Electrical Connections; Fieldbus Connections; Fixed Orifice Restrictions - Emerson Fisher Fieldvue DVC6030f Instruction Manual

the vent-away mounting bracket (key 74). Mount the
digital valve controller on the actuator as described in
the Installation section of this manual. The vent
connection is 3/8-inch NPT female. Typically, 12.7 mm
(0.5 inch) tubing is used to provide a remote vent.
Use 10 mm (0.275 inch) outside diameter tubing to
connect the 1/4-inch NPT digital valve controller output
connection to the pneumatic actuator input connection.
If a volume tank is used to attenuate flow instabilities,
the volume needs to be at least 1.64 liters (100 cubic
inch) but not greater than 4.1 liters (250 cubic inch).
To tune the digital valve controller for an assembly
equipped with a volume tank, select a tuning set for an
actuator with roughly the same volume. Do not use
tuning set B when a volume tank is present.
Alternatively, flow fluctuations may be attenuated by
placing a 0.9 mm (0.035 inch) fixed restriction between
the regulator and the output. A list of fixed restriction
orifice specifications is presented in table 2-2.

Electrical Connections

The following describes how to make fieldbus
connections to the digital valve controller. For
information on making other connections, such as
connecting a personal computer with AMS ValveLink
Software or connecting a simulate jumper, see the
Installation section.
WARNING
Refer to the Installation WARNING at
the beginning of this section.
WARNING
To avoid personal injury resulting
from electrical shock, do not exceed
the maximum input voltage specified
in table 1-1 of this instruction manual,
or on the product nameplate. If the
input voltage specified differs, do not
exceed the lowest specified maximum
input voltage.

WARNING
Personal injury or property damage
caused by fire or explosion may occur
if this connection is attempted in a
potentially explosive atmosphere or in
an area that has been classified as
hazardous. Confirm that area
classification and atmosphere
conditions permit the safe removal of
the terminal box cover before
proceeding

Fieldbus Connections

The digital valve controller is normally powered over
the bus from a fieldbus 9 to 32 volt power supply and
can be connected to the segment using a twisted
shielded pair or with the quick connect cable entry
option. Refer to the site preparation guide for proper
wire types, termination, length, etc. for a fieldbus
segment.
Note
As shipped from the factory, DVC6000f
Series digital valve controllers will not
move the valve when power is applied
to the instrument. To avoid the valve
going to an unknown position when
power is applied, the unit is shipped
from the factory with the transducer
block mode Out of Service. See the
Basic Setup section for information on
setup and calibration and placing the
instrument in service. The initial value
for all blocks are shown in the
parameter list for each block in the
Detailed Setup / Block Section.
