- Page 13 AUSES Table of Contents Motor Control Board (MCB) failure T101-05, T101-07, TR5, TR3 The MCB takes electricity from the outlet and converts it to power for the console, as well as translates control signals from the console to drive the belt & incline motors. Issues caused by MCB faults can present in many ways, from belt speed control issues, incline issues, console power issues, or causing the treadmill or electrical panel breaker to open.
- Page 14 AUSES Table of Contents Damaged console cable/console cable too short (after incline) T101, TR5, TR3 The console cable is the link between the console and MCB, carrying console power and control signals between the different parts of the treadmill. The console cable can be damaged in numerous ways: pinched or crushed by incorrect routing, kinked around sharp bends, or knicked when a fastener is tightened into it, for example.
- Page 15 AUSES Table of Contents To inspect the console cable: 1. Disconnect power and remove the motor cover. Locate the socket on the MCB where the console cable connects and ensure that connection is secure. 2. Trace the console cable along its routing, paying special attention to any irregularities in the shape or size of the cable.
