1. A method of detecting a pressure sensor failure in a water distribution system, the water distribution system connected to a pump with a motor, the method comprising:
- detecting a first pressure sensor signal;
shutting down a drive to the motor if the pressure sensor signal is outside of a sense range;
attempting to detect a second pressure sensor signal after power has be reapplied to the drive; and
allowing the drive to remain shut down until a second pressure signal is detected.

Abstract
A method and apparatus for a pump control system. One or more embodiments of the invention include a pump controller that can perform a self-calibrating procedure, can provide precise motor speed control, can provide a limp mode before shutting down the motor when system parameters are exceeded and/or fault conditions occur, can detect fault conditions, and can store fault conditions for later retrieval.

6. A method of operating a pressure sensor in a water distribution system, the water distribution system connected to a pump with a motor, the method comprising:
- detecting a pressure sensor signal;
disabling a power supply connected to the pressure sensor if the pressure sensor signal indicates that the power supply is shorted; and
generating a fault condition code and shutting down a drive to the motor if the shorted power supply is a selected sensor input for the pressure sensor. - View Dependent Claims (7, 8)
