8 Trouble Shooting
Troubleshooting should always be carried out by skilled personnel. The
G36p Oxygen Analyzer is connected to hazardous electric voltages, which
can cause personal injury or mechanical damage if not handled correctly
and in accordance with normal safety regulations.
Trouble Possible Cause →Action
No display at all → Check the circuit breaker
→ Check the power supply – make sure that the power supply is
the correct voltage
→Check the ON/OFF switch at the back of the analyzer – make
sure it is ON
→ Check the fuse on the back of the analyzer
No display despite
power supply and
fuse is found OK
The analyzer is defect → r eboot, repair, or exchange the analyzer
Display only
indication 0.0
No signal from sensor → check the connection both at the ana-
lyzer and sensor. Then wait several minutes and re-plug the sen-
sor or restart the analyzer.
Check the sensor temperature in Information Menu, see sec-
tion 4.3.
If the sensor temperature could not reach its operating tempera-
ture before it starts working, the sensor’s diagnostic status will
show OK, but the display only indicates 0.0 → check if the sam-
ple flow is too high.
Try taking the sensor out of the sensor house and let it hang in the
ambient air to see if the sensor temperature can reach its operating
condition.
Incorrect indication
of oxygen level
→ Try to recalibrate the analyzer
→ If normal calibration is not working, try artificial calibration
see section 6.2.
→ Check the sensor’s diagnostic status and temperature in Infor-
mation Menu, see section 4.3. Check the sensor connection or re-
place the sensor if it is defect
Incorrect remote There might be a mismatch in the output range of the analyzer
