LED STATUS
The LED on the connector panel provides valuable
troubleshooting information on the status of your
weather system.
The LED blinks green while the system is operating
normally. If the unit detects a problem, the LED blinks
amber to indicate a warning or red to indicate an error.
The pattern ot the LED blink is a code representing the
nature of the problem. For multiple warnings/errors
the codes are given in sequence with a 1.5 second pause
between the indications.
It is normal during the fi rst minute of initial power that
the SR100 status LED shows no activity and remains
off. During the second minute the status LED will start
to fl ash the amber or red fault strings. Typically, during
normal operation, a fl ashing green LED will occur within
90 seconds of initial power. If there is no LED indicaiton
of any sort displayed after 90 seconds you should check
the circuit breaker.
A blinking red LED indicates an internal fault condition and
a marine electronics technician should be contacted.
