FOR TYPO YS-626A .C . SPINDLE
DRIVE
Instructions for Removal and
Installation of the Spindle
Drive Circuit
Boards
1 . Shut off the
Control and turn off
the
Main
Power Switch
2 . Open the
door to the Spindle Drive Cabinet
3 . Remove the
clear plastic cover on
the
Spindle
Drive .
4 . Make a list of
all the wires onto the terminal
strips on both the large and small
boards on the spindle
drive . These strips are
located on the left side of both
boards and also
there are some small
terminals on the bottom of the small board .
5 . Remove all wires
from the board
to be replaced
*CAUTION : Insure that
yourwire list
is complete andcorrect before removing any
wi
res
6 . Remove all
ribbon connectors and
if necessary remove the connector with the yellow
wires at the
top of the large board (it has
5 straight pins in a row)
7 . If the large board
is to be removed : At the top
of the board there are 2 pairs of
Red and
Whitewires (the wires
are woundtogether as a twisted pair) Trace
these
back
to theirwhite connectors and
pull the connectors apart .
*NOTE :
These plugs are labeled
I
and
2 .
3 . The small
board is held down by plastic
squeeze tabs . To remove the board, squezze
the tabs together
with a pairof needle-nose pliers
whilegently lifting the
board . When the board
is free, lift it gentlyaway
,and set it aside .
*CAUTION : When handling
circuit boards ensure that they are
not
set on a
wet
surface
. If possible set them
on plastic of some sort .
9 . The large board
is no nnally held down by 9
screws,8 of which are located on the
outside
edgeof the board . The remaining
screw is located in the very middleof
the board .
Remove the screws and gently
lift the board free .
10 . To install
the new boards simply
reverse the aboveprocedure . All of the Ribbon
cables and all of
the connectors are keyed
to
fit only
in one direction in their
appropriate sockets
. Ensure that all of the wires on
the terminal strip
are
in
their proper location and
that they aretightly
screwed down .
If you have
any questions or problems please
call
