Badger Meter SRD/SRI Valve Positioners - Manual (Page 91)

Valve Position
This is a 4-byte real, expressed as percentage . The normal operating range for the valve position is 0 to 100% of the full scale .
Stem Setpoint
This is a 4-byte real, expressed as percentage . The Stem setpoint is the same as Setpoint unless an option other than linear
(default) is chosen in the characterization screen .
Air Supply Pressure Reading
This is a 4-byte real . The measurement reflects the current value on the optional air supply pressure sensor .
Output Pressure Reading
This is a 4-byte real . The measurement reflects the current value on an optional output pressure sensor .
Control Difference
This is a 4-byte real parameter . This measurement indicates the difference between the setpoint and actual position . The
calculation is done by the Control Processor .
Travel Position
The travel position is a 4-byte real which shows the valve position in the units selected in the Units screen .
Travel Sum
This is a 4 byte integer measurement . It contains the valve travel accumulation in full strokes . All movement, regardless of
direction, is added . Once the movement totals a full stroke (four quarter strokes open/close, a single stroke from 0% to 100%,
or many small movements in both directions which add up to a full stroke), this field is incremented . The sum may be reset by
writing a zero to this parameter (test > reset) . It is initialized to zero at the factory .
Internal Electronics Temperature
This is a 4-byte real parameter . Its value represents the PCB temperature in degrees Celsius . If the internal temperature of the
positioner is outside the Upper and Lower Temperature Limits displayed in the alarm page, an alarm will be raised . Warning:
Operating the positioner outside these limits may cause permanent damage and violate hazardous safety conditions .
Cycle Count
This is a 4 byte integer measurement . It is used to accumulate the number of changes in direction (open/close) that the
valve has encountered . One move toward open and one movement toward close, both exceeding positioner deadband,
count as one cycle . The count may be reset by writing a zero to this parameter (test->reset) . The value is initialized to zero at
the factory .
Local Enable
This function allows the device to enter into local mode . If local enable is disabled, a local master like the HHT or PC10 is not
allowed to write to the positioner at all as long as the communication to the FBM is not broken . This variable is only written by
the FBM .
Analog Setpoint Low
This is a 4-byte real and defines the minimum value of the analog setpoint . It is normally set at the factory to 4 .0 mA, but can
be adjusted higher for split ranging . If the positioner is being used in the analog mode, the calibration by Analog Setpoint
feature is available in the Calibrate menu . The Analog Setpoint feature is also available in the push button menu of the
positioner’s PCB .
