FAULT: Short-circuit SCI
nn
<-> SCI
nn
SCI
n
<-> SCI
n
describes between which
S
hort
C
ircuit
I
solators the short-circuit
is located.
nn
= A, B, 0, 1, 2, 3, 4, 5, 6 or up to 128
. A & B are the built-in isolators in the
FT128 A-direction and B-direction respectively.
If no SCI is used the information will always be:
SCI
A
<-> SCI
B
.
If one SCI (no. 0) is used, the information will be:
SCI
A
<-> SCI
0
or
SCI
0
<-> SCI
B
...and so on.
There will also be a "FAULT: No reply ….." message for each unit that FT128
cannot find.
If several short circuits exist on the loop the message shows the last isolator
before the break in the A-direction (including the following isolator). There will
also be shown "FAULT: Several faults …".
NOTE: Each 10th minute a check is performed if all short-circuits are corrected
(repaired). If so, the communication automatically returns to communicate in one
direction only.
The fault has to be acknowledged, i.e. and it can last up to 10 minutes after the
acknowledgement before the communication returns to communicate in one
direction only.
NOTE: This fault might be incorrectly shown if the SA-SB cables are mixed. If
no short circuit can be found, run “check loop” from EBLWin to get correct
information.
FAULT: Site specific data (SSD)
The Site Specific Data (SSD) is not downloaded correctly (a checksum fault, etc.).
A new SSD download (via EBLWin) is required. If the fault cannot be corrected it
is very serious. Call for service personnel / engineer immediately.
FAULT: Site specific data (SSD), AAU x
Alert Annunciation Unit 1736
There is no SSD (Site Specific Data) downloaded to the unit or something is wrong
in the downloaded SSD.
FAULT: Site specific data (SSD), EPU x
External Presentation Unit 1728
There is no SSD (Site Specific Data) downloaded to the unit or something is wrong
in the downloaded SSD.
FAULT: Supervised input x addr xxx
A fault on the supervised input x on 4461/4462.
Check the cables / connections (cut-off or short-circuit).
FAULT: Wrong type, expansion board x
This is valid for the I/O Matrix board 4582 no. x connected on the COM loop inside
or outside the FT128.
The board is not the same type as programmed in the SSD. Change the
programming (via EBLWin) or the board.
