Kt 70 Installation Manual !exclusive! ❲2026 Update❳
Secure the controller to the panel or DIN rail. Leave slack in wires to avoid pulling terminals.
Connect to a compatible blind encoder (e.g., KEA 130A) or directly to an Air Data Computer (ADC).
Turn on the avionics master. Verify that the KT 70 powers up, displays its self-test sequence, and does not trip the circuit breaker. Check that the display dimming responds correctly to the aircraft panel lighting bus. Kt 70 Installation Manual
Ensure a clean, unpainted metal-to-metal contact with the skin.
Perform a static system leak check if the encoder was disturbed. Secure the controller to the panel or DIN rail
Use 20 AWG MIL-W-22759/16 wire for power (Pins 1 and 2) and ground (Pins 3 and 4). Install a 5-Amp circuit breaker for 14V systems or a 3-Amp circuit breaker for 28V systems.
To report altitude to Air Traffic Control (ATC) in Mode C or Mode S, the KT 70 must be linked to an altitude encoder or encoding altimeter. The manual maps out the standard . Technicians must exercise extreme care when crimping and routing these parallel data lines to avoid data corruption, which causes "ghosting" or incorrect altitude readouts on ATC radar scopes.

| Pin Number | Wire Color | Signal Function | Notes | |------------|------------|----------------|-------| | 1 | Red | Battery+ (VCC) | Typically 24-48V | | 2 | Blue | RX (Receive data) | From display to controller | | 3 | Black | Ground (GND) | Common negative | | 4 | Green | TX (Transmit data) | From controller to display | | 5 | Yellow | Controller lock (power switch) | Some versions use for lights |
The ARINC 429 lines (Pins S and T) must be a twisted, shielded pair. Terminate the shield braid directly to the aircraft chassis ground at the backplate entry point, keeping the unshielded leads shorter than 3 inches. 3. RF Antenna System Installation
