4. Fabricate a power connection to the upper cabinet. A power cable may be fabricated from
components available through Tyco Electronics, and an AC power cord with 18AWG conductors
and a male connector. Select an AC power cord with sufficient length to reach from a wall outlet
to the Programmer. Ensure one end of the power cable has exposed black, white, and green
wires.
a. Strip approximately ¼ inch of insulation from the exposed ends of the black, white, and
green wires.
b. Obtain one Tyco Electronics 1-480305-0 connector housing, and three Tyco Electronics
60618-4 contacts.
c. Crimp the three contacts onto the exposed ends of the black, white, and green wires.
d. The connector housing has pin receptacles numbered 1, 2, and 3. The contacts crimped
onto the ends of the black, white, and green wires have keepers that hold the pins in the
connector housing. Push the contact on the white wire into the receptacle numbered “1” until
it bottoms in the housing. The keeper should retain the pin in the housing. Repeat with the
contact on the green wire into the “2” receptacle, and the contact on the black wire into the
“3” receptacle. When finished you should have a power cable with a male plug at one end,
and the connector housing at the other end.
5. Position the Programmer out of the way but within line of sight of the vehicles being fitted with
AIM2™.
6. Plug the connector housing end of the power cable into the female power receptacle of the FMU
upper cabinet. The connectors should be keyed so they will only connect one way. After
connection, verify the wires at both sides of the connectors match white to white, green to green,
and black to black.
7. Plug the power cable into a 115 VAC power outlet. After a brief power-up delay and initialization,
the FMU Programmer should display:
**FuelMaster FUELS ACCOUNTING SYSTEM**
** INSERT KEY OR CARD TO BEGIN **
8. Recommend the circuit breaker for the FMU pedestal be turned off, and a lockout/tagout tag
installed to let people know it should not be turned on.
9. Cover the opening at the top of the FMU pedestal to prevent rain/snow/debris from entering the
exposed pedestal.
Develop an FMU-3500 Programmer from an FMU-3500 demonstration unit: an
FMU-3500 demonstration unit may have all the hardware components to meet the task, but it may
not have the correct site signature and system type, nor may it be set to be a Programmer.
1. Set the correct site signature, system type, and Programmer option:
a. Determine the site signature and system type necessary to change the demonstration unit.
b. Plug the demonstrator unit into a 115 VAC power outlet. After a brief power-up delay and
initialization, the unit should display:
**FuelMaster FUELS ACCOUNTING SYSTEM**
** INSERT KEY OR CARD TO BEGIN **
c. A laptop connection to the demonstrator unit will be necessary to change the site signature
and system type, as required. Make the laptop connection in accordance with Product
Bulletin 111.
d. Use command 38 to change the site signature:
1) When the 38 command is sent to the FMU, the following display appears:
Entering Configuration Mode!
CURRENT SIGNATURE = 1234
NEW SIGNATURE (XXXX hex –or- #99999 dec) = ___
2) 1234 is an example. Enter the new site signature at the flashing cursor:
