The device vibrates when any alarm condition is active. This can be turned OFF through the SETUP- ALARM OPTIONS menu ( 4.5 Device Setup).

Horn

The device is equipped with an audible alarm.

The horn can be turned OFF through the SETUP- ALARM OPTIONS menu (4.5 Device Setup).

InstantAlertTM Alarm

The InstantAlert exclusive feature allows the user to manually activate an audible alarm to alert those nearby to potentially dangerous situations. Holding the q button for approximately 5 seconds while in Normal Measure Mode activates the
InstantAlert alarm. Access to this feature may be restricted. See 4.5 Device Setup for
means to allow/disallow user access.

MotionAlertTM Alarm

If MotionAlert is turned ON ( 4.5 Device Setup), the device activates a “Man Down” alarm if motion is not detected within 30 seconds. The Alarm LEDs flash, and the horn activates with an increasing audible frequency. MotionAlert is always turned OFF when the device is turned OFF.

Stealth Mode Sensor Life Alarm

Access to this feature may be restricted by user settings. See 4.10 Calibration for means to allow/disallow user access.
Stealth Mode disables the visual, audible and vibrating alarms. MSA recommends that this feature be left in its default “OFF” state. Stealth mode can be turned ON through the SETUP – INSTRUMENT OPTIONS menu (4.5 Device Setup). The message “Alarms OFF” flashes on the monochrome display when Stealth mode is ON. On the color display, all three alarm icons are shown as OFF.
The device evaluates the condition of the sensors during Calibration.

As the end of a sensor’s life approaches, a warning is provided. While the sensor is still fully functional, the warning gives the user time to plan for a replacement sensor to minimize downtime. The Sensor Life indicator displays during ongoing operations as a reminder of a sensor’s pending end of life.

When a sensor’s end-of-life is reached, sensor calibration will not be successful, and the user is then alerted by a Sensor Life Alarm. A flashing Sensor Life indicator displays during ongoing operations until the sensor is replaced and/or successfully calibrated.

On the monochrome display, the Sensor Life indicator appears on the display at the same position as the MotionAlert indicator. If MotionAlert is enabled (the

• indicator displays) and a Sensor Life warning or alarm occurs, the Sensor Life indicator takes priority and is shown instead.

Backlight

On the color display, each displayed gas will have its own Sensor Life indicator. If a sensor is in end-of-life warning, its indicator will be an orange . If a sensor has reached end-of-life, it is in alarm and its Sensor Life indicator will be a continuous blinking red .
See4.10 Calibration for additional details on Sensor Life determination and indication.
The backlight automatically activates when any front panel button is pressed and remains ON for the duration of user-selected timeout.

This duration can be changed using the SETUP – INSTRUMENT SETUP( 4.5 Device Setup) or through MSA Link software.

If the alarm is latching, the p button silences the alarm for five seconds. Alarms can be made latching or unlatching via MSA Link software.
False oxygen alarms can occur due to changes in barometric pressure (altitude), humidity 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.
3.9 Monitoring Combustible Gases
The device can be equipped with a catalytic combustible sensor that detects a variety of combustible gases up to 100 % LEL and displays the reading as either % LEL or % CH4. The ALTAIR 5X IR can also contain an IR combustible sensor. The IR sensor displays the reading in % Vol or %LEL.

WARNING!
If an alarm is triggered while using the device, leave the area immediately.Remaining in the area under such circumstances can cause serious personal injury or death.

The catalytic combustible, 25 % Vol Butane IR, and 100% LEL Propane IR sensors have two alarm setpoints: · HIGH Alarm · LOW Alarm
If the gas concentration reaches or exceeds the alarm set point, the device: · Alarm message displays and flashes in combination with the corresponding gas concentration:

4 Operation
· Backlight turns on · Alarm sounds (if active) · Alarm LEDs flash (if active)
The 100 % Vol IR sensors have no alarm setpoints.
3.10 Gas Exposure of 100 % LEL
When gas reading exceeds 100 % of the lower explosive limit (LEL), the device enters a Lock Alarm state and displays “XXX” in place of the actual reading.
WARNING! A catalytic combustible gas reading of “XXX” indicates the atmosphere could be above 100 % LEL or 5.00 % Vol CH4 and an explosion hazard exists. Move away from contaminated area immediately. Failure to follow this warning can result in serious personal injury or death.
For ALTAIR 5X IR devices with an enabled 100 % Vol methane IR sensor, the LockAlarm will clear, and the catalytic combustible again displays combustible concentrations when the gas sample drops to a lower level. For devices without an enabled 100 % Vol methane IR sensor, the user can clear the LockAlarm state only by turning the device OFF, and then ON again in a fresh air environment. When catalytic combustible gas reading digits appear, the device is available for measuring gases once again.
LockAlarm of the catalytic combustible sensor occurs during Bump Testing and calibration of a % Vol combustible IR sensor. After the IR sensor Bump Test, the LockAlarm must be cleared (as described above) before the catalytic combustible sensor is again able to measure and provide readings.
NOTE: Check your national standard values for 100 % LEL.
4 Operation
Device operation is dialog driven from the display with the aid of the three function buttons ( 3.2 Device Hardware Interfaces).
For more information, see the flow charts in 9 Flow Charts.
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 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 could shift.

4 Operation
The device will shut OFF after the customer acknowledges this message by pressing the p button.
Check your sampling system if this occurs and contact MSA as needed.
Users can check the operation of the sampling system anytime during operation by blocking the sampling system to generate a pump alarm.
WARNING! · Do not use the pump, sample line, or probe unless the pump alarm activates when the flow is blocked. Lack of an
alarm is an indication that a sample may not be drawn to the sensors, which could cause inaccurate readings. Failure to follow the above can result in serious personal injury or death. · Never let the end of the sampling line touch or go under any liquid surface. If liquid is drawn into the device, readings will be inaccurate and device could be damaged. We recommend the use of an MSA sample probe containing a special membrane filter, permeable to gas but impermeable to water, to prevent such an occurrence. Failure to follow this warning can result in serious personal injury or death.
4.2.1 Fresh Air Setup (FAS) at Device Turn-ON
The Fresh Air Setup (FAS) is for automatic ZERO adjustment of the device.
The FAS has limits. If a hazardous level of gas is present, the device ignores the FAS command and the device alarm activates.
The ability to perform an FAS at device turn-ON can be disabled by using MSA Link software.
NOTE: The Fresh Air Setup is not available for the CO2 sensor.
WARNING! · Do not perform the Fresh Air Setup unless you are certain you are in fresh, uncontaminated air; otherwise,
inaccurate readings can occur which can falsely indicate that a hazardous atmosphere is safe. If you have any doubts as to the quality of the surrounding air, do not use the Fresh Air Setup feature. · Do not use the Fresh Air Setup as a substitute for daily calibration checks. The calibration check is required to verify span accuracy. Failure to follow this warning can result in serious personal injury or death.

4.9 Bump Test

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.
NOTE: The Automated Test Stands cannot test the following sensors:

GALAXY Chlorine Dioxide % Vol Butane % Vol Propane % Vol Methane

GALAXY GX2 Chlorine Dioxide % Vol Butane % Vol Propane

For these sensors, use this Bump Test procedure.

Equipment
See 0.1 Accessories for ordering information for these components.
· Calibration Check Gas Cylinder(s)
See 6.3 Calibration Specifications for calibration gas target values and appropriate MSA calibration gas cylinders.
· Demand Flow Regulator(s) · Tubing appropriate for the gases to be tested · Kits containing tubing and regulators suitable for reactive and non-reactive gases are available from MSA.
Performing a Bump Test
For ALTAIR 5X IR devices with combustible % Vol IR sensors, the following gas levels should not be exceeded when used for daily Bump Tests:
· IR Butane 25 % Vol – 8 % Vol Butane Cal Check gas · IR Propane 100 % Vol – 50 % Propane Cal Check gas · IR Methane 100 % Vol – 20 % Methane Cal Check gas. · IR Propane 100% LEL 1. While the device is turned ON in a clean, fresh air environment, verify that readings indicate no gas is present. 2. From the normal measure screen press the q button to display “BUMP TEST?”. 3. Verify the gas concentrations displayed match the Calibration Check Gas Cylinder. If they do not, adjust the values
through the Calibration Setup menu. NOTE: Depending on the sensors installed, there could be one to five separate Bump Tests performed, each with a different cylinder, regulator, and tubing used. 4. Attach the demand regulator (supplied in the calibration kit) to the cylinder providing the indicated gases. 5. Connect tubing (supplied in the calibration kit) to the regulator. 6. Attach the other end of tubing to the device pump inlet. 7. Press the button to start the bump test:
the progress bar advances the sensors respond to the gas.
The message BUMP TEST PASS indicates a successful Bump Test of the sensors.
If any sensor fails the Bump Test the:
· Message BUMP TEST FAIL appears · Failed sensor is indicated.
If there are more sensors to be Bump Tested, the next sensor displays and the process repeats from Step 4.
If there are no more sensors to be Bump Tested, the tubing can be removed from the device pump inlet.
In the ALTAIR 5X IR, Bump Testing of a combustible IR sensor causes the catalytic combustible sensor to enter the LockAlarm condition. While a device with a % Vol methane IR sensor automatically recovers from LockAlarm, propane or butane IR devices do not. For these devices, clear the LockAlarm state by turning the device OFF, then ON while in a fresh air environment. See 3.9 Monitoring Combustible Gases for additional details.
After the Bump Test
After all installed sensors pass the Bump Test, the symbol displays on the -MEASURE page. This symbol appears on the:
· color display in the upper feature bar · monochrome display in the lower- right corner.

32

Altair 5X / Altair 5XiR

GB

4 Operation
If any sensor was not bump tested, or fails the Bump Test, the symbol does not display.
The color display:
· temporarily shows the symbol at each gas reading for successfully bump tested sensors · symbol is then replaced by the present gas reading.
The monochrome display does not show symbols for individual gas readings. The symbol shows for 24 hours after the Bump Test. If a sensor fails the Bump Test, calibrate the device as described in 4.10 Calibration.
4.10 Calibration
The ALTAIR 5X can be calibrated either manually using this procedure or automatically using the GALAXY or GALAXY GX2 test stand. Refer to4.10 Calibration .
The use of the demand regulators listed in 8 Ordering Information is recommended. If a new sensor has been installed, the battery pack has been depleted or a new battery pack has been installed allow sensors to stabilize for 30 minutes before calibration is performed.
WARNING! · Special conditions with toxic gases! If the device is to be checked or calibrated for reactive gases, prerequisites are
required; otherwise, incorrect calibration would result in incorrect device operation. · Reactive toxic gases (e.g., chlorine, ammonia, chlorine dioxide) have the property of diffusing into the rubber and
plastic tubes so that the volume of test gas available in the device would no longer be sufficient to correctly perform device calibration. · When calibrating the device with toxic gases, certain prerequisites are required, otherwise incorrect calibration could result:
A special pressure regulator Shortest possible connection tubes between the pressure regulator and the device Connection tubes made from a material that does not absorb the test gases (e.g., PTFE). Failure to follow these warnings can result in serious personal injury or death.
NOTE: If using normal tubes and pressure regulators, expose them to the required test gas for an extended time period. Keep these materials dedicated for use with that test gas only; do not use them for other gases.
For example, for chlorine, allow the entire contents of a test gas cylinder to flow through the pressure regulator and tubes before using to calibrate the device. Mark these materials for use with chlorine only.
4.10.1 Zero Calibration Procedure
1. Press the p button for five seconds in Normal Measurement page. ZERO screen displays.
To skip the ZERO procedure and move directly to the span calibration procedure, push the p button. If no button is pushed for 30 seconds, the device prompts user to perform a SPAN calibration before device returns to the Normal Measurement page.
To perform ONLY a Fresh Air Setup at this time, press the button. The device then performs a Fresh Air Setup as described in 4.2 Turning ON and Fresh Air Setup. When the Fresh Air Setup is complete, the device returns to the normal Measure screen.

4 Operation
2. Press the q button to confirm the ZERO screen, i. e. to execute zero calibration. The message “SENSOR REFRESH” displays, followed by the message “ZERO CALIBRATION”. The “REFRESH” message does not appear if a catalytic combustible sensor is not installed. ZERO calibration starts. A progress bar shows the user how much of the calibration has been completed.
During the first moments of a ZERO calibration, the combustible sensor reading may be replaced by a moving display of “PLEASE WAIT”. This is normal. NOTE: After the ZERO calibration is completed the device displays either
· “ZERO CALIBRATION PASS”
or
· “ZERO CALIBRATION FAIL”.

NOTE: Only if the device passes the zero calibration the SPAN screen displays.

4.10.2 Span Calibration
To skip the Span calibration procedure, push the p button.
NOTE: If the SPAN calibration of the combustible sensor is skipped after a successful ZERO calibration, the combustible sensor reading may be replaced with a moving display of “PLEASE WAIT” for a few moments. This is normal, and the device is fully operational once a combustible gas reading reappears.
If no button is pushed for 30 seconds, span calibration is skipped.
Because of the different possible combinations of gases that are possible, skipping a Span calibration could advance the user to the Span calibration of another installed sensor, or back to Measuring mode.
When calibrating with combustible gases > 100 % LEL, select the “Yes” option to prompt “Span Calibration?” BEFORE applying gas to the device.

1. Connect one end of tubing to the cylinder regulator (supplied in the calibration kit).
2. Connect the other end of the tubing to the pump inlet.
3. Press the q button to calibrate (span) the device. “SPAN CALIBRATION” flashes SPAN calibration starts. A progress bar shows the user how much of the calibration has already been completed.

Altair 5X / Altair 5XiR

GB

NOTE: After the SPAN calibration is completed, the device displays either · “SPAN CALIBRATION PASS” or · “SPAN CALIBRATION FAIL”
NOTE: The device returns to Measuring mode.

4 Operation

If a sensor is nearing its end-of-life, the “PASS” display is followed by the Sensor Life indicator display.
· While the sensor is still fully functional, this warning gives the user time to plan for a replacement sensor to minimize downtime.
· The indicator blinks as the device returns to Measure mode. · After 15 seconds, the blinking stops, but the indicator continues to display during ongoing operations as a reminder
of a sensor’s pending end-of-life.
If a span calibration fails:
· The Sensor Life Indicator blinks to show a sensor has reached its end-of- life and should be replaced. · The device remains in the Sensor Life alarm condition until the p button is pressed. · After the alarm is cleared, the device enters Measure mode and the Sensor Life indicator blinks during ongoing
operations until the sensor is replaced and/or successfully calibrated.
Span calibration can fail for reasons other than a sensor at the end of its life. If a span calibration failure occurs, verify items such as:
· sufficient gas remaining in the calibration cylinder · gas expiration date · integrity of calibration tubing/fittings, etc. 4. Reattempt the span calibration before replacing the sensor.

4.10.3 Finishing Successful Calibration 1. Remove the calibration tube from pump inlet.

The calibration procedure adjusts the span value for any sensor that passes the calibration test. Sensors that fail calibration are left unchanged.

In the ALTAIR 5X IR, a combustible IR sensor calibration causes the catalytic combustible sensor to enter the LockAlarm condition.

· While a device with a % Vol methane IR sensor automatically recovers from LockAlarm, propane and butane IR devices do not; for these devices, the LockAlarm state is cleared by turning the device OFF, then ON while in a fresh air environment ( 4.2 Turning ON and Fresh Air Setup for details)

On the color display, each successfully calibrated sensor temporarily shows a symbol at its gas reading.

These symbols remain visible for a few moments and are then replaced by the present gas reading.

The monochrome display does not show symbols for individual gas readings.

Since residual gas may be present, the device may briefly go into an exposure alarm after the calibration sequence is completed.

2. Press the p button to reset the alarm as necessary.
