16.0 TROUBLESHOOTING
16.1 Troubleshooting guide
SYMPTOM PROBABLE CAUSES AND REMEDIES
The instrument does not work at all. When the On/Off
pushbutton is pressed the instrument does not come
on.
a. Keep the On/Off key depressed for at least 2
seconds.
b. The battery is low; connect the battery charger to
the instrument.
c. The battery pack is not connected to the instrument;
remove the cover from the battery compartment and
connect the connector of the battery pack to the outlet
on the printed circuit board.
d. The instrument is faulty: send it to service centre.
The battery symbol is empty on the inside. The batteries are low. The instrument will remain on for
a couple of minutes after which it will switch off;
connect the battery charger.
After auto-calibration is complete the sensor
diagnostics screen appears and gives an error for one
or more sensors.
a. Auto-calibration took place while the flue gas was
being sampled.
b. The O
2
sensor is faulty, is not connected correctly or
is not connected at all. Check the above points, also
referring to sections 5.3, 5.4, 6.6.
c. The sensor was not allowed the necessary
adjustment time or the instrument was left with a low
battery for too long.
A pressure sensor error is shown in the pressure/draft
screen.
There is a calibration problem. Send the instrument to
a service center.
The analysis screen gives a flue gas temperature (Tf)
error.
a. The thermocouple is not connected; connect the
thermocouple to the analyzer.
b. The sensor has been exposed to temperatures
greater or lower than its operating temperature range.
c. The thermocouple is faulty. Send the complete
probe to a service center.
The following symbol "----" appears on the analysis
screen.
The instrument is not able to calculate a numerical
value based on the flue gas analysis conducted. The "-
---" are replaced by numbers when the analyzer
detects valid combustion data.
"Max. Lim." or "Min. Lim" appears on the analysis
screen.
The relative sensor is detecting a value that is beyond
the analyzer measuring range. "Max. Lim" or "Min.
Lim." are replaced by numbers when the instrument
reveals values that are within the measuring range.
The sample pump sounds as though it is running
slowly, tends to stop or does not even start.
a. Sample flow is obstructed. Check that the water filter
is clean and that it is not completely soaked. Also
check that the hose connected to the probe is not
crushed.
b. Sample intake flow is obstructed. Check that the
particulate filter is clean.
c. The pump is not connected as it should be. Remove
the rear flap and check that the pump’s electrical
connector is connected to the printed circuit board.
d. Pump is faulty. Replace the pump unit.
e. Pump is disabled. The key combination
has been pressed. To re-enable the pump, switch off
the instrument and then switch it on again.
