Configuring the SeaHawk LD5100 as an Analog Input:
The FMS averages/filters the analog inputs. Therefore, the alarm delay for RLE’s SeaHawk LD5100 input
must be set to a value equal to or greater than the averaging time set in the FMS. The LD5100 will output
4mA when there is no leak. The LD5100 will output a value between 4mA and 20mA when there is a water
leak. The low range (4mA) will always correspond to zero feet. The high range (20mA) will always
correspond to the LD5100’s set 4-20mA Max Range (1000, 2500, or 5000 feet).
