Travel Sensor Motion (TRAVEL_SEN_MOTION
[42.3]) establishes the proper valve travel sensor
(feedback) rotation/movement.
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.
For quarter-turn actuators determine rotation by
viewing the end of the actuator shaft.
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.”
Lever Style
Enter the lever style (LEVER_STYLE [85.10]) for
rotary actuators as either Pivot Point or Rack and
Pinion.
Lever Arm Length
Defines the lever arm length (MOMENT_ARM [85.11])
for rotary actuators.
Effective Area
Enter the actuator effective area (EFFECTIVE_AREA
[85.2]) in in
2
, cm
2
, or mm
2
.
Air
Select Opens or Closes, indicating the effect of
increasing air pressure (AIR [85.3]) on the valve travel.
Upper Bench Set
Enter the upper actuator operating pressure
(UPPER_BENCH_SET [85.5]).
Lower Bench Set
Enter the lower actuator operating pressure
(LOWER_BENCH SET [85.4]).
Nominal Supply Pressure
Enter the nominal instrument supply pressure
(NOMINAL_SUPPLY PRESSURE [85.6]).
Spring Rate
Enter the actuator spring rate (SPRING_RATE [85.7])
in lbs
in or N m.
Reference
Trim Style 1
Enter the valve trim style (TRIM_STYLE_1 [84.9]).
Trim Style 2
Enter the valve trim style (TRIM_STYLE_2 [84.10]).
Stroking Time Open
Enter the time required to stroke the valve from closed
to open (STROKING_TIME_OPEN [85.8]).
Stroking Time Close
Enter the time required to stroke the valve from open
to close (STROKING_TIME_CLOSE [85.9]).
