Switching Off The Instrument; Before Entering The Workplace - Dräger X-am 5000 Instrucciones De Uso

– 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 (to view the warnings, see
the technical manual).
 Press the [OK] key to cancel the display of the activation sequence.

Switching off the instrument

 Press and hold the [OK] and [ + ] keys at the same time 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

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 CatEx sensor is intended for measurements of flammable gases and vapours
mixed with air (i.e. O content ≈ 21 vol.%). Incorrect measured values may be

displayed in the case of oxygen deficient or oxygen enriched environments.
If the gas detector is used for offshore applications, a distance of 5 m to a
compass must be complied with.
 Switch on the instrument. The current measured values are shown in the display.
– 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.

 Check that the gas inlet opening on the instrument is not covered or dirty.
Explosion hazard! To reduce the risk of ignition of a flammable or explosive
atmosphere, strictly adhere to the following warning statements:
Fractions of catalytic poisons in the measuring gas (e.g. volatile silicium,

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 (<12 vol.-% O
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
protection cannot be guaranteed; remove instrument from the explosion-
hazard area.
 High off-scale readings may indicate an explosive concentration.
