ACS1 DataRcvd
Upon power up the IFB board receives initial conrmation
data from all the devices that are connected to the ACS1
channel. Problems with this conrmation are indicated with this
parameter. There are 8 possible conditions indicated. These
are described as follows:
ErrAll: IFB did not receive initial conrmation data from
any of the devices on the ACS1 communication channel.
This generally indicates a physical break in the ACS1
communication loop wiring between the IFB board and the
A4P and A5P boards or lack of power to both the A4P and A5P
boards.
F1F2Err: IFB did not receive initial conrmation data from
the OF2 nor OF1 on the ACS1 communication channel. This
generally indicates a defect in both the boards controlling OF1
(A4P or A5P) and OF2 (A5P).
INVF2Err: IFB did not receive initial conrmation data from
the INV nor OF2 on the ACS1 communication channel. This
generally indicates a defect in both the boards controlling INV
(A4P) and OF2 (A5P).
F2Err: IFB did not receive initial conrmation data from the
OF2 on the ACS1 communication channel. This generally
indicates a defect in the board controlling OF2 (A5P).
INVF1Err: IFB did not receive initial conrmation data from
the INV or OF1 on the ACS1 communication channel. This
generally indicates a defect in both the boards controlling INV
(A4P) and OF1 (A4P or A5P).
F1Err: IFB did not receive initial conrmation data from the
OF1 on the ACS1 communication channel. This generally
indicates a defect in the board controlling OF1 (A4P or A5P).
INVErr: IFB did not receive initial conrmation data from the
INV on the ACS1 communication channel. This generally
indicates a defect in the board controlling INV (A4P).
AllOK: All initial conrmation data has been received from all
the devices on the ACS1 communication loop.
ACS3 DataRcvd
Upon power up the IFB board receives conrmation data
from all the devices that are connected to the ACS3 channel.
Problems with this conrmation are indicated with this
parameter. There are 2 possible conditions indicated. These
are described as follows:
Error: IFB did not receive initial conrmation data from
the EVB board on the ACS3 communication channel.
This generally indicates a physical break in the ACS3
communication loop wiring between the IFB board and the
EVB board, lack of power to the EVB board or a defect in the
EVB board.
OK: All initial conrmation data has been received from all the
EVB board on the ACS3 communication channel.
