is too high
•
Purge air supply has failed or is
too weak
• The gas pressure in the gas duct
is too high
• Purge air supply has failed or is
too weak
• Probe gap alignment incorrect.
The sample gas flow must not be
pressed into the purge air open‐
ings

Possible causes
•
The gas pressure in the gas duct
is too high
• Purge air supply has failed or is
too weak
• Purge air supply has failed or is
too weak
Possible causes
Unsuitable materials
Possible causes
• Measured value is "uncertain" (e.g.
calibration range exceeded).
TROUBLESHOOTING
Action
see "Sample gas penetrating", page
see "Sample gas penetrating", page
Check installation.
►
Check sample gas conditions (temperature,
►
moisture, concentration etc.).
Check start-up.
►
Check status/error messages.
►
Check:
►
– Were correct test gases used?
– Are setpoint values correct?
If the answer to both questions is "Yes", con‐
►
tact SICK Service to have a calibration per‐
formed.
Report to manufacturer's Technical Service or
►
trained skilled persons.
Action
Check project planning.
►
Check purge air supply.
►
Provide redundant purge air supply.
►
Increase purge air supply.
►
Action
Replace measuring probe.
►
Remedy
Check the calibration range.
