Use this parameter to define the mode or scope of the Auto Adjust function.
• Full: Complete automatic adjustment
• Controller: Determine control parameters only
• Zero: Determine the 0 % position only
• Valve Range: Determine stops only
• Locked: Automatic adjustment blocked
Note
On valves where slip-stick effect is significant, valve vibration can be reduced by increasing the value of
the 'Zone' parameter.
The following values are determined during Auto Adjust:
• Direction of action of the actuator
• Direction of action of the reset spring
• Actuator travel of the actuator / final control element
• Stroke time for both directions
• Control parameters
• Offset for the I/P module
• Static friction of the actuator / final control element
• Dynamic friction of the actuator / final control element
