Fault display Type Enable Potential causes and corrective actions
System Interface Conn 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 󹪝fty 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.
Fiber Optic Board Conn F Fixed Cause
The system has sense lines which indicate whether or not the 󹪝ber optic
board is installed. If the 󹪝ber optic board is not installed properly a "Fiber
Optic Board Conn" fault will be generated.
Action
1. Replace DCR.
2. Contact Siemens customer service.
FPGA CRC Error Fault
Note: This feature is not ap‐
plicable to NXGPro+ control.
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.O. Exp Bd Not found F Fixed Cause
The system has sense lines which indicate whether or not each of the four
possible 󹪝ber optic expansion boards is installed. A "F.O. Exp Bd Not found"
fault will be generated if any the following conditions is satis󹪝ed:
1. The number of cells per phase parameter is greater than four and the
󹪝ber optic expansion board for rank 󹪝ve is not installed.
2. The number of cells per phase parameter is greater than 󹪝ve and the
󹪝ber optic expansion board for rank six is not installed.
3. The number of cells per phase parameter is greater than six and the
󹪝ber optic expansion board for rank seven is not installed.
4. The number of cells per phase is equal to eight and the 󹪝ber 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.
