Cause
An invalid unit has been selected for this sensor.
There is no sensor in the active sensor slot.
#100: The sensor has been removed or there is a
bad contact in the sensor connector.
The sensor was/is too cold.
The sensor was/is too warm.
The CatEx sensor has been calibrated in the
Vol% range (>100% LEL) with a CH
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 instrument has detected an internal error.
#1:
The data connection to the power pack is open-
circuit (the screws are perhaps not tightened
correctly).
The air in which fresh-air calibration was carried
out was not free of contamination
(e.g. CO content too high).
Nitrogen was used for fresh-air calibration.
The results of mixed-gas calibration were invalid
(possibly a sensor at the end of its life).
Mixed-gas calibration for O sensor was carried
2
out with a mixed gas which did not contain O
Remedy
Carry out channel initialisation (see page 56).
Plug in a sensor or deactivate the channel.
Switch the instrument off and on again, and /or
remove sensor and insert again, page 86.
The sensor must be calibrated or adjusted.
The sensor must be calibrated or adjusted.
Repeat calibration in the TC range (>100% LEL)
with a concentration of about 50 Vol.-%.
4
Switch the instrument off and then on again, or
remove and reconnect the power pack. If the fault
is still displayed, contact DrägerService.
Carry out basic initialisation (see page 41).
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.
Remove the power pack and connect it correctly.
Repeat fresh-air calibration in clean air.
Repeat fresh-air calibration in clean air.
Inspect the sensors and replace any faulty ones.
Use a suitable test gas and compare the
. concentration information on the test gas
2
cylinder with the concentration specified for the
instrument.
