Check of parameters
To ensure that the values were correctly transferred to the gas detection
instrument:
● Button select data from X-am 1/2/5x00 to CC Vision.
Check parameters.
First commissioning
Before using the instrument for the first time, insert the batteries supplied or
a charged T4 NiMH power pack T4 (HBT 0000 type, order no. 83 18 704) /
T4 HC (HBT 0100 type, order no. 83 22 244) (refer to chapter "Replacing the
batteries" on Page 21). The Dräger X-am 5000 is ready for operation.
Operation
Switching on the instrument
 Press and hold the [OK] key for approx. 3 seconds until the countdown
» 3 . 2 . 1 « shown on the display has elapsed.
– All the display segments, including the visual, audible and vibration alarms,
are activated for a short time.
– The software version is displayed.
– The instrument performs a self test.
– The next sensor to be calibrated is displayed, along with the remaining days
to the next calibration, 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. H
2
S or CO) are displayed consecutively.
– During the running-in period of the sensors, the respective displays of the
measured value flash and the special symbol » « (for warning) is displayed.
No alarms are issued during the warm-up period of the sensors.
 Press the [OK] to cancel the display of the activation sequence.
Switching off the instrument
 Press and hold the [OK] and [ + ] key simultaneously for approx. 3 seconds
WARNING
Use only battery types ABT 01xx, 00xx HBT or HBT 01xx. See identification
on the battery for approved batteries and the corresponding temperature
class.
Replacing components may impair the intrinsic safety.
1) Only when activated in the instrument configuration. Delivery condition: not activated.
until the countdown » 3 . 2 . 1 « shown on the display has elapsed.
– Before the instrument is switched off, the visual, audible and vibration alarms
are activated for a short time.
Before entering the workplace
 Switch on the instrument. The current measured values are shown in the
display.
– Observe any warning » « fault messages » « .
● Check that the gas inlet opening on the instrument is not covered
or dirty.
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.
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.
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 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, the sensor must be replaced.
● In case of measurements in oxygen-deficient atmosphere (<8 vol. % O
2
)
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. % O
2
), the explosion
protection cannot be guaranteed; remove instrument from the Ex area.
● High values outside the display area indicate an explosive concentration
where applicable.
