June 2017
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 specifications, as indicated in table 1‐2. It may also impair operations and the intended function of the device.
Note
If the feedback arm (key 79) or feedback arm assembly (key 84) is removed from the digital valve controller, the travel sensor must
be recalibrated.
Because of the diagnostic capability of the DVC6000 HW2, 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 the ValveLink software, refer to the ValveLink software
online help.

Module Base Maintenance

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.
