During Operation; Identifying Alarms - Dräger X-am 5600 Gebrauchsanweisung

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 flammable or explosive atmospheres
igniting, it is essential that the warning notices below are observed:
 In an oxygen enriched atmosphere (>21 Vol.-% O
tion cannot be guaranteed; remove instrument from the Ex area.
 High values outside the display area indicate an explosive concentration
where applicable.

During operation

– During operation, the measured values for every measured gas are
displayed.
– If a measuring range is exceeded or not reached,the following displays are
shown instead of the measured value display:
» « (measuring range exceeded) or
» «
(measuring range not reached).
– If the concentrations of combustible materials are too high, this may be the
result of a lack of O .
2
– In the event of an alarm, the corresponding displays, including the visual,
audible and vibration alarms, are activated. See section "Identifying
alarms".
– After the measuring range of the EC measuring channels has been
exceeded temporarily (up to one hour), checking the measuring channels is
not necessary.
Special states in which there is no measuring operation (quick menu,
calibration menu, warm-up of sensors, password input) are indicated by a
visual signal (slow flashing of the alarm LED
WARNING
), the explosion protec-

NOTICE
).
When using an IR Sensor in the Dräger X-am 5600, the zero point and
sensitivity must be adjusted after an impact load that causes a display other
than zero for the IR sensor when the instrument is at fresh air.

Identifying alarms

An alarm is displayed visually, audibly and through vibration in a specific pattern.
Concentration pre-alarm A1
The alarm is indicated by an intermittent alarm
message:
Display » A1 « and measured value alternating:
not for O !
2
The pre-alarm A1 is not self-latching and stops when the concentration has
dropped below the alarm setpoint A1.
In the case of A1 a single tone is audible and the alarm LED flashes.
In the case of A2, a double tone is audible and the alarm LED flashes twice.
Acknowledging the pre-alarm:
 Press the [ OK ] key, only the audible alarm and the vibration alarm are
switched off.
Concentration main alarm A2
The alarm is indicated by an intermittent alarm
message:
Display » A2 « and measured value alternating:
for O : A1 = lack of oxygen
2
A2 = excess oxygen
Danger to life! Leave the area immediately.
A main alarm is self-latching and cannot be acknowledged or cancelled.
After leaving the area, if the concentration is less than the alarm threshold A2:
Press the [ OK ] key, the alarm messages are switched off.
