Safety Information: Read First

WARNING

1. Substitution of components may impair Intrinsic Safety.
2. BW recommends performing a bump test prior to each day’s use to confirm sensor response and alarm activation by exposing the detector to a concentration of target gas that exceeds the low alarm set point. BW also recommends performing a bump test if the detector has been subjected to physical impact, liquid immersion, an Over Limit alarm event, custody changes, or anytime the detectors performance is in doubt. Calibrate the detector after a failed bump test. Always bump test and calibrate in a fresh air environment.
3. Detectors in hibernation mode are not functional.

CAUTION

1. Activate the detector before the activation date on the package.
2. This product is a gas detector, not a measurement device.
3. Ensure that the sensor grill is free of dirt, debris, and is not obstructed.
4. Clean the exterior with a soft, damp cloth.
5. For optimal performance, periodically zero the sensor in a normal atmosphere (20.9% v/v O2 ) that is free of hazardous gas.
6. Portable safety gas detectors are life safety devices. Accuracy of ambient gas reading(s) is dependent upon factors such as accuracy of the calibration gas standard used for calibration and frequency of calibration. BW recommends performing a calibration at least once every 180 days (6 months).

When the operating life countdown reaches 24 hours or less before expiry, the countdown display changes to hours, and the EXPIRY! warning and non- compliance symbol are displayed.

End of Operating Life

When the operating life countdown ends, the detector deactivates and detector safety functions are disabled. It is possible to retrieve event logs for a limited time after expiry. The EXPIRY! warning and non-compliance symbol are displayed for up to 30 days after expiry.

Internal Diagnostic Tests

Activated detectors automatically perform one internal diagnostic test every 24 hours. If the internal diagnostic test fails, the diagnostic fail-safe begins.

Diagnostic Fail-Safe

1. The EXPIRY! warning and non-compliance symbol are displayed.
2. The detector beeps and vibrates.
3. The LEDs flash 2 times per second for 15 seconds.
4. OFF or an error code is displayed. The detector is deactivated. It is possible to retrieve the event logs for a limited time after expiry. If you are unable to retrieve the event logs, contact BW.

Alarms and Warnings

An alarm is initiated when the sensor is exposed to a gas concentration that exceeds alarm setpoints. The alarm persists until the alarm gas concentration returns to an acceptable range. Battery life decreases rapidly when the detector is in alarm condition.

Low Alarm

Audible: 1 beep per second

Visual: 1 flash per second

Vibration: 1 vibration per second

High Alarm

Audible: 2 beeps per second

Visual: 2 flashes per second

Vibration: 2 vibrations per second

Over-Limit and Under-Limit Alarms

If the gas concentration is beyond the sensor range, OL (over-limit) or -OL (under-limit) is displayed.

Audible: 2 beeps per second

Visual: 2 flashes per second

Vibration: 2 vibrations per second

Automatic Zero Reminder for O2 Models

For O2 models only, the Automatic Zero Reminder is displayed when more than 24 hours have elapsed since the last successful zero procedure was performed.

Peak Readings

The peak readings symbol is displayed when the sensor is exposed to a gas concentration that exceeds the alarm setpoints. It is no longer displayed when more than 24 hours have passed since the last alarm, or when a successful bump test is performed via an IntelliDoX or MicroDock II station.

Non-compliance Symbol and LED Indicators

The non-compliance warning symbol is displayed when:

• an internal diagnostic test fails;
• a bump test, calibration or zero procedure fails;
• a bump test or calibration is due, if enabled;
• the sensor is exposed to a gas concentration that exceeds alarm setpoints, if enabled.

The non-compliance warning symbol is no longer displayed when more than 24 hours have passed since the last alarm, or when a successful bump test or calibration is performed (manual calibration or via an IntelliDoX or MicroDock II station). The non-compliance warning symbol is permanently displayed when the service-life countdown reaches 24 hours or less before expiry, and for up to 30 days after expiry.

When Non-compliance after gas exposure is enabled through Fleet Manager II via an IntelliDoX station, the LEDs flash in an alternating pattern when the non-compliance warning symbol is displayed. When the symbol is first displayed, the top LEDs flash. After 30 seconds, the side LEDs flash. After 30 seconds, the pattern repeats until the noncompliance warning symbol is no longer displayed.

NOTE: When the detector is bump tested via a MicroDock II station, an abnormal test result may occur if non-compliance LEDs are flashing. To suspend the flashing for up to 10 minutes, press and release the pushbutton. When the flashing stops, insert the detector and perform the test. If the bump test fails, the LEDs resume flashing.

Recall Events and Settings

When the detector is in normal operating mode, press the pushbutton at any time to scroll through events and settings that are not empty or disabled through Fleet Manager II via an IntelliDoX station. BW Clip Real Time flashes, vibrates and beeps.
While an event or setting is displayed, press the pushbutton to scroll to the next available event or setting. If you do not press the pushbutton, or if you have reached the last available event or setting, the detector returns to normal operation. Events and settings are displayed in this order:

1. Peak Reading , if available, and when a maximum gas exposure event has occurred within the past 24 hours.
2. Time of Peak Reading , if Real-time Clock display is enabled.
3. Operating Life , the remaining operating life of the detector in months, days or hours.
4. Low Alarm Setpoint
5. High Alarm Setpoint
6. Real-time Clock , if enabled.
7. Firmware Version
8. Next Bump Due , if enabled.
9. Next Calibration Due , if enabled.
10. Hibernation , for 2-year H2S and CO models only

Zero the Sensor

Over time and through use, the sensor baseline at zero exposure may drift from the manufacturer’s baseline. For optimal performance of O2 models, BW recommends that you zero the O2 sensor once every 24 hours or when the Automatic Zero Reminder is displayed. For all other models, BW recommends that you zero the sensor periodically.

Zero Procedure

1. Move to a normal atmosphere (20.9% v/v O2 ) that is free of hazardous gas.
2. Press and hold the pushbutton until a 5 second countdown is displayed, and then continue to hold until the countdown is complete.
3. When the countdown is complete, the Zero procedure begins and ZErO is displayed.
4. When Zero is successful, PASS and then CAL ? is displayed. Press the pushbutton to calibrate, or wait for the detector to enter normal operating mode after a 5 second countdown.
5. If Zero is not successful, the non-compliance LED flashes. FAIL and the non-compliance warning symbol are displayed. Press the pushbutton to acknowledge the result and return to normal operation. The non-compliance warning symbol is displayed and the non-compliance LED flashes. Perform the Zero procedure again. If the procedure fails again, contact BW.

Bump Tests

When the detector is configured to display a bump test reminder, the bump test symbol is displayed when a bump test is due. For best results, bump test the detector via an IntelliDoX or MicroDock II station. Bump tests performed via an IntelliDoX or MicroDock II station are logged as bump tests. Manual bump tests are logged as unsafe gas concentrations.

Calibration

By default, BW Clip Real Time is configured to use the following calibration gas mixtures:

You can use Fleet Manager II software via an IntelliDoX station to change a detector’s default calibration gas mixtures. If the detector’s default calibration mixtures were changed, use the gas mixture values from Fleet Manager II to calibrate the detector.

1. Move to a normal atmosphere (20.9% v/v O2 ) that is free of hazardous gas.
2. Connect the calibration hose to the gas cylinder and to the intake inlet on the calibration cap.
3. Press and hold the pushbutton until a 5 second countdown is displayed, and then continue to hold until the countdown is complete. The zero procedure begins and ZErO is displayed. When Zero is successful, PASS is displayed.
4. When CAL ? is displayed, press the pushbutton to begin calibration.
5. Put the calibration cap on the sensor grill.
6. When GAS ? is displayed, apply calibration gas for two minutes at a recommended flow rate of 500 ml/min. When calibration is successful, PASS is displayed and the detector returns to normal operating mode.

If calibration fails, non-compliance warning symbols are displayed. Press the pushbutton to acknowledge. Repeat calibration. If it fails again, contact BW.

Event Logs

The detector stores the last 35 events that occurred, including peak readings, bump tests, calibrations and auto zeros. Each record contains:

• detector serial number, sensor type and life-remaining;
• total number of events that have occurred;
• event type and duration;
• alarm level(s) in ppm or %;
• time elapsed since the alarm occurred in days/hours/minutes;
• duration of the alarm (minutes/seconds).

Use Fleet Manager II via an IntelliDoX or MicroDock II station to transfer event logs from the detector to a computer. When logs are transferred via an IntelliDoX station, the most recent 35 events are transferred. When logs are transferred via a MicroDock II station, the most recent 10 events are transferred.

Optional Settings

Use Fleet Manager II via an IntelliDoX station to enable the following optional settings for BW Clip Real Time detectors.

Non-compliance After Gas Exposure

When Non-compliance after gas exposure is enabled, the LEDs flash in an alternating pattern when the sensor is exposed to a gas concentration that exceeds alarm setpoints. When the gas exposure is detected, the top LEDs flash. After 30 seconds, the side LEDs flash. After 30 seconds, the pattern repeats until more than 24 hours have passed since the last alarm, or when a successful bump test is performed via an IntelliDoX or MicroDock II station.

Real-time Clock Display

When real-time Clock Display is enabled, you can display the current time by pressing the pushbutton to Recall Events and Settings , and then continuing to press the pushbutton until the time is displayed. Time may be displayed in 12-hour or 24-hour clock format.
