actuator model, then you will be prompted for setup
parameters such as:
Actuator Style (select spring & diaphragm, piston
single-acting with spring, piston double-acting with
spring)
Valve Style (select the valve style, rotary or sliding
stem)
On Loss of Instrument Signal, (valve opens or
closes). See Zero Power Condition in the Detailed
Setup section.
Feedback Connection (select Rot-All, SS-roller, or
SStem-Standard). See Feedback Connection in the
Detailed Setup section.
Partial Stroke Start Point (select the start point for
the Partial Stroke Test; either Valve Open or Valve
Close).
LCP100 Local Control Panel (indicate if the
instrument is connected to an LCP100 local control
panel).
Travel Sensor Motion (increasing air pressure
causes the travel sensor shaft to rotate clockwise or
counterclockwise), the Setup Wizard will ask if it can
move the valve to determine travel sensor motion.
If you answer yes, the instrument may stroke the valve
the full travel span to determine travel sensor rotation.
If you answer No, then you will have to specify the
rotation for increasing air pressure (determine the
rotation by viewing the end of the travel sensor shaft).
See Travel Sensor Motion in the Detailed Setup
section.
Tuning Set (see Tuning Set in the Detailed Setup
section).
After choosing the appropriate tuning set, a message
appears on the display, asking if you would like to
download factory defaults for Setup. Yes is
recommended for Initial Setup. Refer to table 3-3 for
factory download defaults.
Follow the prompts on the Field Communicator
display. The calibration procedure uses the valve and
actuator stops as the 0% and 100% calibration points.
For additional information, refer to Auto Calibrate
Travel in the Calibration section.
Once Auto Calibration is complete, you will be asked
to enter the desired stroke test speed (default is
0.25%/sec). An additional automatic PST calibration is
run to determine the default value or the partial stroke
pressure limit for single acting actuators (this will be
differential pressure for double acting) and pressure
set point for End Point Pressure Control.
When calibration is complete, you are asked if you
wish to adjust the relay (double-acting only). Select
yes to adjust the relay. For additional information, refer
to Relay Adjustment in the Calibration section.

1. Analog mode only − DIP switch set to Pt-Pt.
2. Digital mode only. − DIP switch set to Multi.
3. In firmware 3 thru 6 this parameter is labeled Minimum Opening Time.
In firmware 10 and below this parameter should be set to zero.
4. In firmware 3 thru 6 this parameter is labeled Minimum Closing Time.
In firmware 10 and below this parameter should be set to zero.
5. Adjust to bar, kPa, or kg/cm2 if necessary.
Note
Relay Adjustment is only available for
the double-acting relay (Relay A).
After instrument setup is completed, and you have
placed the instrument in service, if End Point Pressure
Control not enabled, you will be prompted to enable it.
Select yes. Refer to Partial Stroke Variables in the
Detailed Setup section for more information.
If after completing auto setup and auto calibration the
valve seems slightly unstable or unresponsive, you
can improve operation by selecting Performance
Tuner from the Guided Setup menu. For additional
information on using the Performance Tuner to
optimize digital valve controller tuning, refer to the
Performance Tuner information below.
