Kt 70 Installation Manual

The KT 70 should be mounted in the radio stack within clear view of the pilot. While it features highly efficient solid-state circuitry, stacking multiple pieces of avionics creates tight thermal pockets. The manual emphasizes checking for or ensuring adequate passive airflow spacing to protect the internal power supply components. 2. Mounting Rack Deployment

Connect to a compatible blind encoder (e.g., KEA 130A) or directly to an Air Data Computer (ADC).

: Following any installation or modification, the system must undergo a formal certification test. In the United States, this must comply with 14 CFR Part 43, Appendix E and F , which verifies altitude reporting accuracy and transponder performance.

If the aircraft features a DME or a second transponder, connect Pin 35 to the mutual suppression bus. This prevents the KT 70 from transmitting while other RF equipment is pulsing, protecting the receiver front-end from damage. 4. Antenna Installation and Coaxial Routing Kt 70 Installation Manual

: Aircraft Lighting Dimmer Bus (matches aircraft voltage).

2.4 Amps maximum at 14 VDC; 1.2 Amps maximum at 28 VDC. Certifications: TSO-C112 (Mode S airspace compliance).

Secure the sleeve to the instrument panel side rails using appropriate rivets or screws. The KT 70 should be mounted in the

The document is rated highly (approx. 88%) by users on professional technical platforms like for its utility in maintenance and system engineering.

The following are the general steps for installing the KT 70 system:

| Error Code | Meaning | Solution | |------------|---------|----------| | | Throttle fault (stuck or broken) | Check throttle voltage (0.8-4.2V). Replace throttle. | | E003 | Motor hall sensor failure | Test hall wires (yellow/green/blue). Replace motor harness. | | E004 | PAS/T_Sensor fault | Check PAS connection, magnet gap (2-3mm). | | E005 | Brake cutoffs engaged | Release brakes. If constant, short the brake sensor plugs. | | E006 | Battery low voltage | Charge battery. Check undervoltage protection setting (P3). | | E007 | Overcurrent protection | Reduce assist level. Check controller current limit (C14). | | E008 | Throttle not at zero at startup | Do not hold throttle when powering on. | | E010 | Controller communication error | Check TX/RX pins, cable continuity. Replace controller or display. | In the United States, this must comply with

Standby (SBY), Test (TST), Ground (GND), ON, and Altitude (ALT). 2. Installation Guidelines

A: Check P2 setting. For external speed sensor, ensure magnet passes sensor within 5mm.

The BendixKing KT 70 (AlliedSignal) Installation Manual (Part #006-00673-0002) outlines installation, system interconnect, and calibration procedures for the panel-mounted Mode S transponder. It covers technical specs including 11–33 VDC power, 200W output, and TSO compliance. For a full copy, see the Aircraft Maintenance Manuals listing .
