#3
After a few
seconds
after the
R/W switch
is pressed,
an error
code
appears.
#4
The work
clamp does
not move
up and
down
when the
foot switch
is stepped
on.
Probable causes
1. With error code [E.40], a floppy
disk is not inserted.
2. With error code [E.41] or [E.4F],
the floppy disk is defective.
3. Panel circuit board defective
1. Foot switch and code defective
2. Any cord in the control box is
defective.
3. Fuse blown
Check/repair/adjust
• When a floppy disk is inserted into the FDD, check
the sound of the motor.
• When error code [E.40], [E.41], or [E.4F] appears,
insert other floppy disk into the FDD.
If the FDD reads the floppy disk, the original disk
is defective.
(Make sure that the power is turned off.)
• Remove the connector for foot switch connected
to the outside of the control box, and check the
continuity between pins 1 and 2, and pins 7 and 8
in the connector on the cord. (For pneumatic
specification, check the continuity between pins 3
and 4.)
The continuity in each case should be normally
or 0 when the switch is stepped on.
• Insert the connector checked above, open the
control box, and check the continuity between
pins 1 and 2, pins 3 and 4, pins 5 and 6 in
connector P19 (FOOT) on the PCB.
(Without removing the connector, put a tester
from the lead side.)
The continuity in each case should be normally
or 0 when the switch is stepped on.
• Remove fuse no.1 and check the continuity.
(If there is no continuity, go to the next item.)
