Preface
CAUTION:
Please read this manual carefully, also with
related manual for the machinery before use the
controller. For installing and operating the
controller properly and safely, qualified
personnel are required.
This product is designed for specified sewing machines and must

Safety Instruction
（1） All the instruction marked with sign must be absolutely
observed or executed; otherwise, personal injuries or risk to the
machine might occur.
（2） This product should be installed and operated by persons
with appropriate training only.
（ 3 ） Before connecting power supply cords to power sources, it’s
necessary to make sure that the power voltage is in the range indicated
on the product name plate.
（4） Make sure to move your feet away from the pedals while
power on.
（5） Turn off the power and remove plug prior to the following
operations:
■ Connecting or disconnecting any connectors on the control box；
■ Repairing or doing any mechanical adjustment；
■ Threading needle or raising the machine arm；
■ Machine is out of work.
（6） Make sure to fasten all the fasteners firmly in the control
boxes prior to the operation of the system.
（ 7 ） Allow an interval of at least 30 seconds before repapering the system
after power off.

（8） Repairs and maintenance work may be carried out by special
trained electronic technicians.
（9） All the replacement parts for repairing must be provided or
approved by the manufacturer.
（10） The controller must be firmly connected to a properly
grounded outlet.
（11） Ground wire installation (special attention).
CAUTION：
Be sure to connect the controller to a properly grounded
outlet. If the grounding connection is not secured, you
may run a high risk of receiving a serious electric shock,
and the controller may operate abnormally.
1. Basic parameters
2. Secure wiring and grounding
The system is powered and ready for use, you must ensure that the AC input is
securely grounded (Figure 2-1). System grounding wire is yellow and green lines, make
sure the ground wire securely connected to the machine head (such as connecting to the
head of the screw), in order to ensure the safe use, and prevent abnormal situation
