1) Power Voltage and Power Code Connection

(1) Voltage Specification

Match the indication of voltage to specification of power code and connect the cable.

1. Must not use on condition that voltage specification is different.

2. In case of change the using voltage, refer to the article. [Power Voltage Changing Method] Single-phase connection( 100V, 110V, 120V, 200V, 220V, 240V)

Three-phase connection (200V, 220V, 240V, 380V, 440V)

(2) Power Voltage Changing Method

In Voltage of 110V series, 220V series and 380~440V specification, you can change into the voltage as follows by just

changing the location of power voltage switching connector

■ Voltage change of 100~220V specification Trans former Model: KM-2070P-110

■ Voltage change of 220V specification Trans former Model: KM-2070P-220

Upper Figure is wiring diagram based on KM-2070P-7 model and the wiring in case that selected Knee-lifter switch (including presser foot solenoid) for option As KM-2070P model are none-thread trimming type, it does not need to connect cable for thread trimming , wiper, tension release solenoid. Switch cable consists of two; white and blue connector(Knee-lifter switch is option) White connector : Connect reverse button Blue connector : Connect Knee-lifter switch (connect presser foot solenoid cable as well) In case of power cable connection, pay attention to fix to table that interference does not occur with belt.

■ Considerations to set location of base line In the sewing pattern as figure [a], moving the location of base line 2mm (L-20) to the left, it is sewn as shown in the figure [b]. When moving location of base line 3mm (L-30) to the left and setting zigzag width of 4mm, due to exceeds the sewing range as shown in the figure [c], so zigzag width is automatically set to the maximum range not exceeding the range and sewing is done such.

Yet, setting width of 2mm in this condition, sewing is done s figure [d]

<Note>

Unless set the left/right stop location of needle, it can stop anywhere. In case of straight-line pattern and blind pattern, left/right stop location of needle is not reflected. Setting left or right stop, though step the pedal to neutral or pedal while sewing, the sewing will continue to the designated

location.

In case of left stop, the machine moves to the maximum left stitch and in case of right stop, it moves to the right stitch. In scallop, in case of right stop, the machine moves to the next right stitch and in case of left stop, it moves to the next left

stitch.

<Note> When moving the needle to the needle up stop location, do not move by turning the half-stitch key or sewing machine pulley by hands. Then, sewing start from left/right stop location of needle becomes invalid

< Sewing start location >

In case of right stop setting, start from the right and in case of left stop setting and start sewing from the left. In case of needle down stop, exchange the sewing material by making the needle to move to needle up stop by pedaling backward and start sewing. Then, it start at the very location. In scallop, start sewing from the right in case of left scallop and in case of right scallop, it start from the left (the top of the shape). In case of no setting of left/right stop location of needle, sewing starts from the left in case of 2 point, 3 point and 4 point pattern.

12) Up/Down Stop of Needle

13) Basic Concept for Operation of Operation Panel

- This setting is used to check location of sewing material correctly or it is usefully used for reverse function(mirror) and name stitch sewing.

Setting method is to turn on the indication lamp of down stop by pressing up/down stop key of needle. It is selected to initial value of down stop. In case of up stop, you can just press down stop key once again.

Use PARA/SET key in order to change the selected parameters (width, base location, left/right stop location, etc.). ( See the operation order in case of [parameter change])

In order to use the set value in advance, turn on the indication lamp by selecting the desired key and start sewing. (Operation order in case of [ no parameter change])

■ Condense (BackTack) Function

- Used to prevent the fabric loosening at start and end of sewing work. During sewing, if you press reverse feed button, then performs to condense sewing by the setting value(adjustment of stitch width by condense adjustment dial and feed adjustment dial), while you pressed the reverse feed button. (in case of [Fig. b]) Condense sewing is start and end condense sewing.([Fig. a])

■ Reverse Button Function

- To sew Mirror Reverse Shape is available during sewing. While pattern shape is set up to ‘5-*A’or ‘6-*A’, place the pedal to the neutral position during sewing, press reverse button , and

‘AAAA’is displayed on the indication device and reverse sewing is available. (Whenever reverse function is used, reverse button

must be used.) If you press reverse button at a mistake during sewing stop, press reverse button once more, and mirror reverse function disappears completely. While pattern shape is set up to ‘5-*A’or ‘6-*A’, during sewing, if you press reverse feed button, then performs to condense sewing by the setting value(adjustment of stitch width by condense adjustment dial and feed adjustment dial), while you pressed the reverse feed button.

<Note> Feed adjustment dial > Condense adjustment dial

When deciding width, if needle plate is for 8mm, width scope can set up to -4mm~4mm. When setting the width scope to 5mm~5mm, it digresses work scope and the needle can be broken. In this case, use by setting the maximum width to

10mm. See “zigzag width”in article 3-6).

※ Description of Shade part

■B-04 (DIST1) : It is the value indication location that rapid speed reduction is completed at stop and though stable rapid speed

reduction is available as much as the value is bigger, but final stop section gets long.

■B-08 (KC2) : It can acquire by inertia tuning and if the value gets bigger, pursuit for speed gets slow. (Common user or/and technician’s use is prohibited.)

■B-12 (KF2) : It can acquire by inertia tuning and if the value gets bigger, pursuit for speed gets slow. (Common user or/and technician’s use is prohibited.)

■B-15 (accelA) : It can acquire by inertia tuning and as the reduced speed until completion of rapid speed reduction after input pedal stop signal, if the value is bigger, rapid speed reduction is made but if it gets too big, it may not be done.

■B-16 (accelB) : In case of speed increase by pedaling, it is the value indication how fast speed increase and as this value is bigger, speed increase get faster to the objective speed but speed change can be large at the moment of reaching to objective speed.

■B-17 (accelC) : As the value indication how fast speed increases in case of speed decrease by pedaling, as this value is bigger, speed decrease gets faster to the objective speed, but speed change can be large at the moment of reaching to objective speed.

※ Example that can use above function of shade part

① Rapid stop is not done and one stitch goes further

- In this case occurs when sewing machine is operated at high speed, or in case that rapid speed reduction is not possible within short time as load of sewing machine is big. Make value B-15 and B-17 large.

② When increase or decrease sewing machine speed, in slow case of the time that motor follows the speed

- This case can occur when increase or decrease rate is small comparing to increase/decrease load of sewing machine. Make value B-16 and B-17 large.
