Fault alarm symbol active, when prompted, Err appears.
If any fault messages exist, they are displayed here.
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.
Remedy Check attachment and pin position, set operating mode from
SAFE to MAN and re-initialize the positioner.
The measuring span of the sensor is too low.
• Pin positioned incorrectly.
• Wrong lever.
A rotational angle smaller than 11° at the positioner shaft creates
just an alarm. An angle below 6° leads to the initialization being
canceled.
Remedy Check attachment and re-initialize the positioner.
• Positioner attachment incorrect.
• Nominal travel/angle (Code 5) could not be achieved on
initialization under NOM or SUB (no tolerance downwards
permissible)
• Mechanical or pneumatic error, e.g. wrong lever selected or
supply pressure too low to move to the required position or
pneumatic fault
Remedy 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.
The initialization routine lasts too long. The positioner returns to
its previous operating mode.
• No pressure on the supply line or there is a leak.
• Supply air failure during initialization.
Remedy Check attachment and supply pressure.
Re-initialize the positioner.
