Note You can disable an alarm by setting the alarm setpoint to 0 (display: - -). Stopping a Gas Alarm The low, high, and STEL alarm stops when the ambient gas level returns to the acceptable range. The detector computes the TWA value based on an 8-hour workday. Only deactivating the detector can stop the TWA alarm.
GasAlertMax Alarms Pump Failure Alarm Automatic Shutdown Alarm This alarm activates if the startup pump test has failed or the pump is missing/broken. If the battery voltage is in immediate danger of dropping below the minimum operating voltage, the audible alarm beeps eight times and the visual alarm flashes eight times. After 3 seconds, the LCD blanks out and the detector stops normal operation. The display shows I LOW periodically until the battery power is depleted.
GasAlertMax User Manual Calibration and Setting Alarm Setpoints • Calibration accuracy is never better than the calibration gas accuracy. BW Technologies recommends a premium-grade calibration gas. Gases with NIST (National Institute of Standards and Technology) traceable accuracy will improve the validity of the calibration. Do not use a gas cylinder beyond its expiration date. • Calibrate a new sensor before use.
GasAlertMax Calibration and Setting Alarm Setpoints • Calibrate only in a clean atmosphere, which is free of background gas. • To disable an alarm, set its alarm setpoint to 0. • The LEL sensor is factory calibrated to methane. If monitoring a different combustible gas, calibrate the sensor using the appropriate gas. • The oxygen sensor can be automatically calibrated on activation if this feature is enabled. Activate detector in a normal (20.9% O2) atmosphere.
GasAlertMax User Manual Diagnostics Protection The detector tests the ambient air (auto zero) and the test gas that is applied (auto span) to ensure it meets expected values. If a significant level of background target gas is present during an auto zero, the sensor(s) affected will read Err and exit the auto zero function while retaining the previous set value(s).
GasAlertMax Calibration and Setting Alarm Setpoints Auto Zero and Oxygen Sensor Calibration Calibration Procedure To calibrate the detector and set its alarm setpoints, perform the following procedure. Note To quit at any point after the auto zero, press C to exit auto span. Then press F to exit setting alarm setpoints. The detector retains any saved values and the audible alarm beeps four times before the detector returns to normal operation. 3.
GasAlertMax User Manual Pass Code Protect Activated After a successful auto zero, the detector asks for the pass code if the detector is pass code protected. The pass code needs to be entered before proceeding to auto span and alarm setpoints. 4. The LCD displays that calibration is locked. It then requests the pass code. (Refer to the Entering the Pass Code section.) 36 Note If the correct code is entered, the detector automatically proceeds to auto span.
GasAlertMax Calibration and Setting Alarm Setpoints Auto Span The LCD displays K prompting you to apply the calibration gas to the sensors or you can skip the span (sensitivity adjustment). Use a calibration gas meeting the recommended gas mixture as listed in the guidelines. 5. Apply gas to the sensor at a flow rate of 250 to 500 ml/min. OR Press C to skip the span. Note The detector will not span a sensor if: • You do not apply gas to the sensor.
GasAlertMax User Manual Setting the Alarm Setpoints Note TWA, STEL, low, and high alarm setpoints are set for each sensor in the following order: H2S, CO, LEL, and O2. TWA and STEL do not apply to LEL and O2. The LCD first displays the TWA alarm setpoint for H2S. The set up/down arrow icon lights, prompting you to input a new TWA alarm setpoint. 6. To change the TWA alarm setpoint, press H or G until the LCD displays the new value. 7. Press C to save the displayed value. 8.
GasAlertMax Calibration and Setting Alarm Setpoints Setting the Calibration Due Date After all the alarm setpoints have been set, the LCD displays the number of days remaining before the next calibration is due.
