<p>AUTOMATIC MILK BULK TANK LOCKOUT SYSTEM AND METHOD OF USING SAME An automatic milk bulk tank lockout system for use with a milk agitator in a stationary bulk tank and a pump in a milk tank truck for pumping milk out of the bulk tank includes an electrical receptacle adapted to supply power to the pump. A second timer switch driven by a timing motor is adapted to activate an agitator relay to direct electrical current to the milk agitator for a selected period of time. A third timer switch also driven by the timing motor selectively activates the receptacle in automatic coordination with the operation of the milk agitator. The receptacle is deactivated throughout the agitating period. Thereafter it is activated, whereby the pump is not powered and milk cannot be pumped out of the bulk tank before expiration of the selected agitating period. Preferably, the third timer switch controls a receptacle relay through which electrical current is directed to the receptacle activating it.</p> |
