Identifying Processor
Errors while Downloading
an Operating System The download process of the operating system by the SLC 5/03,
SLC 5/04, and SLC 5/05 processors takes up to 2.5 minutes. While the
download is in progress, the RUN and FLT status indicators remain
off. The other four status indicators - RS232, DH485 (DH
+ on the SLC
5/04 and ENET on the SLC 5/05), FORCE, and BATT - turn on and off
in a walking bit sequence. If the download is successful, these four
status indicators remain on together.
Jumper Placement
If the download is not successful, the FLT status indicator turns on
and a combination of status indicators flash on and off indicating an
error condition. The following table provides you with information
regarding error messages, possible cause(s) for the error, and
recommended action to resolve the error.
ATTENTION
Jumper J4, on the bottom corner of the motherboard, provides
write-protection from any download of a new operating
system. The out of the box position of this jumper is PROTECT,
or write-protect. Without the jumper, the processors are
write-protected. Do not place the jumper to the program
position during normal processor use.
