FACTORY SETTING )
The blinking Caution LED is controlled by a timer that is re-triggered, i.e., extended in
time, by the detection of any lightning within range of the Sensor. The nominal minimum
Caution Time Interval is approximately 35 minutes. For example, if only one lightning
message of the CAUTION category is received, then the front panel Caution LED will
flash for approximately 35 minutes. The Caution Time Interval is fixed and is set to
always be longer than the longest Alarm Time Interval setting of 30 minutes.
Lightning flashes in the Alarm category are most likely to have occurred within 5 miles of
the Sensor. Lightning flashes in the Warning category are most likely to have occurred
within 10 miles of the Sensor. Lightning flashes in the Caution category are most likely
to have occurred within 20 miles of the Sensor.
Setting the Alarm Category Threshold to Caution ensures the greatest number of
lightning alarms, maximum downtime and the greatest margin of safety. Setting this
option to Warning typically gives a medium level of downtime and moderate level of
safety. Setting this option to Alarm, typically gives the least number of lightning alarms,
minimal downtime and the lowest level of lightning safety.
