Figure 2-19. Pneumatic Hookup for Solenoid Testing
Special Construction to Support Solenoid
Valve Testing
In single-acting actuator applications with a solenoid
valve installed, the DVC6000 can be configured to test
the operation of the solenoid valve. This is
accomplished by connecting the “unused” output port
from the DVC6000 to the pneumatic 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
Solenoid valve testing is only available
for instrument level PD and ODV.
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.
Vent
WARNING
Personal injury or property damage
can occur from cover failure due to
overpressure. Ensure that the
housing vent opening is open and
free of debris to prevent pressure
buildup under the cover.
