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

Connection of Power Voltage and Control Box Cable

2) Cable Connection to Control Box

A. Internal Wiring of Control Box (Common in all types)

See“Block Wiring Diagram”

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.

Power On

Indicate initial setting status

on the operation panel.

Sewing

Set the desiring pattern

(example: pattern no. 3)

Indication lamp is on.

[Note]

When the power turned on, if buzzer tone rings and U P is displayed on indication device, it means needle bar is not

on the up stop location. Therefore, turn the pulley to the front by hand that the needle bar can be at up stop location. Then,

indication device discappers U P and shows zigzag-width and you can start sewing.

·ZigZag-width on indication device blinks and at the time,

pressing left scallop key, pattern number and shape

number are displayed on the indication device.

3. Change the shape number by using + and –key.

(Ex: selection of pattern shape no. 3)

4. Press PARA/SET key when the change is completed.

·ZigZag-width is displayed on the indication device.
