tion being canceled.
• 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.
