10.3 Menu Features
10.3.1 Status
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 %.
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.
10.3.2 Alerts and Alarms
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.
10.3.3 Partial Stroke Test
The Partial Stroke Test (PST) menu provides the user the
ability to start a PST and see the results of the latest PST.
CAUTION: 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
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.
CAUTION: 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
valve stroke time) in order to determine the gains. The gains
are then set automatically. After a stroke calibration, the
positioner is ready to control. See section 8.4 Stroke
Calibration for more information.
Command Input Calibration is used to adjust the input range.
Set the lowest current (Set 0%) and the highest current (Set
100%) that will be used. The default input range is 4 to 20
mA.
The “Set 0%” value must be lower than the “Set 100%
value.
