extend from the cylinder with increasing input signal, connect OUTPUT A to the upper actuator cylinder connection. Connect OUTPUT B to the lower cylinder connection. To have the actuator stem retract into the cylinder with increasing input signal, connect OUTPUT A to the lower actuator cylinder connection. Connect OUTPUT B to the upper cylinder connection.
Special Construction to Support Solenoid Valve Testing Note Solenoid valve testing is only available for instrument level ODV.
In single‐acting actuator applications with a solenoid valve installed, the DVC6200 can be configured to test the operation of the solenoid valve. This is accomplished by connecting the “unused” output port from the DVC6200 to the pneumatic line between the solenoid valve and the actuator, as shown in figure 2‐22. 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. Figure 2‐22. Pneumatic Hookup for Solenoid Testing (Instrument Level ODV only) 24/48 VDC 110/220 VAC, etc.
