Maintenance; Replacing The Fuse; 200V Voltage Specification Changeover - JUKI LK-1900AN Engineer's Manual

9. Maintenance

(1) Replacing the fuse

(2) 100V ←→ 200V voltage specification changeover
3-phase 200/220/240V type and single-phase 100/110/120V type can be changed over by changing the
power source cable and changing over of the jumper.
Changeover of jumper
200V setting
100V setting
The machine uses the following three fuses:
1 For pulse motor power supply protection
5A (time-lag fuse)
1
2 For solenoid and pulse motor power supply
protection
2
3.15A (time-lag fuse)
3 For control power supply protection
3
2A (fast-blow type fuse)
Change over the jumper in accordance with the volt-
age used.
For the change of the connection of power source
cable, refer to the item (Instruction manual 4.-(2)) of
"Connecting the power source cord."
(Caution) When a wrong connection such as
Jumper
– 82 –
putting 200V type voltage at the time
of setting 100V type or the like is
performed, the printed circuit board
is broken. Perform the change of con-
nection after checking the voltage
used.
