Set new value (level) with potentiometer on the machine.
Press the F2 key.
Press the E key. New value 17 (lower break point)
is entered.
Press the P key once. Display of the actual parameter
number.
or
Press the P key twice. Exit programming.
These values are saved when you start sewing. They remain in effect even after turning the machine off!
Note
If you set a value on the potentiometer, which is between the actual break points, both values will be overwritten when
the E key is pressed. Only after that is it possible to program new lower and/or upper break point values.
9.16.4 Potentiometer Adjustment on JUKI Machine Model LU-2210/LU2260
1. Set potentiometer (A) in the machine head, which is accessible by a bore at the rear, to the left endstop.
2. Turn the handwheel to position 1 for the speed depending on high lift (minimum high lift).
3. Set parameter 126 to 3 (activation of external potentiometer for
the speed depending on high lift).
4. Select parameter 188. The V820 control panel display
shows e. g. 3000 05 08 18
5. Press the F1 key, and the display shows e. g. Poti 185
6. The display value should be between 170 and 200.
7. Is this the case, the adjustment is completed.
Proceed with point 10.
8. Should the value be outside the limits, there would be an
acoustic signal.
9. Loosen the 4 screws on the machine head and remove
the cover with the setting knob. Loosen adjusting screw
(B) and turn the potentiometer shaft to set the value
between the above limits. Then the acoustic signal will
be switched off.
10. Press the F1 key. The displayed value is taken over, and a short acoustic signal will be issued.
11. If the display shows EEEE, turn the potentiometer (A) in the machine head, which is accessible by a bore at the
rear, to the right so that EEEE goes off, and level 1 (maximum speed) is displayed.
