GETTING STARTED BATTERY GENERAL: For safety and ease of use, the battery is housed in an exterior separate battery compartment. You never have to open the monitor to change, or charge, the batteries. OPERATION: TROUBLESHOOTING Problem Possible Cause Solution Unit intermittently enters alarm without apparent reason. Ambient gas levels are near alarm point. Puff of gas. Alarms set incorrectly. Weak battery. Unit is operating normally. Use caution in suspect areas. Check maximum exposure reading.
TROUBLESHOOTING WRIST STRAP This section lists some common errors and their solutions. If you are unable to solve the problem, please contact BW Technologies for assistance. Problem Possible Cause Solution Unit will not turn ON. No battery. Battery is dead. Unit is damaged or defective. This is a 2-gas version BW DEFENDER, which does not measure toxic gases. This is a 2-gas version BW DEFENDER, which does not measure toxic gases. Alarm points are set incorrectly. Install battery.
GETTING STARTED DISPLAY ICONS GENERAL: BW DEFENDER icons and intelligent alpha-numeric display provide clear “Status at a Glance” advice at all times. Only applicable icons will be displayed at any one time. 2-GAS to 4-GAS UPGRADE GENERAL: D4-2002 (4-gas) BW DEFENDERS — operating toxic gas sensor D2-2002 (2-gas) BW DEFENDERS — “dummy” sensor The Twin Toxic sensor can be added and the BW DEFENDER programming can be changed at any time to turn a 2-gas BW DEFENDER into a 4-gas BW DEFENDER.
FIELD OPTIONS CONFIDENCE BEEP GENERAL: Once activated the Confidence Beep will BEEP once every 6 seconds to advise that it is operational. IMPORTANT: As shown in the table below, the confidence beep option reverses the normal behavior of the BW DEFENDER low battery alarm. When the confidence beep is enabled, the BW DEFENDER will emit a short beep once every 6 seconds when the battery is okay. The BW DEFENDER will not beep when the battery is low.
DEACTIVATING THE DETECTOR GENERAL: The BW DEFENDER “OFF” function is designed to prevent accidental shut off, and will warn you that the BW DEFENDER is being shut down. 1. To deactivate, press the (ON/OFF) key firmly and hold it down until the word “OFF” appears on the screen (approximately 4 seconds). OFF WARNING: Prior to the “OFF” readout the detector will emit 4 beeps and flash the alarm LEDs as a warning that the unit will be shutting down. Shut down will occur after the word “OFF” displays.
BATTERY TEST GENERAL: The BW DEFENDER continuously monitors the performance and condition of its battery. During normal operation, the unit displays “Battery OK” in the bottom left hand corner of the LCD display. LOW BATTERY ALARM: Should the unit detect a battery in the early stages of running down, the unit will emit a low battery warning alarm. (See page 14.) This warning will persist until the battery in the unit is replaced, or the battery is nearly dead.
ACCUMULATED EXPOSURE LEVELS GENERAL: The 4-gas BW DEFENDER automatically calculates the TWA (TimeWeighted-Average). Exposure of H2S and CO (toxic) gases based on the standard 8 hour work day. The BW DEFENDER also records and displays the Peak Exposure encountered for each gas. These measurements are referred to as: “AE” = Average Exposure or TWA (Time-Weighted-Average) “PE” = Peak Exposure encountered (the maximum hazard) To view: 1. Press and hold the Tab key until the letters “AE” (or “PE”) appear (5 sec.
CALIBRATION ALARM SETPOINTS GENERAL: The BW DEFENDER, designed for easy calibration, will automatically set span and zero. The LCD advises you as each automatic function takes place and when to apply calibration gas. GENERAL: Each gas detected has two user-settable alarm points. Each setpoint can be individually adjusted by the user. Each set of alarm setpoints control different aspects of the BW DEFENDER'S behavior, as described below. Alarm setpoints can be password protected.
AUDIBLE / VISUAL ALARMS MAINTENANCE GENERAL: Distinguish audibly and visually which gas hazard(s) is present, the alarm level(s) and type(s) of alarm: LOW, TWA, HIGH, or Multi-Gas alarm. During the different gas alarm pattern, the alarm LEDs blink on and off as the speaker sounds. The speaker tone changes from a low tone to a high tone in a repeating pattern. The backlight is on, and remains on for the duration of the alarm condition.
FIELD OPTIONS AUTO ZERO GENERAL: The BW DEFENDER sensors can be AUTO ZEROED without the use of calibration gas. In a clean, normal environment free of background gases, initiate the Calibration procedure (see page 23). All the sensors will be Auto Zeroed. OTHER ALARMS GENERAL: In addition to the gas hazard alarms, the BW DEFENDER provides a distinct alarm warning if the battery power is low, and to announce a missing sensor.
DAILY OPERATION 1. Turn your BW DEFENDER “ON”. All features and functions are activated. Leave the BW DEFENDER ON for the entire work shift to collect TWA (Time Weighted Average) and PEAK Exposure data. 2. In the event of a hazardous gas alarm take appropriate precautions immediately. A gas alarm takes priority over any other types of alarms. 3. TEST ALARMS: Verify proper alarm function prior to use with BW’s “Bump” Alarm Test Gas.
MANUAL ASPIRATOR PUMP GENERAL: The manual aspirator option is an inexpensive method of adding remote sampling capabilities to a BW DEFENDER . The Aspirator Pump and Sampling Hose are joined by a simple quick connect. The D4-AS01 Aspirator Pump is equipped with the squeeze bulb and an in-line water trap (Order #: D4-WT-1) When ordered, the D4-AS01 includes a D4-HAS-10 10 ft. (3.1m) sampling hose (longer lengths available). The Sampling Hose is equipped with a Particulate Filter (Order #: D4-PF-1).
SAMPLING PUMP 1. Attach the Sampling Hose or Sampling Probe directly to the Sampling Pump. Turn the quick connect right to lock into place. TO ACTIVATE THE PUMP 2. Simply slide the thumbswitch fully to the right closing the vents. The pump will automatically turn ON, drawing the sampled air across the sensors. The Sampling Pump Fan Icon will light. During pump operation, the BW DEFENDER will display the FAN icons in a “spin” pattern. This indicates that the pump is operating normally.
