Monitoring Measuring Mode; Alarms; Special State - Dräger X-am 8000 Gebrauchsanweisung

en Operation
As an option, the Dräger CC-Vision PC software can be
used for adjustment so that any impact detected leads to a
channel error for all sensors. These channel errors are
deleted after calibration. If the sensor should be irreparably
damaged, then this could result in a calibration error.
®
Only using Bluetooth or API applications is insufficient for
raising the alarm in safety-critical applications. Raising the
alarm on the gas detector is decisive.
Contact Dräger for a description of the API interface.
The use of Bluetooth® function and the API application are
not part of the technical suitability test.
CAUTION
High readings outside of the LEL display range or a blocking
alarm may indicate an explosive concentration.
If the concentrations of combustible materials are too high,
this may be the result of a lack of O
The IP degrees of protection do not indicate whether the
device detects a gas during or after it was exposed to it.
Check the calibration and functional integrity of the device in
the event of dust deposits and contact with water through
submersion or a water jet.
In the event of overgassing beyond the sensor's measuring
range, the zero-point and the sensitivity must be checked and,
if necessary, a calibration must be performed.
The PEAK, STEL and TWA evaluations are interrupted if the
menu is selected or in the case of the special state of a pump
leak test. For a flawless calculation of the evaluations, only
operate the gas detector in normal measuring mode.
Selecting the quick menu has no influence on the PEAK,
STEL and TWA evaluations.
A distance of at least 5 m to compasses must be complied
with if the gas detector is used for offshore applications.

4.7.1 Monitoring measuring mode

In normal measuring mode, the measured values are
displayed for every measurement gas (see Graphic E on the
fold-out page). The operation signal sounds at regular interval
(configurable), and the green LED pulses (e.g. visual
operation signal or D-light feature).
If a measuring range is exceeded or not reached, the
respective symbol is displayed instead of the measured value.
For further information, see the following chapter: "Symbol
explanations", page 34
If, in measuring mode, a event (e.g. an alarm) occurs, the
respective symbol is displayed in the status bar (after the
event is acknowledged, if necessary).
4.7.1.1 Displaying the measuring channel
To display an individual measuring channel:
1. Select in measuring mode.
2. Use ▲ or ▼ to view the individual measuring channels.
3. Select to navigate to the measuring channel overview.

4.7.1.2 Opening the event report
If the gas detector is switched off and then on again, the
event report is deleted.
The following events are counted and displayed: A1/A2,
STEL, shocks, incorrect password entries.
To open the event report:
1. Select > Info > Device information in measuring
mode.
2. Use ▲ or ▼ to scroll through the individual pages until the
event report.
The symbol indicates a failed sign-on only after 5
attempts.
4.7.1.3 Activating the pump
To activate the pump in (normal) measuring mode:
1. Place, align and tighten the pump adapter on the thread
port on the top cover. Check that the pump adapter is
mounted correctly. Avoid bending the pump adapter. The
gas detector automatically switches to pump mode as
soon as the pump adapter is mounted.
 The leak test starts automatically.
2. When the leak test is displayed, the suction inlet on the
probe or hose closes within 60 s and remains closed until
the leak test is complete.
3. Release the inlet opening.
● Leak test successful: Measurement starts.
● Leak test failed: Inspect the accessories and the pump
adapter and then repeat the leak test.
4. Observe the flushing times. For further information, see
the following chapter: "Special features when measuring
with the pump", page 40

4.7.2 Alarms

In the event of an alarm, corresponding displays, the optical
alarm, vibration alarm as well as, if necessary, the acoustic
alarm are activated (configurable). For further information,
see the following chapter: "Alarm settings (factory
setting)", page 52
To acknowledge an alarm:
1. Select .

4.7.3 Special state

The operation signal is deactivated during a special state.
Special states are displayed by the following visual signals:
– Yellow LED flashing – 'warm-up 1' special state
– Yellow LED continuously illuminated – general special
state
No alarms are issued during a special state.
Exception: The calibration adapter is mounted in measuring
mode. In this case, alarms continued to be issued as long as
the measurement gas can reach the sensors.
