Tag Description (TAG_DESC [2]) is used to assign a unique description to each block within the digital valve controller
to describe the intended application for the block.
Units
D Define the output and supply Pressure Units (PRESSURE_UNITS [107]) in either psi, bar, or kPa.
D Enter the Temperature Units (TEMPERATURE_UNITS [106]) in degrees Fahrenheit or Celsius. The temperature is
measured from a sensor mounted on the digital valve controller's printed wiring board.
D Travel Units—Define the units for valve travel (TRAVEL_UNITS [30]) in inches, centimeters, millimeters or degrees.
D Length Units—Define the units for valve dimensions (LENGTH_UNITS [108]) in inches, centimeters, or millimeters.
D Area Units—Define the units for actuator area (AREA_UNITS [109]) in inches
D Spring Rate Units —Define the units for actuator spring rate (SPRING_RATE_UNITS [110]) in lbs/in
Enter the Relay Type (RELAY_TYPE [67.5]).There are three categories of relays that result in combinations from which
to select.
Relay Type: The relay type is printed on the label affixed to the relay body:
A = double‐acting or single acting
B = single‐acting, reverse
C= single‐acting, direct
Lo Bleed: The label affixed to the relay body indicates it is a low bleed version.
Zero Power Condition (ZERO_PWR_COND [67.2]) identifies whether the valve is open or closed when instrument
power is lost. If you are unsure how to set this parameter, disconnect the segment loop power to the instrument. The
resulting valve travel is the Zero Power Condition.
Enter the Maximum Supply Pressure (MAX_SUPP_PRESS [67.6]) in psi, bar, or kPa, depending on what was selected for
pressure units.
Aux Terminal Mode (AUX_MODE [67.9])
D AUX Terminal Disabled
D Simulate, when enabled, allows you to simulate Field Diagnostic alerts upon detection of short across the (+) and (-)
terminals. See page 27 for information on Simulate Active Alerts.
D PST, when enabled, allows you to initiate a partial stroke test upon detection of short across the (+) and (-)
terminals. See page 72 for additional valve and partial stroke test information.
D Release Latch detects when there is a short across the (+) and (-) terminals. When enabled, the latch will be
released.
Calibration Info
D Last Calibration Type indicates the type of the last calibration performed on the instrument. Possible values are: Not
Calibrated, Single Point Calibration, Auto Calibration, Manual Calibration.
