Sample gas penetrating
Possible causes
Information
Power supply not connected.
▸
Check power cable and connections.
Main power supply has failed.
▸
Check power supply (e.g. socket, external disconnecting device).
Internal operating temperatures
not correct.
▸
Check whether error messages exist.

Possible errors
Possible causes
Remedy
Leakages (on GPP probe).
---
▸
Have the GPP probe checked by
SICK Customer Service.
Sample gas penetrated the area
before the SR-unit.
●
Gas pressure in gas duct too
high.
●
Purge air unit has failed or is too
weak.
▸
see “Sample gas penetrating”,
page 55
.
For GPP probe: Temperature dropped
below dewpoint.
---
▸
Check project planning.
Sample gas penetrates the purge air
compartment.
●
Gas pressure in gas duct too
high.
●
Purge air unit has failed or is too
weak.
▸
see “Sample gas penetrating”,
page 55
.
●
Probe gap alignment incorrect.
Sample gas flow must not
pressed into the purge air
openings.
▸
Check installation.
Sample gas conditions do not match,
or no longer match, project planning.
●
Plant condition has changed
▸
Check sample gas conditions
(temperature, moisture,
concentration etc.).
GM32 not ready for operation.
---
▸
Check start-up
▸
Check status/error messages.
GM32 calibration is not correct.
---
Check:
Were correct test gases used?
Are setpoint values correct?
If this does not help: Carry out a
calibration (please contact SICK
Service).
Analyzer is contaminated.
---
Report to manufacturer's Technical
Service or trained skilled persons.
