 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
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 (key
77) must be recalibrated.
Note
In the event of a power failure the
DVC6000 SIS automatically restores
the device to In Service upon
restoration of power. This is to provide
greater availability of the safety
function.
If power is inadvertently interrupted
while performing set up or
maintenance, you may need to return
the DVC6000 SIS to out of service if
the interrupted task requires that mode
of operation.
Because of the diagnostic capability of the DVC6000
SIS 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 ValveLink software
online help.

Module Base Maintenance
For DVC6010 SIS, DVC6020 SIS, DVC6030 SIS,
and DVC6005 SIS
CAUTION
To avoid affecting performance of the
instrument, take care not to damage
the module base seal or guide surface.
Do not bump or damage the bare
connector pins on the PWB assembly.
Damaging either the module base or
guide surface may result in material
damage, which could compromise the
instruments ability to maintain a
pressure seal.
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.
