CAUTION
Do not use sealing tape on pneumatic connections. This instrument contains small passages that may become obstructed
by detached sealing tape. Thread sealant paste should be used to seal and lubricate pneumatic threaded connections.
1. Connect the DVC6005 pneumatic output to the actuator input using at least 10 mm (3/8inch) diameter tubing.
D
When using a single
acting direct digital valve controller (relay A or C) on a single
acting actuator, connect
OUTPUT A to the actuator pneumatic input.
D
When using a single
acting reverse digital valve controller (relay B) on a single
acting actuator, connect OUTPUT
B to the actuator diaphragm casing.
D
When using a doubleacting digital valve controller (relay A) on a doubleacting actuator, connect OUTPUT A and
OUTPUT B to the appropriate actuator pneumatic input. With no input current to the DVC6005, OUTPUT A is at
zero pressure and OUTPUT B is at full supply pressure when the relay is properly adjusted.
Note
To have the actuator stem extend from the cylinder with increasing input signal, connect OUTPUT A to the actuator cylinder
connection farthest from the actuator stem. Connect OUTPUT B to the cylinder connection closest to the actuator stem. To have
the actuator stem retract into the cylinder with increasing input signal, connect OUTPUT A to the actuator cylinder connection
closest to the actuator stem. Connect OUTPUT B to the cylinder connection farthest from the actuator stem.
