System error messages

Serious system errors are always recognized by the instrument as "Fault message", and are shown
as a lightning flash ($) on the display!
Caution!
In the event of a serious fault, a flowmeter might have to be returned to the manufacturer for repair.
Important procedures must be carried out before you return a flowmeter to Endress+Hauser
→ ä 6.
Always enclose a duly completed "Declaration of contamination" form. You will find a preprinted
blank of this form at the back of this manual.
Note!
• The listed error message types below correspond to the factory setting.
• Also observe the information → ä 35.

Depicted on the local display:
S = System error
$ = Fault message (with an effect on the outputs)
! = Notice message (without any effect on the outputs)

Remedy / spare part
Replace the amplifier board.
Replace the amplifier board.
The EEPROM data blocks in which an error has
occurred are displayed in the
"TROUBLESHOOTING" function.
Press ENTER to acknowledge the errors in question;
default values are automatically inserted instead of
the erroneous parameter values.
!
Note!
The measuring device has to be restarted if an error
has occurred in the totalizer block (see also error No.
111 / CHECKSUM TOTAL.).
1. Replace the S-DAT.
Check the spare part set number to ensure that
the new, replacement DAT is compatible with
the measuring electronics.
2. Plug the S-DAT into the amplifier board.
1. Check whether the S-DAT is correctly plugged
into the amplifier board.
2. Replace the S-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.
