B.1. Configuring the SeaHawk LD5100 as an Analog
Input
The F3400/F1000 averages/filters the analog inputs. The LD5100 will output approx. 3.95mA
when there is no leak. The LD5000 will output a value between 4mA and 20mA when there is a
water leak. The low limit 1 and low limit 2 set points should be set to a 0 value. High limit 1
should be set to a value, in feet, that represents 4.0mA (1 foot). This allows the F3400/F1000 to
alarm whenever there is a leak. The high limit 2 should be set to a value, in feet, that will control
the internal relay, if needed for the application. The Cable Fault relay, from the LD5100 should
be tied back into the F3400/F1000 to detect a fault with the 5100 controller/cable. The analog
output is only used for a Leak alarm distance.
