Programming of the Identification Plug (Push-Pull Design) for DAC engines [CFMB]

TASK 73-21-90-860-001-A-01
Programming of the Identification Plug (Push-Pull Design) for DAC engines

1. Reason for the Job
This task is only applicable for DAC engines.
To give a correct configuration of the programmable inputs into the identification plug. For programmable inputs, push-pull pins must be positioned to give a configuration set-up related to a specific engine configuration.
The engine thrust cannot be changed. This parameter is given by the Part Number of the Identification Plug (Ref CFM SB 72-0003).

C. Programming of the Configurable Inputs to the Identification Plug

NOTE: This procedure is applicable for the aircraft equipped with PRE FADEC STANDARD 5BL.

A specific set-up of push-pull contacts gives the specific engine configuration. The state of the contact is either "Pull" or "Push".

NOTE: The push-pull pin has 2 catches corresponding to 2 contact positions, a color mark (black adhesive strip) indicates these two positions, one contact position is not visible in the "push" position and the other is visible in the "Pull" position. A mechanical stop on the pin limits the travel of the pin.

NOTE: It is highly recommended to do the following procedure in a closed area to avoid contamination of the electric contacts inside of the connector.

(1) Remove the cap located at the rear of the identification plug:
(a) Cut the safety wire securing the body to the identification plug.
(b) Unscrew the cap from the identification plug body using a PLIERS - NOSE, SOFT, LONG.
(c) Do a check of the O-ring installed on the body. If damaged, discard it and replace it by a new one.
(2) Pull all the pins against their stop.
(3) Programming of the Engine configuration, System configuration and Control parity configuration:

The programming set-up of the engine identification plug must be installed following the table hereunder based on the specific engine configuration:

(b) Position the push-pull pin refers to the configuration table above using a PLIERS - CONNECTOR, JAW, SOFT.
(6) Programming of the Spare configuration:

NOTE: Pins No.3 specifies Spare configuration for CFM56-5BX/2P engines.

(a) Location of the push-pull pin to be configured.
Detail E.
(b) Position the push-pull pin refers to the configuration table above using a PLIERS - CONNECTOR, JAW, SOFT.
(7) Make sure that the configured Push-Pull links agree to the applicable engine configuration.
(8) Make sure that the black strip is not visible on the pushed pins.
(9) Do a check of the pushed and pulled pins:

CAUTION: PUSH-PULL PINS NOT PROPERLY SET AGAINST THEIR STOP MAY AFFECT THE CODING OF THE ENGINE IDENTIFICATION CONNECTOR AND TRIGGER A CFDS FAILURE MESSAGE/ECAM WARNING.

(a) Make sure that all pushed pins are fully pushed against their stop.
(b) Make sure that all pulled pins are fully set against their stop.
(10) Install the cap on the identification plug:
(a) Screw the cap at the rear of the identification plug.
(b) Manually, do 3 hand tightening of the body until the color strip, then get the mechanical stop (unscrew a quarter of a turn between each tightening) using a PLIERS - CONNECTOR, JAW, SOFT.
(c) Safety the cap with the plug body with CP8001lockwire 0.032 in. (0.8 mm) dia..
(11) Remove the identification plug from the Antagonistic connector (locally manufactured).
(12) Install the identification plug on the engine, (Ref. AMM TASK 73-21-90-400-002).

Subtask 73-21-90-710-056-A ** ON A/C NOT FOR ALL

E. Do this test:

NOTE: This procedure is applicable for the aircraft equipped with ALL FADEC STANDARD.

NOTE: This test is mandatory to make sure that the configured identification plug inputs are correctly read through the ECU and agree with the applicable engine configuration.

(1) On the left or right MCDU, do this check:
(a) Get access to the screen of the SYSTEM REPORT/TEST ENG (Ref. AMM TASK 31-32-00-860-012).
(b) Push the line key adjacent to the FADEC1(2) A(B): The ENGINE MAIN MENU page comes into view.
(c) Do a functional test of the ECU (Ref. AMM TASK 73-21-60-720-040).
(d) Read the LRU IDENTIFICATION Report of the engine 1(2) (Ref. AMM TASK 73-21-60-740-006).

NOTE: The LRU identification check is only necessary on one of the ECU channels A or B.

1 Push the line key adjacent to the LRU IDENT indication: CHANNEL A(B) page comes into view.
2 Read the data that comes on the MCDU screen and check for consistency with the actual engine configuration:
a Engine thrust rating and type:

These inputs are available on the engine identification plate.

NOTE: The engine thrust rating is available for engines POST CFM SB 73-0039.

NOTE: The engine type is available for engines POST CFM SB 73-0033.

NOTE: The engine thrust rathing must be the same as on opposite engine and agree with the Aircraft Model.

b "LRU PART NO" (ECU Part Number):

The P/N is available on the ECU identification plate.

c "N1 TRIM":

The N1 trim level (0 through 7) is available on the engine identification plate.

d "BUMP" option: must read "Y" or "N".
e "PMUX" option:

PMUX engine (4 hoses connected to the ECU) must read "Y"
Non PMUX engine (2 hoses connected to the ECU) must read "N".

f "CONFIG" (system configuration): Do a check the engine EDS (Engine Data Submittal) for reference:

"TBV" applies to CFM56-5BX/2P equipped with a TBV Valve,
"NACTB" applies to CFM56-5BX/2P equipped with a NACTB Valve.

g "DAC CONFIG" (DAC hardware configuration): Do a check the engine EDS (Engine Data Submittal) for reference:

"2" = DAC FN (DAC 1 Combustor with DAC 2 fuel nozzles)
"3" = DAC 2 COMB (DAC 2 Combustor with DAC 2 fuel nozzles).

h "ENGINE" (Engine Serial Number):

Make sure the S/N displayed on the screen is the same as the one written on the Engine identification plate.

i If "CCNIDP" is displayed on the screen:

NOTE: "CCNIDP" is only displayed on the screen for engines POST CFM SB 73-0113.

If standard nozzle configuration is installed "CCNIDP" must be read N.
If Core chevron nozzle configuration is installed "CCNIDP" must be read Y.

NOTE: Standard nozzle configuration is identified by a smooth conical exit surface
Core chevron nozzle configuration is identified by 8 chevrons (triangular) round circumference of the exit surface (SB RA32078-118).
