ABSTRACT:
An apparatus and method for monitoring and controlling a motor driven sump pump. The apparatus and method includes a power supply which powers the apparatus, a sensing portion which detects the level of the liquid within the sump, a control portion which turns the motor either off or on in response to the level of the liquid, and an alarm portion cooperating with the sensor which activates an alarm when a preselected level has been reached. The apparatus and method also includes power failure detection portion cooperating with the alarm portion which activates an alarm when a power failure occurs, a fault detection portion cooperating with the alarm portion which activates an alarm when the fault condition occurs, and a disabling portion which disables the pump when the fault detection portion detects a fault condition in the pump.
