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. Before you use the detector, inspect the case. Look for cracks or missing

parts.

⇒ If the detector is damaged or something is missing, contact BW Technologies immediately (see p. 2).

⇒ Make sure the battery holder is locked in place before you operate the detector.

⇒ Use only a sensor specifically designed for your GasAlertMicro model. (See the section “Replacement Parts and

Accessories.”)

⇒ Calibrate the detector before first-time use and then on a regular schedule, depending on use and sensor

exposure to poisons and contaminants. BW recommends at least once every 180 days (6 months).

⇒ It is recommended that a “bump test” be performed before each day’s use to verify proper instrument operation.

Calibrate if the readings are not within the specified limits.

⇒ Periodically “bump test” the sensors to confirm their ability to respond to gas by exposing the detector to a

targeted gas concentration that exceeds the high alarm setpoints. Manually verify that the audible and visual alarms are activated.

⇒ It is recommended 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.).

3

GasAlertMicro

Users Manual

a

Cautions (cont.)

⇒ 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. 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.

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.

⇒ Any rapid up-scaling reading followed by a declining or erratic reading may indicate a gas concentration beyond

upper scale limit, which may be hazardous.

⇒ Use only recommended AA alkaline or NiMH batteries properly charged, and installed in the detector case. (See

the section “Replacement Parts and Accessories.”)

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

precaution could 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

may lead to fire or explosion.

⇒ Read and observe all instructions and precautions in the literature provided with the charger. Failure to do so may

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

4

GasAlertMicro

Safety Information - Read First

a

Cautions (cont.)

⇒ Extended exposure of the GasAlertMicro to certain 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, recalibration should be performed, or if needed, the sensor replaced.

⇒ Do not test the combustible sensor’s response with a butane cigarette lighter; doing so will damage the sensor.

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

⇒ Do not attempt to disassemble, adjust or service the detector unless instructions for that procedure are contained

in the manual and/or that part is listed as a replacement part. Use only BW Technologies replacement parts.

⇒ Do not immerse the detector in liquids.

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

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

Sensor Alarm

The detector tests for a missing or defective sensor during the activation self-test. See the section “If the Detector Does

Not Work.”

Low Battery Alarm

The detector tests the batteries on activation and continuously thereafter. If the battery voltage is low, the detector activates the Low Battery Alarm.

The Low Battery Alarm continues until you replace the batteries or the battery power is almost depleted. If the battery voltage drops too low, the detector executes an

Automatic Shutdown.

Automatic Shutdown Alarm

If the battery voltage is in immediate danger of dropping below the minimum operating voltage, the audible alarm beeps 8 times and the visual alarm flashes 8 times. After

3 seconds, the display blanks out and the detector stops normal operation. The display shows I LOW periodically until the battery power is depleted.

Replace the batteries. (See the section “Replacing the

Batteries.”)

Note: If the Confidence Beep is ON, the audible alarm does not beep during a Low Battery alarm. (See the section

“Confidence Beep.”) Typically, the Low Battery Alarm continues for 30 minutes before Automatic Shutdown.

Calibration and Setting Alarm Setpoints

Guidelines

Caution

The detector must be calibrated using the following gas concentrations: H

2

S = 25 ppm, CO = 100 ppm, methane =

2.5% (50% LEL) and balance air.

If you do not calibrate all of the sensors, use the gas concentration listed above for the target sensor being calibrated.

When calibrating the detector, adhere to the following guidelines:

•

CG-Q58 Calibration Gas (4-gas mix) is available from

BW Technologies. (See the section “Replacement Parts and Accessories.”)

• 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. Allow the sensor to stabilize before starting calibration (used: 60 seconds; new: 5 minutes).

GasAlertMicro

Calibration and Setting Alarm Setpoints

•

Calibrate the detector on a regular basis, depending on use and sensor exposure to poisons and contaminants.

BW recommends at least once every 180 days.

• Calibrate the detector if the ambient gas display varies at startup.

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

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

• To disable an alarm, set its alarm setpoint to 0.

•

The combustible sensor is factory calibrated 0 to 100%

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

•

The

2

sensor is automatically calibrated each time on activation. Activate detector in a normal 20.9% O

2 atmosphere.

• If you require a certified calibration, contact

BW Technologies using one of the numbers on page 2.

Users Manual

Diagnostics Protection

The detector tests the ambient air (Auto Zero) and the test gas applied (Auto Span) to ensure it meets expected values.

In Auto Zero, if any background target gas is present, the sensor(s) affected will read "Err" and exit the Auto Zero function, retaining the previous set value(s).

In Auto Span, if any target gas is not present or does not meet expected values, the display will advise you and exit calibration mode, retaining the previous set value(s).

Applying Gas to the Sensors

The calibration hose, which is shipped with the detector, simplifies sensor testing and calibration. Table 10 and Figure

3 show how to use it when applying gas to the sensors.

Calibration Procedure

To calibrate the detector and set its alarm setpoints, perform the following:

Start Calibration

To quit at any point after auto zero, press A. The detector retains any saved values, and the audible alarm beeps

4 times before the detector returns to normal operation.

1. Press C and H simultaneously. The detector beeps

4 times and the display shows:

The audible alarm then beeps once.

GasAlertMicro


Auto Zero and Oxygen Sensor Calibration

The display flashes “Auto Zero” while the detector automatically zeroes the H

2

S, CO and combustibles sensors and calibrates the oxygen sensor.

The audible alarm then beeps twice.

Auto Zero Sensor Fail

Note: Do not apply the calibration gas until the display shows a flashing gas cylinder; otherwise, the auto zero step will fail.

If a sensor fails, the display advises error (Err) and skips the

span for the failed sensor(s). Other sensors span normally.

Press A to exit, then restart calibration in an atmosphere

that is clear of the targeted gases. If the auto zero fails a second time, restart the detector to test the sensors.

31

GasAlertMicro

Users Manual

Pass Code Protect: If the detector is pass code protected, after a successful Auto Zero, the detector will ask for the pass code before proceeding to Auto Span and Alarm

Setpoints.

Pass Code Protect Activated

Before setting span, the display will advise if the detector is pass code protected. The display will advise

Calibration is locked.

Then display requests the Pass Code.

If the pass code is not entered within 10 seconds or the wrong pass code is entered, the detector advises the code is

Not COrrEct.

The detector beeps 5 times and automatically returns to normal operation.

The Set up/down arrow icon lights to prompt entry of the

3 digit pass code. Enter the correct pass code using G and

H

keys. Press C key to accept the displayed pass code.

If the correct code is entered, the detector automatically proceeds to Auto Span.

32

Auto Span

Calibrate one, two, three or four sensors as desired.

The display shows a flashing gas cylinder, prompting you to apply a calibration gas to the sensor or skip the span

(sensitivity adjustment):

Use a calibration gas containing the gas concentrations listed in the Guidelines.

2. Install calibration cap and apply gas to the sensor at a flow rate of 250 to 500 ml/min. Or, press C now to skip the span.

When the detector senses approximately one-half of the expected gas concentration (30 seconds), the audible alarm beeps once. The detector then begins spanning the sensor

(2 minutes).

The audible alarm beeps 3 times at the end of the span.

GasAlertMicro


Note: The detector will not span a sensor if:

•

You do not apply gas to the sensor.

• The sensor fails to detect at least one-half of the

expected gas concentration in the first 30 seconds.

• The gas concentration drops below one-half of the

expected gas level during the 2 minute span.

If you apply gas to a sensor and the detector fails to span the sensor, repeat the calibration process using a new gas cylinder. If the sensor fails the span a second time, replace the sensor. (See the section “Replacing a Sensor or Sensor

Filter.”)

Warning

To avoid personal injury, use only sensors specifically designed for the detector. See the section

“Replacement Parts and Accessories.”

Each sensor has a high degree of resistance to common vapors and gases. A sensor will most likely clear itself if you remove the detector to a clean environment and wait 10 to

30 minutes. Do not expose a sensor to the vapors of inorganic solvents (such as paint fumes) or organic solvents.

The section “If the Detector Does Not Work” describes problems caused by a sensor in need of calibration or replacement.

Gently rocking the sensor back and forth may help free a tightly held sensor. Insert new sensor on the PCB, ensuring that sensor posts are aligned correctly. Two-gas units require a dummy sensor.

Calibrate the detector after changing any sensor.

MultiMediaCard Compatibility

A standard 32MB MMC Flash Memory card is supplied with the datalogger. When purchasing additional

MultiMediaCards, BW Technologies recommends MMC

Flash Memory cards that contain between 32 MB and

128 MB storage capacity.

MultiMediaCard(s) compatible with the “MMC“ specification will always have the exact word “MultiMediaCard“ or “MMC“ written on the disk or package. Cards that do not contain these exact words are not a MultiMediaCard.

The “MMC“ is not the same as the following:

• MultiMedia card;

• Multi media card;

• SmartMedia

• CompactFlash

• Memory Stick

MMC cards are available through retailers throughout the world. They are also available through mail order and

Internet vendors.

60

Troubleshooting

A new MMC Card is automatically formatted when it is installed in the detector. When installing any new or blank

MMC card into the datalogger, detector LCD will display

“CARD IS BLANK”,” then the datalogger will proceed to autoformat the MMC card.

Recovering Data Files

If the MMC card is reformatted or erased accidentally by your computer application, the recorded data file can be recovered.

FIRST: First ensure the card is installed properly in the card reader. If the recorded data file is not visible ensure that:

The card reader is visible in the My Computer window.

• If not, verify that the card reader is installed correctly and that the connections are secure.

• In the “Removable Disk” drive window, ensure All Files is selected in the File Types field.

• “Reformat and Recover Deleted Files”

Place the MMC card back into the detector. The detector will reformat. The file should now be available.

GasAlertMicro

Troubleshooting

If the Recorded Data File (Logfile.csv), is still not visible:

• Format MMC card in Windows.

• Remove MMC card from the card reader.

• Insert MMC card back into the GasAlertMicro datalogger.

• Allow datalogger to reformat the MMC card.

• Remove MMC card from datalogger.

• Insert MMC card back into card reader.

• Select My Computer icon.

• Select the drive that corresponds to the card reader.

• The Recorded Data File (Logfile.csv), will now be visible.

If the Recorded Data File is still not visible, insert the MMC into the detector and turn on the instrument. The screen will advise: “Error. Data file has been deleted.” You will then be given the choice of erasing or restoring the data. Use G or

H

to scroll through the options. Press C to confirm your choice.

To restore the data, select “Restore.” The instrument will then restore the data to the MMC, and the detector will resume the start-up procedure.

Users Manual

To permanently erase the data on the MMC, select “Erase.”

The display will then read, “Are you sure?”

Press tab (C) to confirm your choice or A to abort. If you choose to abort the erasing procedure, the display will read,

“Erase aborted.”

If the MMC is full, the display will then read “Note: Card cannot be used.” Insert a new card or erase the data. Once you confirm your decision to erase the data on the MMC, the data will be permanently erased from the MMC, and the detector will resume normal operation.
