Abstract:
A fuel dispensing facility, comprising:(a) a plurality of multiproduct dispensers (""MPD's"") connected to a common fueling source;(b) a power circuit array including an individual power circuit for each MPD;(c) MPD switching means interconnecting said power circuit to a fueling control circuit for controlling operation of the fueling source;(d) a control input source solely and directly derived from the power circuit array for controlling operation of each of the MPD's, said control input source including means for receiving both an automatic and manual input signal indicating that a single MPD should be isolated from the power circuit array and an input signal indicating that all MPD's should be isolated from the power circuit array and a manual input signal indicating that all MPD's should be isolated from the power circuit array; and(e) modular control circuit means connected in series to each of said power circuit array, said modular control circuit means including MPD power circuit isolation means for isolating each individual MPD power circuit from each of the other MPD individual power circuits in the power circuit array.
