Diagnostics and troubleshooting

9.1  

General troubleshooting

When troubleshooting, the entire measuring point must be taken into account:

• Transmitter

• Electrical connections and cables

• Assembly

• Sensor
The possible causes of error in the following table relate primarily to the sensor.

Problem

Testing

Solution

No display, no sensor reaction

• Power supplied to transmitter?
• Sensor connected correctly?
• Buildup on optical windows?

• Connect mains voltage
• Connect sensor correctly
• Clean sensor

Display value too high or too low

• Buildup on optical windows?
• Sensor calibrated?

• Cleaning
• Calibration

Display value fluctuating greatly

Is the mounting location correct?

• Select a different mounting location
• Adjust the measured value filter

Pay attention to the troubleshooting information in the Operating Instructions for the

transmitter. Check the transmitter if necessary.
