8800 Series Retail Electronics
The Atlas 8800 Series Electronics Cabinet is discussed in this section. The electronic parts are
listed in the previous page. The electronics manages all the common functions for a low hose
compact dispenser, such as sales control, maintenance, preset Automatic Temperature
Controller (ATC) functions, electro-mechanical totalizers, and other options. External
communications utilize a proprietary two-wire communication system used by a number of
POS controller manufacturers. Interface devices for communications such as a Pump Access
Module (PAM) 1000 can be used to convert two-wire communications to a usable format for
other POS manufacturers who cannot connect directly to the two-wire system.
Note: To interface to the Gasboy CFN Site Controller Systems, a Current Loop (ISL2, SC2) or
PC Interface Package (SC3) is used in place of the PAM.
System and Component Overview
In this section, cautions and warnings for electronic components will be addressed. Extreme
care must be taken while using explosive vapors or liquids, which may be present around the
dispensing equipment. These vapors can be ignited by flames, electrical arcs, or static
electricity discharges. An electrical shock hazard exists when working with this equipment.
An electrical discharge can cause injury, ignite vapors, or damage sensitive electronic
components. All safety precautions and requirements must be strictly followed.
