Axetris AG LGD F200P2 Operating Instructions - Rev D 19.09.2018 46/60
4.2 Troubleshooting
If you have problems while using the measurement software, please check if

LabVIEW RTE is successfully installed

The sensors’ power supply is plugged-in and properly working

The serial connection is set and data transmission is working

The correct serial port is set on startup
If a software problem occurs, it is important to send to Axetris the stored data (*.TXT and *.LGD files). This
allows Axetris to analyze the system monitoring data and helps to identify the reason for the problem.

If the LGD F200P2 measurements do not correspond to the expected values, please check
that the sensor is used within the specified operation and calibration range.
After verifying the factors above, follow the troubleshooting procedures outlined here below:
Problem Possible cause Solution
No signal / No value output No power supply or wrong polarity Check wiring
Measurement cell temperature
does not stabilize at desired
temperature Wrong polarity on heater power
supply Check wiring
The heating time is > 30 min
(when started at 25°C / 77°F,
ambient temperature) The power supply used for the heater
is not able to supply up to 8 A Check max current of used power
supply or change power supply
No reaction when target gas is
flowed in Condensation in system Flow with dry and dust-free air in the
Gas inlet and in the Purge inlet for at
least 15 min
Every 10 or 11 acquisition points
the time between points is
longer When the target gas concentration is
below a certain limit, the sensor has
an internal check which lasts longer
(around 2s) Flow with higher amount of target gas
The T90 is longer than expected The flow is lower as 3 l/min Increase the flow rate
