8.3.2 MULTI PCB Replacement (Part of Main Unit)
Replace the AFC1200 System Main Unit MULTI PCB as follows:
1. Ensure that the power is off. Remove any component cables connected to the PCB.
Remove the four (4) screws holding the board face plate (on front of Main Unit), and pull
out straight to remove the MULTI PCB.
2. If the replacement PCB is supplied with installed EPROMs, ensure that the software
versions and EPROM locations are the same on both boards. If not supplied, remove the
EPROMs located on the MULTI PCB, and install them on the replacement PCB. Ensure
that the EPROMs are correctly installed on the replacement MULTI PCB, and that the
EPROM identification (sticker) is present and correct. Installed EPROMs are identified by
PCB, location, and software version. Example:
MULTI
U16
A3.30
1. Follow all safety precautions to install the new PCB in reverse order of removal. When the
MULTI PCB is replaced, all the preset configuration / parameter values for fastening
operations stored on EEPROM are lost. Refer to Chapter 7 for guidance, as follows:
Manual data re-entry from hardcopy backup (7.0.2 Initial Operation) and reloading preset
values from backup magnetic disk media (7.0.3 Backup Operations).
8.3.3 FC386 PCB Replacement (Part of Main Unit)
Replace the AFC1200 Main Unit FC386 PCB with the RDISK daughter board as follows:
1. Ensure that the power is off. Remove any component cables connected to the PCB.
Remove the two (2) screws holding the board face plate (on front of Main Unit), and pull
out straight to remove the FC386 PCB.
2. If the replacement PCB is supplied with EPROMs already installed on the RDISK daughter
board, ensure that the sofware versions and EPROM locations are the same as those on
the board being replaced. If not supplied, remove the EPROMS located on the RDISK
and install them on the replacement board. Ensure that the EPROM is correctly installed
on the replacement FC386/RDISK board, and that the EPROM identification (sticker) is
present and correct. Example
RDISK
U2
A3.30
1. Verify the installation date of the lithium battery used for System CMOS memory backup.
Replace the battery if it is older than 3 years. (Refer to 8.3.4 Battery Replacement)
2. Follow all safety precautions to install the new PCB in reverse order of removal. When the
FC386 PCB is replaced, the CMOS memory will need to be setup. (Refer to 8.3.5)
8.3.4 FC386 PCB Battery Replacement
NOTE: Connect the replacement battery before removing the worn battery, or the CMOS Setup will
be lost. (Refer to 8.3.5 CMOS Setup) This battery should be replaced every three (3) years.
1. Ensure that the power is off, and disconnect the CRT & keyboard cables. Remove the two
(2) PCB face plate screws (on front of Main Unit), and pull out straight to remove.
2. Connect the new battery (Toshiba ER3VCC) to the extra connector. This is located near
the connector of the battery being replaced.
3. Disconnect and remove the old battery. Place the new
battery into the battery holder. Affix a tag to the front of
the FC386 PCB face plate to indicate the new battery
installation date, as shown at right. Reinstall the FC386 PCB in reverse order of removal.
