Optional - JUKI MOL-254N Instruction Manual

Phenomenon
6. Splice section is not dis-
charged and sewn as a
loop.
7. Clamp feed section cannot
clamp belt.
8. Clamp feed section can-
not pull out the specified
amount of the loop.
9. Bartacking position does
not correspond with the
loop position.
10. Bartacking position does
not correspond with the
loop position.
11. Length of the loop fed is
short. (MOL-254)
12. Length of the belt-loop fed
is long. (MOL-254N)
XI. OPTIONAL
Name
1. Belt loop detector (40285831)
2. Air gun (40285832)
3. Needle cooler (40285833)
4. Needle thread breakage detection de-
vice (40285834)
Cause
1. (BD) or (BE) value in the setting
screen is not proper.
2. Splice detection data set value is
not proper.
1. Loop feeding data (BC) is not
proper.
2. Loop is caught.
1. Loop feeding data (BC) is not
proper.
2. Loop is caught.
Position of loop gathering claw is
not proper as in such a case that
the loop gathering claw does not
gather the loop.
Loop width set value (1F) is not
proper.
Position is shifted due to the char-
acteristics of the material.
The feed mechanism does not
match the model setting.
The feed mechanism does not
match the model setting.
The belt loop detector generates an alarm if loops are entan-
gled and cannot be supplied as specified.
Air spray
It decreases the rise of needle heat, and decreases occur-
rence of needle thread breakage due to needle heat.
It detects when needle thread is broken, and stops to make
the alarm display.

Corrective measure
Adjust and change the value of
top end portion of splice (BD).
Adjust and change the value of
rear end portion of splice (BE).
Re-input the splice detection
data. (Refer to "VII-4. Adjusting
the belt loop splice detector"
P.40.)
Adjust and change (BC) value in
the adjustment screen.
Check whether the loop is caught
and remove the place of trouble.
