A Warning identifies conditions and actions that pose
hazard(s) to the user; a Caution identifies conditions and
actions that may damage the detector.
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.

Do not mix with the solid waste stream. Spent
batteries should be disposed of by a qualified
recycler or hazardous materials handler.
BW Defender2
Safety Information - Read First
aWarning
To avoid possible personal injury:
⇒
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 plastic.
⇒
If the detector is damaged or something is missing, contact BW Technologies immediately (see p. 2).
⇒
Make sure the battery is locked in place before you operate the detector.
⇒
Use only a sensor specifically designed for your detector. (See the section, "Replacement Parts and
Accessories.")
⇒
Periodically test the sensor’s response to gas by exposing the detector to a targeted gas concentration that
exceeds the High Alarm setpoint. Manually verify that the audible and visual alarms are activated.
⇒
Prior to each day’s usage sensitivity must be tested on a known concentration of the target combustible gas
(methane, etc.) equivalent to 25-50% of full-scale concentration (accuracy must be within 0 to +20% of actual).
Accuracy may be corrected by recalibrating the instrument.
⇒
Calibrate the detector before first-time use, and then at least once every 90 days.
⇒
Do not turn off the detector during a work shift. Turning off the detector resets the LTEL (Long Term
Exposure Limit), STEL (Short Term Exposure Limit) and maximum gas exposure values to 0. (See the section,
“Alarms.”)
⇒
It is recommended that the accuracy of the detector be checked with known concentration calibration gas
before each day’s use and immediately after any known exposure to contaminants.
3
BW Defender2
User Manual
aWarnings (cont.)
4
⇒
The LEL sensor is factory calibrated to methane. If monitoring a different combustible gas, calibrate the
sensor using the appropriate gas.
⇒
High off-scale % LEL readings may indicate an explosive concentration.
⇒
Protect the LEL 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 Black & Decker VersaPak™ batteries, properly charged and installed in the detector case. (See the
section, "Replacement Parts and Accessories.")
⇒
Only charge batteries using a VersaPak™ charger (such as the D4-VP130 and V-CHARG1). 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.
BW Defender2
Safety Information - Read First
Caution
To avoid possible damage to the detector:
⇒
Extended exposure of the detector 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 sensors 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
Low Battery Alarm
The detector tests for a missing or defective sensor during the
activation self-test. See the section, "If the Detector Does Not
Work."
The detector tests the battery 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 battery
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 battery. (See the section, "Replacing the
Battery.")
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.

User Manual
Calibration and Setting Alarm Setpoints
•
Calibrate a new sensor before use. Allow the sensor to
stabilize before starting calibration (used: 60 seconds;
new: 5 minutes).
•
Calibrate the detector once every one to three months,
depending on use and sensor exposure to poisons and
contaminants.
•
Calibrate the detector if the ambient gas display varies at
start-up.
•
It is best to calibrate the sensor before changing 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 O2 sensor is automatically calibrated on activation.
Activate detector in a normal 20.9% O2 atmosphere.
•
If you require a certified calibration, contact BW
Technologies using one of the numbers on page 2.
Guidelines
Caution
The detector must be calibrated using the
following gas concentrations: H2S = 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 (four-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.
24
BW Defender2
Calibration and Setting Alarm Setpoints
Diagnostics Protection:
The detector test 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 no 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 sensor(s) 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

fail.
If a sensor fails, the display advises error (Err) and skips
the span for the failed sensor(s). Other sensors span
normally. Press
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.

warnings or other important events will not be
filtered and will appear in the final Excel Workbook
in their entirety. If the confidence beep is used on
the datalogging instrument, this step has no effect;
E.D.M. will not filter out records where the
confidence beep is active.
6. Finish: Click on ‘Finish’ to import the data into Excel and
open the finished Excel data workbook.
Note
The data file may take several minutes to transfer, read and
sort in E.D.M.

Direct Import to Compatible Programs
Information from this point on only applies to users who are
not using the E.D.M. plug-in. The following information
applies to direct data import into Excel and other compatible
programs. To use the datalogger data, insert the data card
into a computer adapter and open the data file
LOGFILE0.CSV using spreadsheet or database software.
Word processors and text editors may also be used, but
performance may be poor, since the datalogger file is at least
16 megabytes in size.
Data for user-accessible models is comma-separated-values
(CSV) format. The data order is:
• Date, day, time
• H2S, CO, LEL, O2
• H2S TWA, CO TWA
• Status Codes, serial number
The recorded data can be loaded into most spreadsheet,
database, word processor, or text editor applications, some
examples are:
•
•
•
•
•
Microsoft® Excel 95, 98 and 2000;
Quattro Pro;
Lotus 1-2-3;
Microsoft® Access; and
Microsoft® Word
Determining Application Compatibility
To determine if the application selected is compatible:
•
Insert MMC card in to the Card Reader; then
•
Open desired application.
•
Use the applications “File/Open” menu options to
locate and open the data file.
Recorded data includes eight single-character unit status
codes. The eight characters represent codes for the H2S,
CO, LEL, and O2 sensors, datalogger, unit battery status,
and unit alarm status. A summary of most of the available
codes can be seen in table A.
If the recorded data file is compatible with the application, it
will open. If not the application will report an error in opening
the file.
Importing the Data File Into Compatible
Desktop Applications
Some applications have an internal file size limits, and may
not load the entire file. Check the applications specifications
prior to use.
Information from this point forward only applies to users who
are not using the Excel Datalog Manager (E.D.M.) plug-in.
