Special Construction to Support Logic

Solver Initiated Solenoid Valve Health

Monitoring

In single-acting actuator applications with a solenoid

valve installed, the DVC6000 SIS can be configured to

monitor the health of the solenoid valve test, which is

initiated by the Logic Solver. This is accomplished by

connecting the unused output port B from the

DVC6000 SIS to the pneumatic monitoring line

between the solenoid valve and the actuator, as

shown in figure 2-19. When single-acting, direct relay

C is installed, the “unused” output port is port B. When

single-acting, reverse relay B is used, the unused port

is port A.

Note

This application is called “special

application” in the Setup Wizard relay

selection.

This configuration is not possible with

a double-acting actuator or when

using relay A in single-acting mode.
