibration and maximise the rigidity of the mounting structure. Intense Heat - Excel is certified and specified for operation in environments up to +65°C. If sources of intense heat (flarestacks, intense sunlight, etc.) are present, a sunshade (Part No: 2104B2323) or similar shield should be fitted to the unit to protect it from excessive heating. Sources of Heavy Contamination - Avoid locations where high levels of contaminants will persistently be blown onto the unit’s windows. Potential sources of heavy contamination include generator/turbine exhausts, flarestacks, drilling equipment, process vents/chimneys etc. If sources of heavy contamination cannot be avoided, consider fitting extra shielding and/or providing good access for more routine cleaning. Snow and Ice in Ambients Below -20°C - The heated optics on Excel units will melt snow or ice on the windows in ambient temperatures down to approximately -20°C. 14 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 3. INSTALLATION AND OPERATION 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, it is recommended that extra shielding/covers are employed to prevent snow/ice from being blown onto the windows and building up. Note: The heated optics have not been evaluated as part of the performance testing relating to the FM approval and therefore are not considered part of the performance approval. Deluge and Flooding - Searchline Excel is rated IP66/67 and as such will not be damaged by occasional deluge or flooding. However, during such instances the unit will completely lose its IR signal and will enter the BEAM-BLOCK/FAULT state. Also, when the deluge/flooding subsides, there is the possibility that contaminants will be left on the windows. Therefore, it is recommended that Excel units be located away from areas particularly prone to deluge or flooding. Areas Prone to Subsidence and Settling - Where possible, it is recommended that Excel units are not mounted on structures located where problems with subsidence, settling or thawing of permafrost are known to cause significant movement. If such locations cannot be avoided, the foundations of the mounting structure should be engineered to minimise any angular movements. Areas Prone to Earthquakes - In locations prone to earthquakes, there is a chance that during or after an earthquake, the units of an Excel gas detector will become misaligned with respect to each other. Provided that the Excel units do not suffer from direct mechanical impact damage during an earthquake, they should remain undamaged by such events. Anti-vibration mounts are unlikely to be of any benefit and are not recommended. After an earthquake it is recommended that Excel gas detectors are visited and their alignment be checked. Accidental Impact - Locations where there is a significant likelihood of equipment, personnel or moving objects accidentally knocking Excel units out of alignment should where possible be avoided. If such locations cannot be avoided, measures including improved mechanical protection and warning notices should be considered. Intense Electromagnetic Fields - Searchline Excel complies with EN61000-6-3:2007 and EN61000-6-2:2005 (Industrial levels) and as such is well protected from interference by electromagnetic fields. However, locations in close proximity to radio/radar transmitters, heavy electrical plant and high voltage power cables may experience field strengths in excess of those specified in EN61000-6-3:2007 and EN61000-6-2:2005. Where possible, such locations should be avoided or units should be installed as far as possible from the source of the electromagnetic field. Measures including additional screening, filtering and transient suppression may also be of benefit in such locations. 3.2.3 Beam Path The Transmitter and Receiver units windows should face each other across the area to be protected and, depending on the range of the Transmitter in use, should be the following distance apart: 15 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 3. INSTALLATION AND OPERATION Excel Gas Detector type Short Range Medium Range Long Range Path length between units 5 - 40m (15 - 130ft) 20 - 120m (65 - 390ft) 120 - 200m (390 - 650ft) The beam path and immediate surrounds should be kept free of obstructions that might hinder the free movement of air in the protected area or block the infrared beam. A clear beam path of 20cm diameter or greater is recommended. In particular, for optimum availability, avoid areas affected by the following. a. Steam vents and plumes b. Smoke stacks and chimneys c. Walkways and personnel areas d. Splash and spray, e.g. from moving equipment, cooling towers, etc. e. Parking, loading, cranes, vehicle temporary stops, e.g. bus stops, road junctions, etc. f. Vegetation, e.g. shrubs, bushes, branches, etc. - if currently clear, movement due to weather and future growth or planting must be considered Note: Where c. and d. cannot be avoided, consider indicating the beam by marking the walkway or road with paint. Unit cowl Telescope clearance arc - radius more than 50cm Beam clearance arc - radius more than 10cm Notes: 1. In order to fit the alignment telescope, used during the alignment process, a clear accessible arc of at least 50cm radius is required close to the unit’s cowling as shown. 2. A clear beam path of at least 10cm radius or greater is recommended. 16 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 3. INSTALLATION AND OPERATION 3.2.4 Supporting Structure The Transmitter and Receiver units should be fixed to a stable supporting structure using the mounting plates supplied. Note: The maximum movement of the supporting structure under all anticipated operating conditions must be ±0.5o. If either unit is to be free standing and not mounted to existing supports or structures, and the height above the ground is no more than 3m, the supporting structure shown is recommended: 150mm dia. steel pipe, nominal 6mm wall thickness Excel mounting plate U-bolts 8mm dia. 166mm centres Up to 3m 500mm minimum 500mm minimum 500mm minimum Concrete foundation Note: The pipe can be filled with concrete to provide extra robustness if necessary. 3.2.5 Orientation Searchline Excel is solar immune and therefore there is no need to take account of the sun’s movement when considering orientation. When positioning the units do not install them with the optical axis at an angle greater than 45o to the horizontal. This is to avoid dirt/water buildup on the windows. 17 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 3. INSTALLATION AND OPERATION 3.3 ELECTRICAL CONNECTIONS 3.3.1 General All ranges of Searchline Excel comply with the EMC requirements EN50270. In order to maintain compliance with these standards it is essential that the electrical installation of Excel is engineered correctly. Electrical installation standards vary for different countries, companies and applications and it is the responsibility of the installation design authority to determine the applicable standards and ensure compliance with them. When designing electrical installations for Excel, Honeywell Analytics recommend that the installation design authority considers the following: a. The unit cases should not, if possible, be connected to electrically noisy (dirty) metalwork or conductors. Preferably, the case (internally connected to the green/yellow GND wire) should be connected to a low noise instrument (clean) earth. See also para e. below. In order to facilitate electrical isolation of the Searchline Excel from a noisy earth an isolation kit is supplied. This kit should be fitted as standard unless local regulations forbid this. b. The entire length of the field cabling connected to each unit should be fully shielded. This should be connected to a low noise (clean) earth. c. The low noise instrument (clean) earth system should only be connected to safety earth (usually dirty) at a single point on the entire site/installation. This connection should be made in such a manner that it does not introduce noise onto the low noise instrument earth. Star earthing arrangements minimise earth current crosstalk. d. The shields of the field cabling should not be connected such that earth loops are produced, or in a manner that will result in the shields carrying large currents from heavy plant or equipment. e. Ideally, the field cable shield should be connected to the unit’s green/yellow GND wire, providing a single, continuous earth shield. This connection must not be allowed to complete an earth loop. f. The earth bonding arrangement must ensure that the maximum peak voltage between the unit case earth and any field cable conductor is less than 350V. Voltages in excess of this can cause permanent damage to the unit’s RFI protection filters. g. The use of a single, screened cable for each gas detector ensures maximum screening and minimum crosstalk. Cabling arrangements which use a single cable for connecting a number of field devices compromise screening, increase the potential for crosstalk and prevent implementation of true star earthing. h. Any electrical interference induced onto the 4 - 20mA loop conductors by the installation must be kept below the levels necessary to comply with the general requirements of EN 60079-29-1:2007 &, IEC 60079-29-1:2007. In practice, this means that peak noise currents induced on the current loop should be no greater than ± 0.25mA j. The 0V rail of the control card/control system is directly connected to one side of the 4 - 20mA current sensing resistor. Electrical noise on this rail is therefore directly connected to the 4 - 20mA input. In order to avoid additional noise being induced on the 0V rail, it should not be commoned with the safety earth/ground, which frequently carries a high level of electrical noise. 18 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 3. INSTALLATION AND OPERATION k. All electrical equipment connected to the gas detector should comply with EN61000-63:2007 and EN61000-6-2:2005. l. The 24V supply should be free from large transients and fluctuations. m. The field cabling conductors should have sufficient cross sectional area to ensure that the minimum supply voltage applied to the gas detector is 18V at a current of 420mA. This corresponds to a maximum round loop impedance of 14 ohms for a nominal 24V system supply. n. Receivers should not be installed in close proximity to the antennae of high powered radio, radar and satellite communication equipment. The following diagrams show typical earth bonding arrangements for various installations. 3.3.2 Receiver Connections via DVC100(M) MK2 The earth bonding arrangement must ensure that the maximum peak voltage between the unit case earth and any field cable conductor is less than 350V.

This means that during conditions of low ambient temperature, additional heating power is applied to the unit’s window to minimise condensation, frosting and snow buildup. If the application/installation does not require turbo heating, reduced power consumption can be achieved by disabling this mode. The turbo heating is disabled by reversing the power supply connections to the Transmitter as shown in the following diagram. All other connections remain the same. 23 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 3.

INSTALLATION AND OPERATION Receiver Transmitter Note: For information about alternative types of junction box see section 3.6.2 Electrical Installation. (11) Measure and record the distance (in metres) between the Transmitter and Receiver units. This distance is required later in the alignment procedures. 3.6.2 Electrical Installation (1) Isolate all associated power supplies and ensure that they remain OFF until the instruction in the commissioning procedure to apply power. See section 3.7 Alignment and Commissioning. If the units are to be installed with junction boxes other than DVC/DX100(M) types, ensure that the boxes have: a. b. M20 cable gland entries for ATEX/IECEx units, or 3/4 NPT for UL and CSA terminals for five wires and an earth. (2) Remove the M20 blanking plugs (if fitted) and attach the Searchline Excel Transmitter and Receiver cables to their junction box. Fit the locking rings (if supplied) before terminating the cables in the junction box. (3) Fit approved cable glands to the junction box cable entries. Use sealing washers where necessary to maintain the ingress protection rating. (4) Fit approved blanking plugs to all unused cable entries. (5) Make electrical connections. See section 3.3. 32 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 3. INSTALLATION AND OPERATION 3.7 ALIGNMENT AND COMMISSIONING WARNING Do not attempt to view the Sun through the optical telescope. 3.7.1 General In order to avoid unnecessary problems, alignment and commissioning of Searchline Excel gas detectors should only be performed by personnel trained by Honeywell Analytics. To ensure optimum performance the gas detector Transmitter and Receiver units must be accurately aligned with a clear line of sight between them. The Transmitter unit is first aligned with the Receiver using a telescope attached to the body of the unit. A telescope is then fitted to the Receiver and the alignment procedure repeated. The Handheld Interrogator is then attached to the Receiver to finally commission the equipment and, depending on the type of Receiver, may need to be used to assist in fine-tuning the alignment. The procedure can be performed by a single technician. Each gas detector unit features a mounting assembly that allow both coarse and fine mechanical adjustment in the horizontal and vertical directions as shown in the subsequent diagram. Clamp nuts Mounting bracket adjusting screw (2 off) Adjustment clamp lock screw (2 off) Pivot block adjusting screw (2 off) Clamp nuts Mounting bracket adjusting screw (2 off) Adjustment clamp lock screw (2 off) Adjustment clamp lock screw (2 off) Pivot block adjusting screw (2 off) Initial coarse mechanical adjustment is first carried out by means of large clamping nuts and with the help of an alignment telescope. 33 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 3. INSTALLATION AND OPERATION Fine adjustment is then achieved by means of mounting bracket and pivot block grubscrews which move levers on the adjustment clamps, fitted to the pivot block and unit studs, and hence the unit. After initial mechanical setup the units are powered up and the mechanical alignment can be optimised and verified electronically by means of the associated Handheld Interrogator linked to the Receiver. By entering the operating range of the gas detector the Interrogator then provides reassurance that the alignment has been performed successfully. The gas detector cannot be put into service until it is. The following equipment is used to carry out the alignment and commissioning: • Alignment Telescope(s) suitable for the distance between the units (see Appendix C ‑ Accessories & Spare Parts). • SHC1 Handheld Interrogator (see Appendix C - Spare Parts). • Optional SHC Protection Device (see Appendix C - Accessories & Spare Parts) see Note 8. • Appropriate plastic test filters (see Chapter 5, section 5.1.2). • 3mm hex (Allen) key. • 19mm spanner (with additional 24mm spanner for mid/long range gas detectors). Notes: 1. Ideally, carry out the alignment procedure on a clear day. 2. Get familiar with the workings of the adjustable parts of the gas detector before proceeding with the alignment procedure, see section 3.7.4. 3. The alignment telescopes use the same datum used when the unit was aligned in the factory to ensure precise field alignment. 4. The telescopes incorporate eye relief adjustment for comfortable viewing. 5. Keep telescope mirrors and optics clean. 6. Do not try to adjust the cross-hairs using the telescope's elevation and windage adjusters as they have been factory set. 7. If a telescope is damaged or misaligned it will need to be returned to the factory for repair or realignment. 8. The SHC Protection Device is only required if connecting the SHC1 Handheld Interrogator via a junction box other than a DVC100(M) MK2 or DX100(M). 34 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 3. INSTALLATION AND OPERATION 3.7.2 Alignment Procedure The following summarises the alignment procedure: • Basic gas detector alignment, see section 3.7.3. • Accurate alignment of Transmitter and Receiver using the appropriate alignment telescope, see section 3.7.4. • Power-up and verify alignment using SHC1 Handheld Interrogator linked to the Receiver, see section 3.7.5. 3.7.3 Basic Gas Detector Alignment The basic procedure for aligning the Transmitter and Receiver units is the same. (1) Loosen the two clamping nuts and four adjustment clamp screws on the Transmitter and Receiver units until the units move freely in all axes. (2) Point the Transmitter and Receiver units so that they face each other across the area to be protected. (3) Tighten the clamping nuts and adjustment clamp grubscrews on each unit until the unit cannot be moved by hand. This is the last time that these clamp nuts and grubscrews should need to be tightened. Further tightening later on will affect the fine adjustment and should be avoided. Note: The unit can still be moved by the adjustment screws. 3.7.4 Accurate Alignment The procedure for accurately aligning the Transmitter and Receiver units is the same. Before making any adjustments consult the following table to ensure that the correct type of telescope is used with the Excel units that are to be aligned. Excel Type Type of Trident telescope that can be used SHC1 Handheld Interrogator required to finalise alignment? Trident Excel Latch-type Bayonet-type No No Non-Trident Excel Latch-type Yes To tell the difference between the two types of Excel look at the front face of the units. The Tridenttype Excel units have three small pads on their front face, the non-Trident types do not. These pads provide three contact points (hence the term Trident) for the alignment telescope assembly datum mount to ensure accurate fixing of the telescope so that subsequent alignment of the gas detector units is precise. The following diagrams illustrate the differences. 35 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 3. INSTALLATION AND OPERATION Excel unit Excel unit Alignment telescope assembly mounting pad (3 off) Trident-type Non-Trident-type After deciding from the table which alignment telescope to use for the Excel units being aligned the telescope assembly must be fitted to each of the units in turn starting with the Transmitter. There are two ways of attaching the telescope to the Excel units - using latches or using a bayonet fitting. Depending on the type supplied refer to the relevant procedure described subsequently. The bayonet style telescope is used on both the Transmitter and Receiver of the short range Excel. The bayonet-style telescope is also used on the Receiver of the medium and long range Excels. The latch-style telescope is used on the medium and long range Excel Transmitters. Latch-style telescope assembly This telescope assembly consists of a telescope and mirror assembly attached to a datum mount that features a latching mechanism. It can be used with either the Trident or non-Trident types of Excel units. When used with the non-Trident Excel the alignment may also need to be fine-tuned and then verified using the SHC1 Handheld Interrogator. The latches are used to lock the whole assembly onto the body of the Excel unit. Before securing the latches the telescope can be rotated to a convenient viewing position. To remove the telescope assembly reverse the following fitting procedure. (a) Fit the datum mount of the alignment telescope securely over the cowl of the unit as shown so that the face of the mirror is visible. Ensure the datum mount is fully home on the cowling. (b) Undo the latches on the alignment telescope's mounting latch assembly and rotate the assembly so that the parallel support bar fits underneath the unit as indicated by arrow 2. 36 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 3.

A horizontal viewing position is the easiest to interpret. Now align the units by continuing with step 5. Note: Take care when undoing the latches to remove the alignment telescope not to touch the springs. 37 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 3. INSTALLATION AND OPERATION Bayonet-style Trident-type telescope assembly Caution: This type of telescope assembly must only be used with Trident-type Excel units. This type of telescope assembly consists of a telescope and mirror attached to a datum mount. The mount features a bayonet fitting for attaching the assembly to the Excel unit. The datum mount has a handle for rotating and locking the whole assembly over the cowl and onto the Excel unit's body. Before tightening the datum mount the telescope can be rotated to a convenient viewing position. To remove the telescope assembly reverse the following mounting procedure. (a) Align the telescope's two datum mount bayonet slots with the two locating pins on the cowl of the unit as shown. Excel Unit Bayonet locating pin (2 off) Bayonet slot (2 off) Datum mount Mirror assembly Telescope viewfinder Alignment telescope Locking handle (b) Push the telescope datum mount fully home onto the two pins on the cowl. (c) Without disturbing the datum mount use one hand to rotate the telescope to a comfortable viewing position and hold it in that position. A horizontal viewing position is the easiest to interpret. 38 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 3. INSTALLATION AND OPERATION (d) With the other hand use the datum mount's locking handle to rotate the bayonet fitting in a clockwise direction until it is securely locked onto the cowl. The fitting is held tightly against the face of the cowl by means of hidden compression springs. After attaching the telescope assembly align the units by continuing with step 5. (5) Align the Excel unit using the two sets of assembly adjustment screws so that the cross-hairs viewed through the alignment telescope are centred on the window of the other Excel unit. Mirror Distant Excel unit Telescope viewfinder Cross-hairs Before alignment View the image with the eye placed approximately 3 inches from the viewfinder.

A self-test routine is started and the display shows the following message: Self Test Please Wait When the test is successfully finished the following message is displayed for at least three seconds: Checks Passed The screen then changes to show a display similar to the following. SIG: TGT: Note: If this screen shows a numerical value the alignment is not sufficient. Refer back to 3.72. The first line of the display shows the magnitude of the current signal level as a horizontal bar graph - SIG: 45 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 3. INSTALLATION AND OPERATION The second line of the display shows the magnitude of the current target signal level as a horizontal bar graph - TGT: Important Notes: 1) The overall objective of alignment is to maximise the SIG level. Maximised SIG corresponds to optimal alignment. 2) The Instrument Assisted Alignment (IAA) system only allows Excel to be initialised if the SIG level is greater than or equal to the TGT level when Enter is pressed. 3) The smallest TGT signal level that is initially set will be equivalent to 70% (0.700) of the signal expected for the installation’s path length. 4) The TGT level will increase gradually if the current SIG level is larger than the TGT level. The TGT signal level only ever increases. If the current SIG level falls below the TGT level, TGT will remain at its previous highest value. In order to initialise the gas detector the SIG level must be brought back above the TGT level. 5) If the SIG level is less than 50% of the expected level, the bar graphs are not displayed. Instead both SIG and TGT levels are displayed as numbers. (10) Now carry out one of the procedures described under Options. Options The next procedure to be followed depends on the type of alignment telescope and mounting initially used to set up the Excel gas detector. Bayonet-style Trident-type telescope assembly If this type of alignment telescope was used with a Trident-type Excel gas detector, there is no need to further optimise the alignment using the SHC1 Handheld Interrogator. When the SIG and TGT bar graphs are displayed on the SHC1 screen, SIG will always be greater than TGT and installation can proceed to the next stage by pressing Enter and following step 12. Latch-style Trident-type telescope assembly If this type of alignment telescope was used with a Trident-type Excel gas detector, there is no need to further optimise the alignment using the SHC1 Handheld Interrogator. If this type of alignment telescope was used with a non-Trident Excel it may be necessary to further optimise the alignment in the following way in order to achieve best performance. (a) After the SIG and TGT bar graphs are displayed on the SHC1 screen as previously described, let the TGT level reach its initial maximum by waiting for approximately 10 seconds. During this time the TGT level will move up towards the current SIG level. (b) (c) Whilst watching the SIG level closely, make a small mechanical adjustment in either the horizontal or vertical alignment and note whether the SIG level goes up or down. If the SIG level goes up, make another small mechanical adjustment in the same direction as before. 46 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 3. INSTALLATION AND OPERATION (d) If the SIG level goes down, change the direction of adjustment. Maximise the SIG level by making small adjustments in only one plane at a time. (e) When the SIG level has been maximised in one plane, make small adjustments in the other plane until SIG has been maximised in this plane. (f) Repeat steps (b) to (e) until the SIG level has been maximised in both planes. At this point, SIG must be bigger than the initial TGT level and any adjustment either side of the current alignment must result in a reduction in signal level. If not, repeat steps (b) to (e) until these requirements have been met. (g) Lock off the alignment by placing a hex (Allen) key in the pair of grub-screws which control adjustment in a particular plane and simultaneously rotating them in opposite directions. (h) Repeat this for the other pair of grub-screws. (i) Press Enter and the signal levels are checked. With the SIG level is greater than the TGT level, the signal check should pass and the screen should display the following message: Signals OK Notes: 1. If SIG is less than the TGT value the following message is displayed: Low Signal Enter to Retry 2. If SIG is more than the TGT value the screen shows the bar graph screen again. (12) When the following message is displayed press Enter: Signals OK The display changes to show the following instruction: Ensure Zero Gas Then Press Enter Ensure there is a gas-free atmosphere. (13) Press Enter on the keypad. The following message is displayed for three seconds: Zero Calibration OK 47 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 3. INSTALLATION AND OPERATION The following message is displayed for three seconds: Installation Complete The following message is then displayed: Press Enter to Release 4-20 (14) Press Enter on the keypad. The following message is displayed for three seconds: 4-20 Released The display then changes to show the Calibrate menu. The Searchline Excel gas detector is now on-line . This completes the final part of the gas detector alignment procedure. 3.7.6 Finishing Up To finish the alignment process carry out the following procedure: (1) Select Power Off from the Interrogator Main menu. (2) Press (Enter) on the keypad. Alternatively press the and ESC buttons simultaneously for a fast power off. Notes: 1. The SHC1 Handheld Interrogator powers down automatically after five minutes of nonuse. 2. Fast power off and auto power off are disabled when any menu option is selected that modifies the unit’s configuration. (3) Disconnect the Interrogator from the gas detector, reversing the process described at the beginning of section 3.7.5. 3.8 SYSTEM CONTROLLER CALIBRATION This procedure is used to set up the system controller using the Searchline Excel gas detector. A chosen fixed output signal is sent from the Excel gas detector to the system controller allowing calibration of the 0 - 100% scale of the controller without having to use gas. The steps use procedures described in the previous section. To calibrate the controller carry out the following procedure: (1) Connect the Interrogator to the gas detector. See Connecting the Interrogator to Searchline Excel Gas Detector. (2) Turn on the Interrogator. See Powering Up. (3) Select Calibrate from the main menu. Press the up and down keys on the keypad to navigate through the menu options. 48 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 3. INSTALLATION AND OPERATION (4) Press Enter on the Interrogator keypad and the Calibrate menu is displayed. (5) Select Force 4-20 from the Calibrate menu. (6) Press Enter on the keypad and a display similar to the following appears: > (7) > 4-20 current 4.5 mA Use the up and down keys on the keypad to set the displayed output current to the desired value. The values can be changed in steps of 0.1mA in the range 1mA to 21mA. (8) Press Enter on the keypad. This selects the currently displayed value and forces the gas detector to output that current. Once complete a display similar to the following appears: Fixed:4-20 mA Press Enter (9) Carry out checks on the controller by following the instructions in the controller documentation. (10) When checks are complete press on the Interrogator keypad and the following display appears: Press Enter To Release 4-20 (11) Press Enter on the keypad. The following message is displayed: 4-20 Released The fixed output is released and the gas detector returns to normal operation. (12) Turn off the Interrogator and disconnect it from the gas detector. 3.9 INSTALLATION CHECKS/TESTS The following information is for the guidance of personnel carrying out installation checks/tests on Searchline Excel.

INSTALLATION AND OPERATION The following notes are to help the installer enter the correct information onto the check sheet. Site/Facility Enter the name and geographical location of the site/facility, e.g. NAM F3 Platform, North Sea Operating Range Enter the distance (preferably in metres), between the Transmitter and the Receiver. Detector Location Enter the location/position of the detector, e.g. West Corridor, HIVAC Building1 Tag No Enter the Tag No, or equivalent, that has been allocated to the Excel Receiver and Transmitter units. Mod State Enter the Mod State of the units as indicated on their certification/product labels. Certification Enter the certification of the units, e.g. ATEX, UL, CSA, FM, IECEx Mount Rigidity Check that the units have been mounted securely to the supporting structure. Check that the supporting structure is sufficiently rigid to maintain alignment in the anticipated operating conditions. A maximum angular movement of ±0.5o is allowable. As an approximate guideline, a sufficiently rigid mount/supporting structure will only move a few millimetres (not more than ±6mm) when leaning body weight against it. When pushed hard and released, the mount/supporting structure should return quickly to its original position and should not wobble or sway. If the mount/ support is unacceptable, briefly describe the problem, e.g. Mount wobbles unacceptably, Mounting pole too thin Vibration Check the installation and its close surrounds for potential or existing sources of excessive vibration. Such sources could include heavy plant/machinery, turbines, generators etc. 51 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 3. INSTALLATION AND OPERATION If there is the possibility that such vibration sources could or are causing unacceptable movement, enter a brief description, e.g. Turbine nearby, Below conveyor Excess Heat Check the installation and its surrounds for potential sources of excessive heat. The unit is specified up to +65oC. Potential sources of excessive heat include direct sunlight in hot climates, flare-stacks, generator/turbine exhausts and steam vents. Enter a brief description, e.g. Direct sun, Kuwait, Flare-stack 2 metres away Supply Voltage Check that the supply voltage applied to the unit is within the specified 18V to 32V range and is stable. Enter the supply voltage and stability, e.g. 22.5V, stable, 19V, ±2V fluctuation Earthing Inspect the earth connections to the units. If the unit is connected to local metalwork or the safety/general use earth, enter 'Local Safety. If the unit has been isolated from local metalwork/ earths and is connected to a clean, instrument earth, enter Instrument earth. (See section 3.3, Electrical Connections). RFI/EMC Assess the installation, cabling and its close surrounds for known/potential sources of excessive RF/Electromagnetic Interference. Such sources could include radio/radar transmission antennae, high voltage switch-gear, large electrical generators/motors etc. Searchline Excel is extremely immune to RFI/EMI, complying with the most stringent requirements specified in EN50270. It is therefore more likely that the field cabling will pick up interference directly on the 4 - 20mA and 0V connections and that this will affect the reading received at the control room. Enter brief details of known/potential EMI sources that are within five metres of the gas detector and/or its cabling. If cable is unscreened or inadequately protected, note concerns. Examples of the sort of information to enter are: 10m cable, unscreened, Radar, 2m from Receiver, Cable routed over 400kW generator (See section 3.3 Electrical Connections). 52 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 3. INSTALLATION AND OPERATION Contaminants Assess the installation and its surrounds for sources of contaminants that could build up on the unit’s windows. Such contaminants could include oil mist, heavy sea spray, drilling mud, dirty exhaust fumes, wave splash etc. If there is a realistic possibility that such contaminants could cause a significant problem, enter a brief description, e.g. Drilling mud spray, Diesel generator exhaust Beam Obstruction/Blocks Ideally, a clear path of at least 20cm diameter should be provided between the Transmitter and the Receiver. Enter any obstructions which encroach into this path, e.g. Process pipes, Tree branches Assess the installation and the beam path for potential sources of beam blockage. These could include personnel walking in the beam, parking vehicles, moving machinery/plant, growing vegetation etc. If there is a realistic possibility that they could cause a significant problem, enter a brief description, e.g. Personnel in corridor, Loading bay vehicles Test Filter After completing the installation procedure, enter the DISPLAY mode and test the gas detector response with a plastic test filter. Enter the nominal value of the test filter, the unit’s displayed response and mark the Pass or Fail box. The acceptable responses to test filters for different gas tables are detailed in section 5.1.2. 4 - 20mA Loop Integrity Test the 4 - 20mA loop integrity by forcing the unit to output a known current and monitoring this at the control room or with a multimeter inserted into the loop. Mark the appropriate box. Fault/Warning Log Check the fault/warning log. In order for the unit to complete installation satisfactorily, the ACTIVE FAULTS log must be CLEAR. Use the Handheld Interrogator to diagnose and remedy all ACTIVE FAULT. Wherever possible, it is recommended to CLEAR any ACTIVE WARNINGS, since these may lead to faults in the future. 53 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 3. INSTALLATION AND OPERATION Faults/Warning Enter any ACTIVE FAULTS or ACTIVE WARNINGS that could not be cleared from the log, e.g. BEAM BLOCK, E_ZERO_NOT_CALIBRATED Installation Satisfactory Only fully trained personnel trained by Honeywell Analytics or Honeywell Analytics authorised trainers can declare an installation satisfactory. Mark the YES box and sign the form if: a. having completed the installation and testing, the unit is operating correctly, and b. in the trained installer's opinion, the unit should continue to operate reliably in this installation/ operating environment providing that nothing significant about the installation/environment is changed. If the unit is not operating correctly or there are aspects of the installation/operating environment which in the trained installer's opinion could or will result in unreliable operation, mark the NO box. Reasons for declaring an installation unsatisfactory could include: excessive movement/vibration of unit’s mounting, received signal levels too low, supply voltage too low, 4 - 20mA loop integrity faults, unclearable active faults, any prevailing or probable condition which is known to unacceptably reduce reliability or availability If Installation is Unsatisfactory, Reasons Briefly state the principal reasons why the installation is unsatisfactory, e.g. Unit mounted on single scaffold pole. Excessive movement, Beam path obscured by pipes, insufficient received signal levels, Unit overheated by intense Kuwaiti sunlight Recommendations Briefly describe the recommended actions which need to be performed in order to make the installation satisfactory, e.g. Mounting pole requires bracing/stiffening, Pipes obscuring beam to be moved, or detector relocated. Provide correct supply voltage Customer Notified Make sure that the relevant customer/operator is notified of the installation problem(s). Mark box accordingly. System Status Upon leaving, note the gas detectors status, i.e. operational or nonoperational. 54 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 4. MAINTENANCE The Searchline Excel Open-Path Gas Detector requires little maintenance other than occasional cleaning. Depending on the local regulations and site conditions, cleaning and functional testing of the gas detector can be carried as described in the following sub-sections. The gas detector should remain powered during these procedures. Caution: Searchline Excel does not contain any user serviceable parts. Do not open either the Transmitter or Receiver unit. The warranty of units which have been opened is invalidated. NOTE: THE INFRARED BEAM IS INVISIBLE AND EYE SAFE. 4.1 INSPECTION AND CLEANING Caution: Do not use solvents or abrasives on the Searchline Excel units. (1) Inspect the Searchline Excel units, junction box and cabling for signs of physical damage. (2) Using the SHC1 Handheld Interrogator inhibit the Searchline Excel signal output. Since the signal output may vary during cleaning, due to the optical path being disturbed, it is important to inhibit the analogue output. The quickest way to inhibit the Excel output is to select DISPLAY from the Calibration menu. (3) Clean any dust or dirt from the Searchline Excel windows using soapy water and a soft cloth. (4) Using the SHC1 Handheld Interrogator release the Searchline Excel signal output. The output can be released by pressing ESC followed by on the keyboard. (5) Using the SHC1 Handheld Interrogator re-zero the unit. See Appendix A for details about how to use the Interrogator. 4.2 FUNCTIONAL TESTING (Plastic Test Filters) From January 2004 onwards, a new range of plastic test filters has been available for performing functional testing on Searchline Excel. They are lettered from A to H, with the reading a filter produces increasing in alphabetical order. Whilst the new filters can be used with all Mod states of Searchline Excel units, they have been specifically designed to work with open path Excel units of Mod state 7 (or higher). The part number for the new test filter set is 2104N2999. Testing of Mod state 6 (or lower) open path Excel units should continue to be performed using the original plastic test filters, with the results to be anticipated detailed in Issue 8/9 of the Technical Handbook, 2104M0506. For information on testing Mod state 6 (or lower) Excel units refer to addendum 2104M0523 available from haexpert@honeywell.com. 55 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 4. MAINTENANCE The procedures for using these functional test filters on Mod state 7 or higher Excel units are detailed as follows:1) 2) 3) 4) 5) Ensure the area is free from gas. Connect the SHC-1 Handheld Interrogator to the unit to be tested. Select DISPLAY from the Calibration menu. For new units, refer to supplied test certificate for factory response to test filter recommended. For other units, slide a suitable functional test filter (see tables below) into the cowling at the front of the receiver.

This reading should be used to verify correct operation in the future. If this is not the first time that the unit has been tested with this particular filter, note the gas reading it produces and compare it to the original value recorded for this unit when tested with this filter. Provided that the reading is within ±0.5 LEL.m of the original value, the unit is working correctly. If the unit is working correctly, proceed to step 15. If the gas reading is not within the expected range it is possible that the unit needs cleaning or re-zeroing. Remove the test filter from the cowling. Using a damp, lint-free cloth, clean the windows of the transmitter and the receiver. Using the SHC-1 in CALIBRATE menu, re-zero the unit. Re-insert the chosen test filter into the cowling in front of the receiver. Verify that the reading produced by the test filter is now within ±0.5 LEL.m of the reading originally obtained with this filter. If the gas reading is still not within the expected range, check the system alignment (see section 3 of the Excel manual, 2104M0506) and repeat the test in step 7. 56 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 4. MAINTENANCE 14) 15) 16) Remove the test filter from the cowling. Release the unit under test from INHIBIT by selecting the MAIN menu option. Disconnect the SHC-1 Handheld from the unit being tested. 4.3 CALIBRATION CHECK USING THE GASSING CELL The gassing cell is designed to allow easy calibration checking using a high concentration test gas as opposed to the standard plastic test filters. The integrated LEL.m reading of the gas concentration in the cell can be calculated using the following formula: Int(lel.m)xl = Lcell * (Concgas / LELgas) where: Int(lel.m)xl = Integrated LEL.m reading output by Searchline Excel in LEL.m. Lcell = Length of cell in metres. Concgas = Gas concentration in %v/v. LELgas = Lower Explosion Limit of the gas in %v/v. The test gas must be the same as the test gas used during the factory calibration of the Searchline Excel unit and ideally the concentration should be between 2 and 5 LEL.m and never below 1 LEL.m. Note: Where a different test gas is used, the typical value for cross-sensitivity is not sufficiently precise to enable valid calibration checks to be performed using the Gassing Cell, however, response tests can be easily performed with the plastic Test Filters as described in section 5.1.2. WARNING Take the necessary precaution to ensure safety when dealing with these high concentration gasses. The gassing cell supplied by Honeywell Analytics (Part No: 2104B2326) is 0.15m long and the following table outlines the response expected when using this gassing cell: Gas type LEL Concentration of the gas applied Calculated response with 0.15m gas cell. Methane 5.0 %v/v 100 %v/v 3 LEL.m 13.6mA Ethane 3.0 %v/v 50 %v/v 2.5 LEL.m 12mA Propane 2.0 %v/v 50 %v/v 3.75 LEL.m 16mA Butane 1.5 %v/v 50 %v/v 5 LEL.m 20mA 57 4-20mA output MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 4.

Take appropriate precautions when handling. To get the best accuracy when using the gassing cell: (1) Connect the gassing cell to the Searchline Excel. (2) Zero Searchline Excel with the empty gassing cell. (3) Apply the test gas to the gassing cell and allow sufficient time to fully flush the cell without pressurising it and check that the Searchline Excel output stabilises. (4) Check the Searchline Excel output is as indicated in the above table ±5% fsd. (5) Remove the gassing cell. (6) Re-zero Searchline Excel. Note: Pentane cannot be used with the gassing cell. At normal temperatures, these substances do not vapourise sufficiently to give a useful signal in the short path of the gassing cell. 4.4 DISPLAY GAS READING This procedure displays details about the current gas/gas table. Carry out the following procedure: (1) Connect the SHC1 Handheld Interrogator to the gas detector. See Connecting the Interrogator to the Searchline Excel Gas Detector in section 3.7.6.

(2) Using a soft tissue or lens cloth, lightly wipe the lens/mirror dry with a minimum number of strokes. The wiping material may be slightly dampened with a lens cleaning fluid as sold in any camera store. 4.6 OPERATIONAL MAINTENANCE (FM) As required as a criterion for the FM Performance Approval, routine operational verification is recommended once within a three month period and is required once within a six month period using one of the following methods. WARNING The following procedure will indicate a gas reading. Ensure all required personal have been notified prior to starting and completing the procedure. 59 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 4. MAINTENANCE • Following the procedure described in section 5.1.2 insert a known test filter in the beam path. Record the response to the test filter and verify that the response is within the tolerance for stability and repeatability. • Following the procedure described in section 5.1.3, test the unit’s response to high %V/V gas in a gassing cell. Verify that the response is within the tolerance for stability and repeatability. 60 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel 5. PROBLEM SOLVING The majority of gas detector problems/faults can be diagnosed and corrected using the installation and alignment kit. The alignment kit includes: • • • SHC1 Handheld Interrogator alignment telescope set of functional test filters An electrical multimeter is also useful when diagnosing electrical/wiring problems. Refer to the troubleshooting tables in this chapter for a list of problems, possible causes and actions. Caution: Searchline Excel does not contain any user serviceable parts. Do not open either the Transmitter or Receiver unit. The warranty of units which have been opened is invalidated. NOTE: THE INFRARED BEAM IS INVISIBLE AND EYE SAFE. RS485 Modbus signal errors may occur when Excel is connected via a DVC100(M) MK2 or DX100(M) Termination Unit and is interrogated/commanded from a network control centre. For troubleshooting these issues refer to the DX100 Series Termination Units Technical Handbook. If, after following the recommendations in this section, the problem persists, please make available the following information before contacting Honeywell Analytics: • Installation Check Sheet See Chapter 3. • Any error message Displayed on the Handheld Interrogator screen. • Any error code Displayed on the Handheld Interrogator screen.

The interrogator provides the user end of a two-way communication link between the Excel system and the operator. It features facilities which let the operator configure, align, functionally test and diagnose faults in the system. The appendix gives: • an overview of the interrogator features • information about how to connect the interrogator to the Excel systems • basic user tasks, including switching on/off and changing the battery • a detailed description of the menus which the interrogator provides • problem solving information if trouble occurs when using the interrogator Details of how to use the interrogator for different tasks with the system are given Chapter 3 and Chapter 4 of this handbook. A.2 OVERVIEW The interrogator consists of an LCD screen and four keypad buttons. It links to the Excel Receiver unit via an IS connector on the end of a flexible cable connected to the associated junction box. LCD screen Up key Escape key Enter key Down key SHC1 Handheld Interrogator Main Features 83 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel APPENDIX A - HANDHELD INTERROGATOR The interrogator is powered by a standard 9V battery and has a management system which reduces power consumption by placing the unit in an idle mode when it is waiting for user input or for a communication operation to complete. The interrogator also features a 2k byte non-volatile RAM (NV-RAM) split into two sections. These sections are used to store the current operating mode and a backup copy. Liquid Crystal Display Screen This screen consists of a two-line, 16-character dot-matrix liquid crystal display (LCD). The screen displays messages which communicate information from/to the user. It displays a menu system that enables the user to select the command mode for the system, and can also display information about the system configuration and its settings, plus any error messages. Keypad Buttons The four keypad buttons are used to provide operator input in response to messages shown on the display. This includes menu option selections and changing parameter values. The four buttons are: Up Move to the previous menu option, list item, or increase a displayed data value. Down Move to the next menu option, list item, or decrease a displayed data value. ESC Escape Quit the current menu level or operation and return to the previous menu, e.g. stop displaying a list, abort a command. No change if already at the top level. Enter Select, i.e. Invoke/accept, the currently displayed menu option, list item, data value, or configuration change.

The following message is displayed: Press Enter to Align Unit This message displays the system output and reference signal values. SIG: MAX: where: A bar graph representing the current signal magnitude - SIG: A bar graph representing the target signal - TGT: Important Notes: 1) 2) 3) 4) 5) The overall objective of alignment is to maximise the SIG level. Maximised SIG corresponds to optimal alignment. The Instrument Assisted Alignment (IAA) system only allows Excel to be initialised if the SIG level is greater than or equal to the TGT level when Enter is pressed. The smallest TGT signal level that is initially set will be equivalent to 70% (0.700) of the signal expected for the installation’s path length. The TGT level will increase gradually if the current SIG level is larger than the TGT level. The TGT signal level only ever increases. If the current SIG level falls below the TGT level, TGT will remain at its previous highest value. In order to initialise the gas detector the SIG level must be brought back above the TGT level. If the SIG level is less than 50% of the expected level, the bar graphs are not displayed. Instead both SIG and TGT levels are displayed as numbers. 91 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel APPENDIX A - HANDHELD INTERROGATOR Options The approach to mechanical alignment depends on the type of alignment telescope and mounting initially used to set up the Excel gas detector, also see Chapter 3. Bayonet-style Trident-type telescope assembly If this type of alignment telescope was used with a Trident-type Excel gas detector, there is no need to further optimise the alignment using the SHC1 Handheld Interrogator. When the SIG and TGT bar graphs are displayed on the SHC1 screen, SIG will always be greater than TGT and installation can proceed to the next stage by pressing Enter and following step 12. Latch-style telescope assembly If this type of alignment telescope was used with a Trident-type Excel gas detector, there is no need to further optimise the alignment using the SHC1 Handheld Interrogator. If this type of alignment telescope was used with a non-Trident Excel it may be necessary to further optimise the alignment in the following way in order to achieve best performance. (a) After the SIG and TGT bar graphs are displayed on the SHC1 screen as previously described, let the TGT level reach its initial maximum by waiting for approximately 10 seconds. During this time the TGT level will move up towards the current SIG level. (b) Whilst watching the SIG level closely, make a small mechanical adjustment in either the horizontal or vertical alignment and note whether the SIG level goes up or down. (c) If the SIG level goes up, make another small mechanical adjustment in the same direction as before. (d) If the SIG level goes down, change the direction of adjustment. Maximise the SIG level by making small adjustments in only one plane at a time. (e) When the SIG level has been maximised in one plane, make small adjustments in the other plane until SIG has been maximised in this plane. (f) Repeat steps (b) to (e) until the SIG level has been maximised in both planes. At this point, SIG must be bigger than the initial TGT level and any adjustment either side of the current alignment must result in a reduction in signal level. If not, repeat steps (b) to (e) until these requirements have been met. (g) Lock off the alignment by placing a hex (Allen) key in the pair of grub-screws which control adjustment in a particular plane and simultaneously rotating them in opposite directions. (h) Repeat this for the other pair of grub-screws. (i) Press Enter and the signal levels are checked. Provided that the SIG level is greater than the TGT level, the signal check should pass on to the next stage of installation. 92 MAN0530 Issue 11 - 05/11 2104M0506 Searchline Excel APPENDIX A - HANDHELD INTERROGATOR Initialisation This starts the initialisation process.
