8 Fault – Cause – Remedy
Fault / message
Not possible to switch on the instrument
The instrument cannot be charged.
Notice: "Instrument failure" or "Sensor has bad contact"
Instrument displays potentially individually incomprehensible characters
Instrument turns on continually
The instrument is defective
Flow too low!
No valid span calibration
Cause
Power pack is fully discharged.
Temperature too high or too low
Power pack is not connected correctly or bad contact in the power-pack connector.
Wrong language selected
Remedy
Charge the power pack.
Note: In this case, the instrument display initially remains blank.
Observe temperature range.
Reconnect the power pack and secure it with the screws.

Electronic fault (Watchdog)
An internal fault has been detected.
#2: Instrument fault
#129: Electronic fault
#130: Fault when switching on the flow sensor
Hose is blocked
Switch the instrument off then on again, or remove and reconnect the power pack. If the fault is still displayed, contact DrägerService.
Switch the instrument off then on again, or remove and reconnect the power pack. If the fault is still displayed, contact DrägerService.
Inspect the hose for kinks and blockages.
If necessary, remove the pump adapter and inspect the membrane in the sensor grille for dirt and drops of water.
Ensure that the hose is not kinked or submerged during use.
#9 Pump faulty Replace the pump.
#107: Calibration was executed without test gas Repeat calibration with test gas.

Date and time not valid
Data logger 90 % full / data logger full
Sensor warming up
Cause
#104: Long-term drift of the sensor.
Remedy
Carry out fresh air calibration / zero-point calibration.
The instrument has found a fault in the IR sensor.
#118: IR sensor faulty.
Switch the instrument off then on again,
remove and reconnect the power pack.
If necessary, replace the IR sensor. If the fault is still displayed, contact DrägerService.
There is no valid zero-point calibration.
Repeat zero-point calibration with a suitable zero gas.
#106: Zero-point calibration was not completed successfully (e.g. no suitable zero gas used/
CAT sensor was exposed to nitrogen)
Carry out zero-point calibration with a suitable zero gas.
#123: Fault during calibration Repeat the calibration procedure or disconnect and reconnect the power pack. If the fault still exists, change the sensor or inform
DrägerService.
The instrument has detected a fault in the sensor.
#108: Inconsistent sensor data.
#133: Measuring signal is outside of the permitted range.
Switch the device off and on again. If the fault
still displayed on the instrument, contact
DrägerService.
The CatEx sensor needs oxygen for correct operation. If insufficient oxygen is available, the sensor cannot measure correctly.
Use an IR-Ex sensor in atmospheres with O

The warming-up time of the sensors may vary, depending on the ambient conditions
Wait until the sensor has warmed up.

Fault – Cause – Remedy
Fault / message
Increased measuring failure
Sensor near end of life
Sensor not supported
Cause
The measuring error is higher during the warming-up phase. Calibration cannot yet be executed.
Remedy
Info Mode provides further details.
Measurements can still be carried out under these conditions.
The sensor no longer has sufficient reserves for calibration
#100: The sensor is not supported by the instrument.
The sensor cannot be used.
For details, contact DrägerService.
Config error, Channelinit required
No sensor or bad contact No sensor in the active sensor slot Plug in a sensor or deactivate the channel.
#100: The sensor has been removed or there is a bad sensor in the sensor connector
Switch the instrument off and on again.
If necessary, remove the sensor and insert
Temperature out of range, incr. meas. failure The sensor was/is too cold
Temperature out of range, incr. meas. failure The sensor was/is too warm
No valid TC span calibration
Channel error
The CatEx sensor has been calibrated in the
Vol% range (>100 LEL) with a CH
4 concentration which was too low. (e.g. with
2 Vol.-% CH
4
)
An error has been detected in the measuring channel.
#109: An error occurred during loading of the sensor data
The sensor must be calibrated or adjusted.
The sensor must be calibrated or adjusted.
Repeat calibration in the TC range
(>100
50
LEL) with a concentration of about
Vol.-%.
Switch the device off and on again. If necessary, remove and reconnect the power pack. If the fault is still displayed on the instrument, contact
DrägerService.

Checksum error: instrument init.
Internal com error with subsystem 3
Invalid fresh air calibration

Cause Remedy
Note: All settings made with the menu will reset to the factory settings.
Carry out instrument initialisation, switch the instrument off and on again or remove and reconnect the power pack.
The data connection to the power pack is opencircuit.
(It may be that the screws are not tightened correctly)
Remove the power pack and connect it correctly.

Repeat fresh-air calibration in clean air.
CO content too high)

Fault – Cause – Remedy
Fault / message
High IR signal
Sensitivity low. Please check lamp
Perform bump test
Cause
The instrument has found a fault in the IR sensor.
#127: High IR signal
Switch the device off and on again.
If the fault is still displayed on the instrument, contact DrägerService.
#132: Span falls short of warning setpoint
Remedy
# 137: Bump test failed
Clean the lamp on the PID sensor, see sensor data sheet. If the device continues to display this error, replace the lamp of the PID sensor, see sensor data sheet.
A new bump test is required each time the
Automatic bump test does not start exited.
Repeat bump test, ensure that gas is continuously supplied during the test. If required, re-adjust the sensors.
Rectify the channel or instrument fault and repeat the bump test.
Configure the Dräger X-am 7000.
Dräger X-am 7000 were not configured according to Dräger CC Vision
There is no activated printer with correctly positioned IR interface in front of theBumpTest
Station
Switch on the printer and position the IR interface of the printer in front of the fiberoptic cable of the
BumpTest Station.
The manual Bumptest cannot be started via the "Quick Menu"
One of the channels activated for the Bumptest is in WarmUp or Error mode or an instrument fault has occurred
Wait until the WarmUp time has elapsed, rectify the fault and restart the Bumptest.
