R A. Test
R (1) Do the ECB self test (Ref. AMM TASK 49-00-00-710-009).
R NOTE : If the self test of the ECB gives a maintenance message, do
____ R the related trouble shooting first before you continue with R this test.
R (2) Get access to the AIDS parameters (ALPHA CALL UP) (Ref. AMM TASK 31-R 36-00-740-008).
R (3) Start and operate the APU (Ref. AMM TASK 49-00-00-860-008).
R (4) On overhead panel 35VU, make sure that the APU GEN p/bsw is released
R (APU GEN off).
R (5) Examine and record the indications of the APU system page on the
R lower ECAM display unit and the AIDS parameters on the MCDU for the
R subsequent conditions.
R Record the trend of the EGT during change of APU running state.
R NOTE : On the MCDU, you can read these AIDS parameters:
____ R - IGV (APU Inlet Guide-Vane position; parameter 7A.1.130.01), R - WB (APU Corrected Bleed-Air Flow; parameter 7A.1.123.01), R - ADW1 (APU Discrete Word - Information regarding APU R operating status; parameter 7A.1.37.01),
R . ADW Alpha code = ADW1 for SAGEM FDIMU
R . ADW Alpha code = APUDSW1 for TELEDYNE FDIMU
R - PD (Main Engine Precooler-Inlet Air-Pressure),
R . Parameter 06F.1.143.01 for Engine 1
R . Parameter 06F.2.143.10 for Engine 1
R . Parameter 06F.1.142.01 for Engine 2
R . Parameter 06F.2.142.10 for Engine 2
R - LCIT (APU Inlet Temperature; parameter 7A.1.123.01),
R - PT (Bleed Air Pressure; parameter 7A.1.166.01).

R NOTE : On the APU page of the lower ECAM display unit, you can____
R monitor:
R - TAT (Total Air Temperature in deg. C)
R - GLA (APU Generator Load in %)
R - EGT (APU Exhaust Gas Temperature)
R (a) APU in RTL (Ready-to-Load) running state:
R - on overhead panel 25VU the blue AVAIL legend in the APU START
R p/bsw is on;
R 1_ Record the applicable parameters (Ref. TABLE A).
R (b) APU in 2 pack ECS running state (PACK 1 and 2):
R - on overhead panel 30VU the APU BLEED p/bsw is pushed to ON;
R - on overhead panel 30VU the PACK 1 p/bsw is pushed (OFF legend
R is off);
R - on overhead panel 30VU the PACK 2 p/bsw is pushed (OFF legend
R is off);
R 1_ Record the applicable parameters (Ref. TABLE A).
R (c) APU in MES (Main Engine Start) running state (ENG1):
R 1_ Do the dry motoring of the engine 1 (Ref. AMM TASK 71-00-00-
R 710-001);
R 2_ Record the applicable parameters (Ref. TABLE A).
R (d) APU in MES (Main Engine Start) running state (ENG2):
R 1_ Do the dry motoring of the engine 2 (Ref. AMM TASK 71-00-00-
R 710-001);
R 2_ Record the applicable parameters (Ref. TABLE A).
R (6) Shutdown the APU (Ref. AMM TASK 49-00-00-860-009).
R B. Parameter Values during different APU running states.
