Control loop error, the valve no longer follows the controlled variable within
tolerable times (tolerance band alarm Code 19).
• Actuator blocked
• Positioner attachment shifted subsequently
• Supply pressure no longer suffices.
[Maintenance required]
Check attachment.
Zero point incorrect
Error can occur when the positioner's attachment position is shifted or when
the valve trim is worn, particularly with soft-sealed plugs.
[Maintenance required]
Check valve and attachment of the positioner. If OK, perform a zero
calibration over Code 6 (see section 7.7).
We recommend to re-initialize the positioner if zero deviates by more than 5
%.
Errors in the positioner's data section are detected detected by automatic
monitoring and corrected automatically.
[No message]
Automatic
Error in safety-relevant data that cannot be corrected automatically. Possible
cause: EMC disturbances.
The valve is moved to fail-safe position.
Maintenance alarm (cannot be classified)
Reset over Code 36. Re-initialize the positioner.
