R **ON A/C 001-049, 051-099, 101-105, 151-199, 201-214,
A. If the test gives the maintenance message:
ELAC 1 COM OR WIRING TO L B ELEV SERVO VLV 34CE3
- replace the ELAC-1 (2CE1) (Ref. AMM TASK 27-93-34-000-001) and (Ref. AMM TASK 27-93-34-400-001).
(1) If the fault continues:
- replace the servovalve (Ref. AMM TASK 27-34-51-000-008) and (Ref. AMM TASK 27-34-51-400-003).
(2) If the fault continues:
(a) Do a check of the wiring of the L ELEV SV (ANO 1) signal from the ELAC 1 (2CE1) COM part, pins AB/2E, 2D to the ELAC 1 COM part, pins AA/2H, 2G (Ref. ASM 27-93/07):
- if there is continuity see Para. (b)
- if there is no continuity repair the above wiring.
(b) Do a check of the wiring from the ELAC 1 (2CE1) COM part to the MON part from pins AA/2J, 2K to pins AD/3A, 4A (Ref. ASM 27-93/07):
- if there is continuity see Para. (c)
- if there is no continuity repair the above wiring.
(c) Do a check of the wiring from the ELAC 1 (2CE1) MON part, pins AD/3C, 4C to the first terminal block (Ref. ASM 27-93/07).
- if there is continuity see Para. (d)
- if there is no continuity repair the above wiring.
(d) Do a check of the wiring of the LVDT SV SPLY signal, from the servocontrol (34CE3) to the first terminal block (Ref. ASM 27-93/07).
- if there is continuity see Para. (e)
- if there is no continuity repair the above wiring.
(e) Do a check of the wiring of the LVDT POS (ANI 3-1) signal, from the ELAC 1 (2CE1) MON part to the servocontrol (34CE3) (Ref. ASM 27-93/07).
- if there is continuity see Para. (3)
- if there is no continuity repair the above wiring.
(3) Replace the SERVO CTL-L ELEVATOR, OUTBD B (34CE3) (Ref. AMM TASK 27-34-51-000-001) and (Ref. AMM TASK 27-34-51-400-001).
R **ON A/C 106-149, 215-299, 301-399, 401-499,
A. If the test gives the maintenance message:
ELAC 1 COM OR WIRING TO L B ELEV SERVO VLV 34CE3
- replace the ELAC-1 (2CE1) (Ref. AMM TASK 27-93-34-000-001) and (Ref. AMM TASK 27-93-34-400-001).
(1) If the fault continues:
(a) Do a check of the wiring of the L ELEV SV (ANO 1) signal from the ELAC 1 (2CE1) COM part, pins AB/2E, 2D to ELAC 1 COM part pins AA/2H, 2G (Ref. ASM 27-93/07):
- if there is continuity see Para. (b)
- if there is no continuity repair the above wiring.
(b) Do a check of the wiring from the ELAC 1 (2CE1) COM part to the MON part from pins AA/2J, 2K to pins AD/3A, 4A (Ref. ASM 27-93/07):
- if there is continuity see Para. (c)
- if there is no continuity repair the above wiring.
(c) Repair the wiring from the ELAC 1 (2CE1) MON part, pins AD/3C, 4C to the first terminal block (Ref. ASM 27-93/07).
**ON A/C ALL
B. Do the test given in Para. 3.
Loss of the Signal of the Left Blue Elevator-Servocontrol Servovalve by the ELAC 1
1. Possible Causes
_______________
- ELAC-1 (2CE1)
- XDCR UNIT-ELEV POS, L (49CE1)
- SERVO CTL-L ELEVATOR, OUTBD B (34CE3)
- servovalve
- wiring of the POS XDCR (ANI 3-1) signal from the ELAC 1 (2CE1) to the first terminal block
- wiring of the POS XDCR MON signal from the transducer unit (49CE1) to the ELAC 1 (2CE1)
