R (7) Do the pressure refuel with auto control.

R (8) If the fault continues:

R (a) Set the MCDU to INPUT PARAMETERS page 3, (the bit position -R state cross-reference).

R (b) Examine the bit positions in the Table 1 that follows:

R NOTE : Not all the refuel signals are monitored by the FQIC to be

____ R shown on the INPUT PARAMETERS page 3. R The signals that are not shown on the INPUT PARAMETERS are R identified in Table 2 with the Para number given for R direct entry into the Trouble-shooting task.

R (9) For the automatic refuel mode to be active check the conditions that R follow in conjunction with the Table 1 above or as directed:
R (a) The ground/flight discrete input is set to ground:
R 1_ Remove the FQIC (3QT) from its rack connector (Ref. AMM TASKR 28-42-34-000-001).
R 2_ With a multimeter check to see if the FQIC rack connect pinR B05F is at ground potential.

R 3_ If pin B05F is at ground potential reinstall the FQIC (Ref.
R AMM TASK 28-42-34-400-001).

R 4_ If the pin B05F is not at ground potential do a wiring check
R of the:
R - aircraft wiring between the FQIC (3QT) rack connector pin
R B05F and MSW-REFUEL.DEFUEL CTL DOOR POSITION (20QU), (Ref.
R ASM 28-42/03).
R - aircraft wiring between the FQIC (3QT) rack connector pin
R B05F and RELAY-L/G POSITION, SYS 1 (11GB), (Ref. ASM 28-R 42/03).

R 5_ Repair all wiring and connectors.

R 6_ Reinstall the FQIC (3QT) (Ref. AMM TASK 28-42-34-400-001).

R (b) The refuel selected discrete is active. The logic for this,
R incorporated in the aircraft wiring, is condition 1_ or 2_ below:

R 1_ Refuel panel door open and the MODE SELECT switch on the
R external refuel panel set to REFUEL.

R 2_ The cockpit refuel panel power switch set to on, and the
R cockpit refuel panel CTL (Control) switch set to on.

R (c) All the REFUEL VALVE switches are set to NORMAL.

R (10) For an automatic refuel to start make that the conditions are as
R follows:

R (a) Refuel bus power has been present for sufficient time to allow
R the high level sensors to settle in thier true states.
