• For FAILSAFE_TYPE
→ LAST GOOD (factory setting):
If a valid output value was available before the failure:
If no valid output value was available before the failure:
• For FAILSAFE_TYPE
→ WRONG VALUE:
For status information, see the table in the following section.
!
Note!
The FAILSAFE_TYPE function can be configured in the corresponding Analog Input function block
1 to 6 or Totalizer function block 1 to 3 by means of an operating program (e.g. FieldCare).

Depicted on the local display:
S = System error
$ = Fault message (with an effect on the outputs)
! = Notice message (without any effect on the outputs)
001 S: CRITICAL FAILURE
$: # 001 0x0F BAD Device Failure Constant ROM / RAM
failure Cause:
ROM/RAM error. Error when accessing the
program memory (ROM) or random access
memory (RAM) of the processor.
Remedy:
Replace the amplifier board.
011 S: AMP HW EEPROM
$: # 011 0x0F BAD Device Failure Constant Amplifier EEPROM
failure Cause:
Amplifier with faulty EEPROM
Remedy:
Replace the amplifier board.
012 S: AMP SW EEPROM
$: # 012 0x0F BAD Device Failure Constant Amplifier EEPROM
data inconsistent Cause:
Error when accessing data of the measuring
amplifier EEPROM
Remedy:
Perform a "warm start" (= start the measuring
system without disconnecting main power).
