o 2. I/O Board Replacement
a) Assure that all power has been removed and 30 seconds has elapsed.
b) Remove the drive front cover. See ESD precaution on page 1 and
apply grounding wrist strap.
c) Label and remove any cables from the I/O Board. The board can now
be removed by taking the four corner screws out and carefully
separating the connectors.
d) Remove the Display & Keypad Module (from the I/O Board) by
taking the four screws (that secure the assembly) out from the back of
I/O Board and carefully separate the connectors.
e) Using Figure 1, locate the H8 microprocessor and EEPROM IC
packages on the I/O Board.
Important: The larger IC package that is to be removed in the next
step is the H8 microprocessor (with internal EPROM). This package
can be very difficult to remove. In addition, damage to surrounding
components can occur if care is not taken.
Important: It is recommended that a chip (integrated circuit) puller
be used. If a puller is not available, a less desirable alternative is to
use a small, flat blade screwdriver. The screwdriver is first inserted
under one end of the H8 microprocessor and then the other end. This
method can be used to help lift the IC from its socket. If the
screwdriver method is used, extreme caution must be taken so that
surrounding components and board traces are not damaged.
f) Carefully remove the H8 microprocessor from its socket noting notch
orientation. Insert the H8 into the new I/O Board (note orientation –
notch on IC must align with notch on socket). Extreme care must be
used to assure that all pins are properly aligned and inserted.
When all pins are aligned and inserted, firmly press the package down
until it is fully seated. Inspect all pins to assure that no damage has
occurred.
g) Carefully remove the EEPROM from its socket on the old board,
noting notch orientation. Insert the EEPROM (noting orientation) into
the socket on the new board. Care must be used to assure that all
pins are properly aligned and inserted. When all pins are aligned
and inserted, firmly press the package down until it is fully seated.
Inspect all pins to assure that no damage has occurred.
Important: The EEPROM contains the programmed parameters and
must be moved to the new board. If it is not moved, re-programming
of the drive parameters will be required.
h) Replace the I/O Board and Display & Keypad Module, assuring that
connector pins are aligned properly and any cables removed are
re-connected.
i) Replace drive cover, remove wrist strap & check for proper operation.
