Description
Operation
The ERL-10 receives data from the EFM-100 Electric Field Mill short-range sensor (<20 miles/32 km) and a LD-250 long range lightning detector. It constantly monitors for lightning and activates its timed relay outputs when lightning is detected. Up to three alerts can be configured, referred to as Red, Orange, and Yellow Alert levels. The green All Clear state is entered when no lightning has been detected within the configured time period.
When the ERL-10 is first turned on, it enters Survey Mode where it looks for lightning. After several minutes without lightning (configurable but typically 10-20 minutes) the system enters the All Clear state. The green All Clear light on the ERL-10 illuminates and the All Clear relay output activates.
Dual Sensor Coincidence Mode
With Coincidence Mode enabled, a lightning strike must be detected by both the EFM-100 and the LD-250 in order for an alert to activate. This virtually eliminates false alerts that could be caused by persons, animals, insects, etc. near the EFM-100 sensor. Coincidence Mode is only applicable within the range of the EFM-100 (0-20miles/0-32km).
Status Monitor
The ERL-10 Status Monitor software (included) allows the system status and countdown timers to be displayed. Countdown timers clearly indicate the number of minutes until All Clear. Alert activations are timestamped and logged to disk. Graphical log file viewing software is also included.
