Trip Diagnosis
C.Acc NV Media Card Write fail
185
The C.Acc trip indicates that the drive was unable to access the NV Media Card. If the trip occurs during the data transfer to
the card then the file being written may be corrupted. If the trip occurs when the data being transferred to the drive then the
data transfer may be incomplete. If a parameter file is transferred to the drive and this trip occurs during the transfer, the
parameters are not saved to non-volatile memory, and so the original parameters can be restored by powering the drive
down and up again.
Recommended actions:
• Check NV Media Card is installed / located correctly
• Replace the NV Media Card
C.cPr NV Media Card file/data is different to the one in the drive
188
A compare has been carried out between a file on the NV Media Card and the drive, a C.cPr trip is initiated if the
parameters on the NV Media Card are different to the drive.
Recommended actions:
•Set Pr mm.000 to 0 and reset the trip
• Check to ensure the correct data block on the NV Media Card has been used for the compare
C.d.E NV Media Card data location already contains data
179
The C.d.E trip indicates that an attempt has been made to store data on a NV Media Card in a data block which already
contains data.
Recommended actions:
• Erase the data in data location
• Write data to an alternative data location
C.dAt NV Media Card data not found
183
The C.dAt trip indicates that an attempt has been made to access a non-existent file on the NV Media Card.
No data is transferred.
Recommended actions:
• Ensure data file number is correct
C.Err NV Media Card data structure error
182
The C.Err trip indicates that an attempt has been made to access the NV Media Card but an error has been detected in the
data structure on the card. Resetting the trip will cause the drive to erase and create the correct folder structure. On an SD
card, whilst this trip is present, missing directories will be created and if the header file is missing it will be created. The
cause of the trip can be identified by the sub-trip.
Recommended actions:
• Erase all the data block and re-attempt the process
• Ensure the card is located correctly
• Replace the NV Media Card
C.FuL NV Media Card full
184
The C.FuL trip indicates that an attempt has been made to create a data block on a NV Media Card, but there is not enough
space left on the card. No data is transferred.
Recommended actions:
• Delete a data block or the entire NV Media Card to create space
• Use a different NV Media Card
Sub-trip Reason
1 The required folder and file structure is not present
2 The 000.DAT file is corrupted
3 Two or more files in the <MCDF\> folder have the same file identification number
