5.1 Examine and clean the sensor
Do not use force, abrasive materials, chemicals or high-pressure washers or hoses to clean the sensor as
damage to the measuring end of the sensor can occur.
At regular intervals and before calibration, make sure that the measuring end of the sensor is not
covered with unwanted material.
1. Remove the unwanted material that has collected on the sensor.
2. Gently wipe the measuring end of the sensor with a non-abrasive cloth or paper.
3. Use a wet cloth or paper to remove dried material from the sensor.
5.2 Replace the sensor cables
Replace the sensor cables if the sensor cables have damage or as necessary (e.g., to install longer
sensor cables).
When a cable guard is installed on the sensor, refer to the illustrated steps that follow to replace the
sensor cables.
Note: When two sensor cables are used, the sensor cables must be attached to each other with zip ties to keep the
EMC compliance rating, unless the sensor cables are installed in conduit.
