TUNTURI  Pliant Delta  -  Sigma

SERVICE MENUS
1 Enter the engineering mode after switching the treadmill POWER ON by pushing first „SELECT‟ and then „SPEED + and hold buttons pressed simultaneously approximately 5 seconds
Engineering Mode
2. Sigma. The SPEED and DISTANCE windows shows the treadmill software version numbers, CALORIES and INCLINE/PULSE windows show the software design year and TIME window blank
1. Delta. The SPEED window shows the treadmill software version number, TIME window shows the software design information
2. Press „ENTER‟ to show LDU version number (Display control software)
3. Press „ENTER‟ to show ISP version number
4. 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
+/-** Sigma will toggle between 0 and 1 – Delta will not. Delta + = 1, -= 0
5. Press „ENTER‟ to show total distance
6. Press „ENTER‟ to show total usage hours
7. Press „ENTER‟ to return to the normal mode
TEST MODE
1. Enter the testing mode after switching the treadmill POWER ON by pushing first „SELECT‟ and then „START‟ and hold buttons pressed simultaneously Testing Mode
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 LED‟ s to verify display functionality
6. After pressing „ENTER‟ the INCLINE/PULSE window shows “test” and the keypad functionality can be tested (the value displayed changes when a button is being pressed)
7.Delta After pressing „ENTER‟ the INCLINE/PULSE window shows “P” and the heart rate functionality can be tested (the value displayed changes when the pulse increases)
8. Press „ENTER‟ to enter IO mode
Sigma:(INCLINE/PULSE display shows lift motor potentiometer value, SPEED reads speed from speed sensor )
Delta:(TIME display shows lift motor potentiometer value, SPEED reads speed from speed sensor)
Press ELEVATION +/-to vary elevation position and to test lift relay. This can also
be used to lower lift motor if stuck in elevated position. 
CAUTION: DO NOT exceed potentiometer ranges. Remove Safety Key from position before exceeding range.
Press „START‟ to test lower board relay (a “click” sound)
Press „ENTER‟ to repeat above test or remove safety key and replace to return to the normal mode.

Lift motor calibration is needed if any of the following has taken place: The lift motor has been removed from the frame The actual and the displayed elevation angle does not match
1. Manual 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 screws 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 by removing and reattaching safety key.
E7
The values the lift motor potentiometer is sending are not within the preset limits. Check the potentiometer I/O value from the service menu and compare it to minimum and maximum reference values in Table
1. The potentiometer value is also displayed on the user interface when “error 7” appears.
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 (Figure 5) 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.
