Operational Test of the Ignition System without CFDS [CFMI]

TASK 74-00-00-710-040-A-01
Operational Test of the Ignition System without CFDS

WARNING: DO NOT DO THIS TEST IN THESE CONDITIONS:

DURING THE AIRCRAFT REFUELING
WHEN THE AIRCRAFT IS NEAR BUILDINGS
WHEN OTHER AIRCRAFT ARE IN THE JET EXHAUST AREA FOR GROUND IDLE
WHEN THE AIRCRAFT IS IN THE HANGAR.

MAKE SURE THAT NO PERSONS OR EQUIPMENT ARE IN THE JET EXHAUST AREA WHEN YOU DO THE GROUND IDLE OF THE APPLICABLE ENGINE. IF YOU DO NOT OBEY THESE PRECAUTIONS, INJURY TO PERSONS AND DAMAGE EQUIPMENT CAN OCCUR.

WARNING: BEFORE YOU START WORK ON THE IGNITION SYSTEM, MAKE SURE THAT THE IGNITION EXCITERS ARE DE-ENERGIZED FOR A MINIMUM OF FIVE MINUTES. ALSO DO NOT TOUCH THE ELECTRICAL CONTACTS. THE IGNITION SYSTEM VOLTAGE IS VERY HIGH, AND THE IGNITION EXCITERS CAN HAVE AN ELECTRICAL CHARGE EVEN WHEN NOT ENERGIZED. IF YOU DO NOT OBEY THESE PRECAUTIONS, INJURY CAN OCCUR.

D. Aircraft Maintenance Configuration
(1) On the maintenance panel 50VU:

Release the ENG/FADEC GND PWR/1(2) pushbutton switch. The ON legend of this pushbutton switch comes on.

(2) On the ENG panel 115VU, make sure that:

The ENG/MODE/CRANK/NORM/IGN START selector switch is set to NORM.
The ENG/MASTER 1(2) control switch is set to OFF.

(3) On the overhead control and indication 22VU:

Make sure that the ON legend of the ENG/MAN START/1(2) pushbutton switch is off (the pushbutton switch is released out).

(4) On the HYD/FUEL panel 40VU:

Make sure that the OFF legends of all the FUEL/PUMPS pushbutton switches are on (the pushbutton switches are released).

4. Procedure
Subtask 74-00-00-710-056-A ** ON A/C NOT FOR ALL

WARNING: MAKE SURE THAT THE INLET PRESSURE INDICATION FOR THE STARTER VALVE IS ZERO BEFORE YOU PUSH THE ENG/MAN START/1 (2) PUSHBUTTON SWITCH.

A. Test

ACTION	RESULT
1.On the ENG panel 115VU: Set the ENG/MODE/CRANK/NORM/IGN START selector switch to IGN START.	On the upper ECAM display unit: The primary engine parameters come into view. On the lower ECAM display unit: The IGN indication and the starter valve symbols come into view. NOTE: Ignore the warnings that occur during the procedure that follows.
2.On the OVERHEAD CTL & IND panel 22VU: Push the ENG/MAN START/1(2) pushbutton switch.	The ON legend of this pushbutton switch comes on.
3.On the ENG panel 115VU: Set the ENG/MASTER 1(2) control switch to ON.	On the engine 1(2): Make sure that the two igniter plugs make a noise. On the lower ECAM display unit, on the ENGINE page: The A and B indications come into view.
4.On the OVERHEAD C/B panel 49VU: Open the circuit breaker 1JH.	On the engine 1(2): Make sure that only one igniter plug makes a noise.
5.On the REAR C/B panel 121VU: Open the circuit breaker 3JH1 (3JH2).	On the engine 1(2): Make sure that there is no noise from the two igniter plugs.
6.On the OVERHEAD C/B panel 49VU: Close the circuit breaker 1JH.	On the engine 1(2): Make sure that only one igniter plug makes a noise.
7.On the REAR C/B panel 121VU: Close the circuit breaker 3JH1 (3JH2).	On the engine 1(2): Make sure that the two igniter plugs make a noise.
8.On the ENG panel 115VU: Set the ENG/MASTER 1(2) control switch to OFF.	On the engine 1(2): Make sure that there is no noise from the two igniter plugs.
9.On the OVERHEAD CTL & IND panel 22VU: Release the ENG/MAN START/1(2) pushbutton switch.	The ON legend of this pushbutton switch goes off. On the lower ECAM display unit, on the ENGINE page: The A and B indications go out of view.
10.On the ENG panel 115VU: Set the ENG/MODE/CRANK/NORM/IGN START selector switch to NORM. NOTE: The ECU stays electrically supplied for 5 minutes after you set: the ENG/MASTER 1(2) control switch to OFF. The ENG/MODE/CRANK/NORM/IGN START selector switch to NORM. NOTE: You can clear the WARNING messages that come on when you do this procedure. To do this set to ON and OFF the ENG/MASTER 1(2) control switch .

5. Close-up
