active. The Dead Zone is configurable from 0% to 2%,
corresponding to a symmetric window from 0% to
+/−2% around the Primary Setpoint. Default value is
0.25%.
Instrument (1-2-5)
Select Configure, Detailed Setup, and Instrument.
Follow the prompts on the Field Communicator display
to configure the following Instrument parameters:
General, Units, Analog Input Range, Relay Type, Zero
Power Condition, Maximum Supply Pressure, Auxiliary
Terminal Action, Instrument Date and Time, and Calib
Status and Type.
General (1-2-5-1)
 HART Tag—Enter an up to 8 character HART
tag for the instrument. The HART tag is the easiest
way to distinguish between instruments in a
multi-instrument environment. Use the HART tag to
label instruments electronically according to the
requirements of your application. The tag you assign is
automatically displayed when the Field Communicator
establishes contact with the digital valve controller at
power-up.
 Message—Enter any message with up to 32
characters. Message provides the most specific
user-defined means for identifying individual
instruments in multi-instrument environments.
 Descriptor—Enter a descriptor for the application
with up to 16 characters. The descriptor provides a
longer user-defined electronic label to assist with more
specific instrument identification than is available with
the HART tag.
 Date—Enter a date with the format MM/DD/YY.
Date is a user-defined variable that provides a place to
save the date of the last revision of configuration or
calibration information.
 Valve Serial Number—Enter the serial number
for the valve in the application with up to 12
characters.
 Instrument Serial Number—Enter the serial
number on the instrument nameplate, up to 12
characters.
 Polling Address—If the digital valve controller is
used in point-to-point operation, the Polling Address is
0. When several devices are connected in the same
loop, such as for split ranging, each device must be
assigned a unique polling address. The Polling
Address is set to a value between 0 and 15. To
change the polling address the instrument must be
Out Of Service.

For the Field Communicator to be able to
communicate with a device whose polling address is
not 0, it must be configured to automatically search for
all or specific connected devices.
Units (1-2-5-2)
 Pressure Units—Defines the output and supply
pressure units in either psi, bar, kPa, or kg/cm
2
.
 Temperature Units—Degrees Fahrenheit or
Celsius. The temperature measured is from a sensor
mounted on the digital valve controller’s printed wiring
board.
 Analog In Units—Permits defining the Analog
Input Units in mA or percent of 4-20 mA range. Only
for instruments in a 4-20 or 0-20 mA installation
(point-to-point operation).
Analog Input Range (1-2-5-3)
 Input Range Hi—Permits setting the Input Range
High value. Input Range High should correspond to
Travel Range High, if the Zero Power Condition is
configured as closed. If the Zero Power Condition is
configured as open, Input Range High corresponds to
Travel Range Low. See figure 4-5.
 Input Range Lo—Permits setting the Input Range
Low value. Input Range Low should correspond to
Travel Range Low, if the Zero Power Condition is
configured as closed. If the Zero Power Condition is
configured as open, Input Range Low corresponds to
Travel Range High. See figure 4-5.
