Repairing the knitting machine
Needle selection displacement
14. Stop the carriage in the reversing position and enter the test result with the
help of the switch (3).
15. Resume the test series. Press the (5) key for this.

The next line of the test series is selected automatically. Internally, the
reaction time is increased by "1".
16. Resume the test series until one error occurs in both carriage directions
(steps 9 to 15).

Now you have reached the limit for the "positive" reaction time.
17. The second part of the test follows. Press the (5) key for this.
The test will be carried out automatically with "negative" reaction times.
18. Repeat the steps 9 to 15 until one incorrect selection occurs in both
carriage directions.

The switches automatically get inactive (grey).
19. The test series for this impulse sensor is finished.
20. Calculating the reaction time.
Tap the (6) key for this. The optimum reaction time is calculated. This
takes about 10 seconds. When the calculation is finished a message
appears on the touch screen.
21. Repeat the test series for the rear impulse sensor.
For this fix the knitting row 40 - enter "SPF40".
Attention: With step 8 tap on the "Reset" (7) key. (If you tap on the (1) key,
the recently determined values are deleted.)
Repeat the steps 8 to 20.
22. With a tandem machine: switch the option in the "Right/left carriage" to the
other carriage. Repeat the steps 8 to 21.

The determination of the needle selection displacement is finished.
If you are not sure that no error occurred, repeat the check for
both carriage directions.
If you accidentally tap the (5) key twice, one line of the test
series is skipped. The test series is not valid. You have to
execute again the entire test series (step 8).
