ELECTRO-MECHANICAL TOTALIZERS
Note: Because of rounding methods used and the nature of electronic totals versus an analog device (e.g. electro-mechanical
totalizer). Electronic totals and electro-mechanical totals will rarely match exactly.
The dispenser is equipped with an electro-mechanical totalizer for each hose that records the volume dispensed for each sale. The
volume recorded is an accumulative total that cannot be reset. The electro-mechanical totalizers are located below the product select
buttons on each side of the dispenser. The total is cumulative and reads in whole unit in gallon or liter increments.
RETAIL & COMMERCIAL DISPLAY REED SWITCHES
The Retail Display uses reed switches to recall the last sale if there is a power outage and to recall the electronic totals. These switches
are normally opened. An access magnet can be held over the left or right side of the “TOTAL SALE” or “VOLUME ONLY” display for
approximately 2 seconds. The reed switch will close and the display will provide either the last sale (during power outages), electronic
totals, or audit trail information. Refer to the 719 Technical and Dispenser Programming Manual for additional information.
ELECTRONIC– OVERVIEW
The electronics used on the 3000 series dispenser are located in the upper cabinet and lower cabinet for hydraulic control. All units have
conformal-coated electronic boards to help protect them from moisture or foreign material damage. All major electronic board
assemblies are environmentally tested and temperature cycled. Refer to the sections below for board descriptions.
719 CPU BOARD
The 719 CPU Board is the heart of the system. It runs the software, has dispenser memory, communicates with Point of Sale via
personality modules, and sends display signals to the display boards. It also stores historical data for sales and diagnostics. Refer to the
719 Technical & Dispenser Programming Manual for more information.
