GTC-200A

1. Introduction GTC-200A Series has a high performance A/D converter and micro-processor so that it has various functions built-in. GTC-200A Series is centralized, that is, composed of one common alarm unit and several multi-channel control units. Each multi-channel control unit is connected to its sensing part. GTC-200A is encapsulated in DIN type case. There are two product types - Panel mount type and Wall mount type. GTC-200A has FND digital display (PV value) function and 3 colors LED bar graphic display (PV & alarm set value) function, it also has three instant alarm (1 st H/L, 2nd H/L, and 3rd H/L) and trouble alarm.

2. Features GTC-200A Series produces audible (buzzer) and visual (alarm LED and bar graphic LED flashing) warnings in case of instant alarm and trouble alarm. If an alarm occurs, this product can hold a Max. PV value holding. GTC-200A series enables remote control for alarm cancellation. Our product can carry out synchronous control functions because it has an output signal of the alarm (SPDT contact). GTC-200A series offers two outputs; Isolation type RS-485 signal (Option) is provided for a monitoring system from common unit, the other is a measurement output (4-20mA, DC) from channel control unit. Since GTC-200A series is composed of the state of art parts, it has stability and credibility. It can be expanded as large as its maximum (up to 64 channels)

GTD2000-Tx Instruction Manual

1. Overview GTD2000-Tx toxic gas detector was developed in order to prevent accident by detecting gas leaking in industrial fields such as various toxic gases that are generated in plants manufacturing or using toxic gas, gas storage, or in the manufacturing process. GTD2000-Tx toxic gas leak detector is installed in areas of risk of leakage; constantly and continuously detects gas leak; displays the measured value in the liquid crystal display (LCD) installed in the detector; and provides DC4-20mA standard output signal. In addition, the Cable Connection Length of DC4 ~ 20mA standard output signal between sensor element and receiver extends up to 2,500m (When Cable CVVS or CVVSB 1.5sq or equivalent is used). This GTD2000-Tx toxic gas detector should be used at an elevation of less than 1000M.

2. Structure The body of GTD2000-Tx is made of aluminum alloy, and completely explosion-proof (Ex d IIC T6). The product may be installed anywhere risky of combustible gas leak and explosion, displaying the gas leak status in the installation site on the built-in liquid crystal display (LCD) within the sensing unit. The internal structure is composed of a liquid crystal display unit displaying the measurement; a terminal unit sending the measured value (DC4-20mA) to outside; and a PCB Board. A magnet bar is installed outside, so maintenance work is convenient because calibration is possible from outside using this magnet-bar.

Ventis™ MX4 Product Manual

General Usage Oxygen-deficient atmospheres may cause combustible gas readings to be lower than actual concentrations. Oxygen-enriched atmospheres may cause combustible gas readings to be higher than actual concentrations. Sudden changes in atmospheric pressure may cause temporary fluctuations in the oxygen reading. Verify the calibration of the combustible gas sensor after any incident where the combustible gas content has caused the monitor to display an over-range condition. Sensor openings, water barriers, and the pump inlet must be kept clean. Obstruction of the sensor openings or pump inlet and/or contamination of the water barriers may cause readings to be lower than actual gas concentrations. To avoid the potential of liquid being pulled into the sample tubing and pump assembly, it is recommended that Industrial Scientific filter (P/N 17027152) be used on the sample tubing when drawing samples using the aspirated monitor. WARNING: INSERT THE ALKALINE BATTERIES WITH THE CORRECT POSITIVE “+” AND NEGATIVE “-“ ORIENTATION. WARNING: The Ventis MX4 is only approved for use with AAA battery types Energizer EN92 and Duracell MN2400. Do NOT mix battery types. WARNING: The use of leather cases can produce inaccurate readings with diffusion (non-aspirated) gas detection instruments for specific monitoring applications. Leather cases should be used ONLY as carrying cases, and NOT for continuous monitoring, with diffusion instruments configured to measure gases other than O2, CO, CO2, H2S, and combustible gases (LEL/CH4).

Agency-issued Conditions of Use and Warnings Ensure all part-use restrictions (e.g., battery) meet any agency-mandated conditions of use. Ensure all instrument-configurable settings (e.g., always-on setting) meet any agency-mandated conditions of use. When using instrument-compatible Industrial Scientific docking stations, maintain mandated settings through the software (e.g., iNet Control or Accessory Software) or by manually configuring the instrument settings after docking. The Ventis MX4 is CSA certified according to the Canadian Electrical Code for use in Class I, Division 1 and Class I, Zone 1 Hazardous Locations within an ambient temperature range of Tamb: -20°C to +50°C. CSA has assessed only the %LEL combustible gas detection portion of this instrument for performance according to CSA Standard C22.2 No. 152. This is applicable only when the monitor is used in the diffusion mode and has been calibrated to 50% LEL CH4, and when the monitor is used in the aspirated mode with an extended range lithium-ion battery and has been calibrated to 50% LEL CH4. CAUTION: CSA C22.2 No. 152 requires before each day’s usage, sensitivity must be tested on a known concentration of pentane or methane equivalent to 25% or 50% of full scale concentration. Accuracy must be within -0% to +20% of actual concentration. Accuracy may be corrected by referring to the zero/calibration section of the Product Manual. The equipment complies with the standards IEC 60079-29-1 and EN 60079-29-1 for methane, propane, and hexane with the following exception: as for the methane (mine) detector, the battery run time was verified to be seven (7) hours rather than the eight (8) hours recommended by the standards, respectively. MED-certified instruments may be used only when configured and maintained to disallow power-off when the unit is in alarm. The Mine Safety and Health Administration (MSHA) has approved the Ventis MX4 as a Permissible Multi-Gas Monitor with the following warnings: 

MSHA approved for use with either the P/N 17134453-X2, 3.7 volt, lithium-ion battery or P/N 17148313-2, 3.7 volt, lithium-ion extended battery pack assembly only. The battery pack is not user-replaceable. The monitor battery and the lithium battery on the main PCB are technician replaceable only.

Ventis™ MX4 Product Manual

  

The monitor is to be calibrated according to the procedures in the instruction manual only. The aspirated version of the Ventis MX4 is only approved for use with the extended battery pack. The monitor must display methane in the percent-by-volume mode (0-5%) for compliance determinations required by 30 CFR Part 75, subpart D.

SANS 1515-certified units may be used only as follows:  Diffusion applications  Configured and maintained to disallow power-off when the unit is in alarm  The Methane alarms are set as follows: low alarm = 1%vol and high alarm =1.4%vol  With approved Lithium-ion battery packs (see Ventis MX4 Accessories and Parts in this manual).

Recommended Practices Industrial Scientific Corporation recommends the monitor be fully charged (when equipped with a rechargeable battery pack), configured, and calibrated before first time use. If the lithium-ion battery is deeply discharged, it can take up to an hour for the instrument display to indicate that the battery is charging. Monitors used infrequently should be fully charged every four months. No part of the unit should be covered by any garment, part of a garment, or other item that would restrict the flow of air to the sensors or impair the operator's access to the audible, visual, or vibration alarms. Industrial Scientific Corporation recommends a full monitor calibration be performed monthly (at a minimum), using a certified concentration(s) of Industrial Scientific calibration gas(es) to help ensure monitor accuracy. Industrial Scientific Corporation recommends the monitor be zeroed and bump tested before each use with a certified concentration(s) of Industrial Scientific calibration gas(es). Battery contacts are exposed on battery packs when they are removed from the monitor. Do not touch the battery contacts and do not stack battery packs on top of one another. When reassembling the instrument or installing a battery pack, maintain ingress protection by tightening each fastener to its stated torque value (see the “Ventis MX4 Monitor three-Dimensional Diagram” and its key in this manual). Contact your service representative immediately if you suspect that the Ventis MX4 is working abnormally. Industrial Scientific recommends the “2 & 2 Sampling Rule” when sampling with a motorized pump and tubing, one should allow for 2 minutes plus 2 seconds per foot of tubing used, prior to noting the monitor readings. This allows time for the gas to reach the instrument and for the sensors to adequately react to any gases present. Industrial Scientific recommends that clear urethane tubing, part number 17065970, be used with the pumped versions of the Ventis MX4 when sampling for the following gases: Nitrogen Dioxide (NO2) and Sulfur Dioxide (SO2).

Ventis™ MX4 Product Manual

ALARMS NOTICE  All monitor alarms and warnings should be taken seriously and responded to as stated in company safety standards.  Once initiated, an alarm will remain on while the alarm condition is present. For gas-related alarms, once the detected gas concentration changes, the alarm indicators will change to reflect any new condition such as low-alarm gas, high-alarm gas, over-range gas, or no gas alarm.  When the latch alarm feature is enabled and the monitor goes into alarm, it will remain in alarm until the alarm condition no longer exists and the monitor user presses the ENTER button for one second. This applies only to gas-related alarms. It is practical for the monitor user to be aware of the possible alarms prior to monitor set-up and use. The Ventis MX4 has four alarm and warning levels. A “system level” alarm generates the highest frequency tone and highest level visual and vibration signals. It is used to indicate such events as a pump or sensor failure. The “high” or “low” level audio alarms, in combination with visual and vibration indicators, turn on when gas concentration readings are overrange, high, or low. The lowest level indicator is a warning with beep patterns to indicate service needs (e.g., low battery or calibration due). The beep is also used as a confidence indicator when enabled. Alarm types and their alarm generating conditions are described below.

Display

Description An over-range condition occurs when the gas concentration value sensed is above the sensor’s measuring range. After any over-range alarm, the monitor should be calibrated.

Over-range Alarm Screen The “Or” message indicates which sensor(s) is reading an overrange condition(s). All other sensors show their current gas concentration readings on a numeric display (left) or gas names on a text display (right). The high level alarms turn on and the alarm icon displays.

NOTES: The O2 and toxic sensor values normally reset when the gas sensed reaches an acceptable range.

If the LEL reads over-range, the alarm latches and the LEL sensor is automatically turned off. Press the enter button to turn on the LEL sensor. This will turn off the alarm indicators. After a warm-up period of approximately 30 seconds, an LEL reading will display. If the new reading is an over-range or other alarm condition, the alarm indicators will turn on.

A negative over-range condition occurs when the gas concentration value sensed is less than the sensor’s measuring range. After any negative over-range alarm, the monitor should be calibrated. Negative Over-range Alarm Screen The “-Or” message indicates which sensor is reading a negative over-range condition. All other sensors display their current gas concentration readings*.

►Monitor Use and Service Proper monitor use and service includes everything from bump testing and calibration to keeping the monitor clean, proper air sampling, and the replacement of parts and components. Beginning with calibration and bump testing, the following sections provide information and instruction on all use and service tasks.

ZERO, CALIBRATION, AND BUMP TESTING Gas detection instruments are potentially life-saving devices. When completed regularly, the procedures defined below help to maintain proper instrument functionality and enhance operator safety. Procedures Configuration. The configuration process allows qualified personnel to review and adjust a unit's settings. Bump Test (or "functional test"). Bump testing checks for sensor and alarm functionality. The installed sensors are briefly exposed to expected concentrations of calibration gases that are greater than the sensors’ low alarm set points. When one or more sensors “pass” the test, they are “functional” and the unit will alarm. Each sensor’s “pass” or “fail” result is indicated on the unit’s display. Note: a bump test does not measure for sensor accuracy (see “Calibration”).

Zero. Zeroing sets each installed sensor to recognize the ambient air as clean air. If the ambient air is not truly clean air, any gasses that are present and relevant to the installed sensor types will be measured and displayed as zero. Readings will be inaccurate until the unit is correctly zeroed in truly fresh air or with a zero air cylinder. Calibration. All sensors gradually degrade over time. This diminishes a sensor's ability to measure gas concentrations accurately; however, regular calibrations adjust the instrument to compensate for this decline in sensitivity. During calibration, the installed sensors are exposed to expected concentrations of calibration gases and, when needed, the instrument will self-adjust to ensure the accurate measurement and display of gas concentration values. Note: when a sensor has degraded beyond an acceptable level, no further adjustment is possible and the sensor will no longer pass calibration.

Peak Readings. The instrument stores the highest detected gas readings, the "peak readings" or "peaks". Bump testing and calibration will often register new peak readings. Therefore, the clearing of the peak readings should follow each calibration. The instrument operator may also wish to clear the peak readings after a bump test, before a change in location, or after an alarm is addressed and cleared.

© 2014 Industrial Scientific Corporation

24

Ventis™ MX4 Product Manual Note: The peak readings and the data log readings are stored independently of one another; therefore, clearing the peak reading does not affect the data log. Powering the instrument off or changing its battery does not affect the peak reading. These checks and balances help promote operator safety, and serve to contain the peak readings in a "black-box" manner. In the event of a gas-related incident, this black-box record can be useful to the safety team or a prospective investigator.

Recommendations Industrial Scientific Corporation (ISC) minimum frequency recommendations for each procedure are summarized in the table below. These recommendations are based on field data, safe work procedures, industry best practices, and regulatory standards to help ensure worker safety. Industrial Scientific is not responsible for setting safety practices and policies. These policies may be affected by the directives and recommendations of regulatory groups, environmental conditions, operating conditions, instrument use patterns and exposure to gas, and other factors. Procedure

ISC Recommended minimum frequency

regular calibrations, ISC also recommends a calibration be performed immediately following each of these incidences: the unit falls, is dropped, or experiences another significant impact; is exposed to water; fails a bump test; or has been repeatedly exposed to an over-range (positive or negative) gas concentration. A calibration is also recommended after the installation of a new (or replacement) sensor. bIf conditions do not permit daily testing, bump tests may be done less frequently based on company safety policy. Note: The use of calibration gases not provided by ISC may void product warranties and limit potential liability claims.

General information The zero, calibration, and bump testing tasks are in-field enabled or in-field disabled in the configuration process. This permits or denies access to these functions from the gas monitoring mode. When any of these options is enabled, it is accessible to all monitor users. In gas monitoring mode, a series of presses on the ON/OFF/MODE button gives the user access to the following screens and processes in the order shown.       

Gas Monitoring Screen Days Since Calibration Zero Initiate (if in-field enabled) o Calibration Apply Gas Screen (if in-field enabled) Bump Test Initiate (if in-field enabled) Peak Readings TWA Readings STEL Readings

The monitor is capable of performing two types of calibration, and this option is set in configuration mode. The calibration type selected also determines the monitor’s bump test type. With a “quick” calibration, the monitor is set to calibrate and bump test all installed sensors simultaneously. With a “standard” calibration setting, these tasks are completed independently for each installed sensor in the order shown below. 1. Oxygen sensor* 2. Toxic sensor 1 3. LEL sensor 4. Toxic sensor 2 *If set to the default value of 20.9% or 21%, the Oxygen sensor calibrates during the zero process and toxic 1 is the first to calibrate in the calibration process.

RECOMMENDED PRACTICES FOR IN-FIELD AIR SAMPLING Diffusion monitor When worn, the diffusion monitor should be fastened securely and attached to ensure the sensor portals are exposed to the air. The monitor should be in full view. No part of the monitor should be covered by any garment or part of a garment. Aspirated monitor Before using an aspirated monitor, force a pump fault to ensure the pump and air-sample accessories (sample tubing, probe, or sample tubing and probe) are working as intended: 1 Power on the monitor. 2 Attach the air-sample accessory(ies) to the pump inlet. 3 Using a finger, cover the opening at the other end of the air-sample tubing (or probe) to block the flow of air. This should result in a pump fault alarm. 4 After a pump fault occurs, remove the finger from the tubing (or probe). If the unit resumes normal operation, the pump and air-sampling accessories are working as intended. Note: If no pump fault occurs or if the unit stays in pump fault, check for debris at these locations: the pump nipple, inside the inlet barrel, at the water barrier, and inside the pump cradle; attempt to clear any blockage. Check the airsample accessories, too, for debris and for possible crack or leaks. The Ventis MX4 aspirated monitor is rated to sustain a continuous sample draw for up to 100 feet (30.48 m) with 0.125 inch (0.3175 cm) inside diameter sample tubing. In confined space, an air sample should be taken in four foot (1.2192 m) intervals. With each sample, the minimum time required to successfully draw air and read the gas concentrations should include two minutes plus two seconds for every 12 inches (30.48 cm) of tubing.

CLEANING    

NEVER use solvents or cleaning solutions of any type. When necessary, wipe the outside of the Ventis MX4 with a soft, clean cloth. Make sure the sensor diffusion membrane, inside and out, is free of debris; wipe gently with a cloth or brush that is soft, clean, and dry. Make sure the aspirated monitor’s inlet is free of debris.

NOTE: The table above provides the LEL for select combustible gases*. It also provides correlation factors that help the safety technician and instrument operator determine the actual percentage LEL when the sample gas differs from the gas that was used to calibrate the unit. For example, if the unit reads 10% LEL in a pentane atmosphere, and was calibrated to methane, the actual percentage LEL is determined as follows: 1. Locate the table cell where the sample gas (pentane) intersects with the calibration gas (methane). 2. Multiply the cell's value (2.02) by the unit's LEL reading (10%) to calculate the actual concentration of 20.2% LEL. * The combustible gas list is not a comprehensive list of all combustible gases that can be detected by the Ventis MX4. For additional information about combustible gas detection and the Ventis MX4, contact the ISC Technical Service department.

Failure to perform certain procedures or note certain conditions may impair the performance of this product. For maximum safety and optimal performance, please read and follow the procedures and conditions listed below. Table 1.2 Warnings and cautionary statements For maximum safety and optimal performance, read and understand the manual before operating or servicing the unit. Failure to perform certain procedures or note certain conditions may impair the performance of this product. For safety reasons, this equipment must be operated and serviced by qualified personnel only. Substitution of components may impair intrinsic safety and may cause an unsafe condition. Do not replace battery in hazardous locations. Only certified for use with one Tadiran TL-5955 battery cell. Obstruction of sensor openings – due to dust, dirt, water, or another cause – can inhibit the unit’s ability to measure gas concentrations accurately. When this occurs, readings may appear lower than the actual gas concentration. Keep sensor openings clean, dry, and properly exposed to the ambient air. Obstructed, contaminated, or damaged sensor water barriers (or their gaskets) can inhibit the unit’s ability to measure gas concentrations accurately. When this occurs, readings may appear lower than the actual gas concentration. Replace the sensor water barriers and gaskets as needed (see “Service” for instructions). Service the unit, use its communications port, and change its battery cell only in nonhazardous locations. Not for use in oxygen-enriched atmospheres. Contact your service representative immediately if you suspect that the unit is working abnormally.

Product Overview The Tango TX1 is a portable, long-life, single-gas monitor (instrument) for personal protection. It is a diffusion instrument for use in detecting and measuring gas present in open space. Based on the customer’s order, two redundant sensors – sensors of the same type – are factory installed. Four sensor types are available (see Table 1.3).

Note: See Table 1.5 for sensor specifications.

When two working sensors are installed, they measure gas simultaneously and independently and the Tango TX1 operates on DualSenseTM Technology from ISC. If only one sensor is installed or only one installed sensor is operational, the unit operates as a single-sensor or non-DualSense unit. If two working sensors are installed, the data log contains a data set for each sensor, plus a third data set. This third data set – labeled "VIRTUAL" or "3" – is created by the DualSense technology. Each VIRTUAL data point is an algorithm-calculated value that is based on sensor 1 and sensor 2 data. The VIRTUAL data are saved to and downloaded from the data log just as data are for the installed sensors. VIRTUAL gas readings are displayed to the instrument operator. The Tango TX1 multiplane sensor ports each sample air from three directions; this promotes continuous operation if one or two planes become obstructed. Tango TX1 measures gas at two second intervals, and continuously logs data every ten seconds. The data log can store approximately three months of data for a unit that is on 24 hours a day and has two installed, operational sensors. As the newest data are logged to memory, the oldest data are overwritten. The data log's date- and timestamped event log records and stores event data for 60 alarm events and 30 error events. It also stores the data for up to 250 manual calibrations and bump tests. The data log is downloaded when the unit is docked in a compatible docking station. The instrument has two modes: configuration and operation. When in configuration mode, a unit's settings can be manually edited. Entry to configuration mode can be password protected. When the instrument is on and is not in configuration mode, it is said to be in operation mode. The instrument features an always-on option that can be enabled or disabled from configuration mode. The Tango TX1 has a multisensory (audible, visual, and vibration), multilevel warning and alarm system. Warnings indicate a service need (calibration due) or an operating condition (confidence indicator). Alarms indicate potentially hazardous gas concentrations or system faults. Alarms can be set to latch. The instrument also features a country-oforigin option that automatically sets the values for the low-gas and high-gas alarm set points for each of five different countries or regions; each alarm set point value can also be manually edited. An optional AlarmAmpTM is available; when used, the audible alarm volume is increased by approximately 10 decibels (dB). The user interface consists of two buttons and an LCD (liquid crystal display). The buttons are used to power on and power off the instrument, navigate the operation and configuration loops, perform tasks, and access information. The unit can be set to display select information in English or French. The unit's suspender clip is intended for attachment to a garment; it is not intended for attachment to a belt or hard hat. An optional belt clip is available from ISC (see "Service"). The Tango TX1 is iNet ready and compatible with the Tango TX1 iNet DS (docking station).

2 Recommended Practices Introduction Procedures First Use Wearing the Instrument

Introduction Gas detection instruments are potentially life-saving devices. When completed regularly, the procedures defined below help to maintain proper instrument functionality and enhance operator safety.

Procedures Configuration. The configuration process allows qualified personnel to review and adjust a unit's settings. Self-test. The self-test verifies the functionality of the instrument’s memory operations, battery, and each alarm indicator (audible, visual, and vibration). Note: a self-test does not verify sensor functionality (see “Bump Test”) or instrument accuracy (see “Calibration”).

Bump Test (or "functional test"). Bump testing checks for sensor and alarm functionality. The installed sensors are briefly exposed to an expected concentration of calibration gas that is greater than the sensors’ low alarm set point. When one or more sensors “pass” the test, they are “functional” and the unit will alarm. Each sensor’s “pass” or “fail” result is indicated on the unit’s display. Note: a bump test does not measure for accuracy (see “Calibration”).

Zero. Zeroing sets each installed sensor to recognize the ambient air as clean air. If the ambient air is not truly clean air, any gases that are present and relevant to the installed sensor types will be measured and displayed as zero. Readings will be inaccurate until the unit is correctly zeroed in truly fresh air or with a zero air cylinder. Calibration. All sensors gradually degrade over time. This diminishes a sensor's ability to measure gas concentrations accurately; however, regular calibrations adjust the instrument to compensate for this decline in sensitivity. During calibration, the installed sensors are exposed to an expected concentration of calibration gas and, when needed, the instrument will self-adjust to ensure the accurate measurement and display of gas concentration values. Note: when a sensor has degraded beyond an acceptable level, no further adjustment is possible and the sensor will no longer pass calibration.

Recommended Practices

Peak Readings. The instrument stores the highest detected gas readings, the "peak readings" or "peaks". Bump testing and calibration will often register new peak readings. Therefore, the clearing of the peak readings should follow each calibration. The instrument operator may also wish to clear the peak readings after a bump test, before a change in location, or after an alarm is addressed and cleared. Note: The peak readings and the data log readings are stored independently of one another; therefore, clearing the peak reading does not affect the data log. Powering the instrument off or changing its battery does not affect the peak reading. These checks and balances help promote operator safety, and serve to contain the peak readings in a "black-box" manner. In the event of a gas-related incident, this black-box record can be useful to the safety team or a prospective investigator.

Recommendations Industrial Scientific Corporation (ISC) minimum frequency recommendations for each procedure are summarized in the table below. These recommendations are based on field data, safe work procedures, industry best practices, and regulatory standards to help ensure worker safety. Industrial Scientific is not responsible for setting safety practices and policies. ISC recommendations include a daily bump test for any ISC instrument that is not operating on DualSense technology. This includes the Tango TX1 when it is operating with only one working sensor. When two redundant, working sensors are installed in the Tango TX1, the instrument is operating on DualSense and the probability of sensor failure – compared with a single-sensor instrument – is diminished regardless of bump test frequency (see Figure 1). The frequency of bump testing for DualSense instruments, between monthly calibrations, is best determined by a company's safety policies. These policies may be affected by the directives and recommendations of regulatory groups, environmental conditions, operating conditions, instrument use patterns and exposure to gas, and other factors. Table 2.1 ISC recommended practices Procedure

Recommended minimum frequency

regular calibrations, ISC also recommends a calibration be performed immediately following each of these incidences: the unit falls, is dropped, or experiences another significant impact; is exposed to water; fails a bump test; or has been repeatedly exposed to an over-range (positive or negative) gas concentration. A calibration is also recommended after the installation of a new (or replacement) sensor. bIf conditions do not permit daily bump testing, the procedure may be done less frequently based on company safety policy. cThe Tango TX1 self-test is performed automatically during the start-up process. It can be user-initiated from operation mode. Note: The use of calibration gases not provided by ISC may void product warranties and limit potential liability claims.

Start-up and Shutdown The start-up and shutdown sequences are outlined below and feature reproductions of the display screens the instrument operator will see during these processes (see Table 3.4). Instructions accompany any display screen where the instrument operator must press a button to proceed. The instrument operator may be prompted to complete the time- and date-setting tasks during start-up. This may happen after a battery has been removed or changed. If prompted by the unit to do so, it is essential – for data log accuracy – that the time- and date-setting tasks be completed. The data log plays an important role in preserving operator safety and in the prospective investigation of an incident. The instrument operator may be prompted to enter a security code during shutdown. This will occur if the unit is configured for "always-on" and is security-code protected.

One press saves the displayed value; a second press activates the next configuration-mode screen.

Country-of-origin setting

This display screen features the country-of-origin icon and the current setting. This feature sets automatically the low- and high-gas alarm set points. The technician must choose one of these options: “DEF” = USA and default value “CAn” = Canada “EUr” = Europe “CR” = Czech Republic “AUS” = Australia The unit's settings are immediately updated to reflect that country's (or Europe's) low- and high-gas alarm set points for the installed sensor-type. When the country-of-origin selection does not contain a value for an alarm set point, the default value (DEF) is automatically substituted. The first press activates the value. Continued presses increment the value; hold to speed the increment pace. One press saves the displayed value and activates the next configuration-mode screen. Notes: Each alarm setting can be edited individually, in configuration mode, at that alarm's set point screen. Because low- and high-gas alarm set points can be edited both individually and through the country-of-origin option, it is important to understand override behavior. Example. The H2S low-gas alarm set point was edited – at its set point screen – to a value of 9 ppm. Afterwards, a country-of-origin selection was made where the H2S low-gas alarm set point value is 10 ppm. The last-entered setting overrides the first. Therefore, in this example, the value of the H2S low gas alarm set point is 10 ppm. Another aspect to alarm settings applies to replacement or new sensors. For example:  If the installed H2S sensor(s) is replaced with other H2S sensor(s), the last-entered low-gas alarm set point (a value of 10 ppm in the above example) will be applied to the newly installed sensor(s).  If the installed H2S sensors are replaced with a different sensor type (e.g., CO), the alarm settings will be read from the newly installed sensor(s).

Instrument Preparation and Use



Span reserve value If at least one sensor passes the calibration, the gas-monitoring screen will be automatically activated. Note: The span reserve value divided by the calibration gas concentration yields the span reserve percentage. A span reserve percentage of greater than 70% indicates a “good” sensor; 50%-70% indicates “marginal” sensitivity. When the span reserve percentage is less than 50%, the sensor will not pass calibration.

To stop the flow of gas, turn the regulator knob in a clockwise direction and tighten.

The data reflect the percentage response of the sensor type when exposed to a known concentration of a target gas. For example, when the carbon monoxide sensor is exposed to carbon monoxide in the air sample, the gas concentration reading accurately reflects the actual concentration of carbon monoxide, so the sensor's response is said to be 100%. When an air sample contains hydrogen, it triggers a carbon monoxide reading. The carbon monoxide sensor's response to hydrogen is approximately 60% meaning that exposure to 100 ppm hydrogen will produce a reading of approximately 60 ppm carbon monoxide.
