Abstract
A fluid status detection system includes a plurality of probes connected to a controller. The controller includes a microprocessor, a digital memory, relays, and progammed so that selected alarm and relay latching conditions may be stored, and alarms activated and relays latched according to the alarm and latching conditions. The microprocessor is programmed to provide an alarm acknowledgement signal upon the alarm being acknowledged. An operator may select one or more release conditions individually for each relay from a plurality of possible relay release conditions and store the conditions in the memory. The possible relay release conditions include: the condition that the probe signal indicates that the event that caused the alarm has cleared; the condition that the alarm acknowledgment signal has been provided; the condition that the probe signal indicates that the event that caused the alarm has cleared and the the alarm acknowledgment signal has been provided. Upon occurrence of the selected relay release conditions, the system automatically releases the relay.
