APPENDIX B – LCD MENU TREE DESCRIPTIONS
Menu Feature
Description
Menu Location
Status
The Status menu is used to view information about the configuration
and operation of the system.
1
Command (mA)
Command (mA) displays the final command in mA.
1.1
Command (Percent)
Command (Percent) displays the final command in %.
1.2
Position (Percent)
Position (Percent) displays the valve position in %.
1.3
Temperature (User Units)
Temperature (User Units) displays the temperature inside the
positioner.
1.4
Reference Pressure
PR (User Units)
PR (User Units) displays the pressure in port R. This port R is the
atmospheric reference pressure. It is subtracted from the others.
1.9
Valve Cycles (Cycles)
Valve Cycles (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.
1.13
Valve Travel (Percent)
Valve Travel (Percent) is counted in small increments every time the
valve moves beyond the dead-band window. The display of travel is
in % of full stroke.
1.14
Analog Output (AO)
The Analog Output provides a 4-20 mA feedback mechanism,
indicating the position of the valve, to the host system.
1.15
Analog Input (AI)
The Analog Input provides a 4-20 mA input mechanism to interface
with process variable transmitters.
1.16
Discrete Input (DI)
The Discrete Input provides a way for the user to either trigger a PST
or command the valve to a predetermined set point.
1.19

1.20
Alerts and Alarms
The Alerts and Alarms menu show current and past alarms,
warnings, alerts, and calibrations.
2
Current Alarms
Current Alarms displays all events that are actively sounding.
2.1
Event History
Event History displays past 32 events including alarms, warnings,
alerts, and calibrations. Displayed is the event that occurred most
recently, first (event 32) with later events recorded below. Each event
would have a timestamp and shows if it was turning on or off.

2.3
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.
3
Start
Start allows the user to initialize the (PST).
3.1
Last Result
Last Result shows “Pass” or “Fail” from the last PST attempt.
3.2
Back
3.3
Step Test
The purpose of the step test is to allow the user to easily evaluate the
performance of the positioner from the local interface
4
Start
Start allows the user to initialize the step test.
4.1
Step Size XX%
Defaulted to 50%. The Step Size shall be user settable from 2% to
100%
4.2
Back
4.3
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. Calibrate the friction calibration of
the positioner when upgrading to Pro diagnostics.
