Mechanical Interfaces

Critical Alarm Status

Do not continue to operate the unit until the failure has

been eliminated.

Actuator OOR Failure

This Alarm indicates a critical state for the

operation of the device.
The valve position is not within permissible

range of mechanical stops that were

determined during the initial start-up . The

fingerprint data differ and are outside the

allowed range (valve position: –5…105%) .

Check mechanical connection between the positioner and

the actuator / valve .
Perform Endpoints Calibration .
This can also be a sign of wear on the plug or seat . Check if

they are still in tact .

Difference between applied analog or

digital setpoint and the corresponding valve

position . The values exceed the allowed limit

in connection with a specified time limit . The

default values are 5% within 60 Seconds .

Check if supply pressure is adequately supplied . Verify

the tuning parameters . Check mechanical connection to

the actuator and valve . Check configured alarming values

under Alarms/Control Difference Alarm .
If pressure sensors are applied and the Load Factor is

available, check if Load Factor/High Friction Alarm is active .

In this case the friction of the packing is too high and

causes the stem movement to block .
Refer to troubleshooting section of MI .

Internal Electronic Interfaces
Current Loop

I/P Motor

Failure

Connection of I/P converter to electronic

board is faulty .

Connect I/P- .converter to the electronic board . Restart the

positioner . If the error is still active, replace the positioner .

Potentiometer Failure

Connection of potentiometer to electronic

board is faulty .

Connect potentiometer to the electronic board . Restart the

positioner . If the error is still active, replace the positioner .
