A control circuit array for controlling operation of a plurality of multi-product fuel dispensers ("MPDs") in response to control inputs from a control input source. The control circuit array includes an electric power source, switches for fuel grade selection and MPD lighting and outputs to submersible turbine fuel pumps for supplying fuel to the MPDs. The improvement comprises a modular circuit board for being connected in series to form the control circuit array, wherein each circuit board includes emergency shutoff means for responding to a single em...
[ I claim:] [1.] 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 autom...
