Week 2 :Testing and Troubleshooting of ELAC

We are asked to test and troubleshoot the testing trays before going to be used in the production line. There are total of 5 testing trays :

• ELAC         -Elevator and Aileron Computer
• SEC            -Spoiler Elevator Computer (Airbus)
• FMGC1      -Flight Management Guidance Computer
• FMGC2      -Flight Management Guidance Computer
• FAC            -Flight Augmentation Computer (autopilot)

Testing tray for ELAC-Elevator and Aileron Computer( Airbus A320). 

ADL -   Airborne Data Loader

 SDL -  Surface Data Logging

 

This is the side where we insert the ELAC unit.

 

This is the side where we power up it by using 28V DC power supply and the MUX cable.

 

This is the ELAC 28V DC power supply cable.
We need to check the connection of it with the schematic diagram provided.

 

This is test result of ELAC 28V DC power supply cable.

Schematic diagram for ELAC testing tray

We have done the point to point checking by using the calibrated digital multimeter

(DMM) with Continuity Test

.

 

After we checked every points of the machine,we found out that some of the wires are connected wrongly.Therefore,we are asked to correct it by re-soldering to the correct point provided by the schematic diagram.

. 

 

This is the testing result for ELAC.

We need to key in to a formal report together with the result of power cable which we need to submit to company after we have done the checking of the tray and the cable.
