IL55 and IL55BV2 Sensor Instruction Manual

7  Maintenance

7.1  Sensor Cleaning

The frequency of cleaning and servicing of the sensor is dependant upon the application in which it is being used, and 
the conditions present on site. It is advisable that, if possible, the sensor is regularly observed in the period after 
installation. It is from these observations that the cleaning intervals should be determined to suit the level of fouling 
experienced in the particular installation.

The sensor is not self-cleaning and the optical surfaces of the sensor will be subject to fouling. It is advisable that this 
fouling is not allowed to build up to such an extent that it affects the sensors ability to make the required measurement.

Cleaning should be carried out with a soft non-abrasive cloth. Where fouling is particularly bad or where the fouling 
has dried onto the optical surface a detergent or weak acid solution can be used. Care must be taken not to damage 
the optical surface.

7.2  Inspection

It is envisaged that an inspection of the sensor will include the following:

Check security of mountings.

Check for damage to cable.

Removal of the sensor from the pipe.

Cleaning the sensor using a suitable detergent and removal of debris.

Inspection of the glass lens for staining, scouring, cracks or chips.

Check for moisture/signs of leakage inside the glass lens.

7.3  Fault Finding

Any faults that occur which are not a result of incorrect system configuration can be due to the following:

Excessive fouling of the sensor lens - remove sensor, manually clean and re-install.

Check the lens assembly is not damaged.

There is a poor connection in the sensor cable - check all connections between sensor and controller.

A fault has occurred with the measurement system in the sensor.

Further fault finding information is contained in the monitor instruction manual.
