Cau tion

If the material edge sensor is used in combination with the operation panel, carefully read the Instruction Manual for the material edge sensor beforehand.

4-8. Automatic thread trimming switch

• This switch is used to automatically actuate the thread trimmer in a process where the sewing machine automatically stops or when the material edge sensor is used. (if the automatic reverse stitching (for end) is specified, the thread trimmer will actuate after the sewing machine completes the automatic reverse stitching (for end).)

4-9. One-shot automatic stitching switch

• This switch is used, in the constant-dimension stitching mode, rectangular stitching mode, or in the process where the material edge sensor is specified, to make the sewing machine automatically perform sewing at the specified speed until the end of the process is reached only by driving the sewing machine once.

4-10. Thread trimming prohibition switch

• This switch is used to temporarily make the thread trimming function inoperative. The other performance of sewing machine is not affected by this switch. (If the automatic reverse stitching (for end) is specified, the sewing machine will perform the automatic reverse stitching at the end of sewing.)

• If the automatic thread trimming switch and the thread trimming prohibition switch are both specified,

the machine will not perform thread trimming but stop with its needle up.

4-11. Key lock

• In order to prevent the specified data on the number of stitches or the processes (A, B, C and D, or step information) from changing by mistake, the setting switch can be locked. (Even with the setting key locked, the pattern to be sewn and the value on the bobbin thread counter can be changed.)

• For the setting procedure, refer to 4-13 Setting for functions and set function No. 17, Key lock function (key lock is effective with setting of “1”).

5-3. How to use the bobbin thread counter

The machine detects the number of stitches. The preset value on the bobbin thread counter is subtracted in accordance with the number of stitches detected. (Every time the detector detects 10 stitches, 1 is subtracted from the preset value on the bobbin thread counter.) When the value on the counter becomes a minus value as

........

(

→ 1 → 0 → –1), the buzzer (peeps three times) and the pop-up display inform that the time to change the bobbin thread has come. When IP-100 is mounted on LH-4168 and LH-4188, the bobbin thread counters are separately installed for lefthand bobbin and right-hand bobbin . However, the display on the panel is either one of them, and the display can be changed with switch 1.

Cau tion

2) Set an initial value using counter value setting switches 笳 and 笘.

The bobbin thread counter cannot be reset during sewing. In this case, make the thread trimmer actuate once.

*Actually, the bobbin thread counter is affected by the material thickness and the sewing speed. So, adjust the

initial value of the bobbin thread counter in accordance with the operating conditions.

3) Once the initial value is specified, start the sewing machine.

4) When a minus value is shown on the counter, the buzzer peeps three times and the pop-up display appears, replace the bobbin thread.

Bobbin thread replacement warning pop-up

5) After the bobbin thread has been properly replaced, press counter reset switch 笆 to return the value on the bobbin thread counter to the initial value. Now, re-start the sewing machine.

6) If the remaining amount of bobbin thread is excessive or the bobbin thread runs out before the bobbin thread counter indicates a minus value, adjust the initial value appropriately using counter value setting switches 笳 and 笘.

If the remaining amount of bobbin thread is excessive ..... Increase the initial value using the “+” switch.

If the remaining amount of bobbin thread is insufficient .... Decrease the initial value using “–” switch.

5-4. No. of pcs. counter

The No. of pcs. counter counts up the number of finished products every time the machine performs thread trimming. (0 → 1 → 2

...........

→ 9999)

5-5. Re-sewing switch

The re-sewing switch is used when the bobbin thread runs out during the corner pattern sewing step or the step

pattern sewing step. Explanation of the re-sewing switch is given using the corner pattern as an example.

d

1

a

C b

1) When the bobbin thread has run out during the sewing

of a corner a, take the position at which you have noticed run out of the bobbin thread as b. Bring the

pedal to its neutral position to allow the sewing

machine to stop.

2) Depress the back part of the pedal to perform thread

trimming.

3) Press re-sewing switch 1. c

4) Replace the bobbin with a new bobbin and sew over the

finished seam. d

5) Depress the front part of the pedal and continue to depress the pedal until the stop position of the current step.

6) When re-sewing switch 1 is turned ON again at the stop position, the step is changed over to the subsequent step, and the corner pattern can be continued.

* When thread breakage or the like occurs during the free

stitching operation d using re-sewing switch 1, set the pedal to neutral and perform thread trimming operation by depressing the back part of the pedal. Perform threading and slightly return the material edge. Then press re-sewing switch 1 and the free stitching can be continued. After this, the operation is the same as steps 5) and 6).

ENGLISH

Cau tion

When returning to the first step without using re-sewing switch 1, the step

display returns to “1” and the sewing can

be performed from the first by

depressing the back part of the pedal to

perform thread trimming.

– 53 –

5-6. Needle up/down compensation switch

Every time needle up/down compensation switch 笊 is pressed, the needle goes up when it is in its lowest position or comes down when it is in its highest position. This compensates the stitch by a half of the predetermined stitch length.

1

Note, however, that the machine does not run continuously at a low speed even if you keep the switch held pressed. Also, note that the needle up/down compensation switch is inoperative after turning the handwheel by hand. Thread trimming is operative only at the time of stitch compensation after depressing the front part of the pedal once.

5-7. ON/OFF switch of the material edge sensor

• When the material edge sensor, which is optionally available, is connected to the operation panel, the ON/ OFF switch of the material edge sensor becomes effective.

• If the material edge sensor is specified, the sewing machine will automatically stop running or perform thread trimming when the sensor detects the material edge.

Cau tion

If the material edge sensor is used in combination with the operation panel, carefully read

the Instruction Manual for the material edge sensor beforehand.

5-8. Automatic thread trimming switch

• This switch is used to automatically actuate the thread trimmer in a process where the sewing machine automatically stops or when the material edge sensor is used. (if the automatic reverse stitching (for end) is specified, the thread trimmer will actuate after the sewing machine completes the automatic reverse stitching (for end).)

5-9. One-shot automatic stitching switch

•This switch is used, in the step pattern , or in the process where the material edge sensor is specified, to make the sewing machine automatically perform sewing at the specified speed until the end of the process is reached only by driving the sewing machine once.

5-10. Thread trimming prohibition switch

• This switch is used to temporarily make the thread trimming function inoperative. The other performance of sewing machine is not affected by this switch. (If the automatic reverse stitching (for end) is specified, the sewing machine will perform the automatic reverse stitching at the end of sewing.)

• If the automatic thread trimming switch and the thread trimming prohibition switch are both specified,

the machine will not perform thread trimming but stop with its needle up.

5-11. Key lock

• In order to prevent the specified data on the number of stitches or the processes (A, B, C and D, or step information) from changing by mistake, the setting switch can be locked. (Even with the setting key locked, the pattern to be sewn and the value on the bobbin thread counter can be changed.)

• For the setting procedure, refer to 5-13 Setting for functions and set function No. 17, Key lock function (key lock is effective with setting of “1”).
