Dräger X-am 5600 Instrucciones De Uso página 21

Charge instrument with NiMH power pack
T4 (Type HBT 0000) / T4 HC (Type HBT 0100)
Explosion hazard! To reduce the risk of ignition of a flammable or explosive
atmosphere, strictly adhere to the following warning statements:
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.
Only charge NiMH power packs T4 (type HBT 0000) or T4 HC (type HBT 0100)
with the appropriate Dräger charger. Ambient temperature during charging:
0 to +40 °C.
Even if the instrument is not used, we recommend that you store the instrument
in the charger!
 Insert the switched off instrument into the charger.
– Display LED on the charger:
To maintain the lifetime of the batteries, charging is temperature controlled and
only performed in a temperature range of 5 to 35
range is left, the charging process is automatically interrupted and automatically
continued after the temperature range has been reached again. The charging
time is typically 4 hours. A new NiMH power pack reaches its full capacity after
three complete charge / discharge 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.
Carrying out manual bump test
In the case of a manual function test the effect of the H
taken into account accordingly.
A potentially activated H offsetting is automatically temporarily deactivated

The automatic functional test with the Bump Test Station is described in the
instructions for use for the bump test station and in the Technical Manual.
 Prepare a test gas cylinder, the volume flow must be 0.5 l/min and the gas
concentration must be higher than the alarm threshold concentration to be
tested.
 Connect the test gas cylinder to the calibration cradle (order no. 83 18 752).
Risk to health! Never inhale the test gas.
Observe the hazard warnings of the relevant Safety Data Sheets.

Switch on the instrument and insert it into the calibration cradle – press
downwards until it engages.
 Open the test gas cylinder valve to let test gas flow over the sensors.
 Wait until the instrument displays the test gas concentration with sufficient
tolerance, e.g.
IR Ex: ±20 % of the test gas concentration
IR CO : ±20 % of the test gas concentration
2
1)
O : ±0.6 vol. %
2
TOX: ±20 % of the test gas concentration
– If the alarm thresholds are exceeded, the instrument displays the gas
concentration in alternation with » A1 « oder » A2 « depending on the test
gas concentration.
 Close the test gas cylinder valve and remove the instrument from the
calibration cradle.
If the displays are outside of the above-mentioned ranges:
 Have the instrument adjusted by the service personnel.
To check the measured value response times, apply t90 test gas to the X-am
via the calibration cradle. Check the results in accordance with the information
in the table in the enclosed supplementary documentation (order no.
90 33 890) until 90 % of the end display is reached.
After the bump test (menu), the display shows a printer icon even if there is no
printer connected to the bump test station.
1) Upon application of the Dräger mixed gas (order no. 68 11 132) the displays should be within
this range.
