11-6) ADJUSTING HALF-TURN FILM FOR COLOR CHANGE
The machine will stop automatically if either of the needle position lamp or the needle set lamp is off on the color
change box. In this case, adjust the half-turn film as below.
�
Adjust the position of the color cam using the SWF spanner (in basic accessory kit). Open the half-turn film cover
and align the center of the half-turn sensor with the center of the film. The roller should be at the center of the
straight line of the color change cam when the needle stops at the center of the needle hole on the plate as shown
in [Fig.11-15].
11-7) ENCODER ADJUSTMENT
Adjust the encoder as below if the needle bar stops at an incorrect position.
①
Unfasten the two screws on the upper shaft of the coupling connected to the encoder.
②
Manually fix the upper shaft angle at around 98
�
by turning the main shaft lever. Adjust the encoder as shown in
[Fig.11-16]. Tighten the coupling screws when FIX POS light turns red on the operation box.
[CAUTION]
Manual color change must be performed at the upper shaft angle of 100
�
. Manual adjustment at the upper
shaft angles other than 100
�
may cause damage on the controller and the take-up unit.
