The Status menu is used to view information about the
configuration and operation of the system.
Command displays the final command in mA.
Command displays the final command in %.
Position displays the valve position in %.
PS displays the supply pressure.
PA displays the pressure in port A. This is the primary port if
using a poppet-style relay module.
PB displays the pressure in port B. This is the primary port if
using a spool-style relay module.
Friction displays the friction of the actuator/valve assembly.
Actuation Ratio displays the force required to actuate the
valve as a percentage of the total force available. The value
is an estimate of the force that would be required to move the
valve to the end of travel, fully compressing the actuator
spring(s).
Pneumatic Leak is an estimate of leak in addition to regular
air consumption.
Temperature displays the temperature inside the positioner.
Valve Cycles are counted each time the positioner changes
direction. The movement must be beyond a dead-band
window. This window is set to 0.5% as a default, but can be
changed using the DTM.
Valve Travel is counted in small increments every time the
valve moves beyond the dead-band window. The travel is
displayed in % of full stroke.
Card 1 Value shows the configuration and status of the
auxiliary card in slot 1. A tripped state is represented by a 0.
A nominal state is represented by a 1.
Card 2 Value shows the configuration and status of the
auxiliary card in slot 2. A tripped state is represented by a 0.
A nominal state is represented by a 1.
For example, if the Multi-Function Card (MFC) was in slot 1,
configured as an analog output (AO), and giving 12.34 mA,
the display would show "AO 1 12.34mA". If no card is in the
slot, the display will show "No Card".
For more information about auxiliary card status, see Table
12: Auxiliary Card Status.

10.3.2 Alerts and Alarms
►Alerts and Alarms
►Current Alarms (Prioritized)
►Event History
The Alerts and Alarms menu shows current and past alarms,
warnings, alerts, and calibrations.
Current Alarms displays all events that are actively sounding.
Event History displays past 32 events including alarms,
warnings, alerts, and calibrations. The event that occurred
most recently is displayed first (event 32) with later events
recorded below. Each event has a time stamp and shows if it
was turning on or off.
10.3.3 Partial Stroke Test
►Partial Stroke Test
►Start
►Last Result
The Partial Stroke Test (PST) menu provides the user the
ability to start a PST and see the results of the latest PST.
WARNING: Performing a Partial Stroke Test will result in
valve movement and the inability to operate the valve until
the test is complete. Notify proper personnel that the valve
may stroke, and make sure the valve is properly isolated if
required by plant procedures.
Start allows the user to initialize the (PST).
Last Result shows "Pass" or "Fail" from the last PST attempt.
10.3.4 Calibration
►Calibration
►Stroke/Quick Calibration
►Pressure Sensor Calibration
►Friction Calibration
►Triple Calibration
►Command Input Calibration
►Calibration Dates
The Calibration menu allows the user to calibrate the
positioner's sensors. The positioner can accurately control
with only a Quick-Cal. Typically this is all that is needed. A
friction calibration is recommended if the positioner has been
upgraded to Pro diagnostics. See section 8 STARTUP for
more details.
WARNING: Performing a calibration may result in valve
movement and the inability to operate the valve until the
calibration is complete. Notify proper personnel that the valve
may stroke, and make sure the valve is properly isolated
before proceeding.
Stroke/Quick Calibration starts an automatic calibration of the
position feedback sensor. The stroke calibration determines
the closed (0%) and open (100%) positions of the valve and
gathers information about the response of the valve (such as
