Electro-mechanical Registers and Totalizers
About Displays
Depending on the configuration, Atlas units may have electronic or mechanical registers or
totalizers. Totalizers provide a cumulative total similar to the odometer reading on a vehicle.
The display provides the customer with information about the total cost and total volume of
the fuel dispensed. PPU displays the PPU information to the customer.
Electro-mechanical Totalizer
An electro-mechanical totalizer is used for Electronic units. This replaces the cable-driven
accumulative totalizer for Electronic units. This totalizer is driven off the RS-485 and Pulse
Output Boards on the 9800 series and Hydraulic Interface Board on the 8800 series.
Figure 5-44 on page 5-51 shows details of the Electro-mechanical Totalizer [M00455A003
(Retail units)]. In the electronic layout of Atlas pumps, there are two electronic totalizers, one
each on Side A and Side B. The sides are connected by the M04889A001 Cable through 4-pin
connectors J922A and J922B. The Electro-mechanical Totalizer for 9800 series is
M00455A002.
