R NOTE : You can get more data from the Aircraft Schematic Manual (ASM)
____ R (Ref. ASM 28-26/01) (Ref. ASM 28-46/03) and (Ref. ASM 28-46/04).
R (1) If the FAULT legend of the P/BSW-5QL comes on, set the P/BSW to OFF R (released out) to prevent a possible fuel spill.
R (2) Make sure that the C/Bs 1QL and 2QL are closed.
R NOTE : The 28VDC supplies related to this procedure are as follows:
____ R - C/B-1QL supplies the level sensor 28QJ1 channel in the R FLSCU-1 (7QJ) and the actuator control valve of jet pump 1 R (center-tank, left-side transfer) R - C/B-2QL supplies the FAULT indication circuit in the R P/BSW-FUEL/CTR TK/L XFR (5QL).
R (3) Do the Functional (BITE) Test of the FLSS (Ref. AMM TASK 28-46-00-740-001).

R

R (a) If the message:
R
R - is shown, do step (5) and then step (6)
R
R - is not shown, do step (6).
R

R (5) Do the TSM procedure (Ref. TASK 28-46-00-810-812).
R

R (6) Do the Operational Test of the Main Transfer Control System (Ref. AMM

 TASK 28-26-00-710-001). R R - if a new fault occurs (or shows during the Operational Test) refer R to Troubleshooting, Fault Symptoms with the new related fault R symptom(s) to find the applicable TSM procedure number(s) R R - if the test operates as specfied, do the steps given in Para. 4.A.
 4. Fault Isolation
_______________
R A. Procedure

R (1) Get access to the left wing fuel-tank inboard side of Rib 22 (Ref.
R AMM TASK 28-12-00-200-001).

R (2) Do a check of (Ref. AMM TASK 28-12-00-200-001) and replace, if
R necessary, the items that follow (Ref. AMM TASK 28-11-42-000-002) and
R (Ref. AMM TASK 28-11-42-400-002):
R - the forward CLACK VALVE (214QM)
R - the rear CLACK VALVE (216QM).

R (3) Do the TSM procedure Unwanted (Spurious) Warnings/Indications
R involving the SDAC-1 (1WV1) (SDAC-2 (1WV2)) (Ref. TASK 31-55-00-810-R 801).

R (4) If the fault continues, do the Fault Isolation Procedures (in Para.
R 4.A.) of the TSM Tasks that follow:
R

R (a) Transfer Control Valve 1 (Left) does not close - (Ref. TASK 28-26-00-810-804). R
R (b) Main Transfer System Auto Control Failure - (Ref. TASK 28-26-00-810-801).
