NOTE: If ground or other harness wire connections are broken or disconnected, the ELT is still capable of automatic activation. However, the remote switch may be incapable of resetting the ELT or operation may not be indicated on the remote switch LED.
2.7.1 Harness Wiring – Remote Switch End
1) If an Artex remote switch is already installed, verify contacts and ground and proceed to “Harness ELT End”. For new installations, strip about 0.150” (3.8mm) of insulation from the ends of each of the wires of the cable harness.
2) Crimp a female receptacle (Artex P/N 151-6628) onto each wire using crimp tool (Molex # 0638191300, Waldom or Sargent # HTR-1719C). Insert wires into appropriate positions of housing (Artex P/N 151-5009) per Figure 9.
Information: Molex pin extraction tool is # 11-03-0002
3) Fabricate a fused power supply lead that connects to either pin 1 (+14V) or pin 3 (+28V). Crimp a female receptacle (Artex P/N 151-6628) onto the connector end.
2.7.2 Harness Wiring – ELT End
1) Cut a ground wire to length that will connect the 15-pin D-sub mating connector (Artex P/N 150-1130) to ground. Cut a wire for the buzzer that will connect to the D-sub.
2) From connector back-shell (Artex P/N 150-1127) select grommet from grommet ‘tree’ that fits firmly around cable harness and the ground & buzzer wires. Slip grommet over these wires with the smaller diameter shoulder towards the connector. Slide it away from harness end so that it does not interfere when soldering the connector.
3) Solder a short jumper from pin 5 to pin 12 on the D-sub.
4) Solder the cable harness wires, buzzer wire and ground wires to D-sub pins. Pin 7 may require the attachment of two wires. It may be easier to splice wires, and then connect a single wire to the pin. Consult AC 43.13.
5) On a flat surface, fit the connector w/attached harness into one-half of connector housing positioning grommet so that it fits into recess at end of connector housing.
6) Install rectangular bracket washers onto thumbscrews, and then insert thumb screws into lower housing half.
7) Fit remaining housing half onto lower section taking care to align thumb screws, grommet and connector. Position the bracket washers outside of housing. Screw housing together using the long, fully-threaded screws and nuts supplied.
8) Extra screws and strain relief supplied with housing kit are not used.
2.7.3 Connect Harness
1) With the harness installed, insert the crimped end of the fused power supply link into the appropriate position of the 9-pin remote switch housing. This will be either pin 1 (+14V system) or pin 3 (+28V system). Plug this end into the remote switch.
2) Install the ELT in its mounting tray, securing with the Velcro strap.
3) Place 2 each of the 850-0814 sealing strips (provided with install kit 455-7423) into ELT 15-pin D-sub connector. Plug mating D-sub from harness into ELT. 中國航空網 www.k6050.com 航空翻譯 www.aviation.cn 本文鏈接地址：DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL ME406P ELT(18)
