 Aug 01/04 CES 4. Fault Isolation

_______________

 A. If the test gives:
 - the message HYD G RSVR OVHT on the upper ECAM DU,

 - the PTU P/BSW FAULT light on panel 40VU,

 - the GREEN ENG 1 PUMP P/BSW FAULT light on panel 40VU,

 - the OVHT flag on the HYD page of the lower ECAM DU:

 - measure the temperature with a temperature sensor adjacent to the XMTR-TEMP, G RSVR (1381GR).

 (1) If the temperature is more than 95 +2.2 -2.2 deg.C (203.00 +3.96 -
3.96 deg.F): R - do a check of the internal leakage of the Green hydraulic system R (Ref. AMM TASK 29-00-00-280-001) and the PTU (Ref. AMM TASK 29-00-R 00-280-004).
 (a) If the internal leakage is more than permitted:

 - examine the system to find the defective component.

 - replace or repair the defective component.

 (b) If the internal leakage is not more than permitted:

 - do a check of the filter elements of the DRAIN-HYDRAULIC FILTER CASE ASSEMBLY (1084GM), FILTER-HP, G (1048GM) and FILTER-LP, G (1002GM)

 (c) If the filter elements are dirty:

 - replace the filter element (Ref. AMM TASK 29-11-43-610-040) or (Ref. AMM TASK 29-11-44-610-001) or (Ref. AMM TASK 29-11-45-610-001)
 (2) If the temperature is less than 95 +2.2 -2.2 deg.C (203.00 +3.96 -
3.96 deg.F):

 - do a check for continuity between: the XMTR-TEMP, G RSVR (1381GR) connector A/A and connector A/B (Ref. ASM 29-33/01).
 (a) If there is continuity:

 - replace the XMTR-TEMP, G RSVR (1381GR) (Ref. AMM TASK 29-33-11-000-001) (Ref. AMM TASK 29-33-11-400-001).

 (b) If there is no continuity:

 - make sure that the wiring is not connected to GND between: XMTR-TEMP, G RSVR (1381GR) connector A/B and DIODE (1158VD) connector 13 (Ref. ASM 29-33/01).
 1 If the wiring is connected to GND:
_ - repair the wiring as necessary.

 Aug 01/04 CES (c) If the fault continues:

 - do the operational test of the central warning system (Ref. AMM TASK 31-50-00-710-001).
 1_ If the test gives the maintenance message SDAC1 : G HYD TEMP
 XMTR 1381 GR:
 - replace the SDAC-1 (1WV1), (Ref. AMM TASK 31-55-34-000-001)
 and (Ref. AMM TASK 31-55-34-400-001).
 2_ If the test gives the maintenance message SDAC2 : G HYD TEMP
 XMTR 1381 GR:
 - replace the SDAC-2 (1WV2), (Ref. AMM TASK 31-55-34-000-001)
 and (Ref. AMM TASK 31-55-34-400-001).

 B. If the test gives:
 - No messages on the upper and lower ECAM DU,

 - No FAULT lights on the panel 40VU:

 (1) Do the operational test of the VALVE-G PUMP FIRE, ENG 1 (1046GK) (Ref. AMM TASK 29-10-00-710-001).
 NOTE : If the VALVE-G PUMP FIRE, ENG 1 (1046GK) is not in the fully
____ open position, this can be the cause of an overheat of the hydraulic system.
 (2) If the operational test gives an unsatisfactory operation of the VALVE-G PUMP FIRE, ENG 1 (1046GK), replace the VALVE-G PUMP FIRE, ENG 1 (1046GK):

 - (Ref. AMM TASK 29-11-52-000-001) and

 - (Ref. AMM TASK 29-11-52-400-001).

 (3) Do a check of the engine pump for a possible cavitation condition (Ref. AMM TASK 29-00-00-280-006).

 NOTE : A cavitation condition of the engine pump is possible when the
____ engine pump operates with the engine pump fire valve closed (if you set the ENG 1 (2) FIRE pushbutton on the Eng/APU fire panel), or with the reservoir below the low level (ECAM indication).
 C. When the VALVE-G PUMP FIRE, ENG 1 (1046GK) was not the cause of the malfunction:
 - Do the test as given in Para. 3. B. to make sure that operation is correct (no message shown).
