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.
