REPAIRING AND NOT THROWING AWAY

In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

TUNTURI T10 TREADMILL - TUNTURI T20 TREADMILL SERVICE MODE ERROR CODES AND TROUBLE SHOOTING

TUNTURI T10 TREADMILL - TUNTURI T20 TREADMILL SERVICE MODE ERROR CODES AND TROUBLE SHOOTING


TUNTURI T10 TREADMILL - TUNTURI T20 TREADMILL

SERVICE MODE ERROR CODES AND TROUBLE SHOOTING 

The main electrical components of the Tunturi T10 and T20 are user interface (B02), power board (B44), motor (B18), lift motor (B25) speed sensor (B23), and power cable (B29).

SERVICE MENUS
Engineering Mode
1. Enter the engineering mode after switching the treadmill POWER ON by pushing first SELECT and then ENTER and hold buttons pressed simultaneously
2. The SPEED window shows the treadmill software version number, TIME window shows the software design year and DISTANCE window shows the design date in “MM.DD” format
3. Press ENTER to show LDU version number (Display control software)
4. Press ENTER to show ISP version number
5. Press ENTER to enter KM/MILE switch mode, 1 for KM, 0 for MILE
Switch between the KM or MILE setting by pressing SPEED +/- or ELEVATION +/-
6. Press ENTER to show total distance
7. Press ENTER to show total usage hours
8. Press ENTER to return to the normal mode
Testing Mode
1. Enter the testing mode after switching the treadmill POWER ON by pushing first SELECT and then SPEED DOWN and hold buttons pressed simultaneously
2. LED scanning mode for verifying display functionality
3. Press ENTER to scan DATA LINES to verify display functionality
4. Press ENTER to scan SACN LINES to verify display functionality
5. Press ENTER to scan LEDs to verify display functionality
6. 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)
7. 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’ to decrease speed value.
Press ENTER to repeat above test or SELECT and SPEED DOWN buttons simultaneously to return to the normal mode.
Lift motor calibration
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 gap between the upper end of the nut and the lift motor frame

7. Tighten the screws (A) and verify correct elevation by measuring
ERROR CODES
E1
The error will appear if the upper board cannot receive pulses from the speed sensor for 10 seconds.
Possible reasons:
Speed sensor not properly assembled, the distance between the magnet and the speed sensor should be less than 3mm.
Speed sensor cable disconnected
Meter cable has a poor connection at some point
Magnet missing from the front roller pulley
Front roller not rotating at all due to loose drive belt
Check the distance between the speed sensor and the flywheel and ensure that the speed sensor is properly attached to the motor frame. Check also speed sensor connections.
Error can be reset also by re-inserting the safety key.
E6
 The error message appears when voltage is being supplied to the lift motor but it doesn’t move.
Possible reasons:
Lift motor power cable disconnected
Lift motor electronically damaged preventing the movement
Error can be reset only by disconnecting the power cable.
E7
The values the lift motor potentiometer is sending are not within the preset limits.
If the readout from the potentiometer is 1 the software is not picking any signal from the potentiometer
Possible reasons:
Lift motor rotation sensor (potentiometer) cable disconnected
Lift motor rotation sensor has poor internal contact thus providing incorrect values
The second connection cable between user interface and lower board disconnected
The potentiometer has lost its calibration and rotated to minimum
If the readout from the potentiometer has lost its calibration setting and it differs from reference values adjust potentiometer to obtain correct value.
If the potentiometer has lost its position it can be lifted up after removing two attachment screws. Turn the potentiometer shaft to obtain correct setting and place the potentiometer back to the lift motor. To ensure that potentiometer maintains correct calibration setting a small amount of glue should be added to shaft before inserting it back to its counterpart.
Error can be reset also by re-inserting the safety key.
TROUBLESHOOTING
Treadmill is making knocking noise
The best way to start finding the root cause of the problem is to listen to the frequence of the noise. For example, the running belt seam overlaps a roller twice per revolution, should this be the frequency of the noise, the belt needs to be adjusted or replaced. If the noise has significantly higher frequency it is likely to be caused by a damaged front or rear roller bearing.
Adjust the rear foot to make the treadmill deck even with the floor
Heart rate readings are inaccurate
The motor wires needs to be wrapped through a ferrite ring and twisted around each other in order to prevent possible heart rate reading interference.
Home appliances, e.g. TV and mobile phone, and electric network can generate interference. Try using equipment in different environment.
Circuit breaker (10A) trips repeatedly
Check that the treadmill is running mechanically free
Check belt lubrication
If the wall outlet voltage is lower than normal the required current is higher and might cause the breaker to trip
Static electricity
Lubricate deck according to instructions in owner’s manual
Eliminate static electricity generators; user should not use nylon clothing and/or should try another pair of different type of training shoes
Ensure that the frame grounding wires are contacting steel by removing possible paint between the wire connector and frame
