Green LED
The green LED indicates what the application in the Argon is doing, and any faults that it encounters. In normal operation,
the green LED will blink between 1 and 5 times, within 20 seconds or so of the last activity. The normal operation
indications are:
Number of Flashes
Description of action
1
Main loop processed
2
Read temperature
3
Alert triggered
4
Log triggered
5
Notify successful
Normally there will be a single flash to indicate the start of the loop followed soon after by 2 flashes to indicate a
temperature read. What happens after that will depend on the alarm and log settings set up when the unit was configured.
If no further action is required by the application after a temperature read, the main loop should commence again after
about 20 further seconds.
Error messages described by the Green LED are:
