Safety and Precautionary Measures to be Adopted

WARNING

Carefully review the following safety limitations and precautions before placing this device in service. Do not alter or modify the device.

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

WARNING

All device readings and information must be interpreted by someone trained and qualified in interpreting device readings in relation to the specific environment, industrial practice and exposure limitations.

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

Before each day’s use, check the function of the device (® Function Tests). MSA recommends carrying out a routine inspection prior to each day’s use.

If your device contains Bluetooth functionality, Bluetooth operation is dependent upon signal availability of the wireless service(s) necessary to maintain the communication link. Loss of wireless signal will prevent communication of alarms and other information to linked devices. Take appropriate precautions in the event a loss of wireless signal occurs.

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 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.

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.

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.

Recheck calibration if device is subjected to physical shock, or is completely submerged underwater.

Combustible, oxygen and toxic gas performance approvals are valid to a maximum ambient air velocity of 6m/sec. An air velocity higher then 6m/sec may cause erroneous gas readings.

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.

Allow sufficient time for device to display accurate reading. Response times vary based on the type of sensor being utilized.

Use only battery chargers made available by MSA for use with this device; other chargers may damage the battery pack and the device. Dispose of in accordance with local health and safety regulations.

Use of the MSA GALAXY® GX2 Automated Test System is an alternate approved method for charging ALTAIR 4XR devices.

As the battery pack ages, there will be a reduction in usable device runtime.

Risk of explosion: Do not recharge device in hazardous area.

A number of environmental factors may affect the sensor readings, including changes in pressure, humidity and temperature. Pressure and humidity changes also affect the amount of oxygen actually present in the atmosphere. Reference Technical Data for acceptable ambient conditions.

The device contains electrostatically sensitive components. Do not open or repair the device without using appropriate electrostatic discharge (ESD) protection. The warranty does not cover damage caused by electrostatic discharges.

Follow all relevant national regulations applicable in the country of use.

The warranties made by MSA The Safety Company with respect to the product are voided if the product is not used and maintained in accordance with the instructions in this manual. Please protect yourself and others by following them. We encourage our customers to write or call regarding this equipment prior to use or for any additional information relative to use or service.

•

In the event of combustible sensor overrange, the device will enter a Lock Alarm state, which must be reset in a fresh air environment. To reset this alarm, cycle power off and on, in fresh air. Keep the device in the fresh air environment until LEL or CH4 readings have stabilized and then follow the Fresh Air Setup and Zero Calibration instructions contained in this manual.
