BW Technologies BW Clip Single Gas CO Monitor User Manual

1. Product Overview

The BW Technologies BW Clip Single Gas CO Monitor (Model BWC2-M) is a maintenance-free, personal safety device designed for continuous monitoring of carbon monoxide (CO) levels in industrial environments. This device provides reliable gas detection without the need for sensor or battery changes throughout its operational life.

Key features include:

• Hibernation mode for extended battery life with an optional case accessory or IntelliDoX.
• Automatic logging of the 35 most recent gas events and bump test results.
• Configurable high and low alarm set points.
• Compatibility with IntelliDoX, MicroDock II, and Fleet Manager II software for data management.

2. Setup

The BW Clip CO Monitor is designed for immediate use upon activation. No initial calibration or complex setup procedures are typically required.

2.1 Activation

The device is activated upon its first use. Follow the instructions provided on the device's display or accompanying quick start guide for the initial activation sequence. Once activated, the device will begin its continuous monitoring function.

2.2 Wearing the Device

The monitor is equipped with a durable clip for secure attachment. Attach the device to your clothing, belt, or hard hat in a location that ensures the sensor opening is not obstructed and allows for clear visibility of the display and audibility of alarms.

3. Operating Instructions

The BW Clip monitor operates continuously once activated, providing real-time gas concentration readings and alarm indications.

3.1 Continuous Monitoring

The LCD continuously displays the current CO concentration in parts per million (ppm). It also shows the remaining operational life of the device, typically indicated in months (MM).

3.2 Alarm Indications

The device is equipped with multiple alarm types to alert users to hazardous gas levels:

• Visual Alarm: Flashing LED lights.
• Audible Alarm: A loud, distinct sound (typically 95 dB).
• Vibratory Alarm: The device vibrates to provide tactile warning.

Alarms are triggered when CO concentrations exceed the pre-set low or high alarm thresholds. In an alarm condition, immediately move to a fresh air environment. The alarm will cease once the gas concentration drops below the alarm set points.

3.3 Bump Testing

Regular bump tests are recommended to verify the functionality of the sensor and alarms. A bump test involves briefly exposing the monitor to a known concentration of target gas that is above the alarm set points. Consult your organization's safety protocols and local regulations for recommended bump test frequency.

3.4 Event Logging

The BW Clip automatically stores data for the 35 most recent gas events and bump test results. This logged data can be downloaded and analyzed using compatible instrument management systems such as IntelliDoX or Fleet Manager II software.

4. Maintenance

The BW Clip is designed as a maintenance-free device, simplifying its use and reducing operational overhead.

4.1 General Care

Keep the device clean by wiping it with a damp cloth. Ensure the sensor opening is free from dust, debris, or any obstructions that could impede gas detection.

4.2 Battery and Sensor

The BW Clip features a sealed battery and sensor that are designed to last for the entire specified operational life of the device. These components are not user-replaceable, and no routine battery charging or sensor replacement is required.

4.3 Hibernation Mode

For the two-year version of the CO monitor, a hibernation mode is available. This mode allows the device to be temporarily powered down to conserve battery life when not in use for extended periods (e.g., a week or more). Hibernation can be activated using a specific case accessory or through the IntelliDoX system. Refer to the IntelliDoX manual for detailed instructions on using hibernation mode.

5. Troubleshooting

This section addresses common issues you might encounter with your BW Clip monitor.

5.1 'FAIL' Message on Display

If the device displays a 'FAIL' message, it indicates an internal error or sensor malfunction. The device should be immediately removed from service and replaced. Do not attempt to repair the device.

5.2 No Display or Unresponsive Device

Ensure the device has been properly activated. If the device has reached the end of its operational lifespan, it will cease to function and display 'END'. In this case, the device requires replacement.

5.3 Persistent Alarms or False Alarms

If the device alarms continuously or appears to be giving false alarms, move to a known fresh air environment. Ensure the sensor is not exposed to interfering gases, extreme temperatures, or humidity levels outside its specified operating range. If the alarm persists in fresh air, the device may be malfunctioning and should be removed from service.
