6. DIP SWITCHES ON THE CIRCUIT BOARD

[1] DIP switches on MAIN circuit board

The DIP switches on the MAIN circuit board are described in the table below.
No. Name (function) of mode
SW1 Change-over of thread trimming
speed
SW2 Change-over of loop cut rotation
operation
SW3 Manual change-over of start-up
speed
SW4 Change-over of loop cut operation
SW5 Change-over of starting switch
operation
SW6 No setting
SW7 Change-over of cut operation of
splice discharging
SW8 No setting
(Caution) Data can be taken in by re-turning ON the power.
1. Change of thread trimming speed is performed. Standard is set to high speed.
Actually, thread spreading speed is changed. Use this switch when short trimming of thread in thread spreading
occurs.
SW1 does not function normally until it is changed together with DIP SW No. 7 on the sewing machine servo
circuit board (SDC). So, be careful.
2. Perform the change-over when the belt loop width is 16 mm or more and scattering of cross cut chips is
remarkable.
Cycle time is delayed to some extent.
3. This switch is used for confirmation of design. Be sure to turn OFF when using it in sewing.
It is possible to set the starting speed of the machine head motor with MANUAL.
4. This switch changes the sequence of delivery of belt loop receiver and fork.
Normally, belt loop is delivered to fork after cutting, but when the switch is turned ON, the belt loop is cut
after the fork has come to the delivery position.
Cycle time is delayed by approximately 0.2s. Use this switch when the delivery of belt loop is terrible.
5 This switch allows the start switch to input continuously. For the standard setting, the start switch is designed
not to start even if the start switch is pressed before the belt loop comes to the intermediate waiting position.
This function is used for durability test or the like and the safety function is ignored.
Be sure to use the switch with OFF without fail.
6. No setting
7. This is a function not to discharge belt loop splice at one time but to cut it in small pieces on the way when
belt loop splice discharging is performed.
Secondary trouble of belt loop splice can be avoided by cutting in small pieces. However, cycle time is
increased. It is recommended to use the switch with OFF.
8. No setting
Standard setting
OFF When the switch is set to ON, the speed is set to low.
OFF When the switch is set to ON, loop cut goes up after rotation
when belt loop width is 16 mm or more
OFF When the switch is set to ON, setting of individual data is
effective.
OFF When the switch is set to ON, rear cut operation is set.
OFF When the switch is set to ON, continuous operation is
effective.
OFF
OFF When the switch is set to ON, cutting on the way is possible.
