SYSTEM AND PUMP/DISPENSER WIRING

System/Peripheral Equipment: AC Power for the system

components must come from a separate, dedicated circuit
breaker. No other equipment, including the system's pumps or
dispensers, may be powered from this breaker. Whenever
possible, one breaker should be used to supply the CFN system
components, terminal, and modem. However, it is accept able to
supply the power to different CFN system components and
accessor ies from multiple br eakers within the same panel and
the sa me phase of pow er. If necess ar y, the term inal or modem
may be on a di ffer ent separ ate, dedi cated breaker .

Power: 120 VAC + 10% 47-63 HZ.
Power conditioner: Optional.
Grounding: All system grounds must return to the same breaker

panel to ensure a common gr ound and protect the RS-485 data
loop circuitry.

Pulsers: Reed (contact closure) type pulsers require two wires
per pulser. Electronic pulsers require three wires per pulser.
See Pulser Wiring later in this documen t.

SUCTION PUMPS

The CFN pump control unit is capable of directly driving pump
motors up to 3/4 HP at 120/240 VAC or 1-1/2 HP at 240 VAC.
A start er rel ay must be used wit h pum p motor s exceed in g these
limitations. A separate circuit breaker should be supplied for
each pump to meet the current requirements and to allow for
isolated control with the circuit breaker panel in case of
problems.

DISPENSERS

9800A ELECTRONIC PUMPS

Series 9800A electronic pumps do not use the CFN pump
control unit; they are wired as independent units. See the 9800A
Installation Manual, 035296 for details.

Page 8

The CFN pump control unit can directly drive submersible
pumps up to 3/4 HP at 120/240 VAC or 1-1/2 HP at 240 VAC.
A submersible starter relay must be used with pump motors
exceeding these limitations. A separate circuit breaker is
required for each dispenser directly driving a submersible pump.
Dispensers may be grouped together on a single breaker when
the subm ersible p ump has its own br eaker. No mor e than two
dispensers should be powered from one breaker to allow
isolated control with the circuit breaker panel in case of
problems.

WIRE SIZE

Wire Si ze

This table shows the required AC wire size for suction and
submersible pumps based on the HP rating of the pump motor
and th e distan ce from the cir cuit br eaker to th e pump/di spenser
for both 120 and 240 volt units. Use this table as a guide for
selecting the proper size wire according to the specific
inst allation requirement s for motor wi ring. All wi re should be
strand ed.

COMMUNICATION WIRING

Requirements

The CFN system utilizes RS-485, RS-422 and RS-232 modes
for communications to other CFN system components and
peripheral equipment. The Islander has four ports: two RS-485,
which are dedicated to communicating with other CFN
components; the other two are configurable for either RS-232 or
RS-422, for use with a terminal, modem, or PC. Phone line
(modem) communication may also be used when remote
commun ication to the site is desi red. In cases wh ere an I slander
internal modem is used, the remote port is not available for
external comm unication wir ing.

RS-485 Data Loop

RS-485 is used for communications between the Islander and its
peripherals. Communication takes place over RS-485 modular
cables provided with the system components and the RS-485
data loop field wiring.

Twisted pair shielded cable is highly recommended for RS-485
wiring. Although it is recommended that wires be run in a
conduit separate from AC wires, they can be combined in the
same conduit with AC wires providing UL-Listed cable with the
following specifications is used:

Conductor: 18 AWG stranded wire. 2 twisted-pairs.
Shield: Foil-wrapped 100% coverage and/or tinned copper braid
90% coverage
Drain Wire: Stranded, tinned copper, 20 AWG or larger/or
braided shield

UL-Listed, 4-conductor cable that meets the requirements listed
above. NOTE: Belden 1063A is UL-Listed but not CSA listed.

When using the above recommended cable or its equivalent,
RS-485 wires can be run with AC wires in metal conduit. The
shield drain wire must be connected to the system AC ground.
Only AC wi r es for th e syst em an d pum ps can be in st all ed in th e
AC conduit.

If using cable other than that recommended, the RS-485 field
wires must be installed in a metal conduit separate from any AC
wires.

Wiring over 100 feet must be C09655 or equivalent. Distance
from Islander to farthest CFN component is limited to 1000 feet.
Total length of all RS-485 wiring cannot exceed 1500 feet.

RS-485 modular cables required are supplied with the system.
These cables are not compatible with standard phone cables.
GASBOY su pp li ed ca bles a r e 8 feet l on g, howev er , if you n eed
to conn ect to a d evice with a modul ar conn ector, you m ust use
an RS-485 junction box to connect the device to the RS-485
wiring. The system components wiring diagrams on pages 6
and 7 sh ow proper conn ection of th e CFN components.

RS-232

RS-232 wiring is used for communication between the Islander
and EIA RS-232-compatible peripheral devices (terminal,
modem, printer, etc). Distance for RS-232 are as follows:

1-100 feet: RS-232 can be directly connected to a peripheral
device.
101-1500 feet: RS-422 and GASBOY Short Haul Modem
required.

RS-232 wiring exceeding 15 feet must be installed in metal
conduit separate from any AC wires.

OPTIONAL MODEM REQUIREMENTS

GASBOY RS-422 Short Ha ul Modems

A GASBOY Short Haul Modem (SHM) and the appropriate
interconnect cable must be used when the RS-422
communication mode is being used to communicate to the local
or remote ports of the Islander. The SHM should be used for
distances between 100 and 1500 feet. One SHM is required at
the remote end of the communication wiring. SHM's must be
connected with private lines and will not work if connected into
a telephone network.

AC power should come from the same breaker that supplies the
peripheral devi ce or the system .

Twisted pair shielded cable is highly recommended for RS-422
wiring. Although it is recommended that wires be run in a
conduit separate from AC wires, they can be combined in the
same conduit with AC wires providing UL-Listed cable with the
following specifications is used:

Conductor: 18 AWG stranded wire. 2 twisted-pairs.
Shield: Foil-wrapped 100% coverage and/or tinned copper braid
90% coverage

Drain Wire: Stranded, tinned copper, 20 AWG or larger/or
braided shield
Voltage Rating: Maximum operating voltage of 600V
Environmental: Gas- and oil-resistant; suitable for wet or dry
locations.

GASBOY can supply Belden 1063A (P/N C09655) which is a
UL-Listed, 4-conductor cable that meets the requirements listed
above. NOTE: Belden 1063A is UL-Listed but not CSA listed.

When using the recommended C09655 or its equivalent, RS-422
wires ca n be run with AC wires in meta l conduit. The shi eld
drain wire must be con nected t o the system AC ground. Only
AC wires for th e system and pumps can be install ed in the AC
conduit.

If using cable other than that recommended, the RS-422 field
wires must be installed in a metal conduit separate from any AC
wires.

The cabl e can be r un in doors without usin g meta l condu it. The
shi eld drain wire m ust be connected to the system g round.

External Modems

The type of phone line required for communication via an
external modem is contingent upon the type of modem used and
the method of communication desired. Consult the manual that
comes with the modem for specific requirements.

Internal Modem

The Islander is available with an optional internal modem.
When this modem is installed, remote port communication is
routed through the modem in place of being wired at the
terminal block in the post. The phone line for the internal
modem must not be installed in the DC conduit. Check with
your local phone company for proper installation of the phone
line.

The 2400 baud modem is designed for 300, 1200, or 2400 baud,
full duplex, asynchronous communication. The 33600 baud
modem is designed for 1200, 2400, or 9600 baud, full duplex,

Page 11

asynchronous communications. The modem is mounted inside
the Islander at the factory. Power for the modem is supplied by
the Islander.

The mod em i s d esig n ed t o meet or exce ed t h e d ir ect con n ect i on
registration requirements of the FCC rules. This means the
modem will connect directly with a jack supplied by the phone
compan y. Th e cust omer is req uired t o ord er thi s jack and have
it in sta ll ed. To or der thi s equi pm ent from the ph on e com pan y,
specify:

1. Any one of the following jacks: RJ11C or RJ41S, OR
RJ45S.

2. The registration number of 6BHUSA-24793-DT-E.

3. The data transmission rate of 300 baud, 1200 baud, 2400
baud, or 9600 baud.

4. The Bell equivalent of 103J/212A.

OPTIONAL FUEL PO INT

The Islander II system can be purchased or retrofitted with a
Fuel Poin t option. With Fuel Point, each vehicle is equipped
with a T-ring (tank ring). Each hose used with Fuel Point is
equipped with an N-ring (nozzle ring). When fueling the
vehicle, the antennas on the T-ring and N-ring automatically
transmit vehicle information to the Fuel Point Reader (FPR),
which in turn, transmits this information to the GASBOY
Islan der II system which authoriz es fuelin g and record s vehicl e
and transaction information.

The h ard war e r equir ed for th e F uel Poi n t opti on can be fact or y­installed on a new system, or retrofitted to an existing system.
Refer to the following Fuel Point manuals for information on
system installation and ret ro fitting:

• Fuel Point Reader Installation, C35628

• Fuel Point Hose and Dispenser Retrofit Installation,

C35593

• Vehicle Module Installation, C35699

• Vehicle Module Programming Manual, C35629

• Fuel Point Parts, C35709

Ther e are two var iati ons on th e Fuel Poin t opti on: the s tandar d
Fuel Point option or the Fuel Point Gate option. The standard
option allows you to authorize up to 8 fueling positions. The
gate op tion allows y ou to designate a fueling position ( ho se) as a
gate controller. The gate option requires a special vehicle
module with gate antenna connectors on the vehicle and
installation of a special ground loop antenna buried in the
driveway.

GATE CONTROLLER WIRING USING GATE READER

The Islan der system ca n activa te a gate contr oller by usin g the
CFN Gate Island Reader or Gate Satellite Reader. Either of
these Gate Readers allows activation by card, Fuel Point, or
terminal command, but not via console or POS terminal.

• The CFN Gate ICR can directly switch power to a gate

controller. The maximum ratings of the switched power is
not to exceed 5A @ 30VDC or 1/8HP @ 120VAC. If the
gate controller switch control exceeds those ratings, an
auxiliary relay must be installed to handle the load. The
auxiliary relay coil is not to exceed the ratings mentioned
above.

• The Islander II system allows a loadable timeout value up

to two minutes during which time the relays are energized.
The selected time depends on the gate controller
manu facturer’s specification.

• Instead of a timed closure, the system also allows the

relays to stay energized indefinitely until a signal comes
back to turn them off. The signal is 120VAC only, and is
connected to the I/O Board’s Switch Detect connector.
