Type Enable Potential causes and corrective actions
F Fixed Cause
The system has sense lines which indicate whether or not the cable to the
system interface board is attached. This cable attached to the system via
the fifty pin connector on the main control board. If this cable is not at‐
tached a "System Interface Conn" fault will be generated.
Action
1. Check that the cable to the system interface board is connected prop‐
erly.
2. Replace cable to system interface board.
3. Replace DCR.
4. Contact Siemens customer service.
F Fixed Cause
The system has sense lines which indicate whether or not the fiber optic
board is installed. If the fiber optic board is not installed properly a "Fiber
Optic Board Conn" fault will be generated.
Action
1. Replace DCR.
2. Contact Siemens customer service.
F Fixed Cause
The NXGpro's main FPGA incorporates a CRC check system which detects
errors in the contained logic. This check system has an output which is fed
into the GLUE CPLD. The "FPGA CRC Error Fault" is generated when the CRC
error signal is received from the GLUE logic.
Action
1. Toggle control power.
2. Contact Siemens customer service.
F Fixed Cause
The system has sense lines which indicate whether or not each of the four
possible fiber optic expansion boards is installed. A "F.O. Exp Bd Not found"
fault will be generated if any the following conditions is satisfied:
1. The number of cells per phase parameter is greater than four and the
fiber optic expansion board for rank five is not installed.
2. The number of cells per phase parameter is greater than five and the
fiber optic expansion board for rank six is not installed.
3. The number of cells per phase parameter is greater than six and the
fiber optic expansion board for rank seven is not installed.
4. The number of cells per phase is equal to eight and the fiber optic
expansion board for rank eight is not installed.
Action
1. Check that the proper number of cells is entered in the system param‐
eter menus.
2. Replace DCR.
3. Contact Siemens customer service.
