Abstract
A liquid level sensing module for sensing a high liquid level in a sump container rising comprises a first liquid-actuated switch which provides a first output signal upon the liquid level reaching a first level, and a second liquid-actuated switch which provides a second output signal upon the liquid level reaching a second level above the first. A delay circuit delays the first output signal by a period if time sufficient for the liquid to rise from the first switch level to the second switch level to produce a delayed output signal. An alarm circuit produces a fault signal indicating a switch module fault upon the occurrence of the second output signal. An alarm circuit produces a fault signal upon the occurrence of the second output signal in the absence of the first output signal, or upon the occurrence of the delayed output signal in the absence of the second output signal, and the occurrence of either the delayed output signal or the second output signal, producing an alarm signal indicative of the pump failing to function.
