2700SZ Sewing Machine Instructions

General Safety Instructions

1. Do not place your foot on the pedal when connecting to the power source
2. Installation and initial trial-run must be done by a skilled perfessional
3. Open control box or motor cover under electrical power is not permitted
4. Ensure the eathing system is in working order
5. When doing the following, the machine has to be disconnected from the power supply:
   a. Threading the machine, replacing needle, bottom thread
   b. Installing, dismantling or repairing
   c. When the machine is being moved, turned over, or adjusted

Environmental Requirements

1. Do not work in a damp or wet environment
2. Voltage requirements – 210V~240V
3. Must be adequately grounded for safety
4. Do not work at high temperature
5. Do not run motor and control system near ferromagnetic or high radience area.

Direct Drive Motor & Components

The servomotor is composed of control system and motor.
A. Control system includes control box and speed controller

This control system features quick start, quick stop, accurate needle positioning and speed settings. The motor also features a self-protection system against lower voltage, over current and over heating.

Specifications

Direct Drive Installation

Install control box and speed controller as figure below.
Using screws, mount the control box and speed controller onto sewing table.

Direct Drive Motor Installation:

1. Rotal Installation
   a) Remove the hand wheel, belt cover and wind blade on the sewing machine b) Install the Fan blade (figure 1) and rotor (figure 2) into the shaft of sewing machine as seen above. Secure parts into place with washer (figure 3) and screws (figure 4 & 5).

2. Motor Installation
   Using a special plastic positioning jib (figure 6), install into sewing machine over the rotor (figure 2) directed then secure with screws (figure 8). Screw down to be able to easily pull out the positioning sleeve. (Note: Use caution when installing and pay attention to the magnet suction, as this can cause injury to hand).

3. Check Rotar & Stator Installation
   a) Remove rubber hole stopper (figure 9). b) Check the plane of the rotor and ensure the stator is flat, surface should not exceed 1.5mm (See section figure A). If area is more than 1.5mm, remove the motor and the rotor with gasket to adjust (figure 11). c) Adjust to fit back rubber hole stopper. (Note: The distance between the two should be as small as possible. If more than 1.5mm, motor torque will decrease).

4. Hand Wheel Installation
   a) Turn the sewing hand wheel by hand , make the needle stop at the highest level
   b) Put the hand wheel in the rotor, and mark the calibration line of the motor housing with the scale 5 (Figure B).
   c) Tighten two screws (figure 5), and keep the clearance of hand wheel and motor 1.5mm- 2.5mm (Figure C). (Note: Overlock machines will have three little strips (Figure D).

Entering the Parameter Menu:

1. Ensure the sewing machine is on
2. Press the “P” key, then press the “+” key. The screen will display “P-00”
3. Press the “+” key again to change the “P-00” to “P-02” (P-01 and P-02 are speed and motor direction patemeter)
4. Press “P” key again to enter into parameters – screen will display “!”
5. Press “+” or “-” to scroll through the parameters list
6. Press the “S” key to save the desired parameter and exit the parameter screen

Restore Factory Settings:
To restore the factory settings, press the “P” key and the “+” key. The screen will display “P-00” , then press and hold the “S” key for 3 seconds.
