CAUTION
Failure to secure the cable wires in the support clips in step 9 can result in broken wires in applications with high levels of
vibration.
9. Secure the cable wires, using the support clips in the DVC6215 feedback unit (as shown in figure 2‐26), to help
prevent shifting and movement of the wires.
10. Replace and hand‐tighten all covers.

Wiring Practices

Control System Requirements

There are several parameters that should be checked to ensure the control system is compatible with the DVC6200
digital valve controller.

HART Filter

Depending on the control system you are using, a HART filter may be needed to allow HART communication. The
HART filter is a passive device that is inserted in field wiring from the HART loop. The filter is normally installed near the
field wiring terminals of the control system I/O (see figure 2‐27). Its purpose is to effectively isolate the control system
output from modulated HART communication signals and raise the impedance of the control system to allow HART
communication. For more information on the description and use of the HART filter, refer to the appropriate HART
filter instruction manual.
To determine if your system requires a filter contact your Emerson Process Management sales office.
Note
A HART filter is typically NOT required for any of the Emerson Process Management control systems, including PROVOXt, RS3t,
and DeltaVt systems.
