5. Installation of synchronizer (optional part) for external mounting motor Installation of inside synchronizer:

a. Dismount the belt pulley of sewing machine, and install the needle positioner on the sewing machine head with its indicator lamp upward (as shown in Fig. 5-1);

b. Install the red and green sychronizer magnets in corresponding position of belt pulley of sewing machine (as shown in Fig. 5-2); Fig. 5-2 shows two installation methods of different belt pulleys, respectively.

c. Mount the belt pulley of sewing machine back to the sewing machine, adjust the axial position of the belt pulley to guarantee about 0.5~1mm spacing between the needle positioner magnet and needle positioner, and then tighten the fastening screw on belt pulley.

d. Insert the sychronizer plug into corresponding socket of motor control box. e. Adjust the needle position Adjustment of upper needle position: Power on the system. Start the motor and stop the sewing

machine in the upper needle position, and then observe whether the sewing machine stops in the required needle position; if the sewing machine does not reach the upper needle position, adjust the green sychronizer magnet clockwise within its mounting groove; if the sewing machine exceeds the upper needle position, adjust the green sychronizer magnet counterclockwise within its mounting

groove. Then start the motor and check whether it is in the upper needle position; if not, repeat the above adjustment until it is correctly in the upper needle position.

Adjustment of down needle position: The adjustment method of down needle position is same with that of upper needle position, and the only difference is it is adjusted with a red needle sychronizer magnet.

Installation of outside synchronizer: a Installation of synchronizer: Set the sychronizer onto the sewing machine head belt pulley

spindle or butting connector (adapter), and tighten the fixing screw on the aluminum shaft of sychronizer. Fix the relative position of synchronizer and machine head with a fixed baffle (as shown in Fig. 6).

bAdjustment of synchronizer: Before adjustment, make sure that the power switch is turned off, loosen the fixing screw of upper cover of synchronizer, and take down the upper cover of synchronizer.

Adjustment of upper needle position: Rotate the hand wheel of sewing machine head manually and stop the sewing machine in the upper needle position, press the hand wheel, rotate the sensor of upper needle position of positioner to aim the notch center of such sensor at the center of corresponding photoelectric sensor on the circuit board. Then the adjustment of upper needle position is finished.

Adjustment of down needle position: Rotate the hand wheel of sewing machine head manually and stop the sewing machine in the lower needle position, press the hand wheel, rotate the sensor of lower needle position of positioner to aim the notch center of such sensor at the center of corresponding photoelectric sensor on the circuit board. Then the adjustment of lower needle position is finished.

6. Then fix all the cables below the sewing machine table with the attached thread-pressing

fastener and nylon cable ties.

Operating instruction of pedal: Step on the pedal slowly from the initial position 0,

and when it is in position 1, the sewing machine starts to sew at a low speed; when it is in position 2, the sewing machine sews at a high speed. In the position between 1 and 2 is step-less speed regulation.

When the pedal is stepped on backward from the initial

position 0 to position -1, the system shall conduct conversion of needle positions; if it is originally set that the sewing machine stops in lower needle position, step on the pedal, and it will stop in upper needle position; if it is originally set that the sewing machine stops in upper needle position, step on the pedal, and it will stop in lower needle position.

Operating instruction of operation panel: z Selection key of needle position above or below/positive and negative rotation switch key

Needle position setting: Short-press the key, and the sewing machine needle position can be changed; in setting, LED will display F1, F2 or F3, with 3s display time. In F1 status, when the pedal stops in the initial position, the sewing machine stops in lower needle position; then step on the pedal backward, and the needle position will turn to the upper needle position. In F2 status, when the pedal stops in the initial position, the sewing machine stops in upper needle positio; then step on the pedal backward, and the needle position will turn to the lower needle position. In F3 status, when the pedal stops in the initial position, the sewing machine stops in upper needle position; then step on the pedal backward, the upper needle position remains the same.

Note: This function is invalid when the synchronizer is not mounted or the synchronizer plug is not inserted into the motor control box.

Operation panel diagram: Setting of motor rotation

direction: Long-press this key (at least for 3s), and the rotation direction of motor can be changed. When the setting changes, LED will display d1 or d2; d1 means the motor rotates counterclockwise, d2 means the motor rotates clockwise, and the display time is 3s. z Speed mode switch key

Short-press this key once, and the speed mode of the motor may be changed, and two speed modes (P1 and P2)are adopted for this machine; P1 mode means low-speed range mode and in this mode, in the process of stepping on the pedal, there is one section of low-speed range, within which, the motor shall keep running at the lowest speed, and it will be

accelerated when reaching the end position of low-speed range. P2 mode means non-low-speed range mode and in this mode, in the process of stepping on the pedal, the machine will be accelerated immediately after starting. In the setting, LED will display P1 or P2, and the display time is 3s.

Long-press this key once (at least for 3s), and the soft start mode of motor can be opened or closed; in the setting, LED will display S0 or S1; when the machine is set in S1, the soft start mode is opened, and when the system is electrified for the first time or the pedal is stepped on reversely and the needle position is switched, when starting the motor, the motor will run at a speed of 200rpm for the first two circles, and then the motor will run at the normal operating speed. When the machine is set in S0, the soft start mode is closed. z Speed setting key

The key is used to display and set the maximum working speed of motor. When the motor is in standby mode, press this key, and it will display the current speed of motor, and then press this key again, and the speed will increase by 100rpm; the speed of motor can be adjusted between the minimum speed and maximum speed and when it reaches the maximum value, press this key, and the speed will return to the minimum value; hold down this key, and fast circular adding setting can be made, LED will display the thousand and hundred of motor speed; for example, for 3,800rpm, LED will display: 3 8, and the display time is 3s. (The maximum speed limit of motor is set in the factory according to users requirement)

Fault Code and Repair

If a fault occurs to motor system, the system LED panel will display corresponding fault code; when several abnormal faults occur at the same time, the display window will display all fault codes by turns, the retention time of each fault code is about 4s, and users can repair them according to the fault codes. If the fault cannot be removed, please contact the dealer or the manufacturer.
