Intended use

Dräger X-am^® 8000 is a portable gas detector for clearance measurements and for the continuous monitoring of the concentration of several gases in ambient air in the workplace and in explosion-hazard areas.
X-am 8000 can measure up to 7 gasses in accordance with the installed DrägerSensors (EC, IR, CatEx, PID). The gas detector can be operated in pump mode (if it is equipped with a pump) or in diffusion mode.

Limitations on use

The gas detector is not suitable for measuring process gasses.
Operation of the gas detector in the charging cradle in a vehicle is only permitted under the following conditions:

Signalling concept

Acoustic life signal

A periodic acoustic signal indicates that the device is functional. The acoustic life signal can be disabled. For further information, see the following chapter: "Activating silent mode"

Visual life signal
A periodic pulse (increasing and decreasing intensity) of the green LED indicates:

• Measurement, clearance measurement, leak search or benzene/pre-tube measurement application active
• There is no device or channel error, no gas alarm and no special state

Visual life signal with activated D-Light
An activated D-Light feature allows the user to also check and indicate compliance with certain settings:

• Evaluation of bump test intervals activated and complied with (factory setting) or evaluation of the calibration intervals active and complied with
• Usage interval complied with The D-Light feature can be activated using the Dräger CCVision PC software.

Signalling visually corresponds to the life signal.
If one of the conditions listed is not fulfilled and the D-Light is activated, the greed LED will switch on briefly at regular intervals (short flash approx. every 60 s) instead of pulsing periodically.
When transmitting device information via Bluetooth^® the gas alarm is disconnected from the evaluation of the D-Light status.

Switch the gas detector on or off

Initial start-up
When the gas detector is switched on for the first time, a wizard starts. The wizard guides the user through the set-up of the gas detector:

• Language selection, if applicable
• Data format and date
• Time

Then carry out an initial calibration. For further information see: "Calibrating the gas detector".

Switching on the gas detector

1. Hold down the OK button for approx. 3 s.
   The display shows a countdown.
   The switch-on sequence and the warm-up phase of the sensors start.

The following display appear one after the other:

• Start screen
• Firmware version
• Display test (the display alternates between black and white)
• Alarm element test (LEDs, alarm signal and vibration alarm)
• Customer-specific information screen (optional and configurable with the Dräger CC-Vision PC software)
• Alarm thresholds, STEL, TWA (if configured) and LEL factor (if available)
• Any expired bump test or calibration interval as well as early warnings (if configured)
• Measured value display

The remaining sensor warm-up time is displayed in the upper, left-hand corner in a yellow box.

Incorrect device feature/settings!
Incorrect device features/settings may result in danger to life and/or risk of explosion.
► Before every use, check whether the display elements, the alarm features and information are displayed correctly. If one of the items listed above does not feature correctly or is incorrect, do not use the gas detector and have it inspected.

The following features are active during the sensor warm-up phase:

• The measured values flash
• The yellow LED is illuminated
• A warning notice is displayed

The gas detector is ready to measure when the measured values no longer flash and the yellow LED is no longer illuminated. The warning notice may continue to be displayed if warnings are pending. For further information see: "Opening information".
No alarms are issued during the warm-up phase!

Switching off the gas detector

1. Hold down ▲ and ▼ simultaneously until the displayed countdown expires.
   The visual, acoustic and vibration alarms activate briefly.
   The gas detector is switched off.
   Or

1. Select in measuring mode and confirm the dialog.
2. Select and confirm Switch off.

The gas detector may only be switched off without a prior sign-on if the Switch-off allowed feature is activated using the Dräger CC-Vision PC software. Factory setting: activated
The gas detector switches off automatically when it is placed in the charging cradle (factory setting). As an option, this setting can be deactivated using the Dräger CC-Vision PC software.
If the gas detector remains off for longer than 21 days and is not charged, deep sleep mode is activated. In deep sleep mode, the gas detector can no longer be switched on using the Dräger CC-Vision PC software or the Dräger X-dock. In this case, the gas detector must be switched on manually. The sensors then go through their warm-up phase.

Log user in or out

The gas detector has four configurable user levels. The user levels can be set using the Dräger CC-Vision PC software. User level 0 means that the user is not signed on. User levels 1 to 3 require a password for sign-on.
The following passwords are created by default:

Preparations for operation

Serious damage to health
An incorrect calibration can lead to incorrect measured values, which may result in serious damage to health.
► Before performing safety measurements, check the calibration using a bump test, adjust as necessary, and check all alarm elements. If national regulations exist, the bump test must be performed in accordance with these regulations.
► If the unit is permanently in the charging cradle while being operated, then the bump test must be carried out again after 4 weeks at the latest and also if the location of the device is changed.

Malfunction of pacemakers or defibrillators Magnets can have a negative impact preventing pacemakers and implanted defibrillators from working properly.
► Do not have calibration and pump adapters anywhere near pacemakers or implanted defibrillators (e.g. by attaching them to the shoulder strap).
► All persons concerned (e.g. persons with pacemakers)
The gas detector can be switched on again in the charging cradle and is then supplied with electrical current during operation.

1. Switch on the gas detector. The current measured values are shown in the display.
2. Observe warnings, error messages and special states.
3. Verify that the gas inlet openings and membranes are clean, freely accessible, dry and undamaged.
4. Check that the date and time are set correctly.

During operation

Danger to life and/or risk of explosion!
The following alarms indicate a danger to life and/or risk of explosion:

• A2 alarm
• STEL or TWA alarm
• Device/channel error
  ► Immediately leave the hazard area.

Incorrect measured values!
Only for diffusion mode: If water seals the gas inlets on the gas detector (e.g. in heavy rain or if the gas detector is submerged in water), incorrect measured values may be returned.
► With the display facing downward, shake the gas detector to remove the water.

Incorrect measured values!
A different reading may be shown if the gas detector experiences a considerable impact or a significant vibration.
► When using a CatEx or IR sensor in the gas detector, a zero-point and sensitivity calibration must be carried out after experiencing an impact load that results in a nonzero display when exposed to fresh air.
► If a deviation of the measured value from the calibration value of more than ± 5% of the reading is identified before confirming the span calibration of the CatEx sensor, the sensor must be removed from operation.
As an option, the Dräger CC-Vision PC software can be used for adjustment so that any impact detected leads to a channel error for all sensors. These channel errors are deleted after calibration. If the sensor should be irreparably damaged, then this could result in a calibration error.
Only using Bluetooth^® or API applications is insufficient for raising the alarm in safety-critical applications. Raising the alarm on the gas detector is decisive. Contact Dräger for a description of the API interface.
The use of Bluetooth® function and the API application are not part of the technical suitability test.

High readings outside of the LEL display range or a protection alarm may indicate an explosive concentration.
If the concentrations of combustible gases are too high, this may be the result of a lack of O2.
The IP degrees of protection do not extend to instances in which the equipment detects a gas during or after its exposure to these conditions. In the case of dust deposits and contact with water by immersion or a jet of water, check the calibration and functional integrity of the device.
In the event of overgassing beyond the sensor's measuring range, the zero-point and the sensitivity must be checked and, if necessary, a calibration must be performed.
The PEAK, STEL and TWA evaluations are interrupted if the menu is selected or in the case of the special state of a pump leak test. For a flawless calculation of the evaluations, only operate the gas detector in normal measuring mode. Selecting the quick menu has no influence on the PEAK, STEL and TWA evaluations.
If the gas detector is used for offshore applications, it must be kept at least 5 m away from compasses.

Monitoring measuring mode
In normal measuring mode, the measured values are displayed for every measurement gas (see Graphic E on the fold-out page). The life signal sounds at regular intervals (configurable) and the green LED pulses (e.g. visual life signal or D-light feature).
If a measuring range is exceeded or not reached, the respective symbol is displayed instead of the measured value. For further information, see the following chapter: "Symbol explanations"
If, in measuring mode, a event (e.g. an alarm) occurs, the respective symbol is displayed in the status bar (after the event is acknowledged, if necessary).

Displaying the measuring channel
To display an individual measuring channel:

1. Select in measuring mode.
2. Use ▲ or ▼ to view the individual measuring channels.
3. Select to navigate to the measuring channel overview.

Opening the event report
If the gas detector is switched off and then on again, the event report is deleted.
The following events are counted and displayed: A1/A2, STEL, shocks, incorrect password entries.
To open the event report:

1. Select > Info > Device information in measuring mode.
2. Use ▲ or ▼ to scroll through the individual pages until the event report.
   The symbol indicates a failed sign-on only after 5 attempts.

Activating the pump
To activate the pump in (normal) measuring mode:

1. Check the sealing surfaces of the pump adapter to ensure they are undamaged.
2. Place, align and tighten the pump adapter on the thread port on the top cover. Check that the pump adapter is mounted correctly. Avoid bending the pump adapter. The gas detector automatically switches to pump mode as soon as the pump adapter is mounted.
   The leak test starts automatically.
3. When the leak test is displayed, the suction inlet on the probe or hose closes within 60 s and remains closed until the leak test is complete.
4. Release the inlet opening.
   • Leak test successful: Measurement starts.
   • Leak test failed: Inspect the accessories and the pump adapter and then repeat the leak test.
5. Observe the flushing times. For further information, see the following chapter: "Special features when measuring with the pump",
6. Remove the pump adapter.
7. After completing the measurement, make sure that the seal on the pump adapter is clean and that there are no chips of metal on the seal.
   Plug the protective cap onto the pump adapter to protect the seal from damage and being deformed.

Alarms
In the event of an alarm, corresponding displays, the optical alarm, vibration alarm as well as, if necessary, the acoustic alarm are activated (configurable). For further information, see the following chapter: "Alarm settings (factory setting)"
To acknowledge an alarm:

1. Select .

Special state
The life signal is disabled during a special state. Special states are displayed by the following visual signals:

• Yellow LED flashing – 'warm-up 1' special state
• Yellow LED continuously illuminated – general special state

No alarms are issued during a special state.
Exception: The calibration adapter is mounted in measuring mode. In this case, alarms continued to be issued as long as the measurement gas can reach the sensors.
The special state is exited by eliminating the potential error, by switching to normal measuring mode in a correctly functioning gas detector or it will switch off itself after approx. 1 minute.

Incorrect measurement!
A mounted calibration adapter blocks free gas diffusion to the sensors. Correct measured values and alarms can no longer be guaranteed.
► It is imperative to actively bump the sensors (e.g. test gas cylinder with pressure reducer, flow 0.5 L/min).

Protection alarm
The protection alarm protects the CatEx sensor.
If the measuring range is exceeded significantly at the CatEx channel (very high concentration of flammable substances), a protection alarm is triggered. This CatEx protection alarm can be acknowledged by switching the gas detector off and then on again in fresh air.
If the gas detector cannot be switched off because the A2 alarm is active and the switch-off mode in the CC-Vision is set to "Switching off not allowed during A2", remove the power pack or place the gas detector in the charging cradle and allow it to switch off automatically.
Only X-am 8000:

• This does not apply in the case of an activated full-range mode for methane and hydrogen.
• When the sensor selection wizard is used, the blocking alarm is also evaluated even when CatEx sensors are greyed out. However, the display will not show until the CatEx sensor has been activated again.

For more details, refer to the technical manual.

Pairing a gas detector with a smartphone

The Bluetooth ® function is not part of the technical suitability test.

Risk of explosion
The use of an unsuitable smartphone in an explosion-hazard area may lead to the ignition of flammable or explosive atmospheres.
► The smartphone must be suitable and approved for use in explosion-hazard areas.
For specific functions, Dräger offers apps that can be installed on a suitable smartphone or tablet. A license may be required under certain circumstances.
The gas detector can be paired with a suitable smartphone via Bluetooth in order to use the optionally available Dräger CSE Connect app. The application Dräger CSE Connect is optimised for the measurement, confined space entry measurement, and benzene/pre-tube measurement wizards.
Data transmitted via Bluetooth^® can be used for additional safety measures. However, the data does not replace primary on-site measures by the gas detector. The alarm on the gas detector is decisive. An important consideration is that a mobile network and WLAN reception are not always available or can be interrupted.
For detailed information on pairing via Bluetooth^® also refer to the instructions for use of the smartphone used.
The Bluetooth^® function may only be used in countries for which an approval exists and is not part of the certified measuring function. Contact Dräger if there are any questions about availability.
The Bluetooth^® function has not been tested for operation in the charging cradle.
Contamination of the gas detector or shielding elements (e.g. protective cover or CSE case) can reduce the Bluetooth^® range.
Failure of the Bluetooth^® communication of the gas detector is to be expected in the vicinity of strong transmitters in the range of the 2.4 GHz band.
If the Dräger CSE Connect app is used, the gas detector always has priority with respect to measurements and the gas measured values and information need to be checked on the gas detector.

Requirements:

• The Bluetooth^® module is installed in the gas detector.
• Bluetooth^® is activated on the gas detector and the smartphone.

1. Open the CSE Connect app and selectPairing.
2. Select the gas detector X-am 8000.
   If several gas detectors are within range, it may be helpful to identify the desired gas detector based on the serial number, which is printed on the gas detector. In older versions of the CSE Connect app, the gas detector can also be identified by the unique MAC address. For further information, see the following chapter: "Opening information".
3. Accept pairing on the smartphone.
   ✓ Pairing of the devices is complete.

Measurement

Special features when measuring with the pump
NOTICE
Magnetic media may be damaged!
The pump adapter and calibration adapter contain a magnet which may delete data from a magnetic stripe.
► Do not bring magnetic media (e.g. credit cards) into close proximity to the pump adapter or calibration adapter.
The pump adapter "Nona" (order no. 3720225) must be used to meet the requirements of the technical suitability test (EN 60079-29-1) for measuring the gas "Nonan" with a pump. This also achieves an optimised flushing phase.
The DrägerSensor CatEx H2 100 (order no. 3729050) should preferably be used for the regular, planned and continuous measurement of hydrogen in concentrations higher than 4 Vol%. In order to achieve the best possible measurement results, use of the Dräger "Nona" pump adapter (order no. 3720225) is recommended.
When using long hoses (from 10 m):

• Make sure the weight of the hose is supported.
• Make sure there are no kinks in the suction hose.
• The max. length of hose is 45 m (with an internal diameter of 3 to 5 mm).
• Use the dust and water separators when taking measurements with the pump (order no. 83 19 364).
• The nominal flow rate is 0.35 L/min.
• If the flow rate is < 0.3 L/min, the flow alarm with be triggered.
• Following a bump test with aggressive gases (such as biogas or chlorine), flush the pump with clean air for several minutes to extend the service life of the pump.
• Testing the response time with target gas is recommended.

The wizards are only available for X-am 8000. For DrägerSensor XXS Cl2, COCl2, O3 as well as amine and odorants, there is no wizard for clearance measurement, as these gases cannot be pumped (properly) through tubes. In addition to the gases listed above, there may also be other gases for which there are no flushing times available in the gas detector. There is no confined space entry wizard for these gases.
Flush the Dräger sampling hose or Dräger probes prior to each measurement with the gas to be measured. The flushing phase is necessary to reduce negative effects associated with the use of a sampling hose or a probe, e.g. gas transport time, memory effects, dead volume. The duration of the flushing phase depends on factors such as type and concentration of the gas or vapour to be measured as well as material, length, diameter and age of the sampling hose or probe. In addition to the flushing time, the sensor response time must be observed (refer to the instructions for use for the DrägerSensors used).
Generally, when using a sampling hose (3 mm internal diameter, new, dry, clean) with standard gasses, a typical flushing time of approx. 3 s/m is required.
Example:
The flushing time for oxygen with a 10 m hose is approx.
30 seconds. The assumed sensor response time is approx. 10 seconds in addition. Thus, the overall time before reading the gas detector is approx. 40 seconds.
A flow-rate alarm is delayed by 10 to 30 seconds depending on the length of the hose.
X-am 8000: For benzene/pre-tube measurements, the maximum hose length is 10 m.

Carrying out measurements with a pump
Requirements:

• The gas detector is equipped with a pump and is switched on.
• All installed sensors are warmed up.
• The gas detector is ready to take measurements.
• The thread port and sealing surfaces of the pump adapter need to be clean and undamaged.

1. Connect the hose (3 mm internal diameter) with the dust and water filter to the inlet spout (see figure M) of the pump adapter.
2. If necessary, connect a second hose (max. length: 2 m) to the outlet of the pump adapter (e.g. pump adapter "Nona", order no. 3720225) to direct the measured gas to an exhaust or outside.
3. Mount the pump adapter to the gas detector. Make sure that both guide pins are in the correct grooves.
   Check that the pump adapter is mounted correctly. If the pump adapter is mounted correctly, the leak test starts automatically. If the leak test does not start, the gas detector is not operational. Avoid bending the pump adapter.
   The gas detector automatically switches to pump mode as soon as the pump adapter is mounted.
   The leak test starts automatically.
   Dräger recommends carrying out the leak test directly before using the connected probe (hose probe, bar probe) to allow for the detection of any leaks in the entire intake system.
   
4. When the leak test is displayed, the suction inlet on the probe or hose closes within 60 s and remains closed until the leak test is complete.
5. Open the suction inlet.
   • Leak test successful: The measurement starts. Observe the purging times!
   • Leak test failed: Inspect the probe, hose and adapter and repeat the leak test.
6. Place the probe or the end of the hose on the sampling location.

The temperature at the measurement location may deviate from the temperature in the gas detector, which may influence the measured value display. The correct functioning of the temperature correction can only be guaranteed on the gas detector.

To stop measuring with the pump:

1. Loosen the screw on the pump adapter.
2. Remove the pump adapter.
   The pump is flushed (clearly audible noise) and the gas detector automatically switches to diffusion mode.
3. After completing the measurement, use the protective cap designed for transport and storage of the pump adapter.

Measurements with wizards

The gas detector has wizards for easily preparing the measurements and for measurement displays optimised for the measurement.
There are wizards for the following applications:

• Confined space entry: for measuring with a probe/hose, e.g. In a container
• Sensor selection: for hiding/displaying gas channels
• Leak search: for detecting gas leaks
• Benzene/pre-tube measurement: for using pre-tubes as a filter for the PID

While the wizard loads, the gas detector is in a special state.
The wizards are not supported if the gas detector does not have the required material-specific properties for the gas to be measured, or if the gas detector is not within the permissible temperature range (typically 0 to 40°C for confined spaces and benzene/pre-tube measurements).

Carrying out confined space entry measurements with the wizard

During confined space entry measurements, the duration of the measurement (in mm: ss) is displayed for a maximum of one hour in place of the time. Afterwards, the time is displayed again. The measurement duration is restarted after each flow alarm.
Requirements:

• The gas detector is switched on.
• The user is signed in with the corresponding user level.

To carry out a confined space entry measurement:

1. Sign in with the required user level, if necessary.
2. Select > Confined space in measuring mode (if configured using the Dräger CC-Vision PC software). Follow the directions of the wizard.
   The hose length or probe selection is displayed.
3. Select the hose length / probe.
   The leak test starts.
4. Confirm the successful leak test.
   The start dialog for the measurement is displayed.
5. Place the probe or the hose on the sampling location.
6. Confirm the dialog to start the measurement.
   The hose is flushed, and the remaining flushing time (flooding time) is displayed. If, during the flushing time, an alarm threshold or the permissible temperature range is exceeded, the countdown is stopped and the alarm or message is displayed.
   The displayed flushing time shows the minimum wait time required for the measurement gas to reach the sensor from the sampling location in an ideal scenario. This applies to the use of a Dräger sampling hose (fluoroelastomer, brand new, dry, clean) with an internal diameter of 3 mm and telescopic probes (max. length of 2000 mm) with a sampling hose (fluoroelastomer, brand new, dry, clean) with an internal diameter of 5 mm. Other fixtures (e.g. pre-tube) extend the minimum wait time and must also be taken into consideration. The flushing time only applies to the configured measurement gas.

The flushing times recommended by the gas detector are ascertained according to the state of technology. Dräger is not liable for their use. The user is responsible for evaluating the wait time for their application. After the wait time expires, evaluation is required to determine if the measured value is stable or if the wait time was possibly insufficient. The same applies if the countdown was stopped unexpectedly.

X-am 8000: As an option, the Dräger CC-Vision PC software can be used to define a fixed flushing time (adjustment range: 30 to 900 s) which is then used by the gas detector in the wizards. The user is responsible for determining this time and using the feature. This feature can be used, for example, when a PID sensor with custom response factors is used to use this wizard.
The measurement of other gasses or vapours than the selected measurement gas per measuring channel causes additional wait time which must also be considered in addition to the minimum wait time.
The confined space entry measurement is displayed when after the flushing time is complete.
To end the confined space entry measurement:

1. Select during the confined space entry measurement and confirm the dialog.
   A dialog for performing another confined space entry measurement is displayed.
2. Select to end the wizard.
3. Remove the pump adapter.
4. Return to normal measuring mode.

Carrying out sensor selection with the wizard

Gas channels can be temporarily hidden with the sensor selection. This is useful if certain gases are deliberately not to be measured. The alarms of the hidden gas channels are not output and no measurement data is written to the data logger.
Dräger recommends hiding the O2 channel and all other electrochemical sensors if the DrägerSensor CatEx H2 100 is to be used to measure a concentration of hydrogen exceeding 100 %LEL. When exiting the wizard or displaying the sensors again, checking the zero-point and the sensitivity is recommended if an impact on the sensors cannot be ruled out.
Channel errors and warnings, as well as possible alarms of hidden sensors are not displayed. The evaluation of the CatEx blocking alarm remains active in the background and appears when the channel is displayed again and the blocking alarm occurred while hidden.
Requirements:

• The gas detector is switched on.
• The user is signed in with the corresponding user level.

To select the sensor:

1. Sign in with the required user level, if necessary.
2. Select> Select sensors in measuring mode (if configured using the Dräger CC-Vision PC software).
3. Deselect sensors which are to be hidden.
4. Select Next to start the measurement with the wizard and the required gas channels.
   All gas channels are automatically shown again once you leave the wizard.

If an offset channel is hidden, the offsetting is interrupted.

Carrying out leak searches with the wizard

During a leak search, the duration of the measurement (in mm: ss) is displayed for a maximum of one hour in place of the time and the measured values can be displayed in the form of a bar chart (configurable with the CC-Vision PC software). Afterwards, the time is displayed again. The measurement duration is restarted after each flow alarm.
During a leak search, the Clear app. peak feature should be stored in the quick menu using the Dräger CC-Vision PC software. This feature can be used to delete the application values in the bar chart.
Because of the physical flushing times, Dräger recommends carrying out measurements with the leak search wizard without a hose/probe or with only a short hose (max. 2 m).

Requirements:

• The gas detector is equipped with a pump and is switched on.
• All installed sensors are warmed up.
• The gas detector is ready to take measurements.

To carry out a leak search:

1. Sign in with the required user level.
2. Select > Leak search in measuring mode.
3. Confirm the successful leak test to start the measurement.

The device emits tones in the "Individual measuring channel" display which increase in frequency as the gas concentration increases. If the pre-alarm threshold is reached, the gas alarm appears.

To end the leak search:

1. Select in leak search mode and confirm the dialog.
2. Remove the pump adapter.
3. Return to normal measuring mode.

Carrying out a benzene/pre-tube measurement with the wizard

Observe the instructions for use of the respective tube!
The use of a pre-tube is only possible when using the wizard. During the benzene/pre-tube measurement, the visual alarm, acoustic alarm, vibration alarm and alarm evaluation are deactivated.
A benzene/pre-tube measurement (photoionization detector) with a pre-tube (e.g. benzene pre-tube) can only be done with the benzene/pre-tube wizard.
During the benzene/pre-tube measurement, the gas to be measured and the PEAK values are visible on the display. All other sensors are not evaluated.
If the measured gas is changed while using the wizard, then the TWA and STEL evaluations present are reset.
For the user gases (VOC, VOC1... VOC9), no wizards are offered (apart from measuring) if there is no fixed flushing time saved in the gas detector. For further information see: "Measurement".

Mounting the pre-tube bracket
Fast temperature and humidity changes influence the measured signal. If temperature and humidity jumps are anticipated, Dräger recommends using a damp pre-tube for the measurement.

1. Mount the pump adapter to the gas detector. Make sure that both guide pins are in the correct grooves.
   
2. Connect the dust and water filter (3) to the short hose piece (4) on the pump adapter (5).
   
3. Mount the pre-tube bracket (2) to the dust and water filter (3).
4. Mount the hose or bar probe (1) to the pre-tube bracket (2) (max. hose length: 10 m).
5. As necessary: Use a floating probe.
6. If necessary, connect a second hose (max. length: 2 m) to the outlet of the pump adapter (e.g. pump adapter "Nona", order no. 3720225) to direct the measured gas to an exhaust or outside.

Use an adapter piece for varying hose diameters if necessary (minimum internal diameter: 3 mm).

Carrying out the measurement
A new pre-tube must be used for every single measurement or calibration with pre-tube.
Requirements:

• The gas detector is switched on.
• The user is signed in with the corresponding user level.

Activating full-range mode

Full-range mode is not part of the technical suitability test.

Risk of explosion!
Only for CatEx125 PR and CatEx125 PR Gas: The full-range mode only applies for methane in the air.
Only for CatEx H2 100: The full-range mode only applies for hydrogen in the air.
Any other gas composition impacts the measured signal and may cause an incorrect display.
► Only use the full-range mode to measure methane and hydrogen in the air.
The full-range mode can only be activated for the sensors
DrägerSensor CatEx 125 PR (order number 68 12 950) and CatEx 125 PR Gas (order number 68 13 080) with the measured gas methane and for DrägerSensor CatEx H2 100 with the measured gas hydrogen.
When full-range mode is activated, there is an automatic switch to the Vol% range if measured values exceed 100 %LEL.
When the "No measured values in Vol% range" feature is activated, the full-range mode in %LEL will continue to be shown instead of the measured values in the Vol% range.
When the values return to the <100 %LEL methane or hydrogen range, the measured value display alternates with the transitional phase indicator (circle arrow).
Prerequisite:

• The %LEL (heat of reaction) and Vol% (thermal conduction) measuring ranges are calibrated.

1. Activate the full-range mode with the Dräger CC-Vision PC software.
2. If necessary, activate the "No measured values in Vol% range" feature with the Dräger CC-Vision PC software.

Hydrogen (H2) added signal (for IR Ex)

The H2 added signal can be adjusted using the Dräger CCVision PC software.
Requirements:

• At least one DrägerSensor XXS H2 HC (68 12 025) is activated. H2 is set as the measurement gas.
• An Ex channel on the DrägerSensor DUAL IR Ex/CO2 (68 11 960) or DrägerSensor IR Ex (68 12 180) is activated.
• Both channels are set to the unit %LEL/%LEL/%LIE.
• The H2 added signal is only possible with a DrägerSensor XXS H2 HC and an IR Ex channel.

When the H2 added signal is activated, the LEL gas concentrations of both selected sensors are added together and the result is shown in the display in the place of the IR Ex display.
An activated H2 added signal is displayed with a + next to the gas name of the IR Ex sensor in the display.
Previously set alarm thresholds are maintained in order to ensure that in the presence of hydrogen (H2) the alarm of the IR Ex Channel is triggered earlier if required.

1. Tested without the pump or calibration adapter.

Operating time in normal conditions (diffusion mode)¹⁾:

With IR and 3 EC sensors	Typically 22 h
With CatEx, PID and 3 EC sensors	Typically 17 h
With CatEx, IR and 3 EC sensors	Typically 12 h
With IR, PID and 3 EC sensors	Typically 16 h
With PID	Typically 42 h

1. The nominal operating time of the gas detector at an ambient temperature of 20 to 25°C, 1013 mbar, alarms less than 1% of the time, power-save mode display activated. The actual operating time varies depending on the ambient temperature and pressure and battery and alarm conditions.

In pump mode: If the gas detector is used permanently in pump mode, the operating time is reduced by approx. 2 h.

Use in areas subject to explosion hazards

To reduce the risk of ignition of a flammable or explosive atmosphere, strictly observe the following warnings:

Use in areas subject to explosion hazards
Devices or components for use in explosion-hazard areas which have been tested and approved according to national, European or international explosion protection regulations may only be used under the conditions specified in the approval and with consideration of the relevant legal regulations. The devices or components may not be modified in any manner. The use of faulty or incomplete parts is forbidden. The appropriate regulations must be observed at all times when carrying out repairs on these devices or components.
X-am 8000: Increased hydrogen concentrations within the measuring range of the DrägerSensor XXS H2 HC may result in false alarms due to the additive effect on DrägerSensors XXS H2S and XXS CO, XXS H2S-LC and XXS CO-LC as well as due to the negative effect on DrägerSensor XXS O2 and XXS O2 PR.
X-am 8000: Increased hydrogen concentrations within the measuring range of the DrägerSensor CatEx H2 100 may briefly influence the Dräger sensors XXS H2, XXS H2 HC, XXS H2S, XXS O2 and lead to incorrect measured value displays and false alarms. Other electrochemical sensors from Dräger may be impaired in the longer term, which is why they must not be used together with a DrägerSensor CatEx H2 100.

Oxygen enriched atmospheres
Explosion protection is not ensured in oxygen enriched atmospheres (>21 Vol% O2).
Remove the device from the explosion-hazard area.

Oxygen deficient atmospheres
The CatEx sensor may display false readings and incorrect measured values when used for measurements in an oxygen deficient atmosphere (<12 Vol% O2). In this case the CatEx sensor cannot provide a reliable measurement.
► The CatEx sensor is intended for the measurement of flammable gases and vapours mixed with air (i.e. O2 content ≈ 21 Vol%). If the O2 content falls below 12 Vol% and an operational O2 sensor is available in the gas detector, a channel error is triggered on the CatEx channel due to oxygen deficiency. This does not apply in thermal conduction mode in the measuring range up to 100 Vol%.
A DrägerSensor CatEx125 PR or CatEx125 PR Gas should preferably be operated with an active DrägerSensor XXS O2 or O2 PR so that oxygen deficiency can be evaluated by the gas detector.
► Remove the gas detector from the area and discontinue measurement.

Incorrect calibration

An incorrect calibration leads to incorrect measured values.
► CSA requirement (Canadian Standard Association): The sensitivity must be checked daily before first using the device, with a known concentration of the gas to be measured that corresponds to 25 to 50% of the final concentration. The accuracy must be 0 to +20% of the actual value. The accuracy can be corrected by calibration.

RFID tag (optional)
► The RFID tag must not be read out in explosion-hazard areas.

NOTICE
Damage to the CatEx sensor!
Fractions of catalytic poisons in the measuring gas (e.g. volatile silicon, sulphur, heavy metal compounds or halogenated hydrocarbon) can damage the Cat Ex sensor.
► If the CatEx sensor can no longer be calibrated to the target concentration, replace the sensor.

DrägerSensor CatEx 125 PR (6812950) and CatEx 125 PR Gas (6813080)
► For this gas detector, only use sensors with serial numbers > ARLB XXXX (starting with date of manufacture in February 2018). These sensors are certified for use in zone 0, T4.

When using the PID sensor
► To ensure safe operation, the gas detector must not be switched on at temperatures below -10°C when using the PID sensor (6813475/6813500).
