HEAD ASSEMBLY
DESCRIPTION
The head portion of the Series 1000 is the heart of the system. Its physical layout is basically the
same for all three system types with the following differences: the card-activated system contains
a magnetic stripe insertion reader or an optical card reader; the cardless system contains no
reader; the FleetKey system has one or two key receptacles.
The head also contains the power supply, the pump control unit (PCU) PCB, the microprocessor
unit (MPU) PCB, and the auxiliary communication port PCB.
The drawings on the next three pages show the head as viewed from each angle:
● power supply side, page 2-2
● MPU PCB side, page 2-3
● top view, page 2-4
The three pages after that show the chassis wiring for each head type:
● mag card or cardless, page 2-5
● optical card, page 2-6
● FleetKey, page 2-7
