Cause
Transmitter DAT:
1. T-DAT is defective.
2. T-DAT is not plugged into the
amplifier board or is missing.
Transmitter DAT:
Error accessing the adjustment
values stored in the T-DAT.
Due to different software versions, I/
O board and amplifier board are only
partially compatible (possibly
restricted functionality).
!
Note!
– This message is only listed in the
error history.
– Nothing is displayed on the
display.
Transmitter DAT:
Data backup (downloading) to T-
DAT failed, or error when accessing
(uploading)
the calibration values stored in the
T-DAT.
Internal communication fault on the
amplifier board.
No data reception between amplifier
and I/O board or faulty internal data
transfer.
Power supply interrupted.
Error message appears during device
startup in custody transfer mode
after a power failure.
Remedy / spare part
1. Replace the T-DAT.
Check the spare part set number to ensure that
the new, replacement DAT is compatible with
the measuring electronics.
2. Plug the T-DAT into the amplifier board.
1. Check whether the T-DAT is correctly plugged
into the amplifier board.
2. Replace the T-DAT if it is defective.
Before replacing the DAT, check that the new,
replacement DAT is compatible with the
measuring electronics. Check the:
– Spare part set number
– Hardware revision code
3. Replace measuring electronics boards if
necessary.
Module with low software version has either to be
actualized by ToF Tool - Fieldtool Package with the
required SW version or the module has to be
replaced.
1. Check whether the T-DAT is correctly plugged
into the amplifier board.
2. Replace the T-DAT if it is defective.
Before replacing the DAT, check that the new,
replacement DAT is compatible with the
measuring electronics. Check the:
– Spare part set number
– Hardware revision code
3. Replace measuring electronics boards if
necessary.
Remove the amplifier board.
Check the BUS contacts.
Confirm with the ENTER key or reset via the
auxiliary input (status input).
