 May 01/04 CES Failure of the Pedal Force Transducer Unit (74CE)

 1. Possible Causes
_______________
 - FTU-RUDDER PEDAL (74CE) R - C/B - RUDDER FTU (75CE)
 - wiring of the +28VDC signal from the pedal force transducer unit to the circuit breaker

 - wiring of the GND signal from the pedal force transducer unit to the ground

 - ground wiring of the pedal force transducer unit

 - wiring of the DGI 10 signal from the pedal force transducer unit to the first terminal block

Removal of the Rudder Pedal Force Transducer (74CE)
Installation of the Rudder Pedal Force Transducer
 (74CE)
BITE Test of the EFCS (Ground Scanning)

(1) Do the BITE test of the EFCS (ground scanning) (Ref. AMM TASK 27-96-00-740-001).
 4. Fault Isolation
_______________
 A. If the test confirm the fault:
 - replace the FTU-RUDDER PEDAL (74CE) (Ref. AMM TASK 27-92-27-000-001) and (Ref. AMM TASK 27-92-27-400-001).
 (1) If the fault continues: R - do the trouble shooting procedure (Ref. TASK 31-32-00-810-934) R related to the DGI 10 signal.

 (2) If the fault continues: R - replace the C/B - RUDDER FTU (75CE) (Ref. IPC 27920801).

 (3) If the fault continues: 
R  - do a check of the wiring of the +28VDC signal from the pedal force 
R  transducer unit to the circuit breaker (Ref. ASM 27-92/00). 
R  - do a check of the wiring of the GND signal from the pedal force 
R  transducer unit to the ground (Ref. ASM 27-92/00). 
R  - do a check of the ground wiring of the pedal force transducer unit 
R  (Ref. ASM 27-92/00). 
R  - do a check and repair the wiring of the DGI 10 signal from the 
R  pedal force transducer unit to the first terminal block (Ref. ASM 
R  27-92/00).
 B. Do the test given in para. 3.
