ALTAIR 4XR

US

2 Safety Regulations
Bump test frequency is often stipulated by national or corporate regulations; however, bump testing before each day’s use is generally the accepted best safety practice and is therefore MSA’s recommendation. The device must pass the bump test. If it fails the test, perform a calibration before using the device.
Perform a bump test (see 4.8 Bump Test) more frequently if the device is subjected to physical shock or high levels of contaminants. Also, perform a bump test more frequently if the tested atmosphere contains the following materials, which may desensitize the combustible gas sensor and reduce its readings:
· Organic silicones · Silicates · Lead-containing compounds · Hydrogen sulphide exposures over 200 ppm or exposures over 50 ppm for one minute.
Check minimum concentration of a combustible gas
The minimum concentration of a combustible gas in air that can ignite is defined as the Lower Explosive Limit (LEL). A combustible gas reading of “XXX” indicates the atmosphere is above 100 % LEL or 5.00 % vol CH4, and an explosion hazard exists. Move away from hazardous area immediately.
Observe atmosphere
Do not use the device to test for combustible or toxic gases in the following atmospheres as this may result in erroneous readings:
· Oxygen-deficient or oxygen-rich atmospheres · Reducing atmospheres · Furnace stacks · Inert environments · Atmospheres containing combustible airborne mists/dusts.
Use the device only to detect gases/vapors for which a sensor is installed.
The device is suitable and certified for the measurement of the oxygen concentration in gas mixtures for inertization according to EN 50104 but without alarm function.
Make sure >10% oxygen is present for accurate combustible readings with the catalytic sensor.
Not to be used for gases having a flash point in excess of 38 °C (100 °F)
Do not use the device to test for combustible gases in atmospheres containing vapors from liquids with a high flash point (above 38 °C, 100 °F), as this may result in erroneously low readings.
Physical shock
Recheck calibration if device is subjected to physical shock.
Sensor maintenance
Do not block sensor openings as this may cause inaccurate readings. Do not press on the face of the sensors, as this may damage them and cause erroneous readings. Do not use compressed air to clean the sensor holes, as the pressure may damage the sensors.
Observe Proper Time for Display Stabilizing
Allow sufficient time for device to display accurate reading. Response times vary based on the type of sensor being utilized.

3 Description
· LOW Alarm · STEL Alarm · TWA Alarm
If the gas concentration reaches or exceeds the alarm set point, the device:
· backlight turns on · triggers a vibrating alarm · displays and flashes the Alarm symbol and either the Minimum icon (LOW alarm) or the Maximum (PEAK) icon
(HIGH alarm) · enters an alarm state.
When a gas reading exceeds the full scale range of the sensor, the device displays “+ + +” in place of the actual reading.
When a gas reading falls below a defined under-range threshold, the device displays ” – – -” in place of the actual reading.
3.10 Monitoring Oxygen Concentration The device monitors the oxygen concentration in ambient air. The alarm set points can be set to activate on two different conditions:
· Enriched – oxygen concentration > 20.8% or · Deficient – oxygen concentration < 19.5%.
While the device can detect up to 30% oxygen in the ambient air, it is approved for use only up to 21% oxygen-content.
WARNING! If an alarm activates while using the device, leave the area immediately.Remaining in the area under such circumstances can cause serious personal injury or death.
When the alarm set point is reached for either of the above conditions:
· an alarm sounds · alarm LEDs flash · a vibrating alarm triggers · device displays and flashes the Alarm icon and either the Minimum icon (Enriched alarm) or the Maximum icon
(Deficient alarm) ( 3.3 On-Screen Indicators) along with the corresponding oxygen concentration.
The LOW alarm (oxygen deficient) is latching and will not automatically reset when the O2 concentration rises above the LOW set point. To reset the alarm press the p button. If the alarm condition still exists, the p button only silences the alarm for five seconds.
False oxygen alarms can occur due to changes in barometric pressure (altitude) or extreme changes in ambient temperature.
It is recommended that an oxygen calibration be performed at the temperature and pressure of use. Be sure that the device is in known fresh air before performing a calibration.
When a gas reading exceeds the full scale range of the sensor, the device displays “+ + +” in place of the actual reading.
When a gas reading falls below a defined under-range threshold, the device displays ” – – -” in place of the actual reading.

3.11 Monitoring Combustible Gases The device can monitor these concentrations in ambient air:
· Methane · Combustible gases The device displays the combustible gas concentration in % LEL or % CH4 on the Measuring page until another page is selected or the device is turned off.
WARNING! If an alarm activates while using the device, leave the area immediately.Remaining in the area under such circumstances can cause serious personal injury or death.
The device has two alarm set points: · HIGH Alarm · LOW Alarm
If the gas concentration reaches or exceeds the alarm set point, the device: · backlight turns on · a vibrating alarm triggers · displays and flashes the Alarm symbol and either the Minimum icon (LOW alarm) or the Maximum (PEAK) icon (HIGH alarm) · enters an alarm state.
When a gas reading reaches 100% LEL or 5.00% CH4, the device enters a Lock Alarm state: the combustible sensor shuts down and displays “XXX” in place of the actual reading. This state can only be reset by turning the device off and on in a fresh air environment. When a gas reading falls below a defined under- range threshold, the device displays ” – – -” in place of the actual reading.

WARNING! · A combustible gas reading of “100” or “5” indicates the atmosphere is above 100% LEL or 5.00% vol CH4
respectively, and an explosion hazard exists. Move away from contaminated area immediately.
· In such cases, the device enters a Lock Alarm state. Failure to follow this warning can result in serious personal injury or death.

Check your national standard values for 100 % LEL (EN60079-20-1).

4 Operation
Device operation is dialog driven from the display with the aid of the three Function buttons (see Figure 1 Device overview).
4.1 Environmental Factors A number of environmental factors may affect the gas sensor readings, including changes in pressure, humidity and temperature. Pressure and humidity changes affect the amount of oxygen actually present in the atmosphere.
Pressure Changes If pressure changes rapidly (e.g., stepping through airlock), the oxygen sensor reading may temporarily shift and possibly cause the device to go into alarm. While the percentage of oxygen may remain at or near 20.8 Vol %, the total amount of

US

ALTAIR 4XR

4 Operation

oxygen present in the atmosphere available for respiration may become a hazard if the overall pressure is reduced by a significant degree.
Humidity Changes
If humidity changes by any significant degree (e.g., going from a dry, air conditioned environment to outdoor, moisture laden air), oxygen readings can be reduced by up to 0.5 %, due to water vapor in the air displacing oxygen.
The oxygen sensor has a special filter to reduce the effects of humidity changes on oxygen readings. This effect will not be noticed immediately, but slowly impacts oxygen readings over several hours.
Temperature Changes
The sensors have built-in temperature compensation. However, if temperature shifts dramatically, the sensor reading may shift. Zero the device at the work site temperature for the least effect.

WARNING! Perform a Bump Test before each day’s use to verify proper device operation. Failure to perform this test can result in serious personal injury or death.

Bump test frequency is often stipulated by national or corporate regulations; however, bump testing before each day’s use is generally the accepted best safety practice and is therefore MSA’s recommendation.

This test quickly confirms that the gas sensors are functioning. Perform a full calibration periodically to ensure accuracy and immediately if the device fails the Bump Test. The Bump Test can be performed using the procedure below or automatically using the GALAXY GX2 Test Stand.
CSA requires (per 22.2 NO. 152) that combustible sensor sensitivity be tested before each day’s use on a known concentration of methane equivalent to 25 to 50 % of full scale concentration. ACCURACY MUST BE WITHIN 0 to +20 % OF ACTUAL. Correct accuracy by performing the calibration procedure described in 4.10 Calibration.

5 Maintenance
1. Close the valve on the regulator. 2. Remove the calibration cap.
The calibration procedure adjusts the span value for any sensor that passes the ca-libration test; sensors that fail calibration are left unchanged. Since residual gas may be present, the device may briefly go into an exposure alarm after the ca-libration sequence is completed.
Autocalibration Failure
If the span calibration is unsuccessful:
· If the device cannot calibrate one or more sensor(s), it goes to the SPAN ERR page and remains in alarm until the p button is pressed.
· A sensor life indicator is displayed (Alarm symbol and symbol) to show the sensor has reached its end of life and should be replaced.
This occurs if the span calibration is unsuccessful twice.
· The device will remain in alarm state until the p button is pressed. · The Alarm symbol and symbol will remain on the display until a successful calibration or sensor in question is
replaced.
A span calibration can fail for many reasons besides sensor at the end of his life. If a span calibration failure occurs, items such as remaining gas in the calibration cylinder, gas expiration date, security of the calibration cap, etc. should be verified and calibration should be repeated prior to replacing the sensor.
4.11 Time of Day Testing
This feature permits the device to be automatically calibrated on a user- defined interval. The most common use of this feature allows the user to configure the ALTAIR 4XRand the GALAXY GX2 System to automatically calibrate a device prior to the start of work-shift.

suppliers. Failure to follow this warning can result in serious personal injury or death.

To add a sensor to an device that is not already equipped with a full array of sensors, remove the sensor plug from in front of the formerly unused sensor housing.

While device case is open, do not touch any internal components with metallic/conductive objects or tools. Damage to the device can occur.

1. Verify that the device is turned off. 2. Remove the four case screws, and remove the case front while carefully noting the orientation of the sensor gasket. 3. Gently lift out and properly discard the sensor to be replaced.
a. Using fingers only, gently remove the toxic, combustible, or oxygen sensor by gently rocking it while pulling it straight from its socket.
4. Carefully align the new sensor contact pins with the sockets on the printed circuit board and pressing it firmly in place. a. Ensure tab on sensor aligns with groove at top of holder. b. Insert the toxic sensor by placing it in the left-hand position of the sensor holder. c. Insert the O2 sensor by placing it in the right-hand position of the sensor holder. d. Insert the combustible sensor by placing it in the middle position of the sensor holder. e. If any sensor is not to be installed, ensure that a sensor plug is installed properly in its place.
5. Reinstall the case front. 6. Reinstall the screws.
a. Tighten each screw with a torque value of 6.00 in-lbs (+/- 0.25 in-lbs) or 0.678 Nm (+/- 0.028 Nm) to maintain the device’s IP 68 rating.
7. Turn on the device.

If the sensor replaced is the same as the previous sensor: If the sensor replaced is not the same as the previous sensor or this sensor channel was deactivated:

· The device starts up normally.
· The device automatically senses that a new sensor is installed and displays the “SENSOR DSCVRY” screen.

· The device automatically senses the difference and displays “SENSOR CHANGE”.
· “ACCEPT?” appears on the display.
Accept the change with q button or reject with p button.

Go into the sensor setup and turn on the appropriate sensor ( 4.4.1 Sensor Setup).

8. Calibrate the device after the sensors have stabilized.

WARNING!
Calibration is required after a sensor is installed; otherwise, the device will not perform as expected and persons relying on this product for their safety could sustain serious personal injury or death.

Allow sensors to stabilize at room temperature for at least 30 minutes before calibration ( 4.10 Calibration).

5.3 Cleaning
· Routine Cleaning: Clean the exterior of the device regularly using only a damp cloth. Do not use clea-ning agents, as many contain silicone, which will damage the combustible sensor.
· Dust and Dirt Exposure: Use a dry, soft bristled brush to remove any dust or dirt that has accumulated on the apparatus, especially at the sensor openings. If there is a buildup of dust or dirt particles remaining in the sensor area after brushing, use a vacuum to remove remaining particles, but maintain at least a 1/2 inch (1.3 cm) distance from the gas detector.
· Water Exposure: If the apparatus is exposed to water, turn the device sensor side down and gently shake water off the sensor area. Any remaining water can be removed with a clean dry cloth.
5.4 Storage
When not in use, store the device in a safe, dry place between 18 °C (64 °F) and 30 °C (86 °F). After storage, always recheck device calibration before use.
5.5 Scope of Delivery
Pack the device in its original shipping container with suitable padding. If the original container is unavailable, an equivalent container may be substituted.

NOTE: Gas in the table above indicated with a will have significantly longer response times, especially at lower concentration levels.
Response notes
1. Some compounds may reduce the sensitivity of the comb
ustible gas sensor by poisoning or inhibiting the catalytic action or by polymerizing on the catalytic surface.
2. Multiply the displayed % LEL value by the conversion factor above to get the true % LEL. 3. These conversion factors should be used only if the combustible gas is known. 4. All factors are based on the IEC 100 % LEL levels
a. i.e. Methane 100% LEL = 4.4 Vol %, b. Pentane 100% LEL = 1.1 Vol % c. Propane 100% LEL = 1.7 Vol % 5. These conversion factors are typical. Individual units may vary by ±25 % from these values. 6. The results are intended for guidance only. For the most accurate measurements, a device should be calibrated using the gas under investigation. 7. The conversion factors for the standard EX and the specialized EX-H and EX-M sensor are the same except for EXH and Nonane and o-Xylene. The conversion factors for these two vapors are therefore especially mentioned in the table.
Oxygen
The oxygen sensor has built-in temperature compensation. However, if temperature shifts dramatically, the oxygen sensor reading may shift. Zero the device at a temperature within 30 °C (86 °F) of the work place temperature for the least effect.
