8 Maintenance
The LSP
HD
Linescanning Thermometer is specifically designed to minimise the need for
regular maintenance.
The recommended maintenance routine involves periodic checks on unit services and
ensuring that the scanner viewing window is kept clean and free from contamination.
8.1 Air Purge Services
The air purge system reduces the amount of dust or dirt reaching the viewing window
of the scanner. The effectiveness of the purge is dependent upon the air flow rate and
the nature of any airborne dirt.
Check the cleanliness of the window on a regular basis as part of your local
maintenance schedule. If the contamination rate is too high, then it may be necessary
to increase the purge flow rate.
It is of the utmost importance that the air supply to the purge system is of high quality
and is supplied clean and dry, otherwise window contamination may result, and the
diffuser within the purge unit may become blocked.
If the viewing window becomes dirty, clean it with a soft clean cloth. If stubborn
deposits are found, moisten the cleaning cloth with a mild detergent.
If the scanner viewing window gets damaged, the unit must be returned to AMETEK
Land for a window replacement.
8.2 Water And Air Cooling Services
The main problems associated with the water and air cooling systems are inadvertent
supply shut-off and over-cooling. Check the flow rate on a regular basis as part of your
local maintenance schedule. Use a flow rate monitor and alarm system.
Over-cooling causes condensation to form on the unit. To prevent this happening,
make sure that the water or air supply temperature is above the local dew-point
temperature.
8.3 Plate Mounted Blower Unit
Refer to the Plate Mounted Blower Unit User Guide (198.252) for details of maintenance
