Safety Information - Read First

Use the detector only as specified in this manual otherwise the protection provided by the detector may be impaired.

International symbols used on the detector and in this manual are explained in Table 2.

Read the Warnings and Cautions on the following pages before using the detector.

ec Note

This instrument contains batteries. Do not mix with the solid waste stream. Spent batteries should be disposed of by a qualified recycler or hazardous materials handler.

GasAlertMicro

Safety Information - Read First

a Cautions

⇒ Warning: Substitution of components may impair Intrinsic Safety.

⇒ Do not use the detector if it is damaged. Inspect the case before use. Look for cracks and missing parts.

⇒ If the detector is damaged or parts are missing, contact

⇒ Ensure the battery compartment is locked in place before operating the detector.

⇒ Use only a sensor that is specifically designed for the GasAlertMicro model. Refer to

Accessories.

⇒ Calibrate the detector before first-time use and continue on a regular schedule. The schedule will depend upon

use and sensor exposure to poisons and contaminants. BW recommends that calibration be performed a minimum of once every 180 days (6 months).

⇒ 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 high alarm setpoints. Manually verify that the audible and visual alarms are activated. Calibrate if the readings are not within the specified limits.

⇒ BW recommends that the combustible sensor be checked with a known concentration of calibration gas after

any known exposure to catalyst contaminants/poisons (sulfur compounds, silicon vapors, halogenated compounds, etc.).

⇒ 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 selected gas. High off-scale % LEL or % v/v methane readings may indicate an explosive concentration.

⇒ Protect the combustible sensor from exposure to lead compounds, silicones, and chlorinated hydrocarbons.

Selected organic vapors (ie. leaded gasoline and halogenated hydrocarbons) may temporarily inhibit sensor performance. However, in most cases the sensor will recover after calibration.

BW Technologies immediately.

Replacement Parts and

GasAlertMicro

User Manual

aCautions (cont.)

⇒ Any rapid up-scaling reading that is followed by a declining or erratic reading can indicate a gas concentration

beyond upper scale limit. It may be hazardous!

⇒ Use only recommended AA alkaline or NiMH batteries that are properly charged and installed in the detector

case. Refer to

⇒ Charge NiMH batteries using the recommended charger only. Do not use any other charger. Failure to observe

this precaution can lead to fire or explosion.

⇒ Do not change or charge batteries in a hazardous location. Doing so will impair the Intrinsic Safety of the unit

and can lead to fire or explosion.

⇒ Read and observe all instructions and precautions that are provided with the charger. Failure to do so can

result in fire, electric shock, or other forms of personal injury and property damage.

⇒ Extended exposure of the GasAlertMicro to high concentrations of combustible gases and air may stress a

detector element, which can seriously affect its performance. If an alarm occurs due to high concentration of combustible gases, recalibrate immediately. If required, replace the sensor.

⇒ Do not test the combustible sensor response with a butane cigarette lighter. This will damage the sensor.

⇒ Do not expose the detector to electrical shock or severe mechanical shock.

⇒ Do not attempt to disassemble, adjust, or service the detector unless instructions in the User Manual are

provided to perform a procedure, or if a part is listed as a replacement part. Use only

replacement parts.

⇒ Do not immerse the detector in liquids.

⇒ The detector Warranty will be voided if a customer, personnel, or third parties damage the detector during

repair attempts. Any Non-BW Technologies repair/service attempts will void this Warranty.

Calibration Guidelines

When calibrating the detector adhere to the following guidelines:

• Recommended gas mixture: CO: 10 to 500 ppm balance N H

S: 10 to 100 ppm balance N

SO2: 10 to 100 ppm balance N2 LEL: 10 to 100% LEL or 0.5 to 5% by vol. methane balance air O

: Clean air, 20.9 %

• CG-Q58-4 and CG-Q34-4 calibration gas (4-gas mix) are available from BW Technologies. Refer to

Replacement Parts and Accessories.

• Calibration accuracy is never better than the calibration gas accuracy. BW Technologies recommends a premium-grade calibration gas. Gases with National Institute of Standards and Technology (NIST) traceable accuracy improve the validity of the calibration. Do not use a gas cylinder beyond its expiration date.

GasAlertMicro

Calibration and Setting Alarm Setpoints

• Calibrate a new sensor before use. Install the sensor, activate the detector, and allow the sensor to stabilize before starting calibration (used: 60 seconds; new: 5 minutes).

• Calibrate the detector on a regular basis, depending upon use and sensor exposure to poisons and contaminants. BW recommends at least once every 180 days (6 months).

• Calibrate the detector if the ambient gas display varies at start-up (readings are above or below zero).

• It is advisable to calibrate the sensor before changing the alarm setpoints.

• Calibrate only in a clean atmosphere that is free of background gas.

• To disable an alarm, set the corresponding alarm setpoint to zero.

• The combustible sensor is factory calibrated from 0-100% LEL using methane. If monitoring a different combustible gas in the 0-100% LEL range, calibrate the sensor using the appropriate gas.

• The oxygen sensor can be automatically calibrated each time upon activation (if this feature is enabled). Activate the detector in a normal (20.9% oxygen) atmosphere.

• If a certified calibration is required, contact

BW Technologies.

• Prior to calibration or a bump test, the detector must stabilize after activation for 1 minute.

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.

In auto span, if any target gas is not present or does not meet expected values, the LCD will display an error message and exit calibration mode. The previous value(s) will be retained.
