A single button controls all primary functions, allowing for intuitive operation even in challenging conditions. The back of the device includes a robust clip for attachment to clothing or equipment.
Setup
Battery Installation
The ALTAIR 2XT requires 1 Lithium Metal battery for operation. Batteries are not included with the initial purchase. Refer to the device's battery compartment for correct polarity and installation instructions. Ensure the battery compartment is securely closed after installation to maintain the device's IP67 rating.
Initial Power-On
Upon first power-on or after a battery replacement, the device will perform a self-test. Follow any on-screen prompts. Ensure the device is in a fresh air environment during initial startup to allow for proper sensor zeroing.
Operation
Basic Operation
The ALTAIR 2XT is operated using a single button. Press and hold the button to power on/off the device. Short presses navigate through menus or acknowledge alarms. The large LCD display provides real-time readings of Carbon Monoxide (CO) and Hydrogen Sulfide (H2S) concentrations.
Alarm Conditions
The device is equipped with an audible alarm to alert users to hazardous gas levels. Alarm thresholds are set as follows:
- Carbon Monoxide (CO): Low alarm at 25 ppm, High alarm at 100 ppm.
- Hydrogen Sulfide (H2S): Low alarm at 10 ppm, High alarm at 15 ppm.
When an alarm condition is met, the device will emit an audible alert. Acknowledge the alarm by pressing the button. Always follow your company's safety protocols when an alarm is triggered.
Backlight
The display features a 10-second backlight for improved visibility in low-light conditions. The timeout duration can be adjusted through the device settings.
Maintenance
Bump Testing and Calibration
Regular bump testing and calibration are crucial for ensuring the accuracy and reliability of your gas detector. The ALTAIR 2XT is designed for easy integration with the MSA GALAXY GX2 Automated Test System, which simplifies these routine maintenance tasks. Refer to the MSA GALAXY GX2 system manual for detailed instructions on automated testing.
Sensor Life and Replacement
The Xcell Sensors in the ALTAIR 2XT have an expected life of 4 years. The device's display will indicate the remaining sensor life in months. When sensors approach their end-of-life, they should be replaced by qualified personnel to maintain accurate readings and device functionality.
Cleaning and Storage
Clean the exterior of the device with a damp cloth. Do not use abrasive cleaners or solvents. Store the device in a clean, dry environment within the specified operating temperature range when not in use.
Troubleshooting
This section provides general guidance for common issues. For more complex problems, refer to the full technical manual or contact MSA customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Dead or improperly installed battery. | Check battery installation; replace battery if necessary. |
| Inaccurate gas readings. | Sensors require calibration or are at end-of-life. | Perform a bump test or full calibration. Consider sensor replacement if readings remain inaccurate. |
| Alarm sounds continuously. | Presence of target gas; sensor fault. | Evacuate to fresh air if gas is present. If in fresh air, perform a bump test. If issue persists, contact support. |
