206 S SAVE T-DAT
! # 206
0x0F BAD Device Failure Constant Restore from T-
DAT failed
Cause:
System error. Data backup to T-DAT failed, or error
when accessing the calibration values stored in the
T-DAT.
Remedy:
1. Verify that the T-DAT is correctly plugged into
the amplifier board, → Page 139 ff. Replace T-
DAT if defective. Spare parts → Page 137 ff.
Check the spare part set number to ensure that
the new, replacement DAT is compatible with
the measuring electronics.
2. Replace measuring electronics boards if
necessary.

S: STACK CUR OUT n
$: # 339...342
0x0F BAD Device Failure Constant Temp. Buf. not
cleared
Cause:
The temporarily buffered flow portions (measuring
mode for pulsating flow) could not be cleared or
output within 60 seconds.
Remedy:
1. Change the upper or lower limit setting, as
applicable.
2. Increase or reduce flow, as applicable.
Recommendations in the event of fault category =
FAULT MESSAGE ($):
– Configure the fault response of the output to
“ACTUAL VALUE”, so that the temporary buffer
can be cleared. → Page 137
– Clear the temporary buffer by the measures
described under Item 1.
