3. In this summary we are going to cover basic troubleshooting techniques used in the industry to diagnose and repair True Fitness treadmills more quickly and efficiently Current True treadmills use 3 types of drive system 1 AC DRIVE WITH SMART CARD INTERFACE TCS Series and TLC1100 Upper gt E Ius Board Board on Board e Motor The new TCS Series treads with the smart card system utilize a digital signal for both command and feedback This signal cannot be tested with normal field equipment Diagnostics must be done using the status lights on both the lower control board and smart card 2 DC DRIVE WITH SMART CARD INTERFACE TES900 TLC900 and TPS850 This system is basically the same as the above AC smart card system however no motor transmit and receive LEDs are lit on the DC smart card 3 DC DRIVE All TPS series except TPS850 Z5 series This system is the same as all our traditional DC drive systems Proprietary amp Confidential Tread Service Manual July 201 1 9 TRUE Fitness Technology Inc ELEVATION SYSTEM OVERVIEW The elevation systems on all True Treadmills use AC Alternating Current motors to lift the treadmill to the desired elevation This system uses a command from the upper control board that is sent to the lower board which in turn sends an AC voltage to the windings of the elevation motor There are two sets of windings on the AC incline motor one for each direction of motor movement The
