70 Installation Manual Upd | Kt

For sensor-based models (e.g., thermocouple or RTD input), the calibration steps assume you have a known reference source. The manual doesn’t explain how to simulate a sensor signal without extra equipment – leaving DIY users stuck.

| 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. | Kt 70 Installation Manual

The wiring diagrams, especially in the printed version, use 6-point type for terminal labels. If you have less than perfect vision, you’ll need a magnifying glass. The PDF version is better but zooming is awkward on a phone. Replace throttle

| Terminal | Output Type | Connection | |----------|-------------|-------------| | 8 & 9 | Relay (SSR/Contactor) | 8 = NO, 9 = COM | | 8 & 10 | 4-20mA current | 8 (+), 10 (–) | | 8 & 11 | 0-10V voltage | 8 (+), 11 (–) |
