10-8) Encoder Adjustment; 10-19) Jump Solenoid Adjustment - SunStar SWF/B Series User Manual

10-8) ENCODER ADJUSTMENT

Adjust the encoder as below if the needle bar stops at an
incorrect position.
① Unfasten the two screws on the lower shaft of the
coupling connected to the encoder.
② Manually fix the main shaft angle at around 98° by turning
the main shaft lever. Adjust the encoder as shown in
[Fig.10-14]. Tighten the coupling screws when
light turns on the operation box.
10-9) JUMP SOLENOID ADJUSTMENT
Adjust the position of the jump solenoid when you replace it or if you find errors in the solenoid.
1) Adjusting the standby position (assembling the solenoid
and the bracket)
① Unscrew the solenoid with a jump solenoid adjusting
spanner (SWF basic kit). Fasten the nut at a point
where the distance between the operating limit of the
solenoid is 3.5mm from the bracket as shown in
[Fig.10-15].
② If the distance is longer than 3.5mm, the solenoid will
interfere the operation of the needle bar controller,
causing the controller to fail in returning and stopping
the needle bar. If the distance is too short, the needle
bar controller will hold the needle bar and not allow
jumps.
2) Adjusting the position of the solenoid (assembling the
solenoid-installed bracket to the arm)
① Adjust so that the bracket is 1mm from the side of the
arm as shown in [Fig.10-16]. Fasten the bracket.
② Incorrect position of the solenoid may cause the needle
bar controller to interfere with the operation of the
needle bar.
