7.5 Diagnostic LED Indicators Within the Enclosure
Two green LEDs labelled "LASER ON" and "STATUS" are visible on the DSP
(see Fig 7.3). 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 duplicates the LED visible through the top window.
There is a red LED on the PSU. It will give 0.5 second flashes as follows:-
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.
