T6 t7 error in lift motor

My son kept elevating deck and the screw has come out of the threaded boss on the bottom side.
Switch on and no life from the lift motor, no sound , then errors.
I see the trim pot inside and have moved to try and fool into thinking that it hasn't gone over limit but all way CW and all way CCW makes no difference
Am a mechanical engineer so don't want to fix it myself.
Is the control card seeing wrong volts from trim pot,
It seems odd that it doesn't reset itself after power off and at least try and power the lift motor.
No smell or any evidence of burn out , and it failed unscrewing (coming out) not bottoming out at 0 elevation.HELP PLEASE.

That potentiometer may finally gave up the ghost or the unit may need to re calibrated but first it needs mechanically put back together I would call Accell fitness of North America they are the distributors of Tunturi Treadmills and should have the technical data to help in the process.

I need ang diagram for hobart mixer 9 out wire T1/T2/T3 AND T4/T5/T6, T7/T8/T9 which is the right partner of t1/t2/t3???


Having 9 wires means it is a 3 phase motor.
For 220 to 240 Volts - L1, T1 and T7 go together. L2, T2 and T8 go together. L3, T3 and T9 go together. T4, T5 and T6 go together.

For 440 to 480 Volts - L1 and T1 go together. L2 and T2 go together. L3 and T3 go together. T4 and T7 go together. T5 and T8 go together. T6 and T9 go together.

My Tunturi Treadmill ramp is stuck in the top elevation position and will not run. I get a "Auto Syncing" message, but the machine will not run. Have tried unplugging etc, but it will not exit the mode...


Enter the testing mode after switching the treadmill POWER ON by pushing first ‘SELECT’ and then ‘SPEED DOWN’ and hold buttons pressed simultaneously.
LED scanning mode for verifying display functionality Press ‘ENTER’ to scan DATA LINES to verify display functionality Press ‘ENTER’ to scan SACN LINES to verify display functionality Press ‘ENTER’ to scan LED’s to verify display functionality After pressing ‘ENTER’ the TIME window shows “test” and the keypad functionality can be tested (the value displayed changes when a button is being pressed) Press ‘ENTER’ to enter IO mode (TIME display shows lift motor potentiometer value, SPEED reads speed from speed sensor and DISTANCE shows heart rate pulse) Press ‘START’ to test lower board relay (a “click” sound) and then press ‘ELEVATION UP’ for 2 seconds to increase the elevation to 8%. Press ‘ELEVATION DOWN’ to decrease the elevation to minimum percentage 0% Press ‘SPEED UP’ to increase speed value and ‘SPEED DOWN’ toto decrease speed value. Press ‘ENTER’ to repeat above test or ‘SELECT’ and ‘ SPEED DOWN’ buttons simultaneously to return to the normal mode
The lift motor calibration is done manually by following the following steps: 1. Drive the lift motor to 0% from user interface (inclination display must be 0%) 2. Switch off the treadmill and unplug the power cable 3. Remove motor cover 4. Fold up the running deck 5. Loosen two screws (A) attaching the lift motor nut (B) to the incline frame 6. Adjust the lift motor nut (B) so that there is 9 mm (.358 in ) gap between the upper end of the nut and the lift motor frame Tighten the screws (A) and verify correct elevation by measuring Adjusting lift motor to 0% position 2.76in 12% position 9.646 in measurement taken from floor to bottom of motor compartment frame.

In life fitness next generation operation elevation is not working.!What is the problem?


It will be one of three things: #1 faulty Wax/Lift circuit board that controls the lift motor,#2 the motor itself, or #3 a faulty home switch, which is the white plastic switch in the base of the machine which senses the home position or zero degrees elevation.
