8.3 Replacements
WARNING:
DO NOT CONNECT OR DISCONNECT CABLES OR OTHER SYSTEM
COMPONENTS WITH POWER APPLIED. FOLLOW LOCKOUT/TAGOUT AND
OTHER APPLICABLE SAFETY PRECAUTIONS WHEN CONNECTING OR
DISCONNECTING CABLING, WIRING, AND EQUIPMENT.
NOTE: When replacing the AFC1200 System Main Controller Unit, ensure that the new Unit is
configured with the same hardware and software as the Unit being replaced.
8.3.1 Main unit Replacement (Reference Section 3.2.3)
The Main Unit controls overall operations of the AFC1200 Fastening System. The values for
System configuration and operational programs/presets are stored on the components of this
System. Values are stored on a combination of EPROM, EEPROM, battery-backed up
CMOS, and magnetic disk as follows:
UPC PCB:
Hard Disk Drive HDD
Floppy Disk Drive FDD1, FDD2 Backup of preset configuration/
parameter values for fastening
operations Magnetic disk
FC386 PCB System configuration Battery backed up CMOS
MULTI PCB Preset configuration/parameter
values for fastening operations EEPROM
FC386 PCB/RDISK daughter
board, MULTI PCB Operational Program EPROM
Location Function Memory device
To replace the AFC1200 Main Unit as a complete assembly, ensure there is no power to the
System, and disconnect all cables. Proceed as follows:
1. Ensure that the software versions and locations of EPROMs on the FC386 PCB/RDISK
daughter board and on the MULTI PCB are the same in both Main Units. (Refer to 8.3.3
FC386 PCB Replacement and 8.3.2 MULTI PCB Replacement.) Installed EPROMs are
identified by PCB, location, and software version. Example:
RDISK
A3.30
U2
1. Verify configuration of the UPC PCB. Is there a Floppy Disk Drive (FDD) or Hard Disk
Drive (HDD) installed on the UPC PCB? Configure the replacement UPC PCB as
required. Refer to 8.3.6 UPC PCB Replacement.
2. Follow all safety procedures to install the new Main Unit, and perform CMOS setup. Refer
to 8.3.5.
3. When the MULTI PCB is replaced, all the preset configuration/parameter values for
fastening operations stored on EEPROM will be 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).
