__________________

 A. Job Set-Up
 (1) Aircraft Maintenance Configuration
 (a)
 Energize the aircraft electrical circuits (Ref. AMM TASK 24-41-00-861-002).

 (b)
 Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only) (Ref. AMM TASK 31-60-00-860-001) - on the ECAM control panel, push the BLEED key (on the lower

 ECAM display unit, the BLEED page comes into view).
 B. Test
 (1) Do the operational test of the BMC1 (with the CFDS) (Ref. AMM TASK 36-11-00-740-001).
 4. Fault Isolation
_______________
 A. If the test gives a maintenance message, you can find the related trouble shooting procedure in the applicable Page Block 101.
 (1) If there is no message:
 -do a check of the sense line unions upstream of the bleed transferred pressure transducer (7HA1).
 (a)
 If the unions are loose, tighten these unions again (specified torque value is 1.6 m.daN) and stop trouble shooting.

 (b)
 If the unions are correctly tightened and if the fault continues:

 1_ Disconnect the electrical connectors from the bleed
 transferred pressure transducer (7HA1) and from the bleed
 regulated pressure transducer (8HA1).
 2_ Install the TEST SET - ENGINE BLEED SYSTEM (98D36003000000) or
 TEST SET - ENGINE BLEED SYSTEM (98F36003002000).
 3_ Connect the cable from the test set between the bleed
 transferred pressure transducer (7HA1) and the bleed regulated
 pressure transducer (8HA1).
 4_ Disconnect the sense line from the bleed pressure regulator
 valve control solenoid (10HA1) and blank the sense line union.
 5_ Disconnect the sense line from the bleed pressure regulator
 valve (4001HA) and connect to the test set.
 6_ Do this check:
 (Ref. Fig. 201/TASK 36-11-00-991-002)

ACTION RESULT -------------------------------------------------------------------------------
1.
 On the test set:  The pressure gage of the air cylinder Open the shutoff valve of the air shows the pressure. cylinder.

 2.
 On the test set:  The primary gage shows 35 psig. Use the primary regulator to pressurize the pressure source to 35 psig.

 3.
 On the test set:  Make sure that the same indication is Slowly pressurize the system up shown on the lower ECAM display unit. to 30 psig.
