Functionality of the RDx-xxxDT:
The RDx can operate as a 3-position or 4-position actuator. The 4
th
position is enabled by turning Dip 8 ON.
3-pos Functionality (Dip 8 OFF)
Input#1
(Pin 1)
Input#2
(Pin 2)
Action taken
High
High
Moves to or remains in center position
Low
High
Moves to or remains in right position
High
Low
Moves to or remains in left position
Low
Low
Moves to or remains in right position (Input#1 has
precedence over Input #2)
The feedback from the RDx-xxxDT is as follows:
Output#1
(Pin 3)
Output#2
(Pin 4)
Meaning
High = 4.5vDC Low = 0.8vDC

Actuator is moving, or has stalled and given up trying to
reach a requested position.
You may retry to reach any position by cycling alternate
inputs and trying the original again. Repeated failures to
reach the position will require troubleshooting.

Actuator has stalled. The stall can be cleared by making
the actuator turn in the other direction.
Direction of rotation and using Input 1
To change the direction of rotation on the actuator change the setting on Dip12 and power up the actuator again.
VERY IMPORTANT:
Input 1 must always be used if only one input is used to operate the valve.
When the actuator is operated using input 1 an automatic calibration is done every time the valve
is actuated. This does not happen on input 2.
