# Memory (10)

An error has occurred in connection with the non volatile memory. The cause of the error can be detailed by the Sub-ID:

### 0 - reading from backup failed

The reading from backup failed. There is saved a checksum (CRC) at each store operation in addition to the data. While reading the data the checksum will be compared with the reading data. The error will occur when the compare was not correct.

This can be different causes:

- the stack is damaged e.g. by electromagnetic influences.

- the saving of the parameter settings was interrupted e.g. by a blackout

- it was never saved a parameter setting with this number.

When the error occurred the parameter setting will be operated with factory settings

### 1 - Verify after store failed

After saving the parameter values the checksum (CRC) does not match the current parameter values.

Storing the parameter values has failed. There is not a valid parameter setting after the occurrence of the this error in the selected storage area.

The loading of parameter setting will fail with his error (Sub ID 0 or 2).

The error indicates a defective memory element and can only be remedied by replacement of the device.

### 2 - reading from Factory backup failed

The error corresponds to Sub-ID 0 with exception that in this case the memory area is affected for calibration.

## Troubleshooting

An error with Sub-ID 0 and 2 can be solved by storing the current parameter set in non volatile memory area. The storage process is described here.

An error with Sub-ID 1 can only be remedied by replacing the defective device.
