 Ensure that all caps and covers
are correctly installed before putting
this unit back into service. Failure to
do so could result in personal injury or
property damage from fire or
explosion.
CAUTION
When replacing components, use only
components specified by the factory.
Always use proper component
replacement techniques, as presented
in this manual. Improper techniques or
component selection may invalidate
the approvals and the product
specification, as indicated in table 1-1.
It may also impair operations and the
intended function of the device.
Note
If the feedback arm or feedback
arm assembly is removed from
the digital valve controller, the
travel sensor must be
re-calibrated.
Because of the diagnostic capability of the DVC6000f
digital valve controller, predictive maintenance is
available through the use of ValveLink software. Using
the digital valve controller, valve and instrument
maintenance can be enhanced, thus avoiding
unnecessary maintenance. For information on using
ValveLink software, refer to the software help.
Module Base Maintenance
WARNING
To avoid personal injury or property
damage caused by fire or explosion,
remove power to the instrument
before replacing the module base in
an area which contains a potentially
explosive atmosphere or has been
classified as hazardous.
The digital valve controller contains a module base
consisting of the I/P converter, printed wiring board
assembly, and pneumatic relay. The module base may
be easily replaced in the field without disconnecting
field wiring or tubing.
Tools Required
Table 7-1 lists the tools required for maintaining the
DVC6000f digital valve controller.
Removing the Module Base
WARNING
Refer to the Maintenance WARNING at
the beginning of this section.
To remove the module base for DVC6010f, DVC6020f
and DVC6030f digital valve controllers, perform the
following steps. Refer to figures 8-2, 8-3, and 8-4,
respectively, for key number locations.
WARNING
To avoid personal injury or equipment
damage from bursting of parts, turn
off the supply pressure to the digital
valve controller and bleed off any
excess supply pressure before
attempting to remove the module
base assembly from the housing.
1. For sliding-stem applications only, a protective
shield for the feedback linkage is attached to the side
of the module base assembly (see figures 2-1
and 2-2). Remove this shield and keep for reuse on
the replacement module. The replacement module will
not have this protective shield.
