16 TROUBLESHOOTING
16.1 Troubleshooting guide
PROBLEM PROBABLE CAUSES AND POSSIBLE SOLUTIONS
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 a 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 cells.
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/ draught
screen.
There is a calibration problem. Send the instrument to a service centre.
The analysis screen gives a flue gas temperature (Tf) error.
a.
The thermocouple is not connected; connect the thermocouple to
the analyser.
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
centre.
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 analyser 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 analyser’s
measuring range. "Max. Lim" or "Min. Lim." are replaced by numbers
when the instrument reveals values that are within the measuring
range.
The suction pump makes a slow sound, tends to stop or
does not work at all. a. The suction flow is hindered. Check that the filter unit is clean and
there is no condensation. Also check that the hose connected to the
probe is not crushed.
b. The suction flow is hindered. Check that the particulate filter is
clean.
c.
The electrical connection to the pump is not correct. Remove the rear
cover and check that the electrical connector of the pump is connected
to the electrical circuit.
d. Faulty pump. Replace the group pump.
e. The pump was disabled by simultaneously pressing the keys
To reactivate it, the instrument must be switched off and then on
again.
