(b) If the impedance is correct (no short circuit and no open circuit):
- do a check of the impedance of the RTL ACT PWR ON signal between the pin AE/11A and the pin AC/3 of the FAC-1 rack connector, (Ref. ASM 22-68/02) and (Ref. ASM 22-67/01).
NOTE : The impedance must be more than 70 Ohms and not open
____
circuit.
1 If the impedance is not correct (< 70 Ohms or open circuit):
_
- remove the relay 13CC1 (open the circuit breaker 5CC1 before and close it after)
- do a check of the wiring of the RTL ACT PWR ON signal from the FAC1 to the relay 13CC1 (Ref. ASM 22-68/02).
a If the wiring is correct:
_
- replace the RELAY-RTL SYS1 (13CC1)
- install the above removed FAC-1 (Ref. AMM TASK 22-66-34-400-002).
2 If the impedance is correct (RTL ACT VALID and RTL ACT PWR ON
_
signals):
- do a check of the wiring of the 28VDC and GND at the RTLU (PWR SPLY) (Ref. ASM 22-68/02).
a If incorrect, repair the wiring.
_
b If correct, replace the RELAY-RTL SYS1 (13CC1).
_ If the fault continues:
- replace the FAC-1 (1CC1) (Ref. AMM TASK 22-66-34-400-002).
(2) If the fault continues:
- do a check and repair the remaining wiring from the FAC 1 (1CC1) to the rudder travel-limitation unit (4CC) (Ref. ASM 22-68/02).
B. If the test does not give the maintenance message AFS: FAC 1/RTL ACTR 4CC:
R (1) Replace the SENSOR-TAT, 1 (11FP1) (Ref. AMM TASK 34-11-18-000-001) R and (Ref. AMM TASK 34-11-18-400-001).
R (2) If the fault continues:
- do the operational test of the rudder travel limiting function (Ref. AMM TASK 22-61-00-710-001).
C. If the rudder does not move or stops before the rudder travel limit:
- replace the FAC-1 (1CC1) (Ref. AMM TASK 22-66-34-000-002) and (Ref. AMM TASK 22-66-34-400-002).
(1) If the fault continues:
- replace the electronic module of the rudder travel limitation unit (Ref. AMM TASK 27-23-51-000-002) and (Ref. AMM TASK 27-23-51-400-002).
(2) If the fault continues:
- replace the rudder travel limitation unit (4CC) (Ref. AMM TASK 27-23-51-000-001) and (Ref. AMM TASK 27-23-51-400-001).
(3) If the fault continues:
- do a check and repair the wiring of the RTL V1 and RTL V2 discretes from the FAC 1 (1CC1) to the rudder travel-limitation unit (4CC), (Ref. ASM 22-68/02).
D. Do the test given in Para. 3.B.
