When fault alarms exist, they are displayed here.
50
x > range The value supplied by the measuring signal is either too high or
too low, the measuring sensor is close to its mechanical limit.
• Pin positioned incorrectly.
• Bracket slipped in case of NAMUR attachment or positioner is
not central.
• Follower plate incorrectly attached.
Status classification [Maintenance required]
Recommended action Check attachment and pin position, set operating mode from
SAFE to MAN and re-initialize the positioner.
51
∆
x < range The measuring span of the sensor is too low.
• Pin positioned incorrectly.
• Wrong lever.
A rotational angle smaller than 16° at the positioner shaft creates
just an error message. An angle below 9° leads to the initializa-
tion being canceled.
Status classification [Maintenance required]
Recommended action Check attachment and re-initialize the positioner.
52 Attachment • Positioner attachment incorrect.
• Nominal travel/angle (Code
5 ) could not be achieved during
initialization under NOM (no tolerance downwards
permissible).
• Mechanical or pneumatic fault, e.g. wrong lever selected or
supply pressure 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 an initialization under MAX.
After initialization has been completed, the Code
5 indicates the
maximum achieved travel or angle.
