8100/8200 Monitor Instruction Manual
6 Maintenance
To maximise the operational life of the monitor and sensor, regular inspection is recommended. The frequency of this
is dependent on the specific operation of each site, however an initial weekly inspection to observe the characteristics
of the application is recommended, long term operational practice can be decided from these inspections.
The manual clean system requires the physical removal of the sensor from the application for the cleaning of the
lenses to be carried out.
It is advisable that at regular intervals the sensor is removed from the application and both the lenses and the sensor
body are cleaned along with the mounting brackets.
6.1 Inspection
It is envisaged that an inspection of the monitor and sensor will include the following:
• Check security of brackets
• Removal of the sensor from the application.
• Checking for damage to cables.
• Cleaning of the sensor using a suitable detergent and removal of all ragging.
• Inspection of the glass lenses for staining, scouring, cracks or chips.
• Checking for moisture/signs of leakage inside the sensor and monitor.
6.2 Fault Finding
The following can cause a false alarm or fault signal:
• Material (rag, weed, etc) caught on the sensor and affecting the measuring system - remove sensor, manually
clean and re-install.
• Turbulence (caused by high flow, aeration etc) in the solution being measured – position the sensor so
turbulence has as minimal effect as possible on the sensor.
• Bad connection of the sensor cable - check all connections are securely fastened
