D Travel Sensor Motion (TRAVEL_SENSOR_MOTION [67.3])
WARNING
Setting the Travel Sensor Motion incorrectly may cause the valve to move. 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.
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.
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 "Towards Top of Instrument/CCW." If it causes the magnet assembly
to move down, or the actuator shaft to rotate clockwise, enter "Away From Top of Instrument/CW." For instruments
with relay B.
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 "Towards Top of Instrument/CCW." If it causes the magnet assembly
to move down, or the actuator shaft to rotate clockwise, enter "Away From Top of Instrument/CW."
D Enter the Lever Style (LEVER_STYLE [102.10]) for rotary actuators as either Pivot Point or Rack and Pinion.
D Defines the Lever Arm Length (LEVER_ARM_LENGTH [102.11]) for rotary actuators.
D Enter the actuator Effective Area (EFFECTIVE_AREA [102.2]) in in
D Stroking Time Open (STROKING_TIME_OPEN [102.8])— enter the time required to stroke the valve from closed to
open.
D Stroking Time Close (STROKING_TIME_CLOSE [102.9])— enter the time required to stroke the valve from open to
close.
D Air (AIR [102.3])— select Opens or Closes, indicating the effect of increasing air pressure on the valve travel.
D Upper Bench Set (UPPER_BENCH_SET [102.5])— enter the upper actuator operating pressure .
D Lower Bench Set (LOWER_BENCH SET [102.4])— enter the lower actuator operating pressure.
D Nominal Supply Pressure (NOMINAL_SUPPLY PRESSURE [102.6])— enter the nominal instrument supply pressure .
D Enter the actuator Spring Rate (SPRING_RATE [102.7]) in lbsSin or NSm.
Reference
D Enter valve Trim Style 1 (TRIM_STYLE_1 [101.9]).
