4. Procedure
Subtask 36-11-15-720-055-A
A. Functional Test of the Bleed Transferred Pressure-Transducer
   (1) Close the shutoff valve, the purge valve and the pressure regulator valve on the 98D36109001000 TEST SET-EBAS,BLEED.
   (2) Connect an AIR SOURCE - REGULATED, FILTERED, DRY to the 98D36109001000 TEST SET-EBAS,BLEED.
   (3) Connection of the 98D36109001000 TEST SET-EBAS,BLEED:
     (a) Connect the 98D36109001000 TEST SET-EBAS,BLEED with the short hose to the adaptor assembly.
     (b) Connect the adaptor assembly to the test port of the bleed transferred pressure-transducer.
     (c) Tighten the adaptor assembly.
   (4) Do a reset of the digital pressure gage.
   (5) Make sure that the regulator valve of the 98D36109001000 TEST SET-EBAS,BLEED is closed before pressurize the system.
   (6) Do the test that follows:
ACTION
RESULT
1.On the MCDU control panel:
  • Push the SENSOR STATUS key.
On the MCDU:
  • The SENSOR STATUS page comes into view and shows the bleed pressure.
2.Pressurize the 98D36109001000 TEST SET-EBAS,BLEED:
  • If there is a manometer on the AIR SOURCE - REGULATED, FILTERED, DRY, installation of the primary regulator valve is not necessary. Use the AIR SOURCE - REGULATED, FILTERED, DRY shutoff valve and the manometer to slowly pressurize the 98D36109001000 TEST SET-EBAS,BLEED to 200 psi (13.7895 bar).
  • If there is no manometer in the AIR SOURCE - REGULATED, FILTERED, DRY, installation of primary regulator valve is mandatory. In this case the primary regulator valve will limit the pressure in the 98D36109001000 TEST SET-EBAS,BLEED to 217 psi (14.9616 bar).

3.On the 98D36109001000 TEST SET-EBAS,BLEED:
  • Open the shutoff valve.
  • Use the regulator valve on the 98D36109001000 TEST SET-EBAS,BLEED to slowly pressurize the system from 10 psi (0.6895 bar) to 170 psi (11.7211 bar)
On the 98D36109001000 TEST SET-EBAS,BLEED:
  • The digital pressure gage shows the pressure.
On the SD:
  • The status page shows the supplied pressure, which must agree with the value of the digital pressure gage plus or minus 2 psi (0.14 bar).
4.On the 98D36109001000 TEST SET-EBAS,BLEED:
  • Use the regulator valve on the 98D36109001000 TEST SET-EBAS,BLEED to depressurize the system.
On the 98D36109001000 TEST SET-EBAS,BLEED:
  • The digital pressure gage shows 0 psi (0.0000 bar).
   (7) Close the shutoff valve of the AIR SOURCE - REGULATED, FILTERED, DRY.
   (8) Slowly open the purge valve to depressurize the 98D36109001000 TEST SET-EBAS,BLEED to 0 psi (0.0000 bar).
   (9) Disconnection of the 98D36109001000 TEST SET-EBAS,BLEED:
WARNING: BEFORE YOU START TO REMOVE THE TOOLING, MAKE SURE THAT THERE IS NO PRESSURIZED GAS LEFT INSIDE THE DUCTS. IT CAN CAUSE AN INJURY TO PERSONNEL AND/OR DAMAGE TO EQUIPMENT.
     (a) Disconnect the 98D36109001000 TEST SET-EBAS,BLEED from the test port of the bleed transferred pressure-transducer.
     (b) Disconnect the short hose from the adaptor assembly.
     (c) Disconnect the short hose from the 98D36109001000 TEST SET-EBAS,BLEED.
