Portable gas detection instrument for the continuous monitoring of the concentration of several gases in the ambient air within the working area and in explosion-hazard areas.
Independent measurement of up to 4 gases, in accordance with the installed Dräger sensors.
Copies of the name plate and the declaration of conformity are provided in the enclosed supplementary documentation (order no. 90 33 890).
Do not stick anything on the name plate on the gas detector. The technical approvals are valid for the X-am 2500 gas detection instrument and the calibration cradle. The explosionprotection approvals are only valid for the X-am 2500 gas detection instrument; the calibration cradle must not be used in the Ex zone.
The BVS 10 ATEX E 080 X technical suitability test is based on the calibration with the target gas.

Operation
Note the following for CSA (Canadian Standards Association) applications:
For the CSA approval only the functions of the device component that is used to measure flammable gases are tested. The device is not approved by CSA for use in mining.
WARNING
! Before daily use, test the sensitivity with a known concentration of the applicable gas corresponding to 25 to 50 % of the maximum concentration. The accuracy must be within a range of 0 to +20 % of the actual value. Perform a calibration to correct the accuracy if necessary.
The charging time is typically 4 hours.
A new NiMH power pack reaches its full capacity after three complete charging/discharging cycles.
Never store the instrument for extended periods without
being connected to a power source (maximum of 2 months) because the internal buffer battery will drain.
Charging with the charging module adapter and the power supply unit 83 21 849 or 83 21 850
A maximum of 5 instruments in charging modules (order no. 83 18 639) can be charged at the same time on the charging module adapter (order no. 83 25 736) in connection with the power supply unit (order no. 83 21 849). Up to 20 instruments can be charged at the same time with the power supply unit 83 21 850.
Before attaching the charging modules to the charging module adapter, disconnect the power supply unit from the mains supply!
WARNING
! To reduce the risk of ignition of a flammable or explosive atmosphere, strictly adhere to the following warning statements: Only use power pack types ABT 01xx, HBT 00xx or HBT 01xx. See the marking on the rechargeable battery for permitted rechargeable batteries and the corresponding temperature class.
Substitution of components may impair intrinsic safety.
Before using the instrument for the first time, insert a charged NiMH T4 power pack or batteries approved by Dräger see section 3.1.2 on page 7.
The instrument is now ready for operation.

WARNING |
|
Explosion hazard! To reduce the risk of flammable or |
||
|
||
|
explosive atmospheres igniting, it is essential that the |
|
|
warning notices below are observed: |
|
|
Do not charge underground or in explosion hazard areas! |
The chargers are not designed in accordance with the regulations for fire damp and explosion protection.
Charge the NiMH power pack T4 (type HBT 0000) or T4 HC (type HBT 0100) with the associated Dräger charger. Charge NiMH single cells for ABT 0100 battery holder in accordance with the manufacturer's specifications. Ambient temperature during the charging process: 0 to +40 °C.
|
|
NOTICE |
|
i |
|
|
Even if the instrument is not used, Dräger |
|
|
|
recommends storing the instrument in the charging |
|
|
cradle (chargingmodule X-am 1/2/5000, order no. |
|
|
83 18 639). |
|
|
|
To maintain the lifetime of the batteries, charging is temperature controlled and only performed in a temperature range of 5 to 35 °C. When outside this temperature range, the charging automatically interrupted and automatically recommenced after the temperature range has been reached again.
! CAUTION
Always connect or disconnect the charging modules individually and never in groups in order to prevent the charging module adapter from becoming damaged. Even during transportation, always handle the power supply unit and the charging modules individually and without instruments inserted.

The sensor that is up next for calibration/adjustment is
displayed with the remaining days until the next calibration/adjustment e. g. » Ex %LEL CAL 20 «.
The time until the bump test interval elapses is displayed in days, e.g. » bt 123 «.
All A1 and A2 alarm thresholds and » « (TWA)1) and » « (STEL)1 for all toxic gases (e. g. H2S or CO) are displayed consecutively.
During the sensor warm-up phase:
The display for the measured value flashes The special symbol » « is displayed.
No alarms are issued during the warm-up phase.
The red LEDs flash.
The gas detector is ready to measure when the measured values no longer flash and the red LEDs are
no longer illuminated. The special symbol » « may continue to be displayed if corresponding warnings (e.g. not yet ready for calibration) are active.
2.Press the [OK] key to cancel the display of the activation sequence.
1)Only when activated in the instrument configuration. Delivery condition: not activated.
Press and hold the [OK] key and [ + ] key simultaneously until the countdown » 3 . 2 . 1 « shown on the display has elapsed.
When the instrument is switched off, the visual, audible and vibration alarms are activated for a short time in order to protect against inadvertent switch off.
WARNING
! Before any measurements relevant to safety are made, check the adjustment with a bump test, adjust if necessary and check all alarm elements. If national regulations apply, a bump test must be performed according to the national regulations. Faulty adjustment may result in incorrect measuring results, with possible serious consequences.

CAUTION |
||
The CatEx sensor is intended for measurements of |
|||
|
|
||
|
|
flammable gases and vapours mixed with air (i.e. O2 |
|
|
|
content ≈ 21 vol.%). Incorrect measured values may |
|
|
|
be displayed in the case of oxygen deficient or oxygen |
|
|
|
enriched environments. |
|
|
|
|
|
|
|
NOTICE |
|
|
i |
||
|
If the gas detector is used for offshore applications, a |
||
|
|
distance of 5 m to a compass must be complied with. |
|
|
|
|
1.Switch on the instrument. The current measured values are shown in the display.
2.Observe any warning » « or fault messages » «.
The instrument can be operated normally. If the warning message does not disappear automatically during operation, the instrument must be serviced after the end of use.
The instrument is not ready to measure and requires maintenance.
3.Check that the gas inlet opening on the instrument is not covered.

WARNING |
|
Explosion hazard! To reduce the risk of flammable or |
||
|
||
|
explosive atmospheres igniting, it is essential that the |
|
|
warning notices below are observed: |
Fractions of catalytic poisons in the measuring gas (e.g. volatile silicone, sulphur, heavy metal compounds or halogenated hydrocarbon) can damage the CatEx sensor. If the CatEx sensor can no longer be calibrated to the target concentration, the sensor must be replaced.
In case of measurements in an oxygen-deficient
atmosphere (<12 Vol.-% O2) the CatEx sensor may show incorrect displays; in this case, a reliable measurement with a CatEx sensor is not possible.
In an oxygen enriched atmosphere (>21 vol. %
O2), the explosion protection cannot be guaranteed; remove instrument from the Ex area.
High values outside the display area indicate an explosive concentration where applicable.

2)Different settings can be selected to meet customer requirements on delivery. The current setting can be checked and changed with the Dräger CC Vision software.
3)A periodic short flashing indicates the operating capacity of the instrument. If there is no operating signal, correct operation cannot be guaranteed.
4)STEL: average value of an exposure over a short period, generally 15 minutes.
5)Interpretation only if the sensor is designed for this.
6)TWA: shift averages are workplace limit values for generally eight hours per day of exposure for five days a week during a working life.
7)Latching and acknowledgement of alarms A1 and A2 can be configured with the Dräger CC Vision PC software.
Changing the configuration: see “Replacing the sensors” on page 20.
