Abstract:
1. A method of assuring drop out of a valve assembly, the method comprising the steps of: receiving, at the valve assembly, a signal from a controller; detecting a level of the signal from the controller; diverting, in response to the level of the signal from the controller being above a predetermined value, at least a portion of the signal from the controller to a solenoid coil of the valve assembly, the level of the signal diverted to the solenoid coil being above the predetermined value; and diverting, in response to the level of the signal from the controller being below the predetermined value, at least a portion of the signal from the controller to a load, the level of the signal diverted to the load being below the predetermined value, wherein a level detector determines whether the signal from the controller is above the predetermined value before the signal is received by the solenoid coil or the load.
