Abstract
A fluid status detection system includes a plurality of probes connected to a controller. The controller includes a number of relays that may be programmed to latch either open or closed upon receipt of any one of several different alarms from the probes. The system includes a function that if a relay is latched and a second alarm occurs, then the relay releases for a second, then relatches. The system permits an operator to select the release and relatch latch function individually for each of the relays and to store the selection in a digital memory.
