When fault alarms exist, they are displayed here.
50 x > permissible
range
Value of measuring signal too high or too low; the lever operates near its
mechanical stops.
• Pin not mounted properly
• Bracket slipped in case of NAMUR attachment or positioner is off center.
• Follower plate not mounted properly.
Status classification
[Maintenance required]
Recommended action Check attachment and pin position, set operating mode from SAFE to
MAN and re-initialize the positioner.
51
Δx < permissible
range
Insufficient measuring span of the lever.
• Pin not mounted properly
•
Wrong lever
An angle of rotation smaller than 16° at the positioner shaft only gener-
ates an alarm. An angle below 9° leads to the initialization being can-
celed.
Status classification
[Maintenance required]
Recommended action Check attachment and re-initialize the positioner.
52
Attachment
• Invalid positioner attachment
•
Nominal travel/angle (Code 5) could not be achieved during NOM ini
-
tialization (no tolerance downwards permissible).
• Mechanical or pneumatic fault, e.g. wrong lever selected or supply pres-
sure too low to move to the required position.
Status classification
[Maintenance required]
Recommended action Check attachment and supply pressure. Re-initialize the positioner.
Under certain circumstances, it may be possible to check the maximum
travel/angle by entering the actual pin position and then performing a
MAX initialization.
After initialization has been completed, the Code 5 indicates the maximum
achieved travel or angle.
