CAUTION:
If the window requires cleaning, it is very important that only a proper lens cloth or lens tissue
is used. The use of inappropriate materials to clean the windows can permanently damage or
reduce their effectiveness leading to reduced performance.
When the top cover is removed, avoid spraying the fan assembly with liquids. Use damp lens
wipes or a clean soft cloth to clean the windows.
Use an air duster to blow any loose dust and dirt from the window as a first step. Use a lint free
lens cloth or lens tissue impregnated with a non-aggressive standard window cleaner. Clean the
surface by dragging the cloth across it being careful not to apply excessive pressure.
Excessive pressure may lead to some types of contaminants scratching the window surface. Over
time such scratches can lead to reduced sensitivity.
7.3 Diagnostic LED indicators within the
enclosure
The LASER ON and STATUS green LEDs are visible on the DSP (see FIGURE 7-1 (p. 92)). Their
function is as follows:
LASER ON LED:
Off = laser off
Flashing = laser fault
On = laser on
STATUS LED:
1 flash every 10 seconds = OK
2 flashes every 10 seconds = warning (possible degraded performance)
3 flashes every 10 seconds = alarm (measurements not possible)
The DSP STATUS LED provides the same function as the LED visible through the top window.
The red LED on the PSU flashes for 0.5 seconds:
Permanently on = PSU firmware fault
1 flash every 10 seconds = PSU OK
2 flashes every 10 seconds = running in battery mode
3 flashes every 10 seconds = no communications to the DSP. This takes 60 seconds to start after
a communications failure.
