Purpose Control Lines for Atlas Electronic Series
4 – Control Lines for Atlas Electronic Series
Purpose
This section is provided to familiarize the installer with control inputs and outputs that are
available for the Atlas electronic series dispensing unit. It is recommended that installers read
these descriptions to obtain a better working knowledge of the unit to guide them in planning
the site wiring. For specific wiring diagrams and installation notes, refer to
“Installation”

on page 6-1 .
Atlas electronic series units may be provided for use with 230 VAC power for international
applications. The operating voltage for control lines to these units is shown in parentheses as
(230 VAC International).
If you are connecting the Atlas electronic series unit to a Gasboy Fuel Management System
(FMS), refer to the following documents:
Grounding
To ensure proper operation of the equipment and required safety factors, a good ground line
must be provided. A ground wire (preferably green) must be connected between the ground
wire of the system and the main electrical service panel. One earth ground connection is
required per unit. The ground rod must be a solid, corrosion-resistant conductor and must be
installed at the main electrical panel as per the National Electrical Code (NEC). It must be
properly tied into the ground bus strip of the panel. It is recommended that neutral and ground
bus strips be bonded together (unless prohibited by local codes).
Ground Fault Interrupter (GFI) breakers are required for DEF only units installed on and with
a skid tank platform because of no underground piping, AC power in potentially wet area, and
a potential for earth ground to become broken if skid tank moves.
A GFI works by having a sensor that detects changes in current to the load, by comparing the
current owing to and from the load. A drop off in the current equivalent to about 5 mA, turns
off all power by tripping a relay within the GFI within a few hundredths of a second.
When powering a dispenser with a GFI, any device that the dispenser supplies power must
have its return to the same neutral as the dispenser. For example, the STP control relay.
