KT 70 Installation Manual

Chapter 1: What’s in the Box? (Unboxing the Kt 70 System)

Before reading the installation manual, verify your package contents. A standard Kt 70 retail kit includes:

  1. KT-70 LCD Display Unit – The main interface with backlit LCD screen and buttons (Power/Up/Down/Info).
  2. Waterproof Harness Cable – Usually 1T2 or 1T4 connector (5-pin female Julet/Higo).
  3. Mounting Bracket – Handlebar clamp (compatible with 22.2mm/25.4mm bars).
  4. Rubber Shims – For secure handlebar mounting.
  5. Velcro Cable Ties – For cable management.
  6. (Optional) Extension Cable – For long-tail or cargo bikes.

⚠️ Warning: If you purchased a generic kit, confirm that the display is compatible with your specific KT controller model (e.g., KT36/48ZWSRL, KT24/36SVPR). The Kt 70 works with most KT sine wave controllers. Kt 70 Installation Manual

Step 3: Connect Throttle (If used)

A throttle connects to the controller’s throttle input. The Kt 70 will show throttle percentage in real time. KT 70 Installation Manual Chapter 1: What’s in the Box

Monthly Checks

  • Retighten terminal screws (vibration loosens them).
  • Clean dust from vents using dry compressed air.
  • Verify alarm functionality by forcing a setpoint overrun.

Safety and Warnings

  • Qualified personnel only: Installation and servicing must be performed by trained technicians.
  • Disconnect power before making any electrical connections.
  • Lockout/tagout procedures required.
  • Use personal protective equipment (PPE): gloves, eye protection, insulated tools.
  • Rated components only: follow listed voltage and current ratings.
  • Environmental limits: install indoors in a dry, dust-free environment unless the unit is rated for outdoor use.

4. Testing and Certification

Once installed, the job isn't done until the unit is tested. The manual outlines the functional test procedures required for FAA Form 337 return-to-service sign-off. KT-70 LCD Display Unit – The main interface

  • Mode C Verification: You must verify altitude reporting accuracy against a known pressure altitude source.
  • Squawk Code Logic: Testing the ident function and code entry logic.
  • Transmit Power: While typically a shop function, the manual references the required transmit power output (minimum 125 watts nominal).

Pros

  • Basic Wiring Diagram Included: The manual usually contains a clear, simplified wiring schematic showing the main harness, power, ground, and output wires (e.g., door lock triggers, turn signals).
  • Pinout Table: Most versions include a pin-by-pin description of the control module, which is helpful for identifying wire functions (e.g., red = +12V constant, black = ground, white = parking light output).
  • Safety Warnings: Basic cautions about disconnecting the battery, avoiding short circuits, and proper fuse ratings are typically present.

Electrical Connections

  1. Confirm main power is OFF and verified with a multimeter.
  2. Open the terminal cover.
  3. Connect ground (protective earth) first to the designated terminal. Ensure low impedance connection.
  4. Connect neutral and live (L/N) to the correct terminals per the unit label.
  5. Tighten terminal screws to specified torque (typically 0.5–1.0 Nm for small terminals; verify label).
  6. For units with separate control power or battery, connect per wiring diagram.
  7. Route control and power cables separately to minimize interference; use ferrite chokes on data lines if required.
  8. Refit terminal cover.
