the box

Chapter 1 General Information
2 Owner’s Manual of BECS- A15 Computerized Control System
Matters forAttention on Installation
Attention Don't jam the vent on the device. Don’t insert other items into the machine, or it
may get fire.
Attention Make sure the installation direction is correct.
Attention
Don't expose the machine to humidity gas, corrosive gas, water, and other
flammable material.
Matters forAttention on Cable Connection
Forbidden Don't test the insulation of the circuit loop.
Forbidden
Never try to connect the overloaded electronic device on the connectors (like
sockets or terminals).
Attention The insulation
condition of each cable (no matter signal cable or power cable)
should be ensured.
Attention The signal cables and power cables should be separated. Never tie them together.
Attention All the cables should be well fixed. Don’t put any strength on cables. Make sure
each turning point of cable is well protected. Add shelter pipes to increase
insulating capability if necessary.
Attention
must be grounded. The equipment-grounding conductor should
use the wire
with insulation having an outer surface that is green, with or without yellow
stripes. the cross-sectional area of the wire shall not be less than 2mm2, and the
grounding resistance should be less than 10Ω. The equipment-grounding
conductor must be pressed crimping to the circular pre-
insulated terminal and
connected to the position where the grounding mark of the machine case is.
Matters forAttention on Operation
Danger Don't operate the machine when there is any damage on the shelter of the running
parts.
Forbidden When machine is running, do not touch any running part.
Attention Make sure the configuration of power supply is in normal. Use stabilized voltage
power supply when the change of voltage is beyond the range of -10%~10%.
Attention In case of warning, please check out the problem. Operation can only be carried
out again when problem is solved.

Chapter 1 General Information
Owner’s Manual of BECS- A15 Computerized Control System 3
Attention The power supply switch has over-current protection function. If the over-current
switch is activated, the switch can only be closed after 3 minutes.
Matters forAttention on Maintenance and Inspection
Warning If you need to open the machine cover, please cut off the power supply at first.
Due to the capacitance, operator must wait at least one minute before opening the
machine cover.
Attention Circuit boards can be damaged by static. The
circuit boards can only be
disassembled by professional technicians.
Attention
If machine is inactive for a while temporarily, users must power on the machine
regularly (once by every 2 or 3 days, more than an hour for each time).
Attention
If machine is inactive for a long time, users should have the machine checked
before power-on.
Matters forAttention on Rejection
Attention Rejection should obey the rules and regulations set by national industrial
electronic standards.
1.2 Main Features
1. User-friendly Interface on Touching Panel
The adoption of the touching panel technology offers user the delightful operation and
easy learning. The beautiful screen display turns everyday work into joyful experiences.
2. Huge Memory Capacity
The memory capacity reaches 100 million stitches, which can meet demands of different
customers.
3. Maximum StitchAmount of One Pattern Reaches Two Million
At present a single pattern in the system has the maximum of 2 million stitches and 1,000
times of automatic color changing.
4. Multi-Task Parallel Operation and Free Shift among Tasks
During the embroidery, actions like pattern input & output, preparation for the following
patterns and modification of parameters can be carried out.
5. Storage of Frequently Used Parameters and Color-Changing Order for Each Pattern

Chapter 1 General Information
4 Owner’s Manual of BECS- A15 Computerized Control System
Pattern will be saved along with its parameters, color-changing orders and needle bar
colors. System can save the operational details for each pattern. Users can set parameters for a
pattern during the embroidery process of the previous pattern, which will save time and
improve efficiency. Moreover, it is one basis to realize network management.
6. Pattern Input/Output via USB
Customers can use USB disk for data transfer. USB disk supports DIR operation, which is
easy for pattern management. For each directory, system supports operation of 400 patterns or
sub-directory. There is no limitation of directory levels. Patterns in the formats of Binary,
Ternary and Z-nary can be loaded.
7. Patch Embroidery
This function can set a patch point at the position of color code or stop code, and when the
machine embroiders to the patch point, it will halt and move out frame for patching. After
sticking a patch, user would press the start key to return the frame and continue embroidering.
8. Brake Adjustment
User can adjust the parameter of brake to let the main shaft stop at the correct position
according to the characters of his own machines.
9. Save Start Point
This function can save the start point of each pattern, which saves the work of user to
search the start point manually at embroidering the identical pattern.
10. Mechanical Maintainence and Debugging
This function is to easily judge the malfunctions at maintaining and debugging the
machine, such as encoder testing, main shaft speed testing, machine parts testing and the main
shaft stopping at any position, etc.
11. Multi-Language Support
Currently, the system supports the display in Chinese, English, Spanish and Turkish,
Russian, French and many other languages.
12. Pattern Output
Patterns can be output and saved into USB disk. Adoption of TAJIMA’s binary format

Chapter 1 General Information
Owner’s Manual of BECS- A15 Computerized Control System 5
enjoys the advantage of data transmitting through the World Wide Web (other formats may not
be transmitted directly).
13. Repetition Embroidery
The user can increase embroidery productivity by using the function of repetition
embroidery, which can also be used with cyclic embroidery.
14. Cyclic Embroidery
With this function, the machine can automatically return to the origin and start the same
embroidery again when finishing the pattern one time. User also can increase productivity
rapidly by combining this function with special pattern-making function or repetition
embroidery function.
15. Pattern Compiling
(1) Compiling the Data of Selected Pattern to Generate New Pattern
Users can compile any pattern according to zoom ratio, rotate angle, normal repetition or
partial repetition to generate a new pattern and save it to memory. The newly generated pattern
can be used for embroidering, output or other operations.
(2) Compiling the Combined Pattern
After setting the combined pattern, the system can compile that pattern to generate a new
one and save it to memory. The newly generated pattern can be used for embroidering, output
or other operations.
16. Letter Pattern
There are 28 built-in font libraries. Users can make letter groups and change letter orders
according to different tasks. This operation is vivid, simple and easy managing.
17. Pattern Edit (under developing)
18. Speed Adjustment
The highest speed for embroidery can be preset. During embroidery, speed may change
automatically along with the change of needle interval.

Chapter 1 General Information
6 Owner’s Manual of BECS- A15 Computerized Control System
19. Thread-trimming
Thread-trimming can be manually operated. The machine can trim the thread
automatically at the end of embroidery process or at color-changing.
20. Thread-breakage Detection
In case of thread breakage or running-out of bobbin thread, the machine will stop and give
warning by indicator.
21. Color-changing
At the color-changing point, user can either perform the color-changing manually or let
the system do it automatically according to the preset order.
1.3 Technical Specifications
1. Maximum number of patterns saved in memory: 800
2. Memory capacity: 100 million stitches
3. Screen resolution ratio: 1280*800
4. Network port speed: 100Mbps
5. Supported method for data exchange: USB disk, network (temporarily unavailable)
6. Control precision: Minimum controllable stitch interval is 0.1mm
7. Stitch range: 0.1mm~12.7mm
