D Feedback Connection —refer to table 3‐5 for Feedback Connection options. Choose the assembly that matches the
actuator travel range.
D Travel Sensor Motion— establishes the proper valve travel sensor (feedback) rotation/movement. For quarter‐turn
actuators determine rotation by viewing the rotation of the magnet assembly from the back of the instrument.
WARNING
If you answer YES to the prompt for permission to move the valve when setting the Travel Sensor Motion, the instrument
will move the valve through its full travel range. To avoid personal injury and property damage caused by the release of
pressure or process fluid, isolate the valve from the process and equalize pressure on both sides of the valve or bleed off the
process fluid.
Note
Travel Sensor Motion in this instance refers to the motion of the magnet assembly. Note that the magnet assembly may be
referred to as a magnetic array in user interface tools.
For instruments with relay A or C If increasing air pressure at output A causes the magnet assembly to move up, or the
actuator shaft to rotate counterclockwise, enter "Counterclockwise/Towards Top of Instrument." If it causes the
magnet assembly to move down, or the actuator shaft to rotate clockwise, enter "Clockwise/Away From Top of
Instrument."
For instruments with relay B If decreasing air pressure at output B causes the magnet assembly to move up, or the
actuator shaft to rotate counterclockwise, enter "Counterclockwise/Towards Top of Instrument." If it causes the
magnet assembly to move down, or the actuator shaft to rotate clockwise, enter "Clockwise/Away From Top of
Instrument."
D Lever Style— enter the lever style for rotary actuators as either Pivot Point or Rack and Pinion.
D Lever Arm Length—defines the lever arm length for rotary actuators.
D Effective Area — enter the actuator effective area in in
D Air— select Opens or Closes, indicating the effect of increasing air pressure on the valve travel.
D Upper Bench Set— enter the upper actuator operating pressure.
D Lower Bench Set— enter the lower actuator operating pressure.
D Nominal Supply Pressure— enter the nominal instrument supply pressure.
D Spring Rate— enter the actuator spring rate in lbsSin or NSm.
Reference
D Trim Style 1— enter the valve trim style.
D Trim Style 2— enter the valve trim style.
D Stroking Time Open— enter the time required to stroke the valve from closed to open.
D Stroking Time Close— enter the time required to stroke the valve from open to closed.
Note
Stroking Time Open and Stroking Time Close are used as a point of reference only; they do not reflect the actual time required to
stroke the valve from closed to open or open to closed.
