Functional Test of the Bleed Monitoring Pressure Sensor (BMPS) with the Bleed Test Set P/N 98L36103002000 and the Adaptor Kit P/N 98D36109004000

WARNING: MAKE SURE THAT THE PNEUMATIC SYSTEM IS DEPRESSURIZED BEFORE YOU START WORK. PRESSURIZED AIR CAN CAUSE INJURY TO PERSONNEL.

WARNING: BE CAREFUL WHEN YOU DO WORK ON THE ENGINE PARTS AFTER THE ENGINE SHUTDOWN. USE APPLICABLE THERMAL GLOVES. THE ENGINE PARTS CAN STAY HOT FOR ONE HOUR AFTER SHUTDOWN AND CAN BURN YOU.

WARNING: YOU MUST NOT TOUCH HOT PARTS WITHOUT APPLICABLE GLOVES. HOT PARTS CAN CAUSE AN INJURY.

WARNING: MAKE SURE THAT THE SAFETY DEVICES AND THE WARNING NOTICES ARE IN POSITION BEFORE YOU START A TASK ON OR NEAR:

THE FLIGHT CONTROLS
THE FLIGHT CONTROL SURFACES
THE LANDING GEAR AND RELATED DOORS
COMPONENTS THAT MOVE.

MOVEMENT OF COMPONENTS CAN KILL OR CAUSE INJURY TO PERSONS AND/OR DAMAGE TO EQUIPMENT.

WARNING: BEFORE YOU INSTALL/REMOVE THE GSE TOOL, READ THE MANUFACTURER'S INSTRUCTIONS, AND, WHILE YOU OPERATE THIS TOOL, CAREFULLY OBEY THEM. IF YOU DO NOT DO THIS, INJURY TO PERSONS AND DAMAGE TO EQUIPMENT CAN OCCUR.

WARNING: BEFORE YOU START WORK, YOU MUST PUT ON A SAFETY HARNESS AND ATTACH IT TO THE ACCESS PLATFORM. WITHOUT A SAFETY HARNESS, YOU CAN FALL. THIS CAN KILL YOU OR CAUSE YOU INJURY.

CAUTION: BE CAREFUL WHEN YOU CONNECT/DISCONNECT THE TEST SET TO/FROM THE EQUIPMENT. THE PRESSURE REGULATING VALVE AND THE PRESSURE GAGE ASSEMBLY OF THE TEST SET ARE HEAVY AND CAN CAUSE DAMAGE TO THE ENGINE.

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 98L36103002000 TEST SET - ENGINE BLEED: A.If the AIR SOURCE - REGULATED, FILTERED, DRY has a manometer: Do not install the primary regulator valve. Slowly pressurize the 98L36103002000 TEST SET - ENGINE BLEED to 200 psi (13.79 bar) with the AIR SOURCE - REGULATED, FILTERED, DRY shutoff valve and the manometer. B.If the AIR SOURCE - REGULATED, FILTERED, DRY has no manometer: Install the primary regulator valve. NOTE: The primary regulator valve will keep the pressure in limit in the 98L36103002000 TEST SET - ENGINE BLEED to 217 psi (14.96 bar).
3.On the 98L36103002000 TEST SET - ENGINE BLEED: Open the shutoff valve. Slowly pressurize the system from 10 psi (0.69 bar) to 90 psi (6.21 bar) with the regulator valve of the 98L36103002000 TEST SET - ENGINE BLEED.	On the 98L36103002000 TEST SET - ENGINE 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 98L36103002000 TEST SET - ENGINE BLEED: Depressurize the system with the regulator valve of the 98L36103002000 TEST SET - ENGINE BLEED.	On the TEST SET - ENGINE BLEED: The digital pressure gage shows 0 psi (0.00 bar).
