IntroductionThe operator’s manual provides basic information to operate the GasAlertMax XT gas detector. For complete operating instructions, refer to the GasAlertMax XT Technical Reference Guide provided on the CD-ROM. The GasAlertMax XT gas detector (“the detector”) is designed to warn of hazardous gas levels above user-defined alarm setpoints.

The detector is a personal safety device. It is your responsibility to respond properly to the alarm.

Note

The detector is shipped with English as the default displayed language. Additional languages provided are French, German, Spanish, and Portuguese. The screens for the additional languages are displayed on the detector and in the corresponding operator’s manual.

sAlertMax XTerator’s Manual

Calibrate only in a safe area that is free of hazardous gas.The combustible sensor is factory calibrated to 50% LEL methane. If monitoring a different combustible gas in the % LEL range, calibrate the sensor using the appropriate gas.Only the combustible gas detection portion of this instrument has been assessed for performance by CSA International.Protect the combustible sensor from exposure to lead compounds, silicones, and chlorinated hydrocarbons. Although certain organic vapors (such as leaded gasoline and halogenated hydrocarbons) may temporarily inhibit sensor performance, in most cases, the sensor will recover after calibration.BW recommends that the combustible sensor be checked with a known concentration of calibration gas after any exposure to contaminants/poisons such as sulfur compounds, silicon vapors, halogenated compounds, etc. BW recommends to bump test the sensors before each day’s use to confirm their ability to respond to gas by exposing the detector to a gas concentration that exceeds the alarm setpoints. Manually verify that the audible and visual alarms are activated. Calibrate if the readings are not within the specified limits.Caution: High off-scale LEL readings may indicate an explosive concentration.Any rapid up scaling reading followed by a declining or erratic reading may indicate a gas concentration beyond upper scale limit, which can be hazardous.
