SYSTEM LAYOUT
PURPOSE
Use this section for detailed planning of the installation of your system. This section covers a
basic description, location requirements, and the environmental requirements of the CFN
components. A dimensional drawing is included for components manufactured by GASBOY. This
section also covers conduit requirements and gives conduit layout examples for three basic
system configurations. Careful planning for the layout of the site will help eliminate possible
problems with the start-up of your system and will help ensure continued, reliable system
operation.
CFN ISLANDER
Description
The CFN Islander II is the heart of the CFN System at the fueling site. The Islander consists of a
Site Controller II, which controls and allows interaction between all your automated fueling
equipment including pump control devices and satellite Islander readers. In the Islander, the Site
Controller II comes standard with two PCMCIA card slots and two PCMCIA SRAM cards for mass
storage of data and loading in of operating system programs. The Islander II can be ordered to
provide magnetic or optical card or cardless operation. A built-in keyswitch can be used to limit
access to specified commands. The Islander can control up to 32 hoses and up to 7 satellite
readers (Islander readers).
The Islander comes in two post configurations, a standard post and a receipt printer post.
If pump control units are required, the standard pedestal can accommodate two pump control
units controlling up to eight hoses. The receipt printer pedestal can accommodate one pump
control unit controlling up to four hoses. Remote wall-mount pump control unit(s) can also be
used.
The Islander contains four asynchronous ports for terminals, modems and/or computer
communications. The ports can be set for either RS-232 or RS-422 communications to meet
individual requirements. Port 0 is used for communications to a data terminal (logger). Port 2 is
used for communication through a modem or to a computer. Ports 1 and 3 are additional ports
which can be programmed according to the application.
Two RS-485 ports are provided for communications with other CFN devices at the fueling site.
Location
The Islander should be located on the fuel island. The unit has been designed for an operating
temperature range of -40
o F to 104 o F with a relative humidity of 2% to 99% non-condensing.
Adequate clearance must be provided to allow easy access to the post’s access covers.
The Islander requires a minimum of 18 inches clearance between the post and any of the
pumps/remote dispensers on the island.
