4. Procedure
Subtask 36-11-16-720-054-A

A. Functional Test of the Bleed Regulated Pressure-Transducer 8HA1(8HA2)
(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 short hose to the adaptor assembly.
(b) Connect the adaptor assembly to the test port of the bleed regulated pressure-transducer.
(c) Tighten the 98D36109001000 TEST SET-EBAS,BLEED.
(4) Set the digital pressure gage back to zero.
(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 100 psi (6.8948 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 of the 98D36109001000 TEST SET-EBAS,BLEED to slowly pressurize the system from 10 psi (0.6895 bar) to 90 psi (6.2053 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 of 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 adaptor assembly from the test port of the bleed regulated pressure-transducer.
(b) Disconnect the short hose from the adaptor assembly.
(c) Disconnect the short hose from the 98D36109001000 TEST SET-EBAS,BLEED.
