12 Diagnostics and troubleshooting
12.1 General troubleshooting
12.1.1 For the local display: Transmitter with touch screen
Problem Possible causes Remedial action
Local display dark and no output signals. The supply voltage does not match the
specifications on the nameplate. Apply the correct supply voltage.
Local display is dark, but signal output is within
the valid range. Display is set too bright or too dark. Set the display brighter or darker using the
"Brightness" function via the "Teqwave Viewer"
operating tool.
Display module is defective. Contact Hauser Service.
12.1.2 For the local display: Transmitter with LEDs
Problem Possible causes Remedial action
LEDs on the measuring device are not lit and no
output signals. The supply voltage does not match the
specifications on the nameplate. Apply the correct supply voltage.
LEDs on the measuring device are not lit, but
signal output is within valid range. Display module is defective. Contact Hauser Service.
12.1.3 For output signals
Problem Possible causes Remedial action
Signal output outside the valid range. Incorrect configuration. 1. Check the configuration and correct if
necessary.
2. Stay within the specifications for the
outputs indicated in the "Technical data".
3. Pay attention to the failsafe mode of the
outputs indicated under "Signal on alarm"
in the "Technical data".
Device shows correct value on the local display
but the signal output is incorrect, though in the
valid range. Configuration error. Check the configuration and correct if necessary.
Measured value is not stable. Operation outside the range of application. 1. Ensure the homogeneous mixing of the
liquid and continuous flow of liquid to the
sensor.
2. Remove air bubbles and/or particles.
3. Ensure the temperature value is stable.
Unfavorable configuration. Check the configuration of the "Averaging"
parameter. The following values are
recommended:
• Temperature: 10
• Speed of sound: 5
• Concentration: 5
Measuring device measures incorrectly or
concentration value is zero Concentration app not used correctly. Check the concentration app selected and
change the app if necessary.
Communication error Restart the transmitter. In doing so, disconnect
it from the supply voltage for at least 30 s.
